And, for convenience of description, the length direction of adapter is called " x direction of principal axis ", will be called " y direction of principal axis ", " z direction of principal axis " perpendicular to the direction of x direction.In addition, in Fig. 7～Fig. 9, Figure 27 and Figure 28, with the lower portion among the figure as " front end ", upper portion is described as " cardinal extremity ".

As Figure 27 and tube for transfusion assembly (infusion set) the 1st shown in Figure 28, inject the device (assembly) of (input) transfusion to organism (patient).

Transfusion for example comprises medicinal liquid, proofread and correct that all can drop into the liquid of organism with electrolyte solution, normal saline etc.

In addition, the kind of the medicament in the medicinal liquid is not particularly limited, and can be any medicaments such as tranquilizer, intravenous anesthetic, anesthesia class analgesic, local anesthetic, non depolarization muscle relaxant, pressor agent, depressor, coronary vasodilator, diuretic, antiarrhythmics, bronchodilator, hemorrhage, vitamin agent, antibiotic agent, lipomul for example.

As shown in figure 27, tube for transfusion assembly 1 possesses has: first tube for transfusion [the first pipe fitting assembly (pipe fitting assembly)] 4b; Second tube for transfusion [the second pipe fitting assembly (pipe fitting assembly)] 4a; The adapter 5A that can connect the end of the first tube for transfusion 4b and the second tube for transfusion 4a respectively; Be separately positioned on the bottle pin 451 (connecting portion) on another end of the first tube for transfusion 4b and the second tube for transfusion 4a; With the transfusion administration portion 2 that the patient is dropped into transfusion.Below, these each structural elements are described in order.

As Fig. 1～shown in Figure 3, adapter 5A has: outconnector portion (inserting shape adapter portion) 6; Female connector portion (being inserted into shape adapter portion) 7A and 7B; Outer sticking department (inserting the shape sticking department) 8A; Interior sticking department (being inserted into the shape sticking department) 9A and 9B; And valve body (seal member) 51.And Fig. 1～Fig. 3 represents that respectively adapter 5A is connected state, adapter 5A and adapter 5A ' half lock-out state, adapter 5A and adapter 5A ' lock-out state before with adapter 5A '.

At this, so-called " adapter 5A ' " has outconnector portion 6 identical with adapter 5A and the adapter of outer sticking department 8A.

In addition, so-called " half locking (temporary fixed) state " is adapter 5A and the state that adapter 5A ' is not connected fully, promptly can must make adapter 5A and the isolating state of adapter 5A ' easily.

In addition, so-called " lock-out state " state that to be adapter 5A (interior sticking department 9B) be connected fully with adapter 5A ' (interior sticking department 9A), promptly only otherwise the operating portion 93 of the interior sticking department 9B of adapter 5A described later is operated, be connected state between adapter 5A and the adapter 5A ' with regard to not being disengaged.

As shown in Figure 1, outconnector portion 6 has outconnector portion main body 61 and tube 62.

Tube 62 is outstanding to x axle positive direction from outconnector portion main body 61.This tube 62 has the fluid flowing path (inner cavity) 621 and the drain tapering 622 of liquid communication.

Liquid flow path 621 and outconnector portion 61 interior connections of main body.

The mode that drain tapering 622 reduces in the direction (x axle positive direction) towards peristome 623 gradually with its external diameter is formed on the peripheral part of peristome 623 sides of outconnector portion 6.

7A of female connector portion and 7B are respectively the positions that the outconnector portion 6 of adapter 5A ' can connect.Because the shape (structure) of 7A of female connector portion and the 7B of female connector portion is identical substantially, thus following be that representative describes with the 7B of female connector portion.

As shown in Figure 8, the 7B of female connector portion has female connector portion main body 72 and cap (lid) 73.

On female connector portion main body 72 as shown in Figure 8, be formed with the valve body that is shaped as bottom tube-like portion 721 is set.The base end side that portion 721 inside are set at this valve body is formed with second inner cavity (inner cavity) 723, and is formed with the 3rd inner cavity (inner cavity) 724 that is communicated with second inner cavity 723 in front.The internal diameter of second inner cavity 723 is than being formed at the big of first inner cavity (inner cavity) 731 on the lid 73 described later; The internal diameter of the 3rd inner cavity 724 (inner peripheral surface 728) is littler than second inner cavity 723.The internal diameter of preferred the 3rd inner cavity 724 is bigger than the maximum outside diameter of the trunk 55 (outer peripheral face 551) of valve body 51 described later.

In addition, valve body central part that the bottom surface 722 of portion 721 (female connector portion main body 72) is set is provided with the inner projection 725 that is made of tubular body.When outconnector portion 6 is connected with first inner cavity 731 (connector 732), when valve body 51 begins to be subjected to pushing, by the inside (inboard) of these inner projection 725 support valve bodies 51, (valve body 51 is converted into "＜" word shape) (with reference to Fig. 9) can prevent to buckle on valve body 51.In addition, can prevent the generation of liquid holdup in the time of in flow of liquid is crossed adapter 5A.

In addition, the inner chamber of this inner projection 725 is with stream 611 that form, that liquid can pass through is connected in the inside of outconnector portion main body 61.Thus, second inner cavity 723 and the 3rd inner cavity 724 are communicated with stream 611 by inner projection 725.

In addition, the front of the outer peripheral face 726 of portion 721 is set, is provided with the diameter stage portion 727 bigger than base end side diameter at valve body.

Cap 73 as shown in Figure 8 is that inside has the space (inner cavity) of taking in valve body 51, and with the valve body of female connector portion main body 72 parts that one 721 is connected is set.

In the inside of cap 73, be formed with first inner cavity 731 that can insert for the head 50 of valve body 51 described later, and be communicated with and compare the fitting portion 733 of first inner cavity, 731 enlarged-diameter with first inner cavity 731.

The corresponding mode of profile with the head 50 of the shape of first inner cavity 731 and valve body 51 forms first inner cavity 731.In addition, at the base end side of first inner cavity 731, be formed with the connector (connecting portion) 732 that is used to connect outconnector portion 6, the diameter of front that its diameter is compared first inner cavity 731 is little.

On the inner peripheral surface 734 of first inner cavity 731, equally spaced be provided with radially outstanding a plurality of ribs 735 to first inner cavity 731 along the circumferencial direction of inner peripheral surface 734.As outconnector portion 6 and adapter 5A (connector 732) when being connected, support valve bodies 51 by this rib 735, (valve body 51 overturnings) can prevent to buckle on valve body 51.In addition, the number of rib 735 is not particularly limited, and for example preferred 2～10, more preferably 4～8.

Be formed with the chimeric stage portion 736 of stage portion 727 that portion 721 is set with valve body in the front of fitting portion 733, its diameter is bigger than the diameter of the base end side of fitting portion 733.In addition, the internal diameter of preferred stage portion 736 and valve body external diameter that the stage portion 727 of portion 721 is set equates substantially or is smaller.Thus, cap 73 (stage portion 736) and female connector portion main body 72 (stage portion 727) chimeric securely (connection) (liquid thickly connects) therefore, can be able to be prevented the leak of liquid of adapter 5A inside.In addition, when cap 73 and 72 bindings of female connector portion main body, first inner cavity 731 and second inner cavity 723 are communicated with, and (taking in) valve body 51 can be set in by first inner cavity 731, second inner cavity 723 and the 3rd inner cavity 724 formed spaces.

And, be not limited to chimericly as the fixing means of female connector portion main body 72 and cap 73, for example can be riveted joint, utilize bonding etc. bonding etc. of bonding, heat bonding, the ultrasound wave of binding agent

Shown in Fig. 1 (Fig. 2 and Fig. 3 are too), the 7A of female connector portion is set on the x axle negative direction with respect to outconnector portion main body 61.That is, the peristome 623 of the peristome 71 of and female connector portion 7A parallel with the centrage of outconnector portion 6 and outconnector portion 6 with the centrage of the 7A of female connector portion mutually in the opposite direction modes dispose the 7A of female connector portion.

Thus, for example, when connecting two adapters 5, a side outconnector portion 6 and the opposing party's the 7A of adapter portion are connected, just can point-blank two adapters 5 be connected with each other substantially.

The 7B of female connector portion is set on the z axle positive direction with respect to outconnector portion main body 61 (outconnector portion 6) to be had.That is, the 7B of female connector portion is set with the centrage of the 7B of female connector portion and the orthogonal mode of centrage cardinal principle of outconnector portion 6.

By such 7A of female connector portion and 7B are set, can either liquid be carried to outconnector portion 6 from two different directions, can make liquid from outconnector portion 6 to two different directions branches again.

In addition, when for example having connected the outconnector portion 6 of adapter 5A ' on the 7B of female connector portion, the drain tapering 622 of adapter 5A ' is fitted to the edge portion (inner circumference portion) of the connector 732 of the 7B of female connector portion reliably.That is, liquid thickly connects the outconnector portion 6 (with reference to Fig. 9) of adapter 5A ' on the 7B of female connector portion.

As Fig. 8 and shown in Figure 9, in the 7A of female connector portion and take in (fixing) respectively in the 7B of female connector portion valve body 51 is arranged.

Each valve body 51 is made of elastomeric material.As this elastomeric material, can enumerate for example natural rubber, isoprene rubber, butadiene rubber, SBR styrene butadiene rubbers, acrylonitrile-butadiene rubber, chloroprene rubber, butyl rubber, acrylic rubber, ethylene-propylene rubber, chlorohydrin rubber, urethane rubber, silicone rubber, the various elastomeric materials that fluorubber is such, phenylethylene, TPO, polyvinyl chloride, polyurethanes, polyesters, polyamide-based, polybutadiene, the using trans-polyisoprene class, fluorine class rubber-like, the various thermoplastic elastomer (TPE)s of chlorinated polyethylene class etc. can use wherein a kind of or are use mixing two or more.By using such elastomeric material, can on the end face 511 of valve body 51, obtain the elasticity of appropriateness, therefore, end face 511 can be adjacent to the peristome (end face) 623 (with reference to Fig. 9) of outconnector portion 6.

As shown in Figure 7, valve body 51 has head 50 and (formation) trunk 55 on the front of head 50 is set.

As shown in Figure 8, be formed with in the head 50: shape is inner cavity 515 bottom tube-like, that liquid is passed through; With slit 512 from plane end face 511 (bottom 513) to inner cavity 515.The shape in this slit 512 is " one " word shape substantially.By making slit 512 become so simple shape, can be more prone to (reliably) with slit 512 openings (opening).In addition, because end face 511 is plane, so can easily carry out disinfection to end face 511 (slit 512).

As shown in Figure 1, end face 511 exposes from the peristome 71 of the 7B of female connector portion.In addition, this end face 511 is positioned on the same plane substantially with the end face of the 7B of female connector portion.

Head 50 has: near the external diameter its end face 511 is towards tapered tapering 56 that trunk 55 (towards z axle negative direction) increases gradually; With constant 57 of the external diameter that is arranged on its front end.

In addition, be formed with on the tapering 56 notch (cutting damage portion) 561 after the part excision in tapering 56.That is, on head 50, be formed with the notch 561 that excises in the mode that strides across constant 57 of tapering 56 and external diameter.

Thus, when (insertion) the outconnector portion 6 on adapter 5A that will connect extracted, when promptly unlocking state, valve body 51 (head 50) can enter first inner cavity 731 of cap 73 more easily, therefore, can close slit 512 more reliably.

In addition, head 50 has two that be pressed, outstanding abutting parts 52 when closing slit 512.These two abutting parts 52 are respectively formed near the end face 511 of head 50, and are outstanding to the direction opposite with the direction of closing slit 512 (direction of arrow among Fig. 7).

By such abutting part 52, when head 50 is inserted in first inner cavity 731 of cap 73, because the inner peripheral surface of first inner cavity 731 734 pushing abutting parts 52, so can close slit 512 (with reference to Fig. 8) more reliably.In addition, thus, can improve the resistance to pressure of valve body 51 (slit 512) for the pressure (intrinsic pressure) of the liquid in the adapter 5A.

The head 50 of Gou Chenging is when connecting outconnector portion 6 as mentioned above, is inserted under 512 closing state of slit in first inner cavity 731 of cap 73 (with reference to Fig. 8).

As shown in Figure 7, trunk 55 is made of the cylindrical body that is accordion-like.That is, trunk 55 presents the accordion-like that big footpath ring portion 552 and path ring portion 553 are alternately arranged in the axial direction in shape.Such trunk 55 is as valve body 51 is played a role to the variant part (augmentor) that base end part (head 50 being inserted the direction of first inner cavity 731 of cap 73) suppresses from its front.

Because such trunk 55 plays a role as variant part, thus there is no need in adapter 5A, to be provided for constituting the parts that suppress device in addition, thus help the minimizing of part count, the simplification of structure.

In addition, this trunk 55 born make valve body 51 from its front towards the restorative most of recuperability of base end side, head 50 also can be born the part of this recuperability.

In addition, on trunk 55 (cylindrical portion), the number of the locational protuberance of its accordion-like (big footpath ring portion 552) is three or four.That is, the number of the locational recess of its accordion-like (path ring portion 553) is four or five.

In addition, slit 512 is the pushing by outconnector portion 6 and parts of opening in structure as shown in Figure 9, but be not limited to this, for example can be by the running through and the parts of opening of outconnector portion 6, also can be pin by being arranged on (in the 7B of female connector portion) in the valve body 51 or running through of contact pin and the parts of opening.

As shown in Figure 1, outer sticking department 8A has: base portion (outer sticking department main body) 81; From the outstanding protuberance 82 of base portion 81; Be arranged on a pair of claw 83A, 83A on the protuberance 82; With the elastic pressing part 84 that each claw 83A is suppressed.

The shape of base portion 81 is elongate.

On the y axle positive direction of base portion 81 (outer sticking department 8A), the outconnector portion main body 61 of outconnector portion 6 is arranged in abutting connection with base portion 81 bonding (fixing).In addition, on the x of base portion 81 axle positive direction, be formed with to the outstanding protuberance 82 of this direction.

On the z of protuberance 82 direction of principal axis (above-below direction among Fig. 1), be respectively arranged with claw 83A and 83A.Two claw 83A, 83A end 831 separately is approaching on the z direction of principal axis mutually/away from.

The end 831 of each claw 83A is provided with as the holding section, first outside 832 with a part of otch (cutting damage) of this end 831.

In addition, on axial two sides, be respectively arranged with the holding section, second outside 833 of concavity towards y at each claw 83A.

The degree of depth of holding section, second outside 833 is not particularly limited, but preference is as 0.05～0.6mm, more preferably 0.1～0.4mm.

Elastic pressing part 84 is set between protuberance 82 and the claw 83A.This elastic pressing part 84 with two claw 83A, 83A end 831 (holding section, first outside 832) separately mutually away from mode each claw 83A is suppressed.

The outer sticking department 8A of Gou Chenging is positioned on the position with outconnector portion 6 corresponding (adjacency) (with reference to Fig. 1) like this.In addition, outer sticking department 8A and outconnector portion 6 form along the x direction of principal axis respectively, and promptly closure (projected direction) is parallel to each other.

As shown in Figure 1, interior sticking department 9A and 9B are respectively the positions that can connect the outer sticking department 8A of adapter 5A '.

Interior sticking department 9A is arranged on the x axle negative direction with respect to base portion 81 (outer sticking department 8A).In addition, interior sticking department 9B is arranged on the z axle positive direction with respect to base portion 81 (outer sticking department 8A).Because the shape of interior sticking department 9A and interior sticking department 9B is identical substantially, so sticking department 9B in the following explanation typically.

The global shape of interior sticking department 9B is rendered as tubulose substantially.

As Fig. 4 and shown in Figure 6, interior sticking department 9B is provided with: the first inboard holding section 91 that can engage with each holding section, first outside 832 of the outer sticking department 8A of adapter 5A '; The second inboard holding section 92 that can engage with the holding section, second outside 833 of the outer sticking department 8A of adapter 5A '; With the operating portion 93 that can operate each claw 83A of the outer sticking department 8A of adapter 5A '.

As shown in Figure 4, the first inboard holding section 91 forms towards the mode that z axle negative direction (among Fig. 4, left to) reduces gradually with the size of the inner circumference portion of peristome 94 sides of interior sticking department 9B.Shown in Fig. 4 (c), the end 911 by the first inboard holding section 91 fastens with the holding section, first outside 832 of the outer sticking department 8A of adapter 5A ', forms the state that adapter 5A (interior sticking department 9B) and adapter 5A ' (outer sticking department 8A) lock.

As shown in Figure 6, it is outstanding on the inner circumference portion of sticking department 9B in the second inboard holding section 92 is arranged in.Shown in Fig. 6 (b), fasten by the holding section, second outside 832 of the second inboard holding section 92 with the outer sticking department 8A of adapter 5A ', form the state of adapter 5A and adapter 5A ' locking.

As shown in Figure 5, operating portion 93 is relative with the first inboard holding section 91, and is made of the small pieces that are arranged on the z direction of principal axis.93 couples of each claw 83A of this operating portion operate (pushing), make that the end 831 of two claw 83A of adapter 5A ' (outer sticking department 8A) of lock-out state is approaching mutually.

In addition, operating portion 93 forms in the mode that the outer surface of its outer surface and the first inboard holding section 91 is positioned on same substantially.Thus, can prevent from inadvertently to touch (pushing) operating portion 93.That is, can prevent the state that inadvertently unlocks.

The interior sticking department 9B of Gou Chenging is positioned on the position with the 7B of female connector portion corresponding (adjacency) (with reference to Fig. 1) like this.In addition, interior sticking department 9B and the 7B of female connector portion form along the z direction of principal axis respectively.Be that closure (formation direction) is parallel to each other.

Like this, in adapter 5A, outer outer between (outer sticking department 8A and outconnector portion 6), interior between (interior sticking department 9B and the 7B of female connector portion) distinguish corresponding.Thus,, adapter 5A and adapter 5A ' can be correctly connected (reliably), by sticking department 9B and outer sticking department 8A in confirming, adapter 5A and adapter 5A ' can be correctly connected in addition (reliably) by confirming female connector 7B of portion and outconnector portion 6.

And the formation number of holding section, second outside 833 is not limited to four, for example also can be even numbers such as two, six.

In addition, the degree of depth that fastens of second inboard holding section 92 under half lock-out state and holding section, second outside 833 is not particularly limited for example preferred 0.02～0.5mm, more preferably 0.15～0.35mm.Thus, can suitably set the power that engages of the second inboard holding section 92 and holding section, second outside 833.

In addition, constituent material as the position except valve body 51 of adapter 5A is not particularly limited, can enumerate polyethylene, polypropylene, the polyolefin of polybutadiene etc., polyurethane, polystyrene, the acrylic resin of polymethyl methacrylate etc., Merlon, polyamide, the polyester of polyethylene terephthalate etc., ABS resin, the AS resin, the various resin materials of the fluorine-type resin of ionomer etc. etc., polyurethanes, polyesters, polyamide-based, olefines, the various thermoplastic elastomer (TPE)s of phenylethylene etc., rustless steel, aluminum, the various metal materials of titanium etc., various glass materials etc. can use separately or combination (for example as composite) is at random used.

Next, the connection procedure (half lock-out state, lock-out state) to adapter 5A and adapter 5A ' describes.

Shown in Fig. 1 (Fig. 6 (a)), from adapter 5A and adapter 5A ' mutually away from state, make the outer sticking department 8A of adapter device 5A ' approaching to the interior sticking department 9B of adapter 5A.

Shown in Fig. 4 (a), along with the outer sticking department 8A with adapter 5A ' inserts in the interior sticking department 9B of adapter 5A, the elastic force pressure of the elastic pressing part 84 of the first inboard holding section 91 opposing adapter 5A ' of adapter 5A, and the claw 83A of pushing adapter 5A '.

Shown in Fig. 4 (b), further the outer sticking department 8A with adapter 5A ' inserts in the interior sticking department 9B of adapter 5A, shown in Fig. 6 (b), the holding section, second outside 833 of adapter 5A ' fastens with the second inboard holding section 92 of adapter 5A, that is, adapter 5A ' and adapter 5A are in half lock-out state.At this moment, the outconnector portion 6 of adapter 5A ' (peristome 623) is in contact with one another (approaching) (with reference to figure 2) with the 7B of female connector portion (end face 511) of adapter 5A.Thus, when make its from half lock-out state when lock-out state changes, the end face of the outconnector portion 6 of adapter 5A ' (peristome 623) can promptly push the end face 511 of the valve body 51 of adapter 5A reliably.

If further the outer sticking department 8A with adapter 5A ' inserts in the interior sticking department 9B of adapter 5A, then unclamp with second the engaging of inboard holding section 92 of adapter 5A the holding section, second outside 833 of adapter 5A ', and promptly half lock-out state is disengaged.

If the outer sticking department 8A of adapter 5A ' and the interior sticking department 9B of adapter 5A are close from this state, then the holding section, first outside 832 of adapter 5A ' engages with the first inboard holding section 91 of adapter 5A, that is, adapter 5A ' and adapter 5A become lock-out state (with reference to Fig. 4 (c)).Like this, adapter 5A ' and adapter 5A can easily become lock-out state from half lock-out state.

And when being in half lock-out state, the outer sticking department 8A of adapter 5A ' and the valve body 51 of adapter 5A are approaching mutually, and in this case, they also can be adjacent to mutually.

As shown in Figure 9, when being in the lock state, the peristome 623 of the outconnector portion 6 of adapter 5A ' is pushing the end face 511 of the head 50 of adapter 5A in the axial direction.Thus, trunk 55 is out of shape (being compressed) in the axial direction, and head 50 moves into second inner cavity 723 since first inner cavity 731.Head 50 is limited by the inner peripheral surface 734 of first inner cavity 731 in first inner cavity 731 before this, but by moving to second inner cavity 723, the restriction of the outer circumference surface of head 50 is disengaged or relaxes, consequently, by axial compression, hole enlargement on the direction of arrow in Fig. 9 fully promptly, can be out of shape fully.Therefore, can be reliably and make slit 512 open (opening) fully.In addition, thus, by valve body 51 (slit 512), the liquid flow path 621 of the outconnector portion 6 of adapter 5A ' is communicated with the inner cavity (hollow bulb) of the inner projection 725 of the 7B of female connector portion of adapter 5A, that is, connects in negotiable mode, therefore, for example, when infuse, blood transfusion, nutrition input etc. the time, liquid can pass through swimmingly.

In addition, when lock-out state, because resist mutually with the elastic force pressure of the trunk 55 of valve body 51, the head 50 of the peristome 623 pushing valve bodies 51 of the outconnector portion 6 of adapter 5A ' is so the end face 511 of the peristome 623 of this outconnector portion 6 and head 50 (valve body 51) is adjacent to.Thus, can keep outconnector portion 6 and the close property of the liquid that is connected of the 7B of female connector portion, that is, liquid thickly connects them reliably.

In addition, adapter 5A ' is to implement by the operating portion 93 that is operatively connected device 5A with the releasing of the lock-out state of adapter 5A.

In other words, from the lock-out state shown in Fig. 5 (a), the claw 83A that pushes adapter 5A ' like that by the operating portion 93 of adapter 5A shown in Fig. 5 (b).Thus, engaging between first of the adapter 5A inboard holding section 91 and the holding section, first outside 832 that meets device 5A ' unclamps (being disengaged).At this moment, the head 50 of valve body 51 moves to first inner cavity 731 by the recuperability of trunk 55, closes slit 512 as described above.Thus, the circulation of the liquid between adapter 5A and the adapter 5A ' is blocked, and therefore, can prevent reliably that liquid from sewing from for example adapter 5A.

Afterwards, shown in Fig. 5 (c), if pull adapter 5A ', then adapter 5A ' and adapter 5A mutually away from.

And when above-mentioned engaging was unclamped, under the less situation of the inlay resultant force of the outconnector portion 6 of the 7B of female connector portion of adapter 5A and adapter 5A ', by the elastic force pressure of valve body 51, adapter 5A ' broke away to go up the mode of being upspring from adapter 5A.That is, adapter 5A ' is broken away from from adapter 5A.

In addition, when breaking away from, can be with the elastic force pressure (elastic force) of the elastic pressing part 84 of adapter 5A ' as resilience force use for the inner peripheral surface of the first inboard holding section 91 of the adapter 5A of claw 83A.

In addition, can break away from from adapter 5A in the mode of upspringing by adapter 5A ' like this, for example under adapter 5A ' and situation about fluffing being connected of adapter 5A, adapter 5A ' is upspring from adapter 5A.Thus, can confirm whether adapter 5A ' and adapter 5A are in the lock state.

In addition, under the bigger situation of above-mentioned inlay resultant force, because do not break away from, so can prevent from or suppress to flow through the interior liquid (for example, being good liquid such as anticarcinogen) of adapter 5A to disperse to periphery (outside) not disperse to periphery in the mode of upspringing.

Like this, be pressed into shirtsleeve operation like this in the interior sticking department 9B of adapter 5A by the outer sticking department 8A with adapter 5A ', adapter 5A can be connected fully with adapter 5A ', that is, adapter 5A and adapter 5A ' can become lock-out state reliably.

In addition, substantially with become lock-out state the 7B of female connector portion thickly be connected with outconnector portion 6 liquid of adapter 5A '.

In addition, under half lock-out state, suppress the distortion of (preventing) valve body 51.For example, be the tube for transfusion assembly 1 of half lock-out state when dispatching from the factory at adapter 5A and adapter 5A ', can prevent that long-time distortion does not take place valve body 51 before this tube for transfusion assembly 1 is used.Thus, can prevent that valve body 51 from plastic deformation taking place, and prevents that slit 512 is in the state of often opening.

In addition, in illustrated structure, when lock-out state, the drain tapering 622 of the outconnector portion 6 of adapter 5A ' and the inner circumference portion chimeric (being adjacent to) of the connector 732 of the 7B of female connector portion of adapter 5A, but be not limited to this, they can be not chimeric yet,, can form the gap between them that is yet.And, when the drain tapering 622 of the outconnector portion 6 of adapter 5A ' was chimeric with the inner circumference portion of the connector 732 of the 7B of female connector portion of adapter 5A, the 7B of the female connector portion quilt of the outconnector portion 6 of adapter 5A ' and adapter 5A more liquid feeding thickly was connected.

In addition, adapter 5A is made of an outconnector portion 6, two 7A of female connector portion and 7B, outer sticking department 8A and two interior sticking department 9A and 9B, but be not limited to this, for example can also constitute by an outconnector portion 6, outer sticking department 8A or an interior sticking department 9A (interior sticking department 9B is too), can also be by a 7A of female connector portion (interior sticking department 7B is too), outer sticking department 8A or an interior sticking department 9A (interior sticking department 9B is too) formation.

As shown in figure 27, transfusion administration portion 2 has: be retained in remaining needle or conduit (being remaining needle 21 in the present embodiment) in patient's the blood vessel 110; With the transfusion administration portion side-connector 26 on the base end part that is connected this remaining needle or conduit (being remaining needle 21 in the present embodiment).

As the constituent material of remaining needle 21 (or conduit), according to the position of keeping somewhere, can be metal needles such as band wing intravenous needle, preferably have flexible macromolecular material, can enumerate for example polyene of polyethylene, polypropylene etc.; Polyester; The thermoplastic resin of polyurethane etc. etc.

Transfusion administration portion side-connector 26 has: interior sticking department 9A and the 7A of female connector portion are connected with outer sticking department 8A and the outconnector portion 6 of the adapter 5A that is connected with the second tube for transfusion 4a respectively; Interior sticking department 9B identical and the 7B of female connector portion with them; With outconnector portion 263.

In addition, the axle of outconnector portion 263 and the axle of the 7A of female connector portion are unanimous on the whole, the axle of the 7B of female connector portion and these cardinal principle quadratures.That is, outconnector portion 263 and the 7A of female connector portion are towards mutually opposite direction, and the 7B of female connector portion is towards the direction of cardinal principle perpendicular to these outconnector portions 263 and the 7A of female connector portion.

In the transfusion administration portion side-connector 26, liquid thickly is connected with pipe fitting 24 in outconnector portion 263, and this pipe fitting 24 passes with what simple operations just can make that it stops and stops anchor clamps 25.Front at pipe fitting 24 is connected with outconnector portion 23.Outconnector 23 can be formula adapter in distress, formula lock connector in distress etc., so long as can with close the getting final product of being connected of outlet port 211 liquid of remaining needle or conduit, be not particularly limited, but preferred formula lock connector in distress arranged.

The base end part of remaining needle 21 has outlet port 211, thickly is connected with the outconnector portion 23 that is installed on the above-mentioned transfusion administration portion side-connector 26 at liquid on this outlet port 211.

Next, the first transfusion pipe fitting 4b and the second transfusion pipe fitting 4a are described, because the structure of these the first transfusion pipe fitting 4b and the second transfusion pipe fitting 4a is identical, so the second transfusion pipe fitting 4a is described typically.

The second transfusion pipe fitting 4a possesses and has: have pipe fitting 41 flexible (flexibility), that constitute the stream of transfusion; Be arranged on the adapter 43 on the end (leading section) of pipe fitting 41; With bottle pin 451 with sharp keen needle point, be arranged on the other end (being the other end (base end part)) of pipe fitting 41 in this example, and as the connecting portion that is connected with transfusion bag (infusion vessel) (taking in side) 31 sides of taking in transfusion.

Can enumerate for example soft PVC, vinyl acetate copolymer, polyethylene, polypropylene, polybutadiene etc. or based on these material as the constituent material of pipe fitting 41.

In addition, be respectively arranged with slidingtype clip (slide clamp) 46 and drop tube 44 as the flow control device of adjusting infusion flow midway at pipe fitting 41.Be not particularly limited as this slidingtype clip 46, can use existing known slide clamp, can enumerate for example special slide clamp such in the 2004-49319 communique of opening.

In addition, slidingtype clip 46 so long as roller type clip etc. can be regulated getting final product of flow, and other clip also can.

In transfusion bag 31, take in the transfusion of regulation, when bottle pin 451 runs through the stopper (rubbery stopper) of (piercing through) this transfusion bag 31, by bottle pin 451, transfusion bag 31 is connected with the second transfusion pipe fitting 4a, thereby becomes state from transfusion bag 31 to the second transfusion pipe fitting 4a side that can supply with transfusion from.

Drop tube 44 be arranged on bottle pin 451 near.Can with the naked eye confirm the flow of infusing by this drop tube 44.

In addition, between adapter 43 and drop tube 44, be provided with check valve 49.Check valve 49 is from transfusion bag 31 check valves to adapter 5A.Check valve 49 is so long as between adapter 43 and drop tube 44, is arranged on passablely everywhere, preferably is arranged on the position near adapter 43, more preferably is arranged on the inside of adapter 43.

Have the valve body that the switch block by not shown pair of plate-shaped forms in the inside of check valve 49, each switch block is adjacent to mutually by elastic force (recuperability), thus, and the stream obturation in the check valve 49.Transfusion stream from front under the situation of base end side because this infusion pressure acts on the outside of each switch block, playing a role makes and is adjacent between the switch block.Therefore, transfusion can not flow to base end side from front.

On the other hand, transfusion stream from base end side under the situation of front, the pressure of this transfusion regulation acts on the base end side (conical surface) of each switch block, because of this pressure make each switch block to away from the direction displacement, then the interior stream of check valve 49 is open-minded.Thus, transfusion flows to front from base end side.

Though check valve 49 also can be set utilizing infusion pump etc. to make to inject under the reliable situation that becomes, more preferably be provided with check valve 49.Even if the pressure to a certain degree of the first transfusion pipe fitting 4b that will be connected from the adapter 5A with the second transfusion pipe fitting 4a is applied to the second transfusion pipe fitting 4a and carries out the administration transfusion, can prevent also that by check valve 49 this transfusion from flowing into the upstream side (base end side) of the second pipe fitting 4a, thereby can supply with transfusion to the patient reliably.

Leading section at pipe fitting 41 is provided with adapter 43.This adapter 43 has outconnector portion 6 and outer sticking department 8A.Thus, adapter 43 can be connected with adapter 5A.

Like this, because at least one parts that adapter 5A, adapter 43 and transfusion administration portion side-connector 26 are provided with among outconnector 8A and interior sticking department 9A, the 9B, so when interconnection these adapters, compare with the situation that existing formula in distress locks such revolving type, can prevent that locked such situation occurs under twisting states.That is, by using such method of attachment, under a plurality of continuous situations of transfusion pipe fitting, the pipe fitting that also can keep simply infusing is arranged in the state on the constant direction.

In addition, for example when being connected of the interior sticking department 9B of the outer sticking department 8A that has finished adapter 43 and adapter 5A (in the lock-out state), can hear " click is rattled away " such Click (confirm connect sound).Thus, with do not know that tightening to the revolving type parts that where could lock compares, and can confirm locked by sound more reliably.Below, in the mutual connection of adapter, outer sticking department 8A of explanation and interior sticking department 9B's is connected typically.

In addition, because as formula adapter in distress by rubbing of rake (tapering) under the incompatible situation of carrying out chimeric parts, distance between the adapter after it is chimeric is not constant, so the outer sticking department 8A and the dimensional accuracy between the interior sticking department 9B that be arranged in parallel must be very tight, but because adapter 5A has valve body 51 described later, the elasticity by valve body 51 allows the range deviation between the adapter easily.Therefore, still keep the close state of liquid, even if dimensional accuracy and imprecision also can be realized reliable locking (connection).

In addition, for example also have under the connection status of the interior sticking department 9B of the outer sticking department 8A of adapter 43 and adapter 5A, as described above, just can access half lock-out state and lock-out state.

For example, before using the second transfusion pipe fitting 4a, the outconnector portion 6 of adapter 43 loosely is entrenched on the position that does not make the degree that the valve body 51 on the 7B of female connector portion that is arranged on adapter 5A opens.That is, before using the second transfusion pipe fitting 4a, adapter 43 is connected with half lock-out state with adapter 5A.Thus, before transfusion was about to flow, valve body 51 did not have the shifting ground to be held, and can fully nondestructively use the function of valve body.

In addition, under lock-out state, because the 7B of the female connector portion liquid of the outconnector portion 6 of adapter 43 and adapter 5A thickly is connected, so liquid is circulated to adapter 5A from the second transfusion pipe fitting 4a reliably.

Next, the effect (using method) to transfusion pipe fitting assembly 1 describes.

At this, infuse pipe fitting 4a as first tube for transfusion (the first transfusion path) that is used for dropping into to the patient transfusion with second, promptly mainly be to use as the transfusion pipe fitting that basic liquid etc. flows through, infuse pipe fitting 4b as second tube for transfusion (the second transfusion path) that is used for dropping into to the patient transfusion with first, promptly mainly be to use, for example can example enumerate describing as the situation that flows through the transfusion pipe fitting of lipomul, curative, antibiotic agent etc. as secondary path.

When connecting the second transfusion pipe fitting 4a, at first, infusion solution is kept in preparation in transfusion bag 31.

Next, the 7B of female connector portion with the outconnector portion 6 of adapter 43 is pressed into adapter 5A makes their liquid thickly chimeric.

Next, as shown in figure 27, the bottle pin 451 of the second transfusion pipe fitting 4a runs through the stopper (rubbery stopper) that (piercing through) takes in the transfusion bag 31 of this transfusion.Thus, connect transfusion the bag 31 and second transfusion pipe fitting 4a, become state from transfusion bag 31 to the second transfusion pipe fitting 4a side that to supply with transfusion from by bottle pin 451.

Next, the stream of the starting second transfusion pipe fitting 4a.

Next, with the blood vessel that is retained in the patient (for example, tip veins etc.) in the 7A of female connector portion of the transfusion administration portion side-connector 26 that is connected of the outlet port 211 of the remaining needle 21 in 110, the outconnector portion 6 that inserts the adapter 5A of the second transfusion pipe fitting 4a makes them chimeric.Thus, the 7A of female connector portion of transfusion administration portion side-connector 26 thickly is connected with outconnector portion 6 liquid of the adapter 5A of the second transfusion pipe fitting 4a.At this moment, the interior sticking department 9A of transfusion administration portion side-connector 26 and the outer sticking department 8A of adapter 5A become lock-out state, can prevent to connect and easily be removed.

Next, the slidingtype clip 46 of the operation second transfusion pipe fitting 4a is adjusted to the indication flow (indication injection speed) of keeping infusion solution with the flow (injection speed) of the transfusion of the second transfusion pipe fitting 4a, supplies with this transfusion.

And, can also omit transfusion administration portion side-connector 26, the outconnector portion 6 of the adapter 5A of the second transfusion pipe fitting 4a is connected with the outlet port 211 of remaining needle 21.

Next, connect when dropping into the first transfusion pipe fitting 4b that antibiotic for example uses according to patient's situation interval at regular intervals, at first, the normal saline of antibiotic agent has been dissolved in preparation in transfusion bag 32.

Next, the 7B of female connector portion with the outconnector portion 6 of the adapter 43 of the first transfusion pipe fitting 4b is pressed into adapter 5A makes their liquid thickly chimeric.

Next, the bottle pin 451 of the first transfusion pipe fitting 4b runs through the stopper (rubbery stopper) that (piercing through) takes in the transfusion bag 32 of this transfusion.Thus, connect transfusion the bag 32 and first transfusion pipe fitting 4b, become state from transfusion bag 32 to the first transfusion pipe fitting 4b side that to supply with transfusion from by bottle pin 451.

Next, the stream of the starting first transfusion pipe fitting 4b.

Next, as Figure 28 and shown in Figure 29, in the 7A of female connector portion of the adapter 5A of the second transfusion pipe fitting 4a, the outconnector portion 6 that inserts the adapter 5A of the first transfusion pipe fitting 4b makes them chimeric.Thus, the 7A of female connector portion of the adapter 5A of the second transfusion pipe fitting 4a thickly is connected with outconnector portion 6 liquid of the adapter 5A of the first transfusion pipe fitting 4b.At this moment, the outer sticking department 8A of the interior sticking department 9A of the second transfusion pipe fitting 4a and the first transfusion pipe fitting 4b becomes lock-out state, can prevent to connect and easily be removed (with reference to Figure 29).

Next, the slidingtype clip 46 of the operation first transfusion pipe fitting 4b is adjusted to the indication flow (indication injection speed) of antibiotic agent with the flow (injection speed) of the transfusion of the first transfusion pipe fitting 4b, supplies with this transfusion.

So, can supply with to the patient from the second transfusion pipe fitting 4a respectively and keep infusion solution, supply with the normal saline (can mix injection) that has dissolved antibiotic agent to the patient from the first transfusion pipe fitting 4b.

In addition, under the situation of setting up tube for transfusion (transfusion path), ground same as described above, in the 7A of female connector portion of the adapter 5A of the first transfusion pipe fitting 4b, the outconnector portion 6 that inserts the adapter 5A of other not shown pipe fittings of infusing makes them chimeric.Thus, the 7A of female connector portion of the adapter 5A of the first transfusion pipe fitting 4b thickly is connected with outconnector portion 6 liquid of the adapter 5A of other transfusion pipe fittings.

Below, similarly, can also set up a plurality of tube for transfusions.

And the using method of above-mentioned transfusion pipe fitting assembly 1 is an example, is not limited to this.

For example, infusing from the second transfusion pipe fitting 4a when the patient supplies with, can also carry out replenishing by the first transfusion pipe fitting 4b to it.

As described above, according to this transfusion pipe fitting assembly 1, because there is the connection port (7A of female connector portion, 7B and outconnector portion 6) of transfusion pipe fitting usually, so can set up tube for transfusion (transfusion path) easily, rapidly and reliably.

That is, because usually there is the connection port of transfusion pipe fitting, so the insufficient situation in connectivity port of the pipe fitting of infusing such as prevent when for example patient's situation sharply changes.
