Figure 13 A is for tiltedly watching the outward appearance perspective view of the state before the clip filling mechanism that special clip 1, universal clip 101 are filled in from the front, Figure 13 B is an outward appearance perspective view of tiltedly watching the clip filling mechanism after the filling from the front.
In this figure, adopt identical symbol for the component parts that has illustrated, omit explanation.Ways 54 in the openings lead portion that becomes a side forms opening slot part 54a as shown in the figure like that, and this opening slot part 54a forms shape and the inside dimension consistent with the reinforcement guide part 30 of the main base portion that is integrally formed in clip 1 or 101.In addition, form central slot part 54b in the central authorities of this opening slot part 54a, after main base portion slipped into, the 1st restriction portion 25 that extends portion 22 that is formed at was by the surperficial 54f of ways 54 restriction site like that as shown in the figure, and circular can not further be pressed into.
In addition, form the outer peripheral face be connected to the 2nd elastic supporting part 40 or protuberance that can sliding-contact on the outer peripheral face of the 2nd elastic supporting part 40 on the revoliving arm member 53, the joint degree sense when inserting to obtain clip.Lower component 56 and ways 54 uses the resin by same color to carry out the parts that resin forming obtains, and is fixed on the movable tube for transfusion occlusion piece 51 that constitutes the inaccessible mechanism of tube for transfusion and the fixing below of tube for transfusion occlusion piece 52 as shown in the figure like that.
Figure 14 becomes behind the blocked state from tiltedly watching the outward appearance perspective view of the state that fills in infusion set 200 tube for transfusion 2 or 3 for using special clip 1, universal clip 101.In addition, Figure 15 is a lateral operating instruction 57 of being located at infusion set 200.
In two figure, adopt identical symbol for the component parts that has illustrated, omit explanation.Clip 1 or 101 is thrown off from the outlet of drop tube 6, moves to the below of tube for transfusion 2 or 3, is arranged to blocked state.
Open the door 204 of infusion set 200, while watch the description 57 of Figure 15 to be provided with.Promptly, open door 204, remove the inaccessible mechanism of pipe, tube for transfusion 2 or 3 is set in the groove that is coloured to red pipe ways 268 of slot part 203m and the below of transfusion mechanism 201, make and insert guide part and be in ground, the place ahead and in clip 1 or 101 any is inserted into clip loads between unitary ways 54 and the revoliving arm member 53, enter into the depths.Then, when with the operation of pole shutoff 207 door 204 being fixed in main body, the unblocking state becomes disarm state, and what transfusion began is ready to complete.
As described above, when clip 1 or 101 falls under blocked state, can blocked state be removed by impulsive force, and, clip is movable to state shown in Fig. 2 A in a flash from the state of Fig. 2 B after closing door 204, unblocking, so each junction surface can not returned owing to permanent deformation.That is, be altered to, correspondingly form the anti-free-flow mechanism of the clip filling mechanism of door linkage type when closing door 204, the clip of shape of the permanent deformation of clip not taking place during unblocking.In addition, considered separately using of special-purpose infusion set and general infusion set, so, can use special-purpose infusion set and general infusion set both sides, testing result is shown in operation panel.
In addition, the occasion of special-purpose infusion set in transfusion accuracy guarantee 10%, can directly be installed on infusion pump uses, but in the occasion of using general infusion set, owing to can not guarantee to manage precision, so, also can use the drop cylinder sensor 47 of counting device as the optical profile type stalagmometer for example to detect as 1ml by 15,20,60, be arranged on the infusion set change-over switch that the state of having set a number uses down.In the occasion that user carries out the setting of this number from mount board, undertaken by automatic detection the such as IC labelling, bar code.
In addition owing to be provided with the anti-reinforcement guide part 30 of inserting the wall portion that prevents usefulness as clip 1 or 101, so, can prevent to misplug into.In addition, owing to become the stage portion restriction portion 25 of the clue when clip is arranged at clip filling unit clip being provided with, so, become the cardinal principle benchmark when being provided with.But the joint degree sense when being provided with obtains when crossing the protuberance of revoliving arm member.In addition, when dismounting, control clip and pipe simultaneously as the nurse, then manage warpage, the inaccessible releasing may leak, but this also prevented by jut.In addition, because clip 1 or 101 is packaged in the both sides of special-purpose infusion set and general infusion set simultaneously, and clip formed the type of using up of anti-mounting or dismounting shape, thus the eshaustibility clip.Like this, can prevent the refluence of the occasion of reciprocal filling.In addition, because (white, orange) is represented in the color separation of the clip of special-purpose infusion set of formation power and general infusion set, so, can discern simply.
Below, with reference to the three-dimensional exploded view of watching the clip filling mechanism of Figure 16 from lower side, the ground plan that the clip filling mechanism before 101 fillings of special clip 1 or universal clip schematically is shown of Figure 17 A, Figure 17 B schematically illustrate with special clip 1 fill in state behind the clip filling mechanism ground plan, and the ground plan that the state behind the clip filling mechanism that universal clip 101 is filled in schematically is shown of Figure 17 C, the clip filling mechanism is described.
The function of this clip filling mechanism can list the 1st function and the 2nd function; In the 1st function, be fixed to reference to the sliding contact surface 53f of the dip member 50 of the interior side-lower of the door 204 of the infusion set 200 of Figure 11 B explanation on-off action by door 204 by the 1st inclined plane 50c pushing revoliving arm member 53 of dip member 50, simultaneously, push the side of the pushing face 41a of clip 1 or 101 simultaneously with the 2nd inclined plane 50a, thereby form blocked state and releasing state; The filling state of the 2nd Function detection special clip 1 and universal clip 101.
Here, formation described later only is an example, certainly can be corresponding to the geomery appropriate change of clip 1 or 101, also can constitute the discrete mechanism that is used to realize above-mentioned the 1st function and the 2nd function, in the occasion that constitutes the special clip filling mechanism that is used for special clip 1 or universal clip 101, also can be by optics or IC labelling by RF in conjunction with detecting the filling state.
In Figure 16, between the ways that is shown in dotted line 54 and the revoliving arm member 53 of reference Figure 13 A, Figure 13 B explanation, be formed for clip 1 or 101 peristomes that pass in and out.The pedestal 58 that is fixed in the main body 203 of infusion set 200 becomes shape shown from the thick corrosion resistant plate of 1～1.5mm by pressure processing, form the 1st bending section 58a that has transverse projections as shown in the figure like that by pressure processing at this pedestal 58, the 2nd bending section 58c with limiting section, from ways 54 successive the 3rd bending section 58d, the 4th bending section 58k that is used for fixing sensor base plate 68, be used for being fixed to the 58g of installing hole portion of main body, reach the fixedly 58f of hole portion of an end of torsion spring 65 by screw.
Also be pressed into towards vertical direction at this pedestal 58 and be fixed with big column axis body 59 and pillar shape axis body 61, this big column axis body 59 is formed with the slot part that cooperates with back-up ring 62, and this pillar shape axis body 61 is formed with the slot part that cooperates with back-up ring 62.
Compression helical spring 60 enters between the jut 53g of the jut 58a of pedestal 58 and revoliving arm member 53 end 60a, 60b, simultaneously, in order to produce precompressed, slightly is provided with under naturalness with being compressed.As a result, under being contacted with the state of above-mentioned the 2nd bending section 58c, finishes the sliding contact surface 53d of main body 53k.Like this, the compression stress of revoliving arm member 53 resistance compression helical springs 60 is turned round towards counter clockwise direction around axis body 59.
The judgement unit of special clip and universal clip can carry out noncontact and reliable detection by detecting above-mentioned IC labelling.In illustrated occasion, the disk 63 that the axis body 61 around pedestal 58 can be supported freely to rotate is set, the insertion by each clip makes this disk 63 revolutions, detects rotary position optically.Like this, can in limited volume, detect clip.
These disk 63 usefulness prevent that the resin of the black of light transmission from making, form the 63a of through hole portion as the centre of gyration, outer peripheral face notch 63b, recess 63c, and the other end 65c of torsion spring 65 carried out fixed notch 63d.The spiral part undergauge of this disk 63 by torsion spring 65 produces the elastic force ground that will recover end 65b, 65c is set as shown in the figure like that, and axis body 61 backs that are inserted into pedestal 58 can be supported freely to rotate with back-up ring 62 anticreeps.
This notch 63b transmits the turning power of both forward and reverse directions when the 2nd recess 27a of the 1st recess 26a of special clip 1 or universal clip 101 slips into, the power that the inclined-plane of the power that will return of torsion spring 65 and each recess 26a, 27a contacts during simultaneously, by each clip of taking-up is turned round towards primary position.As a result, also can positively turn back to primary position even adhere to the feasible occasion that is difficult to return at medicinal liquid.
In addition, stride across above-mentioned disk 63 ground light-emitting component and photo detector are fixed in sensor base plate 68 along with the revolution of disk 63 detects the 1st pick off 67 of recess 63c and the 2nd pick off 66, sensor base plate 68 is fixed in the bending section 58k of pedestal 58.Except the optical pickocff of such light transmission formula, also can be the pick off of the detection principle of magnetic-type etc.
At Figure 17 A, among Figure 17 B, Figure 17 C, adopt identical symbol for the component parts that has illustrated, omit explanation.Like that, before filling special clip 1 or the universal clip 101, the 1st pick off 67 of the recess 63c of test disks 63 and each optical axis of the 2nd pick off 66 are blocked shown in Figure 17 A.In addition, notch 63b stops in the position of about 15 degree of distance parallel axes.In addition, the sliding contact surface 53d of revoliving arm member 53 applies elastic force by compression helical spring 60 in the position with the parallel axes orthogonal with stopping.
By special clip 1 or universal clip 101 being set to the ways 54 of the peristome that becomes a side who constitutes peristome and becoming between the opposing party's the protuberance 53b of revoliving arm member 53 of peristome towards the direction of arrow, thereby become state shown in state shown in Figure 17 B or Figure 17 C from this state.
Promptly, when special clip 1 fills in the clip filling mechanism, such shown in Figure 17 B, the front end of the insertion guide part 26 of special clip 1 is met the contact surface 63b-1 with the notch 63b of disk 63, and the protuberance 63b-2 of notch 63b enters the 1st recess 26a in succession, around axis body 61 revolution predetermined angulars, disk 63 stops, the optical axis of the 1st pick off 67 is not blocked, so, detect recess 63c.At this moment, protuberance 53b crosses the outer peripheral face of the 2nd elastic supporting part 40, produces the sense of joint degree, and simultaneously, the 33a of restriction portion is contacted with spacing member 58c, prevents further insertion.
On the other hand, in the ground plan of the state after schematically illustrating of Figure 17 C fills in the clip filling mechanism with universal clip 101, when universal clip 101 is loaded into the clip filling mechanism, such as shown in the figure, the front end of the insertion guide part 27 of special clip 1 is met the contact surface 63b-1 of the notch 63b of disk 63, and the protuberance 63b-2 of notch 63b enters into the darker position of the 2nd recess 27a in succession.
As described above, because it is longer than the occasion of special clip to insert guide part 27, so disk 63 stops in the position of 15 degree that further turned round predetermined angular, the optical axis of the 2nd pick off 66 is not blocked, so, detect recess 63c.At this moment, protuberance 53b similarly crosses the outer peripheral face of the 2nd elastic supporting part 40, produces the sense of joint degree, and like this, restriction portion 25 is contacted with ways 54, prevents further insertion.
When above filling, revoliving arm member 53 is loaded and extracts in sliding contact surface 53d ground by reinforcement guide part 30 sliding-contacts of clip.As a result, the compression stress of revoliving arm member 53 resistance compression helical springs 60 obtains to keep sense towards counterclockwise turning round slightly.
About the clip filling mechanism that constitutes as described above, describe according to Figure 18 A and Figure 18 B, Figure 18 A opens door 204 for watching from the below, special clip 1 is filled in the state before the clip filling mechanism and with cross hatch the sectional view of revoliving arm member 53 is shown, and Figure 18 B is the sectional view that the state behind the clip filling mechanism that special clip 1 is loaded into is shown.
In this figure, adopt identical symbol for the component parts that has illustrated, omit explanation.When door 204 is opened, the 1st inclined plane 50c of dip member 50, the 2nd inclined plane 50a, and the 3rd inclined plane 50d carry out keeping out of the way of big distance as shown in the figure like that.In addition, the sliding contact surface 53f of the main body 53 of revoliving arm member 53 is positioned at the position relative with ways 54, and the special clip 1 that makes tube for transfusion 2 become blocked state is inserted into the peristome that is formed at therebetween along the direction of arrow.At this moment, the sliding contact surface 53d of revoliving arm member 53 is contacted with the ribs 37 of clip 1, so, can obtain appropriate resistance.In addition, strengthen guide part 30 and be set to the guiding groove section of ways 54, thus prevent under the state of table back side counter-rotating misplug into.In addition, this moment, disk 63 stopped at and identical position, position shown in Figure 17 A.
Then, in Figure 18 B, obtain joint degree sense ground and as described above special clip 1 is loaded into the clip filling mechanism, thereby become and the identical state of state shown in Figure 17 B.As a result, the signal of telecommunication of origin autobiography sensor 67 has loaded this state notifying infusion set 200 with special clip 1.Then, door 204 is closed towards the direction of arrow.
The door 204 of Figure 19 A is closed, and becomes special clip 1 and revoliving arm member 53 state by dip member 50 pushings.That is, the pushing face 41a of special clip 1 removes the direction pushing by the 2nd inclined plane 50a joint inwards of dip member 50, begins like that to remove shown in Fig. 2 B.Meanwhile, the sliding contact surface 53f of revoliving arm member 53 is by the 1st inclined plane 50c pushing of dip member 50, thereby the compression stress of resistance compression helical spring is as shown in the figure like that towards revolution counterclockwise.
Then, in Figure 19 B, door 204 is further closed, and infusion set between the angle that constitutes when becoming the 1 degree left and right sides, the pushing face 41a by the 2nd inclined plane 50a further pushes special clip 1 becomes the state that will remove joint.
Then, like that, door 204 is closed at last and when locking, special clip 1 is disengaged shown in Figure 20 A, and the obturation of tube for transfusion is disengaged.At this moment, the 2nd pushing face 41a that extends portion 41 drops into the paddy portion of dip member 50 by elastic force, becomes original naturalness in moment, like this, permanent deformation can not take place.In addition, revoliving arm member 53 moves to position of readiness as described above, so the secondary base portion of the formation ribs 37 of special clip 1 is towards revoliving arm member 53 side shiftings.Like this, become the state that transfusion can be carried out.
Because changed the application point that produces the needed load of joint of removing clip as described above, so, can close door 204 by lighter power.
Under this state, infuse by vermicular movement as described above.
After this transfusion finished, when the locking of removing door 204 shown in Figure 20 B like that began to open, the 1st inclined plane 50 of dip member 50 began to leave from sliding contact surface 53f, thereby made 53 beginnings of revoliving arm member towards right pushing special clip 1.In addition, the 2nd inclined plane 50a of dip member 50 begins to leave from the 2nd pushing face 41a that extends portion 41 at this moment.
Then, like that, when the angle 8 degree left and right sides are further opened, become to door 204, revoliving arm member 53 moved to the pushing position shown in Figure 21 A, and special clip 1 turns back to the blocked state of engagement state and tube for transfusion.Then, like that, door 204 is opened, and becomes the state that can take out shown in Figure 21 B.
At last, take out in the sectional view of state of special clip illustrating of Figure 22 A, the nurse from the handle part of catching special clip 1 up and down forward layback go out, can obtain maintenance sense as described above this moment.In addition, when pulling out, shown in Figure 22 B, like that, make disk 63 revolutions forcibly, thereby turn back to original primary position.
Like this, notch is set, this notch can detect the clip of special-purpose infusion set and the clip of general infusion set automatically, and, become the non-test section that parallel motion conversion when clip loaded is transformed into gyration, in addition, be arranged side by side 2 light transmission formula pick offs, and, by torsion spring disk is set to position of readiness, thereby can be set to limited space.In addition, when pulling out clip as described above, because disk turns back to original position by notch, so, make and to become the state that can not return by torsion spring even medicinal liquid adheres to (after drying), also can turn back to original position forcibly, when using next time, can use no problemly.
Figure 23 is the action specification flow chart that is used for the automatic detection of special clip 1 or universal clip 101.In the figure, at step S1, as reference Figure 15 explanation, clip and tube for transfusion etc. are set.The occasion of general infusion set is being set, the drop tube is being set to the some drip apparatus with drop inspection probe, necessarily will put drip apparatus and be connected with infusion set.
Then, in step S2, by making on and off switch 15 connect for 1 second under door 204 the state opening, thereby make the initialize routine start, carry out each unitary initialization and self check,, alarm takes place, forbid action after this when certain taking place when unusual.
