DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a hemostatic member and a hemostatic device used in medical treatment.

[0002]

2. Description of the Related Art Blood collection, transfusion, infusion,
When performing artificial dialysis, arteriovenous contrast, arteriovenous embolization, catheter-like angioplasty, and the like, it is often performed to puncture a blood vessel with a catheter, a syringe needle, or the like. After removing the catheter, the injection needle, and the like from the blood vessel, it is necessary to stop the puncture at the punctured part. This hemostatic work was usually performed by doctors or nurses, but the time that can be spent on the hemostatic work during busy work is limited, and the development of effective hemostatic tools that can easily and reliably stop the hemostasis has been developed. Is desired.

As a conventional hemostatic device, there is known a hemostatic adhesive material in which a pressing plate is attached to the center of an adhesive tape and a pad is fixed on the pressing plate (Japanese Patent Laid-Open No. 7-241).
313 publication). Such an adhesive material for hemostasis is used by applying an adhesive tape to a portion to be attached such as an arm while applying the pad to a puncture portion. However, it is difficult to obtain a pressing force necessary for hemostasis only by sticking with an adhesive tape, and a sufficient hemostasis effect may not be obtained. In addition, if the adhesive tape is peeled off after the adhesive tape is once adhered to adjust the tension, the adhesive force at the time of re-adhesion is extremely reduced, so that it is difficult to adjust the tension and hence the pressing force.

[0004] In view of the above, for example, a binding belt that can be wound around a portion to be attached, such as an arm or a foot, and that can be adjusted in length, and a pressing plate adhered to a substantially central portion of one surface of the binding belt. A hemostatic device has been proposed which comprises an elastic pad provided on a non-adhesive surface of the pressing plate (Japanese Patent Laid-Open No. 8-140990). Since such a hemostatic device is attached to a portion to be attached such as an arm by a belt whose length can be adjusted, the pressing force of the pad against the puncture portion can be adjusted by appropriately adjusting the length of the belt, and readjustment can be performed. This has the advantage that it can also be performed.

[0005]

However, both the hemostatic patch using the adhesive tape and the hemostatic device using the belt have a single-layer structure in which the pad is made of a plastic foam, or a plastic foam and a compressed cotton. Due to the multi-layer structure of the above, there is a problem that the elasticity is reduced in a short time (in this specification, it may be referred to as a "set phenomenon"). When such a settling phenomenon of the pad occurs, the pressing force adjusting action of the pad, which appropriately buffers the pressing force applied to the absorbent cotton or the like applied to the puncturing portion, is reduced, so that the puncturing portion can be effectively pressed. The hemostatic effect is lost. In consideration of this point, it is conceivable to increase the thickness of the pad in order to maintain the elasticity of the pad, but this is not only an essential solution to the sagging phenomenon, but also makes the pad more likely to shatter or fall down and stop bleeding. A new problem arises in that the reliability of work is reduced.

[0006] Furthermore, since the pad once used for hemostatic work absorbs blood, it must be disposed of due to sanitary problems.
It is not preferable in terms of an environment that causes an increase in medical expenses and an increase in difficult-to-treat medical waste.

[0007] Therefore, an object of the present invention is to provide a hemostatic member and a hemostatic device capable of appropriately and continuously pressing a puncture portion and being used repeatedly.

[0008]

According to the present invention, there is provided a hemostatic member which is attached by a fixing tool 6 to stop a puncture portion 7 such as an arm, and has elasticity.

Since the hemostatic member 2 according to the present invention has elasticity, the pressing force applied by the fixing device 6 such as a fixing band can be moderately reduced, so that the pressing force suitable for hemostasis is applied to the puncture portion 7. be able to. In addition, since the pressing force is concentrated on the protruding end outer surface 14 of the protrusion 3, even when the fixing tool 6 is wound with relatively weak tension, it is necessary to apply a sufficient pressing force to the puncture portion 7 to exert a hemostatic effect. it can. Therefore,
The tension around which the fixture 6 is wound can be reduced, and congestion or the like of the attached portion 16 such as an arm can be prevented. Further, since the hemostatic member 2 according to the present invention is composed of the plate-like body 4, the elasticity is not easily reduced even when a force is applied for a long time,
The puncture unit 7 can be continuously and appropriately pressed.

Further, if the elastic plate-like member 4 is formed of a metal or synthetic resin molded product,
Since it can be sterilized and disinfected by a usual method such as heat treatment or alcohol treatment, it can be used repeatedly, and becomes a sanitary and economical hemostatic device. Further, since the projection 3 is provided at substantially the center of the plate-like body 4, when the projection 3 is applied to the puncture portion 7 and a pressing force is applied by the fixing tool 6 to attach the hemostatic member, the hemostasis is stopped. Member 2 is less likely to be inadvertently tilted.

Further, as in claim 3, the protrusion 3
Is formed flat, the hemostatic member 2 is less likely to fall down when the hemostatic member 2 is brought into contact with the puncture portion 7, and the grounding surface with the puncture portion 7 Because it is hard to slide widely, it can be easily attached using the fixing tool 6, and after the attachment, the tightening force of the belt is uniformly applied to both ends of the hemostatic member 2, so that the hemostatic member 2 is hardly displaced. . Further, when the plate-like body 4 is formed of a transparent or translucent member as in claim 4, the state of an absorbent such as gauze, the state of bleeding, and the like are seen through the hemostatic member 2. Can be confirmed. Therefore,
Adjustment of the pressing force by retightening the fixture 6 and replacement of the absorber 8 can be performed appropriately in accordance with the hemostatic condition, so that the reliability and safety of the hemostatic work can be improved.

As another means, there is provided a hemostatic device used for hemostasis of a puncture portion 7 such as an arm, wherein the elastic member has a protruding portion 3 provided on one surface 4a of a plate-like plate 4. 2 and the protrusion 3 of the hemostatic member 2
A belt 6 for fixing the belt 6
Provides a self-adhesive hemostatic device. If such a hemostatic device 1 is used, the belt 6 for attaching the hemostatic member 2 to the puncture portion 7 such as an arm has self-adhesiveness.
By winding the belt 6 around an arm or the like and overlapping each other, the belts adhere to each other and can be easily attached. Therefore, it becomes easy to adjust the length of the belt,
Adjustment of the pressing force applied to the hemostatic member is also facilitated, so that a more preferable hemostatic device is obtained.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a hemostatic device 1 is fixed to a hemostatic member 2 of a plate-like body 4 having elasticity. Tool 6.

As shown in FIGS. 3 to 5, the hemostatic member 2 has an elastic plate-shaped member 4 made of a metal or synthetic resin molded product having a predetermined size, and is provided at substantially the center of one surface 4a. And has a length slightly shorter than the width of the plate-like body 4 and has a shape in which the elongated protrusion 3 is integrally formed by being formed into a convex shape so as to have a smooth periphery of the tip end outer surface 14. The protruding end outer surface 14 of the projection 3 is formed so as to be a plane parallel to the other surface 4b of the plate-like body 4 (a rectangular shape whose four corners in bottom view are arc-shaped). The protruding end outer surface 14 of the protruding portion 3 is formed with an appropriate area such that the pressing force generated by the elasticity effectively presses the puncture portion 7, and the entire corner portion of the protruding end outer surface 14 is chamfered. It is formed in a curved shape (like drawing a smooth curve). Further, insertion holes 5 for mounting fixtures are provided on both sides in the longitudinal direction of the plate-like body 4 around the protrusion 3, and the plate-like body 4 is provided at a substantially central portion thereof in the direction of the protrusion 3. A notch 9 is provided facing the same. The hemostatic member 2 is appropriately bent when a load is applied to the left and right side ends of the plate-like body 4 in the direction of the protrusions 3 with the protruding end outer surface 14 as a fulcrum, while the original shape is obtained when the load is removed. It is molded with elasticity to restore it to Such a hemostatic member 2 has, for example, a thickness of about 0.5 to 3 mm and a length A of about 50 to 10 mm.
A protruding portion 3 having a height C of approximately 10 to 30 mm is formed integrally with a substantially central portion of one surface 4a of a metal (eg, aluminum) plate 4 having a thickness of approximately 0 mm and a width B of approximately 20 to 50 mm. Can be obtained.

Next, as the fixing tool 6, a belt having a length that can be wound around a portion to be mounted such as an arm, and a self-adhesive belt or the like is used.
Such a self-adhesive belt is, for example, a belt made of a synthetic resin band having a thickness of several mm to which a weak adhesive is applied, or a surface treatment in which the wettability of the surface of the synthetic resin band is enhanced. And the like, specifically, vinyl chloride resin and the like.

If necessary, a connecting portion 11 provided with an opening 15 through which the other side of the fixing tool 6 can be inserted may be provided at one longitudinal end of the fixing tool 6.

One end of the fixing device 6 is connected to one insertion opening 5 of the hemostatic member 2 by a surface provided with the projection 3.
The hemostatic device 1 is configured by being inserted from the a) side and being inserted into the other insertion opening 5 through the surface of the member 2 for hemostasis opposite to the projection 3.

Next, a method of using the hemostatic device 1 and its effects will be described with reference to FIGS. First, the protruding end outer surface 14 of the projection 3 of the hemostatic device 1 is brought into contact with an absorbent body 8 such as absorbent cotton temporarily placed on the puncture portion 7 of the blood vessel 12, and then the belt 6 is attached to the arm or the like. It winds around the to-be-attached part 16. When tension is applied to the belt 6 while checking the pressing state of the puncture portion 7 by the protrusion 3 via the absorber 8,
By gradually increasing the pressing force and overlapping the belts 6 at appropriate places, the belts 6 adhere to each other due to their adhesiveness, and the hemostatic device 1 can be attached to the attachment portion 16 such as an arm. Since the hemostatic member 2 has elasticity, it is curved with the protrusion 3 as a fulcrum by the tightening force of the belt 6, and the puncture portion 7 is pressed via the absorber 8 by the restoring force. . At this time, since the notch 9 is provided at the center of the hemostatic member 2, the hemostatic member 2 can be appropriately and smoothly curved. In addition, since the force applied to the hemostatic member 2 from the belt 6 is concentrated on the protruding end outer surface 14 of the protrusion 3,
Even when the belt 6 is wound with a relatively weak tension, a sufficient pressing force that exerts a hemostatic effect can be applied to the puncture portion 7. Therefore, the tension around which the belt 6 is wound can be reduced, and congestion or the like of the attached portion 16 such as an arm can be prevented.

Further, since the protruding end outer surface 14 of the projection 3 is flat, a reliable hemostatic effect can be obtained. That is, the tension of the belt 6 is likely to be non-uniform at both ends of the hemostatic member 2, and the hemostatic member 2 may be inclined with the protruding portion 13 as a fulcrum. If the shape of 14 is flat, it is possible to prevent the hemostatic member 2 from inadvertently tilting when the belt 6 is tightened, and it is possible to improve the reliability of the hemostatic work. Also,
Since the protruding portion 3 is provided substantially at the center of the plate-like body 4, the tension of the belt 6 can be balanced, and the inadvertent tilting of the hemostatic member 2 when the belt 6 is fastened can be prevented. In addition, since the protruding end outer surface 14 of the protruding portion 3 is formed into a smooth curved shape that is chamfered, it is possible to stop bleeding without causing pain to the skin surface around the pressed puncture portion.

Further, since the belt 6 has a self-adhesive property, it can be adhered only by folding back through the opening of the connecting member 11 and overlapping the surfaces of the belt 6 with each other. Further, even after attaching the hemostatic member 2 by the belt 6, by peeling off the overlapped portion of the belt 6,
Since the fastening of the belt 6 can be easily released, readjustment of the length and the tension after the attachment can be easily performed.

In the above embodiment, the hemostatic member 2 is used.
Has a configuration in which the substantially central portion of the one surface 4a of the plate-shaped body 4 is protruded and the projection 3 is integrally formed. However, the hemostatic device 2 is not necessarily limited to being integrally formed. ,
A configuration in which the protrusion 3 is separately fixed to one surface 4a of the plate-like body 4 having elasticity may be employed. Further, in the above embodiment, since the protruding portion 3 is formed in a long shape along the direction of the blood vessel 12, it can press the linear blood vessel over a wide range when it comes into contact with the puncture portion 7. For this reason, there is an advantage that hemostasis can be performed effectively, but the projection 3 is not necessarily limited to a protruding projection. Further, in the above-described embodiment, the protruding portion 3 is formed to have a length slightly shorter than the width of the plate-shaped body 4, but as shown in FIG. It may be formed by bending.

Further, in the above embodiment, since the hemostatic member 2 is formed of a metal or synthetic resin molded article, there is an advantage that sterilization and disinfection by heat treatment or alcohol treatment can be repeatedly performed. However, the hemostatic member is not necessarily limited to a member formed of a metal or synthetic resin molded product, and is not particularly limited as long as it has a predetermined elasticity and is a plate made of a natural material such as wood or bamboo. It may be composed of a shape.

Further, if the hemostatic member 2 is formed of a transparent or translucent material, the state of blood absorption of the absorber 8 can be seen through, and the hemostatic operation is performed again according to the hemostatic state. It is preferable because it can be used.

In the above embodiment, the protruding end outer surface 14 of the projection 3 of the hemostatic member 2 is formed as a plane, but is not necessarily limited to the plane.
The protruding end outer surface 14 of the protrusion 3 may be formed into a shape formed into a corrugated plate, a shape formed into a curved surface having a large radius of curvature, or the like.

Further, in the above embodiment, the fixture 6
Is a belt, but is not limited to a belt as long as it can be wrapped around an attached portion 16 such as an arm or a foot to fix the member 2 for hemostasis. You may use the belt-shaped body made from a product. Moreover, in the said embodiment, although the fixture 6 has self-adhesiveness and the structure attached to each other by self-adhesion is illustrated, it is not necessarily limited to the structure attached to each other by self-adhesiveness, for example, A hook-and-loop fastener (a hook surface and a loop surface are engaged) or a fixing bracket (for example,
Buckle).

It should be noted that, in the above-mentioned usage form, the hemostatic member 2
The absorbent body 8 to be interposed between the puncture part 7 and the puncture part 7 may be made of commonly used absorbent cotton or gauze, but does not prevent the use of a pad used in a conventional hemostatic device. .

[0026]

As described above, if the hemostatic member and the hemostatic device according to the present invention are used, the puncture portion when the catheter, the injection needle or the like is removed is pressed by the intended pressing force to surely stop the hemostasis. be able to. In addition, since the pressing force is concentrated on the outer surface of the protruding end of the protrusion, even when the fixing tool is wound with relatively weak tension, a sufficient pressing force that exerts a hemostatic effect can be applied to the puncture portion. Therefore, the tension for winding the fixing device can be reduced, and congestion or the like of the attached portion such as the arm can be prevented. Furthermore, since the pressing force utilizes the elasticity of the hemostatic member, which is a plate-like body, it is unlikely that a change over time such as settling occurs, and a constant pressing force is applied for an extremely long time. Can be. Therefore, the puncture part can be pressed moderately and continuously, and the puncture part can be reliably stopped. In addition, since the hemostatic member can be subjected to heat treatment and alcohol treatment for the purpose of disinfection and sterilization, it can be used repeatedly, and is economical with less generation of medical waste.

If the outer surface of the protruding end of the projection of the hemostatic member is formed in a flat shape, the hemostatic member is unlikely to tilt and the grounding surface with the puncture portion is unlikely to slide, so that it is difficult to mount the hemostatic member. Work can be performed easily. In addition, there is an advantage that the hemostatic member is less likely to be displaced after mounting.

Further, when the hemostatic member is transparent or translucent, it is easy to grasp the condition of the absorber on the puncture part and the skin around the puncture part, and it is necessary to take measures such as readjustment of the hemostatic device. Easy to do.
