Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression / hemostatic belt used for stopping bleeding at a catheter-inserted wound after performing arterial catheter inspection or the like.

[0002]

2. Description of the Related Art Arterial catheter examinations have recently been performed for diagnostic imaging of the heart and cerebral blood vessels.
Cardiac catheterization may be performed by an incision method as a small number of cases, but most of the time, the so-called catheter puncture method (Selzinger method) in which a catheter is advanced from the femoral arteriovenous (or brachial artery) of the groin to the heart ). In this test method, contrast media and various drugs are injected through a catheter punctured in the femoral artery and vein, and emporization and various pre- and post-operative tests are performed. In order to prevent bleeding from a catheter-inserted wound due to removal of the catheter from the arteriovenous vein, it is necessary to press the wound for a considerable period of time to stop bleeding. As such a method for compressing and bleeding a wound, a bandage hemostatic method or a stretchable tourniquet method (see JP-A-60-92746 and JP-A-60-198139) has been proposed. The former applies gauze to the wound, adheres 3 to 4 cloth adhesive plasters on it, presses the wound from above the gauze, and further 500 to 10 on the adhesive plaster.
This is a method of placing 00 g of sandbag, fixing it with a plaster and maintaining it for 12 to 24 hours. However, this method has a problem in that hemostasis at the wound is incomplete because the compressed region is likely to be displaced due to the displacement of the sandbag. Further, since the adhesive bandage is used, there is a problem that the patient feels tightness, pain, or pruritus and easily causes an adhesive bandage rash. On the other hand, the latter is a method of using an elastic tourniquet instead of the bandage, but has a problem that the winding method is complicated and the compression load state is unstable. In addition, since the elastic tourniquet is used, the cost is high, and it is difficult to dispose of it only once even though there is a sanitary problem that blood infection occurs. For this reason, when it is reused, it must be sterilized to prevent blood-borne infections, and there are significant practical restrictions not only from a hygienic point of view, but also in promoting labor saving in nursing work. There is a problem that is.

Therefore, in order to solve the above-mentioned problems, the applicant of the present invention, in Japanese Patent Application No. 4-20793, fills a predetermined position of a strip made of non-stretchable or low stretchable fiber or film with a fluid. A hemostatic belt has been proposed which attaches an inflatable balloon by any attachment means and uses the inflation of the balloon to press the wound. According to this compression hemostatic belt, since the wound is compressed by utilizing the inflation of the balloon, only the wound can be compressed, and the compression force can be adjusted, and the compression force can be maintained for a long time. It is also possible to maintain it throughout. In addition, since non-stretchable or low-stretchable fibers or films are used for the band, it is possible to avoid the occurrence of tension, pain, or itching, prevent bandage rash, and provide at low cost. It can be used once and can be used only once and is excellent in hygiene.

Further, the applicant of the present invention discloses in Japanese Patent Application No. 4-325049 the above-mentioned band for the purpose of improving the fit to the body, simplifying the winding of the band and the locking of the end of the band. When wound around the body, the part corresponding to the foot is formed into a curved shape,
Also, a compression / hemostatic belt is proposed, in which a buckle having slit holes at both ends is rotatably attached to the band member, and locking means that is detachable with one touch is provided at both end parts of the band member. .

[0005]

However, in each of the above-described compression / hemostatic belts, a locking means such as a double-sided tape or a velcro tape is used to lock the end of the band, and such a double-sided tape or velcro is used. If the locking means such as tape is repeatedly locked, the adhesive force will decrease, so the band may be detached or loosened during mounting, and the mounting position of the locking means depends on the body type of the patient. Since it is different, it was necessary to prepare several types of lengths (sizes) of the band depending on the body type of the patient.

The present invention has been made in view of the above problems, and it is easy to wind and lock the band, and there is no detachment or looseness of the band after winding, and the length of the band is long. It is also an object of the present invention to provide a compression hemostatic belt that can handle only one type.

[0007]

In order to achieve the above object, the present invention can be expanded by filling a predetermined position of a band made of non-stretchable or low-stretchable fiber, nonwoven fabric or film with a fluid. A compression hemostatic belt in which a balloon is attached by an arbitrary attachment means, and a rotatable buckle having slit holes at both ends is integrally attached together with a band to a hard case that covers the balloon and has an opening on the lower side. A band holding jig capable of fixing the band is provided at both ends of the.

Further, the band pressing jig is composed of a fixed portion integrally extended from both ends of the buckle and a movable portion rotatably supported by the fixed portion. The gap with the fixing part becomes wide when passing the band and disappears when fixing the band.
The cross-sectional shape is asymmetric with respect to the center of rotation.

Further, the cross-sectional shape of the movable portion of the band pressing jig is formed into a substantially semicircle.

Further, a plurality of non-slip streaks are provided on the surfaces of the fixed part and the movable part of the band pressing jig.

Further, the slits provided at both ends of the buckle are provided with a backflow preventing projection for locking the movable part of the band pressing jig when fixing it to the band.

[0012]

[Function] By providing the band holding jig capable of fixing the band at both ends of the buckle, it becomes possible to fix the band at any position with the band holding jig. No need for locking means such as double-sided tape or velcro tape on the part, and by cutting the extra part of the unwound band with scissors, a little longer type of band can be used for most patients. I was able to respond.

Further, by rotating the movable part of the band pressing jig, the gap between the movable part and the fixed part is widened when the band is passed through, and is eliminated when the band is fixed so that the gap between the fixed part and the fixed part is eliminated with respect to the rotation center. By forming the asymmetric cross-sectional shape, it became easier to pass the strip.

Also, in the slit holes at both ends of the buckle,
By providing the reversion prevention projection that locks the movable part of the band holding jig when fixing the band, it is possible to securely fix the band without the loosening of the band due to the reverse return.

It is inflated to the side to compress the catheter insertion wound and at the same time, the band (1) is firmly fixed to the body.

According to the compression hemostatic belt of the present invention, after the band (1) is wound, any part of the band (1) can be fixed by the band pressing jig (8), and , The movable portion (10) of the band pressing jig (8) is provided with a reversion preventing projection (9) formed in the slit hole (6a) of the buckle (6).
Since it is locked to b), the band (1) does not loosen due to the reverse movement, and it is possible to securely fix it. Therefore, the strip (1) may come off when wrapped,
There is no risk of loosening and effective pressure bleeding can be achieved, and the conventional locking means (double-sided tape, velcro tape, etc.) that can be attached and removed at both ends of the band (1) is not required. Therefore, the manufacturing cost can be reduced. Also, if the excess portion of the unwound strip (1) is cut with scissors, one type of strip (1) slightly longer
Can handle most patients, and it is no longer necessary to prepare many kinds of strips (1) having different lengths (sizes) as in the conventional case. Furthermore, the movable part (10) of the holding jig (8)
Is formed in an asymmetrical cross-sectional shape with respect to the center of rotation of the rotation shafts (10a) (10a), the gap between the fixed part (9) and the movable part (10) is small when the band (1) is passed through. It becomes wider and the band (1) can be easily inserted. For this reason, the winding and fixing of the band (1) around the body have become extremely easy.

In the above embodiment, a part of the strip (1) is formed in a curved shape in order to be wound easily and with a good fitting property. It goes without saying that it is possible to wrap it around the body without forming a part of it into a curved shape. Further, a core material made of a material such as PET or cardboard may be internally provided in the band (1) so that wrinkles and kinks do not occur. At this time, the core material provided in the portion around which the foot is wrapped has a recess so that the crotch portion does not slip. Further, in the embodiment, the hard case (2) is integrally attached to the band (1) through the center pin (7) together with the buckle (6), but a pocket is formed in the band (1).

[0025]

As described above, according to the present invention,
Since any part of the band can be fixed to the buckle with a holding jig, and the movable part of the holding jig that fixes the band can be locked, the band may loosen due to backward movement. It is possible to achieve reliable pressure fixing, and there is no risk that the band will come off or loosen when wrapped, and effective pressure hemostasis can be achieved, as well as attaching and detaching to both ends of the band with one touch as in the past. Since the possible locking means (double-sided tape, velcro tape, etc.) is not required, the manufacturing cost can be reduced. Further, by cutting the extra portion of the unwound strip with scissors or the like, one kind of strip having a slightly longer length can handle most patients. Furthermore, when the movable part of the band pressing jig is rotated to fix the band, the direction of rotation of the movable part is a direction in which the band is tightened more strongly, so that hemostasis can be made more reliable.
