Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression hemostasis belt used to stop a catheter insertion wound after performing an arterial catheter examination or the like.

[0002]

2. Description of the Related Art Arterial catheter examinations have recently been performed for contrast diagnosis of hearts, cerebral blood vessels, and the like.
Cardiac catheterization may be performed by an incision method as a small number of cases, but most of it is performed by a so-called catheter puncture method (Seldinger method) in which a catheter is advanced from the femoral arteries and veins of the groin to the heart. There is. 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 compress the wound for a considerably long time. As such a method for compressing and bleeding a wound, a bandage hemostasis method or an expansion / contraction tourniquet method (see JP-A-60-92746 and JP-A-60-198139) has been proposed.
The former applies gauze to the wound and puts a cloth bandage on it.
It is a method in which 4 to 4 pieces are adhered and the wound is pressed from above the gauze, 500 to 1000 g of sandbag is further placed on the adhesive plaster, and this is fixed with the adhesive plaster and maintained for 12 to 24 hours. However, this method has a problem in that hemostasis at the wound is incomplete because the compressed area is likely to be displaced due to the displacement of the sandbag. Also, because I use a bandage,
There is a problem that the patient feels tightness, pain, or pruritus, and that dermatitis and blisters are likely to occur. 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.

In view of these problems, the present applicant has proposed a pressure hemostatic belt as shown in FIG. 5 in Japanese Patent Application No. 4-20793 as a wound hemostatic means.

As shown in FIG. 5, the compression / hemostatic belt has a pocket (2) formed at a predetermined position of a band (1) made of non-stretchable or low-stretchable fiber or film. A hard case (3) and a balloon (4) are housed inside (2). The hard case (3) is made of a hard material such as synthetic resin in a bowl shape, and the balloon (4) is made of rubber or the like, and the pocket (1) of the band (1) ( The fluid supply pipe (6) having the check valve (5) in 2) is housed in the hard case (3) in a state of protruding to the outside. For example, a manually operated pump (7) and a pressure gauge (8) are connected to the fluid supply pipe (6) of the balloon (4) as required. By operating the pump (7) while observing, the fluid is filled into the balloon (4) through the fluid supply pipe (6) and the balloon (4) is inflated.

The usage of the above-described compression / hemostatic belt will be described below.

As shown in FIG. 6, a gauze (B) is applied to a wound (A) for inserting a catheter, and a pocket (2) accommodating a hard case (3) and a balloon (4) is placed on the gauze (B). After placing the hard case (3) with the opening side facing the gauze (B) side, as shown in FIG.
The band (1) is wrapped around the body of the patient. That is, the band (1) is wound around the foot in an X shape, the remaining part is wound around the waist once or more, and the end is locked with a bandage or the like. Then, a manually operated pump (7) and a pressure gauge (8) are connected to the fluid supply pipe (6) of the balloon (4).
By connecting the pump and operating the pump (7) while observing the pressure gauge (8) to fill the fluid in the balloon (4).
As shown by the chain double-dashed line in FIG. 6, the balloon (4) is expanded by the hard case (3) to the opposite side of the wound (A) to the wound (A) side, and the gauze (B) is then expanded. While pressing the wound (A) through the, the band (1) is firmly fixed to the patient.

As described above, the compression / hemostatic belt compresses the wound (A) by utilizing the expansion of the balloon (4), so that only the wound (A) can be compressed and the other parts are not compressed. The feeling of oppression hardly propagates. Also, pressure gauge (8)
By operating the pump (7) while looking at, the magnitude of the compression force applied to the wound (A) can be freely selected, and the compression force selected by the check valve (5) can be maintained for a long time. It is also possible to maintain. Furthermore, since the non-stretchable or low-stretchable fiber cloth is used for the band (1), the occurrence of tension, pain, or itching is avoided, and dermatitis and blisters are also prevented. ,
It is provided with various features such that it can be provided at a low price, it can be disposable only once, and that remarkable effects can be exerted also for improvement of hygiene management and promotion of labor saving.

[0008]

By the way, when the conventional compression and hemostatic belt is wound around the foot in an X shape, the end of the band (1) is locked to the middle portion of the compression and hemostatic belt with a bandage or the like. However, it was troublesome to prepare a bandage each time.

It is an object of the present invention to provide a compression / hemostatic belt in which locking of the end portion of the band is simple.

[0010]

In order to achieve the above-mentioned object, the present invention is expandable by filling a fluid inside a band made of non-stretchable or low-stretchable fiber, nonwoven fabric or film. In a compression hemostatic belt having a balloon, a buckle having slit holes at both ends through which both ends of the band are inserted is attached to the above band. Both ends of the strip after passing through the slit holes can be fixed, for example, at the slit holes, or can be folded back on the opposite side to be attached / detached to / on the side surface of the strip with a locking means with one touch.

In addition, the core material can be embedded in the portions corresponding to the foot portion and the waist portion of the band member when wrapped around the body.

Further, of the above band, the portions corresponding to the legs and the waist when wrapped around the body can be formed by the reinforcing member.

Further, a hard case is interposed between the band and the balloon, the hard case and the buckle are rotatably coupled by the center pin, and the balloon is provided along the axis of the center pin. Through holes are formed from the upper surface to the buckle surface.

[0015]

Since the both ends of the strip are inserted into the slit holes of the buckle and folded back, and the folded ends can be fastened to the side surface of the strip with one touch, the so-called X-shaped looping of the strip can be performed quickly and reliably. .

In addition, by burying a core material in a portion corresponding to the foot portion and the waist portion of the band when it is wrapped around the body or forming the portion by a reinforcing member, wrinkles and wrinkles in the foot portion and the waist portion can be obtained. It has become possible to prevent twisting.

Further, by rotatably attaching the buckle to the band, it is possible to arbitrarily set the crossing angle of the X-shaped wrapping and enhance the fit of the band to the body. The ideal wrapping angle of the body has made it possible to reliably prevent wrinkles from occurring due to unreasonable angling of the band.

Further, by attaching the buckle to the belt through the center pin having the through hole in the hard case for accommodating the balloon, the inflation state of the balloon can be easily confirmed from the outside of the buckle through the through hole. Became.

[0019]
