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.
In some cases, cardiac catheterization is performed by an incision method, but most are performed by the so-called catheter puncture method (Seldinger method) in which the catheter is advanced from the inguinal femoral artery to the aorta. I have. In this test method, a contrast medium and various drugs are injected through a catheter punctured into the femoral artery and vein, and various tests are performed after emporization and preoperative surgery. In order to prevent bleeding from the catheter insertion wound due to removal of the catheter from the vein, it is necessary to compress the catheter insertion wound for a considerably long time. As a method for stopping the hemorrhage of such a catheter insertion wound, conventionally, after a hand or a doctor or a nurse presses the catheter insertion wound for about 15 minutes, a gauze is applied to the catheter insertion wound, and a length of 70 cm is placed on the gauze. Adhere 3 to 4 pieces of cloth bandage about 5 cm in width, press the catheter insertion wound from above the gauze, and place a sandbag adjusted to about 500 to 1000 g on the cloth bandage,
The sandbag was fixed with a cloth bandage so as not to move, and the fixed state was maintained for 12 to 24 hours.

However, in the above-mentioned conventional method, since the gauze applied to the wound for inserting the catheter after the removal of the catheter and the bandage is used as a means for fixing the sandbag placed on the gauze, a feeling of tension, pain, or pruritus is felt. It is not uncommon for dermatitis and blisters to occur as well as for the occurrence of blemishes. In addition, the compression part is likely to be displaced, and even if the patient is lying on his back, the sandbag is easily dislodged by tilting the body a little, so that the hemostasis of the wound becomes incomplete and inconvenience such as subcutaneous hematoma is also induced.

[0004] On the other hand, in order to solve the above-mentioned problem, as a means for compressing and stopping a catheter insertion wound in place of a bandage and a sandbag, for example, JP-A-60-92746 or JP-A-60-92746
Japanese Patent Application Publication No. 198139 discloses a compression hemostatic belt made of an elastic fiber cloth. However, with these compression hemostatic belts, the winding method is complicated, and it is not possible to visually confirm the level of the compression force acting on the catheter insertion wound, and when adjusting the compression force, the compression hemostasis belt is used. Has to be rewound, and the load state of the pressure becomes unstable. Further, since expensive stretchable fiber cloth is used, the production cost of the compression hemostasis belt increases, and it is difficult to dispose of the belt in spite of the hygienic problem of the occurrence of infection due to blood adhesion. Therefore, in order to prevent blood infectious diseases, it is necessary to repeat washing and sterilization each time it is used, and practically significant restrictions have been recognized not only from a sanitary point of view but also to the promotion of labor-saving nursing work. I have.

[0005] For this reason, the present applicant has previously proposed a compression hemostatic belt for improving the above points. Hereinafter, the compression hemostatic belt will be described with reference to FIGS. 5 to 9.

In FIG. 5 and FIG. 6, (1) is a band made of non-stretchable or low-stretchable fiber cloth or the like, and a cloth piece (2) made of a stretchable fiber cloth is sewn at a predetermined position. A pocket (3) is formed. (4) is a hard case made of a synthetic resin formed in a bowl shape, and is accommodated in the pocket (3) of the band (1) with the opening side facing the piece of cloth (2). (5) is a rubber balloon which is inserted into the pocket (3) of the band (1) via the hard case (5) with the fluid supply pipe (7) having the check valve (6) protruding. Is housed. A manually operated pump (8) and a pressure gauge (9) are connected to the fluid supply pipe (7) of the balloon (5), and the pump (8) is viewed while looking at the pressure gauge (9). By operating, a liquid (including a gel-like liquid) or a gas such as air, nitrogen gas or carbon dioxide gas is injected into the balloon (5), and the balloon (5) is inflated.

Next, the procedure for using the compression / hemostatic belt will be described.

As shown in FIG. 7, a gauze (10) is placed on the catheter insertion wound (A) after removing the catheter,
After the pocket (3) of the band (1) accommodating the balloon (5) is placed thereon with the cloth (2) forming the pocket (3) facing the gauze (10) side For example, as shown in FIG. 8, the band (1) is drawn from the groin of the lower limb to the outside of the thigh, the back of the thigh, and the inside of the thigh, and from the crotch to the front of the thigh. And the remaining part is wound one or more times around the body, and the end is wound by using a fixing means such as a non-directional cloth fastener or the like.

When the winding of the band (1) is completed in this way, a manually operated pump (8) and a pressure gauge (9) are connected to the fluid supply pipe (7) of the balloon (5), and the pressure gauge ( 9)
By operating a pump (8) and injecting a liquid or gas into the balloon (5) while observing the balloon, the balloon (5) is inserted into the catheter insertion wound (A) by the rigid case (4) as shown in FIG. While suppressing the expansion to the opposite side of the catheter, expand the catheter insertion wound (A) side,
The band (1) is firmly fixed to the patient at the same time as the catheter insertion wound (A) is pressed through the (0). At this time, by changing the injection amount of the liquid or gas into the balloon (5) by the pump (8) while looking at the pressure gauge (9) according to the patient's body shape, the compression force is freely adjusted, so that the patient And the adjusted compression force is maintained for a long time by the check valve (6).

In addition to the method of winding the band (1) around the body in an X shape as shown in FIG. 8, it may be wound at right angles to the body axis as shown in FIG.

[0011]

By the way, in the above-mentioned compression / hemostatic belt, the rigid case (4) for suppressing the balloon (5) from inflating to the side opposite to the catheter insertion wound (A) is bowl-shaped. Therefore, depending on how to wind the band (1), there is no problem if the band is wound so as to apply the same pressure as a whole, but as shown in FIG. 11, a force is applied to a part of the band (1). When wound in such a way,
When the balloon (5) is inflated by injecting a liquid or gas, as shown in FIG. 12, the lower part of the balloon (5) protrudes from the periphery of the open end of the hard case (4), and the hard race (4) floats. In some cases, it may be deviated from a normal position, and it is difficult to sufficiently stop the bleeding even if bleeding is stopped in such a state. In addition, although it is possible to adjust the compression force, it is impossible to adjust the compression area, and congestion or the like may occur due to compression of an excessively large area.
