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 to stop bleeding at a catheter-inserted wound after performing arterial catheter inspection or the like.

[0002]

2. Description of the Related Art Recently, arterial catheter examinations have been performed for diagnostic imaging of the heart, cerebral blood vessels and the like.
Cardiac catheterization may be performed by an incision method as a few 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 arteriovenous, and various emporization and preoperative and postoperative tests are performed. In order to prevent bleeding from the catheter insertion wound due to removal of the catheter from the arteriovenous vein, it is necessary to press the catheter insertion wound for a considerably long time. As such a method for hemostasis of pressure on a catheter-inserted wound, conventionally, after manually pressing the catheter-inserted wound for about 15 minutes by a doctor or a nurse, a gauze is applied to the catheter-inserted wound, and a length of 70 cm is placed on the gauze. Apply 3 to 4 cloth bandages with a width of about 5 cm, press the catheter insertion wound on the gauze, and put a sandbag whose weight is adjusted to about 500 to 1000 g on the cloth bandage.
This sandbag was fixed with a cloth plaster so that it would not move, and this fixed state was maintained for 12 to 24 hours.

[0003]

However, in the above-mentioned conventional method, since the gauze applied to the catheter-inserted wound after the catheter is removed and the bandage placed on the gauze are used as a fixing means, the patient is not affected. Squeezing and pain,
Alternatively, there is a problem in that it causes a pruritic sensation and easily causes the occurrence of dermatitis, blisters and the like. Also, even if you are lying on your back, just tilting your body a little makes it easy for the sand to slip
Such displacement of the sandbag causes displacement of the compressed region, resulting in incomplete hemostasis of the wound, resulting in inconvenience such as subcutaneous hematoma.

On the other hand, in order to solve the above-mentioned problems, as a means for compressing and stopping a catheter insertion wound in place of a plaster and a sandbag, JP-A-60-92746 or JP-A-60-1981 has been used.
Japanese Patent Laid-Open No. 39 proposes a belt for compression and hemostasis made of an elastic cloth. However, with these compression and hemostatic belts, the winding method is complicated, and the level of the compression force acting on the catheter insertion wound cannot be visually confirmed, and when the compression force is adjusted, the compression and hemostatic belts are used. Therefore, there is a problem that the pressure load state becomes unstable. Further, since an expensive elastic fiber cloth is used, the manufacturing cost of the compression hemostatic belt rises, and it is difficult to dispose of it despite the hygiene problem of infectious diseases caused by blood adhesion. Therefore, in order to prevent blood infections, it is necessary to repeat washing and sterilization every time it is used, and there are practically significant restrictions not only from a hygienic point of view, but also in promoting labor saving in nursing work. There is.

[0005]

As a means for solving the above problems, the present invention provides a balloon which is inflatable by filling a fluid at a predetermined position of a band made of a non-stretchable or low-stretchable fiber cloth or the like. It was attached by attaching means.

In addition, a hard member is interposed between the balloon and the band to prevent the balloon from expanding toward the side opposite to the hemostatic part.

Further, a non-stretchable reinforcing member is integrally sandwiched on the side of the balloon facing the strip.

Further, the balloon is formed such that the side facing the strip is thick and the side facing the hemostasis part is thin.

Further, a fluid supply pump and a pressure gauge were detachably connected to the balloon through a check valve.

[0010]

By filling a balloon attached to a predetermined position of the band with an appropriate fluid, the balloon is inflated to press the hemostatic portion.

By interposing the hard member between the balloon and the band, the balloon is inflated only to the hemostatic portion while preventing the balloon from inflating to the side opposite to the hemostatic portion.

By sandwiching the non-stretchable reinforcing member on the side of the balloon opposite to the band, the balloon is inflated only to the hemostatic portion while preventing expansion to the side opposite to the hemostatic portion without using a rigid member. ..

By forming the balloon so that the side facing the band is thick and the side facing the hemostatic part is thin, the balloon is inflated to the side opposite to the hemostatic part without using a rigid member. Inflate only to the hemostatic part while preventing.

Since the pump for supplying fluid and the pressure gauge are detachably connected to the balloon via the check valve, the pump is operated while observing the pressure gauge to fill the balloon with fluid and press the hemostatic portion. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a description of the embodiments of the present invention shown in the drawings.

FIGS. 1 and 2 show a first embodiment of the present invention, in which (1) is a band made of a non-stretchable or low-stretchable fiber cloth, which is stretchable at a predetermined position. The pocket cloth (2) is sewn to form the pocket (3). (4) is a hard case as a rigid member made of a synthetic resin or the like formed in a bowl shape, and is housed in the pocket (3) of the band (1) with the opening side facing the pocket cloth (2). ing. (5) is an appropriate fluid (air, nitrogen gas,
A fluid supply pipe having a check valve (6) in a pocket (3) of a band (1), which is a rubber balloon that can be expanded by filling a gas such as carbon dioxide gas or a liquid including gel). The (7) is housed in the hard case (4) in a state of being projected to the outside. The fluid supply pipe (7) of the balloon (5) has, for example, a manually operated pump (8).
And a pressure gauge (9) are connected, and by operating the pump (8) while looking at the pressure gauge (9), the fluid is filled into the balloon (5) through the fluid supply pipe (7). As a result, the balloon (5) is inflated.

Next, a description will be given of how to use the compression / hemostatic belt of the present invention.

As shown in FIG. 3, gauze (10) is placed on the catheter insertion wound (A) after the catheter is removed,
Pocket (3) on which the balloon (5) is housed
After placing the pocket piece (2) of the device facing the gauze (10) side, for example, as shown in FIG. 4, the band (1) is wound around the waist of the patient one or more times and the end thereof is wound. It is wrapped around the patient's body by locking the part using a fixing means such as a plaster.

When the winding of the strip (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 ( By operating the pump (8) while observing 9) to fill the balloon (5) with fluid, the balloon (5) is inserted into the catheter case (A) by the hard case (4) as shown in FIG. The catheter-inserted wound (A) is expanded through the gauze (10) while suppressing the expansion to the opposite side of the catheter-inserted wound (A) side, and at the same time,
The band (1) is firmly fixed to the patient.

When the fluid for inflating the balloon (5) is changed to a liquid, the balloon (5) and the check valve (6) attached to the balloon (5) are less likely to leak than the gas, and even if they leak, the strip ( It is easy to see 1) etc. getting wet and it is easy to keep the pressing force constant.

As described above, the compression / hemostatic belt presses the catheter insertion wound (A) by utilizing the expansion of the balloon (5), so that only the catheter insertion wound (A) can be pressed. A feeling of pressure hardly propagates to other parts. Moreover, by operating the pump (8) while looking at the pressure gauge (9) according to the body shape of the patient, the filling amount of the fluid in the balloon (5) is adjusted and added to the catheter insertion wound (A). By freely selecting the magnitude of the compression force, it is possible to perform compression hemostasis suitable for the patient, and to maintain the selected compression force for a long time by the check valve (6). It is also possible to employ automatic compression force control by a computer as needed. Furthermore, since the non-stretchable or low stretchable fiber cloth is used for the strip (1),
It is possible to avoid the occurrence of tightness, pain, or pruritus, and to prevent dermatitis and blisters.

By the way, in the first embodiment, the hard case (4) prevents the balloon (5) from expanding to the opposite side of the catheter insertion wound (A).
When the band (1) is wrapped around the body, a hard case (4)
May touch the body and cause discomfort. Next, a book designed to prevent the balloon (5) from inflating to the opposite side of the catheter insertion wound (A) without using the hard case (4). A second embodiment and a third embodiment of the invention will be described.

First, in the second embodiment, the balloon (5) in the structure of the first embodiment has a structure as shown in FIG. That is, on the side of the balloon (5) facing the band (1), that is, on the outer side (5a), cloth, net, film, PET,
A sheet-shaped non-stretchable reinforcing member (11) made of paper or the like is inserted. The non-stretchable reinforcing member (11) is used for manufacturing the balloon (5) at the outer side (5a) of the balloon (5).
It is sandwiched integrally with. In short, for example, when the balloon (5) is manufactured by a latex dipping method, the balloon mold is once dipped in latex, and then the non-stretchable reinforcement is applied to one surface forming the outer side (5a) of the balloon mold (5). The member (11) is attached and the non-stretchable reinforcing member (11) is attached.
Non-stretchable reinforcing member (11) by immersing only one side of the balloon type with which it has been stuck in latex again for vulcanization
Is integrally sandwiched on the outer side (5a) of the balloon (5).

In this second embodiment, even if the balloon (5) is filled with a fluid, as shown in FIG. 7, the balloon (5) is
The outer side (5a) is not expanded by the non-stretchable reinforcing member (11), and conversely, only the side facing the catheter insertion wound (A), that is, the affected part side (5b) is greatly expanded. Therefore, as shown in FIG. 8, the balloon (5) is prevented from inflating to the opposite side of the catheter insertion wound (A), and is inflated only to the catheter insertion wound (A) side and passed through the gauze (10). The catheter-inserted wound (A) can be compressed with sufficient compression force.

Next, in the third embodiment, the balloon (5) in the construction of the first embodiment has a structure as shown in FIG. That is, the thickness of the balloon (5) is the affected part side (5b)
Is thin, and the outer side (5a) is formed thick with respect to the affected part side (5b) at a constant ratio. The thickness of the affected part side (5b) is about 0.1 mm to 2.0 mm. If it is thinner than this, there is a problem such as pinholes or aging during storage and transportation, or if it is thick, fill it with fluid. There is a problem that the compressive force decreases with respect to the internal pressure. Further, the thickness of the outer side (5a) is about 0.5 mm to 5.0 mm, and the reason in this case is the same as the above. If it is particularly thick, it causes a problem in the manufacturing method.

In the third embodiment, even if the fluid is filled in the balloon (5), as shown in FIG.
The outer side (5a) has a large thickness and does not expand so much, while the affected part side (5b) has a small thickness and expands greatly. Therefore, as shown in FIG. 11, the balloon (5) is prevented from inflating to the side opposite to the catheter insertion wound (A), and is inflated only to the catheter insertion wound (A) side so that the gauze (10).
The catheter-inserted wound (A) can be pressed with a sufficient pressing force via the.

As described above, the second and third embodiments do not use the hard case (4) as in the first embodiment, so that when the first embodiment is wrapped around the body, The uncomfortable feeling caused by the hard case (4) touching the body is eliminated, and the cost when performing disposable is reduced, and it can be provided at a lower cost.

Although a fiber cloth is used for the band (1) in the above embodiment, other than this fiber cloth, a material made of non-stretchable or low stretchable material such as leather or film may be used. Although the stretchable fiber cloth is used as the pocket cloth (2), it is also possible to use a stretchable material other than this stretchable cloth such as rubber.

[0029]

According to the present invention, since a non-stretchable or low-stretchable fiber cloth or the like is used for the band, the occurrence of bulging feeling, pain, or pruritus is avoided, and dermatitis or dermatitis occurs. Blisters are also prevented. Since a balloon that can be inflated by using a fluid as the compression means is used, the compression range is narrowed, and the hemostatic function that compresses only the catheter insertion wound is secured, while the feeling of compression is almost propagated to other parts. A state that does not occur is created. In addition, since the pressurizing structure is configured by connecting the pump and the pressure gauge via the check valve to the balloon that is inflatable by being filled with fluid, the magnitude of the compressive force to be applied to the catheter insertion wound. Can be freely selected, and the adjusted compression force can be maintained for a long time by the check valve. In addition, since the balloon that can be inflated by filling the fluid is pressed and fixed at the same time, it has good operability.Because it does not require sandbags, it is compact and easy to carry. Provided. Furthermore, the components other than the pump and pressure gauge are significantly cheaper than the conventional products, so they can be disposable once, and attention should be paid to the improvement of hygiene management and the promotion of labor saving. The effect is demonstrated.

Further, according to the present invention, since the balloon whose outer side is not inflated so much and only the affected part side is greatly inflated is used, the hard case becomes unnecessary, and the compression means is only the flexible balloon. There is no problem even when wrapped around the body, and the cost when considering the disposable is reduced, and it can be provided at a lower cost.
