Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure hemostasis for safely carrying out hemostasis of a living body puncture part after removal of an insertion catheter used for medical diagnosis, without the need for a doctor's hand. It relates to the device.

[0002]

2. Description of the Related Art In order to diagnose the heart and blood vessels, it is often practiced to perform X-ray imaging by injecting a contrast medium with a catheter and performing a usual medical diagnosis. At this time, in order to stop bleeding from the biopsy site, the doctor manually
Hemostasis is performed while compressing the site for minutes and sometimes more. Further, if the position of the skin puncture and the position of the blood vessel puncture are misaligned and only the skin puncture is pressed, subcutaneous hematoma may occur, which may adversely affect the patient. Further, in a patient having a tendency to bleed, it may be necessary to continue pressing even after hemostasis is once performed, and there is a problem that the physical and time burden of the doctor during this period is extremely large. Several proposals have already been made to solve such problems. For example, a method of pressing the living body puncturing portion with a hard object (hard pressing type), a method of pressing the living body puncturing portion with a single bag, and the like have been proposed, but none have come into widespread use. In the method of compressing the biopsy puncture site with a hard object, the target tissue does not have a flat structure, so the pressure is unevenly applied, and many pressures are applied to other tissues such as bone before sufficient pressure is applied to the blood vessel. Causes pain to the patient and cannot measure the pressure applied to the blood vessel, so it is not possible to know whether the pressure is appropriate or not, and if the pressure is too strong, there is a risk of causing blood vessel thrombosis. However, if it is too weak, it has the drawback of causing subcutaneous bleeding. Also, a method of pressing the living body puncture part with a single bag (plastic bellows type or rubber bag / belt type)
Is inspired by an air bag called Manchette, which is widely used in blood pressure measuring instruments, but it is a method of sending air into a soft bag and pressing the living puncture part with its expanding force. Although it has become possible to grasp the pressure applied to the to some extent, this method has the following drawbacks. That is, the pressure applied to the artery may not be accurately grasped. Generally, when the bag is expanded, a gas having a volume larger than the peculiar volume of the bag is fed, the surface of the bag becomes tight, and the internal pressure becomes higher than the external pressure. For this reason, in this method of compressing the blood vessel by the bulge of the bag, the bag is overexpanded before the effective pressure on the blood vessel is sufficiently reached, and the internal pressure of the bag rises from midway irrespective of the surrounding pressure. The situation easily occurs. In the case of an obese patient or the like, although the pressure inside the bag has reached a sufficient value, the pressure is not transmitted to the blood vessel, so that it often happens that the patient bleeds after the catheter is removed, and it is difficult to cope with it. Further, in the above-described back compression method, the work of gradually reducing the pressure still remains, and the doctor and the nurse cannot leave the site, and the labor saving aim is not achieved so much. Since there is no problem in the effectiveness and safety of stopping bleeding with fingers by human power, there is no need for such a device unless labor saving is sufficiently achieved, and the existence value is significantly reduced. Further, there is a risk of causing damage to peripheral tissues due to long-term compression and inducing intravascular thrombosis. The decompression of the bag must be performed frequently by a doctor or a nurse while measuring the time, and therefore it is easy to induce mistakes such as forgetting or delaying the work. as a result,
Frequently unnecessarily long-time compression causes a risk of ischemia of peripheral tissues and intravascular thrombus formation. Furthermore, in the above-described device for compressing and bleeding a living body puncture portion, it is difficult to adjust the hemostatic pressure while observing the state of the living body puncture portion directly with the naked eye, and it is possible to apply an appropriate pressure only to the living body puncture portion. If you try not to press the living body puncture part and try to stop the bleeding without fail, a wide area will be pressed, and there is a risk of insufficient blood flow in the living tissue, which may cause damage. If only one is pressed, the compression / hemostatic device may be displaced from the living body puncture part, leading to an accident. Further, since such a hemostatic device is contaminated by blood, it is preferable that the hemostatic device is disposed of in a single use without being reused, and therefore, without using expensive materials and devices. Must be manufactured.

DISCLOSURE OF THE INVENTION The present invention uses a device to perform pressure hemostasis of a living body puncture portion, which has been conventionally performed by a doctor or the like, and presses only the living body puncture portion, thereby surrounding the living body. The object of the present invention is to provide a compression hemostasis device that does not damage the tissue due to insufficient blood flow and that does not cause displacement of the compression site even if only the living body puncture part is compressed.

[0004]

As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention have fixed and pressed a transparent, non-stretchable pressure bag with a support having a see-through window. For example, while observing the state of the living body puncturing portion, it was found that hemostasis can be performed reliably and safely without adversely affecting living tissues other than the living body puncturing portion, and the present invention is completed based on this finding. Came to. That is, the present invention includes (1) a pressurizing bag for pressing the living body puncturing part and a supporter for fixing and pressing the pressurizing bag, and the supporter is provided with a see-through window in the pressurizing bag fixing and pressing part. The present invention provides a compression hemostatic device characterized in that Furthermore, as a preferred embodiment of the present invention, (2) the pressure bag according to item (1), wherein the pressure bag is made of a substantially transparent and non-stretchable material, (3) the central side of the living body puncture part. (1) or (2) with an auxiliary hemostatic bag that compresses the entire circumference of the
(4) A supporter provided with a see-through window that does not apply pressure to a portion other than the direction of compression hemostasis and the direction opposite thereto when performing pressure hemostasis on the living body puncturing section by (4) a pressure bag. The compression hemostasis device according to any one of (1) to (3), and (5) the compression bag according to any one of (1) to (4) above, wherein the pressure bag comprises a pressure sensing bag and a compression bag. A device, (6) pressurizing means communicating with the pressurizing bag,
First (1) having a pressure release means and a residual pressure control means
The compression hemostatic device according to the item (5) can be mentioned.

In the compression / hemostatic device of the present invention, the pressure bag used for hemostasis is fixedly compressed by a supporter having a see-through window. The supporter has a frame structure that presses the pressure bag, and has a window-shaped space portion or a transparent portion inside the frame. The shape of the window-shaped space portion or the transparent portion is not particularly limited as long as it can press and fix the pressure bag,
A circular shape, a quadrangular shape, a hexagonal shape, or the like can be arbitrarily selected, and a crosspiece structure can be provided in a window-shaped space portion or a transparent portion as needed. The material forming the transparent portion of the see-through window is substantially transparent, and can be used without particular limitation as long as the state of the living body puncture portion can be observed with the naked eye through the see-through window and the pressure back, Examples of such a material include glass, acrylic resin, polycarbonate resin, polystyrene resin and the like. When the supporter has a window-shaped space, the pressure bag expands by sending compressed air, compresses the living body puncture part, and swells and is fixed in the window-shaped space. The position does not shift. When the support has a window-shaped transparent portion, the transparent portion has a concave structure, or the transparent portion is provided with irregularities so that the expanding pressure bag swells into the concave structure and is fixed, or It is preferable that the pressure bag expanded by the unevenness of the transparent portion is fixed and the position thereof is prevented from shifting. When the pressure bag is relatively small, the see-through window may be a single space portion, but when the pressure bag is relatively large, it preferably has a crosspiece structure. Examples of the transparent window of the support used in the pressure hemostatic device of the present invention include a window having a circular space portion, a window having a circular space portion having a Y-shaped rail structure, and a cross-shaped rail structure. Examples thereof include a window having a square space provided. FIG. 1 is a cross-sectional view of an embodiment of the compression hemostatic device of the present invention during use. When the pressure bag 3 is inserted between the lower limb 1 having the living body puncture part and the fenestrated frame 2 and compressed air is sent to expand the pressure bag,
The pressure bag presses the living body puncture part underneath to stop bleeding,
Its upper part bulges into the see-through window of the support and its position is fixed. In this figure, since the supporter has the crosspiece structure 4, the pressure bag is more reliably fixed. In the compression hemostatic device of the present invention, the pressure bag is made of a substantially transparent and non-stretchable material. The material that makes up the pressure bag is transparent and non-stretchable, approximately 500 mmHg
It can be used without any limitation as long as it can seal the periphery to withstand the pressure up to
For example, soft vinyl chloride film, polyvinylidene chloride film, polyester film, polypropylene film,
Examples thereof include polysulfone film. Since the pressure bag is discarded every time it is used, it needs to be an inexpensive material, has suitable non-stretchability, and is easy to process, and thus a soft vinyl chloride film is particularly preferable. The pressure bag used in the compression / hemostatic device of the present invention is made of a substantially transparent material so that the state of the living body puncture part can be visually observed through the support and the pressure bag, and the pressure of the pressure bag can be adjusted. The treatment can be performed while taking necessary treatments such as. In the method of bleeding by pressing the living body puncturing portion directly with the fingers of a doctor or the like, the pressure applied to the living body puncturing portion must rely on the sense of the doctor or the like, which requires skill. If the pressure hemostatic device of the present invention is used, the pressure of the pressurizing bag is quantitatively displayed by the pressure gauge, and the pressure per unit area applied to the living body puncture part is equal to the pressure in the pressurizing bag, so that it can be easily known. Since the state of the living body puncture portion can be observed with the naked eye, hemostasis of the living body puncture portion can be performed very easily. The pressure bag used in the compression hemostatic device of the present invention is preferably composed of a non-stretchable material, and the elastic modulus of the material forming the pressure bag is low, and when the material expands and expands by blowing compressed air. However, it is not preferable because the pressure necessary to press the living body puncture portion cannot be applied, or the expanded and deformed pressure bag may be displaced from the window frame. In the compression hemostatic device of the present invention, since the compression of the biopsy puncture portion is performed by the pressure back, unlike the method of compressing the biopsy puncture portion using a hard compression element, the compression should be performed uniformly regardless of the shape of the tissue. You can

The pressure bag of the compression / hemostatic device of the present invention comprises a pressure-sensing bag made of a non-stretchable material containing a fluid and a compression bag made of a non-stretchable material laminated thereon. It is possible to use a structure having a structure for compressing a blood vessel by sending compressed air to the compression bag. The pressure-sensing bag and the compression bag may be bonded and integrated, or may be individually configured, and can be used properly depending on the application.
Since the pressure-sensitive bag is filled with a volume of fluid that does not exceed its volume and is made of a non-stretchable material, the pressure inside is equal to the pressure compressed by the bag, and the pressure transmitted to the blood vessel can be accurately monitored. can do. Also,
By separately using the pressure sensing bag and the compression bag, the pressure applied to the blood vessel can be accurately grasped by the pressure sensing bag, which improves safety and convenience. Furthermore, only the pressure-sensing bag directly touches the affected area, and only the pressure-sensing bag needs to be disposable, and the running cost can be reduced. Comparing the compression hemostasis device of the present invention with a manchette which is a band-like structure which has a conventionally used lumen and is wound around the upper and lower limbs and used, the manchette is wrapped around the entire circumference of the upper and lower limbs, and therefore the living body puncture portion is used. Other parts are also pressed, and a wide part of the tissue of the living body is pressed and blood flow is inhibited, whereas the compression hemostatic device of the present invention is stably fixed by the supporter, and therefore the living body puncture part and its Only the narrow part in the opposite direction is compressed, and the tissue in the direction perpendicular to the compression direction does not receive pressure and blood flow is maintained, so there is no risk of venous thrombosis and unnecessary tissue There is no danger of damaging parts.

In the compression / hemostatic device of the present invention, a support for fixing and compressing the pressure bag is used. The support comprises a plate or frame with a see-through window and support means for fixing this. The plate with a window or the frame may have any shape as long as it has the window as described above, and may be curved so as to match the shape of the upper limb or the lower limb. The shape of the supporting means is not limited, and the shape can be freely selected as long as it can support the windowed plate or the windowed frame at a fixed position. Figure 2
[Fig. 3] is a perspective view showing an aspect of a supporter used in the compression hemostatic device of the present invention. FIG. 2 (a) shows a supporter composed of a U-shaped support means having several slits 5 in the side wall and a plate with a transparent window. Place it on top, stack a pressure bag on the living body puncture part, pass a plate with a window through a slit at an appropriate position, and inflate the pressure back bag with compressed air to press the living body puncture part and stop bleeding. . FIG. 2 (b) shows a supporter including two plates 6 and 7 fixed by a support column 8 and a support means having a compression rod 10 which is moved up and down by rotation of a handle 9 on the upper plate and a plate with a window. Is. A plate with a window or a window frame is attached to the tip of the compression rod, the upper and lower limbs are placed on this support at the position of the biopsy part, and a pressure bag is overlaid on the biopsy part, then the handle is rotated. The fenestrated frame or the windowed plate is lowered to an appropriate position, and compressed air is introduced into the pressure bag to inflate it to press the living body puncture part and stop the bleeding. Figure 2 (c) shows
A supporter having velcro tapes 11 attached to both sides of a rectangular window frame having a circular window, which can be attached by pressing and stacking, and after stacking a pressure bag on the living body puncture parts of the upper and lower limbs. , Place the window frame of the support on the pressure bag, and fix the support to the upper and lower limbs with Velcro. Then, the pressure bag is inflated with compressed air to press the living body puncture portion and stop the bleeding. Even when this support is used, if the length between both sides of the support attached with the Velcro is sufficiently longer than the diameter of the upper and lower limbs, the part of the upper and lower limbs on which pressure is applied is located on the biological puncture part and the opposite side. However, since there is no pressure in the lateral direction, it does not totally stop the blood flow. Figure 2
(d) is a supporter including a cylindrical support frame 12 and a plate having a see-through window that can be fitted and is inserted inside the support frame.
In the figure, the plate with the transparent window in the cylinder is indicated by the dotted line. After stacking a pressure bag on the living body puncture part of the upper limb or lower limb, place the rectangular plate with a transparent window of this support on the pressure bag, and the support frame on the upper limb or lower limb with the pressure bag and the windowed plate. Pass through. Then, the pressure bag is inflated with compressed air or the like to fit the windowed plate into the tubular support frame, and the pressure bag can press the living body puncture portion to stop bleeding. By forming a tubular support frame of a transparent material in the present supporter, the pressed state of the living body puncture portion can be confirmed. Further, by using the windowed plate rotated by 90 degrees, it can be applied in correspondence with the difference in the thickness of the upper limb or the lower limb. The pressure hemostatic device of the present invention can include an auxiliary hemostatic bag that compresses the entire circumference of the central side of the upper and lower limbs, in addition to the hemostatic effect by the pressure bag. The compression hemostatic device of the present invention having the auxiliary hemostatic bag can be suitably used particularly for the upper limb. FIG. 3 is a perspective view of one embodiment of a compression hemostatic device including the auxiliary hemostatic bag of the present invention. In this figure, the pressure bag 3 is overlaid on the living body puncture part of the upper limb and is fixed and compressed by the supporter having the structure of FIG. 2 (c). Further, an auxiliary hemostatic bag 13 that squeezes the entire circumference of the upper limb is wound around the central side of the upper limb. A tube 14 for sending compressed air is connected to the pressure bag 3 and the auxiliary hemostatic bag 13, and two tubes are further connected to a compressed air source via a three-way stopcock 15.
For the upper limbs, using a large pressure bag for the lower limbs,
The patient suffers a great deal of pressure. However, if the pressure bag is made small, bleeding may occur even if the fixing place is slightly displaced, and when bleeding, it is very difficult to fix again. Therefore, these problems are solved by using the compression hemostatic device having the auxiliary hemostatic bag of the present invention. That is, when bleeding occurs during pressing, the auxiliary hemostatic bag is pressed to urgently stop the bleeding, while the pressure of the pressing bag for hemostasis of the living body puncture part is adjusted or the position of the pressing bag is changed. Can be re-fixed. In the upper limbs, the artery on the central side is at a deep position, so pressure hemostasis by hand is difficult, and if the pressure back of the biopsy puncture is bleeding due to being out of the proper position, reattach the pressure back. Bleeding in between is a serious problem, and provision of an auxiliary hemostatic bag on the central side can cope with such an emergency.

The compression hemostatic device of the present invention preferably has a pressure bag and a pressure means, a pressure release means and a residual pressure control means communicating with the pressure bag. The pressure bag is connected to the compressed air source by a tube, and the pressure release means and the residual pressure control means are connected to the tube.
In addition, the tube may have a pressure gauge, a cock, and
A known jig such as a check valve or a connector can be attached to facilitate the hemostasis operation. The residual pressure adjusting means used in the pressure hemostatic device of the present invention comprises a pressure adjusting bag or a pressure adjusting valve to adjust the hemostatic pressure at an appropriate speed that follows the appropriate pressure required for hemostasis predicted based on clinical diagnostic findings. Is continuously lowered, and the pressure of the pressurizing bag is controlled by connecting with the pressure adjusting bag or the pressure adjusting valve so as to continuously reach a predetermined final residual pressure at which the blood flow necessary for the living tissue flows. By controlling the decrease process of the pressure of the pressurizing bag in this way, the biological tissue is not damaged by applying excessive pressure for hemostasis, and the hemostatic ability of the biological tissue itself is restored. Complete control can be provided to maintain the pressure required for hemostasis. By automatically performing the decompression in this way, labor saving is achieved, and the risk of unnecessarily long ischemia time due to the delay or forgetting of the decompression work is avoided. Further, by pressing the pressure-sensing bag in advance, it is possible to set such that a certain amount of pressure remains in the affected area even after all the air in the compression bag has been exhausted. In the compression hemostatic device of the present invention, the pressurizing means can be used without particular limitation as long as it applies air pressure to the pressurizing bag. For example, a normal spherical rubber ball made of rubber, rubberized cloth or the like. A device that can be pressurized by palm pressure, such as an air pump, is preferable in terms of easy handling. Furthermore, most of the pressure necessary for compressing the living body puncture part can be applied with a compressed air source, and the pressure can be finely adjusted with a rubber ball air pump or the like. In the pressure hemostatic device of the present invention,
As the pressure releasing means, a known jig can be used without particular limitation, and for example, a cock, a pinch cock, a valve or the like can be used.

The compression / hemostatic device of the present invention can be used while observing the bleeding and hemostasis of the living body puncture portion with the naked eye without damaging the living tissue around the living body puncture portion. , For example, after applying 120 ± 20 mmHg or more, hemostasis of the living body itself due to blood coagulation of the living body puncture part,
Depending on the degree of recovery of the ability of the occlusion, the pressure may be set based on clinical data at a desirable setting, eg 50
Automatically continuously lowers to mmHg within a predetermined time,
Furthermore, if necessary, a predetermined pressing value can be maintained. As a result, the circulation of blood is stopped or restricted by an unnecessary hemostatic pressure, and damage to living tissue can be suppressed to a minimum. In the pressure hemostatic device of the present invention, this pressure control can be performed by the residual pressure control means. The residual pressure control means used in the compression / hemostatic device of the present invention brings the pressure of the pressurizing bag to a certain low pressure at a preset time, for example, 20-6.
It is a means for continuously and gradually lowering during 0 minutes, for example, a method of combining a pressure adjusting valve and a fine adjusting cock, or connecting a pressure bag to a residual pressure adjusting bag with a ventilation pipe,
A method of providing an orifice, a fine adjustment cock, or the like in the intermediate passage can be used. In the pressure hemostatic device of the present invention, when a pressure adjusting valve is used as the residual pressure adjusting means, the object can be achieved by simply opening the cock leading to the pressure adjusting valve whose release pressure is set to a predetermined pressure. it can. As the pressure adjusting valve, any known pressure adjusting valve can be used without limitation as long as the gas leaks at the set constant pressure and the system can be maintained at the set pressure. It is preferable to use a valve that is sealed with rubber or the like that has a slight leakage of air when the pressure exceeds the rubber elastic force. In the compression hemostatic device of the present invention, when a pressure adjusting bag is used as the residual pressure adjusting means, the residual pressure can be adjusted by opening the ventilation pipe between the pressurizing bag and the residual pressure adjusting bag. In this case, a method of providing a fine adjustment cock and an orifice having an appropriate diameter in parallel in the intermediate passage between the pressurizing bag and the residual pressure adjusting bag is preferable because the speed of pressure decrease can be continuously and precisely controlled. In this method, the fine adjustment cock can be used to increase the pressure reduction rate, and the fine adjustment cock can be closed to reduce the pressure by the orifice when a gradual pressure reduction rate is required. In this case, as the orifice passage,
By arranging two or more kinds of orifices having different diameters in parallel, it is possible to variously adjust the speed until the final residual pressure is reached. For example, if two orifices having different diameters are used, it is possible to select three types of lowering speeds when opening one of each of them and when opening two of them. If three or more orifices are used, it is possible to select a higher reduction rate. If the fine adjustment needle valve that can adjust the flow rate more accurately than the fine adjustment cock is used instead of the method using the orifice, the rate of pressure decrease can be arbitrarily adjusted. The final residual pressure of the compression hemostatic device of the present invention can be set to the lowest pressure required by the doctor for hemostasis. The minimum residual pressure can be controlled by adjusting the release pressure of the pressure regulating valve and adjusting the initial pressure or the initial air volume of the pressure regulating bag.
