Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a puncture point compression device for a distal radial artery. Background Art

[0002] Percutaneous coronary intervention (PCI) via the radial artery has been widely used in the treatment of patients with coronary heart disease due to its advantages of minimal invasiveness, high safety, and short course of treatment. In recent years, the distal radial artery puncture technology has been increasingly used in the field of coronary artery intervention. Compared with the conventional proximal radial artery puncture site, interventional treatment via the distal radial artery approach has the advantages of being more minimally invasive, safe, simple, convenient for postoperative clinical care, low incidence of complications, low radial artery occlusion rate, high patient comfort, and fast recovery. Among them, especially after coronary angiography via the distal radial artery puncture with a 5F thin-walled sheath, the puncture point can be safely released after 2 hours of compression, thereby shortening the postoperative puncture point compression time to further relieve the patient's pain.

[0003] The optional puncture areas for distal radial artery puncture include the Hegu point area and the snuff bottle area, both of which are located on the back of the hand. Specifically, the Hegu point is located between the first and second metacarpal bones, close to the midpoint of the radial side of the second metacarpal bone, and the snuff bottle area is located in the depression between the tendons of the extensor pollicis longus, the extensor pollicis brevis, and the abductor pollicis longus. There are still some urgent problems to be solved in the current distal radial artery puncture technology. First, the conventional postoperative treatment method for distal radial artery puncture is mainly to use gauze self-adhesive elastic bandage to compress the puncture point for hemostasis. However, this compression method without external force assistance often fails to achieve the best hemostasis effect, so the time required for compression may be further shortened. In addition, during the operation, it is usually necessary to bandage after the arterial sheath is removed, but in some cases, the sheath needs to be temporarily retained, which undoubtedly increases the complexity of the bandaging operation, and once the bandage is completed, the sheath may be compressed or restricted. At this time, trying to remove the sheath may cause wound tearing, causing additional pain to the patient.

[0004] In the prior art, a patent document with the announcement number CN219782666U proposes a compression hemostat for distal radial artery puncture, including a compression hemostat body and a pressure sensor, the left and right sides of the compression hemostat body are fixedly connected with a rubber plate, the surface of the rubber plate is penetrated with a long hole, and the inner cavity of the long hole on the right is wrapped and fixedly connected with a fixing belt. This patent has the advantages of pressure detection and anti-falling through the coordinated use of an alarm, a pressure knob, a controller, a pressure relief component, a compression pad, a fixing belt, an adhesive surface, a rubber block, a sheath groove and a pressure sensor.

[0005] Although the patent adopts a fixing belt design to achieve stable fixation of the device position, it still has certain limitations during application. When the puncture point is selected at the distal end of the radial artery, that is, located in the Hegu point area or the snuff bottle area, since these puncture points are all in the back of the hand area, compared with the traditional puncture point located at the proximal end of the radial artery in the wrist area, the fixation of the device is more difficult. The fixing belt of this patent is mainly an annular belt structure, which is more suitable for wearing on the wrist. If the fixing belt is worn on the patient's hand where the puncture point is located, it will gradually slip due to the difference in curvature between the back of the hand and the palm and the daily activities of the patient's hand, thereby affecting the fixation effect of the entire hemostatic device and the final hemostatic effect.

[0006] In addition, on the one hand, there are differences in understanding among technical personnel in this field; on the other hand, the applicant studied a large number of documents and patents when making the present utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present utility model does not have the characteristics of these prior arts. On the contrary, the present utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0007] In view of the shortcomings of the prior art, the present application proposes a puncture point compression device for the distal radial artery, in particular, a compression hemostasis device suitable for puncturing in the snuff bottle area and the Hegu acupoint area, aiming to solve one or more technical problems in the prior art.

[0008] The devices used for compression hemostasis of the distal radial artery in the prior art still use the fixed structure of compression hemostasis of the traditional proximal radial artery puncture. This design does not fully consider the difference between the distal radial artery puncture area and the traditional proximal radial artery puncture area, resulting in poor fixation effect. Specifically, the optional areas for distal radial artery puncture include the Hegu point area and the snuff bottle area. These areas are located at different positions on the back of the patient's hand and require different fixation methods to achieve the best hemostasis effect. However, the existing compression hemostasis devices are relatively limited in their fixation capabilities and cannot flexibly adjust their fixation methods according to different puncture areas.

[0009] In order to improve the positioning and compression effect during the compression hemostasis of the distal radial artery, the prior art has already presented a technical solution for hemostasis positioning and pressing by setting a combined glove and finger sleeve structure. For example, the patent document with the announcement number CN214857149U discloses a distal radial artery compression hemostasis device, including a thumb sleeve for sleeve on the thumb, an index finger sleeve for sleeve on the index finger, and a hemostasis pressing device, the thumb sleeve and the index finger sleeve are connected as a whole to control the posture of the thumb and the index finger and fix the thumb sleeve and the index finger sleeve in the hand position, and the hemostasis pressing device is connected to the thumb sleeve and / or the index finger sleeve and corresponds to the position of the hand base for pressing and hemostasis at the radial artery puncture site. The compression hemostasis device provided by the technical solution can accurately press and position the actual position of the patient's distal radial artery puncture, and can also reasonably adjust the compression force according to the actual situation, so as to achieve a better pressurized hemostasis effect and comfort, shorten the operation time, and facilitate the observation of the puncture point after surgery. However, the hemostatic pressing device in the technical solution is limited only by the specific positions of the thumb sleeve and the index finger sleeve fixing sleeve on the corresponding fingers, and the adjustment position relationship of the thumb sleeve and the index finger sleeve fixing sleeve is limited, and cannot be adaptively adjusted according to the different puncture positions of the patient's base of the thumb, and the actual hemostatic pressing positioning effect is poor. In addition, the position adjustment of the hemostatic pressing device in the technical solution is adjusted by the control rod between the thumb sleeve and the index finger sleeve fixing sleeve. On the one hand, the control rod is connected to the hemostatic pressing device. Therefore, the change of the setting mode of the control rod will directly lead to the change of the setting position of the hemostatic pressing device. At the same time, the length of the control rod and the orientation of the thumb sleeve and the index finger sleeve determine the relative position and posture of the thumb and the index finger. At this time, the setting position of the hemostatic pressing device is affected by the control rod and the adjustment position of the thumb sleeve and the index finger sleeve at the same time. The structural setting mode of the associated influence cannot achieve a stable position adjustment relationship, and the technical solution cannot achieve accurate positioning of the hemostatic pressing device.

[0010] Therefore, in response to the above-mentioned technical problems, the utility model proposes a puncture point compression device for the distal radial artery, which includes a fixing part for keeping the compression device on the distal radial artery and a hemostatic part for compressing and stopping bleeding at the puncture point at the distal radial artery, the fixing part is provided with a wrist cuff and a plurality of finger cuffs connected to the hemostatic part by a connecting rope, the wrist cuff and the finger cuffs can be worn on the patient's wrist and finger respectively, so as to jointly keep the hemostatic part on the Hegu acupoint area or the snuff bottle area where the puncture point on the back of the patient's hand is located, the surface of the wrist cuff and the surface of the finger cuff are both provided with adjustment components for adjusting the distance between the two and the hemostatic part by changing the length of the connecting rope, wherein, according to the different areas where the puncture point is located, the plurality of finger cuffs are worn on different positions of the patient's finger in a manner to improve the fixing effect of the hemostatic part at the puncture point.

[0011] Compared with the above-mentioned prior art, the wrist cuff and finger cuff in the utility model can be connected together to the hemostatic part for compressing and stopping bleeding at the puncture point at the distal radial artery through a connecting rope that can be adjusted in length, and the wearing position of the finger cuff on the patient's finger can be adjusted according to the different areas where the puncture point is located. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to flexibly adjust the distance between the wrist cuff and / or the finger cuff and the hemostatic part according to the specific position of the distal radial artery puncture point, so as to change the direction of the restraining tension provided by different finger cuffs to the hemostatic part, thereby ensuring that the hemostatic part can accurately cover the point that needs to be compressed, and ensuring that the compression and hemostasis effect can reach the best. Specifically, since the two distal radial artery puncture areas of the Hegu point area and the snuff bottle area are located at different positions on the patient's hand, after the medical staff selects different puncture areas to perform the radial artery puncture operation, the fixed position of the compression hemostatic device is also different. The fixed part of the utility model is provided with a wrist cuff and at least two finger cuffs, and the distance between the two and the hemostatic part can be adaptively adjusted by means of an adjustment component, so that after the wrist cuff and the finger cuff are worn and fixed on the patient's wrist and finger, the cooperation of the two can conveniently keep the hemostatic part in the corresponding puncture area. In addition, the finger cuff can also have different wearing positions on the patient's finger according to different puncture areas. Specifically, when the snuff bottle area is selected as the puncture area, since the area where the snuff bottle area is located is roughly located on the extension line of the thumb toward the wrist, at this time, both finger cuffs can be put on the root of the thumb, so that the two finger cuffs can jointly provide the hemostatic part with a restraining tension in the same direction, and the restraining tension can just pass through the central area of ​​the snuff bottle, so that the hemostatic part can be better kept in the snuff bottle area. When the Hegu acupoint area is selected as the puncture area, since the area where the Hegu acupoint area is located is adjacent to the base of the patient's hand, the two finger sleeves can be respectively put on the base of the thumb and index finger, so that the two finger sleeves provide two different directions of restraining tension for the hemostatic part, and the combined force direction of the two restraining tensions just passes through the central area of ​​the Hegu acupoint, so that the hemostatic part can be better maintained in the Hegu acupoint area. It should be noted that the wrist cuff can be fine-tuned according to the position of the finger cuff after the position adjustment. The adjustment of the wrist cuff includes adjusting the distance between it and the hemostatic part, which can be achieved by increasing or shortening the length of the connecting rope between the wrist cuff and the hemostatic part. The adjustment of the wrist cuff also includes adjusting its wearing position, which can be achieved by rotating the wrist cuff on the wrist to ensure that the adjustment components on the wrist cuff correspond to the snuff bottle or the Hegu acupoint respectively.

[0012] According to a preferred embodiment, the connecting rope includes a first connecting rope connected between the hemostatic part and the wrist cuff and a second connecting rope connected between the hemostatic part and a plurality of finger cuffs, wherein the ends of the plurality of second connecting ropes away from the finger cuffs are connected to the same position of the hemostatic part. Compared with the above-mentioned prior art, the sleeve structures at different positions in the utility model can be connected to the hemostatic part together through the connecting rope. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to apply the restraining tension provided by the sleeve structures at different positions to the hemostatic part to provide a stable positioning effect for the puncture hemostasis position. Specifically, the second connecting rope is connected to the same position so that different finger cuffs have the same restraining tension application point relative to the hemostatic part. Such a setting enables each finger cuff to achieve traction on the hemostatic part in different directions by only changing the direction of the restraining tension, thereby keeping the hemostatic part in different puncture areas.

[0013] According to a preferred embodiment, the adjustment component arranged on the surface of the wrist cuff includes a first storage cavity and a first adjustment knob, the first adjustment knob passes through the top surface of the first storage cavity, and the side wall of the first storage cavity is provided with a first storage port, so that the first connecting rope can be connected to one end of the first adjustment knob inside the first storage cavity through the first storage port. The adjustment component arranged on the surface of the finger cuff includes a second storage cavity and a second adjustment knob, the second adjustment knob passes through the side wall of the second storage cavity, and the side wall of the second storage cavity near the hemostasis part is provided with a second storage port, so that the second connecting rope can be connected to one end of the second adjustment knob inside the second storage cavity through the second storage port, wherein the side wall where the second adjustment knob is located is adjacent to the side wall where the second storage port is located. Compared with the above-mentioned prior art, the wrist cuff and the finger cuff in the utility model are both provided with an adjustment component capable of adjusting the length of the connecting rope. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the present invention may include: how to adjust the connection relationship between the sleeve structure and the hemostatic part according to the different positions of the distal radial artery puncture point, so that the hemostatic part can be stably set at the puncture point. Specifically, due to the different positions of the distal radial artery puncture point, the distance between the wrist cuff and / or finger cuff and the hemostatic part will also be different. The medical staff can conveniently pull the connecting rope connected to the finger cuff and / or wrist cuff to contract or stretch through the adjustment component, so as to straighten the connecting rope and achieve precise adjustment of the position of the hemostatic part.

[0014] According to a preferred embodiment, the hemostasis part includes an observation cavity for locating the puncture point, the observation cavity is configured as a hollow cavity without a top and a bottom, a spring is arranged in the concave space of the side wall of the observation cavity, and the bottom of the observation cavity can be blocked by a pressure plate connected to the spring; a rotating shaft is arranged at the top of the side wall of the observation cavity, and the top of the observation cavity can be opened and closed with a cavity cover connected to the rotating shaft. The pressure plate is made of transparent material, so that medical staff can observe the skin on the back of the patient's hand through the pressure plate, so as to accurately determine the position of the patient's puncture point and achieve precise positioning. In addition, when the pressure plate blocks the bottom of the observation cavity, the spring is at a naturally extended length. Such a setting enables the pressure plate to have a tendency to move away from the observation cavity under the action of an external force. In this process, the spring can be stretched and store elastic potential energy synchronously, and drive the pressure plate to restore itself to the position of blocking the bottom of the observation cavity after the external force disappears.

[0015] According to a preferred embodiment, the hemostatic part includes a flexible attachment layer for attaching to the skin on the back of the patient's hand, the flexible attachment layer surrounds the observation cavity, and the first connecting rope and the second connecting rope are connected to the two opposite ends of the observation cavity. The first connecting rope and the second connecting rope are arranged at the two ends of the flexible attachment layer, so that the two can apply restraining tension to the observation cavity from at least two different directions, thereby improving the stability of the hemostatic part covering the puncture point.

[0016] According to a preferred embodiment, a pressure rod is provided through the cavity cover, a pressing head is arranged at one end of the pressure rod close to the pressure plate, and an external thread is arranged on the surface of the pressure rod, which can engage with an internal thread arranged at a portion of the cavity cover penetrated by the pressure rod, so that the rotation of the pressure rod can drive the pressing head to approach or move away from the pressure plate.

[0017] According to a preferred embodiment, a sheath groove is arranged on the bottom surface of the pressure plate away from the pressing head, and the sheath groove extends from the middle of the pressure plate to one of the edges of the pressure plate. The setting of the sheath groove can facilitate the fixation of the sheath position when pressure is applied, and prevent it from being twisted due to the pressure force. At the same time, the sheath can also be pulled out along the sheath groove, avoiding tearing of the wound on the back of the patient's hand.

[0018] According to a preferred embodiment, a cotton yarn layer for absorbing bleeding is attached to the bottom surface of the pressure plate where the sheath groove is located, and the area occupied by the cotton yarn layer is adapted to the bottom surface area of ​​the pressing head. The purpose of this design is that medical staff can determine the puncture point of the patient by observing the area of ​​the pressure plate not covered by the cotton yarn layer, so as to accurately locate the hemostasis part.

[0019] According to a preferred embodiment, the cotton yarn layer is located in the action area when the pressing head presses on the pressure plate, and the cotton yarn layer has a smaller thickness at least at the position corresponding to the sheath groove. Such a setting effectively alleviates the more severe compression of the hemostatic part on the puncture point caused by the presence of the sheath, ensures uniform distribution of force during the entire compression process, and improves the compression hemostasis effect.

DETAILED DESCRIPTION

[0030] The utility model is described in detail below in conjunction with the accompanying drawings.

[0031] Preferably, the utility model relates to a puncture point compression device for the distal radial artery, such as Figure 1 As shown, it includes a fixing portion 100 and a hemostatic portion 200. The fixing portion 100 is used to keep the compression device at the distal radial artery, and the hemostatic portion 200 is used to compress and stop bleeding at the puncture point at the distal radial artery. The fixing portion 100 fixes the position of the compression device (especially the hemostatic portion 200) through a wrist cuff 110 and a plurality of finger cuffs 120. Specifically, the wrist cuff 110 and the finger cuff 120 can be respectively mounted on the patient's wrist and finger, and the two are connected to the hemostatic portion 200 through a connecting rope, thereby transmitting the restraining tension to the hemostatic portion 200. In actual applications, medical staff can determine the position of the hemostatic portion 200 based on the specific position of the distal radial artery puncture point (such as Figure 6 The distance between the wrist cuff 110 and / or the finger cuff 120 and the hemostatic part 200 can be flexibly adjusted by the Hegu acupoint area 300 or the snuff bottle area 400 as shown, thereby ensuring that the hemostatic part 200 can accurately cover the point that needs compression, ensuring that the compression hemostasis effect can achieve the best.

[0032] Preferably, the connecting rope is designed as an elastic rope with a certain elastic force. In order to flexibly adjust the length of the connecting rope, the wrist and the finger are equipped with an adjustment component 130. Figure 1 As shown, the wristband 110 adopts an elastic ring structure, so that it can be easily put on the patient's wrist like wearing a bracelet. The wristband 110 is connected to the hemostasis part 200 by a first connecting rope 131, and the adjustment component 130 provided on the surface of the wristband 110 includes a first storage cavity 132 and a first adjustment knob 134. The first adjustment knob 134 runs through the top surface of the first storage cavity 132, and at the same time, the side wall of the first storage cavity 132 is provided with a first storage port 133 to allow the first connection rope 131 to enter from the port and connect to the end of the first adjustment knob 134 located inside the storage cavity. Such a design enables the first storage cavity 132 to store the first connection rope 131 of excess length, and the end of the first adjustment knob 134 located outside the storage cavity can be rotated by medical staff. By turning the knob, medical staff can easily pull the first connection rope 131 to shrink or extend, thereby realizing accurate adjustment of the position of the compression device.

[0033] Preferably, if Figure 1As shown, the finger sleeve 120 is configured in the form of a finger ring so that it can be worn at the base of the patient's finger. The number of finger sleeves 120 is preferably two, and both finger sleeves 120 are connected to a second connecting rope 135. The ends of the two second connecting ropes 135 away from the finger sleeves 120 are connected to the same position of the hemostasis part 200, which ensures that the action points of the restraining tension of the finger sleeve 120 acting on the hemostasis part 200 through the second connecting rope 135 are the same. The adjustment component 130 provided on the surface of the finger sleeve 120 includes a second receiving cavity 136 and a second adjusting knob 138. The second adjusting knob 138 penetrates the side wall of the second receiving cavity 136, and at the same time, the side wall of the second receiving cavity 136 close to the hemostasis part 200 is provided with a second receiving port 137 to allow the second connecting rope 135 to enter from the port and connect to one end of the second adjusting knob 138 located inside the receiving cavity. The side wall where the second adjusting knob 138 is located is adjacent to the side wall where the second receiving port 137 is located. In actual application, medical personnel can rotate one end of the second adjustment knob 138 located outside the second receiving cavity 136, and pull the second connecting rope 135 to contract or extend, thereby achieving precise adjustment of the position of the compression device. To improve practicality and reliability, the structure of the adjustment assembly 130 of the wrist cuff 110 and the finger cuff 120 can refer to the cable reel (or take-up) structure widely used in the prior art.

[0034] Preferably, when the patient's puncture point is located in the snuff bottle area 400, as Figure 8 As shown, this area is roughly on the extension line of the thumb pointing to the wrist. To ensure effective hemostasis, medical staff can put both finger sleeves 120 on the base of the patient's thumb, and adaptively adjust the length of the second connecting rope 135 to straighten it. This enables the two finger sleeves 120 to work together to provide a restraining tension in the same direction at the same point of action of the hemostasis part 200. This restraining tension can just pass through the center of the snuff bottle area 400, and combined with the restraining tension in the opposite direction provided by the wrist sleeve 110, the deviation of the tension is avoided, thereby ensuring that the hemostasis part 200 can be firmly maintained in the snuff bottle area 400, achieving effective compression hemostasis. When the puncture point is located in the Hegu acupoint area 300, as shown in FIG. Figure 7As shown, since this area is adjacent to the base of the patient's hand, the medical staff can put two finger sleeves 120 on the base of the patient's thumb and index finger respectively, and adaptively adjust the length of the second connecting rope 135 to straighten it. This allows the two finger sleeves 120 to generate two different directions of restraining tension at the same point of action of the hemostatic part 200. The combined force direction of these two tensions can just pass through the Hegu acupoint area 300, and combined with the restraining tension in the opposite direction provided by the wrist cuff 110, the deviation of the tension is avoided. Through this way of wearing and adjusting the finger sleeve 120, the hemostatic part 200 can be more accurately maintained in the Hegu acupoint area 300, ensuring the maximization of the hemostatic effect. In summary, medical staff can flexibly adjust the direction of the restraining tension of the finger sleeve 120 according to the different positions of the puncture point, thereby ensuring that the hemostatic part 200 can be accurately maintained in the required area to achieve effective compression hemostasis.

[0035] Preferably, if Figures 2 to 5 As shown, the hemostasis part 200 includes an observation cavity 207 for locating the puncture point, and the observation cavity 207 is configured as a hollow cavity with the top and the bottom removed, and a part of the side wall thereof is hollowed out, and a spring 211 is arranged in the concave cavity, and the bottom of the observation cavity 207 can be blocked by a pressure plate 201 connected to the spring 211; a rotating shaft 209 is arranged at the top end of the side wall of the observation cavity 207, and the top of the observation cavity 207 is openably and closably covered with a cavity cover 208 connected to the rotating shaft 209, and a snap buckle 210 is provided on the side of the cavity cover 208 away from the rotating shaft 209 to realize the snap connection between the cavity cover 208 and the observation cavity 207. The cavity cover 208 is penetrated by a pressure rod 205, and a pressing head 206 is arranged at one end of the pressure rod 205 close to the pressure plate 201. The surface of the pressure rod 205 is provided with an external thread, which can mesh with the internal thread arranged at the part of the cavity cover 208 penetrated, so that when the medical staff rotates the pressure rod 205, the pressing head 206 can be driven to approach or move away from the pressure plate 201, thereby adjusting the magnitude of the pressure. When the pressure plate 201 blocks the bottom of the observation cavity 207, the spring 211 is at a naturally extended length. Such a setting enables the pressure plate 201 to have a tendency to move away from the observation cavity 207 after being acted upon by the pressing head 206. In this process, the spring 211 can be stretched synchronously and store elastic potential energy, so that after the medical staff rotates the pressure rod 205 and the pressing head 206 releases the pressure on the pressure plate 201, the pressure plate 201 can be driven to restore itself to the position of blocking the bottom of the observation cavity 207.

[0036] Preferably, if Figures 2 to 5As shown, the observation cavity 207 is surrounded by a flexible attachment layer 204 for being attached to the skin of the back of the patient's hand, and the first connecting rope 131 and the second connecting rope 135 can be connected to the two opposite ends of the observation cavity 207. The utility model does not limit the shape of the flexible attachment layer 204, which can be square or elliptical. The flexible attachment layer 204 can use a self-adhesive elastic bandage to ensure softness and fit. It can be stretched and unfolded and maintained in the snuff bottle area 400 or the Hegu acupoint area 300 of the back of the patient's hand. The observation cavity 207 is fixedly connected to the flexible attachment layer 204. When the flexible attachment layer 204 is attached to the snuff bottle area 400 or the Hegu acupoint area 300, the observation cavity 207 also covers the area, and the pressure plate 201 and the pressure rod 205 compress the puncture point inside the hollow cavity of the observation cavity 207, thereby achieving hemostasis. Preferably, the first connecting rope 131 and the second connecting rope 135 are both connected to the side of the observation cavity 207, which means that the ends of the two connecting ropes away from the wrist cuff 110 or the finger cuff 120 are higher relative to the skin surface, higher than the flexible attachment layer 204. This design allows the connecting rope to exert a pulling force on the observation cavity 207 that is always inclined downward. This pulling force not only enhances the fixing effect of the hemostatic part 200, but also further promotes the flexible attachment layer 204 to adhere closely to the skin because of the component force toward the patient's skin. In addition, since the connecting rope is elastic, the patient's hand can freely extend and bend the fingers. In particular, this action does not change the approximate pulling direction of the connecting rope, thereby ensuring that the connecting rope can always provide auxiliary compressive force for the flexible attachment layer 204. At the same time, the elastic force of the elastic rope also helps the patient's hand to perform rehabilitation training, killing two birds with one stone.

[0037] Preferably, if Figure 5 As shown, the bottom surface of the pressure plate 201 away from the pressing head 206 is provided with a sheath groove 202, and the sheath groove 202 extends from the middle of the pressure plate 201 to one of the edges of the pressure plate 201. The setting of the sheath groove 202 can facilitate the fixing of the sheath position when pressure is applied, and prevent it from being twisted due to the pressure force. At the same time, the sheath can also be pulled out along the sheath groove 202 in a directional manner, avoiding wound tearing.

[0038] Preferably, if Figure 5As shown, a layer of cotton yarn layer 203 for absorbing bleeding is attached to the sheath groove 202. The area of ​​this cotton yarn layer 203 matches the bottom surface area of ​​the pressing head 206, ensuring that it is completely covered in the action area where the pressing head 206 applies pressure to the pressure plate 201. The advantage of this design is that since the pressure plate 201 is made of transparent material, when the cavity cover 208 is opened, medical staff can clearly observe the patient's back skin that is not covered by the cotton yarn layer 203 through the pressure plate 201, so as to accurately determine the patient's puncture point and achieve precise positioning. In addition, the cotton yarn layer 203 has a thinner thickness at the position corresponding to the sheath groove 202. This effectively reduces the more severe compression of the hemostasis part 200 on the puncture point caused by the presence of the sheath, ensures the uniform distribution of force during the entire compression process, and improves the effect of compression hemostasis.
