Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an arm supporting device for coronary angiography. Background Art

[0002] Coronary angiography is a simple, effective and non-invasive method for diagnosing and predicting early coronary artery disease. First, the patient must be given local anesthesia, usually in the groin or wrist, and then the artery is punctured. The catheter is carefully pushed along the blood vessel through the puncture point. Under the guidance of X-ray fluoroscopy, the catheter is guided along the aorta to the opening of the coronary artery. After that, contrast agent is injected from the catheter. The contrast agent will fill the blood vessels as the blood flows in the coronary artery. At the same time, X-rays are taken quickly to clearly show the shape, course, and whether there is stenosis or blockage of the coronary artery. Finally, the catheter is carefully withdrawn and appropriate hemostasis is performed on the puncture site.

[0003] At present, coronary angiography is still an important means of diagnosing coronary heart disease. After performing coronary angiography on adolescents, it is necessary to press on the puncture site of the patient to stop bleeding. Generally, a watch-like pressurized hemostat is used to brake the patient's puncture site for 4-6 hours, and the doctor needs to be assisted in loosening the pressurized hemostat on the wound every two hours. However, due to the lively and active nature of adolescent patients, they may unconsciously twist the wrist that needs to be braked, causing the puncture site to bleed again. Usually, after stopping bleeding at the patient's puncture site, medical staff will remind the accompanying personnel to strengthen supervision of the patient to avoid this situation. However, it is impossible for the accompanying personnel to continuously supervise the patient during the entire braking period. Therefore, the present invention provides an arm support device for coronary angiography surgery to meet the needs. Summary of the invention

[0047] like Figures 1 to 17As shown, an embodiment of the present invention provides an arm support device for coronary angiography surgery, including a movable buckle 1, which is screwed to a T-shaped support plate 2 through a nut, two support plates 201 are fixedly connected to the outer wall of the top of the T-shaped support plate 2 near one end, one end of the two support plates 201 are fixedly connected to an upper arm support plate 202, a first buckle 204 is fixedly connected to the middle position of the top outer wall of the T-shaped support plate 2, two fixed plates 203 are fixedly connected to the outer wall of the top of the T-shaped support plate 2 near the other end, and a sliding groove is provided on the fixed plate 203; specifically, one end of the movable buckle 1 is screwed to the bed frame on one side of the bed through a nut, and the other end of the movable buckle 1 is screwed to one end of the T-shaped support plate 2 through a nut. The movable buckle 1 is disclosed in the prior art and will not be described in detail.

[0048] The T-shaped support plate 2 is a "T"-shaped plastic plate. Two support plates 201 are symmetrically fixedly connected to the outer walls on both sides of the top of the T-shaped support plate 2 near one end of the movable buckle 1. The support plate 201 is a square plastic plate. The other ends of the two support plates 201 are fixedly connected to the outer wall of the upper arm support plate 202. The upper arm support plate 202 is an arc-shaped plastic plate with ventilation holes. When supporting the patient's upper arm, the air permeability of the contact surface of the upper arm support plate 202 can be maintained, and the patient's comfort can be maintained during long-term braking. The first buckle 204 is fixedly connected to the T-shaped support plate 201. In the middle position of the top outer wall of the plate 2, the first buckle 204 is composed of two parts: a square plastic plate and a "C"-shaped arc-shaped plastic plate, wherein an outward-expanding arc is set at the opening of the "C"-shaped arc-shaped plastic plate of the first buckle 204, which can facilitate the snap-in connection. The two fixed plates 203 are symmetrically fixedly connected to the outer walls on both sides of the top of the T-shaped support plate 2 away from the end of the movable buckle 1. The fixed plate 203 is a square plastic plate, and a sliding groove is opened on the outer wall of the fixed plate 203 near the top, and the sliding groove is composed of a groove body composed of a rectangle and a semicircle.

[0049] The arm support device also includes a limiting component, which is used to limit the patient's puncture site during the pressurized hemostasis process. The limiting component is connected to the first buckle 204 and the fixing plate 203 respectively. By setting the limiting component, the patient's puncture site can be limited during the pressurized hemostasis process. For adolescent patients who are lively and active by nature, during the arm braking period, they may unconsciously twist the wrist that needs to be braked, causing the puncture site to bleed again. The setting of the limiting component can not only limit the patient's wrist, but also improve the comfort of the patient's arm during the braking period.

[0050] like Figures 1 to 5As shown, the limiting assembly includes a clamping column 305 clamped on the inner wall of the first clamp 204, one end of the clamping column 305 is fixedly connected to the forearm support frame 3, five arc-shaped elastic plates 301 are fixedly connected to the inner wall of the forearm support frame 3, two C-shaped elastic plates 302 are fixedly connected to the outer wall of one end of the forearm support frame 3, and one end of the C-shaped elastic plate 302 is fixedly connected to the second clamp 303. Specifically, the clamping column 305 included in the limiting assembly is clamped on the inner wall of the first clamp 204, and the clamping column 305 is composed of two parts: a plastic cylinder and a plastic sphere. The forearm support skeleton 3 is fixedly connected to the end of the clamping column 305 away from the movable buckle 1. The forearm support skeleton 3 is composed of five "C"-shaped plastic plates and an arc-shaped plastic straight plate. From the overall perspective, the outline of the forearm support skeleton 3 is a semi-conical shape, in which the five "C"-shaped plastic plates are distributed in a linear array on the arc-shaped plastic straight plate, and the radius gradually decreases from one end of the arc-shaped plastic straight plate close to the clamping column 305 to the other end. Such a setting can not only facilitate the placement of the patient's forearm on the inner wall of the forearm support skeleton 3, but also can adapt to the outline of the patient's forearm.

[0051] The curved weakened grooves 304 are symmetrically provided on the inner wall of the "C"-shaped plastic plate close to the curved plastic straight plate. The five curved elastic plates 301 are respectively fixedly connected to the inner walls of the five "C"-shaped plastic plates on the forearm support frame 3. The curved elastic plates 301 are plastic plates with a curvature. When the patient inserts the forearm into the forearm support frame 3, the outward expansion curvature set on the forearm support frame 3 will be squeezed by the forearm, and the force drives the "C"-shaped plastic plate to expand outward and deform, which is convenient for the insertion of the forearm. After the patient completely inserts the forearm into the forearm support frame 3, the curved elastic plate 301 is deformed inward at both ends under the action of the patient's forearm's own gravity, and the "C"-shaped plastic plate is driven to bend inward in coordination with the weakened grooves 304. The second buckle 303 is fixedly connected to the end of the C-shaped elastic plate 302 away from the forearm support frame. The second buckle 303 is a "C"-shaped plastic plate with arcs expanding at both ends.

[0052] like Figures 2 to 15As shown, the limiting assembly includes two sliding columns which are respectively slidably connected to the sliding grooves opened in the two fixed plates 203, one end of the sliding column is fixedly connected to the airbag base 4, a snap-in groove 401 is opened on the inner wall of the airbag base 4, a rubber airbag 5 is snapped on the inner wall of the snap-in groove 401, and limiting arc plates 406 are respectively fixedly connected to the inner walls on both sides of the snap-in groove 401 near the top, one side of the limiting arc plate 406 is fixedly connected to the limiting snap-in plate 407, and semicircular limiting plates 408 are fixedly connected to the inner walls at both ends of the limiting arc plate 406, three arc connecting plates 402 are fixedly connected to the outer wall of one side of the airbag base 4, and one end of the three arc connecting plates 402 are all fixedly connected to the snap-in ring 403.

[0053] Specifically, the two sliding columns included in the limiting assembly are respectively slidably connected to the inner walls of the sliding grooves opened on the two fixed plates 203. The sliding column is composed of a plastic cylinder with a threaded groove at one end and a plastic circular plate. The plastic circular plate is arranged in the middle of the plastic cylinder. The airbag base 4 is fixedly connected to the end of the sliding column where the threaded groove is not arranged. The airbag base 4 is in the shape of a hollow semi-cylinder as a whole. A snap-in groove 401 is arranged on the side of the top outer wall of the airbag base 4 away from the second buckle 303. The connecting groove 401 is a square groove 9, and two limiting arc plates 406 are respectively fixedly connected to the inner walls on both sides of the clamping groove 401 near the top, and one side of the limiting arc plate 406 is fixedly connected with a limiting clamping plate 407 inclined toward the clamping groove 401, and the limiting clamping plate 407 is a "C"-shaped plastic plate with an arc, and the limiting clamping plate 407 is a plastic plate with an arc, and the semicircular limiting plate 408 is fixedly connected to the inner walls at both ends of the limiting arc plate 406, and the semicircular limiting plate 408 is a semicircular plastic plate.

[0054] A chamfer inclined toward the snap-fit ​​groove 401 is provided on the side of the top outer wall of the airbag base 4 close to the second snap buckle 303. The chamfer can facilitate the subsequent snap-fit. One end of the three arc-shaped connecting plates 402 are fixedly connected to the outer wall of the airbag base 4 close to the second snap buckle 303, and are distributed in an arc-shaped array. The arc-shaped connecting plates 402 are plastic plates with an arc. The other ends of the three arc-shaped connecting plates 402 are fixedly connected to the outer wall of the snap-fit ​​ring 403. The snap-fit ​​ring 403 is a plastic cylinder with an arc. 403 can be snapped onto the inner wall of the second snap buckle 303 mentioned above. Before use, the snap ring 403 can be aligned with the opening of the second snap buckle 303 and squeezed into the second snap buckle 303 along the outward expansion arc set on the second snap buckle 303. In this process, the second snap buckle 303 will deform along its bending direction until the snap ring 403 is completely squeezed into the second snap buckle 303. The second snap buckle 303 then restores its deformation and clamps the snap ring 403. This connection method is simple and quick.

[0055] A rubber airbag 5 is clamped on the inner wall of the clamping groove 401, three wrist contact surfaces 502 are arranged on the top outer wall of the rubber airbag 5, an air inlet pipe 501 is installed on the outer wall of the bottom of the rubber airbag 5 close to the airbag base 4, a first skeleton 6 is sleeved inside the rubber airbag 5, three first elastic plates 601 are fixedly connected to the outer wall of the first skeleton 6, one end of the first elastic plate 601 is fixedly connected to an arc-shaped support plate 603, and arc-shaped clamping plates 602 are fixedly connected to the outer walls on both sides of the arc-shaped support plate 603.

[0056] Specifically, the rubber airbag 5 is clamped on the inner wall of the clamping groove 401, and the three wrist contact surfaces 502 are all arranged on the top outer wall of the rubber airbag 5, distributed in an arc array, and the air inlet pipe 501 is installed on the outer wall of the bottom of the rubber airbag 5 close to the airbag base 4. The air inlet pipe 501 is a plastic hollow cylinder. The rubber airbag 5 is disclosed in the prior art, so it is not necessary to elaborate on it. After the rubber airbag 5 is inflated, the three wrist contact surfaces 502 will expand, and the patient's wrist can be lifted by the rubber airbag 5. The two sides and the middle of the patient's wrist can be resisted and limited, and the wrist part will not be strangled to cause discomfort to the patient. The first frame 6 is sleeved on the inner wall of the rubber airbag 5. The first frame 6 is a plastic plate with an arc. It is worth mentioning that the width of the first frame 6 is smaller than the limiting clamping plate 407 mentioned above. One end of the three first elastic plates 601 They are all fixedly connected to the middle position of the top outer wall of the first skeleton 6 and are distributed in an arc array. The first elastic plate 601 is an "S"-shaped plastic plate with an arc. When the first elastic plate 601 is subjected to a force in the direction of the first skeleton 6, the first elastic plate 601 will deform along the direction of its bending. The arc support plate 603 is fixedly connected to the end of the first elastic plate 601 away from the first skeleton 6. The arc support plate 603 is a plastic plate with an arc. Two arc clip plates 602 are symmetrically fixedly connected to the outer walls of both sides of the arc support plate 603 close to one end of the first elastic plate 601. The arc clip plates 602 are composed of three parts: a "C"-shaped plastic plate, a plastic straight plate and a plastic cylinder. The overall contour is "J"-shaped and has an arc, wherein the contour of the plastic cylinder part is adapted to the contour of the limiting arc plate 406 mentioned above.

[0057] Through the arrangement of the above structure, when the rubber airbag 5 is clamped to the clamping groove 401 of the airbag base 4, since the width of the first frame 6 is smaller than the above-mentioned limiting clamping plate 407, the first frame 6 can slide into the clamping groove 401 under the guidance of the limiting clamping plate 407. During the sliding process, the arc-shaped clamping plate 602 is subjected to the resistance force of the limiting clamping plate 407, and the part of the "C"-shaped plastic plate on the arc-shaped clamping plate 602 is forced toward the arc-shaped support plate. 603, the two parts of the plastic straight plate and the plastic cylinder on the arc-shaped clamping plate 602 will be displaced in the direction of the arc-shaped support plate 603. At this time, the pressing force in the direction of the clamping groove 401 can be continued until the first frame 6 contacts the bottom inner wall of the clamping groove 401 through the rubber airbag 5, and then press again to make the first elastic plate 601 deform in the direction of its bending. At this time, the arc-shaped clamping plate 602 completely slides into the clamping groove 4 01, and then the part of the "C"-shaped plastic plate on the arc-shaped clamping plate 602 will recover its deformation under the action of its own elasticity, driving the two parts of the plastic straight plate and the plastic cylinder on the arc-shaped clamping plate 602 to reset. At this time, no more pressure is applied, and the first elastic plate 601 will recover its deformation under the action of its own elasticity, and drive the arc-shaped clamping plate 602 to move toward the top of the airbag seat, so that the part of the arc-shaped clamping plate 602 with the plastic cylinder is against the inner wall of the limiting arc-shaped plate 406. When the rubber airbag 5 needs to be removed, it is only necessary to press the rubber airbag 5 in the direction of the airbag seat, so that the first elastic plate 601 is deformed along the bending direction under the force, and drive the arc-shaped clamping plate 602 to move in the direction of the pressing force until the arc-shaped clamping plate 602 is lower than the semicircular limiting plate 408, and then it can slide out in the direction of any end of the slot. The above structural setting can realize the installation and disassembly of the rubber airbag 5, thereby improving the work efficiency of medical staff.

[0058] One end of the arc-shaped support plate 603 is fixedly connected to the second frame 604, and two second elastic plates 605 are respectively fixedly connected to the two sides of the outer wall of the top of the second frame 604, and one end of the second elastic plate 605 is fixedly connected to the third frame 606, and an arc-shaped limit plate 609 is fixedly connected to the outer wall of one side of the third frame 606, and the arc-shaped limit plate 609 is provided with a first segmented groove, and a square groove 9 is provided in the middle of the third frame 606, and the inner walls of the two ends of the square groove 9 are respectively fixedly connected to the third elastic plates 607, and the two third elastic plates 607 One end of each of the two second elastic plates 605 is fixedly connected to the same arc-shaped support plate 608, and a second segmented groove is provided on the arc-shaped support plate 608. Specifically, the second skeleton 604 is fixedly connected to one end of the arc-shaped support plate 603 away from the first elastic plate 601. The second skeleton 604 is an arc-shaped plastic plate, and one end of the two second elastic plates 605 is symmetrically fixedly connected to both sides of the top outer wall of the second skeleton 604. The second elastic plate 605 is an "S"-shaped plastic plate, and the other ends of the two second elastic plates 605 are symmetrically fixedly connected to the outer walls on both sides of the third skeleton 606.

[0059] When the patient places his wrist on the rubber airbag 5, the third frame 606 will be compressed by the weight of the patient's wrist, causing it to move toward the airbag base 4. At this time, the second elastic plate 605 will be stressed and deformed in the direction of its bending. One end of the arc-shaped limiting plate 609 is fixedly connected to the outer wall of the third frame 606 on the side away from the forearm support frame 3. The other end of the arc-shaped limiting plate 609 is open, and the overall contour is an arc-shaped plastic plate expanding outward. Several segmented grooves are provided on the top outer wall of the end of the arc-shaped limiting plate 609 away from the third frame 606. Such a setting can adapt to the contour of the patient's wrist near the back of the hand. The square groove 9 is set in the middle position of the top outer wall of the third frame 606. The contour of the square groove 9 is a rectangular shape. One end of the two third elastic plates 607 is fixedly connected to the inner sides of the square groove 9. On the wall, the third elastic plate 607 is a "V"-shaped plastic plate, and the other ends of the two third elastic plates 607 are symmetrically fixedly connected to the outer walls at both ends of the arc-shaped support plate 608. The arc-shaped support plate 608 is a plastic plate with an arc, and a plurality of segmented grooves are provided on the outer wall of the arc-shaped support plate 608 on the side away from the arc-shaped limiting plate 609. Since the contour from the wrist to the forearm of a person is constantly expanding, when the patient places his wrist on the rubber airbag 5, the arc-shaped support plate 608 with the segmented grooves can adapt to the contour of the patient's wrist, and then under the action of the patient's wrist's own gravity, the arc-shaped support plate 608 will be pressed to move in the direction of the third skeleton 606, which will cause the third elastic plate 607 to be deformed along the direction of its bending. Such a structural setting can not only shape the rubber airbag 5, but also adapt to the contour of the patient's wrist, thereby improving the patient's comfort.

[0060] like Figures 6 to 13As shown, the other end of the sliding column is screwed with a fixing nut 404, and a clamping column 405 is fixedly connected to the outer wall of one end of the fixing nut 404, and a C-shaped support plate 7 is clamped on the outer wall of the sliding column. Specifically, the fixing nut 404 is screwed on the end of the sliding column with a threaded groove, and the fixing nut 404 consists of a plastic cylinder with an anti-slip groove on the outer wall and a plastic with a threaded ring. A clamping column 405 is fixedly connected to the outer wall of the fixing nut 404 on the side close to the airbag base 4, and the clamping column 405 is a plastic cylinder. Both ends of the C-shaped support plate 7 are respectively clamped on the outer wall of the end close to the fixing nut 404. The overall contour of the C-shaped support plate 7 is a "C"-shaped plastic plate, wherein "C"-shaped buckle structures are respectively provided at both ends of the C-shaped support plate 7, and two sliding clamping grooves 707 are respectively opened on the outer walls of the C-shaped support plate 7 close to both ends. When the C-shaped support plate 7 is clamped on the outer wall of the sliding column, it is necessary to first screw the fixing nut 404 until there is only a quarter turn left, and then align the "C"-shaped buckle structures set at both ends of the C-shaped clamping plate with the outer wall of the sliding column, and press the C-shaped support plate 7 in the direction of the sliding column. At this time, the "C"-shaped buckle structure set on the C-shaped support plate 7 will be stressed during the clamping process and deformed along the direction of its bending until it is clamped on the outer wall of the sliding column. Then, the "C"-shaped buckle structure set on the C-shaped support plate 7 will restore its deformation under the action of its own elasticity. At this time, tighten the fixing nut 404 for another quarter turn, and the clamping column 405 on the fixing nut 404 will slide to the inner wall of the sliding clamping groove 707. In this way, the C-shaped support plate 7 can be fixed in cooperation with the plastic circular plate part set on the sliding column to prevent loose clamping.

[0061] Two avoidance grooves 701 are provided on the C-shaped support plate 7, and a fixed cylinder 706 is fixedly connected to the inner wall of the avoidance groove 701, and a pinching rod 703 is rotatably connected to the outer wall of the fixed cylinder 706, and one end of the pinching rod 703 is fixedly connected to a limiting ring 704. Specifically, the two avoidance grooves 701 are symmetrically provided on both sides of the outer wall of the top of the C-shaped support plate 7, and the avoidance groove 701 is a quadrilateral groove body with an arc at both ends. The two ends of the fixed cylinder 706 are respectively fixedly connected to the inner walls of the two sides of the avoidance groove 701, and the fixed cylinder 706 is a plastic cylinder. The pinching rod 703 is rotatably connected to the fixed cylinder 706. On the outer wall of the fixed cylinder 706, the pinching rod 703 is an "S" shaped plastic plate, and the limiting ring 704 is fixedly connected to one end of the pinching rod 703. The limiting ring 704 is a hollow circular plastic plate, and two "C" shaped plastic plates are symmetrically arranged on the outer wall of the limiting ring 704. When the other end of the pinching rod 703 is pinched, the end fixedly connected to the limiting ring 704 will move toward the two ends of the C-shaped support plate 7, which will pull the limiting ring 704 to expand outward, so that the two "C" shaped plastic plates arranged on the outer wall of the limiting ring 704 are partially stressed and deformed along the direction of their bending.

[0062] A sliding hole 705 is provided in the middle of the C-shaped support plate 7, and a push column 801 is slidably connected to the inner wall of the sliding hole 705. One end of the push column 801 is fixedly connected to the push circular plate 8, and the other end of the push column 801 is fixedly connected to the rubber pad 803. Specifically, the sliding hole 705 is provided in the middle of the C-shaped support plate 7, and the sliding hole 705 is a circular groove body. The push column 801 is slidably connected to the inner wall of the sliding hole 705. The push column 801 is a plastic cylinder. Three limiting grooves 802 are provided on the outer wall of the end of the push column 801 close to the rubber airbag 5. The limiting grooves 802 are trapezoidal groove bodies and are distributed in a linear array, wherein the inclined surface is provided on the inner side of the limit position close to the top of the limiting ring 704. On the wall, such an arrangement facilitates the displacement of the propulsion column 801 on the inner wall of the limit ring 704 toward the rubber airbag 5. The propulsion circular plate 8 is fixedly connected to the outer wall of the end of the propulsion column 801 away from the rubber airbag 5. The propulsion circular plate 8 is a circular plastic circular plate. The two fourth elastic plates 702 are symmetrical about the propulsion column 801, and one end of the fourth elastic plate 702 is fixedly connected to the outer wall of the propulsion circular plate 8 on the side close to the propulsion column 801, and the other end of the fourth elastic plate 702 is fixedly connected to the top outer wall of the C-shaped support plate 7. The rubber pad 803 is fixedly connected to the other end of the propulsion column 801. The rubber pad 803 is used to apply pressure to the wound to stop bleeding, which is disclosed in the prior art, so it will not be repeated.

[0063] When in use, the pushing circular plate 8 is pressed, and the fourth elastic plate 702 is deformed in the direction of its bending due to the pressing force. At the same time, the pushing circular plate 8 will push the pushing column 801 to move in the direction of the rubber airbag 5. At this time, the limiting ring 704 will be forced to expand outward during the sliding contact of the inclined surface of the limiting groove 802, forcing the two "C"-shaped plastic plate parts set on the limiting ring 704 to be stressed and deformed in the direction of its bending. Only when the limiting ring 704 slides to the limiting groove 802 close to the pushing circular plate 8 can it restore its deformation under the action of its own elasticity, and at the same time it will resist the inner wall of the limiting groove 802 close to the rubber pad 803, and give the fourth elastic plate 702 a resistance to prevent it from restoring its deformation. When pressure release is required, it is only necessary to pinch the outer wall of the end of the pinching rod 703 away from the limiting ring 704. At this time, the end fixedly connected to the limiting ring 704 will move toward The displacement of the two ends of the C-shaped support plate 7 will pull the limit ring 704 to expand outward, so that the two "C"-shaped plastic plate parts set on the outer wall of the limit ring 704 are subjected to force and deformed along the direction of its bending. The fourth elastic plate 702 will recover its deformation under the action of its own elasticity without the resistance, and will push the propulsion circular plate 8 to move away from the C-shaped support plate 7, and then drive the propulsion rod to move away from the rubber airbag 5. Until the pinching rod 703 is released, the two "C"-shaped plastic plate parts set on the outer wall of the limit ring 704 will recover their deformation under the action of their own elasticity and slide to the next limit groove 802 to limit the propulsion column 801 again. Repeat the above operation to release the pressure again. The above structure is not only convenient to install, but also simple to operate. It can quickly realize rapid pressure relief of the patient's wound, thereby improving the work efficiency of medical staff.

[0064] The working principle of the technical solution provided by the present invention is as follows:

[0065] When in use, after the patient completely places the forearm into the forearm support frame 3, the arc-shaped elastic plate 301 is deformed to bend inward at both ends under the action of the patient's forearm's own gravity, and cooperates with the weakened groove 304 to drive the "C"-shaped plastic plate to bend inward to achieve clamping of the patient's forearm. At the same time, the patient's wrist will also be placed on the outer wall of the rubber airbag 5. Since the outline from the wrist to the forearm of a person is constantly expanding, when the patient places his wrist on the rubber airbag 5, the arc-shaped support plate 608 with segmented grooves can adapt to the patient. The contour of the wrist will then be compressed by the patient's wrist's own gravity to displace the arc-shaped support plate 608 toward the third skeleton 606, causing the third elastic plate 607 to be deformed along its bending direction. As the patient's wrist's own gravity acts, the third skeleton 606 will be compressed to displace toward the airbag base 4. At this time, the second elastic plate 605 will be stressed and deformed along its bending direction. The arc-shaped limiting plate 609 with segmented grooves will be forced to expand outward, which can adapt to the contour of the patient's wrist near the back of the hand.

[0066] At this time, after the C-shaped support plate 7 is installed on the airbag base 4, the push circular plate 8 is pressed, and the fourth elastic plate 702 is deformed in the direction of its bending due to the pressing force. At the same time, the push circular plate 8 will push the push column 801 to move in the direction of the rubber airbag 5. At this time, the limiting ring 704 will be forced to expand outward during the sliding contact of the inclined surface of the limiting groove 802, forcing the two "C"-shaped plastic plate parts set on the limiting ring 704 to be stressed and deformed in the direction of its bending until the limiting ring 704 slides to the limiting groove 802 close to the push circular plate 8, and then it can restore the deformation under the action of its own elasticity, and at the same time it will contact the limiting groove 802. On the inner wall of the side close to the rubber pad 803, a resistance force is given to the fourth elastic plate 702 to prevent it from restoring its deformation. At this time, the rubber pad 803 will be located close to the rubber airbag 5 as the propulsion column 801 slides, and then the rubber airbag 5 can be inflated. The rubber airbag 5 will expand and lift the patient's arm during the inflation process, and the three wrist contact surfaces 502 set on the rubber airbag 5 will also expand and bulge during the inflation process, while lifting the patient's wrist, it is limited and fixed until the wound on the patient's wrist is against the rubber pad 803, and then according to the doctor's experience, the inflation is stopped and the air inlet pipe 501 is closed. At this time, the patient's wound is pressurized to stop bleeding.

[0067] When pressure needs to be released during pressurized hemostasis, it is only necessary to pinch the outer wall of the end of the pinching rod 703 away from the limiting ring 704. At this time, the end fixedly connected to the limiting ring 704 will move toward the two ends of the C-shaped support plate 7, pulling the limiting ring 704 to expand outward, so that the two "C"-shaped plastic plate parts set on the outer wall of the limiting ring 704 are stressed and deformed along the direction of their bending. The fourth elastic plate 702 will restore its deformation under the action of its own elasticity without the resistance, and will push the propulsion circular plate 8 to move away from the C-shaped support plate 7, and then drive the propulsion rod to move away from the rubber airbag 5. Until the pinching rod 703 is released, the two "C"-shaped plastic plate parts set on the outer wall of the limiting ring 704 will restore their deformation under the action of their own elasticity and slide to the next limiting groove 802 to limit the propulsion column 801 again. Repeat the above operation to release the pressure again.
