[0002] In today's society, coronary heart disease has become the number one killer of humans. Percutaneous transluminal coronary angioplasty (PTCA) has become one of the main means of treating coronary heart disease. There are two puncture routes: femoral artery and radial artery. Femoral artery puncture has many inconveniences and disadvantages, while radial artery puncture is more effective. The number of patients undergoing radial artery puncture has increased dramatically every year.

[0003] A radial artery compression device after coronary intervention disclosed in a patent application with reference publication number CN216797741U belongs to the technical field of medical equipment. The radial artery compression device after coronary intervention comprises a fixing frame, the lower end of which is fixedly connected to a supporting frame, the outer end of the fixing frame is penetrated by a fixing block fixedly connected thereto, and the lower end of the fixing block extends into the inside of the fixing frame, the upper end of the fixing block is provided with a threaded through hole, a threaded rod is rotatably connected in the threaded through hole, and the lower end of the threaded rod extends into the inside of the fixing frame, a compression plate is arranged inside the fixing frame, and two sliding rods distributed on the left and right are fixedly connected to the upper end of the compression plate, the upper end of the sliding rod penetrates the fixing frame and extends to the upper side of the fixing frame, which can facilitate medical staff to compress and stop bleeding on the patient, and can effectively avoid the patient moving his arm during the compression process, resulting in failure of hemostasis, thereby effectively reducing the workload of medical staff and the pain of patients.

[0004] After the actual coronary intervention, the radial artery is punctured and the needle is pulled out from the puncture site. At this time, the medical staff presses the puncture point with a cotton swab. After pressing for a certain period of time, the puncture site needs to be compressed for up to 6 hours. The existing method is to wrap the wrist with a bandage for compression, but the puncture site is often only a point. Long-term compression of the artery and vein will cause discomfort to the personnel, and the puncture point cannot be accurately compressed. In addition, during the compression process, the bandage will bleed. In order to ensure that the puncture site will not be infected, the gauze needs to be replaced. At this time, the compression needs to be released, which is too cumbersome.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 10 As shown, a radial artery compression device after coronary intervention and a method of using the same include the following embodiments:

[0043] like Figures 1 to 5 As shown, embodiment 1 includes a support frame 1, both sides of the support frame 1 are fixedly connected to side frames 101, and one side of the two side frames 101 is fixedly connected to Velcro 103 for adhesion, and also includes:

[0044] A rotating ring 2 is fixedly connected to the top of the support frame 1, and support columns 100 are fixedly connected to the bottom of the support frame 1. Suction cups 104 are fixedly connected to the bottoms of the four support columns 100. A clamping piece is arranged inside the rotating ring 2, and a first bevel gear disc 206 is rotatably connected to the outer side of the rotating ring 2, which is used to drive the clamping piece to position the support frame 1;

[0045] The bottom of the rotating ring 2 is fixedly connected with an external threaded barrel 3, the bottom of the external threaded barrel 3 is provided with a fixed ring 4, a compression frame 5 is provided inside the fixed ring 4, a compression piece for squeezing the puncture point is provided inside the compression frame 5, and a connecting piece for moving the compression piece to the center of the fixed ring 4 is provided between the compression frame 5 and the fixed ring 4;

[0046] An internal thread ring 401 is fixedly connected to the top of the fixing ring 4 , and the internal thread ring 401 is threadedly connected to the outside of the external thread tube 3 . A flexible ring 403 is fixedly connected to the bottom of the fixing ring 4 .

[0047] In specific implementation, after the radial artery is completed after the actual coronary intervention, the needle is pulled out from the puncture site. At this time, the medical staff presses the puncture point with a cotton swab. After pressing for a certain period of time, the puncture site needs to be compressed for up to 6 hours. The existing bandage is used to wrap and compress the wrist, but the puncture site is often only a point. Long-term compression of the artery and vein will cause discomfort to the personnel, and the puncture point cannot be accurately compressed. Therefore, in this solution, the support frame 1 is passed through the cotton swab so that the suction cups 104 around the bottom of the support frame 1 are in contact with the skin on the wrist; then, by rotating the first bevel gear plate 206, the clamping piece clamps the cotton swab in the center, adjusts the position of the support frame 1 so that the puncture is at the center of the rotating ring 2, pre-positions the support frame 1, and then adheres the support frame 1 to the wrist through two Velcro strips 103, thereby pre-positioning the support frame 1, and then pulls the cotton swab out of the clamping piece, and then pushes the connecting piece to move the compression frame 5 to the top of the puncture, and finally rotates the internal threaded ring 401 to lower the fixing ring 4, thereby driving the compression piece on the compression frame 5 to compress the puncture site, avoiding the need to repeatedly adjust the position after the needle is removed, and ensuring accurate compression of the puncture point.

[0048] like Figures 2 to 3 As shown, in this embodiment, the clamping member includes a plurality of clamping plates 204 arranged in a ring around the center of the rotating ring 2, a plurality of contact wheels 205 are rotatably connected to one side of the plurality of clamping plates 204, a plurality of threaded cylinders 203 are fixedly connected to the other side of the plurality of clamping plates 204, a plurality of first threaded rods 201 are internally threadedly connected to the plurality of threaded cylinders 203, a plurality of first threaded rods 201 all penetrate the rotating ring 2 and are rotatably connected to the rotating ring 2, a plurality of first threaded rods 201 are fixedly connected to one end of the plurality of first threaded rods 201, a plurality of first bevel gears 202 are meshedly connected to the first bevel gear disk 206, a first telescopic rod 207 is fixedly connected between the plurality of clamping plates 204 and the rotating ring 2, and a protective cover 200 for protecting the first bevel gear 202 is fixedly connected to the outer side of the rotating ring 2.

[0049] During specific implementation, when the cotton swab is inside the rotating ring 2, by rotating the first bevel gear disk 206, the first bevel gear disk 206 drives multiple meshing first bevel gears 202, and the first bevel gear 202 drives the fixedly connected first threaded rod 201 to rotate. The first threaded rod 201 is threadedly connected to the threaded cylinder 203, and the clamping plate 204 is fixedly connected to the threaded cylinder 203, and the first telescopic rod 207 is fixedly connected between the clamping plate 204 and the rotating ring 2. The clamping plate 204 is limited by the first telescopic rod 207, so that multiple clamping plates 204 move toward the cotton swab. Since the rod plate is in the hands of the medical staff at this time, the position of the support frame 1 is adjusted according to the cotton swab, so that the cotton swab is at the center of the rotating ring 2, so that the center position of the rotating ring 2 and the puncture point remain in the same straight line.

[0050] like Figures 5 and 6As shown, embodiment 2: the connecting member includes a fixed frame 601 fixedly connected to the bottom of the fixed ring 4, a rack 602 is slidably connected inside the fixed frame 601, one end of the rack 602 is fixedly connected to the compression frame 5, and a limiting rod 605 is fixedly connected to the bottom of one end of the rack 602, the limiting rod 605 penetrates the fixed frame 601 and is slidably connected to the fixed frame 601, a reset spring 606 is fixedly connected between the rack 602 and the fixed frame 601, and the reset spring 606 is sleeved on the outside of the limiting rod 605, for pulling the rack 602 away from the center of the fixed ring 4.

[0051] The connecting piece also includes a limit pawl 603 for limiting the reset of the rack 602. The limit pawl 603 is connected to the fixed frame 601 through a torsion spring. A traction rope 604 is fixedly connected to the outer side of the limit pawl 603 for pulling the limit pawl 603 to rotate. The limit pawl 603 passes through the fixed ring 4 and is slidably connected to the fixed ring 4.

[0052] In specific implementation, after the support frame 1 completes the pre-positioning, the cotton swab is pulled out of the rotating ring 2. At this time, the rack 602 is pushed, and the rack 602 moves to the limit position, so that the compression piece on the compression frame 5 fixedly connected to one end of the rack 602 is at the center position, so as to accurately find the puncture point, and the limit pawl 603 limits the rack 602 so that the limit pawl 603 will not move;

[0053] Then, by rotating the internal thread ring 401, the internal thread ring 401 drives the fixedly connected fixing ring 4 to descend, so that the flexible ring 403 contacts the skin, and the compression piece on the compression frame 5 compresses the puncture point.

[0054] like Figures 7 and 8 As shown, embodiment three: the compression member includes a support plate 502 fixedly connected to the inside of the compression frame 5, the support plate 502 has a second threaded rod 506 threadedly connected inside, one end of the second threaded rod 506 is rotatably connected to a compression head 505, the bottom of the compression head 505 is arc-shaped, and a limited telescopic rod is fixedly connected between the compression head 505 and the support plate 502.

[0055] Side plates 503 are provided on both sides of the support plate 502, and a winding rod 501 is provided on one side of the two side plates 503. The winding rod 501 passes through the side plates 503 and is rotatably connected to the side plates 503. A gauze roll 504 is fixedly sleeved on the outside of one of the winding rods 501, and the other end of the gauze roll 504 passes through the bottom of the pressing head 505 and is fixedly connected to the outside of the other winding rod 501. A servo motor is provided at one end of the other winding rod 501, and the output shaft of the servo motor is fixedly connected to the winding rod 501, and a fixed pulley is fixedly connected to the outside of the winding rod 501.

[0056] During specific implementation, the gauze roll 504 is squeezed by the compression head 505 to make the gauze roll 504 contact with the puncture point. During a long period of pressing, bleeding will occur at the puncture point. In order to ensure that the puncture point will not be infected, the gauze roll 504 needs to be replaced. Therefore, in this solution, the servo motor is started at a timer, and the servo motor drives one of the winding rods 501. The winding rod 501 winds the gauze roll 504, and the used part is rolled up, so that the clean part is pressed and contacted with the puncture site, thereby ensuring that the puncture site will not be infected when pressed for a long time.

[0057] In this solution, a detachable cover plate can be provided on one side of the compression frame 5, and the gauze roll 504 can be replaced later. The gauze roll 504 adopts a gauze reel, which is detachably mounted on one of the winding rods 501, and one end of the gauze on the reel is fixedly connected to the other reel.

[0058] like Fig. 9 As shown, in the present embodiment, a second bevel gear disc 508 is rotatably connected to the top of the support plate 502, and the second bevel gear disc 508 is sleeved on the outside of the second threaded rod 506, and a protrusion is fixed to the inner wall of the second bevel gear disc 508, and the protrusion extends to the inside of the sliding groove 507 opened on the outside of the second threaded rod 506, and is slidably connected to the second threaded rod 506, and a second bevel gear 509 is meshingly connected to the outside of the second bevel gear disc 508, and a rotating rod 511 is fixedly connected to one side of the second bevel gear 509, and a first pulley 510 is fixedly connected to the outside of the compression frame 5, and the first pulley 510 is connected to the fixed pulley by a belt transmission.

[0059] During specific implementation, as the compression time increases, the compression force needs to be continuously adjusted. When the servo motor drives one of the winding rods 501 to rotate, the winding rod 501 drives the rotating rod 511 to rotate through the fixed pulley and the first pulley 510 on the rotating rod 511 through belt transmission. The rotation of the rotating rod 511 drives the fixedly connected second bevel gear 509 to rotate, and the second bevel gear 509 drives the meshingly connected second bevel gear plate 508 to rotate. At this time, the second threaded rod 506 is driven to rotate through the protrusion. Since the second threaded rod 506 is threadedly connected to the support plate 502, the second threaded rod 506 rotates and rises, driving the compression head 505 fixedly connected at the bottom to move and rise, thereby automatically adjusting the compression force.

[0060] like Fig.10 As shown, in the fourth embodiment, the compression frame 5 is fixedly connected to the inside with an air cylinder 7, the outside of the air cylinder 7 is fixedly connected to an air supply pipe 702, one end of the air supply pipe 702 is provided with a nozzle, and the outside of the air supply pipe 702 is provided with an electric control valve.

[0061] A second pulley 801 is connected to the inside of the compression frame 5, and a third pulley 802 is fixedly connected to the outside of the rotating rod 511. A rotating disk 803 is fixedly connected to one side of the second pulley 801, and a plurality of pushing rods 804 are fixedly connected to the outside of the rotating disk 803. A trigger rod 805 is provided on one side of the second pulley 801, and a second telescopic rod 807 and a traction spring 808 are fixedly connected between one end of the trigger rod 805 and the compression frame 5. The traction spring 808 is sleeved on the outside of the second telescopic rod 807. A touch switch 806 is provided at the other end of the trigger rod 805 for controlling the opening of the electric control valve. The touch switch 806 is fixedly connected to the inner wall of the compression frame 5.

[0062] During specific implementation, when the rotating rod 511 rotates through the belt transmission between the third pulley 802 and the second pulley 801, the second pulley 801 drives the fixedly connected rotating disk 803 to rotate, and the rotating disk 803 drives the push rod 804 fixedly connected on the outside to rotate, and then the push rod 804 is continuously in contact with the trigger rod 805, pushing the trigger rod 805 to move upward, so that one end of the trigger rod 805 presses the touch switch 806, and the touch switch 806 controls the electric control valve on the outside of the air supply pipe 702 to make the gas inside the air cylinder 7 spray to the pressing part through the nozzle of the air supply pipe 702. Since the trigger rod 805 is fixedly connected to the inner wall of the compression frame 5 by the traction spring 808 and the second telescopic rod 807, it automatically and quickly resets after each push. Therefore, when the trigger rod 805 triggers the touch switch 806 each time, the nozzle sprays intermittently, thereby improving air flow and cooling and soothing the pressing part.

[0063] A control valve is provided on the top of the gas cylinder 7, and personnel can inject compressed gas into it for replenishment later.

[0064] A method for radial artery compression after coronary intervention is also provided, comprising the following steps:

[0065] Step 1: After the operation is completed, the needle is pulled out from the puncture site. At this time, the medical staff presses the puncture point with a cotton swab. When the staff presses the cotton swab, the support frame 1 passes through the cotton swab so that the suction cups 104 around the bottom of the support frame 1 contact the skin on the wrist;

[0066] Step 2: Rotate the first bevel gear plate 206 to make the clamping member clamp the cotton swab in the center, adjust the position of the support frame 1 so that the puncture is at the center of the rotating ring 2, pre-position the support frame 1, and then adhere the support frame 1 to the wrist through two Velcro strips 103;

[0067] Step 3: then pull the cotton swab out of the clamping piece, and then push the connecting piece to move the compression frame 5 to the top of the puncture;

[0068] Step 4: Finally, the fixing ring 4 is lowered by rotating the internal thread ring 401, thereby driving the compression member on the compression frame 5 to compress the puncture site.
