Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pressure hemostasis device for cardiology nursing. Background Technology

[0002] Cardiology, or cardiovascular medicine, is a field where bleeding may occur during catheter intervention in arteries or catheter removal after treatment. In such cases, a pressure hemostatic device is used to apply pressure to the arterial site of the punctured catheter or its tip for an extended period to stop the bleeding, thereby reducing the workload of medical staff and conserving their energy.

[0003] When applying pressure to the bleeding site of a patient using a pressure hemostasis device, the pressure block on the device moves up and down to apply pressure to the bleeding site. However, since the pressure block can only move up and down, it is difficult for the pressure block to directly apply pressure to the bleeding site when the bleeding site is on the oblique side of the body, thus failing to fully exert its hemostatic function and achieve the desired hemostatic effect. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure hemostasis device for cardiology nursing, so as to solve the problem of difficulty in applying pressure to the oblique side of the body for hemostasis as mentioned in the background art.

[0013] Preferably, the bottom surface of the rotating bar is fixedly connected to the top surface of the circular plate, the bottom surface of the circular plate is fixedly connected to the top surface of the circular block through a fixing column, and a circular groove is provided on the top surface of the pressing block, with the inner wall of the circular groove slidingly connected to the outer wall of the pressing block.

[0014] Preferably, the outer wall of the circular block has three moving grooves, and three locking blocks are provided. The outer walls of the three locking blocks are slidably connected to the inner walls of the three moving grooves, and the inner walls of the circular grooves have three locking slots.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention adjusts the butterfly nut and bolt rod, then pushes the bolt rod to rotate the connecting block and the fixing sleeve by a certain angle. The fixing sleeve rotates the rotating bar by a certain angle, and the rotating bar rotates the pressing block below by a certain angle, so that the pressing block matches the oblique side of the patient. The pressing block applies pressure to the bleeding site on the oblique side of the patient to stop the bleeding. The pressing block can fully exert its hemostatic function, thereby improving the effect of pressure hemostasis.

[0021] By pushing the pressing block, the circular groove connects with the circular block. After the circular groove squeezes the locking block, under the action of the elastic element one, the locking block is pushed back to its original position and engages with the slot, thus fixing the pressing block. When disassembling, pushing the push plate causes the fixing strip to rotate at a certain angle, which in turn causes the disc to rotate at a certain angle. The arc groove two on the disc cooperates with the sliding groove to move the cylinder and the locking block. The locking block moves out of the slot and moves to the inner wall of the moving groove, making it easy and quick to disassemble the pressing block. When stopping bleeding on the patient's leg or arm, pressing blocks of different shapes can be easily and quickly replaced to adapt to different parts of the patient's body, so that the pressing block can fit the bleeding site of the patient more closely and improve the effect of pressure hemostasis.

[0022] With the set locking pins and locking holes, when the locking block and the locking slot are engaged to fix the pressing block, the locking pins and locking holes are engaged to fix the push plate, ensuring that the push plate is not easy to move, further ensuring that the pressing block is not easy to fall off, and further improving the stability of pressure hemostasis.

[0047] The fixing mechanism 3 is located on one side of the support frame 104. The fixing mechanism 3 includes a circular plate 301 and a circular block 303 located below the rotating bar 202. A locking block 306 is provided inside the circular block 303. A push plate 316 is provided above the circular plate 301. The fixing mechanism 3 is used to fix the pressing block 107.

[0048] Specifically, such as Figures 1-9As shown, the bottom surface of the rotating bar 202 is fixedly connected to the top surface of the circular plate 301. The bottom surface of the circular plate 301 is fixedly connected to the top surface of the circular block 303 through the fixing column 302. The top surface of the pressing block 107 has a circular groove 308, and the inner wall of the circular groove 308 is slidably connected to the outer wall of the pressing block 107.

[0049] In this embodiment, the bleeding site of the patient is stopped by applying pressure to the set pressure block 107.

The inner wall of the circular groove 308 has three locking slots 309, and the three locking blocks 306 are respectively engaged with the three locking slots 309.

[0051] In this embodiment: the movable groove 304 limits the position of the card block 306, and the card block 306 engages with the card groove 309, thereby fixing the pressing block 107.

[0052] Specifically, such as Figures 1-9 As shown, the upper inner walls of the three movable slots 304 are respectively provided with sliding grooves 305, and the top surfaces of the three locking blocks 306 are respectively fixedly installed with cylinders 307. The outer walls of the three cylinders 307 are respectively slidably connected to the inner walls of the three sliding grooves 305. The outer wall of the fixed column 302 is rotatably installed with a disc 310 through a bearing seat. The top surface of the disc 310 is provided with three arc-shaped grooves 311, and the inner walls of the three arc-shaped grooves 311 are respectively slidably connected to the outer walls of the three cylinders 307.

[0053] In this embodiment: through the arc-shaped groove 311, when the disk 310 rotates, the arc-shaped groove 311 cooperates with the sliding groove 305 to drive the cylinder 307 and the locking block 306 to move.

[0054] Specifically, such as Figures 1-9 As shown, three fixing strips 312 are fixedly installed on the top surface of the disc 310, and an arc-shaped groove 313 is opened through the top surface of the circular plate 301. The outer walls of the three fixing strips 312 are slidably connected to the inner walls of the three arc-shaped grooves 313 respectively. Arc-shaped rods 314 are slidably installed through the sides of the three fixing strips 312 respectively, and the two ends of the three arc-shaped rods 314 are fixedly connected to the inner walls of the three arc-shaped grooves 313 respectively.

[0055] In this embodiment, the fixed bar 312 is limited by the arc-shaped rod 314, so that the fixed bar 312 moves more stably.

[0056] Specifically, such as Figures 1-9As shown, elastic elements 315 are slidably installed on the outer walls of the three arc-shaped rods 314 respectively. The two ends of the three elastic elements 315 are fixedly connected to the side of the fixing strip 312 and the inner wall of one side of the arc-shaped groove 313 respectively. The upper side of one side of the fixing strip 312 is fixedly connected to the side of the push plate 316.

[0057] In this embodiment, the elastic element 315 is used to apply elastic force to the fixing strip 312.

[0058] Locking mechanism 4 is located on one side of support frame 104. Locking mechanism 4 includes a locking post 401 located above circular plate 301. A locking hole 405 is opened on the top surface of circular plate 301. Locking mechanism 4 is used to lock push plate 316.

[0059] Specifically, such as Figures 1-9 As shown, the upper end of the locking post 401 slides through the bottom surface of the push plate 316 and extends above the push plate 316. A pull plate 404 is fixedly installed on the top surface of the locking post 401. The lower end of the locking post 401 is engaged with the locking hole 405. A round sleeve 402 is fixedly installed on the outer wall of the locking post 401. An elastic element 403 is slidably installed on the outer wall of the locking post 401. The two ends of the elastic element 403 are fixedly connected to the bottom surface of the push plate 316 and the top surface of the round sleeve 402, respectively.

[0060] In this embodiment: the push plate 316 is locked when the locking post 401 and the locking hole 405 are engaged.

[0061] Specifically, the mounting bracket 1 is fitted onto the bed frame. Rotating the screw 103 moves the fixing block 106 to secure the device. Pushing the pressing block 107 connects the circular groove 308 with the circular block 303. After the circular groove 308 presses against the locking block 306, the elastic element 315 pushes the locking block 306 back to its original position and engages with the locking groove 309, thus securing the pressing block 107. During disassembly, pushing the push plate 316 rotates the fixing strip 312 by a certain angle, which in turn rotates the disc 310 by a certain angle. The arc-shaped groove 311 and the sliding groove 305 on the disc 310 cooperate to drive the cylinder 307 and the locking block 306 to move. The locking block 306 moves out of the locking groove 309 and moves to the inner wall of the moving groove 304, which facilitates the quick and easy disassembly of the pressure block 107. When stopping bleeding on the patient's leg or arm, different shaped pressure blocks 107 can be easily and quickly replaced to adapt to different parts of the patient's body, so that the pressure block 107 can fit the bleeding site more closely and improve the effect of pressure hemostasis. The locking post 40 is set. 1. When the locking block 306 engages with the locking slot 309 to fix the pressing block 107, the locking post 401 engages with the locking hole 405, thereby fixing the push plate 316 and ensuring that the push plate 316 is not easy to move, further ensuring that the pressing block 107 is not easy to fall off, and further improving the stability of hemostasis by pressing. Adjust the butterfly nut 210 and the bolt rod 207, and then push the bolt rod 207 to drive the connecting block 206 and the fixing sleeve 203 to rotate a certain angle. The fixing sleeve 203 drives the rotation. The movable bar 202 rotates at a certain angle, causing the lower pressing block 107 to rotate at a certain angle, so that the pressing block 107 matches the oblique side of the patient. The pressing block 107 applies pressure to the bleeding site on the oblique side of the patient to stop the bleeding. The pressing block 107 can fully exert its hemostatic function, thereby improving the effect of pressure hemostasis. Adjusting the support frame 104 adjusts the height and horizontal distance of the pressing block 107, so that the pressing block 107 applies pressure to the bleeding site of the patient to stop the bleeding.
