Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for removing bandages after femoral artery intervention. Background Technology

[0002] After interventional surgery, in order to achieve hemostasis at the femoral artery puncture site, an internal occluder is often used for initial closure. Although the internal occluder can achieve mechanical closure of the vascular puncture site to a certain extent, in order to prevent early postoperative activity or blood pressure fluctuations from causing occlusion failure or local bleeding, it is usually necessary to apply an elastic bandage to the puncture site for continuous pressure dressing for 24 hours.

[0003] In clinical practice, existing elastic bandages mostly use highly viscous adhesive to ensure secure fixation and maintain continuous pressure. However, when removing the elastic bandage after 24 hours, the strong adhesion between the adhesive and the patient's skin often causes significant pain, skin damage, and bleeding at the puncture site due to forceful peeling. To reduce these adverse reactions, medical staff usually need to apply adhesive remover evenly to the area where the elastic bandage adheres to the skin with a cotton swab while slowly peeling off the bandage. This method affects the work efficiency of medical staff. Therefore, this invention provides an auxiliary device for bandage removal after femoral artery intervention to meet this need. Summary of the Invention

[0004] This invention provides an auxiliary device for removing bandages after femoral artery intervention, which solves the technical problem of low work efficiency caused by the existing elastic bandage removal process, in which medical staff usually need to use a cotton swab to apply adhesive remover evenly to the adhesive area between the bandage and the skin, and then slowly tear off the elastic bandage by hand.

The infusion grooves are connected to the inner wall of the L-shaped tube. A C-shaped tube is fixedly connected to the end of the L-shaped tube away from the third rotating protrusion. A snap-fit ​​protrusion is fixedly connected to the end of the C-shaped tube away from the L-shaped tube.

[0010] Optionally, the injection cylinder is disposed on the inner wall of the first rotating groove near the second sliding groove, a second gear is rotatably connected to the inner wall of the first rotating groove, the second gear meshes with the first gear, and a fourth rotating protrusion is fixedly connected to the outer wall of the second gear near the fixed round seat.

[0011] Optionally, a plurality of fixed posts arranged in a circular array are fixedly connected to the outer wall of the second gear away from the fourth rotating protrusion, a limit plate is fixedly connected to the end of the fixed post away from the second gear, and a first elastic clamp is fixedly connected to the outer wall of the second gear near the fixed post.

[0015] Optionally, a rotating plate is rotatably connected to the outer wall of the second rotating protrusion, a connecting plate is fixedly connected to the outer wall of the rotating plate, a support plate is fixedly connected to the side wall of the connecting plate, and a C-shaped buckle is fixedly connected to the end of the connecting plate away from the rotating plate.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0021] By setting a rotating plate, connecting plate, support plate and C-shaped buckle in the auxiliary component, the C-shaped buckle can be engaged with the outer wall of the C-shaped tube during use. This can limit the connecting plate and prevent the second rotating protrusion from driving the rotating plate and connecting plate to rotate synchronously during rotation, thus affecting the support plate's ability to lift the elastic bandage after removal. It can also limit the buckling protrusion and prevent it from coming out of the inner wall of the buckling groove. Attached Figure Description

[0034] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 10 As shown, an embodiment of the present invention provides an auxiliary device for removing bandages after femoral artery intervention, including a handle 1. A motor is installed inside the handle 1. One end of the handle 1 is fixedly connected to a first gear 7 through the output shaft of the motor. A pulley 8 is fixedly connected to the outer wall of the first gear 7 on the side away from the handle 1. A button 3 is installed on the outer wall of the handle 1 near the middle. Several grip grooves 2 are formed in a linear array on the outer wall of the handle 1 near the button 3.

[0036] Specifically, the handle 1 is a cylinder made of plastic, and a motor is installed inside it. The output shaft of the motor extends from one end of the handle 1. The first gear 7 is fixedly connected to the output end of the motor, and the first gear 7 is made of metal. The pulley 8 is fixedly connected to the outer wall of the first gear 7 away from the handle 1. The pulley 8 is a cylinder with an I-shaped cross-section. When the motor in the handle 1 drives the output shaft to rotate, the first gear 7 and the pulley 8 will rotate synchronously with the output shaft. The button 3 is installed on the outer wall of the handle 1 near the middle. The button 3 is the motor switch, used to start or stop the motor. The structure and operating principle of the button 3 and the motor are disclosed as prior art and will not be described in detail here. Several grip grooves 2 are opened on the outer wall of the handle 1 near the button 3, and the grip grooves 2 are arranged in a linear array. The grip grooves 2 are arc-shaped grooves. The grip grooves 2 are designed to facilitate medical personnel to hold the handle 1.

[0037] The auxiliary components include an injection cylinder 11, an L-shaped tube 18, and a roller 14. The injection cylinder 11 contains the adhesive remover, the L-shaped tube 18 is connected to the injection cylinder 11 and is used to deliver the adhesive remover, and the roller 14 is positioned corresponding to the outlet of the L-shaped tube 18. Through the coordinated operation of these three core functional components—the injection cylinder 11, the L-shaped tube 18, and the roller 14—the storage, directional delivery, and mechanical application of the adhesive remover are integrated. The adhesive remover, pre-stored in the injection cylinder 11, is pressed into the L-shaped tube 18 during operation and delivered to the outlet position. The roller 14 is positioned at the corresponding outlet, allowing the adhesive remover to be continuously applied to its working surface. When the roller 14 is placed between the patient's skin and the elastic bandage and moves, it simultaneously and evenly applies the adhesive remover to the adhesive interface while gradually separating the two, thereby instantly dissolving the sticky adhesive during the separation process.

[0038] The auxiliary component helps medical staff remove elastic bandages from patients. By setting up the auxiliary component, it can not only assist in tearing off the elastic bandages from the patient's skin during the application of adhesive remover, reducing the patient's pain and improving the work efficiency of medical staff, but also automatically replenish adhesive remover during the removal process, avoiding contamination of unused adhesive remover. In addition, it can automatically roll up the torn elastic bandages for easy collection and disposal by medical staff.

[0039] This device integrates the storage, delivery, and application of adhesive remover into a single-handed controllable unit, enabling simultaneous application and separation operations. This significantly simplifies the procedure and improves medical efficiency. The combination of directional delivery and roller application allows for precise and continuous application of the solution at the separation front, effectively reducing skin pain and damage caused by adhesive adhesion and improving patient comfort. Smooth mechanical separation combined with immediate adhesive removal helps maintain puncture site stability and reduces the risk of secondary bleeding.

[0040] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the auxiliary component also includes a fixing plate 6, which is fixedly connected to the outer wall of the handle 1 near the first gear 7. A second rotating groove 12 is provided on the outer wall of the fixing plate 6 away from the handle 1. A roller 14 is rotatably connected to the inner wall of the second rotating groove 12. A first rotating protrusion 16 is fixedly connected to the end wall of the roller 14 near the fixing plate 6. A linkage groove 15 is provided on the outer wall of the roller 14 near the first rotating protrusion 16. A belt 38 is tensioned between the roller 14 and the pulley 8.

[0041] Specifically, one end of the fixed plate 6 is fixedly connected to the outer wall of the handle 1 near the first gear 7, and the other end is open. The second rotating groove 12 is formed on the outer wall of the fixed plate 6 away from the handle 1. The second rotating groove 12 is a circular groove, and a roller 14 is rotatably connected to the inner wall of the second rotating groove 12. The roller 14 is a metal cylinder. A first rotating protrusion 16 is fixedly connected to the end of the roller 14 near the fixed plate 6. The first rotating protrusion 16 is a convex metal cylinder. Since the outer contour of the first rotating protrusion 16 matches the inner contour of the second rotating groove 12, the first rotating protrusion 16 can rotate on the inner wall of the second rotating groove 12. The linkage groove 15 is formed on the roller 14 near the first gear 7. On the outer wall of the rotating protrusion 16, the linkage groove 15 is a square-shaped annular groove. Since the inner wall contour of the linkage groove 15 matches the inner wall contour of the pulley 8, a belt 38 can be tensioned between the linkage groove 15 and the pulley 8. When the pulley 8 rotates, the roller 14 can be driven by the belt 38 to rotate synchronously with the pulley 8. Since the inner circumferential diameter of the linkage groove 15 is smaller than the inner circumferential diameter of the groove on the pulley 8, the rotation speed of the roller 14 will be greater than the speed of the pulley 8. When the roller 14 is placed between the patient's skin and the elastic bandage, the rotation of the roller 14 can separate the elastic bandage from the patient's skin, which effectively reduces the patient's pain compared to the traditional tearing method.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a third rotating groove 13 is provided on the outer wall of the fixed plate 6 near the second rotating groove 12. An L-shaped tube 18 is rotatably connected to the inner wall of the third rotating groove 13. A third rotating protrusion 19 is fixedly connected to one end of the L-shaped tube 18 near the fixed plate 6. A shovel plate 20 is fixedly connected to the outer wall of the L-shaped tube 18. Several infusion grooves 21 are provided on the outer wall of the shovel plate 20 in a linear array. The infusion grooves 21 are connected to the inner wall of the L-shaped tube 18. A C-shaped tube 22 is fixedly connected to one end of the L-shaped tube 18 away from the third rotating protrusion 19. A snap-fit ​​protrusion 23 is fixedly connected to one end of the C-shaped tube 22 away from the L-shaped tube 18.

[0043] Specifically, the third rotating groove 13 is formed on the outer wall of the fixed plate 6 near the second rotating groove 12. The third rotating groove 13 is a circular groove. One end of the L-shaped tube 18 is rotatably connected to the inner wall of the third rotating groove 13. The L-shaped tube 18 is an L-shaped hollow plastic tube. The third rotating protrusion 19 is fixedly connected to the end of the L-shaped tube 18 near the fixed plate 6. The third rotating protrusion 19 is a plastic cylinder with an I-shaped cross-section. The outer contour of the third rotating protrusion 19 matches the inner contour of the third rotating groove 13. Therefore, the third rotating protrusion 19 can rotate on the inner wall of the third rotating groove 13. Rotating, the C-shaped tube 22 is fixedly connected to the end of the L-shaped tube 18 away from the L-shaped tube 18. The C-shaped tube 22 is a hollow plastic tube with a C-shaped structure. When the C-shaped tube 22 is subjected to force, it will deform along its bending direction. The snap-fit ​​protrusion 23 is fixedly connected to the end of the C-shaped tube 22 away from the L-shaped tube 18. The snap-fit ​​protrusion 23 is a hollow protrusion made of rubber, and its overall outline is I-shaped. The end of the snap-fit ​​protrusion 23 away from the C-shaped tube 22 is provided with an arc. The adhesive remover can enter the C-shaped tube 22 through the inner wall of the snap-fit ​​protrusion 23, and then enter the L-shaped tube 18 through the inner wall of the C-shaped tube 22. Inside the tube 18, one end of the shovel plate 20 is fixedly connected to the outer wall of the L-shaped tube 18. The shovel plate 20 is an arc-shaped plastic plate, and the other end of the shovel plate 20 is an open end that can abut against the outer wall of the roller 14. When the C-shaped tube 22 rotates, it will drive the L-shaped tube 18 to rotate. At this time, the third rotating protrusion 19 will rotate along the inner wall of the third rotating groove 13 under the drive of the L-shaped tube 18. At the same time, the shovel plate 20 will rotate with the L-shaped tube 18 until the open end of the shovel plate 20 abuts against the outer wall of the roller 14. At this time, the shovel plate 20 will be subjected to force and deform along its bending direction. The elasticity of the spatula 20 causes its open end to fit tightly against the outer wall of the roller 14. As the roller 14 rotates, the spatula 20 can remove the adhesive adhering to the outer wall of the roller 14. Several infusion tanks 21 arranged in a linear array are opened on the outer wall of the spatula 20. The infusion tank 21 is a semi-circular tank, one end of which is connected to the inner wall of the L-shaped tube 18, and the other end of which passes through the open end of the spatula 20. The infusion tank 21 can guide the adhesive remover in the L-shaped tube 18 to the outer wall of the roller 14. As the roller 14 rotates, it is evenly applied to the adhesion between the elastic bandage and the patient's skin.

[0044] When medical staff use this device, they place the outer wall of roller 14 between the patient's skin and the elastic bandage, and then press button 3 with their index finger to start the motor inside the handle 1. The motor drives the output shaft to rotate, which in turn drives the first gear 7 and pulley 8 to rotate synchronously. Driven by belt 38, roller 14 rotates together with pulley 8. As roller 14 rotates, the elastic bandage can be gradually separated from the patient's skin. As roller 14 rotates, the adhesive dissolved by the adhesive remover may adhere to the outer wall of roller 14. At this time, the scraper plate 20, which abuts against the outer wall of roller 14, can scrape off the adhered adhesive in time to prevent it from affecting the subsequent application of adhesive remover. The above structure can automatically apply adhesive remover during the separation of elastic bandage from patient's skin, dissolving the adhesive on the elastic bandage, thereby effectively reducing the pain of the patient when tearing off the elastic bandage.

[0045] like Figures 1 to 5 , Figure 7 and Figure 8 As shown, the auxiliary component also includes a fixed circular seat 5, which is fixedly connected to the outer wall of the handle 1 near the first gear 7. A first rotating groove 9 is formed on the end wall of the fixed circular seat 5 away from the middle of the handle 1, and a second sliding groove 10 is formed on the end wall of the fixed circular seat 5 near the middle of the handle 1. The second sliding groove 10 is connected to the first rotating groove 9. The injection cylinder 11 is disposed on the inner wall of the first rotating groove 9 near the second sliding groove 10. A cover plate 29 is fitted on the outer wall of the end of the injection cylinder 11 away from the second gear 24. The cover plate 29 is close to the injection cylinder. A cover groove 32 is provided on the end wall of the cylinder 11. A snap-fit ​​groove 33 is provided on the end wall of the cover plate 29 away from the cover groove 32. The snap-fit ​​groove 33 is connected to the cover groove 32. A first sliding groove 4 is provided on the outer wall of the handle 1 near the fixed round seat 5. A sliding plate 41 is slidably connected to the inner wall of the first sliding groove 4. A push rod 40 is fixedly connected to the outer wall of the sliding plate 41 near the first gear 7. A piston 39 is fixedly connected to the end of the push rod 40 away from the sliding plate 41. A push plate 42 is fixedly connected to the outer wall of the sliding plate 41 away from the push rod 40.

[0046] Specifically, the fixed cylindrical base 5 is fixedly connected to the outer wall of the handle 1 near the first gear 7. The fixed cylindrical base 5 is a plastic cylinder, and a first rotating groove 9 is formed on the end wall of the fixed cylindrical base 5 away from the middle of the handle 1. The first rotating groove 9 is a convex groove. A second sliding groove 10 is formed on the outer wall of the fixed cylindrical base 5 near the middle of the handle 1. The second sliding groove 10 is a circular groove, and the second sliding groove 10 is connected to the first rotating groove 9. One end of the injection cylinder 11 is fixedly connected to the inner wall of the first rotating groove 9 near the second sliding groove 10. The injection cylinder 11 is a hollow plastic cylinder, and adhesive remover can be filled into the injection cylinder 11 from the end away from the fixed cylindrical base 5. The injection cylinder 11 is a container for storing adhesive remover. The cover plate 2... Nine covers are installed at the end of the injection cylinder 11 away from the second gear 24. The cover plate 29 is a circular plastic plate, and a cover groove 32 is formed on the end wall of the cover plate 29 near the injection cylinder 11. The cover groove 32 is a circular groove, and a sealing gasket is provided on the inner wall of the cover groove 32. Since the inner wall contour of the cover groove 32 matches the outer wall contour of the injection cylinder 11, the injection cylinder 11 can maintain a sealing effect with the cover groove 32 after being inserted into the cover groove 32. The sealing gasket is disclosed in the prior art and will not be described in detail. The cover plate 29 can still maintain a seal with the injection cylinder 11 when the end of the injection cylinder 11 away from the second gear 24 rotates. A snap-fit ​​groove 33 is formed on the end wall of the cover plate 29 away from the cover groove 32. The snap-fit ​​groove 33 is a circular groove, and the snap-fit ​​groove 33 is a circular groove. The inner wall of the cover groove 32 is connected to the inner wall of the locking groove 33. Since the inner wall contour of the locking groove 33 matches the outer wall contour of the locking protrusion 23, the C-shaped tube 22 can be bent to apply force and deform along its bending direction. Then, the C-shaped tube 22 can be rotated to align the locking protrusion 23 fixedly connected to the C-shaped tube 22 with the locking groove 33. Then, the force is released, and the C-shaped tube 22 is no longer applied and returns to its original shape along its bending direction, driving the rubber locking protrusion 23 to insert into the locking groove 33. Since the outer wall contour of the locking protrusion 23 matches the inner wall contour of the locking groove 33, when the cover plate 29 rotates, the locking protrusion 23 can maintain the seal between itself and the locking groove 33 without rotating with the cover plate 29. Also, because the first sliding groove 4 is opened... On the outer wall of the handle 1 near the fixed circular base 5, the first sliding groove 4 is a convex groove. The sliding plate 41 is slidably connected to the inner wall of the first sliding groove 4. Since the outer contour of the first sliding groove 4 matches the inner contour of the sliding plate 41, the first sliding groove 4 can slide on the inner wall of the sliding plate 41. One end of the push rod 40 is fixedly connected to the outer wall of the sliding plate 41 near the first gear 7. The push rod 40 is a plastic cylinder, and the outer contour of the push rod 40 matches the inner contour of the second sliding groove 10. Therefore, the push rod 40 can slide on the inner wall of the second sliding groove 10. The end of the push rod 40 away from the sliding plate 41 passes through the inner wall of the second sliding groove 10 and is inserted into the interior of the injection cylinder 11, where a piston 39 is fixedly connected.Piston 39 is existing technology and will not be described in detail. Since the outer contour of piston 39 matches the inner contour of injection cylinder 11, push rod 40 can drive piston 39 to slide on the inner wall of injection cylinder 11. Push plate 42 is fixedly connected to the outer wall of sliding plate 41 on the side away from push rod 40. Push plate 42 is a plastic block with a triangular cross-section, and several anti-slip grooves are linearly arranged on the outer wall of push plate 42 on the side away from handle 1. During use, medical personnel press the anti-slip grooves on push plate 42 with their thumb and push push plate 42 towards fixed round seat 5, causing push plate 42 to slide. The movable plate 41 slides along the inner wall of the first sliding groove 4, thereby pushing the push rod 40 to move along the second sliding groove 10 towards the cover plate 29. The push rod 40 drives the piston 39 to slide synchronously inside the injection cylinder 11, pushing the adhesive remover in the cylinder towards the snap-fit ​​protrusion 23. The adhesive remover flows sequentially through the inner wall of the snap-fit ​​protrusion 23, the inner wall of the C-shaped tube 22, and the inner wall of the L-shaped tube 18. With the above structure, the adhesive remover can be replenished to the inner wall of the L-shaped tube 18 by pushing the push plate 42 without contaminating unused medicine. When the adhesive remover in the injection cylinder 11 is exhausted, it can be quickly replenished by simply removing the cover plate 29 from the end away from the fixed round seat 5, making the operation simple.

[0047] like Figures 1 to 4 and Figures 7 to 9 As shown, a second gear 24 is rotatably connected to the inner wall of the first rotating groove 9. The second gear 24 meshes with the first gear 7. A fourth rotating protrusion 25 is fixedly connected to the outer wall of the second gear 24 near the fixed round seat 5. Several fixed posts 26 arranged in a circular array are fixedly connected to the outer wall of the second gear 24 away from the fourth rotating protrusion 25. A limiting plate 27 is fixedly connected to the end of the fixed post 26 away from the second gear 24. Several limiting grooves 30 are opened on the outer wall of the cover plate 29 near the cover groove 32. A second elastic clamp 31 is fixedly connected to the outer wall of the cover plate 29 near the limiting groove 30. A first elastic clamp 28 is fixedly connected to the outer wall of the second gear 24 near the fixed post 26.

[0048] Specifically, the second gear 24 is rotatably connected to the inner wall of the first rotating groove 9. The second gear 24 is a hollow gear, and its inner wall profile matches the outer wall profile of the injection cylinder 11. Therefore, the second gear 24 can rotate on the outer wall of the injection cylinder 11. Since the second gear 24 meshes with the first gear 7, when the first gear 7 rotates, it will drive the second gear 24 to rotate. The fourth rotating protrusion 25 is fixedly connected to the outer wall of the second gear 24 near the fixed round seat 5. The fourth rotating protrusion 25 is an annular protrusion with a convex overall profile, and its outer wall profile matches the inner wall profile of the first rotating groove 9. Therefore, the fourth rotating protrusion 25 can rotate on the inner wall of the first rotating groove 9. Several fixed posts 26 are fixedly connected to the outer wall of the second gear 24 away from the fourth rotating protrusion 25, and the fixed posts 26 are arranged in a circumferential array. The fixed posts 26 are cylindrical made of plastic. A limiting plate 27 is fixedly connected to the end of the fixed posts 26 away from the second gear 24. The limiting plate 27 is a square plate made of plastic. Several limiting grooves 30 are formed on the outer wall of the cover plate 29 near the cover groove 32, and the limiting grooves 30 are arranged in a circumferential array. The limiting grooves 30 are L-shaped grooves, and the inner wall contour of the limiting grooves 30 matches the outer wall contour formed by the fixed posts 26 and the limiting plate 27. Therefore, the end of the fixed post 26 away from the second gear 24 can be inserted into the limiting groove. Inside the groove 30, the cover plate 29 is rotated to make the fixing post 26 slide along the inner wall of the limiting groove 30. At this time, the outer wall of the limiting plate 27 near the fixing post 26 will abut against the end wall of the cover plate 29 away from the second gear 24. The cooperation of several limiting plates 27 forms a limiting effect on the cover plate 29, keeping the cover plate 29 in the state of being sleeved on the end of the injection cylinder 11 away from the second gear 24, ensuring the sealing effect of the cover groove 32 on the injection cylinder 11. Since one end of the second elastic clip 31 is fixedly connected to the outer wall of the cover plate 29 near the limiting groove 30, and the second elastic clip 31 is an S-shaped plastic plate with the other end being an open end, the second elastic clip 31 can deform along its bending direction after being subjected to force. When the cover plate 29 is in the state of being sleeved on the end of the injection cylinder 11 away from the second gear 24, the outer wall of the second elastic clip 31 will abut against the outer wall of the fixing post 26. Since one end of the first elastic clip 28 is fixedly connected to the outer wall of the second gear 24 near the fixing post 26, and the first elastic clip 28 is an S-shaped plastic plate, the first elastic clip 28 will deform along its bending direction after being subjected to force. It is worth noting that during the process of sleeved on the injection cylinder 11, the second elastic clip 31 on the cover plate 29 needs to be oriented towards the first elastic clip 28. In this way, when preparing to use this device, the outer walls of the second elastic clip 31 and the first elastic clip 28 will abut against the outer wall of the same fixing post 26.

[0049] When using the bandage, medical staff first pinch one end of the elastic bandage. After the bandage separates from the skin to a certain distance, they clamp the two sides of the separated end between the second elastic clip 31 and the corresponding fixation post 26, and between the first elastic clip 28 and the corresponding fixation post 26, respectively. During this process, the first elastic clip 28 and the second elastic clip 31 undergo elastic deformation due to the force, and then, under their own elastic force, they adhere tightly to the outer wall of the fixation post 26, thereby firmly clamping the separated end of the elastic bandage. As the first gear 7 rotates, the second gear 24 meshing with it rotates accordingly, driving... Several fixed posts 26 and cover plates 29 rotate synchronously. The separated end of the clamped elastic bandage gradually wraps around the outer wall of the fixed posts 26 under the rotation of the fixed posts 26. After the elastic bandage wrapped around the outer wall of several fixed posts 26 reaches a certain thickness, the removed elastic bandage can be taken out from several fixed posts 26 and recycled. The above structure can automatically roll up the torn bandage during the process of separating the elastic bandage from the patient's skin, preventing it from falling to the ground and adhering to dust or debris, thereby reducing the cleaning burden of subsequent cleaning personnel.

[0050] like Figures 1 to 3 and Figure 10 As shown, a second rotating protrusion 17 is fixedly connected to the end wall of the roller 14 away from the first rotating protrusion 16. A rotating plate 34 is rotatably connected to the outer wall of the second rotating protrusion 17. A connecting plate 35 is fixedly connected to the outer wall of the rotating plate 34. A support plate 37 is fixedly connected to the side wall of the connecting plate 35. A C-shaped buckle 36 is fixedly connected to the end of the connecting plate 35 away from the rotating plate 34. Specifically, the second rotating protrusion 17 is fixedly connected to the end wall of the roller 14 away from the first rotating protrusion 16. The second rotating protrusion 17 is a convex metal cylinder. The rotating plate 34 is rotatably connected to the outer wall of the second rotating protrusion 17. The rotating plate 34 is a hollow plastic disc. Since the inner wall contour of the rotating plate 34 matches the outer wall contour of the second rotating protrusion 17... Therefore, the rotating plate 34 can rotate on the outer wall of the second rotating protrusion 17. One end of the connecting plate 35 is fixedly connected to the outer wall of the rotating plate 34. The connecting plate 35 is an L-shaped plastic plate. The support plate 37 is fixedly connected to the side wall of the connecting plate 35. The support plate 37 is a square plastic plate. The support plate 37 can provide a guiding effect during the winding of the elastic bandage. The C-shaped buckle 36 is fixedly connected to the end of the connecting plate 35 away from the rotating plate 34. The C-shaped buckle 36 is a C-shaped plastic plate. When the C-shaped buckle 36 is subjected to force, it will deform along its bending direction. Since the inner wall contour of the C-shaped buckle 36 matches the outer wall contour of the C-shaped tube 22, the C-shaped buckle 36 can be snapped onto the outer wall of the C-shaped tube 22.

[0051] Before using this device, medical personnel can rotate the connecting plate 35, causing the rotating plate 34 to rotate along the outer wall of the second rotating protrusion 17 until the C-shaped buckle 36 engages with the outer wall of the C-shaped tube 22. During this process, the C-shaped buckle 36 will be under force and deform along its bending direction until the inner wall of the C-shaped buckle 36 is completely in contact with the outer wall of the C-shaped tube 22. At this point, the C-shaped buckle 36 will no longer be under force and will return to its original shape along its bending direction. The outer wall of the C-shaped buckle 36 near the cover plate 29 will abut against the outer wall of the C-shaped tube 22 near the snap-fit ​​protrusion 23. With the above structure, in use, the C-shaped buckle 36 snaps into the outer wall of the C-shaped tube 22, which can limit the connecting plate 35 and prevent the second rotating protrusion 17 from driving the rotating plate 34 and the connecting plate 35 to rotate synchronously during rotation, thus affecting the support plate 37's support of the elastic bandage after removal. It can also limit the snap-fit ​​protrusion 23 and prevent it from falling out of the inner wall of the snap-fit ​​groove 33.

[0052] The working process of the femoral artery interventional bandage removal auxiliary device provided by the present invention is as follows:

[0053] In the above scheme, during use, medical staff first inject the adhesive remover from the end of the injection cylinder 11 away from the fixed round seat 5. After injection, the cover plate 29 is fitted onto the end of the injection cylinder 11 away from the second gear 24. During installation, the second elastic clip 31 on the cover plate 29 must face the first elastic clip 28, and the ends of several fixing posts 26 away from the second gear 24 are respectively inserted into the corresponding limiting grooves 30. Then, the cover plate 29 is rotated to make the fixing posts 26 slide along the inner wall of the limiting grooves 30, so that the limiting plate 27 is close to the side of the fixing posts 26. The outer wall abuts against the outer wall of the cover plate 29 on the side away from the second gear 24. Under the coordinated action of multiple limiting plates 27, the cover plate 29 is limited, making it stably fitted onto the end of the injection cylinder 11. Then, the medical staff bends the C-shaped tube 22, causing it to be stressed and undergo elastic deformation along its bending direction. Subsequently, the C-shaped tube 22 is rotated so that the snap-fit ​​protrusion 23 aligns with the snap-fit ​​groove 33. After being released, the C-shaped tube 22 resets under the action of elastic restoring force, and drives the rubber snap-fit ​​protrusion 23 to insert into the snap-fit ​​groove 33, achieving a sealed connection.

[0054] During operation, the medical staff holds the handle 1 with one hand, places the outer wall of the roller 14 between the patient's skin and the elastic bandage, and then presses the button 3 with the index finger to start the motor inside the handle 1. The motor drives the output shaft to rotate, which drives the first gear 7 and the pulley 8 to rotate synchronously. Driven by the belt 38, the roller 14 rotates together with the pulley 8. As the roller 14 rotates, the elastic bandage can be gradually separated from the patient's skin.

[0055] Meanwhile, medical staff use their other hand to hold one end of the elastic bandage. After the bandage separates from the skin to a certain distance, they clamp the two sides of the separated end between the second elastic clip 31 and the corresponding fixing post 26, and between the first elastic clip 28 and the corresponding fixing post 26, respectively. During this process, the first elastic clip 28 and the second elastic clip 31 undergo elastic deformation due to force. Then, under their own elastic force, they adhere tightly to the outer wall of the fixing post 26, thereby firmly clamping the separated end of the elastic bandage. As the first gear 7 rotates, the second gear 24 meshing with it rotates accordingly, driving several fixing posts 26 and cover plates 29 to rotate synchronously. The clamped separated end of the elastic bandage gradually wraps around the outer wall of the fixing post 26 under the rotation action of the fixing post 26.

[0056] While the roller 14 separates the bandage, medical staff press the anti-slip groove on the push plate 42 with their thumbs and push the push plate 42 towards the fixed round seat 5. The push plate 42 drives the sliding plate 41 to slide along the inner wall of the first sliding groove 4, which in turn pushes the push rod 40 to move along the second sliding groove 10 towards the cover plate 29. The push rod 40 drives the piston 39 to slide synchronously in the injection cylinder 11, squeezing the adhesive remover in the cylinder towards the snap-fit ​​protrusion 23. The adhesive remover flows sequentially through the inner wall of the snap-fit ​​protrusion 23 and the C-shaped round tube 22. The inner wall of the L-shaped tube 18 is then evenly coated onto the outer wall of the roller 14 via the infusion tank 21. With the rotation of the roller 14, the adhesive remover is evenly applied between the elastic bandage and the skin, further promoting their separation. During the separation process, the adhesive dissolved by the adhesive remover may adhere to the outer wall of the roller 14. At this time, the scraper plate 20, which is against the outer wall of the roller 14, can scrape off the adhered adhesive in time to prevent it from affecting the coating effect of the subsequent adhesive remover. When too much adhesive accumulates on the scraper plate 20, it can be cleaned with gauze.

[0057] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
