Detailed implementation manners

[0028] The following further elaborates on the present invention Figures 1 - 8 in conjunction with the attached drawings.

[0029] Referring to Figures 1 - 8 , an embodiment of the present invention discloses a urinary catheter with a fixing assembly, including a sleeve plate 1 and a catheter main body 2. A storage structure is arranged at the right side on the upper surface of the sleeve plate 1. Tube guiding structures are arranged on both the left and right sides of the storage structure on the upper surface of the sleeve plate 1. A clamping structure is arranged at the left position on the upper surface of the sleeve plate 1. Tightening structures are arranged on the front and rear side surfaces of the sleeve plate 1; the storage structure includes two groups of longitudinal grooves 3 opened at the front and rear sides on the upper surface of the sleeve plate 1. The two groups of longitudinal grooves 3 are arranged at intervals. A first moving block 4 is slidably arranged in the longitudinal groove 3. A first rotating shaft 5 is rotatably connected to the middle of the upper surface of the first moving block 4. A first pulley 6 is fixedly sleeved on the first rotating shaft 5. The catheter main body 2 bypasses each first pulley 6. A first adjusting structure is arranged at the middle of the sleeve plate 1; the tube guiding structure includes two U-shaped frames 7 fastened to the upper surface of the sleeve plate 1 by screws. Two second rotating shafts 8 rotatably pass through near the middle of the U-shaped frame 7. The bottom ends of the second rotating shafts 8 are rotatably connected to the sleeve plate 1. A second pulley 9 is fixedly sleeved on the second rotating shaft 8. The catheter main body 2 passes between two second pulleys 9 in each group;

[0030] The first adjustment structure includes a transverse groove 10 opened at the middle of the right side on the upper surface of the sleeve plate 1. A screw rod 11 is rotatably connected to the left end groove wall of the transverse groove 10. The screw rod 11 rotates and passes through the right end of the sleeve plate 1. A turntable 12 is fixedly sleeved on the right end of the screw rod 11. A second moving block 17 is sleeved on the screw rod 11. A thread for the screw rod 11 to pass through is opened on the second moving block 17. Plug rods 16 are connected to the front and rear sides of the upper surface of the second moving block 17. The plug rods 16 are in a "U" shape. Driving plates 13 are arranged on the upper surface of the sleeve plate 1 at the front and rear sides of the transverse groove 10. A push-pull groove 14 is opened on the driving plate 13. The left section of the push-pull groove 14 is in a "Z" shape. One end of the plug rod 16 is movably inserted into the push-pull groove 14. The driving plate 13 is connected to the first moving block 4 through a connecting bar 15. The catheter main body 2 is passed through between the two second pulleys 9, and the catheter main body 2 is wound around each first pulley 6. After the urinary catheter is tied and fixed to the patient's leg through the tying structure on the sleeve plate 1, the screw rod 11 can be rotated by using the turntable 12. The second moving block 17 moves in the transverse groove 10, driving one end of the plug rod 16 to move in the push-pull groove 14 on the driving plate 13. By the extrusion of the plug rod 16 on the groove wall of the push-pull groove 14, the corresponding first pulley 6 is driven to move. By adjusting the distance between the two first pulleys 6 on the sleeve plate 1, the storage length of the catheter main body 2 on the sleeve plate 1 is adjusted. In this way, according to the actual needs, the clamping and fixing position on the catheter main body 2 and the length of the catheter main body 2 used to the patient's bladder can be flexibly adjusted, reducing the problems of the catheter main body 2 being too long or too short.

[0031] See Figure 1 and Figure 3 , the clamping structure includes a fixed frame 42 arranged at the left side on the upper surface of the sleeve plate 1. Two through grooves 18 are opened on the upper surface of the fixed frame 42. A fixed rod 19 is connected between the front and rear end groove walls of the through groove 18.

A connecting plate 21 is connected to the third moving block 20. Pressing pieces 22 are arranged at the mutually separated ends of the two connecting plates 21. An anti-deformation structure is arranged on the catheter main body 2;

[0032] The anti-deformation structure includes multiple enlarging tubes 25 arranged on the catheter body 2. The multiple enlarging tubes 25 are evenly distributed. A rigid tube is fixedly arranged on the inner wall of each enlarging tube 25. Two clamping sleeves 24 are clamped on the enlarging tube 25. When the medical staff clamps the catheter body 2 on the sleeve plate 1, they only need to press the two pressing pieces 22 towards the middle, driving the two clamping sleeves 24 to move away from each other. After passing the catheter body 2 through the two clamping sleeves 24, they only need to release the two pressing pieces 22. Under the elastic force of the first spring 23, the two clamping sleeves 24 are pushed to reset, and the two clamping sleeves 24 are clamped on the corresponding enlarging tubes 25, so that the catheter body 2 can be clamped and fixed on the sleeve plate 1. Moreover, the setting of the rigid tube on the inner wall of the enlarging tube 25 can avoid the problem that the catheter body 2 is compressed and deformed during the clamping process, which affects the normal urination of the patient.

[0033] See Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the tying structure includes a first strap 26 connected to the front and rear sides of the sleeve plate 1. A second strap 27 is arranged on the first strap 26 through a second adjustment structure. A first magic tape 28 is arranged on the inner wall of the second strap 27 on the side far from the first strap 26, and a second magic tape 29 is arranged on the rear side of the sleeve plate 1;

[0034] The second adjustment structure includes a circular cylinder 30 arranged in the middle of the first strap 26 and the second strap 27. A soft pad 33 is arranged on the outer side of the circular cylinder 30. Two through grooves 31 are opened on the circular cylinder 30. Two rollers are rotatably connected between the two end walls of each through groove 31. The first strap 26 and the second strap 27 respectively pass through between each group of two rollers. An adjustment rod 32 is rotatably passed through the circular cylinder 30. One ends of the first strap 26 and the second strap 27 close to each other are connected to the adjustment rod 32. A rotating block 36 is arranged at one end of the adjustment rod 32 passing through the circular cylinder 30 through a positioning structure, and a handle 37 is installed on the rotating block 36;

[0035] The positioning structure includes a limit disk 40 fixedly sleeved on one end of the adjusting rod 32 that rotates through the circular cylinder 30. In the middle of one side surface of the limit disk 40, a square rod 39 is fixedly connected. At the edge of one side of the limit disk 40, a first fixed cylinder 34 is connected. A square cylinder 38 is movably sleeved on the square rod 39. One end of the square cylinder 38 is connected to the rotating block 36. A second spring 41 is connected between the square cylinder 38 and the limit disk 40. On one side surface of the rotating block 36, a second fixed cylinder 35 is connected. The second fixed cylinder 35 is movably inserted into the first fixed cylinder 34. Both the second fixed cylinder 35 and the first fixed cylinder 34 are polygonal cylinders. After installing the catheter main body 2 on the sleeve plate 1, the sleeve plate 1 is sleeved on the patient's leg, and through the first strap 26 and the second strap 27, the sleeve plate 1 is tightly tied and fixed to the patient's leg. After being tightly tied and fixed, the rotating block 36 can be pulled by the handle 37 to pull out the second fixed cylinder 35 from the first fixed cylinder 34, and the positioning of the adjusting rod 32 on the circular cylinder 30 is released. Then, the adjusting rod 32 is rotated by the handle 37 to wind or release the first strap 26 and the second strap 27 in the circular cylinder 30, so that the tightness of the tie can be flexibly adjusted on the patient's leg without re-tightening, which is more convenient to use.

[0036] The implementation principle of a urinary catheter with a fixing component in an embodiment of the present invention is as follows: First, pass the catheter body 2 through between two groups of second pulleys 9, and wind the catheter body 2 around each first pulley 6. Then, use the first strap 26 and the second strap 27 to tightly fasten and fix the sleeve plate 1 to the patient's leg. After tightening and fixing, pull the rotating block 36 with the handle 37 to extract the second fixing cylinder 35 from the first fixing cylinder 34, release the positioning of the adjusting rod 32 on the circular cylinder 30, and then rotate the adjusting rod 32 with the handle 37. By winding or releasing the first strap 26 and the second strap 27 in the circular cylinder 30, the tightness of the fastening can be flexibly adjusted on the patient's leg without re-tightening, making it more convenient to use. Then, rotate the screw 11 with the turntable 12, and the second moving block 17 moves in the transverse groove 10, driving one end of the insertion rod 16 to move in the push-pull groove 14 on the driving plate 13. By the extrusion of the insertion rod 16 on the groove wall of the push-pull groove 14, the corresponding first pulley 6 is driven to move. By adjusting the distance between the two groups of first pulleys 6 on the sleeve plate 1, and then pulling the catheter body 2, the catheter body 2 is wound tightly around the first pulley 6. Next, the medical staff presses the two pressing pieces 22 towards the middle in the fixing frame 42, driving the two clamping sleeves 24 to move away from each other. After passing the catheter body 2 between the two clamping sleeves 24, then release the two pressing pieces 22. Under the elastic force of the first spring 23, the two clamping sleeves 24 are pushed to reset, and the two clamping sleeves 24 are clamped to the corresponding enlarged tubes 25, clamping and fixing the catheter body 2 on the sleeve plate 1. In this way, according to the actual needs, the position of the catheter body 2 fixed relative to the patient's bladder and the length of the catheter body 2 used can be flexibly adjusted, reducing the problem of the catheter body 2 coming off and improving the medical quality.

[0037] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
