Description

Technical Field

[0001] This invention relates to the technical field of urological instruments, and in particular to a urinary catheter with a fixation component. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber, or polyvinyl chloride. After the catheter is inserted into the bladder, a balloon near the tip of the catheter secures it in the bladder, preventing it from easily falling out. The drainage tube is connected to a urine bag to collect urine. When using a urinary catheter, a fixing component is required to secure the catheter.

[0003] Existing urinary catheters, through the structural design of the fixation mechanism, can effectively secure the catheter, preventing it from detaching from the patient, ensuring its use, and improving the user experience.

[0004] However, in actual use, the distance between the urinary catheter and the patient's bladder in existing technologies is often too long or too short. This not only affects the quality of medical care, but also, when the urinary catheter is too short, it can cause the patient to lose awareness due to movement, or even cause the catheter to fall off the patient's bladder.

[0028] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0029] Reference Figures 1-8 This invention discloses a urinary catheter with a fixing component, including a sleeve 1 and a catheter body 2. A storage structure is provided on the right side of the sleeve 1, and tube insertion structures are provided on both the left and right sides of the storage structure. A clamping structure is provided on the left side of the sleeve 1, and binding structures are provided on the front and rear sides of the sleeve 1. The storage structure includes two sets of longitudinal grooves 3 formed on the front and rear sides of the sleeve 1, spaced apart from each other. A first moving block 4 is slidably disposed in the longitudinal groove 3. The moving block 4 is rotatably connected to the middle of a first rotating shaft 5. A first pulley 6 is fixedly sleeved on the first rotating shaft 5. The conduit body 2 passes around each of the first pulleys 6. A first adjustment structure is provided in the middle of the sleeve plate 1. The conduit structure includes two U-shaped frames 7 fastened to the sleeve plate 1 by screws. Two second rotating shafts 8 are rotatably passed through the U-shaped frames 7 near the middle. The bottom end of the second rotating shafts 8 is rotatably connected to the sleeve plate 1. A second pulley 9 is fixedly sleeved on the second rotating shafts 8. The conduit body 2 passes through the space between each set of two second pulleys 9.

[0030] The first adjustment structure includes a transverse groove 10 located in the middle of the right side of the sleeve plate 1. A screw 11 is rotatably connected to the left end wall of the transverse groove 10. The screw 11 rotates out of the right end of the sleeve plate 1. A turntable 12 is fixedly fitted on the right end of the screw 11. A second moving block 17 is fitted on the screw 11. The second moving block 17 has threads for the screw 11 to pass through. Insert rods 16 are connected to both the front and rear sides of the second moving block 17. The insert rods 16 are "U" shaped. A drive plate 13 is provided on both the front and rear sides of the transverse groove 10 on the sleeve plate 1. The drive plate 13 has a push-pull groove 14. The left section of the push-pull groove 14 is "Z" shaped. One end of the insert rod 16 is movably inserted into the push-pull groove 14. The drive plate 13 is connected to the first moving block 4 through a connecting strip 15, which moves the guide tube body 2 from the two sets of second sliding... The catheter body 2 passes between the first pulleys 9 and around each of the first pulleys 6. After the urinary catheter is secured to the patient's leg by the binding structure on the sleeve plate 1, the screw 11 can be rotated using the turntable 12. The second moving block 17 moves in the transverse groove 10, causing one end of the insertion rod 16 to move in the push-pull groove 14 on the drive plate 13. The insertion rod 16 squeezes the groove wall of the push-pull groove 14, thereby moving the corresponding first pulley 6. By adjusting the distance between the two sets of first pulleys 6 on the sleeve plate 1, the storage length of the catheter body 2 on the sleeve plate 1 can be adjusted. In this way, the clamping and fixing position and distance from the patient's bladder on the catheter body 2 can be flexibly adjusted according to the actual needs, reducing the problem of the catheter body 2 being too long or too short.

[0031] See Figure 1 and Figure 3 The clamping structure includes a fixed frame 42 located on the left side of the sleeve plate 1. The fixed frame 42 has two through slots 18. A fixed rod 19 is connected between the front and rear end walls of the through slots 18. A third moving block 20 is movably sleeved on the fixed rod 19. A clamping sleeve 24 is connected below the third moving block 20. A first spring 23 is sleeved on the fixed rod 19. The two ends of the first spring 23 are respectively connected to one end wall of the through slot 18 and the third moving block 20. A connecting plate 21 is connected to the third moving block 20. A pressing piece 22 is provided on one end of the two connecting plates 21 that are far apart from each other. An anti-deformation structure is provided on the guide tube body 2.

[0032] The anti-deformation structure includes multiple enlarging tubes 25 set on the catheter body 2. The multiple enlarging tubes 25 are evenly distributed. Each enlarging tube 25 has a rigid tube fixedly installed on its inner wall. Two clips 24 are clamped on the enlarging tube 25. When clamping the catheter body 2 on the sleeve plate 1, the medical staff only needs to press the two pressing pieces 22 towards the middle, which will drive the two clips 24 to move away from each other. After the catheter body 2 passes between the two clips 24, the two pressing pieces 22 are released. Under the elastic force of the first spring 23, the two clips 24 are pushed back to their original position and clamped onto the corresponding enlarging tube 25. The catheter body 2 can be clamped and fixed on the sleeve plate 1. The rigid tube on the inner wall of the enlarging tube 25 can prevent the catheter body 2 from being compressed and deformed during the clamping process, which would affect the patient's normal urination.

[0033] See Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The fastening structure includes a first strap 26 connected to the front and rear sides of the sleeve 1, a second strap 27 provided on the first strap 26 through a second adjustment structure, a first Velcro 28 provided on the inner wall of the second strap 27 away from the first strap 26, and a second Velcro 29 provided on the rear side of the sleeve 1.

[0034] The second adjustment structure includes a cylindrical tube 30 located between the first strap 26 and the second strap 27. A soft pad 33 is provided on the outer surface of the cylindrical tube 30. Two through slots 31 are provided on the cylindrical tube 30. Two rollers are rotatably connected between the two ends of each through slot 31. The first strap 26 and the second strap 27 pass through the two rollers of each group respectively. An adjustment rod 32 rotatably passes through the cylindrical tube 30. The first strap 26 and the second strap 27 are close to each other and connected to the adjustment rod 32 at one end. The end of the adjustment rod 32 that extends out of the cylindrical tube 30 is provided with a rotating block 36 through a positioning structure. A handle 37 is installed on the rotating block 36.

[0035] The positioning structure includes a limiting plate 40 fixedly sleeved on one end of the adjusting rod 32 that rotatably protrudes from the circular cylinder 30. A square rod 39 is fixedly connected to the middle of one side of the limiting plate 40. A first fixed cylinder 34 is connected to one side edge of the limiting plate 40. 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 limiting plate 40. A second fixed cylinder 35 is connected to one side of the rotating block 36. 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 the catheter body 2 is installed, the sleeve 1 is placed on the patient's leg and secured to the patient's leg with the first strap 26 and the second strap 27. After securing, the second fixing cylinder 35 can be pulled out from the first fixing cylinder 34 by using the handle 37 to pull the rotating block 36. The positioning of the adjusting rod 32 on the circular cylinder 30 is released. Then, the adjusting rod 32 is rotated by using the handle 37. By winding or releasing the first strap 26 and the second strap 27 inside the circular cylinder 30, the tightness of the binding can be flexibly adjusted on the patient's leg without the need for re-tightening, making it more convenient to use.

[0036] The implementation principle of a urinary catheter with a fixing component according to an embodiment of the present invention is as follows: First, the catheter body 2 is passed between two sets of second pulleys 9 and around each first pulley 6. Then, the sleeve 1 is tightly fixed to the patient's leg by the first binding strap 26 and the second binding strap 27. After being fixed, the handle 37 is used to pull the rotating block 36 to pull the second fixing cylinder 35 out of the first fixing cylinder 34. The positioning of the adjusting rod 32 on the circular cylinder 30 is released. Then, the handle 37 is used to rotate the adjusting rod 32. By winding or releasing the first binding strap 26 and the second binding strap 27 in the circular cylinder 30, the tightness of the binding can be flexibly adjusted on the patient's leg without re-tightening, making it more convenient to use. Next, the turntable 12 is used to rotate the screw 11, 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. The catheter body 2 is moved by the compression of the push-pull groove 14 wall by the insertion rod 16, which drives the corresponding first pulley 6 to move. By adjusting the distance between the two sets of first pulleys 6 on the sleeve plate 1, the catheter body 2 is pulled so that it is tightly wrapped around the first pulley 6. Then, the medical staff presses the two pressing pieces 22 towards the center on the fixing frame 42, which drives the two clamps 24 to move away from each other. After the catheter body 2 passes between the two clamps 24, the two pressing pieces 22 are released. Under the elastic force of the first spring 23, the two clamps 24 are pushed back to their original position and clamped onto the corresponding enlargement tube 25. The catheter body 2 is then clamped and fixed on the sleeve plate 1. In this way, the distance between the fixed position of the catheter body 2 and the patient's bladder and the length of the catheter body 2 can be flexibly adjusted according to the actual needs, reducing the problem of catheter body 2 detachment and improving the quality of medical care.

[0037] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
