Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a urinary catheter limiter for patients after kidney transplantation. Background Art

[0002] For patients after kidney transplantation, usually the patients need to stay in bed for recuperation, and at the same time, they need to insert a urinary catheter to divert the urine in the bladder. Usually, the urinary catheter needs to be fixed to avoid pulling during the patient's turning over or moving.

[0003] As disclosed in a utility model with the authorization announcement number CN208747725U, a urinary catheter limiter for postoperative care of kidney transplantation, which includes a plastic fixing plate. One side of the plastic fixing plate is provided with a U-shaped groove. A first clamping plate is fixedly connected to the plastic fixing plate. A second clamping plate is rotatably connected to the first clamping plate. A clamping component is arranged between the first clamping plate and the second clamping plate. An adjustable arc-shaped clamping block is slidably connected in both the first clamping plate and the second clamping plate. A protective block is fixedly connected to the second clamping plate. A fixing groove is opened on the first clamping plate below the protective block. This solution solves the problem that the conventional urinary catheter after kidney transplantation lacks a fixing device and is easily pulled during the catheterization period, resulting in the movement of the urinary catheter, affecting the subsequent urinary catheterization work and increasing the workload of medical staff.

[0004] However, the above solution has the following problems: When the urinary catheter is fixed, since the urinary catheter extends out of the body for a long distance, when the kidney transplantation patient turns over or moves the legs, it is easy to cause the urinary catheter to be pulled. By fixing both ends, the influence of the pulling force on the urinary catheter is prevented, and the probability of the patient suffering from urinary tract infection is prevented. The above solution cannot simultaneously fix the end part and the lower part of the urinary catheter. The upper part and the lower part of the urinary catheter are fixed separately, which is inconvenient for medical staff to perform the fixing operation, and the urinary catheter cannot be quickly relaxed, which is not convenient for subsequent disassembly of the urinary catheter. Therefore, we propose a urinary catheter limiter for patients after kidney transplantation. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-4 , the present invention provides a technical solution: a catheter limiter for patients after kidney transplantation, including a base 3, a cover plate 6 is arranged on one side of the base 3, an adhesive part 2 is arranged on one side of the base 3. Specifically, the adhesive part 2 is replaceable, and the device can be recycled. The device can be adhesively fixed to the skin of the patient through the adhesive part. An installation port 7 is arranged on one side of the base 3, an end locking mechanism 1 is arranged in the installation port 7, and an opposite locking mechanism 4 for tensioning the catheter is also arranged on one side of the cover plate 6.

[0038] The end locking mechanism 1 includes a longitudinal rack 103. The longitudinal rack 103 is movably arranged on one side inside the base 3. The longitudinal rack 103 meshes with the upper gear 107. By the movement of the upper gear 107 and the longitudinal rack 103, the movement of the longitudinal rack 103 can be controlled. The upper gear 107 is arranged on one side of the support sleeve 109. The support sleeve 109 is rotatably arranged on one side inside the base 3. Specifically, a plum blossom handwheel 108 is also arranged on the support sleeve 109. By rotating the plum blossom handwheel 108, the rotation direction of the support sleeve 109 can be controlled. One side surface of the longitudinal rack 103 is provided with a connecting rod 102. One end of the connecting rod 102 is connected to the upper clamping plate 101. The upper clamping plate 101 is movably arranged in the installation opening 7. A lower clamping plate 115 corresponding to the upper clamping plate 101 is also arranged on one side inside the installation opening 7. Through the arrangement of the upper clamping plate 101 and the lower clamping plate 115, the end of the catheter can be clamped and fixed.

[0039] Place the catheter on both sides of the upper tension rod 403 and the lower tension rod 408, then pass it through the gap between the upper clamping plate 101 and the lower clamping plate 115, and place the catheter into the patient's bladder. Then place the catheter into the lower limit sleeve 5 and close the lower limit sleeve 5. Then rotate the plum blossom handwheel 108. The plum blossom handwheel 108 drives the support sleeve 109 to rotate. The support sleeve 109 drives the upper gear 107 to rotate. The rotation of the upper gear 107 drives the longitudinal rack 103 to move downward. The longitudinal rack 103 drives the upper clamping plate 101 to move downward through the connecting rod 102. When the upper clamping plate 101 and the lower clamping plate 115 are in contact with the catheter, the upper clamping plate 101 and the lower clamping plate 115 clamp and fix the end of the catheter.

[0040] Furthermore, a guiding slider 113 is arranged on one side of the outer surface of the upper clamping plate 101. One end of the guiding slider 113 is slidably arranged in the guiding chute 114. The guiding chute 114 is arranged on the other side surface inside the installation opening 7. When the upper clamping plate 101 moves, it can drive the guiding slider 113 to move in the guiding chute 114, ensuring the stability of the movement of the lower clamping plate 115. At the same time, both the upper clamping plate 101 and the lower clamping plate 115 are arc-shaped structures, increasing the contact area with the end of the catheter and further improving the clamping stability.

[0041] Furthermore, an upper arc-shaped anti-slip pad 112 is arranged inside the upper clamping plate 101, and a lower arc-shaped anti-slip pad 116 is arranged inside the lower clamping plate 115. When the upper clamping plate 101 and the lower clamping plate 115 are in contact with the end of the catheter, the upper arc-shaped anti-slip pad 112 and the lower anti-slip pad are in contact with the end of the catheter, which can improve the stability of the fixation of the end of the catheter.

[0042] Furthermore, one end of the connecting rod 102 is movably arranged in the adjusting opening 111. The adjusting opening 111 is arranged on one side inside the installation opening 7. The movement of the longitudinal rack 103 drives the connecting rod 102 to move in the adjusting opening 111 and guides the movement of the connecting rod 102.

[0043] Further, a longitudinal slider 104 is also arranged on one side of the longitudinal rack 103. The longitudinal slider 104 is slidably arranged in the longitudinal chute 105. The longitudinal chute 105 is arranged on one side surface of the support base 106. The support base 106 is arranged on the inner side of the base 3. Driven by the upper gear 107, the longitudinal rack 103 drives the longitudinal slider 104 to move in the longitudinal chute 105.

[0044] Please refer to Figure 2 、 Figure 3 and Figure 5 , the opposing locking mechanism 4 includes an upper tension rod 403 and a lower tension rod 408. An upper mounting rod 405 is arranged on one side of the upper tension rod 403. An upper transverse rack 404 is arranged at one end of the upper mounting rod 405. A lower mounting rod 407 is arranged on one side of the lower tension rod 408. A lower transverse rack 406 is arranged at one end of the lower mounting rod 407. Both the upper transverse rack 404 and the lower transverse rack 406 are engaged with the lower gear 401. The lower gear 401 is arranged on the lower rotating shaft 402. By rotating the lower gear 401, the upper transverse rack 404 and the lower transverse rack 406 can be simultaneously driven to move in opposite directions, and the catheter is tensioned and fixed.

[0045] When the support sleeve 109 is driven to rotate by the plum blossom handwheel 108, the support sleeve 109 drives the upper belt pulley 110 to rotate. The upper belt pulley 110 drives the double-row belt pulley 118 to rotate through the synchronous belt. The double-row belt pulley 118 drives the bearing shaft 117 to rotate. The double-row belt pulley 118 drives the lower belt pulley 119 to rotate through the synchronous belt again. The lower belt pulley 119 drives the lower rotating shaft 402 to rotate. The lower rotating shaft 402 drives the lower gear 401 to rotate. Furthermore, the upper gear 107 and the lower gear 401 can be controlled to rotate synchronously and in the same direction. Through the synchronous rotation of the upper gear 107 and the lower gear 401, while synchronously controlling the lower clamping plate 115 to move downward, the upper tension rod 403 and the lower tension rod 408 can be simultaneously driven to move in opposite directions, and the end and the lower part of the catheter are fixed simultaneously.

[0046] Further, please refer to Figure 6 , annular clamping grooves 409 are arranged on both the upper tension rod 403 and the lower tension rod 408. During the clamping process of the catheter, the catheter is clamped into the annular clamping grooves 409 of the upper tension rod 403 and the lower tension rod 408, further improving the clamping stability of the catheter.

[0047] Please refer to 3 and Figure 5, the support sleeve 109 is connected to the opposing mechanism through a synchronous transmission structure. The synchronous transmission structure includes an upper pulley 110, which is arranged on one side of the support sleeve. The upper pulley 110 is connected to a double-row pulley 118 through a synchronous belt. The double-row pulley 118 is arranged on one side of the bearing shaft 117. The bearing shaft 117 is rotatably arranged on one side inside the base 3. The double-row pulley 118 is connected to a lower pulley 119 through a synchronous belt. The lower pulley 119 is arranged on one side of the lower rotating shaft 402. Through the setting of the synchronous transmission structure, the upper gear 107 and the lower gear 401 can be controlled to rotate synchronously.

[0048] When the support sleeve 109 rotates, the support sleeve 109 drives the lower rotating shaft 402 to rotate through the synchronous transmission structure. The lower rotating shaft 402 drives the lower gear 401 to rotate. The lower gear 401 drives the upper horizontal rack 404 and the lower horizontal rack 406 to move oppositely. The upper horizontal rack 404 and the lower horizontal rack 406 drive the upper tensioning rod 403 and the lower tensioning rod 408 to move oppositely through the upper mounting rod 405 and the lower mounting rod 407. Furthermore, the upper tensioning rod 403 and the lower tensioning rod 408 can tension the lower part of the catheter to prevent the lower part of the catheter from loosening.

[0049] Further, please refer to Figure 7 and Figure 8 , the upper mounting rod 405 is movably arranged in the upper limit port 8, and the lower mounting rod 407 is movably arranged in the lower limit port 9. The upper limit port 8 and the lower limit port 9 are arranged on one side of the cover body. When the upper mounting rod 405 and the lower mounting rod 407 move, the moving positions of the upper mounting rod 405 and the lower mounting rod 407 can be guided. A lower limit sleeve 5 that can be opened and closed is also arranged on the cover plate 6 for positioning and installing the lower part of the catheter.

[0050] Please refer to Figure 9 and Figure 10 , an automatic limiting mechanism for positioning the clamping position is also arranged inside the support sleeve 109. The automatic limiting mechanism includes a pressing rod 301 that is wider at the top and narrower at the bottom. The pressing rod 301 is movably arranged inside the support sleeve 109. One end of the pressing rod 301 is movably arranged inside the bearing sleeve 303. The bearing sleeve 303 is arranged inside the base 3. A limiting disk 304 is arranged at the bottom of the pressing rod 301. A first spring 302 is also arranged inside the bearing sleeve 303. One end of the first spring 302 is connected to the limiting disk 304. A torsion spring 120 is also arranged on the outer surface of the support sleeve 109. A clamping component for positioning the support sleeve 109 is also arranged inside the bearing sleeve 303, which can position the rotation position of the support sleeve 109.

[0051] The clamping component includes a horizontal fixing pin 308 which is movably arranged on one side of the bearing sleeve 303. One end of the horizontal fixing pin 308 is clamped in the clamping groove 309. The clamping grooves 309 are evenly arranged in a ring on the inner wall of the support sleeve 109. A horizontal wedge block 306 is also arranged at the other end of the horizontal fixing pin 308. The horizontal wedge block 306 abuts against the vertical wedge block 305. The vertical wedge block 305 is arranged on one side of the pressing rod 301. A second spring 307 is also sleeved on the outer surface of the horizontal fixing pin 308. One end of the second spring 307 is connected to the inner wall of the bearing sleeve 303, and the other side of the second spring 307 is connected to the horizontal wedge block 306. When the horizontal fixing pin 308 moves into the corresponding clamping groove 309, it can automatically fix the support sleeve 109.

[0052] When rotating the support sleeve 109, hold down the pressing rod 301. The pressing rod 301 drives the limiting disc 304 to move downward. The limiting disc 304 compresses the first spring 302. At the same time, the second spring 307 drives the horizontal fixing pin 308 to move and makes the horizontal fixing pin 308 move out of the clamping groove 309. Then rotate the support sleeve 109. The support sleeve 109 drives the clamping groove 309 to rotate. When both the end and the lower part of the catheter are fixed, release the pressing rod 301. The first spring 302 drives the pressing rod 301 to move back. The pressing rod 301 drives the vertical wedge block 305 to move. The vertical wedge block 305 drives the horizontal wedge block 306 to move. The movement of the horizontal wedge block 306 drives the horizontal fixing pin 308 to move back and clamps the horizontal fixing pin 308 into the corresponding clamping groove 309, thereby locking the position of the support sleeve 109. At the same time, the rotation of the support sleeve 109 can drive the torsion spring 120 to rotate.

[0053] When the catheter needs to be disassembled, press the pressing rod 301 to separate the vertical wedge block 305 from the horizontal wedge block 306. The second spring 307 drives the horizontal fixing pin 308 to move back and separates the horizontal fixing pin 308 from the clamping groove 309. The torsion spring 120 drives the support sleeve 109 to rotate back. The rotation back of the support sleeve 109 drives the upper gear 107 to rotate back. At the same time, through the synchronous transmission structure, it drives the lower rotating shaft 402 to rotate back. The lower rotating shaft 402 drives the lower gear 401 to rotate back. Thus, the longitudinal rack 103 drives the upper clamping plate 101 to separate from the catheter. At the same time, the upper tension rod 403 and the lower tension rod 408 move back towards each other and loosen the lower part of the catheter, facilitating the rapid disassembly of the catheter.

[0054] Please refer to Figures 11-13, a buffer structure is further provided on one side of the cover plate 6. The buffer structure includes a buffer rod 61. The buffer rod 61 is provided on one side of a transverse buffer block 62. The transverse buffer block 62 is arranged in a transverse chute 64. The transverse chute 64 is provided on one side of the cover plate 6. A buffer spring 63 is arranged on one side inside the transverse chute 64. One end of the buffer spring 63 is connected to the transverse buffer block 62. After the upper and lower ends of the catheter are fixed, one end of the diversion tube is attached to the buffer rod, and one end of the catheter is placed in the lower limit sleeve 5. The other end of the catheter is connected to the urine bag. When the patient turns over or moves the legs, the catheter is pulled, which will drive the buffer rod 61 to move. The buffer rod 61 drives the transverse buffer block 62 to move in the transverse chute 64. The transverse buffer block 62 compresses the buffer spring 63. The buffer spring 63 can absorb the pulling force and prevent the problem that the fixed part of the catheter is pulled.
