Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a dialysis tube repositioning device. Background Technology

[0002] Peritoneal dialysis patients need to have dialysis catheters left in their bodies for a long time. Dialysis catheters have two functions: during dialysis, they introduce dialysate into the peritoneal cavity, and after dialysis, they drain the body fluids out of the body. Dialysis catheters left in the body are prone to floating due to the peritoneal dialysis fluid and intestinal peristalsis. Floating catheters can lead to obstructed drainage of peritoneal dialysis fluid, so it is necessary to reposition the dialysis catheter after it floats.

[0003] For the repositioning of dialysis catheters, the prior art CN220656070U proposes a peritoneal dialysis catheter repositioning device. This device utilizes a flexible head, which can be inserted into the dialysis catheter during use, and then the dialysis catheter can be repositioned using the flexible head.

[0004] However, the aforementioned device uses a pull rope to bend the head of the device during operation, and the bending direction is uncontrollable. Furthermore, after bending, the bent part cannot be actively restored to a straight line or the bending amplitude cannot be adjusted by operating the handle, which greatly limits its use. In addition, the aforementioned device bends the head of the device by rotating the tail, which is not convenient to operate. To address the above problems, we provide a dialysis tube resetting device to solve the aforementioned issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 In this embodiment of the present invention, a dialysis tube resetting device includes a hollow handle 1. A hollow guide rod 4 is fixedly connected to one end of the hollow handle 1. A plurality of chain segments 6 are provided at the end of the hollow guide rod 4 away from the hollow handle 1. A hinge plate 14 is fixedly connected to one end of each chain segment 6. The chain segments 6 are hinged together end to end by the hinge plate 14. An end 5 is also hinged to the end of one chain segment 6 away from the hollow guide rod 4. The end of the end 5 is arc-shaped. The chain segments 6 that are hinged together can be bent easily under the pull of the first pull rope 10 and the second pull rope 12. The end 5 can be inserted into the dialysis tube more easily.

[0026] One side of the end 5 is connected to a first pulling rope 10, and the other side of the end 5 is connected to a second pulling rope 12. Limiting rings 13 are provided on both sides of the chain segment tube 6. The first pulling rope 10 and the second pulling rope 12 pass through the limiting rings 13 on both sides respectively. The hollow handle 1 has a traction assembly inside for pulling the second pulling rope 12 and the first pulling rope 10 respectively. The traction assembly includes a convex slider 11. An adjusting groove 3 is provided on one side of the upper end of the hollow handle 1. The upper end of the convex slider 11 is slidably connected to the adjusting groove 3. An adjusting slider 2 is fixedly connected to one end of the adjusting groove 3 that protrudes from the hollow handle 1. The first pulling rope 10 and the second pulling rope 12 are respectively connected to the two ends of the convex slider 11. The interior of the hollow handle 1 is far from... One end of the hollow guide rod 4 is also provided with a guide wheel 17 for guiding the second traction rope 12; the upper end face of the control slider 2 is provided with an arc-shaped finger groove; in use, the sliding control slider 2 can drive the convex slider 11 to move, and the movement of the convex slider 11 can pull the first traction rope 10 or the second traction rope 12. When the convex slider 11 slides towards the hollow guide rod 4, the second traction rope 12 is pulled, while one side of the first traction rope 10 is relaxed. At this time, the chain segment tube 6 bends towards the side of the second traction rope 12. When the convex slider 11 moves in the opposite direction to the hollow guide rod 4, the first traction rope 10 is pulled, while the second traction rope 12 on the other side is relaxed. At this time, the chain segment tube 6 bends towards the side of the first traction rope 10, thereby realizing flexible control of the chain segment tube 6.

[0027] The hollow handle 1 has a locking component on one side for locking the position of the convex slider 11. The locking component includes a side slide groove 8 and a hollow sleeve 15. The side slide groove 8 is located on one side of the hollow handle 1. A threaded rod 9 is fixedly connected to the side of the convex slider 11 near the side slide groove 8. A threaded sleeve 16 is fixedly connected to one end of the hollow sleeve 15. One end of the threaded rod 9, which extends out of the side slide groove 8, is threadedly connected to the threaded sleeve 16. A handle 7 is fixedly connected to the end of the hollow sleeve 15 away from the threaded rod 9. Several grooves are formed on the circumferential surface of the handle 7. When it is necessary to lock the position of the convex slider 11, the handle 7 can be rotated to rotate the hollow sleeve 15. Through the cooperation of the threaded sleeve 16 and the threaded rod 9, the end of the hollow sleeve 15 can be pressed against the hollow handle 1, thereby fixing the position of the convex slider 11.

[0028] The surface of the hollow handle 1 is covered with a rubber anti-slip sleeve, and the surface of the anti-slip sleeve is provided with anti-slip patterns; the anti-slip sleeve and anti-slip patterns can improve the comfort of gripping and effectively play an anti-slip role.

[0029] The working principle of this utility model is as follows: When in use, hold the hollow handle 1 and insert the end 5, chain segment tube 6 and hollow guide rod 4 into the dialysis tube. Then, control the insertion depth through the hollow handle 1, and at the same time, control the bending of the chain segment tube 6 through the sliding adjustment slider 2 to reset the dialysis tube.
