Description

Technical Field

[0001] This utility model relates to the field of fixation device technology, specifically to an adjustable fixation device for dialysis tubing used in nephrology. Background Technology

[0002] In dialysis treatment in nephrology, proper fixation of the dialysis catheter is crucial for the smooth progress of treatment and patient safety. Traditional dialysis catheter fixation methods often have many shortcomings. Ordinary clamps lack flexibility, are difficult to adapt to dialysis catheters of different diameters, and the clamping force is difficult to control. Too tight a clamp may damage the dialysis catheter, affecting its lifespan and fluid delivery performance, while too loose a clamp may not provide effective fixation and also pose a risk of catheter displacement. In summary, to solve the above problems, adapt to dialysis catheters of different sizes, and reduce risks, this utility model has been developed. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an adjustable fixing device for dialysis catheters in nephrology, comprising: a binding strap; a rotating structure, the bottom of which is fixedly connected to the top of the binding strap; a clamping structure, the bottom of which is fixedly connected to the top of the rotating structure; and a protective structure, the bottom of which is fixedly connected to the top of the clamping structure. The clamping structure includes a support frame, the bottom of which is fixedly connected to the top of the rotating structure. A rotary motor is fixedly connected to the outer wall of the support frame, a rotating rod is fixedly connected to the output shaft of the rotary motor, a connecting rod is rotatably connected to the outer wall of the rotating rod, and a clamping rod is rotatably connected to the outer wall of the connecting rod.

[0004] Preferably, the protective structure includes a connecting block, a protective block is fixedly connected to the outer wall of the connecting block, and a rubber gasket is fixedly connected to the outer wall of the protective block.

[0005] Preferably, the bottom of the connecting block is fixedly connected to the top of the clamping rod, and the outer wall of the clamping rod is slidably connected to the inner wall of the support frame. The clamping structure uses a rotary motor to drive the rotating rod and the connecting rod to control the opening and closing degree of the clamping rod, which can adapt to dialysis tubes of various diameters. The protective block and rubber gasket in the protective structure provide dual protection for the dialysis tube.

[0006] Preferably, the rotating structure includes a rotating plate and a stabilizing rod, the outer wall of the rotating plate is rotatably connected to the outer wall of the binding strap, and the outer wall of the rotating plate is provided with a stabilizing groove.

[0007] Preferably, a stabilizing block is rotatably connected to the outer wall of the stabilizing rod, and a stabilizing spring is fixedly connected to the outer wall of the stabilizing block.

[0008] Preferably, the stabilizing groove matches the stabilizing block, and the end of the stabilizing spring away from the stabilizing block is fixedly connected to the top of the binding strap. The design of the rotating structure allows the device to flexibly adjust the angle. During operation, simply pressing the stabilizing block is sufficient to adjust the rotation of the rotating plate. After adjusting to the appropriate angle, it can be quickly fixed again.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model features a clamping structure that utilizes a rotary motor to drive a rotating rod and a connecting rod, controlling the opening and closing of the clamping rod. This allows it to accommodate dialysis tubing of various diameters. The protective block and rubber gasket in the protective structure provide dual protection for the dialysis tubing. On one hand, it prevents the clamping rod from directly contacting the dialysis tubing, thus preventing pinching or wear. On the other hand, the rubber gasket increases the friction between the dialysis tubing and the clamping rod, making the dialysis tubing more stable after being clamped.

[0011] 2. This utility model features a rotating structure that allows for flexible angle adjustment. During operation, simply pressing the stabilizing block adjusts the rotation of the plate, and the plate can be quickly fixed back into place once the desired angle is reached. This facilitates positioning by medical staff based on the patient's position and the location of the dialysis equipment, ensuring the dialysis tubing is in optimal connection and working condition. This effectively reduces problems such as poor fluid delivery or tubing damage caused by dialysis tubing twisting or bending. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0018] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an adjustable fixing device for dialysis catheters used in nephrology, comprising: a binding strap 1; a rotating structure 4, the bottom of which is fixedly connected to the top of the binding strap 1; a clamping structure 2, the bottom of which is fixedly connected to the top of the rotating structure 4; a protective structure 3, the bottom of which is fixedly connected to the top of the clamping structure 2; the clamping structure 2 includes a support frame 21, the bottom of which is fixedly connected to the top of the rotating structure 4, a rotating motor 22 fixedly connected to the outer wall of the support frame 21, and a rotating rod 23 fixedly connected to the output shaft of the rotating motor 22. A connecting rod 24 is rotatably connected to the outer wall of rod 23, and a clamping rod 25 is rotatably connected to the outer wall of connecting rod 24. In use, the clamping structure 2 relies on the support frame 21 as the main frame. The rotary motor 22 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the connecting rod 24 to move. Since the connecting rod 24 and the clamping rod 25 are rotatably connected, as the rotating rod 23 rotates, the clamping rod 25 will slide on the inner wall of the support frame 21 and change its relative position to achieve the clamping action of the dialysis tube. By controlling the forward and reverse rotation and rotation angle of the rotary motor 22, the opening and closing degree of the clamping rod 25 can be adjusted to adapt to dialysis tubes of different diameters.

[0019] The protective structure 3 includes a connecting block 31, a protective block 32 is fixedly connected to the outer wall of the connecting block 31, and a rubber gasket 33 is fixedly connected to the outer wall of the protective block 32.

[0020] The bottom of the connecting block 31 is fixedly connected to the top of the clamping rod 25, and the outer wall of the clamping rod 25 is slidably connected to the inner wall of the support frame 21. In use, the connecting block 31 of the protective structure 3 is fixed to the top of the clamping rod 25. The protective block 32 and the rubber gasket 33 protect the clamped dialysis tube and prevent the dialysis tube from being pinched or worn. The rubber gasket 33 can also increase the friction between the dialysis tube and the dialysis tube, further stabilizing the fixed position of the dialysis tube.

[0021] The rotating structure 4 includes a rotating plate 41 and a stabilizing rod 44. The outer wall of the rotating plate 41 is rotatably connected to the outer wall of the binding strap 1, and a stabilizing groove 42 is provided on the outer wall of the rotating plate 41.

[0022] A stabilizing block 43 is rotatably connected to the outer wall of the stabilizing bar 44, and a stabilizing spring 45 is fixedly connected to the outer wall of the stabilizing block 43.

[0023] The stabilizing groove 42 matches the stabilizing block 43. The end of the stabilizing spring 45 away from the stabilizing block 43 is fixedly connected to the top of the binding strap 1. In use, the binding strap 1 is first used to fix the entire device to a suitable part of the patient's body, providing a stable base support for the device. The rotating plate 41 in the rotating structure 4 can be rotated and adjusted through the cooperation of the stabilizing rod 44 and the stabilizing block 43. The stabilizing block 43 is located in the stabilizing groove 42 of the rotating plate 41 and is connected to the stabilizing spring 45. When it is necessary to adjust the angle, press the side of the stabilizing block 43 close to the stabilizing spring 45 to make the stabilizing block 43 disengage from the stabilizing groove 42. Then rotate the rotating plate 41. After rotating the rotating plate 41 to a suitable angle, release the stabilizing block 43. Under the action of the stabilizing spring 45, the stabilizing block 43 rotates around the stabilizing rod 44, so that the stabilizing block 43 is once again locked inside the stabilizing groove 42, thereby fixing the rotating plate 41 again.

[0024] Working principle:

[0025] In use, the first step is to use the strap 1 to fix the entire device to a suitable part of the patient's body, providing a stable base support for the device. The rotating plate 41 in the rotating structure 4 can be rotated and adjusted through the cooperation of the stabilizing rod 44 and the stabilizing block 43. The stabilizing block 43 is located in the stabilizing groove 42 of the rotating plate 41 and is connected to the stabilizing spring 45. When it is necessary to adjust the angle, press the side of the stabilizing block 43 close to the stabilizing spring 45 to make the stabilizing block 43 disengage from the stabilizing groove 42. Then rotate the rotating plate 41 to a suitable angle, and then release the stabilizing block 43. Under the action of the stabilizing spring 45, the stabilizing block 43 rotates around the stabilizing rod 44, so that the stabilizing block 43 is once again engaged in the stabilizing groove 42, thereby fixing the rotating plate 41 again.

[0026] In use, the clamping structure 2 relies on the support frame 21 as the main frame. The rotary motor 22 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the connecting rod 24 to move. Since the connecting rod 24 is rotatably connected to the clamping rod 25, as the rotating rod 23 rotates, the clamping rod 25 will slide on the inner wall of the support frame 21 and change its relative position to achieve the clamping action of the dialysis tube. By controlling the forward and reverse rotation and the rotation angle of the rotary motor 22, the opening and closing degree of the clamping rod 25 can be adjusted to adapt to dialysis tubes of different diameters.

[0027] When in use, the connecting block 31 of the protective structure 3 is fixed to the top of the clamping rod 25. The protective block 32 and the rubber pad 33 protect the clamped dialysis tube, preventing it from being pinched or worn. The rubber pad 33 can also increase the friction between the dialysis tube and the dialysis tube, further stabilizing the fixed position of the dialysis tube.

[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
