Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and in particular relates to a stent for a kidney dialysis tube. Background Technology

[0002] For routine arteriovenous fistula puncture, the arm is the puncture site for hemodialysis. The position of blood vessels in the arm is fixed, resulting in a high success rate of puncture and reducing dialysis preparation time.

[0003] After a dialysis puncture in the arm, medical staff use medical tape to secure the dialysis catheter. However, the catheter is easily pulled during arm movement, leading to catheter displacement and bleeding at the puncture site. Furthermore, the catheter can be compressed unnecessarily, potentially causing blood flow obstruction and thrombosis. To address these shortcomings, we propose a dialysis catheter stent for kidney disease. Utility Model Content

[0021] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a kidney dialysis catheter stent of this utility model.

[0022] like Figure 1-7 As shown, the present invention provides a dialysis catheter stent for kidney disease, comprising: an arm support frame, a protective structure, and a dialysis catheter fixing structure.

[0023] The arm support frame consists of an arm support pad 10 and detachable pad blocks. The detachable pad blocks are installed on the lower surface of the arm support pad 10 by snap-fit. The detachable pad blocks include a left pad block 11 and a right pad block 12. The lower surface of the arm support pad 10 has two slots 13 symmetrically opened, corresponding to the left pad block 11 and the right pad block 12. The left pad block 11 and the right pad block 12 are in an interference fit with the slots 13. The arm support pad 10, the left pad block 11 and the right pad block 12 are all filled with memory foam. The bottom surface of the left pad block 11 and the right pad block 12 is an arc-shaped curved surface. After the left pad block 11 and the right pad block 12 are installed, the arm support pad 10 forms a 30° tilt angle with the horizontal plane. The interference fit can prevent the detachable pad blocks from loosening after they are fixed.

[0024] Before puncture, the left pad 11 and right pad 12 are removed from the arm support pad 10, so that the lower surface of the arm support pad 10 directly contacts the bed surface, making the arm support pad 10 parallel to the bed surface, which facilitates the puncture operation. After dialysis, the left pad 11 and right pad 12 are installed, so that the arm support pad 10 forms a 30° support slope with the bed surface, which can raise the patient's arm and accelerate the return of blood and lymph to the heart through gravity, reduce local tissue fluid exudation after dialysis, and reduce the incidence of swelling. By installing or removing the removable pads, the arm support angle (0° or 30°) can be quickly switched, thus adapting to the needs of the puncture period and the postoperative recovery period.

[0025] The protective structure is located above the arm support frame and includes a semi-circular shield 20 and an assembly assembly, which consists of positioning components and restraint components.

[0026] The restraint components include a strap 40, a second hook and loop fastener 41, and a loop fastener 42. The second hook and loop fastener 41 is symmetrically fixed at both ends of the strap 40, and the loop fastener 42 is symmetrically fixed at the front and back of the arm support pad 10, and is adapted to and connected to the first hook and loop fastener 31 and the second hook and loop fastener 41 and the loop fastener 42.

[0027] The positioning components include a positioning pin 50 fixedly installed at the bottom of the semi-circular shield 20 and a positioning groove 51 opened on the upper surface of the arm support pad 10. The positioning pin 50 and the positioning groove 51 are fixed by plugging. After the arm is punctured, the positioning pin 50 at the bottom of the semi-circular shield 20 is inserted into the positioning groove 51 of the arm support pad 10 to complete the initial positioning. Then, the strap 40 is wrapped around the semi-circular shield 20 and is bonded to the hook and loop surfaces 42 on the front and back of the arm support pad 10 through the second hook and loop hook surfaces 41 at both ends to form a stable restraint.

[0028] The dialysis tube fixing structure includes a tube clamp 30 and a first Velcro hook surface 31. The first Velcro hook surface 31 is symmetrically fixed on both sides of the tube clamp 30. The front and back of the arm support pad 10 are provided with through grooves 14 for the dialysis tube to pass through. After puncture, the dialysis tube is led out from the through groove 14, the tube clamp 30 is used to hold the dialysis tube, and the first Velcro hook surface 31 is bonded and fixed to the Velcro loop surface 42 on the side of the arm support pad 10 to achieve double anti-slip and avoid contact with the bed surface.

[0029] After the punctured arm is placed in the arm support pad 10, the semi-circular shield 20 can cover the puncture area to avoid external collisions or pressure on the dialysis tube. The through-type groove 14 can guide the dialysis tube in a directional manner to prevent the tube from twisting or bending. It works in conjunction with the tube clamp 30 and the first Velcro hook surface 31 to fix the dialysis tube with double insurance to prevent pulling and displacement, effectively protecting the dialysis tube and the puncture site.

[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
