Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dialysis tube fixing mechanism for nephrology. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing similar concentrations to the body are exchanged through diffusion / convection inside and outside the hollow fibers to remove metabolic wastes, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] At present, during the dialysis process, the dialysis tube needs to be fixed so that the dialysis tube and the body maintain a relatively stable position to prevent the dialysis tube from falling off the blood vessel. After searching by the applicant, it was found that the dialysis tube fixing structure disclosed in the prior art requires two steps in the fixing process. The first step is to fix the fixing mechanism itself on the patient's body, and the second step is to fix the dialysis tube on the fixing mechanism. For example, the patent publication numbers are CN214969960U and CN215608122U. The disadvantage is that the structure is relatively complex and the operation is relatively cumbersome. Based on this, the inventor purposefully provides a dialysis tube fixing mechanism for nephrology with a simple and ingenious structure and convenient operation. Utility Model Content

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A dialysis tube fixing mechanism for nephrology comprises a fixing plate, an outer circumferential surface of which is provided with symmetrically arranged restraining bands 1 and 2, the restraining bands 1 and 2 being connected by Velcro, a front surface of the fixing plate is provided with a protrusion and the protrusion is arranged close to the edge of the fixing plate, a plurality of protrusions are provided and are arranged in an array with equal spacing along the circumferential direction of the fixing plate, an arc-shaped slot is formed between two adjacent protrusions, the slot is larger than half of the arc and smaller than three quarters of the arc, an air cushion matching the slot is provided in the slot, the outer circumferential surface of the air cushion is bonded and fixed to the slot, an air bag is provided on the back of the fixing plate, and the air bag is connected to each air cushion by a connecting pipe.

[0007] As a further optimization or improvement of this solution.

[0008] The airbag is a circular elastic structure and can automatically restore its original shape.

[0009] As a further optimization or improvement of this solution.

[0010] A mounting groove is coaxially formed on the back of the fixing plate. The airbag is arranged in the mounting groove and protrudes out of the mounting groove in an initial state.

[0011] As a further optimization or improvement of this solution.

[0012] A transition plate is rotatably arranged at the central part of the front side of the fixed plate, and an arc-shaped transition groove is opened on the transition plate.

[0013] As a further optimization or improvement of this solution.

[0014] The transition groove is larger than one-half of a circular arc and smaller than three-quarters of a circular arc.

[0015] As a further optimization or improvement of this solution.

[0016] Both ends of the transition groove are arranged as trumpet-shaped arc surfaces.
