Combined protection device for hemodialysis

Abstract

The invention relates to the technical field of medical instruments, in particular to a combined protection device for hemodialysis, which comprises a protection assembly for protecting a dialysis part, a storable fixing assembly is arranged at the bottom of the protection assembly and is used for fixing the whole device on a bed edge, and a heating assembly is arranged on the inner surface of the protection assembly, so that dialysis site is at constant temperature. The upper protective cover and the lower protective cover which are hinged to each other are arranged, an elliptical hole is formed by the upper protective cover and the lower protective cover in cooperation with a locking structure, and the dialysis part of the arm of the patient can be conveniently placed in the elliptical hole, so that a protective layer is formed, and injuries caused by mistaken touch are reduced; meanwhile, a constant-temperature system composed of a heating pad, a temperature sensor and a temperature controller is arranged on the inner face of the protection assembly, so that the temperature around the arms of the patient is always in a constant-temperature state, and the exposed arms are prevented from being subjected to cold stimulation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined protection device for hemodialysis. Background technique [0002] Hemodialysis, referred to as hemodialysis, also known as artificial kidney and kidney dialysis in popular terms, is a kind of blood purification technology. Excessive electrolytes are removed from the body to achieve the purpose of purifying the blood and correcting the water-electrolyte and acid-base balance. [0003] Hemodialysis therapy is to introduce the patient's blood and dialysate into the dialyzer at the same time (the flow direction of the two is opposite), and use the semipermeable membrane of the dialyzer (artificial kidney) to remove excess toxins and excess water accumulated in the blood. Take it out of the body, and supplement the base to correct acidosis, adjust electrolyte imbalance, and replace the excretory function of the kidney. [0004] The operation process of hemodialysi...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a combined protective device for hemodialysis, which can effectively solve the problem that the patient's arm is exposed to the air during the whole hemodialysis process, which will cause the patient's arm to feel cold. Numbness affects the treatment effect and the patient's comfort is poor; at the same time, there is no protective device, and the dialysis site may be touched by mistake, which is easy to cause damage to the dialysis process
