Protective stent device for hemodialysis puncture part

Abstract

The invention discloses a protective stent device for a hemodialysis puncture part, relates to the technical field of hemodialysis, and particularly relates to a protective stent device for a hemodialysis puncture part. The protective stent device comprises a base, wherein the side surface of the base is fixedly connected with a fixing frame; one end of the fixing frame is provided with a spacing hole, and one end of the fixing frame is sleeved with a threaded rod in a threaded mode; and one end of the threaded rod extends to the top of the fixing frame and is connected with a pressing plate in a clamped mode. According to the protective stent device for the hemodialysis puncture part, a supersaturated sodium acetate solution inside a water bag is quickly heated by starting a heating wire when an arm is put on the surface of the water bag for puncture hemodialysis due to the matched arrangement of the water bag and the heating wire, so that the arm of the patient can be warmed, the problem that the patient feels cold since the arm is put outside during hemodialysis can be avoided, and the patient feels comfortable when putting the arm on the surface of the water bag due to the supersaturated sodium acetate solution inside the water bag.

Description

technical field [0001] The invention relates to the technical field of hemodialysis, in particular to a protective bracket device for hemodialysis puncture sites. Background technique [0002] Hemodialysis is one of the renal replacement therapy methods for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. Inside and outside the hollow fiber, materials are exchanged through the principles of dispersion, ultrafiltration, adsorption and convection to remove metabolic waste in the body, maintain electrolyte and acid-base balance, and remove excess water in the body at the same time, and return the purified blood to the whole body. The procedure is called hemodialysis. During hemodialysis, it is necessary to puncture the patient's arm to extract and reinfuse the blood.

AI Technical Summary

Problems solved by technology

During hemodialysis, it is necessary to puncture the patient's arm to extract and reinfuse the blood. One dialysis takes a long time, and it is not convenient to expose the puncture site for a long time. In order to prevent the patient or other personnel from colliding with the puncture during the dialysis process The site causes blood oozing at the puncture site and needle slippage. At the same time, the patient's arm needs to be placed outside for a long time during hemodialysis, which will cause the patient to feel cold during dialysis. Therefore, we propose a method for hemodialysis puncture Parts of the protective bracket device
