Description

Technical field:

[0001] The utility model relates to the technical field of calcium carbide furnace equipment, in particular to a forearm fistula protection device based on hemodialysis. Background technology:

[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 electrolyte solutions with similar concentrations to the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, and remove excess water from the body. The whole process of returning the purified blood is called hemodialysis. During hemodialysis, a puncture needle is inserted into the arm and a blanket cannot be covered, resulting in the arm being exposed for a long time, which is easy to get cold and cause blood vessels to contract due to cold stimulation, affecting blood flow. For this reason, patients need to wear a forearm fistula belt for warmth. The general structure of the existing fistula belt includes a strap, which is fixed to the forearm by Velcro, and a graphene heating sheet is set on the inside of the strap to improve the warmth effect. This structure of the fistula belt is difficult for patients to wear alone, and the tightness is not easy to adjust. When the Velcro is torn, the fistula position is affected, causing pain and discomfort to the patient, and the patient has a poor user experience. Utility model content:

[0008] Furthermore, the protective tube and the inflatable liner, and the protective cover and the protective tube are connected via Velcro.

[0009] Furthermore, the protective tube is formed by buckling two shells with semicircular cross sections.

[0010] Furthermore, a pin is connected to one of the shells, and a pin hole is opened on the other shell, and the pin is inserted into the pin hole.

[0011] Furthermore, the pin is made of stainless steel, and a magnet sheet is installed at the bottom of the pin hole.

[0012] The beneficial effects of the utility model: the utility model has a simple structure, and the airbag structure is designed to enable the patient to wear it alone. The tightness of wearing is easy to adjust, the wearing process is quick and convenient, and no secondary damage such as pulling on the fistula position is caused. The comfort level is high, and a graphene heating sheet is installed on the inner wall of the airbag, which has a good warming effect and is worthy of large-scale promotion and use.
