Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an arm care device for hemodialysis puncture. Background technique

[0002] Hemodialysis is one of the renal replacement therapies 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. The whole process of exchanging substances with the principle of convection, removing metabolic waste in the body, maintaining electrolyte and acid-base balance; at the same time removing excess water in the body, and returning the purified blood is called hemodialysis.

[0003] Patent Publication No. CN 109602558 A discloses a new type of nursing device for hemodialysis puncture, including a fixing seat, an open-source single-chip microcomputer and an adjusting mechanism are installed on the top of the fixing seat, and an arm support seat is fixed at the end of the...
