Internal fistula arm fixing device capable of inducing bleeding

Technical Field

The utility model relates to the field of medical equipment, concretely relates to internal fistula arm fixing device that can respond to hemorrhage.

Background

Hemodialysis is one of the kidney replacement treatment modes of acute and chronic renal failure patients, and is used for draining blood in vivo to the outside, performing substance exchange in a dialyzer consisting of hollow fibers through dispersion convection, removing metabolic wastes in vivo, maintaining the balance of electrolytes and acid and alkali, and simultaneously removing excessive water in vivo. The establishment and maintenance of a good vascular access are the primary conditions for ensuring smooth blood purification and adequate dialysis. The vascular access is also a 'life line' for maintaining hemodialysis patients for a long time, and the ideal vascular access has enough blood flow during hemodialysis, is convenient to puncture, is durable, and has few complications.
