Description

technical field [0001] The invention relates to the technical field of hemodialysis, in particular to a blood sample collection device for hemodialysis department. 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; at the same time remove excess water in the body, and return the purified blood to the whole body The procedure is called hemodialysis. [0003] During the hemodialysis process, blood samples need to be collected from patients. Most of the existing blood sample collection methods are to use rubber bands to tighten the patient'...
