Description

technical field [0001] The invention relates to the field of dialyzers, in particular to a needle assembly device for producing puncture needles. Background technique [0002] Dialyzer, commonly known as artificial kidney, has been widely used clinically. By performing hemodialysis, the patient's life can be appropriately extended. A dialyzer usually includes a housing, a hollow fiber arranged in the housing, a blood inlet pipe, a blood outlet pipe, a dialysate outlet pipe and a dialysate inlet pipe arranged at both ends of the housing. During hemodialysis, blood flows into each hollow fiber from the blood inlet tube, and after being filtered by the hollow fiber tube, flows back to the blood vessel of the patient from the blood outlet tube, and at the same time, the dialysate enters the shell through the dialysate inlet tube outside the hollow fiber The flow direction of the dialysate is opposite to that of the blood flow. Under the action of the osmotic pressure and the p...
