Document Type and Number:
WIPO Patent Application WO/2023/226109
Kind Code:
A1
Abstract:
An extracorporeal circulation system of a blood purification apparatus and an automatic pre-washing method thereof. The extracorporeal circulation system of the blood purification apparatus comprises a dialyzer (10) and an extracorporeal circulation pipeline, the dialyzer (10) being divided into a blood chamber (11) and a dialysate chamber (12) by means of a semipermeable membrane. The dialyzer (10) is further provided with a blood chamber upper end connector (11a) and a blood chamber lower end connector (11b) which are in communication with the blood chamber (11), and a dialysate upper end connector (12a) and a dialysate lower end connector (12b) which are in communication with the dialysate chamber (12). The extracorporeal circulation pipeline comprises a vein pipeline and an artery pipeline, one end of the artery pipeline being connected to the blood chamber upper end connector (11a), and one end of the vein pipeline being connected to the blood chamber lower end connector (11b). The present invention can effectively solve the problems existing in the prior art, and simplify the operation steps for preparing dialysis treatment to the maximum extent, so that the probability of mis-operation is reduced, and the operation intensity of medical staffs is also reduced.
