Abstract

The present invention disclosed a blood purification device that can simplify the structure of the device; it can be easily and smoothly performed by hemodialysis (HD), blood filtration therapy (HF), and hemodialysis filtration therapy (HDF); and beforeDilute, post -dilution and the choice of dilution before and after.The blood purification device contains the valve component that can be arbitrarily closed and opens the dialysis solution to guide the circulation and the supply line of the dialysis solution; by the operation of the valve component, it can selectively open the dialysis solution to guide the circulation, the supply of dialysis solution supply while turbines the supply of dialysis solutionThe hemodialysis therapy of the line, the edge shutdown dialysis solution is performed, and the blood filtration therapy of the supply line supply the thread is opened, and the exterior shutdown and open dialysis solution supply line and the dialysis solution supply line can be performed at the same time.Control department of hemodialysis filtration therapy.

Description

technical field [0001] The invention relates to a blood purification device for purifying a patient's blood while undergoing extracorporeal circulation. Background technique [0002] In general, a blood purification device for dialysis treatment includes: an arterial side blood circuit and a venous side blood circuit constituting a blood circuit for extracorporeal circulation of patient's blood; A blood purifier; and a device body equipped with various treatment components such as a blood pump for blood purification treatment in the blood circuit and the blood purifier. Arterial-side puncture needles and venous-side puncture needles can be assembled at the front ends of the arterial-side blood circuit and the venous-side blood circuit, respectively. [0003] Next, after puncturing the patient with the arterial side puncture needle and the venous side puncture needle, by driving the blood pump, the patient's blood will flow in the arterial side blood circuit and the venous s...
