METHOD FOR REDUCING LIQUID IN CIRCUITS OF BLOOD PURIFICATION DEVICE, BLOOD PURIFICATION DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing liquid in circuits of a blood purification device that even enables discharge of liquid in a replenishment liquid supply circuit and enables automation of liquid discharge while maintaining safety of a patient, without complicating a device configuration.;SOLUTION: A method in the invention includes: a first step of reducing liquid in the dialysate supply circuit 13 by delivering liquid remaining in the dialysate supply circuit 13 into a secondary side 10b of a blood purifier 11 and delivering the liquid in the secondary side 10b to a side of a waste liquid circuit 14; a second step of reducing liquid in a replenishment liquid supply circuit 15 by, while keeping each closing part of a blood collection circuit 20 and the blood returning circuit 21 closed, delivering liquid remaining in the replenishment liquid supply circuit 15 into a blood returning circuit 21, delivering the liquid in the blood returning circuit 21 into a primary side 10a of the blood purifier 11, delivering the liquid in the primary side 10a into the secondary side 10b and delivering the liquid in the secondary side 10b to the side of the waste liquid circuit 14; and a third step of reducing the liquid in the waste liquid circuit 14 by delivering the liquid remaining in the secondary side 10b of the blood purifier 11 and in the waste liquid circuit 14 into a waste liquid part 60.;COPYRIGHT: (C)2014,JPO&INPIT
