Abstract:
Provided is a blood purification device which makes it possible for a B agent stock solution used in a blood purification treatment process to be used as an alkali agent in a fat removal washing process, and which makes it possible to remove carbon dioxide produced during the fat removal washing process and favorably perform the fat removal washing. The blood purification device comprises: a tube section having a dialysis fluid feed line L1 and a drainage fluid drainage line L2; a duplex pump 1; and a control unit 13 for performing a blood purification treatment process in which an A agent stock solution and a B agent stock solution are introduced into the tube section and mixed, and then diluted to a prescribed concentration to produce a dialysis fluid that is supplied to a dialyzer C to perform a blood purification treatment, and a fat removal washing process in which an aqueous sodium carbonate solution obtained by supplying the B agent stock solution into the tube section and heating the B agent stock solution is circulated to remove fat in the tube section, so as to perform fat removal washing. While preforming the fat removal washing process, the control unit 13 drains, to the outside of the tube section, carbon dioxide that is generated when circulating the aqueous sodium carbonate solution.
