PROBLEM TO BE SOLVED: To provide a hemodialysis apparatus in which an undiluted solution A for dialysis and an undiluted solution B for dialysis are prevented from being mixed almost as the undiluted solution when cleaned, and the corrosion of a metallic portion can be prevented.SOLUTION: A hemodialysis apparatus 2 includes: an undiluted solution A passage 24 for supplying an undiluted solution A for dialysis containing a sodium chloride as the main component and containing calcium in a mixing vessel; and an undiluted solution B passage 25 for supplying an undiluted solution B for dialysis containing a sodium hydrogen carbonate as the main component in the mixing vessel. Undiluted solution A supply piping 7 and undiluted solution B supply piping 8 can be connected to the undiluted solution A passage 24 and the undiluted solution B passage 25, respectively. A bypass passage 41 is provided for bringing the undiluted solution A passage 24 into communication with a waste liquid passage 28. When the undiluted solution A passage 24 and the undiluted solution B passage 25 are cleaned, the cleaning solution supplied from the undiluted solution A supply piping 7 is discharged out of the waste liquid passage 28 through the bypass passage 41 from the undiluted solution A passage 24. Accordingly, the undiluted solution A for dialysis and the undiluted solution B for dialysis can be prevented from being mixed almost as the undiluted solution. |
