    • A dialysis device 1 includes a water supply passage 15 for supplying clean water to solution supply chambers 35a and 35b, and a waste solution passage for discharging a used dialysis solution from solution collection chambers 34a and 34b, and the water supply passage includes a concentrate solution pump 21 that supplies a dialysis concentrate solution from concentrate solution supply source 19. The concentrate solution pump is a piston pump 40 that moves a piston 42 up and down in a cylinder 41 to feed a solution, the piston pump is provided in the way of washing passage 26 provided between the water supply passage and the waste solution passage, and an open/close valve 27 that intermittently opens and closes is provided in the washing passage to flow the clean water in the water supply passage through a gap between the cylinder and the piston.
    • 透析装置1包括用于向溶液供给室35a和35b供给清洁水的供水通道15和用于从溶液收集室34a和34b排出所使用的透析溶液的废液通道,以及供水通道 包括从浓缩液供给源19供给透析浓缩液的浓缩液泵21.浓缩液泵是将活塞42在气缸41中上下移动以供给溶液的活塞泵40,提供活塞泵 在供水通道和废液通道之间设置的洗涤通道26的方式和间歇地打开和关闭的打开/关闭阀27设置在洗涤通道中以使供水通道中的清洁水通过间隙 在气缸和活塞之间。
