Fluid pumping, valve and heating systems, methods and apparatuses for an automated dialysis machine

摘要

A dialysis system (10, 100) comprising: a hardware unit (110) including a pump (20) operating with a pump head (214) and a heater (16); a disposable unit (160) including a pump receptacle (172) in fluid communication with a fluid heating member (180); the hardware unit (110) and the disposable unit (160) configured such that when mated for operation, the pump head (214) comes into operable alignment with the pump receptacle (172) and the heater (16) comes into operable alignment with the fluid heating member (180); and a controller (30) including at least one memory device (32) and at least one processor (34) configured and arranged to (i) cause the pump (20) to move the pump head (214) towards and away from the pump receptacle (172) for pumping dialysis fluid and (ii) cause the heater (16) to heat the dialysis fluid heating member (180) to a desired temperature based on a voltage input into the system.
