PROBLEM TO BE SOLVED: To provide a combined pump unit for a dialysis machine with a common console panel to which a blood pump and a syringe pump are detachably attache. SOLUTION: The combined pump unit comprises the console panel made of a synthetic resin, a combined pump unit base 5 which is fixed on the surface of the panel, has a rotor housing 3 for the blood pump and a syringe base 4 for the syringe pump, and is made of a synthetic resin, a main body 6 of the blood pump attached to and detached from the rotor housing for the blood pump, a main body 7 of the syringe pump attached to and detached from the syringe base, a blood pump motor and a syringe pump motor which are attached to and detached from the reverse side of the combined pump unit base, and sensors and a drive circuit board for detecting the state of each pump. The syringe base includes a syringe pressing guide, a support part for a pusher feeding mechanism, and a support part for a syringe external cylinder, and the drive circuit substrate includes a motor driver and signal processing circuits for the sensors.
