A medical fluid pump, comprising a first, inner fluid system including a motor-driven suction/pressure unit and a first fluid pressure chamber which can be filled with fluid and emptied by the suction/pressure unit, and a second, outer fluid system including a second fluid pressure chamber which is coupled to the first pressure chamber in a pressure- and/or volume-dynamic manner via a movable separating wall and which is alternately coupled&#x2014;via a valve means of the second fluid system&#x2014;to a suction line and pressure line depending on the current working phase of the suction/pressure unit of the first fluid system is disclosed.

Pump for medical purposes

The syringe pump comprises a receiving position for a syringe. The piston plate of the syringe is moved by a drive head which is fastened to a drive rod. For locking the piston rod prior to fixing the piston plate in the drive head, a braking element is provided on a syringe holding head. The syringe holding head further serves for determining the respective syringe size. After placing the syringe holding head against a syringe cylinder, the brake element is actuated to temporarily engage the piston rod and fix it relatively to the syringe cylinder.
