ABSTRACT:
A pressure infusion device for squeezing out a syringe having an absolute path sensor connected to the movable holder and supplying position data of the position of the syringe rod to a control means. Based on the position data, a motor is controlled so that a desired infusion rate is maintained. The infusion rate may be programmed to vary during an infusion process. Shortly before the empty-state position is reached, an early alarm is released, while, in reaching the empty-state position, the drive is turned off.
