PUMP DEVICE FOR A MEDICAL LIQUID, AND MEDICAL TREATMENT DEVICE FOR DELIVERING A LIQUID TO THE HUMAN OR ANIMAL BODY

摘要

At least one section (2,3) of the tubing conveying the fluid has a balloon-shaped elastically compressible section (11,12). The two tubing sections branch off from a shared supply pipe (4) and lead into a shared pipe (5), and each possess a separate compressing agent (13) which has a pressure piece gripping the exterior of the balloon-shaped sections. A control controls the frequency and or amplitude of the compressing movements.
