Abstract

A pumping device for medical infusion apparatus comprises a flexible and resilient tube 1 passing through chambers 4 wherein the tube can expand (owing to the pressure of the infusion liquid in a bottle 3) when a portion(s) of the tube below these chambers is compressed by a horizontally movable rigid element(s) 5, which may be electro-magnetically operated. The liquid is displaced towards the patient by the sections of the tube in the chambers contracting while the upper element(s) 5 compresses the tube and the lower element(s) is retracted. The chambers may be pressurized by devices 9. <IMAGE>
