Variable infusion device for medical purposes

摘要

The invention describes a variably adjustable roller tube for an infusion pump for medical purposes as a disposable unit. In a combination of several adjustable roller tubes in an infusion pump all roller tubes are rolled simultaneously and uniformly at a chosen rolling speed. A controlling sidepiece is squeezed by two metering rollers through an adjustment handle. Due to the constriction or widening of the roller tubes in the rolling region delivery from any number of infusion bottles is possible over any period of time.
