Abstract
A medical elastomer pump and an elastomeric membrane for use in infusion therapy. The elastomeric membrane forms a pump volume for receiving and delivering a medical fluid. In a filled state of the pump volume, in which the pump volume is filled at least in part with the medical fluid, the elastomeric membrane is resiliently stretched. The resiliently stretched elastomeric membrane applies a delivery pressure onto the pump volume for delivering the medical fluid. The elastomeric membrane has a plurality of bulge portions which, at least in the filled state, are convex, each forming a bulge. The bulges each form a pump volume portion of the pump volume.
