1. An elastomeric membrane for a medical elastomer pump for conveying a medical fluid, wherein the elastomeric membrane forms a pump volume for receiving and conveying the medical fluid and is elastically stretched in a filled state of the pump volume at least partially filled with the medical fluid, as a result of which the elastically stretched elastomeric membrane exerts a conveying pressure on the pump volume so as to convey the medical fluid, the elastomeric membrane having a plurality of bulge portions that, at least in a filled state, curve outward so as to each form a respective bulge, the respective bulges each forming a pump volume portion of the pump volume.
