DEVICE FOR FEEDING SINGLE-PHASE AND POLYPHASE FLUIDS

摘要

The invention relates to a device for non-alterative propelling of single-phase and polyphase fluids, specially a blood pump, having a rotating member, which feeds energy to the fluid to be propelled, and at least one regulating device, which is placed in front of and/or behind the rotating member. According to the invention, the rotating member is configured as a tube (2), in whose inner side the blading (32) is fixed or forms a single piece, wherein the tube (2) is placed from the outside in the housing (7) of the device (1). The invention provides a device for non-alterative propelling of single-phase polyphase fluids, which does not alter or insignificantly changes the properties of the medium to be propelled and which considerably reduces hemolysis and the formation of thrombus during the propelling of blood.
