The invention concerns a micropump for the substantially continuous delivery of a mass flow, the micropump having a sleeve axis and an offset axis of rotation. An internal rotor meshes with an external rotor in a sleeve and at least one outlet-side pressure opening in a first end-face termination part. Both rotors have a dimension smaller than 10 mm. The invention further concerns a micromotor of similar construction in which the diameter of the rotors and the casing are below 10 mm. The pump and motor are extremely miniaturized yet still permit a continuous flow with high feed pressure and high output.

Micromotor and micropump

The present invention relates to a device for actively supporting the flow of body fluids, comprising an artificial flow guide system ( ) with an operational area into which a pump ( ) is embedded in such a way that it can transport blood from at least one inlet opening ( ) situated in the guide system to at least one outlet opening ( ) situated in the guide system; a flexible feed hose ( ) connected to the flow guide system; an energy or force transmission line ( ) which is guided through the interior of the flexible feed hose and which, when the device is in the operational state, transmits energy or force substantially continuously to the pump from a drive unit for the extracorporeal generation of this energy or force.

System for actively supporting the flow of body fluids

The invention concerns a micropump for the substantially continuous delivery of a mass flow, the micropump having a sleeve axis and an offset axis of rotation. An internal rotor meshes with an external rotor in a sleeve and at least one outlet-side pressure opening in a first end-face insert part which is inserted into the sleeve of slightly largely diameter, is aligned in the axial direction. The invention further concerns a micromotor of similar construction in which the diameter of the delivery hose corresponds approximately to that of the sleeve casing. The pump and motor are extremely miniaturized yet still permit a continuous flow with high feed pressure and high output.
