Abstract
The invention relates to a fluid pump device, in particular for the medical application, with a compressible pump housing and rotor, as well as with an actuation means which runs in the sleeve and on whose end the fluid pump is arranged. In order to utilize all possibilities of a space-saving arrangement of the respective pump housing of the rotor, which is compressible per se, and as the case may be, a bearing arrangement, the mentioned elements are displaceable to one another in the axial direction compared to an operation position. In particular these elements may be end-configured by way of an axial movement of the drive shaft after the assembly.
Claims17
A fluid pump device changeable in diameter, in particular for medical application, with a pump housing which is changeable in diameter, with a rotor which is changeable in diameter and having at least one delivery element for the fluid, as well as with at least one actuation means which may be moved in a longitudinal direction and at whose distal end the fluid pump and at whose proximal end an actuation device, in particular a pull device, is arranged, wherein the pump housing and the rotor are displaceable relative to one another by way of actuating the actuation means, characterized in that the pump housing and the rotor are displaceable to one another in the longitudinal direction of the actuation means to such an extent, that they may be arranged behind one another in the longitudinal direction or with a mutual overlapping in the longitudinal direction, which is smaller than the overlapping during the operation of the fluid pump.
