Patent number: 11786718Abstract: 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.Type: GrantFiled: January 6, 2023Date of Patent: October 17, 2023Assignee: ECP ENTWICKLUNGSGESELLSCHAFT MBHInventor: Reiner Liebing
