Abstract:
1. A wobble pump, comprising: a pump module said pump module comprising a flexibly deformable membrane and a base having a recess, wherein the recess and the membrane form a line-shaped pump channel that is curved at least in sections, and wherein the base comprises a pump channel inlet and a pump channel outlet, wherein the pump channel inlet and the pump channel outlet are connected with the pump channel for supplying and discharging fluid in the pump channel in such a way, that through a periodically rotating deformation of the membrane fluid can be pumped through the pump channel from the pump channel inlet to the pump outlet; a wobble pump base module comprising a wobble pump drive system having a wobble device and a receptacle, wherein the receptacle is configured to enable manual insertion into and removal therefrom of the pump module, which insertion/removal connects or separates, respectively, the pump module to/from the wobble device; wherein the membrane comprises a bulge such that the membrane is cross-sectionally convex in at least one section, the bulge configured to interact with the wobble device for deforming the membrane; and wherein the wobble device comprises a protruding bar for acting onto the bulge of the membrane.
