The invention relates to a fluid pump having a housing delimiting a fluid chamber and having a conveying element for the fluid disposed in the fluid chamber, the housing, with respect to the shape and/or size thereof, being able to be changed between at least a first, expanded state and a second, compressed state. The object, to stabilize adequately a corresponding housing, is achieved according to the invention by the housing having at least one stabilization chamber which can be supplied with a fluid pressure and is different from the fluid chamber, the first state of the housing being assigned to a first fluid pressure in the stabilization chamber and the second state of the housing being assigned to a second fluid pressure.
