1. A blood pump comprising:
a rotor, wherein the rotor is a compressible and expandable rotor;
a pump housing having an interior for accommodating the rotor; and
a valve within the pump housing at an axial distance to the rotor for changing a flow resistance for a fluid flow passing through the interior of the pump housing,
wherein the pump housing comprises:
a housing skin, wherein the housing skin is stretch-resistant, radially compressible and expandable, revolving in a circumferential direction, the housing skin formed of a stretch-resistant material which is configured to stretch less than 5% when the housing skin is fully expanded compared to when the housing skin is in an unstressed state, wherein the housing skin limits expansion of the pump housing;
at least one reinforcement, the at least one reinforcement being configured to expand in the circumferential direction with expansion of the housing skin; and
a ring revolving in the circumferential direction of the pump housing and surrounding the at least one reinforcement at least in sections, and
wherein the valve comprises at least one baffle that is pivotable, elastically deformable, or pivotable and elastically deformable.
