Abstract
An apparatus comprising a housing, a curved wall surface on the housing and a tube compressor carried by the housing. A compressible tube, which defines at least a portion of the passage, is positioned between the curved wall surface and the tube compressor. The tube compressor is mounted on the housing for free radial movement relative to the curved wall surface and for rotational movement. The tube compressor can be releasably drivingly coupled to an external rotary input so that the tube compressor can be rolled along the tube to pump fluid in the tube.
