Feeding set with cassette and related methods therefor

摘要

A pump set for use with a pumping apparatus having a rotor with a plurality of rollers mounted on the rotor rotatable about an axis of rotation is disclosed. The pump set comprises a cassette body comprising a stator member with a fixed portion secured to the cassette body, a second portion opposite the fixed portion, a reaction surface and a second surface opposite the reaction surface, the reaction surface defined between the fixed portion and the second portion, and a tube secured to the cassette body, at least a portion of the tube is disposed against the reaction surface.

1. A pump set for use with a pumping apparatus having a pumping system including a rotor for rotation about a pump axis and at least one roller mounted on the rotor for engaging a pump set, the pump set comprising:
a resiliently deformable tube for carrying a liquid; and a cassette receiving the resiliently deformable tube and adapted for releasable attachment to the pumping apparatus to mount the pump set on the pumping apparatus for engagement by the at least one roller to deliver fluid through the pump set, the cassette comprising a flexible stator having a stator surface arranged to be in generally opposed relation to said at least one roller to act as a reaction surface against which the resiliently deformable tube is squeezed by the rotor, the flexible stator member being at least partially free to float in a stator opening when the resiliently deformable tube is engaged by the at least one roller, the flexible stator member having a transverse rib extending transverse to a length of the flexible stator member, the transverse rib being disposed on a bottom surface of the flexible stator member opposite the stator surface, wherein the transverse rib comprises a first transverse rib, the flexible stator member further comprising a second transverse rib extending transverse to the length of the flexible stator member, the second transverse rib being disposed on the bottom surface of the flexible stator member.
