ABSTRACT:
A disposable reservoir cassette for use with a roller pump delivery system comprises a flexible reservoir tube, an air-permeable, liquid-impermeable element engaging one end of the reservoir tube, a pierceable delivery septum engaging the other end of the reservoir tube and a rigid housing containing the reservoir tube. The housing includes a backstop which supports the tube in a circular path while allowing access to the septum. The housing is adapted to be secured to the roller pump such that the circular path of the tube is adjacent to the path of a pump roller wherein motion of the pump roller compresses the reservoir tube sufficiently to drive any fluid contained therein in the direction of the delivery septum.
