Disposable storage cassette for giving medicine to user

摘要

A disposable deposit cassette or case for use with a roller pump delivery system comprises a flexible deposit tube, an air-permeable and liquid-impermeable element which is applied to one end of the deposit tube, a delivery diaphragm which can be perforated and is applied to the other end of the deposit tube, and a rigid housing which contains the deposit tube. The housing includes a back support which supports the tube in a circular path while it allows access to the diaphragm. The housing is intended to be secured to the roller pump in such a manner that the circular path of the tube is adjacent to the path of a pump roller in which the movement of the pump roller compresses the deposit tube sufficiently to impel any fluid contained therein in the direction of the delivery diaphragm.
