Abstract: We provide an ostomy collection device including: a housing defining a collecting volume for receiving and storing waste from an ostomy appliance, the housing including an inlet for fluidly connecting to an outlet of an ostomy appliance so that waste from the ostomy appliance flows into the collecting volume; and a cover layer positioned over an external surface of the housing.

Abstract: An I.V. pump cassette includes an enclosed pumping chamber with an inlet and outlet adapted to be connected to I.V. tubing. A reciprocable plunger extends from the top of the pumping chamber. The cassette is arranged to be received in a semi-cylindrical chamber in a driver mechanism wherein a horizontally extending support portion of the cassette can be supported in a semi-circular recess and clamped thereon by overlying clamp members of the driver mechanism. An upstanding semi-circular fence is provided at the front end of the cassette to activate a laterally pivotable switch in the appropriate driver mechanism and to create an interference with the wall of the semi-cylindrical chamber in an inappropriate driver mechanism.
