主权项

1. A medical fluid delivery cassette, comprising:
a base defining an opening; a membrane attached to the base covering the opening, the membrane together with the base defining a fluid pump chamber, a flow pathway that leads from the fluid pump chamber to an inlet of the cassette, and a flow pathway that leads from the fluid pump chamber to an outlet of the cassette, and a portion of the membrane overlying the fluid pump chamber being moveable relative to the base such that the volume of the fluid pump chamber can be changed by applying a force to the portion of the membrane overlying the fluid pump chamber; an adhesive coating on an outside surface of the portion of the membrane overlying the fluid pump chamber; and a release layer substantially covering and releasably attached to the adhesive coating.
