Abstract: A medical infusion pump (10) using a pump chamber cassette (86) has a housing (20,22) defining a pump chamber cassette receptacle (84) and a pump driving mechanism (250) for propelling liquid through the pump chamber cassette. A door (50) holds the pump chamber cassette (86) within the cassette receptacle (84) in an operative position relative to the driving mechanism (250). The cassette includes an elastomeric conduit (132), a frame (134) and clips (146,148) for attaching the elastomeric conduit (132) to the frame (134) for holding the elastomeric conduit (132) in a select position relative to the pump driving mechanism (250) of the infusion pump upon placement of the cassette (86) in an operative position relative to the pump driving mechanism (250).
