摘要： 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). An anti-free flow device (136,138) includes the flexible conduit (132) received between an anvil (182) fixedly attached to the frame (134) and a pincher (132) attached to the frame (134), the pincher (138) being movable between a first position biasing the pincher (138) against the anvil (182) to occlude a lumen (150) of the elastomeric conduit (132) and a second position for eliminating the bias of the pincher (138) against the anvil (182) so as to not occlude the lumen (150) of the elastomeric conduit (132). The elastomeric conduit (132) is made of an elongate elastomeric robe having an inlet valve portion (142) and an outlet valve portion (144) made of a furst material and a chamber portion (140) disposed therebetween, the chamber portion being made of a second material. The first material has a durometer of less than a durometer of the second material. The chamber portion (140), inlet valve portion (142) and the outlet valve portion (144) may have a football-shaped cross-section.
