摘要： A flow control valve for medical liquid is disclosed. The valve has a housing including an inlet, an outlet, and a flow path therebetween. A plurality of flow restrictors are located in the flow path to define a plurality of flow streams of differing flow rates. A flow control member is disposed in the flow path, and has a plurality of discrete apertures in a first region or plane and at least one aperture in a second region or plane spaced apart from the first plane. The flow control member is rotationally movable and defines an annular gap and radial groove which provide fluid communication between the different planes and the outlet regardless of the orientation of the flow control member. The flow control member may be rotated between a first position in which one of the plurality of apertures in the first plane is in communication with one of the flow streams to define a first flow rate through the valve, and a second position in which one of the at least one aperture in the second plane is in communication with a different one of the flow streams to define a second flow rate through the valve different from the first flow rate.

摘要： A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.

摘要： A vacuum demand value (10) is capable of delivering a flowable material. The valve (10) has a housing (11) having a proximal end (14), a distal end (16), an intermediate segment (18) therebetween defining a passageway (24) wherein the flowable substance can flow from the proximal end (14) to the distal end (16). The housing (11) can be tubing. A valve member (20) is located along the intermediate segment (18). The valve member (20) has a closed condition wherein the flowable material from the proximal end (14) to the distal end (16) is stopped and an open condition wherein the flow of the flowable material from the proximal end (14) to the distal end (16) is unstopped. The valve member (20) is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway (24) for placing the valve member (20) in the open condition.

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.
