Abstract: An infusion pump which is operable to pump a fluid through a tube is described. The pump comprises a shuttle having upstream and downstream sides which is operable to cyclically deform and reform the tube, a first valve associated with the upstream side of the shuttle, a second valve associated with the downstream side of the shuttle and a cam having a first face which is operable to actuate the shuttle and a second face which is operable to actuate the first and second valves.

Abstract: The present invention provides a method and apparatus for monitoring an infusion pump (10). The method and apparatus provides an encoder (101) which is used with a motor (65) of the infusion pump (10) and a monitoring method which effectively provides rotational directional information. The present invention utilizes a state transition of a first switch (111) indexed against a constant signal from a second switch (113) corresponding to the center of a flag (117) or sector (119).

Abstract: A drive for an automatic tube loading assembly, comprises cams 614,624 mounted on camshaft 510 which actuate a means for loading a tube into an infusion pump. A motor (550 fig 20) drives camshaft 510 through a reduction gearbox (534 fig 20) and helical gears 564,(562 fig 20) when gear 564 is locked to camshaft 510 by pin 588. To allow manual tube loading, clutch tab 602 is tilted on handwheel 600 causing actuator pin 594 to slide into camshaft 510 against spring 596, moving pin 588 out of engagement with a slot in gear 564, thus allowing free rotation of camshaft 510 without rotation of gear 564.
