Abstract: The present invention provides a method and apparatus for monitoring an infusion pump. The method and apparatus provides an encoder which is used with a motor of the infusion pump and a monitoring method which effectively provides rotational directional information. The present 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: 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: An automatic tube loading apparatus, for use with an infusion pump, comprises cams (614,624 fig 19) to actuate pawls 514 mounted on layshaft 512 which are operable to draw tube 5 towards a tubestop on platen 500 via tube capture surface 528. The cams are driven by a motor (550 fig 20) having an encoder (702,704,705 fig 20) so that the position of the cams may be deduced. If the tube is outside the loading area, tube reject surface 532 will expel the tube 5. The pawls are driven by sprung cam followers so if the tube 5 is partially loaded, misload activating surface 530 will pinch the tube 5. An electronic circuit detects from a sensor that the pawl has then stopped, but that the cams are still moving, such differential movement causing the motor to reverse direction to open the pawls and expel the tube 5.

Abstract: In a medical infusion pump an assembly (Figs 18,19) is operative to automatically load or unload a tube 8 or an IV set into or out of a pumping assembly (Fig 2). Associated with the assembly for automatically loading or unloading the tube is an assembly for opening or closing a slide clamp (895, Fig 27). When the loading of the tube is initiated a number of pawls (514, Figs 16,18) and an upper jaw clasp the tube and draw it into a tubeway where it is held. The pumping assembly achieves a wholly mechanical synchronisation of the tube deformation/reformation and the operation of valves (412,414, Figs 13,14) associated therewith to produce a mechanical linearisation of output per pumping cycle. The occlusion of the tube in synchronism with operation of the valves is such that free-flow of medicament never occurs. Also disclosed are sensors for measuring various quantities associated with fluid flowing through the tube.
