An optical motion sensor is provided for monitoring movement of a mechanical device, particularly such as an infusion pump of the type used for controlled delivery of medication to a patient. The motion sensor includes a disk member mounted upon a selected mechanical output component driven by the infusion pump, such that the disk member undergoes displacement during normal pump operation. The disk member defines a pattern of reflective and substantially nonreflective surface zones which are alternately illuminated by a light source during normal pump operation. A light detector responds to the level of reflection from the disk member to provide an output signal which varies according to disk member displacement. This output signal is connected to a controller for comparison with drive signals supplied to the infusion pump, to verify proper mechanical output operation of the pump.

A medication infusion system including an arrangement for monitoring the operation of said medication infusion system to ensure that said medication infusion system is operating properly to cause medication to be dispensed to a patient, said system comprising: a housing including means for mounting a syringe having a plunger therein; a lead screw mounted for rotation in said housing; a drive wheel for driving said lead screw; means for driving said drive wheel to rotate said lead screw; means mounted on said lead screw for pushing said plunger into said syringe to dispense medication when said lead screw rotates; a reflective member having a pattern of reflective and substantially nonreflective surface zones thereon, said reflective member being mounted on said drive wheel to displace said reflective and nonreflective surface zones in sequence past a predetermined point; and photoreflective sensor means for illuminating said predetermined point, and for detecting the level of reflection from said reflective member at said predetermined point to monitor movement of said reflective member with said drive wheel.
