ABSTRACT:
An improved medication infusion pump is provided of the type for receiving and supporting a medication-containing syringe, wherein the pump and syringe include matingly interfitted components to ensure use of the pump with a compatible and correctly installed syringe. The infusion pump comprises a pump housing defining a syringe compartment for receiving and supporting the syringe, in combination with a drive member for engaging and programmably displacing a syringe plunger to administer medication to a patient. In one preferred form, the drive member and plunger include a matingly interfitting tab and notch which are engaged when the syringe is fully and properly positioned within the syringe compartment. In another form, the tab and notch are formed on the syringe plunger and a portion of the pump housing.
