MEDICATION DELIVERY DEVICE WITH SENSING SYSTEM

Abstract:

Medication delivery devices are provided having a sensor in the form of a switch having a conductive pad and a cantilevered arm that is moveable toward and away from the conductive pad. Contact between the cantilevered arm and the conductive pad changes the state of the switch, while lack of contact between the cantilevered arm and the conductive pad changes the state of the switch. The switch may be used to sense dosage of medication delivered during dose delivery. The switch may interact with a rotating component having a plurality of teeth that slide against the cantilevered arm during dose delivery.
