First Claim
Patent Images
1. An infusion device, comprising:
- a housing having a reservoir that is sized to retain a quantity of liquid medicament;
a mechanical pump that displaces a portion of the liquid medicament when mechanically actuated;
a mechanically driven activation mechanism disposed on the housing for actuating the pump in order to deliver a dose of liquid medicament and thereby signifying a dose event; and
an energy generator coupled to the activation mechanism, the energy generator being configured to generate energy upon each operation of the mechanically driven activation mechanism in order to power a dose counter that is configured to record dose events.

Abstract
A medical device with a self-sustaining power source is disclosed herein. The medical device includes a pump and at least one mechanical activation mechanism for engaging the pump to cause a dose event. An energy generator coupled to the activation mechanism generates energy each time the activation mechanism is actuated. The generated energy is supplied to a dose counter of the infusion device.
