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.本文揭示一種具有自給電源的醫療裝置。該醫療裝置包括一泵及至少一機械啟動機構，該機械啟動機構用於嚙合該泵以引發一給藥事件。每當該啟動機構被致動時，耦接至該啟動機構的一能量產生器就產生能量。該所產生之能量被供應至該輸液裝置之給藥計數器。
