Abstract
A medical device with a capacitive sensing function includes a medical body having a syringe and a sensing circuit having an electrode, a protective film adhered to the medical body and including a plastic film, an electrode provided on the plastic film and opposite from the electrode of the medical body, and a capacitive sensor formed by the electrode of the medical body and the electrode of the protective film and being a part of the sensing circuit, wherein a capacitance value of the capacitive sensor changed under the condition of removing the protective film from the medical body, the sensing circuit being configured to detect the capacitance value and trigger corresponding function of the medical body.
