The sensing means employs the casing of the device, the body of the patient, and the needle in a circuit which activates electrical means for notifying the physician of needle placement. Contact of the hypodermic needle with the desired location in the reservoir completes a circuit which is activated by power means to provide preferably audible feedback.
