Patent attributes
A medication delivering injector having electrical sensor pads in communication with a microcontroller such that contact with the patient's skin and the angle at which the injector is held against the skin and the steadiness with which the injector is being held can be ascertained. A haptic vibrator and audio speaker produce a vibration which is variable in pitch in such a manner that biofeedback is provided to the injector user as to the pressure, angle and steadiness with which they are holding the injector. Multiplexed onto the electrical sensor pads, is a TENS (Transcutaneous Electrical Nerve Stimulation) generator which is operational (at the user's choice) just before and during the injection to interrupt or quench the pain of tissue perforation often accompanied with needle injections.
