  • Intradermal injector
    Patent number: 10646662
    Abstract: An injection device that comprises a chamber configured for containing a substance to be injected and a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an intradermal injection site. A collar surrounds the needle, defining a collar cavity. The collar also has a peripheral forward skin-contacting surface that surrounds and is radially spaced from the needle and injection site by an area that is sufficiently large to allow a patient's skin to move into the collar cavity to properly position the needle for intradermal delivery of the substance to the injection site to allow spread of the injected substance under the skin while inhibiting or preventing backpressure within the skin from forcing the substance out through the injection site.

  • Electromechanical manipulating device for medical needle and syringe with sensory biofeedback and pain suppression capability
    Patent number: 10576220
    Abstract: 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.
