Abstract
A vibrating injection device includes a housing formed with an interior chamber for releasably housing a conventional syringe therein and further including an opening on one end thereof. A syringe vibrating motor is also disposed in the interior chamber adjacent the syringe to vibrate same. A plunger drive motor is housed in the interior chamber and is connected to the plunger of the syringe to manipulate the plunger to expel the contents of the syringe through the needle.

13. Hand held vibrating and injecting apparatus for housing a syringe including an injection needle and plunger comprising:
-
a hand held housing formed with an interior compartment and having an opening in one end; a syringe including a barrel having a compartment for storing fluid therein and a needle having a sharp penetration point; a mounting device in said compartment for releasably mounting said syringe for projection of said injection needle through said opening; an electrically powered vibrator mounted from said housing for vibrating said syringe and needle; a drive assembly housed in said housing and configured for engagement with said plunger and operative to drive said plunger relative to said syringe to expel said fluid from said barrel through said needle; and a power source housed in said interior compartment and electrically connected to said vibrator and to said drive assembly for supplying electric power to said vibrator and to said drive assembly. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for penetrating a patient'"'"'s tissue and for diminishing the pain while penetrating said tissue with a syringe device and injection needle formed with a sharp tip, said method including the steps of:
-
selecting a vibrator device including a vibrator for vibrating said needle at a predetermined frequency effective to, when applied to a patient'"'"'s said tissue, impart a degree of numbness to said patient'"'"'s nerves; mounting said syringe to said vibrator device to, when said vibrator is actuated, vibrate said sharp tip at said predetermined frequency; and actuating said vibrator device while advancing said needle into said tissue to vibrate said tissue with said needle.

22. A method for penetrating a patient'"'"'s tissue with a syringe and injection needle formed with a sharp tip, said method including the steps of:
-
selecting a vibrator device including a mount for receiving said needle and a vibrator for vibrating said needle in a path to cause said sharp tip, as it penetrates said tissue, to make short cutting strokes in said tissue in a direction transverse to the axis of said needle; mounting said syringe in said vibrating device; and actuating said vibrator and advancing said device toward said tissue to cause said sharp tip to penetrate said tissue as said sharp tip is moved through said short cutting strokes.

23. A vibrating injection device holding and vibrating a syringe including a plunger and an injection needle having a sharp tip, said device comprising:
-
an elongated housing formed with an interior compartment; a mount assembly for mounting said syringe in said housing with said needle projecting from said housing; a vibrator mounted in said housing and including a motor for vibrating said syringe and needle; a plunger drive device including a threaded drive rod and an actuator motor for driving said drive rod; a coupling comprising a plunger coupling clip formed with a threaded through bore for threadedly engaging said drive rod and further formed with a slot for releasably engaging said plunger; at least one battery in said housing; and a control switch on said housing electrically coupled to said battery, vibrator and actuator motor for selectively delivering power from said power source to said motor of said vibrator device and actuator motor. - View Dependent Claims (24, 25, 26)
