Method and apparatus for performing injections while vibrating the skin

Abstract

An apparatus is provided for performing an injection, the apparatus including a front end, a vibrator mechanism selectively vibrating the front end during an injection and a syringe holder holding a syringe during an injection through the front end while the front end is vibrated.

1 . An injection apparatus for injecting a patient with a liquid using a standard syringe including a needle, a barrel receiving said needle with a needle tip at one end and being adapted to hold the liquid, a reciprocating piston disposed in said barrel for selectively ejecting said liquid through the needle tip, said injection apparatus comprising:
 An elongated housing with a longitudinal axis having a front section with a front section outer wall and rear wall and a plurality of internal chamber including a motor chamber, a battery chamber and a syringe chamber, said motor chamber being disposed behind said front section outer wall, said battery chamber being disposed behind said motor chamber, said syringe chamber extending in parallel with said motor and said battery chamber and including an aperture sized and shaped to accept the standard syringe into said syringe chamber a front section, said front section having an opening extending through said front section wall, and arranged to allow the needle to be selectively extended from the housing for administering of an injection;   a battery disposed in the battery chamber; and   a vibrating motor disposed within said motor chamber and powered selectively by said battery, said motor being adapted to selectively vibrate said front section outer wall at least in the vicinity of said opening during said injection to thereby reduce pain that may be felt by the patient during the injection.

         3 . (canceled) 
     
     
         4 . The apparatus of  claim 1  further comprising an offset weight, said vibrating motor rotating said off-set weight to cause the vibration of said housing, said apparatus further including a switch selectively activating said motor. 
     
     
         5 . (canceled) 
     
     
         6 . The apparatus of  claim 1  further comprising a syringe holder extending through said aperture and configured to hold the syringe, the syringe holder being selectively movable between a first position in which the syringe needle is disposed inside the housing and a second position in which needle extends outwardly of said housing. 
     
     
         7 - 9 . (canceled) 
     
     
         10 . An injection apparatus receiving a standard syringe with barrel with two opposed barrel ends, one barrel end receiving a syringe with a syringe tip, the other barrel end receiving a piston with a piston shaft for selectively reciprocating the piston to eject fluid from the barrel through the needle tip, the apparatus comprising:
 An elongated housing with a front section with a front section wall and a rear section with a rear section wall, said housing including a syringe chamber extending longitudinally through said housing between said front section wall and said rear section wall, with an aperture sized and shaped to receive the needle tip and allow said needle to be extended selectively outwardly from said syringe chamber, said syringe chamber further including a rear aperture formed in said rear section wall, said housing further including a motor chamber oriented in parallel with said syringe chamber;   A syringe holder extending into said syringe chamber through said rear opening, said syringe holder being sized and shaped to receive said syringe and to selectively advance the syringe into said syringe chamber with the syringe tip being selectively advanced to exit through said aperture; and   A motor disposed in said motor chamber and cooperating with said housing to selectively vibrate said front section wall while the syringe tip extends outwardly of said housing through said aperture deaden sensation in a patient's skin during an injection.
