Abstract:
1. An instrument for minimizing pain during administration by injection of a liquid, such as, an anesthetic comprising (a) an elongated main tubular body having a rear end and a forward end; (b) a vibration unit mounted in the main body to transmit vibrations; (c) a detachable elongated tip composed of hard plastic and having a rear portion and a forward portion; (i) the rear portion of said tip configured and dimensioned to match and be mountable on the forward end of the main body; (ii) said tip, via said rear portion, being cantilever coaxially detachably mounted on the forward end of the main body so that the tip extends axially forwardly and terminates in a free end; (iii) the forward portion of said tip adjacent its free end transitioning to a retractor portion; (d) two spaced, forwardly extending, short projections of hard plastic spaced between about ⅛ inch to about 1 inch apart and of smaller cross section than the cross section of the free terminal forward end of said elongated tip for receiving vibrations transmitted from the vibration unit in the main body, each said projection having a rear end fixed to the free terminal forward end of said tip and extending forwardly and terminating in a free rounded end, said projections lying in close proximity while defining a free space therebetween; (e) a soft plastic or rubber coating covering the free forward end of each said projection; (f) whereby the free forward ends of the two forwardly extending spaced projections of the detachable tip covered by soft plastic or rubber coatings can directly contact tissue at a proposed injection site on a human or animal and vibrate the tissue while an injection is given juxtaposed to the spaced projections.
