Method for reducing pain during skin puncturing procedures
First Claim
1. A method for minimizing pain during administration of a liquid into tissue of a human or an animal, the method comprising:
- providing an instrument having;
(a) an elongated, tubular body having a rear end and a forward end;
(b) a vibration unit mounted in the elongated, tubular body to transmit vibrations; and
(c) a detachable tip composed of hard plastic and configured to enable retraction of any overlapping tissue or skin to expose an injection site and having a rear portion and a forward portion, the rear portion coaxially detachably mounted on the forward end of the elongated, tubular body to extend forward axially with respect to the elongated, tubular body and to receive the vibrations transmitted from the vibration unit, and the forward portion having a bifurcation forming two forwardly extending spaced projections that define a space therebetween, the two forwardly extending spaced projections spaced between about ⅛
inch to about 1 inch apart;
selecting an injection site on the tissue;
retracting any overlapping skin or tissue with the disposable tip to expose the injection site;
bracketing the injection site between the two forwardly extending spaced projections, each of the two projections directly contacting the tissue on opposite sides of the injection site;
activating the vibration unit to generate vibrations, the vibrations transmitted from the vibration unit through the detachable tip to the tissue by direct contact of the two projections with the tissue, whereby the tissue is vibrated at the injection site; and
administering the liquid by injection with a needle into the tissue at the injection site, wherein the administering step occurs simultaneously with the tissue being vibrated at the injection site and vibrations transmitted to the tissue cause vibratory stimulus to nerves adjacent to the injection site to thereby minimize pain during administration of the liquid.

Abstract
A handheld instrument for minimizing pain during administration by injection of a liquid, such as, an anesthetic that has a main body, a vibration unit mounted in the main body when initiated to cause the main body to vibrate, and a detachable tip cantilever mounted on the main body to vibrate with it, the tip having a free end characterized by a bifurcation to form two spaced projections defining a space between them, whereby the spaced projections can be placed in proximity to, adjacent to and bracketing a preselected injection site on a human or animal and the tissue at said preselected injection site and vibrated while an injection is given.

6. A method for minimizing pain during administration of a liquid into tissue of a human or an animal, the method comprising:
-
providing an instrument having; (a) an elongated, tubular body having a rear end and a forward end; (b) a vibration unit mounted in the elongated, tubular body to transmit vibrations; (c) a detachable tip composed of hard plastic and configured to retract any overlapping tissue or skin to expose an injection site and having a rear portion and a forward portion, the rear portion detachably coaxially mounted on the forward end of the elongated, tubular body to extend forward axially with respect to the elongated, tubular body and to receive the vibrations transmitted from the vibration unit, and the forward portion having a bifurcation forming two forwardly extending spaced projections that define a space therebetween, the two forwardly extending spaced projections spaced between about ⅛
inch to about 1 inch apart; and(d) a light configured to illuminate the space between the two forwardly extending spaced projections; selecting an injection site on the tissue; retracting any overlapping skin or tissue with the detachable tip to expose the injection site; bracketing the injection site between the two forwardly extending spaced projections, each of the two projections directly contacting the tissue on opposite sides of the injection site; illuminating the injection site in the space between the two forwardly extending spaced projections by activating the light; activating the vibration unit to generate vibrations, the vibrations transmitted from the vibration unit through the detachable tip to the tissue by direct contact of the two projections with the tissue, whereby the tissue is vibrated at the injection site; and administering the liquid by injection with a needle into the tissue at the injection site, wherein the administering step occurs simultaneously with the tissue being vibrated at the injection site and vibrations transmitted to the tissue cause vibratory stimulus to nerves adjacent to the injection site to thereby minimize pain during administration of the liquid. - View Dependent Claims (7, 8, 9, 10)
