Abstract

An instrument, article and method are provided for minimizing pain during administration by injection of a liquid, such as, an anesthetic. The instrument has a forward end. A rod or lightpipe mounted freely for vibration projects out of the forward end. The article, a single use tip, is composed of a tip sleeve removably mounted on the forward end of the instrument and a tip member removably mounted on the projecting rod or lightpipe to vibrate a preselected injection site on a human or animal. The tip sleeve and tip member are covered by an elastic overmold that enables the tip member to vibrate freely with respect to the tip sleeve and light from the lightpipe to illuminate the injection site. The overmold of the single use tip is torn during removal of the single use tip from the instrument.

Claims

1. A method for reducing pain associated with a skin-puncturing procedure of tissue of a human or an animal, the method comprising:

providing an instrument having;

(a) a main body having a forward end;

(b) a lightpipe projecting from the forward end of the main body;

(c) a single-use tip having a tip sleeve removably mounted on the forward end of the main body and a tip member removably mounted on the lightpipe;

and

(d) an elastic overmold covering the tip sleeve and the tip member;

selecting a puncture site on the tissue;

creating vibrations in the main body;

transmitting the vibrations through the lightpipe to the tip member to vibrate the tip member;

applying the tip member to the tissue at the puncture site, while the vibrations are transmitted through the lightpipe to the tip member, whereby the tissue is vibrated at the puncture site;

puncturing the tissue with a needle at the tissue puncture site, wherein vibrating the tissue facilitates pain reduction during the puncturing; and

upon completion, tearing the elastic overmold from the tip such that the tip cannot be reused.

2. The method according to claim 1, wherein tearing the elastic overmold includes rotating the tip sleeve while the tip member remains stationary.

3. The method according to claim 1, further comprising illuminating the injection site by activating the lightpipe.

4. The method according to claim 1, wherein creating the vibrations includes creating continuous vibration.

5. The method according to claim 1, wherein creating the vibrations includes creating pulsed vibrations.

6. The method according to claim 5, further comprising creating pulsed vibrations according to a pulsing duty cycle of 1.05 seconds with about one second on and about 0.05 seconds off.

7. The method according to claim 1, wherein creating the vibrations includes creating vibrations in an amplitude of about 0.1 mm to about 1.0 mm.

8. The method according to claim 1, further comprising continuing vibration of the tissue at the puncture site after the puncturing is complete.

9. The method according to claim 8, further comprising applying increased pressure to the tissue.

10. The method according to claim 9, further comprising contacting bone underlying the tissue with the increase pressure.

11. The method according to claim 10, further comprising maintaining pressure for at least 1 and up to about 90 seconds after the bone is contacted.
