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.
