Light for Oral Anesthesia Injection Syringe

摘要

A light for use with an oral anesthesia syringe that is received into a passageway of a barrel of the light. When the syringe is received into a first opening in a proximal end of the barrel's passageway, the needle of the syringe extends through a second opening at the proximal end of the barrel. A plurality of lamps at the distal end of the barrel illuminate the needle, the interior of a patient's mouth, and an injection site of the needle. A battery is included in the light for powering the lamps. Power is selectively applied to the lamps. A circuit may disable illumination after about ten minutes of use.

主权项

1. In combination, an oral anesthesia injection syringe having a needle extending therefrom and having a tubular body with a certain body outer diameter, and a light, said light comprising:
(a) a barrel having a proximal end and a distal end, said barrel having a first opening at said proximal end and a second opening at said distal end and a longitudinal passageway through said barrel from said first opening to said second opening, said passageway having a transverse inner diameter larger than said certain body outer diameter; and (b) an electrical circuit including:
i. a plurality of lamps proximate said distal end of said barrel and encircling said second opening; andii. a battery received into a compartment of said barrel for powering said plurality of lamps; said tubular body of said syringe being received within said passageway with said tubular body of said syringe extending through said first opening and with said needle extending out of said second opening, with said plurality of lamps, when powered by said battery, illuminating said needle and an injection site of said needle.
