Title: Needle reinforcing means for small gauge hypodermic needles

Abstract: A support device for a hypodermic needle particularly useful in dental surgery. One part of the support device is a funnel-like structure adapted to fit over the base of the hypodermic needle, and the other part consists of a siding tip guard adapted to slide coaxially inside the funnel-like structure in the manner of an expansible telescope. Both the funnel-like structure and the tip guard have longitudinal openings therethrough, inside which the hypodermic needle is placed. At the end of the tip guard, away from the funnel-like structure, there is an enlarged hub adapted to press against the gum in the mouth of the patient and through which the hypodermic needle is inserted, through the gum and into the bony structure below.
