ABSTRACT:
A disposable, single-use, medication charged syringe is described wherein the syringe body is formed with a tubular glass barrel having a steel needle mounted on the barrel by means of a tubular glass bead. The beading and barrel are initially made from common stock of right circular hollow cylindrical tubes. The syringe body is formed by a number of steps including a barrel flaring operation and a needle attaching operation in which the needle is first sealed to the glass tubular bead before the glass bead is sealed to the glass barrel. Identification of the syringe and the particular unit dose therein is provided by a flared colored plastic gripping sleeve which is slipped over the glass barrel.
