Abstract
A safety holder for a pre-filled medical syringe cartridge includes a barrel tube with a hinged locking gate and a safety sleeve. In one embodiment of the invention, the safety sleeve is a separate piece having interior surface projections and the barrel tube is provided with longitudinal and circumferential tracks on its outer surface. The separate safety sleeve slides over the barrel tube so that the interior surface projections engage the tracks. The tracks are provided with various locking configurations which engage the interior surface projections of the sleeve to hold it in a non-safety position while the syringe is being used and lock it in a safety position after use. A second embodiment of the invention includes an integral non-movable safety sleeve for use with IV administration line ports.
