Abstract
A hypodermic syringe employing a plunger slidably disposed within a barrel. The plunger has a mounting hole extending through the seal end thereof to receive a mandrel. The mandrel has a flexible flange to be releasably engaged with the plunger. A spring element withdraws the mandrel into a cavity within the plunger upon full extension of the plunger within the barrel. The barrel includes a hub retainer at the forward end thereof and a needle hub retained therein the mandrel includes barbed tines with surfaces having axes of the conical surfaces that are displaced from one another such that movement of the tines toward one another also brings the axes closer. A catch associated with the back end of the spring element coupled with the mandrel at the other end cooperates with shoulders on smooth surfaces within the cavities to retain tension within the bungee. The hub retainer and the needle hub cooperate to insure that the needle hub is constrained to limited motion such that the mandrel will fully engage the needle hub.
