Abstract

See full text

Syringes are disclosed herein incorporating a variety of safety mechanisms for protecting the users from accidental needle stick. In certain embodiments, the syringes incorporate retractable carriages that can be retracted into the syringe barrels by engaging with the plungers. The carriages are configured to receive different needle hubs having any number of needle sizes. In certain other embodiments, the carriages are spring loaded so that as the plungers disengage the carriages from the syringe barrels, the springs automatically retract the needles into the barrels. Still in certain other embodiments, needle hubs with spring loaded needles are used with the syringes. The needles are retracted into the barrels when the plungers activate certain mechanisms incorporated into the hubs to thereby release the needles.
