    摘要： 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.

    摘要： Catheter insertion device, comprising a catheter hub (1) at the proximal end of a catheter (Ia), a tubular needle hub (4), at which a hollow needle (5) is fixed which extends through the catheter hub and the catheter (Ia) in a ready position such that the needle tip (5.1) projects over the distal end of the catheter (Ia), a protective barrel (3) which is received in the tubular needle hub (4) in the ready position and is releasably connected to the catheter hub (1), and a pressure spring (6) arranged between the needle hub (4) and the protective barrel (3) and which displaces the needle hub (4) and the protective barrel (3) apart from each other in axial direction, wherein a manually operable holding member (3.5) is provided between the needle hub (4) and the protective barrel (3), and holds the needle hub (4) in the ready position at the protective barrel (3) against the bias of the pressure spring (6), so that after the holding member (3.5) is released, the pressure spring (6) moves the needle hub (4) into a protective position in relation to the protective barrel (3), in which position the needle is positioned in the protective barrel (3).
