    摘要： The present embodiments provide for a syringe and a retraction plunger assembly configured to accept various retractable needle assemblies, which are capable of cooperating to provide a retraction safety syringe. In particular, the syringe includes a barrel and a retraction plunger assembly comprising a control unit attached to a plunger and releasably engaged to a housing, and at least one biasing means disposed within the plunger assembly. Upon completion of dose delivery via a retractable needle, the control unit disengages from housing and the biasing member retracts the plunger and a connected needle into the barrel. Various elements are configured to prevent further use of the syringe. The control unit can be used to control a rate of needle retraction.

    摘要： A retractable safety syringe includes a retractable needle hub holding a needle and having a first guiding means; and a hollow barrel having a second guiding means set correspondingly to the first guiding means; and a collapsible plunger comprising of a first plunger element having a protrusion releasably coupled with a second plunger element having a longitudinal slot with a pinched zone to curb the movement of said protrusion; and a spring disposed between the needle hub and hollow barrel and acts between the needle hub and the hollow barrel. The uncoupling of the collapsible plunger triggers the retraction mechanism to enable the needle hub to retract into the barrel by the decompression force of a spring. The reliability of retraction is further improved by a longitudinal slot and a protrusion to facilitate the retreating of the collapsible plunger in an orderly way.

    摘要： The present invention relates to a security syringe comprising a hollow cylinder (1) with a pair of wings (11) and a tip (12), which houses: the injection mechanism (3), a piston (2), and an injection mechanism (3) with a needle (31), a spring (32) and a membrane (33). The piston (2) has a serrated crown in the lower part (21) thereof where a chamber seal exists (22) and breaks only with the interior point of the needle (31), having the ends of the piston (2) of an inferior disk (24) and a superior disk (25) that steadies the piston (2) inside the cylinder (1). Around the cylinder (1) there is a protective funnel (13) against accidental injections. The piston comprises a cap (26) which guarantees the hermeticity of the empty chamber.

    摘要： The present invention relates to a prefillable drug delivery device (1), comprising :
    - a housing (10) receiving a needle hub (20) movable with respect to said needle hub between a retracted position and a protection position,
    - a tubular barrel (30) intended to receive a drug, and pre-mountable on said housing so that said needle hub closes its distal end,

    said device further comprising sealing means (22, 31) actionable once said tubular barrel is pre-assembled on said housing, capable of going from an inactive state where no sealing contact is present between said needle hub and said tubular barrel, to an active state, in which sealing contact is performed,
    wherein, in the active state of said sealing means, said tubular barrel is movable in translation with respect to said needle hub between a proximal position and a distal position, for realizing delivery of the drug.
