A wedge element may be frictionally engaged to the ferrule and a distal end of the syringe body. To retract the needle into the syringe body, a punch of a piston displaces the wedge element off of an annular flange of the ferrule. At about the same time, longitudinally offset tabs engage an annular flange and retract the needle into the syringe body via a retraction force created by a variable vacuum compartment or tension member. Alternatively, the ferrule and needle may be temporarily fixed to the distal end of the syringe body via a detent and/or o-ring which engages a lower undercut groove and an upper undercut groove of the ferrule. An annular ring of the piston may have longitudinal offset tabs which engage an annular ring of the ferrule.

  • Patent number: 8622961
    Abstract: A safety needle assembly is provided herein which includes a displaceable locking tongue which has a first position in which the locking tongue covers an aperture formed in a shield so as to prevent the passage therethrough of a needle. A biasing element is also provided for urging the locking tongue to the first position. The locking tongue is releasably retained in a retained position prior to use of the safety needle assembly, the aperture being sufficiently uncovered with the locking tongue being in the retained position so as to permit passage of the needle through the aperture. The locking tongue is releasably retained in the retained position against biasing force of the biasing element. With the shield being displaced proximally from a first position to a second position, the locking tongue is released from the retained position and permitted to be displaced to the first position under force of the biasing element.

  • Patent number: 8617119
    Abstract: A safety device having a tubular support for a needle mount end and a protective shield slidably mounted on the support from a set position, a retracted position and then to a locked position to covers the needle. A locking member mounted on the support, within the shield and a cam follower is engaged with a cam profile on the locking member. Forward axial movement of the support relative to the locking member causes the locking member to rotate relative to the support. The shield has a guide defining a shoulder towards its rearward end and an abutment on the locking member is receivable behind the shoulder when the shield is in its locked position. A spring acts such that when the locking member is turned to engage its abutment with the shoulder of the shield when the latter is in its locked position, so preventing subsequent rearward movement thereof.

  • Publication number: 20130317446
    Abstract: The invention relates to an auto-injector for administering a dose of a liquid medicament, comprising: an elongate housing arranged to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, wherein the syringe is slidably arranged with respect to the housing, spring means capable of, upon activation: pushing the needle from a covered position inside the housing into an advanced position through the orifice and past the proximal end, operating the syringe to supply the dose of medicament, and retracting the syringe with the needle into the covered position after delivering the medicament, activating means. The spring means is a single drive spring arranged to be grounded at a distal end in the housing for advancing the needle and for injecting the dose of medicament via a plunger. The drive spring has its ground in the housing switched to its proximal end for retracting the syringe. An interlock sleeve is telescoped in the proximal end of the housing.

    Abstract: A syringe which disperses medicate across a zone in the body during apparent conventional operation. The improved syringe includes a barrel, a plunger, and an operating cylinder. In operation, the needle of the syringe is inserted into the body at the distal portion of the portion of the body which is to receive the medicate. A single arm is attached to the barrel and passes through an operating cylinder with a thumb rest on its top. As a result, in operation, the user draws the single arm up to the thumb rest, thus causing the syringe to withdraw during injection and leaving a patch of medicate during operation.
