摘要： An implant delivery syringe includes a barrel, a plunger assembly, and a barrel adapter. A barrel adapter mountable to a syringe barrel includes a barrel tip, needle retraction mechanism, needle assembly and stylet slidably disposed within the needle lumen. The needle retraction mechanism includes a biasing member, actuable locking arrangement and locking mechanism. When the actuable locking arrangement is actuated, the biasing member causes the needle to axially translate over the stylet during retraction to cause delivery of an implant to a target location. The stylet may be retracted following delivery. Methods of assembling, manufacturing, and using are also provided.

摘要： A mixing device and a retractable syringe comprising same are provided. The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

摘要： A syringe with a blocking structure includes a one-way engagement unit 5, 6, 7 having a propping portion 51, 61, 71, a flange 23, 24, 25 extended outwardly from a rod 4 and abutted with a cylindrical body 2, and a flexible bracket 52, 62, 72 extended outwardly from the rod 4 and isolated from the propping portion 51, 61, 71, and the flexible bracket 52, 62, 72 has an external diameter greater than the propping portion 51, 61, 71. When the rod 4 is moved forward with respect to the cylindrical body 2 to pass through the flange 23, 24, 25, the flange 23, 24, 25 abuts the flexible bracket 52, 62, 72 to tilt backward. When the rod 4 is moved backward with respect to the cylindrical body 2, the flange 23, 24, 25 abuts the flexible bracket 52, 62, 72 to tilt the flexible bracket 52, 62, 72 forward, and the propping portion 51, 61, 71 blocks the flexible bracket 52, 62, 72.

摘要： A tamper proof retractable non-reusable syringe has a one-piece hollow outer body (12) with a barrel (14) for a slidable plunger (32), a transition zone, and a smaller diameter nose portion (16). An elongated needle holder (22) and spring combination is installed from the rear of the outer body, guided into the nose portion and held by cooperating inwardly and outwardly facing surfaces oriented in the direction of retraction at the most constricted part of the transition zone where the nose begins. The plunger has an opening (41) with a dislodged stopper (42) for receiving parts of the retraction mechanism. The stopper and the head of the needle holder are of significantly reduced diameter from the injection fluid chamber to resist blowing out prematurely. In one embodiment the head of the needle holder is surrounded by a separable retainer member which is sliding removed by contact with the tip of the plunger after the stopper is mostly or fully removed to avoid cumulation of force required for retraction after the injection. In a second embodiment the head of the needle holder is clamped, and held by constricting forces imposed by stress on the outer body induced by interference fit. Release occurs by slight expansion on the barrel by contact of the plunger tip with a small internal ramp in the outer barrel. Both embodiments have a plunger cap configured to enter an opening in the outer body to provide an additional tamper proof feature. The retraction cavity is provided with venting structures to assure that all uninjected fluid is retained within the syringe body.

摘要： A retractable needle device attachable to the front of a fluid collection or infusion device such as a syringe, the retractable needle device comprising a housing having an engagement member, a slide support surface, a retraction cavity and a first pinch surface; a needle; a needle alignment member comprising a needle tube and a second pinch surface; and a needle retraction mechanism positioned within the needle tube and configured to bias the needle rearwardly; wherein the first and second pinch surfaces are configured so that a pinching force applied to them will cause relative lateral movement between the housing and needle alignment member. This translational movement from an injection position, wherein the needle is aligned with the syringe connector, to a retraction position, wherein the needle is aligned with the retraction cavity, allows the needle retraction mechanism to force the needle into the retraction cavity.
