Abstract: An automatically retracting safety needle assembly configured to receive a syringe. The assembly has distal and proximal ends, and comprises: a housing, with internal housing (IH), and a base wall. A moving sleeve (MOS): at least partially within the IH; having a flange wall; axially movable. A biasing element (BE), within the IH, biasing the MOS proximally. A syringe, receiving a plunger rod; movable axially within the IH, and coupled to the MOS. An activation fork (AF), partially disposed within the IH. AF has a guiding arm coupled with the IH and the MOS; preventing motion of the MOS during non-deployment state. An automatic retraction mechanism, retracting the syringe after injection. Deployment: advance plunger rod and the AF axially (distally), until AF guiding arm allows proximal movement of the MOS, retracting the syringe. Distal advancement of plunger rod is constant without an abrupt increase in resistive force; allowing safe disposal.

Abstract: Systems and devices for interfacing between a medicinal vial, a hypodermic needle, and an injection device such as a syringe, comprising a valve, functionally associated with said vial adaptor, said injection device port, and said needle, said valve having a first orientation wherein said injection device port is in fluid flow communication with said vial adaptor and a second orientation wherein said injection device port is in fluid flow communication with said hypodermic needle, wherein rotation of said injection device port between a first position and a second position thereof, drives transition of said valve from said first orientation to said second orientation.

Abstract: The invention provides a safe auto-needle device for injection, comprising: a main housing and a syringe-support receiving a disposable prefilled syringe terminating in a needle covered by a needle sheath (NS). The speed of depressing of the syringe plunger is manually controllable by a user. In a first embodiment, a locking mechanism is present, for preventing premature advancement of the needle. A second embodiment comprises an interlock, for preventing depressing of a plunger, prior to advancement of the syringe-support to a needle penetration location. Additional components include a drive mechanism; and a needle shield moveable between: a needle covered position; a partially exposed position, to a fully extended needle safe position. The invention also discloses a needle sheath (NS) remover.

Abstract: An automatic needle device comprises a body into which a needle assembly and needle are mounted. The device also includes a needle guard to cover the needle until it is used and to lock over the needle after use so the needle is not re-exposed. The locking is accomplished with a coil spring action locking device. A container for holding the automatic needle device also facilitates the viewing of the distal end of the needle prior to use on a patient.
