摘要： A dual chamber syringe, comprising a syringe barrel having a forward end, a rearward end and at least one bypass protrusion arranged along the longitudinal extent of the syringe barrel; a finger grip element coupled to the rearward end of the syringe barrel, the finger grip comprises at least one protrusion extending radially inwardly from an inner surface thereof; a plunger rod operatively coupled with the finger grip element; a guiding track is formed on the plunger rod and comprises a helical track portion and a longitudinal track portion; and wherein upon relative displacement of the plunger rod and said finger grip element, the at least one protrusion is guided along the guiding track.

摘要： A syringe assembly, comprising a syringe barrel having a forward end and a rearward end and being arranged along a longitudinal axis; a restricting element, moveably supported onto a portion of the syringe assembly and positionable in one of an injection disabling position and an injection enabling position in different operative orientations of the syringe assembly; a plunger rod assembly displaceable within the syringe barrel and operatively coupled with the restricting element; the plunger rod assembly having a restricting feature adapted to cooperate with the restricting element, such that when the restricting element in the injection disabling position, the plunger rod assembly is permitted to be displaced axially forwardly only up to a certain longitudinal extent relative to the syringe barrel and when the restricting element is in the injection enabling position, the plunger rod assembly is permitted to be further displaced axially forwardly relative to the syringe barrel.

摘要： An automatically retracting safety needle assembly configured to receive a syringe; and a method of use. 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, and 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 to overcome for activating the retraction; allowing safe disposal.
