A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

Devices and methods for a compact injector are provided with a compact configuration for ease of carrying or storage, and an activated configuration ready for injection. In the compact configuration, a plunger and a needle are both retracted into the injector housing, and upon actuation to the activated configuration, the plunger extends proximally and the needle extends distally, ready for injection. An extendable needle shield is also provided to block visibility of the needle during injection, and to reduce the risk of inadvertent needle stick at other times, including disposal.

An injection device includes a lower housing, a needle guard and an upper housing. With the upper housing in a pre-use position and the needle guard in a first position, an abutment body of an arm of the upper housing abuts a catch of the lower housing, preventing the upper housing from moving distally relative to the lower housing toward a dispensed position. Proximal movement of the needle guard from the first position to a second position thereof causes proximal movement of a camming ramp of a leg of the needle guard with respect to the catch and the abutment body such that the camming ramp engages the arm, thereby deflecting the abutment body radially outwardly by a distance sufficient to allow the abutment body to pass radially outside of the catch, and, in turn, permits distal movement of the upper housing into the dispensed position of the upper housing.

An autoinjector includes a housing, a needle guard mounted axially moveable in the housing for movement between a storage state, a dispensing state and a lock-out state in which states the needle guard adopts different axial positions relative to the housing, with the needle guard being configured to be axially moved in a proximal direction between the dispensing state and the lock-out state.

An autoinjector basically includes a housing, a pre-filled syringe, a drive chassis, and a needle guard. The pre-filled syringe is mounted in the housing. The drive chassis is configured to move a plunger in the pre-filled syringe to dispense medicament via an urging force from a drive spring. The needle guard is moveable in the housing between a storage state, a dispensing state, and a lock-out state. The needle guard is biased towards an extended position by a lock-out spring. The needle guard selectively engages the housing to establish a frontmost position of the needle guard in the storage state, and an offset position of the needle guard in the lock-out state. The offset position is axially offset from the frontmost position in the distal direction.

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.

The safety device includes a tubular body extending along a longitudinal axis. The tubular body is configured to receive the medical container, a needle cover movable relative to said body between a retracted position, and an extended position in which the needle cover distally extends from the retracted position in order to shield the injection needle after activation of the safety device, a release element configured to move the needle cover from the retracted to the extended position after activation of the safety device, and a retainer for maintaining the release element in a compressed condition when the needle cover is in the retracted position. The retainer is configured to transmit a user's activation force to the needle cover once the injection operation is completed. The needle cover includes a distal abutment surface, said distal abutment surface abutting against a proximal abutment surface of a bump protruding from the body in the retracted position of the needle cover. The bump extends in a circumferential direction according to a central angle comprised between 22.5°-45°.
