A device that is used in conjunction with a needle-based medication injection device (e.g. a prefilled syringe) that prevents needle stick injuries. The used needle is shielded by a needle guard that surrounds and extends beyond the needle tip. In a preferred embodiment, before the needle is inserted into the patient, the needle guard projects forward to substantially hide visibility of the needle for safety and to reduce patient anxiety.

Patient-contact activated needle stick safety device

The present disclosure describes a needle guard device or system that can be used with drugs requiring reconstitution. The needle guard is preferably a passive needle guard that can be used during reconstitution without activating the safety mechanism. Following administration of the medication, the needle guard shields a user from inadvertent needle sticks by extending a protective shield over the needle.

Reconstitution means for safety device

The present disclosure describes an extended finger flange that facilitate use of syringe systems. The extended finger flange increases the surface area available for an end user's fingers thereby allowing a more secure grip on the device and providing greater control during administrations of the medication.

Extended finger flange for syringe systems

A folding panel needle guard comprises front and rear panels coupled together at hinges, a collar attached to the front panels at hinges, a guard base element coupled to the rear panels at hinges, a hub and a spring to unfold and lock the front and rear panels in a co-linear needle shielded configuration. The folding panel needle guard is mountable to a needle or syringe assembly.

Folding panel needle guard

A safety device for a medicine cartridge comprising a body for receiving a cartridge, a guard for covering a used needle, a plunger to dispense medicine from the cartridge and a spring for activation of the guard. The trigger fingers of the guard are spaced to avoid or minimize contact with the spring flange during assembly to avoid trigger finger unseating. An elongated trigger finger head enables the device to activate for all known syringe and syringe plunger tolerances. The spring end coils have larger diameter than the inner coils to reduce the likelihood of the spring end coil end interfering with the cartridge subassembly. Syringe capture features are configured to retain a syringe having a small round or conventional cut flange in place during use and reduce the stress on the syringe flange during insertion while maintaining the ability to hold the syringe in place during use.

Anti-needle stick safety device for injection device

Anti-needle stick safety device or system for use with drugs requiring reconstitution

The present invention provides an injection device including a syringe having a distal end for receiving a needle, and a plunger inserted into a proximal end. A guard is slidable on the syringe, has a proximal end, a distal end, and is biased from a first position wherein the needle is exposed toward a second position wherein the guard covers the needle. The syringe includes a body having a central cylindrical opening for receiving a medicine and the plunger, and further includes a pair of longitudinally extending members on opposite sides of the body. The injection device includes cooperating detents for retaining the guard and syringe in the first and second positions. A latch member is engageable by the plunger as the plunger is depressed to release the cooperating detents. Upon release, a spring element biases the guard toward the second position.

Syringe with needle guard injection device

A passive needle safety device for protecting the needle of an injection syringe after medication has been delivered to a patient comprising a body that can hold a syringe, a telescoping guard fitting over the body, and a spring deployed between the guard and body such that the guard is urged in an extend configuration distally relative to the body, the improvement comprising, trigger fingers for holding the guard and body together in an un-extended configuration against the force of the spring, and a plunger rod with a plunger head which pushes against the trigger fingers, the head having an angled surface that provides a lateral component of force to the trigger fingers to displace them from the latched configuration to an unlatched configuration.
