  • Patent number: 10702663
    Abstract: 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.

  • Patent number: 10646657
    Abstract: 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.

  • Patent number: 10314985
    Abstract: 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.

  • Patent number: 10272209
    Abstract: The present disclosure describes anti-needle stick safety mechanism that is passively activated during the normal course of giving an injection. In one embodiment, the device includes a spring member coupled at a proximal end to a needle member and at a distal end to a needle cover. The passive activation of the device is triggered when the needle is inserted to a minimum depth into the patient's tissue to unleash the force of a compressed spring to urge a needle cover towards the distal end of the needle. As the needle is withdrawn from the tissue, the needle cover advances to the end of the needle and as it partially clears the end of the needle, it adopts an orientation that prevents the needle tip from re-emerging from the needle cover.

  • Patent number: 10188804
    Abstract: A needle guard device mountable to a pre-filled syringe in its ready-to-fill state. The device includes a lock collar and a device shield biased to move relative to the lock collar. The lock collar interfaces with the syringe neck to attach the device to the syringe. With the removal of a needle shield assembly comprising rigid and soft needle shields, the lock collar and device shield are free to move proximally along the syringe neck and interact with a syringe step down area to activate the device. As the device moves proximally, retention arms of the device shield interact with the syringe step down, causing the arms to deflect radially outwards to disengage from the lock collar triggering the device shield to move from a first position to a second position.

  • Patent number: 10159805
    Abstract: A needle guard device mountable to a pre-filled syringe in its ready-to-fill state. The device includes a device shield interconnected to a lock collar with flexible member and biased to move relative to the lock collar. The lock collar interfaces with the syringe neck to attach the device to the syringe. As the device shield moves proximally, rotation arms of the lock collar interact with angled cutouts in the device shield, causing the device shield to rotate relative to the lock collar and disengaging one or more keys on the device shield from one or more keyways in the lock collar triggering the device shield to move from a first configuration in which the device shield is retractable to expose a syringe sharp to a second configuration in which the device shield is fixedly positioned to cover the syringe sharp.

  • Patent number: 10052438
    Abstract: A medicine injection device comprises a cartridge having a cartridge barrel and a plunger having a plunger shaft slidable within the cartridge barrel. The cartridge may have, e.g., a pre-filled medicine. The medicine injection device further comprises a body having a proximal end, a distal end, and a cavity in which the cartridge barrel is disposed. The proximal end of the body may optionally form a finger grip. The medicine injection device further comprises a plunger locking mechanism attached to the proximal end of the body. The plunger locking mechanism comprises a member with an aperture slidably engaged with the plunger shaft. The locking mechanism is configured for preventing the plunger from being removed from the cartridge barrel. For example, the plunger shaft may include a locking stop, e.g., a flange, that engages with the aperture in an interference arrangement.

  • Patent number: 9895496
    Abstract: The present invention provides for an injection device including a syringe with a proximal end, a distal end, a needle extending from the distal end, and a plunger inserted into the 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 towards a second position wherein the guard covers the needle. The injection device includes first and second sets of cooperating detents for retaining the guard and syringe in the first and second positions, respectively. A latch member extends proximally from the guard that is engageable by the plunger as the plunger is depressed to release the first set of cooperating detents. Upon release, a spring element biases the guard towards the second position until the second set of cooperating detents engage and secure the guard in the second position.

  • Patent number: 9248242
    Abstract: 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.
