Patent number: 11176847Abstract: A training device for training a user on the operation of an auto-injector that dispenses a medicament. A needle guard is slidable from a first extended position relative to a housing prior to operation of the training device, to a retracted position during operation of the training device, and to a second extended position after operation of the training device. An actuation assembly controls the movement of the needle guard from the retracted position to the second extended position. A lock locks the needle guard in the second extended position. A safety is proximate a proximal end of the housing and prevents movement of the needle guard from the first extended position to the retracted position in a storage position. The needle guard is moveable into the retracted position with the safety in an armed position. The safety resets the lock upon returning the safety to the storage position.Type: GrantFiled: October 29, 2019Date of Patent: November 16, 2021Assignee: Antares Pharma, Inc.Inventors: Kevin D. Swanson, Julius Sund

Patent number: 11058824Abstract: A medicament dispensing mechanism is disclosed that is configured to eject successive doses of the medicament from a medicament chamber. An embodiment of the dispensing mechanism includes a housing and a plunger rod configured for ejecting the doses of medicament from the chamber. The dispensing mechanism further includes an actuation mechanism that comprises a trigger associated with the housing and having a ready and a fired position with respect thereto. The trigger is configured for manipulation by a user for successive movement in a generally axial dosing motion from the ready position to the fired position in which the trigger is associated with the plunger rod to cause the plunger rod to eject one of the doses of a predetermined volume and a resetting motion from the fired position to the ready position that comprises axial rotation, wherein the trigger is uncoupled from the plunger rod during the resetting motion.Type: GrantFiled: April 19, 2019Date of Patent: July 13, 2021Assignee: Antares Pharma, Inc.Inventors: Janice L.
