Patent number: 10765809Abstract: A reloadable auto injector has a needle insertion driver to be re-activated upon reloading. A syringe is movably positioned in a housing between a first position and a second position. A plunger rod is locked to a plunger rod tube by a deflectable locking member. A syringe driver applies a force to the syringe to move the syringe together with plunger rod tube, plunger rod and plunger rod driver from the first position to the second position. In the second position, the locking member is unlocked and releases the plunger rod to thereby activate the plunger rod driver to advance the plunger rod in the syringe for delivering of medicament. A reload handle is connected to the syringe assembly so that user operation of the reload handle retracts the syringe to the first position and simultaneously reloads the syringe driver for delivering a further dose of medicament.Type: GrantFiled: June 14, 2017Date of Patent: September 8, 2020Assignee: MERCK PATENT GMBHInventors: Soeren Bechmann, Flemming Madsen, Esben Johansen
