Publication number: 20230166046Abstract: A drive mechanism for a delivery device is presented containing, a rotator having an outer surface and an inner surface, the rotator configured to rotate from a first position to a second position. A needle cover having an inner surface that engages the outer surface of the rotator. A rotatable plunger rod having an outer surface configured to engage the inner surface of the rotator. When the rotator rotates from the first position to the second position, the rotatable plunger rod is rotated by the rotator and a plunger rod spring is released from a pre-tensioned state to exert a force on the rotatable plunger rod.Type: ApplicationFiled: January 11, 2023Publication date: June 1, 2023Inventors: Jason Frost, Slobodan Stefanov

Patent number: 11318259Abstract: A needle shield remover is presented having a generally tubular body with a longitudinal extension and a grip element composed of a braided sleeve arranged to the tubular body, where the braided sleeve has an opening of such a diameter that a needle shield may be introduced, where the diameter narrows such that a friction fit is created between the braided sleeve and the needle shield when said needle shield is pulled for removing the needle shield.Type: GrantFiled: April 23, 2018Date of Patent: May 3, 2022Assignee: SHL MEDICAL AGInventors: Brian Maxfield, Dane Kris, Jason Frost

Patent number: 11110230Abstract: A needle shield remover is presented having a generally tubular body with a longitudinal extension and a number of grip elements arranged at a distal area of the body, where the grip elements extend radially inwards from a circumference of the body. At least one longitudinally extending cut-out in the body and adjacent to the grip elements engage an outer surface of a needle shield when the needle shield remover is pushed onto the needle shield, where the at least one cut-out enables a generally radial outwardly bias of the grip elements during the pushing action to facilitate mounting of the needle shield remover on the needle shield.Type: GrantFiled: April 23, 2018Date of Patent: September 7, 2021Assignee: SHL MEDICAL AGInventors: Brian Maxfield, Jason Frost, Dane Kris

Publication number: 20210220565Abstract: A needle shield remover for assembly with a cap of a medicament delivery device is presented, having a remover body with a proximal end and a distal end, and at least one first shield gripping member, and at least one second shield gripping member, where the first shield gripping member and the second shield gripping member configured to engage the needle shield. The first shield gripping member and the second shield gripping member are arranged offset in relation to each other both in the longitudinal direction and along the circumference surface of the remover body.Type: ApplicationFiled: September 12, 2019Publication date: July 22, 2021Inventors: Jason Frost, Slobodan Stefanov

Patent number: 11065390Abstract: A drive mechanism for a delivery device comprising a rotator comprising an outer surface and an inner surface, the rotator configured to rotate from a first position to a second position; and a needle cover comprising an inner surface that engages the outer surface of the rotator. An end of injection indication device is positioned at least partially within a plunger rod spring, the end of injection indication device providing a signal to a user of the drive mechanism that an injection has been completed.Type: GrantFiled: January 20, 2017Date of Patent: July 20, 2021Assignee: SHL MEDICAL AGInventors: Jason Frost, Mattias Daniel, Sebastian Karlsson
