Patent number: 11260176Abstract: An autoinjector (100?) for expelling a single dose of a drug from a held cartridge (600) comprising a piston (630). The autoinjector includes a needle shield (350, 380?) axially movable from an initial extended position via a triggering position to a trigger release position. The needle shield (350, 380?) is operatively coupled to a plunger release element (320?, 1320) cooperating with a plunger (310, 400) to define a releasable retaining mechanism that retains the plunger release element (320?, 1320) threadedly engaged with a base thread component (204?, 1204) in a predefined relative rotational and axial position and against rotational bias provided by an actuator (330). The needle shield (350, 380?) is configured for operating the retaining mechanism to release the retaining of the plunger release element (320?, 1320) and the base thread component (204?, 1204) from the predefined relative rotational and axial position upon the needle shield (350, 380?) being moved into the trigger release position.Type: GrantFiled: December 29, 2016Date of Patent: March 1, 2022Assignee: Novo Nordisk A/SInventor: Soeren Kjellerup Hansen

Patent number: 10543322Abstract: An injection needle assembly (50) for an injection device, having a) a needle cannula (3) attached to a needle hub (4) and defining a pointed tip at a free end (3a, 3b), and b) a needle cover (10, 10a, 10b) forming an axially extending elongated flexible enclosure accommodating the needle cannula (3). The needle cover (10, 10a, 10b) is configured to axially collapse and become penetrated by the needle cannula (3) when a penetration force is applied to the needle cover. The needle cover (10, 10a, 10b) defines a shaft section (11a) and a bulb section (11b). The shaft section (11a) encircles the needle cannula (3) and extends axially from the needle hub (4) to the bulb section (11b). The shaft section (11a) comprises a collapsible wall area (15) having wall thickness t1 less than a predefined wall thickness t1,lim to provide radial deformability for abutting contact with the needle cannula (3).Type: GrantFiled: January 22, 2016Date of Patent: January 28, 2020Assignee: Novo Nordisk A/SInventors: Modesto Javier Mora Benito, Soeren Kjellerup Hansen, Helle Ravn Thomsen, Daniel Patrick Godskesen True

Patent number: 10179212Abstract: An injection device for expelling a dose of drug from a held cartridge (600) is described. A needle shield (350, 380) is axially movable relative to a base (200, 220, 230) between a proximal collapsed position and a distal extended position. A needle shield lock comprises a deflectable lock element (392) operable to prevent the needle shield (350, 380) from being moved towards the proximal collapsed position. A lock activator (402) associated with a plunger (310, 400) exerts an activation force on the deflectable lock element when the plunger assumes a final position. A biasing means (403) is arranged to act between the lock activator (402) and the deflectable lock element (392), the biasing means (403) being configured to resiliency transfer the activation force from the lock activator (402) to the deflectable lock element (392) to enable the needle shield (350, 380) to become locked in the distal extended position but only when the plunger (310, 400) assumes the final position.Type: GrantFiled: June 26, 2015Date of Patent: January 15, 2019Assignee: Novo Nordisk A/SInventors: Mads Schenstroem Stefansen, Soeren Kjellerup Hansen, Bastian Gaardsvig Kjeldsen

Publication number: 20170143902Abstract: An autoinjector (100) for expelling a dose of a drug from a held cartridge (600) is described. A needle shield (350, 380) is axially movable relative to a base (200, 220) between an extended position and a collapsed position to operate a trigger lock (328, 388) configured for releasably maintaining a plunger (310, 400) in an initial axial position against the force of an actuator (330). One of the needle shield (350, 380) and the base (200, 220) defines one or more contact surfaces (382) each being resiliently slideable over a respective cooperating ramp surface (212) formed in the other of the needle shield (350, 380) and the base (200, 220) to provide a resistance to movement of the needle shield (350, 380) during needle shield displacement from the extended position towards the collapsed position. A high resistance to movement is obtained in a first stage of said needle shield displacement followed by a low resistance to movement in a second stage.Type: ApplicationFiled: June 26, 2015Publication date: May 25, 2017Inventors: Soeren Kjellerup Hansen, Mads Schenstroem Stefansen
