Publication number: 20210268192Abstract: A single-use auto-injector includes a housing and a dosing unit in at least part of the housing. The dosing unit includes a needle, a drug container with drug, a piston movable in the container, a first mechanical power supply for moving the piston to deliver the drug, an activation mechanism, and a mechanical escapement mechanism for controlling the movement of the piston. The auto-injector has a first state in which the needle is protected from needle damage or contamination, a second state in which the needle is ready to penetrate a human body, a third state in which the needle has penetrated the human body and is ready to dose, and a fourth state in which the needle is shielded to avoid unintended needle sticks. A second mechanical power supply is configured to shift state of the auto-injector from the third state to the fourth state.Type: ApplicationFiled: May 18, 2021Publication date: September 2, 2021Inventors: Hans Stenberg Knudsen, Christian Plambech, Rasmus Øhlenschlæger, Jørgen Jørgensen

Publication number: 20210260302Abstract: A drug delivery device includes a housing, an injection assembly at least partially disposed in the housing, a shield, and a drive assembly at least partially disposed in the housing and coupled with the injection assembly and the shield. The shield has an extended position where at least a proximal end thereof extends a distance beyond a proximal end of the housing. The injection assembly includes a needle or cannula having an endpoint. Upon moving the shield axially towards the distal end of the housing a predetermined distance, a retraction profile commences whereby the drive assembly administers a medicament via the injection assembly. A peak resistance force is exerted within approximately the first 12 mm of axial movement of the shield.Type: ApplicationFiled: August 16, 2019Publication date: August 26, 2021Inventors: Matias Melander, Joshua Jay Dudman, Joseph Michael Iglesias, Bjarke Lykke Ludvig Svendsen, Adam B.

Patent number: 11052185Abstract: The present invention concerns a medical injection device for apportioning set doses of a preservative containing liquid drug. The injection device comprises a housing supporting a cartridge containing the preservative containing liquid drug and a needle cannula for transferring the liquid drug from the cartridge and through the skin of a user. Further, a needle shield which is axially movable in relation to the housing is also present. The axially movable shield carries a cleaning reservoir for cleaning at least the tip of the needle cannula between subsequent injections and the cleaning reservoir is preferably filled with preservative containing liquid drug directly from the cartridge upon initiation of the injection device. In order to eliminate any overpressure being built up inside the cleaning reservoir during the filling process, the cleaning reservoir is provided with an outlet configured to be permanently sealed by a user activated operation.Type: GrantFiled: September 19, 2016Date of Patent: July 6, 2021Assignee: Novo Nordisk A/SInventors: Bjoern Gullak Larsen, Christian Plambech, Lars Eilertsen, Mattias Ingerslev, Ruben Archilla, Soeren Dyring Jensen
