Patent number: 11524118Abstract: A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.Type: GrantFiled: January 6, 2020Date of Patent: December 13, 2022Assignee: Ypsomed AGInventors: Susanne Schenker, Ursina Streit, Patrick Hostettler

Publication number: 20220362458Abstract: Needle insertion mechanisms include a housing and a needle holder, the needle holder being linearly guided by the housing to be moved along the needle-axis. A slider linearly guided by the housing and transversally moveable with respect to the needle-axis from a first to a second slider position. The needle holder is operatively coupled to the slider when the slider is in the first position, thereby retaining the needle holder in a retracted position against the bias of a spring acting on the needle holder. In the second position the slider is decoupled from the needle holder and the holder is moved into an inserted position by the spring. A blocking member arranged between the slider and the housing blocking movement of the slider into the second position, is moved by an active drive thereby unblocking the movement of the slider and subsequently moving the slider to the second position.Type: ApplicationFiled: August 1, 2022Publication date: November 17, 2022Inventors: Christian Schrul, Stefan Burren, Mario Bernhard, Andres Mellenberger, Markus Tschirren, Michael Dobler, Marc Fiechter, Susanne Schenker

Publication number: 20220241497Abstract: An assembly for a cartridge needle insertion mechanism includes a housing, a cartridge needle defining a cartridge needle axis and a cartridge closed by a septum. A cartridge needle slider is linearly guided by the housing along an insertion axis to be moved by a driver from a first position, where the cartridge needle is not penetrating the septum, to a second position where the cartridge needle penetrates the septum of the cartridge. A cartridge needle holder holding the cartridge needle is operatively coupled with the cartridge needle slider to be moved with the cartridge needle slider from the first to the second position. The assembly includes a compliant coupling between the cartridge needle holder and the cartridge needle slider configured to facilitate movement of the cartridge needle holder with respect to the slider when moved into the second position, thereby compensating for needle penetration forces.Type: ApplicationFiled: April 19, 2022Publication date: August 4, 2022Inventors: Stefan Burren, Mario Bernhard, Andres Mellenberger, Markus Tschirren, Susanne Schenker, Christian Schrul
