Publication number: 20230021831Abstract: An autoinjector includes a housing, a product container, a torsion spring, a drive element, and a propulsion element. In order to discharge liquid out of the product container, the torsion spring rotates the drive element, and the rotating drive element produces a propulsive movement of the propulsion element and of a piston in the product container. A rotation sensor is configured for an alternating continuous detection of at least two rotational positions per revolution of the drive element during the discharge process, and a processor unit is configured for determining the axial position of the piston in the product container from the detected rotational positions.Type: ApplicationFiled: September 26, 2022Publication date: January 26, 2023Inventors: Gabriel Kalbermatter, Leos Urbanek, Markus Tschirren, Jürg Hirschel, Martin Brügger

Patent number: 11541189Abstract: This relates to an injection device comprising a housing for receiving a product container, which has a rigidly connected injection needle, and a cap for removing a needle protection cap from the product container. The cap comprises an engagement element in order to carry out the removal of the needle protection cap from the product container while removing the cap from the injection device. The cap further comprises a rotating sleeve, wherein the rotating sleeve has a reverse rotation protection element, and the engagement element or the housing has a reverse rotation protection counter-element in order to allow a rotation of the rotating sleeve in one direction and block the rotation in the opposite direction.Type: GrantFiled: June 19, 2020Date of Patent: January 3, 2023Assignee: Ypsomed AGInventors: Stefan Burren, Jürg Hirschel, Markus Tschirren, Andres Mellenberger

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

Publication number: 20210353862Abstract: Modular syringe holders receive small-volume product containers for use in injection devices configured for nominally large-volume product containers, and include an adapter and an adapter holder configured for insertion in such injection devices. The adapter includes a hollow-cylindrical, rigid adapter body and a radially deflectable support element for a receiving a syringe shoulder of a pre-filled syringe. During receipt of the pre-filled syringe, the support element undergoes a radial deflection by a needle protection cap of the pre-filled syringe. The adapter holder is configured to receive the adapter, and a holding portion of the adapter holder blocks the support element against radial deflection in a holding position in an engagement with the syringe shoulder. With the adapter and pre-filled syringe received in the adapter holder, a flexible shoulder-support element diverts axial forces of the shoulder of the pre-filled syringe and is secured by the adapter holder against lateral deflection.Type: ApplicationFiled: July 29, 2021Publication date: November 18, 2021Inventors: Christian Schrul, Markus Tschirren

Publication number: 20210154407Abstract: An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.Type: ApplicationFiled: November 25, 2020Publication date: May 27, 2021Inventors: Jürg Hirschel, Markus Tschirren, Ulrich Moser, Ursina Streit
