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

Publication number: 20200268979Abstract: A piston rod unit for a device for administering a medical substance delays a release of a mechanism of the device and includes an outer piston rod with a hollow space and a contact face for interacting with a stopper to discharge the substance, and an inner piston rod mounted in the outer piston rod to form a cavity at the distal end of the outer piston rod. The cavity contains a viscous fluid and a fluid displacement element located at least partially in the cavity that is operably or integrally connected to the inner piston rod. During relative movement between the fluid displacement element and the outer piston rod, fluid displacement causes movement resistance, such that mechanism release is delayed. The outer piston rod includes a distal, first piston rod part, comprising the contact face and the cavity, and a second piston rod part adjoining the first.Type: ApplicationFiled: May 13, 2020Publication date: August 27, 2020Inventors: Marc Fiechter, Stefan Burren, Markus Tschirren, Markus Hunziker
