Patent number: 10980947Abstract: Drive and dosing devices for injection devices are disclosed. An embodiment may include a threaded piston rod moveable in a dispensing direction for dispensing a product. A rotation member may be operatively connected to a stop limiter and threadably engaged with the piston rod. Rotation of the rotation member may cause the piston rod to move in the dispensing direction. An embodiment may include a dose knob rotatable for changing a dose. The device may further include a stop element threadably engaged with the piston rod and having a catch. The dose knob may be coupled with the stop element such that during increase of a dose, the stop element is screwed toward the distal end of the piston rod and the catch is moved towards the stop limiter. The stop element prevents increasing a dose when the catch abuts the stop limiter.Type: GrantFiled: October 22, 2018Date of Patent: April 20, 2021Assignee: Ypsomed AGInventors: Juerg Hirschel, Ursina Streit, Patrick Hostettler

Publication number: 20210038810Abstract: An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.Type: ApplicationFiled: October 23, 2020Publication date: February 11, 2021Inventors: Jürg Steck, Jan Baumert, Christoph Lauster, Thomas Gurtner, Réne Mathys, Patrick Hostettler, Nicolas Binggeli, Thomas Buri

Publication number: 20200316314Abstract: An insertion mechanism for a cannula includes a cannula housing, a displaceable cannula, at least one cannula holder, an insertion spring, a triggering element, and a safety device. The safety device, in a secured state, holds the triggering element in a blocked position against a force of the insertion spring and, in a released state, releases the triggering element such that the triggering element is movable into a release position by the force of said insertion energy store and the at least one cannula holder is able to move relative to the cannula housing, driven by the insertion energy store, so as to trigger or implement an insertion movement or insertion. To reach the released state, the safety mechanism is heatable by a heating element and softened and/or weakened with respect to its mechanical carrying or holding capacity, or severed or at least partially or completely melted.Type: ApplicationFiled: June 18, 2020Publication date: October 8, 2020Inventors: Thomas Buri, Christophe Hofer, Patrick Hostettler, Seline Staub, Jürg Steck, Ursina Streit

Publication number: 20200139052Abstract: 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: ApplicationFiled: January 6, 2020Publication date: May 7, 2020Inventors: Susanne Schenker, Ursina Streit, Patrick Hostettler

Publication number: 20190240417Abstract: A segmented piston rod for an injection device includes multiple segments joined together via a hinge located on one side of each segment. The piston rod can be bent in one direction by articulating subsequent hinges while an axial force can be transmitted by the segmented piston rod to the stopper when the subsequent hinges are closed and the segments abut each other opposite to the one side of the hinge. The segmented piston rod is secured against rotation relative to the housing around the longitudinal axis of the segmented piston rod. The segmented piston rod has a last element which abuts the stopper in the reservoir and a first segment which is opposite to the last segment. The first segment is includes an internal thread matching an external thread of a drive sleeve and rotation of the drive sleeve advances the piston rod towards the stopper of the reservoir.Type: ApplicationFiled: May 24, 2017Publication date: August 8, 2019Inventors: Patrick Hostettler, Jürg Hirschel, Simon Scheurer
