Patent number: 11458257Abstract: An injection device having a delivery element with an inner thread may be driven by rotation and includes a cylindrical outer wall region, which is substantially smooth. Such features provide a delivery element configured such that it is less intimidating to patients than known threaded rods, and may facilitate easy cleaning. The delivery element may be non-rotatably guided and axially spring-loaded, and may be inserted axially into the housing when the reservoir is replaced. The driving thread element for the delivery element may be mounted in the vicinity of the distal end of the housing.Type: GrantFiled: April 22, 2019Date of Patent: October 4, 2022Assignee: Ypsomed AGInventors: Philippe Kohlbrenner, Peter Stettler, Patrick Hostettler, Juergen Wittmann, Martin Wittwer
