Publication number: 20200316298Abstract: According to the invention, an auto-injector for administering a dose of a liquid medicament (M) comprises of a substantially cylindrical housing arranged to contain a pre-filled syringe filled with the medicament (M), a needle shroud slibably arranged with respect to the housing and adapted to rest on the skin of a patient receiving an injection, a releasable drive means arranged within the housing that is capable of, upon release, translating the needle shroud in a proximal direction (P) towards a safe position (PS) and a rotating collar rotatably arranged within the housing. The needle shroud in the safe position (PS) surrounds the injection needle after the injection has been carried out. The rotating collar engages the needle shroud in a manner that forces the rotating collar to rotate within the housing when the needle shroud is translated in the proximal direction (P).Type: ApplicationFiled: June 23, 2020Publication date: October 8, 2020Inventors: Yannick Hourmand, Timothy Donald Barrow-Williams, Matthew Ekman

AUTOINJECTOR WITH AN INNER PLUNGER WHICH DISENGAGES THE OUTER PLUNGER TO RETRACT THE SYRINGE CARRIER
Publication number: 20200261661Abstract: Described is an autoinjector comprising a case, a chassis slidably arranged in the case, a syringe carrier operably coupled to the chassis, an outer plunger selectively engaged to the chassis, an inner plunger selectively engaged to the outer plunger, and a drive spring applying a biasing force to the outer plunger. The biasing force is applied to the inner plunger when the inner plunger is engaged to the outer plunger. Rotation of the chassis causes the inner plunger to rotate relative to the outer plunger and disengage the outer plunger to remove the biasing force from the drive spring on the inner plunger. When the inner plunger disengages the outer plunger, the biasing force of the drive spring pushes the chassis to retract the syringe carrier relative to the case.Type: ApplicationFiled: April 14, 2020Publication date: August 20, 2020Inventors: Yannick Hourmand, Simon Brereton, Thomas Mark Kemp, Rosie Burnell, Matthew Ekman -

Publication number: 20200197610Abstract: Auto-injector for administering a dose of a liquid medicament includes a housing to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, the housing having a distal end and a proximal end with an orifice to apply against an injection site. A spring means, upon activation, can push the needle from inside the housing through the orifice and past the proximal end, operate the syringe to supply the dose of medicament, and retract the syringe with the needle after delivering the medicament. An activating means can lock the spring means in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means for injection.Type: ApplicationFiled: March 5, 2020Publication date: June 25, 2020Inventors: Matthew Ekman, Yannick Hourmand, Timothy Donald Barrow-Williams

Patent number: RE47903Abstract: An auto-injector for administering a dose of a liquid medicament (M) comprises of a substantially cylindrical housing arranged to contain a pre-filled syringe with an injection needle, a plunger and a stopper for sealing a syringe barrel and a drive means releasably coupled to the plunger for advancing the syringe in the proximal direction (P) for needle insertion into an injection site and for displacing the dose of medicament (M) into the injection site. The drive means is arranged to be decoupled from the plunger for advancing a needle shroud to a safe position (PS) to surround the injection needle after the injection. According to the invention, the drive means bears against a thrust collar arranged to be releasably coupled to the plunger through a ramped engagement of a first tongue and a first recess so as to rotate the thrust collar on translation in proximal direction (P).Type: GrantFiled: February 26, 2018Date of Patent: March 17, 2020Assignee: Sanofi-Aventis Deutschland GMBHInventors: Yannick Hourmand, Simon Francis Brereton, Matthew Ekman
