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 -

Patent number: 10668225Abstract: According to the invention a safety device for a pre-filled syringe comprises a substantially cylindrical and hollow support body and a hollow needle shield slideably arranged relative to the support body. The support body comprises at least one resilient arm and the hollow needle shield or a needle shield assembly comprises at least one curved actuation ramp. The curved actuation ramp protrudes in a lateral direction (L) perpendicular to a central axis (A) of the safety device. The curved actuation ramp comprises a first lateral dimension (L1) at a proximal end of the needle shield and a second lateral dimension (L2) exceeding the first lateral dimension (L1) at a distal end of the needle shield. The resilient arm engages the curved actuation ramp when the needle shield is slid relative to the support body.Type: GrantFiled: May 7, 2018Date of Patent: June 2, 2020Assignee: Sanofi-Aventis Deutschland GMBHInventors: Gareth Roberts, Chris Ward, Matthew Ekman

Patent number: RE48593Abstract: 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: January 28, 2020Date of Patent: June 15, 2021Assignee: Sanofi-Aventis Deutschland GMBHInventors: Yannick Hourmand, Simon Francis Brereton, Matthew Ekman
