Publication number: 20150126905Abstract: A safety sleeve system for syringes and other needle-based devices prevents accidental needle sticks after use of the syringe. The safety sleeve system allows an easy mechanical cover that, once actuated, locks over the exposed needle for safe coverage and disposal, or, in a sterile situation, allows for exposure of a clean needle. The safety sleeve system minimally alters an existing syringe and allows for identical use and function, with only an outer sleeve cover that follows tracks embossed on the exterior of the existing syringe. This sleeve cover can be twisted and locked in an operation position, where the needle extends from the sleeve cover, or in a safety position, where the needle is encased by the sleeve cover.Type: ApplicationFiled: November 7, 2013Publication date: May 7, 2015Inventor: Suzanne Lee Lowry

Patent number: 9022989Abstract: An injection device has a main drive module which can be screwed into the back of a syringe housing to prepare the injector ready for use. The drive module has a firing button and a drive plunger released for forward movement by pressing the firing button. The syringe housing slideably receives a syringe holder whose forward movement is initially prevented by internally directed barbs on a cylindrical latching sleeve. The latching sleeve is acted upon by a release ring on the drive module such that as the drive module is screwed onto the syringe housing, the release ring splays the cylindrical shell to release the syringe carrier for forward movement. The barbs also act as a latch to capture the syringe carrier in its rearward position when the drive module is unscrewed from the syringe housing, which returns the barbs to their initial position before the syringe holder returns to its initial position.Type: GrantFiled: August 11, 2008Date of Patent: May 5, 2015Assignee: Owen Mumford LimitedInventors: Stephen Bicknell, Mark Eaton

Publication number: 20130331794Abstract: According to the invention, a safety device for a pre-filled syringe comprises a hollow support body to retain the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a guide pin, a guide track and a cut-out adjacent to the guide track. The guide pin protrudes into the guide track and moves within and along the guide track when the needle shield is slid relative to the support body. The cut-out allows a side wall of the guide track to be deflected in a lateral direction perpendicular to a central axis of the safety device.Type: ApplicationFiled: June 21, 2011Publication date: December 12, 2013Applicant: SANOFI-AVENTIS DEUTSCHLAND GMBHInventors: Matthew Ekman, Christopher James Smith, Troy Baker, Graham Wilson, Gareth Roberts, John Slemmen

Publication number: 20130331795Abstract: A safety device for a pre-filled syringe is proposed that comprises a hollow support body with a helical groove formed into an inner surface thereof, a mounting collar for mounting the pre-filled syringe to the support body, a spinning collar with a helical tongue formed to an outer surface thereof and a torsion spring. The helical groove accommodates the helical tongue. Upon release, the torsion spring is capable of exerting a torque upon the spinning collar which causes the spinning collar to rotate within the support body. The engagement of the helical groove and the helical tongue redirects the rotational movement of the spinning collar to a translatory movement that moves the mounting collar in a proximal direction.Type: ApplicationFiled: December 30, 2011Publication date: December 12, 2013Applicant: SANOFI-AVENTIS DEUTSCHLAND GMBHInventors: Gareth Roberts, Matthew Ekman

Publication number: 20130324923Abstract: According to the invention, a safety device for a pre-filled syringe comprises a hollow support body for mounting the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a flexible arm with a guide pin, a guide track and a separating wall. The guide pin extends from the flexible arm in a radial direction, and protrudes into the guide track. The separating wall extends into the guide track in a direction parallel to a central axis of the safety device. When the needle shield is slid relative to the support body the guide pin moves along the guide track to deflect the flexible arm in a lateral direction perpendicular to the central axis and the movement of the guide pin along the guide track is guided by the interplay of the flexible arm and the separating wall.Type: ApplicationFiled: June 21, 2011Publication date: December 5, 2013Applicant: Sanofi-Aventis Deutschland GmbHInventors: Gareth Roberts, Chris Ward, Matthew Ekman
