Patent number: 11053066Abstract: A syringe propellable by propellant that boils at a predetermined temperature, the syringe including a barrel having an outlet at a front end, and a stopper axially moveable in the barrel. The stopper separates a first chamber and a second chamber, the first chamber being axially forwards of the stopper and being configured for containing a medicament, and the second chamber being axially rearwards of the stopper and being configured to receive propellant for acting on the stopper to move the stopper axially forwardly in the barrel to expel medicament through the outlet upon actuation of the syringe. The syringe further includes a third chamber for containing propellant. Upon actuation of the syringe, liquid propellant is released from the third chamber and boils outside of the third chamber at or above the predetermined temperature to provide an increasing vapor pressure in the second chamber that causes the stopper to move axially forwardly and begin to expel medicament through the outlet.Type: GrantFiled: June 7, 2013Date of Patent: July 6, 2021Assignee: CONSORT MEDICAL LIMITEDInventors: Ian Anderson, Rachel Suzanne Koppelman, Alastair Mckean Willoughby, Douglas Jennings

Patent number: 9623183Abstract: An engine for an-auto injector for administering a dose of a liquid medicament includes a case arranged to be attached to a package syringe containing a syringe. The case contains a drive capable of, upon activation, pushing the needle from a covered position into an exposed position, and operating the syringe to supply the dose of medicament. The case contains a trigger arranged to lock the drive in a loaded state prior to manual operation and capable of, upon manual operation, releasing the drive for injections. The drive is arranged as a gas spring including a cylinder and a piston with a plunger for transmitting the spring force. A latch is arranged for preventing translating between the cylinder and the case. The latch is disengageable by the released gas spring being at least nearly fully extended thus allowing the extended gas spring to be translated in a distal direction.Type: GrantFiled: October 6, 2011Date of Patent: April 18, 2017Assignee: Sanofi-Aventis Deutschland GMBHInventors: Douglas Jennings, Thomas Kemp, Matthew Ekman

Patent number: 9233214Abstract: An injection device includes a syringe with a hollow needle and a stopper for sealing the syringe and displacing a medicament stored in the syringe. An arrangement for transferring a translation of a drive means to a plunger for pushing against the stopper includes a release latch pivoted at one end and connected to either the drive means or the plunger. The other end of the release latch engages the other one of the drive means or the plunger. The non-pivoted end of the release latch disengages by rotation upon contact between a ramp and another component when the stopper has displaced most of a predefined medicament dose. The release latch is long enough to provide a clearance between the plunger and the drive means when engaged to allow the plunger, stopper and needle to be retracted inside the syringe or a housing after disengaging the release latch.Type: GrantFiled: March 3, 2011Date of Patent: January 12, 2016Assignee: Sanofi-Aventis Deutschland GMBHInventors: Thomas Mark Kemp, Douglas Jennings, Andrew Peter Scudamore, Matthew Ekman

Patent number: 9180258Abstract: An auto-injector for administering a dose of a liquid medicament (M) is presented having an elongate housing arranged to contain a syringe, a proximal end (P) with an orifice, wherein the syringe is slidably arranged with respect to the housing. A drive spring upon activation pushes the needle from a covered position inside the housing into an advanced position through the orifice and past the proximal end (P), and operates the syringe to supply the dose of medicament (M). An activating means locks the drive spring in a compressed state. The housing distal and a proximal portions are connected by a hinge, and are rotatable about the hinge between an aligned position and a maximum opening angle. A loading bay for holding the syringe is arranged in the proximal portion.Type: GrantFiled: March 3, 2011Date of Patent: November 10, 2015Assignee: Sanofi-Aventis Deutschland GMBHInventors: Thomas Mark Kemp, Douglas Jennings, Andrew Peter Scudamore, Matthew Ekman

Patent number: 9155837Abstract: An auto-injector with an interlock mechanism for defining an operation sequence in a manner to allow a lateral trigger button to be operated when a proximal end of the auto-injector is pressed against an injection site. A detector is arranged inside an elongate housing of the auto-injector at the proximal end and slidable in longitudinal direction and biased by a detector spring. A dog is arranged at the trigger button and wherein at least one longitudinal bar is provided, at least one of the bars slidable in longitudinal direction and coupled to the detector for distal movement. A recess for the dog is provided in the bar for allowing the trigger button to be pressed when the detector means is being pushed into the auto-injector and wherein otherwise the dog is engaged with the bar in a manner to prevent the trigger button from being pressed.Type: GrantFiled: March 3, 2011Date of Patent: October 13, 2015Assignee: Sanofi-Aventis Deutschland GMBHInventors: Thomas Mark Kemp, Douglas Jennings, Peter Scudamore, Matthew Ekman
