Patent number: 10653841Abstract: A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.Type: GrantFiled: July 31, 2019Date of Patent: May 19, 2020Assignee: Sanofi-Aventis Deutschland GMBHInventors: Robert Frederick Veasey, Robert Perkins, David Aubrey Plumptre

Patent number: 10610650Abstract: An injection device includes a housing for receiving a syringe or cartridge for containing a medicament; a rotary driveshaft mounted for rotation relative to the housing; and an elongate coiled torsion spring having respective formations at opposite ends thereof, with a first formation being anchored in a seat on the rotary drive shaft and a second formation being anchored in a seat on a reaction component. In use relative rotation of the rotary driveshaft and the reaction component in one angular direction strains the torsion drive spring, and release of the strained torsion drive spring causes expression of medicament from the syringe or cartridge. The torsion spring is longitudinally resiliently compressible between its end formations whereby during assembly of the injection device, the torsion spring may be longitudinally compressed and then rotated, thereby urging the end formations of the torsion drive spring into engagement with the respective seats.Type: GrantFiled: June 1, 2017Date of Patent: April 7, 2020Assignee: OWEN MUMFORD LIMITEDInventors: Toby Cowe, Simon Reitter

Patent number: 10398840Abstract: A dispensing device which disperses medicate through a needle across a zone within a body. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a reservoir in fluid communication with the needle, positioned within the housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with the reservoir-connecting conduit, and a linear drive attached to the needle or to the needle-receiving member.
