Drive Mechanisms Suitable for Use in Drug Delivery Devices

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.

Drive mechanism of a drug delivery device

A drive mechanism of a drug delivery device for setting and dispensing of a dose of a medicament includes a housing, a piston rod, a dose indicating member with a dose size information thereon, and a drive wheel. The piston rod engages with a piston of a cartridge for displacing the piston in a distal direction. The dose indicating member is connected to a spring element and is rotatable in a dose incrementing direction against the action of the spring element for setting a dose. The drive wheel is operably engaged with the piston rod for displacing the piston rod in the distal direction for dose dispensing. The dose indicating member is engageable with the drive wheel during dose dispensing to transfer a force to the drive wheel when driven by the relaxing spring element in a dose decrementing direction.
