Abstract: A barrier cartridge for providing a sterility barrier between movable interfaces comprising a barrier with first and second ends; a barrier receiving portion, adapted to receive the barrier, and comprising first second ends spaced apart from one another, first and second sides spaced apart from one another and extending between the first and second ends, wherein the barrier is attachable to the barrier receiving portion such that it extends between the first and second sides of the barrier receiving portion and is movable between the first and second ends of the barrier receiving portion; first and second flex cards each operatively connected to both the respective end of the barrier and the respective end of the barrier receiving portion and extendible between the first and second sides of the barrier receiving portion.

Abstract: An injection device comprising a housing (112), and a dose selector (116) operatively connectable to a dose indicator positioned within the housing. The dose selector and the dose indicator (118, 119) are capable of cooperating to set a dose to be ejected from the injection device. The injection device further comprises a spring (120) capable of storing energy necessary for ejecting the dose from the injection device. The spring is locked to the dose indicator such that a charging force can be transferred from the dose selector to the spring via the dose indicator to increase the energy stored by the spring.

Abstract: An injection device comprising a housing (12) and a dose selector (16) to set a dose of medicament to be ejected from the injection device. A spring (20) coupled to the dose selector stores energy necessary for ejecting the dose from the injection device. A ratchet (25) arrangement is provided to rotationally couple a ratchet component and an internal surface of the housing in a coupled state and to allow relative rotation between the ratchet component and the internal surface of the housing in an uncoupled state. An over-torque feature (27) located between the dose selector and the spring is actuatable, when the rotation of the dose selector causes the charging force to exceed a defined limit, to reduce the charging force transferred from the dose selector to the spring. Both the ratchet component and the over-torque feature are provided on a single component (28).

Abstract: An injection device comprising a housing having a longitudinal axis, a dose selector (16) capable of being rotated about said longitudinal axis with respect to said housing by a user to set a dose of medicament to be ejected from the injection device and a spring (20) capable of storing energy necessary for ejecting the dose of medicament from the injection device. The spring is coupled to the dose selector such that a charging force can be transferred from the dose selector to the spring to increase the energy stored by the spring. The injection device further comprises a ratchet arrangement (25) moveable between an engaged state in which the spring is limited from unwinding from a currently selected dose and a disengaged state in which the spring is able to unwind and a drive assembly including a plunger element (23) capable of providing an axial force for ejecting a dose of medicament from the injection device.

Abstract: An injection device comprises a housing, a dose indicator positioned within the housing and a dose selector operatively connectable to the dose indicator. The dose selector and the dose indicator are capable of cooperating with one another to set a dose to be ejected from the injection device. The dose indicator comprises an odometer including: i. a units (218) wheel operatively connected to the dose selector so that rotation of the dose selector also rotates the units wheel, and ii. a tens wheel (219) selectively engageable with the units wheel so that rotation of the units wheel also rotates the tens wheel. The dose indicator further comprises an axially-moveable shuttle lock (222) rotationally locked to the tens wheel and selectively engageable with the units wheel and the housing. The tens wheel is selectively engageable with the units wheel via said shuttle lock and, when the tens wheel is not engaged with the units wheel, the shuttle lock is rotationally locked to the housing.
