    摘要： The bearing component comprises a contact surface inside a periphery, which surrounds a centre, and a coupling feature arranged inside the periphery for rotatably engaging a component of a piston rod perpendicular to the contact surface. The coupling feature includes at least one flexible feature extending from the periphery towards the centre, and the flexible feature is arranged to be deflected towards the periphery by a force exerted on the flexible feature in a direction towards the contact surface and deflected towards the centre by a force exerted on the flexible feature in the opposite direction. The flexible feature may have a sloping surface facilitating assembly and preventing disassembly in combination with a further component of the piston rod. The component of the piston rod may be a lead screw, and the piston rod may be used in a drug delivery device.

    摘要： An assembly for a drug delivery device is provided, the assembly having an actuator which is configured to perform a setting movement in a proximal direction in order to set a dose of a drug, and which is configured to perform a dispense movement in a distal direction in order to dispense a dose of a drug. The assembly further having a stop mechanism acting after a maximum amount of a drug has been delivered, which is configured to axially constrain the setting movement of the actuator such that the setting of a dose is inhibited, wherein a limited axial movement of the actuator is allowed.

    摘要： An injection device (1), the injection device comprising:
    a housing (10) containing a first optical sensor and a second optical sensor spaced circumferentially relative to a dialling sleeve of the injection device, wherein the optical sensors are arranged to detect optical features on a rotatable surface of the dialling sleeve, wherein the optical features comprise black and white regions, and wherein each optical sensor has a first state when it detects a white region and a second state when it detects a black region; and
    a processor arrangement configured to:
    detect a change in the state of each of the optical sensors; and
    determine a direction of rotation of the rotatable surface of the injection device from the detected state changes,

    wherein the rotatable surface of the dialling sleeve is arranged to move rotationally and axially with respect to the housing.
