A drug delivery device with a housing configured to connect to a dispensing unit including a compartment containing a fluid, a piston rod configured to move in a proximal direction for ejecting the fluid, and a dosing mechanism including an actuation member to be actuated by a user. The device includes a conversion mechanism configured to convert a movement of the actuation member to a movement of the piston rod. The conversion mechanism includes a dose selector member, which is rotationally fixed to the housing and axially movable with respect to the housing, and a dosing member, which is rotationally movable with respect to the dose selector member. The drug delivery device includes a friction reduction mechanism provided between the dose selector member and the dosing member to reduce friction between the dose selector member and the dosing member.

Drug delivery device

An analysis device is provided comprising a housing having at least two housing parts, a measuring unit and a processor provided therein for purposes of the functionality of the analysis device and generation of analysis data, wherein the device comprises a lock element for producing a generally fixed mechanical connection between the at least two housing parts. Providing such a lock element allows the analysis device to be checked for quality control and/or functionality purposes before the lock element is fitted to the housing, and if the device requires service or repair as a result of such checks then the housing can be reopened without damage to the housing or other aspects of the device. Once the lock element is fitted into a locked position for locking the housing together, subsequent reopening of the housing causes structural effects, including damage or destruction, to either or both of the lock element and the housing or housing parts, ensuring that such reopening becomes apparent to the user.
