Embodiment Construction

[0096] now go to figure 1 , the drug delivery device 1 includes a cartridge unit 2 and a drive unit 3 . The cartridge unit 2 comprises a cartridge 4 . Drug 5 is held in cartridge 4 . Drug 5 is preferably a liquid drug. The cartridge 4 preferably comprises a plurality of doses of medicament 5 . Drug 5 may for example comprise insulin such as short-acting or long-acting insulin, heparin or growth hormone. The cartridge 4 has an outlet 6 at its distal end. Drug 5 can be dispensed from the cartridge through outlet 6 . The device 1 may be a pen-type device, in particular a pen-type injector. Device 1 may be a disposable or reusable device. The device 1 may be a device configured for dispensing a fixed dose of medicament, or a variable dose, preferably user-settable dose. Device 1 may be a needled or needleless device. The device 1 may be an injection device.

Abstract

An assembly for a drug delivery device (1) is proposed, comprising: a housing (13) having a proximal end and a distal end; a dosing member displaceable relative to the housing in a proximal direction to set a dose of a drug ( 23); a clutch member (28) that displaces in a proximal direction relative to the housing when a dose is set; and a stop member (30) configured to limit the proximal displacement of the clutch member relative to the housing A clutch detent position in which the clutch member is prevented from further displacement relative to the housing in the proximal direction when in the clutch detent position, wherein the clutch member and the dose member are configured to be mechanically mechanical to each other when the clutch member is in the clutch detent position Cooperate to prevent further displacement of the dose member in the proximal direction relative to the housing during dose setting. Furthermore, a drug delivery device (1) is proposed.

Description

technical field [0001] The present disclosure relates to an assembly for a drug delivery device and a drug delivery device. Background technique [0002] Using the drug delivery device, the patient can self-administer the drug contained in the device. For this purpose, the user can set the dose of drug to be delivered, which is then delivered. Since the amount of drug present in the device may be limited, it may happen that the desired dose set by the user exceeds the amount of drug actually available in the device. Therefore, if the user administers the set dose, the user may mistakenly believe that the desired amount has been administered. Contents of the invention [0003] It is an object of the present disclosure to provide an assembly which helps to provide an improved drug delivery device and a drug delivery device comprising such an assembly. [0004] This object is achieved by an assembly according to the independent claims. Advantageous embodiments and develop...
