Embodiment Construction

[0044] refer to figure 1 , figure 1 Shown is a drug delivery device 1 configured according to an exemplary pen-type design. The drug delivery device 1 comprises a housing with a first cartridge holder 2 and a dose setting mechanism 4 . The drug delivery device may be a resettable drug delivery device (ie, a reusable device), or alternatively, may be a non-resettable drug delivery device (ie, a non-reusable device). The first end of the cartridge holding portion 2 and the second end of the dose setting mechanism 4 are secured together by a connecting feature. For non-resettable devices, these connection features will be permanent and irreversible. For resettable devices, these connection features will be releasable.

[0045] In the configuration shown here, the cartridge holder 2 is secured within the second end of the dose setting mechanism 4 . A removable cap (not shown) is releasably retained over the distal or second end of the cartridge housing or cartridge retaining ...

Abstract

The present invention relates to a dose setting mechanism for a drug delivery device and a method of using same. The mechanism comprises a drug delivery device housing (205), a dose dial component (104) positioned in the housing (205) and rotatable during dose setting and dose delivery, a clutch (105) rotatable during dose setting and non-rotatable during dose delivery having, preferably located at a distal end, clutch teeth (109), and a clutch ring (102) engaged with the housing (205) in a first rotatable configuration and in a second non-rotatable configuration.

Description

technical field [0001] The present patent application is generally directed to a dose setting mechanism for a drug delivery device that controls the minimum and / or maximum possible dose setting, and to methods of using the dose setting mechanism, such as This is achieved by setting and / or delivering at least a predetermined minimum dose of the medicament. More specifically, the present patent application is generally directed to drug delivery devices, such as pen-type drug delivery devices, where the therapy requires the patient to receive at least a certain minimum dose and not exceed a certain maximum dose of a particular medicament. Such devices provide for self-administration of pharmaceutical product from a multi-dose cartridge and accommodate a dose limiting mechanism for setting minimum and / or maximum doses. The present application is applicable to both disposable and reusable drug delivery devices. However, aspects of the invention are equally applicable in other con...
