Embodiment Construction

[0042] refer to figure 1 , according to an exemplary pen-shaped design arrangement, here a drug delivery device 100 is shown. The drug delivery device 100 includes a housing having a first cartridge retaining portion 102 and a dose setting mechanism 104 . as about figure 2 It will be explained that the dose setting mechanism 104 may comprise multi-component parts such as a piston rod, a dose dial sleeve, a drive sleeve and a clutch. These various component parts may be assembled in a dose setting mechanism outer housing or housing 108 . The overall structure and function of the pen-type injection device 100, in particular the interaction of the drive sleeve, clutch member, dose dial sleeve, housing and piston rod during dose setting and dose delivery is described in detail in WO2004 / 078239A1 description, which is incorporated herein by reference.

[0043]The drug delivery device 100 may be a resettable drug delivery device (ie, a reusable device) or alternatively a non-re...

Abstract

A dose setting mechanism (200) comprises a drug delivery device housing (250) and a dual state track (262) provided within the housing that is axially and rotationally fixed with respect to the housing. A dose dial component (204) is positioned in the housing and rotatable during dose setting and dose delivery. A clutch (208) is rotatable during dose setting and non-rotatable during dose delivery. A clutch plate (212) is rotationally fixed relative to the housing; and a clutch blocker (220) is in threaded engagement with the clutch plate and has a radial key (222) engaged with the dual state track. The mechanism may comprise a biasing member (216) positioned between the clutch blocker and clutch plate.

Description

technical field [0001] This patent application is generally directed to a dose setting mechanism for a medicament delivery device, which controls the minimum and / or maximum possible dose setting and to a method of setting and delivering a dose, preferably using the medicament delivery device, which controls the minimum and / or the highest possible dose setting. More particularly, this patent application is generally directed to drug delivery devices, such as pen-type drug delivery devices, where therapy requires the patient to receive at least a certain minimum dose and not exceed a certain maximum dose of a particular drug. The device provides self-administration of a pharmaceutical product from a multi-dose cartridge and includes a dose limiting mechanism for setting minimum and / or maximum doses. The present application can be used on both disposable and reusable types of drug delivery devices. However, aspects of the invention are equally applicable in other contemplations...
