Embodiment Construction

[0025] In this application, when the term "distal end / end" is used, it is meant the part / end of a drug delivery device or a component thereof which is positioned furthest away from the delivery location of the patient when the drug delivery device is in use. Accordingly, when the term "proximal portion / proximal end" is used, it is meant that part / end of the drug delivery device or a component thereof which is positioned closest to the delivery site of the patient in the case of use of the drug delivery device.

[0026] The dose setting mechanism according to the present invention shown in the accompanying drawings comprises:

[0027] - an elongated tubular distal housing 16 with opposite distal and proximal ends, wherein said distal housing comprises threads 14 on its inner surface, a first window 30, a second window 32 and a at least one opening 38 in the elongated surface;

[0028] - a tubular dose limiting member 10 having opposite distal and proximal ends, wherein said do...

Abstract

A dose setting mechanism for a medicament delivery device includes a tubular housing having threads on its inner surface, a first window, a second window, and at least one surface opening; a tubular dose limiting member having a first thread segment on its outer circumference for the threads on the housing's inner surface, first indicia on its outer circumference, a stop surface, and equidistant protrusions on its outer circumference; a tubular dose setting member; and a removable lock member attached to the housing. The housing is coaxially arranged inside the dose limiting member and includes a second thread segment for the housing's threads, second indicia, and a dose setting knob protruding through the housing. The lock member includes at least one elongated rib on its inner circumferential surface for interacting with the protrusions for locking the dose limiting member in position when the lock member is attached to the housing.

Description

technical field [0001] The present invention relates to a dose setting mechanism for a medicament delivery device. Background technique [0002] There are many devices for drug delivery that have been developed for self-use, ie a patient or other non-medically trained person handles the device during drug delivery. Such devices include inhalers, nebulizers and syringes. For many treatments, such as asthma, diabetes, hormone growth, the patient must receive regular doses, and the advantage of using this device is that the patient can get the medicine anywhere and does not have to visit a healthcare facility to receive the medicine. [0003] Self-administration devices need to be both reliable and easy to use for untrained users. It is therefore necessary to minimize the risk of mishandling the device so that the user does not receive the wrong dose size. [0004] WO 01 / 72361 A1 discloses an increment mechanism comprising presetting means configured to limit the settable do...
