Embodiment Construction

[0025] Below, refer to figure 1 The shown drug delivery device similar to the device disclosed in EP1603611B1 describes the features of the present invention.

[0026] Although the invention is described with reference to this particular drug delivery device, the dose setting mechanism may be applied to other variable dose injection devices which limit the maximum dose in a similar manner. In other words, it is equally applicable to any drug delivery device where the maximum dose stop is determined by the characteristics of two separate parts that move towards each other and come into contact when the maximum dose is reached. This can be applied to components that move in rotation, such as in dialable variable dose pens, or to components that travel axially, such as in push-pull fixed dose pens. Furthermore, although the invention is described with reference to a disposable drug delivery device, the invention is also applicable to reusable drug delivery devices.

Abstract

A dose setting mechanism for a drug delivery device is provided comprising a dose setting member and a further element. Maximum dose stop features are provided on a housing and on the further element.

Description

technical field [0001] The present invention relates to a dose setting mechanism for a drug delivery device, such as a pen-type injector, which enables administration by injection of medicament from a multi-dose cartridge. Background technique [0002] EP1603611B1 discloses a syringe in which the user can set the dose. The main components of a drug delivery device and its drive mechanism are disclosed in EP1603611B1, to which reference is made in more detail below. The application of this syringe is: daily injections by people without formal medical training. This is an increasing prevalence among those with diabetes, and self-treatment enables these individuals to manage their diabetes effectively. These circumstances place many demands on such pen-type injectors. [0003] The syringe must be robust in construction yet easy to use in terms of handling of the components and understanding of its operation by the user. With diabetes, many users are debilitated and may also...
