Embodiment Construction

[0044] When terms such as "upper" and "lower", "right" and "left", "horizontal" and "vertical" or similar relative expressions are used below, these refer to the drawings rather than actual usage. The shown figures are schematic representations, therefore the configuration of the different structures as well as their relative dimensions are for illustrative purposes only.

[0045] An exemplary embodiment of the invention is implemented as an electronically controlled motorized drug delivery device adapted to receive a drug-filled cartridge comprising an outlet and an axially movable piston, the device comprising: a housing body; a compartment adapted to receive and hold a cartridge; an electronically controlled expulsion assembly comprising an axially movable piston drive member adapted to engage a piston of a loaded cartridge; a controller coupled to an ejection assembly configured to control the ejection assembly to move the piston in a distal direction to expel the drug from ...

Abstract

Method for detecting an end-of-dose condition in a pressurized system, comprising the steps of (a) providing a system having a fluid-filled variable volume reservoir comprising an elastically deformable portion and an outlet, pressurizing means, and means for detecting a property of the elastically deformable portion which varies with the internal pressure in the reservoir, (b) pressurizing the reservoir to expel a desired amount of fluid by applying a force, thereby deforming the elastically deformable portion, (c) measuring, after the actuating step, a property related to the elastically deformable portion as it regains its initial configuration, (d) comparing a value for the measured property with one or more threshold values, and (e) providing a user with an indication when a given threshold value has been reached, and / or when a given threshold value has not been reached within a given period of time.

Description

[0001] The present invention generally relates to a drug delivery device adapted to receive a drug-filled cartridge and expel a dose therefrom. More specifically, the present invention relates to the problem of notifying the user of user-related events after the detection of an end-of-dose state. Background technique [0002] In the disclosure of the present invention, the treatment of diabetes is mainly concerned, however, this is only an exemplary use of the present invention. [0003] Most common types of durable drug delivery devices adapted to receive a drug-filled cartridge comprising an initial Type of axially movable piston in the proximal position. The device may be pen-shaped, or in the form of a more box-shaped so-called applicator. In order to improve convenience, user friendliness and provide additional features such as detection and storage of expulsion data, drug delivery devices have been provided with electrically driven means, generally in the form of elect...
