Embodiment Construction

[0051] figure 1 The injection device shown comprises a drive unit, which is preferably reusable, and a product container 27 connected to the drive unit and housed in a sleeve-shaped product container holder 16, which is for example reusable and which can be reusable by means of the product container. The bracket 16 is fastened to the drive unit. Once the product container 27 has been emptied, it can be removed from the injection device, thrown away and replaced with a new product container. The housing 12 is formed from several parts, since this makes manufacture and assembly easier, including the elements 12a, 12b connected or inserted therewith, wherein the housing can in principle also be formed in one part. The product container 27 is fastened to the drive unit by means of detents formed by the housing 12 , the product container bracket 16 and the sleeve 50 . The product container holder 16 is covered by a cap 31 attached to the housing 12 and can be removed for use with...

Abstract

The invention relates to an injection device comprising: a) a dose setting element (9; 10; 7; 4) and a first element (13) coupled thereto, which first element can be rotated relative to another second element (2; 5; 100) during a dose setting and is rotationally fixed relative to the second element (2; 5; 100) during a dose discharge, wherein the first element (13) and the second element (2; 5; 100) are coupled by means of a coupling element (30), and b) a stop (7b; 100a), wherein the coupling element (30) moves to a stop position during a dose setting, wherein the coupling element (30) in the stop position prevents the setting of a dose.

Description

technical field [0001] The invention relates to a mechanism for an injection device that prevents a dose being set beyond the amount of product to be administered in a product container of the injection device. The product to be administered may eg be liquid medicine, especially insulin. Background technique [0002] Dosing mechanisms for injection devices are known in the prior art which prevent doses from being set beyond the amount of medicament in the reservoir of the injection device. Such devices generally have the problem that they take up a considerable amount of space in injection devices, however the market demands manageable injection devices. [0003] Using injection devices known in the art, a dose can be set using the dose setting mechanism and then delivered from the product container. It may happen that a larger dose has been set with the dose setting element than can be delivered from the product container, eg because the product container contains less do...
