Indication mechanism for an automatic applicator, particularly for insulin
First Claim
1. An indication mechanism for an automatic applicator, particularly for insulin or other liquid preparations, particularly for multiple injection administration of set doses of a medicine from an exchangeable container, comprising:
- an applicator housing;
an assembly of at least two barrels arranged in the applicator housing and movably coupled to each other, wherein one barrel is an indication barrel mounted on the other barrel, the other barrel being a driving barrel, directly inside the applicator housing, the indication barrel containing a dose scale on an external surface, characterised in that the indication barrel containing the dose scale on its external surface is mounted slidingly, co-axially and lengthwise in the applicator housing, by a splined coupling, directly on an external surface of the driving barrel, without touching an internal side of the applicator housing, and the indication barrel, at a distal ending being co-axially and directly coupled to a separate pull-push control nut, the pull-push control nut being mounted rotatably on the driving barrel coaxially and lengthwise, wherein the indication barrel functions to indicate the set dose, and functions separately from the dose setting mechanism.

Abstract
The present disclosure concerns an indication mechanism for an automatic applicator, particularly for insulin or other liquid preparations, particularly for multiple injection administration of set doses of a medicine from an exchangeable container, for example for the self-application of insulin by diabetes patients. An indication mechanism for an automatic applicator, having an assembly of at least two barrels movably coupled to each other has an indication barrel mounted on the driving barrel contains only marking on its external surface and is co-axially connected to the pull-push control nut.
