An automatic applicator for liquid pharmaceutical preparations, the applicator comprising:
- an applicator housing;
- and
- an indication barrel;
- wherein the indication barrel contains a dose scale on an external surface to indicate the set dose at an inspection window fixed in the applicator housing;
- wherein the indication barrel is mounted slidingly, co-axially and lengthwise directly on an external surface of the driving barrel in the applicator housing, by a splined coupling comprising a plurality of keys located on the internal surface of the indication barrel and extending more than half of the length of the indication barrel, the longitudinal axis of the keys being arranged parallel to a longitudinal axis of the driving barrel;
- wherein the working range of the indication barrel is within the applicator housing;
- wherein the driving barrel is mounted rotateably within the applicator housing and wherein when a dose is to be set, the driving barrel is turned clockwise, looking in the direction of a needle, or anti-clockwise to correct the dose;
- wherein the driving barrel is connected to a driving element in the form of a helical spring and to a mechanism for medicine dose setting that comprises a trigger used in conjunction with the helical spring;
