摘要

"Improvements in and relating to a mechanism of dosage for an implementation mechanism of medicine".The present invention relates to a device for applying drug, such as an injector for self-administration of a medicament.There is a need to display the amount of dosage measure of the medicine in the knob in the figures are sufficiently large and clear to be readable by those users having a degree of vision.Impaired.It is described a mechanism indicator of dose for an application device product having a housing (4),The mechanism of the dose indicator comprising a dose indicator element (6) having a first thread (40) for coupling with the housing (4) and an element of the glove of the indicator (8) and a second fiLethe (48) for coupling with the housing (4) in which the element of the glove of the indicator (8) is coupled on the element indicator of dose (6).In order to enable axial movement on and prevent the movement of rotation on between them.And in which the step of the second thread (48) is different from the first thread step (40) so as to cause an axial displacement of the element of different sleeve during axial displacement of the indicator.The register of the dose.
