DOSE INDICATOR FOR DRUG ADMINISTRATION DEVICE Russian patent published in 2010 - IPC A61M5/315 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a dose indicator for a drug administration device which allows the user to specify multiple doses of an injected drug, and for introduction of the preset dose of a drug and application of said drug for the patient, preferentially by injection. The dose indicator for the drug administration device comprises a dose setup limb and a counting ring. The dose setup limb comprises an external thread and external grooves extending from proximal to distal ends. The counting ring is mutually coupled with the external grooves of the dose setup limb, so the counting ring can freely move axially along the external grooves relative to the dose setup limb, herewith being blocked by rotation relative to the dose setup limb.

EFFECT: invention makes it possible to maximise the indication indices and thereby makes them appropriate to be applied by the visually impaired users.
