FIELD: medicine.
SUBSTANCE: invention relates to drug-dosing device. Device includes at least one metal component, which has at least one non-metal surface, which is in contact with drug when device is stored or applied, with said non-metal surface having surface of contact with underlying metal component, containing metal-fluoride and/or metalcarbide compounds, and content of oxygen in contact surface, measured by method of X-ray photoelectronic spectroscopy, constitutes less than approximately 15 at.%.
EFFECT: prevention of destruction and/or corrosion of internal surface of drug-dosing device.
