FIELD: chemistry.
SUBSTANCE: group of inventions relates to medicine, namely to disinfecting systems for medical devices. For this purpose hydrogen peroxide solution is used for disinfection of contact lenses. To increase effective time of activity of hydrogen peroxide solution to 6 hours and its residual concentration lower than 100 ppm catalyst is used. Components for disinfection of contact lenses are placed into device, which includes a) container for water solution of hydrogen peroxide, containing effective quantity of vinylpyrrolidone copolymers and b) container, which contains disk, representing substrate with catalytic covering, with disk having to be completely submerged into hydrogen peroxide solution. Catalyst application provides increased concentration of oxygen peroxide by at least 80%.
EFFECT: group of inventions make it possible to use one-stage system for cleaning and disinfection of contact lenses, which is convenient for user.
