DEVICE FOR ISOLATING CONTAMINATED AIR IN STATIC INHALATION CHAMBER FOR SAMPLING Russian patent published in 2021 - IPC G01N1/22 

FIELD: medicine; biology.

SUBSTANCE: invention relates to the field of obtaining samples for examination in the gaseous state of vessels specially designed for medical purposes, with a device for holding samples of the contents. It can be used in the field of biomedical research, namely, in inhalation toxicology, to assess the concentration of substances in a static inhalation chamber. The device for isolating contaminated air in a static inhalation chamber for sampling is a tank with a side surface formed from a flat sheet by wrapping rotating bases. The device allows one to exclude the suction of external air into the inhalation system during sampling and to level the selective capture of aerosol particles of lower dispersion.

EFFECT: increased reliability of the results of the study, in general, when sampling only an isolated part of the contaminated air, while maintaining complete rest in the rest of the air environment of the inhalation chamber, as a result of which the specific amount of substance and aerosol particles in the aspirated air is completely identical to the air environment of the inhalation chamber at the time of air isolation.
