SYSTEM FOR EXPOSURE TO ALLERGENS, COMPRISING CHAMBER FOR MIXING AIR AND ALLERGENS, WHICH IS SEPARATED FROM EXPOSURE ROOM, IN WHICH PATIENTS ARE PLACED

摘要

FIELD: medicine.;SUBSTANCE: group of inventions relates to medical equipment. System for exposure to allergens comprises an allergens introduction device (8), an inlet air channel (21) and exposure room (2), containing air containing allergenic particles obtained by mixing the flow of allergenic particles (18) from device (8) for introducing allergens and air stream (20), which does not contain allergenic particles, supplied through inlet air channel (21). Room is configured to accommodate patients inhaling air containing allergenic particles to cause allergenic provocation. System comprises mixing chamber (9) limited by walls (13), separately from inlet air channel (21) and from room (2) for action, in which said mixing takes place between flow of allergenic particles (18) and air flow (20), not containing allergenic particles. Mixing chamber (9) comprises an allergen inlet opening (14), which is connected to the allergens introduction device (8) outlet opening and through which allergenic particles (18) stream penetrates, inlet for air, which is connected to inlet air channel (21) and through which penetrates air flow (20), not containing allergenic particles, wherein at least one allergen inlet opening (14) and at least one mixing chamber air inlet are located near each other and perpendicular to each other. Dispersing outlet is communicated with room (2) for action and through which airflow containing allergenic particles (26) obtained by mixing in mixing chamber (9) air flow (20), which does not contain allergenic particles, and flow of allergenic particles (18), enters exposure room (2). Near the air inlet for the air, mixing chamber (9) forms expansion (31) relative to the inlet air channel (21), which ensures expansion of air flow (20), which does not contain allergenic particles, when it enters chamber (9).;EFFECT: technical result consists in uniform distribution of allergenic particles in air.;14 cl, 7 dwg
