Title
(EN) SUBSTANCE AND METHOD FOR PREVENTING THE TRANSMISSION OF VIRUSES IN THE RESPIRATORY SYSTEM
(FR) SUBSTANCE ET MÉTHODE POUR EMPÊCHER LA TRANSMISSION DE VIRUS DANS LE SYSTÈME RESPIRATOIRE
Abstract
(EN) The invention relates to a system for generating air adapted to prevent the infection of airborne viruses in an indoor environment. The system comprises an aerosol generator, at least one air aerosol concentration meter and at least one control unit. The supply means provide a certain flow rate of sodium bicarbonate (NaHCO3) saline solution to the aerosol generator. The aerosol generator generates a drop aerosol of a saline solution which is conveyed into the indoor environment and can be breathed by individuals. The aerosol concentration meter provides the control unit with a measurement of the concentration of aerosol drops in the air in the indoor environment. The control unit controls the aerosol generation means so that they supply the appropriate amount of aerosol in the indoor environment to obtain a predetermined sodium bicarbonate (NaHCO3) concentration. The invention also relates to a method for preventing the transmission of the infection.
(FR) L'invention concerne un système de génération d'air conçu pour empêcher l'infection par des virus présents dans l'air dans un environnement intérieur. Le système comprend un générateur d'aérosol, au moins un compteur de concentration d'aérosol d'air et au moins une unité de contrôle. Les moyens d'alimentation fournissent un certain débit de solution saline de bicarbonate de sodium (NaHCO3) au générateur d'aérosol. Le générateur d'aérosol génère un aérosol de gouttes d'une solution saline qui est transporté dans l'environnement intérieur et peut être respiré par des individus. Le compteur de concentration d'aérosol fournit à l'unité de contrôle une mesure de la concentration de gouttes d'aérosol dans l'air dans l'environnement intérieur. L'unité de contrôle contrôle les moyens de génération d'aérosol de telle sorte qu'ils fournissent la quantité appropriée d'aérosol dans l'environnement intérieur pour obtenir une concentration prédéterminée de bicarbonate de sodium (NaHCO3). L'invention concerne également une méthode de prévention de la transmission de l'infection.
