On connaît déjà plusieurs dispositifs de traitement de l'air par flux laminaire ou flux turbulent. Les appareils à flux laminaires sont en installations fixes et très coûteuses. Les appareils à flux turbulent mis sur le marché actuellement manqueraient d'après les utilisateurs, de performances particulièrement en milieu Several air treatment devices are already known by laminar flow or turbulent flow. Laminar flow devices are in fixed installations and very expensive. According to users, the turbulent flow devices currently on the market are lacking in performance, particularly in
hospitalier.hospital.
Les appareils de traitement de l'air par flux laminaire représentent le système le plus performant pour la protection contre l'aérobiocontamination, mais leur nombre est limité er tous les malades qui en auraient besoin n'en profitent pas, et sont alors placés en chambre ordinaire sans traitement de l'air. D'autre part il manque sur le marché des cellules d'isolement avec filtration haute efficacité protégeant des maladies contagieuses de malades devant être transportés en milieu hospitalier ou en Laminar air treatment devices represent the most efficient system for protection against aerobiocontamination, but their number is limited and all patients who need it do not benefit from it, and are therefore placed in room ordinary without air treatment. On the other hand, there is a lack on the market of isolation cells with high-efficiency filtration protecting contagious diseases from patients who have to be transported to hospitals or
ambulance ou dans toutes situations. ambulance or in any situation.
Avantageusement ce dispositif évite à un malade d'être contaminé et Advantageously, this device prevents a patient from being contaminated and

Avantageusement le dispositif filtre par aspiration les premieres The device according to the invention operates in such a way that the air is sucked into a primary filter, then maintained in turbulence in a specific zone provided with low-voltage tubes with ultraviolet radiation, then passing through blades d '' a motor, then compressed by compression into a high efficiency terminal filter. Advantageously, the device filters the first by suction
particules de taille supérieure, puis détruit par rayonnement ultra- larger particles and then destroyed by ultra-
violet les micro-organismes vivants maintenus en suspension à l'aide d'un second filtre le temps nécessaire de turbulence pour leurs destructions, puis refoule l'air par compression dans le filtre terminal haute efficacité, lui-méme comportant des étalements de degré de filtration pour retenir les allergènes de taille supérieure à 0,3p. Avantageusement le filtre primaire muni de joints étanches retient purple living microorganisms kept in suspension using a second filter the necessary turbulence time for their destruction, then pushes the air by compression into the high efficiency terminal filter, itself comprising degree spreads filtration to retain allergens larger than 0.3p. Advantageously, the primary filter fitted with tight seals retains
les particules de taille importante. large particles.
