Abstract

L'invention concerne un dispositif de désinfection d'un volume contenant un fluide gazeux, comprenant un corps creux (2) comportant une surface interne réfléchissante (7), une ouverture d'entrée (3) et une ouverture de sortie (4), et une ou plusieurs sources (5) de rayonnement UV-C placées à l'intérieur du corps (2) ; le corps (2) délimitant une cavité optique générant un effet multiplicateur de l'intensité d'éclairage en raison de multiples réflexions à l'intérieur du corps (2). Le dispositif peut être utilisé dans des systèmes de respiration ou de ventilation assistés pour désinfecter l'air expiré par un patient.
