Abstract

A device (1) for the disinfection of a volume containing a gaseous fluid, comprising a hollow body (2) having a reflective inner surface (7), an inlet opening (3) and an outlet opening (4), and one or more sources (5) of ultraviolet UV-C radiation placed inside the body (2); the body (2) defines an optical cavity generating a multiplicative effect of the illumination intensity due to multiple reflections inside the body (2). The device can be used in assisted breathing or ventilation systems for disinfecting the air exhaled by a patient when connected to an interface device (14) such as a mask.
