Abstract

The device has a casing (1) with an exhalation orifice comprising an exhalation valve (4), where the orifice is placed at proximity of a lower end of the casing. A deflector (5) has a tubular shape and an end (15) that is open and forms an exhaled gas outlet located concentrically around a part of a pipe (6). The pipe is connected to the casing at a level of an inlet orifice (21) via a connection part (7) which is made of a heat conductive material. The part (7) is placed inside a portion of the deflector. A gas outlet orifice (2) is located at proximity of an upper end of the casing.
