Abstract
Device for extracting particles from exhaled breath, comprising a cooling system (16) for creating droplets by condensation of the water vapor contained in the exhaled breath; a droplet recovery unit (7) provided with a side wall (2) having a grid form and converging towards an outlet opening (9), allowing the droplets attracted towards said side wall (2) to flow along the latter towards the outlet opening (9); and a discharge electrode (1) mounted inside the droplet recovery unit (7), said side wall (2) of said droplet recovery unit (7) defining a counter electrode to said discharge electrode (1) in order to attract droplet-collecting particles carried by exhaled breath towards said side wall (2).
