Mobile aeraulic isolation device ( 1 a) with variable geometry multi-block air diffusion chamber ( 4 ), comprising at least two mobile plenums ( 5,6 ) to protect a sensitive area such as a bed ( 2 ) against contaminating airborne aerosols. It comprises an air diffusion chamber ( 4 ) formed of at least two rigid plenums ( 5,6 ) mechanically connected together so as to be mobile relative to one another, and having a lower air diffusing surface ( 7,8 ) substantially planar and porous to air. Relative movement means ( 10 ) for mobile plenums ( 5,6 ) enable their positioning in relation to one another in at least two distinct relative positions. The device ( 1 a) comprises physical decontamination means ( 20,21,22,23 ) for moving air passing through it, air pressurising means ( 25 ), aeraulic connection ( 30 ) and air circulation means, and a mobile supporting chassis ( 12 ). The device 1 a) is characteristic in that it comprises complementary means for absolute movement ( 13 ) of the group of two rigid plenums ( 5,6 ) relative to chassis ( 12 ). So that its two plenums ( 5,6 ) are both mobile, both relative to one another and relative to chassis ( 12 ). Device 1 a) forms a mobile protective isolation device for immunosuppressed persons.
