ABSTRACT:
Mobile aeraulic isolation device (1a) 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 (1a) 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 device1a) 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). Device1a) forms a mobile protective isolation device for immunosuppressed persons.
