Abstract: A shielding device movable between a folded configuration, in which the shielding device is stored, and an expanded configuration, in which the shielding device is configured to be positioned over a patient to prevent a spread of aerosolized particles. The shielding device includes a flexible material configured to be movable between the folded configuration and the expanded configuration to form a tent portion, a wall of the tent portion defining an interior space within which the patient is received in an operative configuration and a tensile frame including a plurality of struts, each connected to a portion of the flexible material and biased toward the expanded configuration, in which each of the struts provide a tension across the portion of the flexible material to which it is connected, the struts being deformable toward the folded configuration so that portions of the flexible material may be folded against itself.
