Abstract: Foldable device for isolating a patient, comprising a chamber (2) having a wall (21) that defines, in an unfolded position, a region (3) for receiving and isolating a patient, a base (1) on which the patient is placed in the unfolded position, and a support structure (4) for holding the wall (21) of the chamber (2), wherein the base (1) comprises contiguous modules in a longitudinal direction which allow the base (1) to be folded between contiguous modules.
