<p>An enclosure (10) for isolating a patient comprises an external frame (12) and a flexible envelope (14) suspended from and hanging within the frame. The envelope has a bottom (16), top (18), two sides (20, 22), front (24) and a rear (26) wall portions, one of the side or front wall portions being fitted with a closable entry means (32) allowing entry of the patient. There is an opening (46) in one of the wall portions fitted with an integral filter means (48) adapted to filter out infectious particles from the air and to cooperate with a pump means (50), and a valve means (36) allowing uni-directional air passage from the outside to the inside of the enclosure. The pump means draws air through said filter means which creates a negative pressure inside the enclosure, whereby air flows in the direction valve-enclosure-filter means ensuring that no contaminating agents will escape from within the enclosure to the outside. <IMAGE></p> |
