Abstract

Abstract A transit isolator which comprises: (i) a first frame including (a) a pair of spaced generally parallel horizontal members, from which is slidably suspended an isolator in the form of a flexible film envelope having a plurality of sleeves in the sides thereof, (b) a basal structure, preferably comprising a stretcher, adapted to support said horizontal members, and (c) an end frame defining a closable port through which a patient may be conveyed into and out of the flexible film envelope; and (ii) a second frame comprising an end section adapted to slide along the horizontal members of said first frame and to which is attached that end of said flexible film envelope remote from the closable port, whereby movement of said end section along the horizontal members of the first frame causes the flexible film envelope to become compressed in the manner of a concertina in the direction towards said closable port.
