A patient enclosure for ventilator apparatus comprising a base member (10) and a liftable cover member (12) which in an operative position defines a patient receiving chamber having at least one aperture (13) in the cover member for accommodating a portion of a patients body, the or each such aperture in the cover member being open along an edge of the cover member which overlies the base member in the operative position and containing a seal member for forming a substantially air tight seal in use between the cover member and the patients body and the base member, wherein the seal member takes the form of a flexible curtain (14) having a free edge overlying the base member and means such as straps (19) for tensioning a portion of the curtain to cause the curtain to seal against the base member and the patients body. The enclosure is used in conjunction with a source of oscillating air pressure to form a ventilator.
