ABSTRACT:
A disposable hood of unitary one-piece construction for maintaining a desired gas atmosphere about the head of a patient incorporates a novel attachment means for connecting a flexible conduit or hose to the hood. The hood itself is a generally bubble-shaped chamber molded of a transparent material with the top and sidewalls being joined in arcuate contours so that there are no sharp corners. Flat extension means extend from the bottom of the hood so as to lie flatwise on the bed, and an arcuate ballast member is adapted to fit closely around the hood and on the flat extension means to hold the hood in position on the bed.
