Abstract
Abstract This invention is an inflatable, anti-contamination enclosure for use in connection with emergency vehicles for transporting contaminated casualties from an accident site to medical facilities. The enclosure may be rolled up and stored in a convenient place when not in use. When needed, the enclosure can be rolled out on the floor of the emergency vehicle. As the enclosure is inflated, adhesive strips on the outside of the enclosure are exposed to secure the same against the top and side of the emergency vehicle. All openings into the enclosure are provided with flaps having a fabric loop and hook material for securing the same.

Claim 1
Independent Claim
147 words
An apparatus for transporting contaminated persons comprising: (a) a self-propelled vehicle having an enclosed vehicle compartment for transporting persons; (b) enclosure means formed with a liquid impervious sheet material disposed within said vehicle compartment and having a generally retangular configuration including one sealed end and one open end through which said enclosure means may be entered; (c) said enclosure means further including an inflatable support structure for supporting said liquid impervious sheet material including a series of parallel, inflatable tubes and a maniford feed interconnecting said parallel tubes; and (d) closure means comprising door members extending from sides of said rectangular configuration adjacent said open end formed with a liquid impervious sheet material for sealing said open end of said enclosure means when said enclosure is in an inflated condition, so that upon inflation an enclosure, hermetically sealed at ambient pressures, is formed within said vehicle compartment.
