Abstract
Abstract A casualty transport system which provides substantially complete splinting, thermal protection and buoyancy for a patient transported by land, sea or air. The system is particularly suited for ship-to-shore, ship-to-ship or ship-to-helicopter transfers and for mountain rescue. The patient is placed in a glass reinforced plastic body shell having a removable lid which covers all but the head. The body shell is provided with a foam plastic lining premoulded to a 75 percentile man and close splinting, if required, can be achieved by a cast-in-place technique. Lifting handles and lugs and towing eyes are provided on the exterior of the body shell to facilitate lifting and handling.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A casualty transport system comprising: (a) a substantially rigid elongated concave body shell member dimensioned to receive a patient in a prone position through an open side thereof; (b) a substantially rigid self-supporting prefabricated lid member detachably securable over said open side of said body shell to thereby cover said patient from feet to neck; and (c) a lining of resilient polyurethane foam preformed to the shape of a 75 percentile man, for both resiliently supporting said patient in said body shell and conferring buoyancy and thermal protection to the transport system.
Claim 2
Dependent Claim
92 words
A casualty transport system comprising: (a) a substantially rigid elongated concave body shell member dimensioned to receive a patient in a prone position through an open side thereof; (b) a substantially rigid self-supporting prefabricated lid member detachably securable over said open side of said body shell to thereby cover said patient from feet to neck; and (c) a lining of resilient polyurethane foam preformed to the shape of a 75 percentile man, for both resiliently supporting said patient in said body shell and conferring buoyancy and thermal protection to the transport system.
Claim 3
Dependent Claim
21 words
A casualty transport system as claimed in claim 1, including lifting handles secured to an outer surface of said body shell.
Claim 4
Dependent Claim
26 words
A casualty transport system as claimed in claim 1, including lifting eyes on an outer surface of said body shell to facilitate suspension of said system.
Claim 5
Dependent Claim
28 words
A casualty transport system as claimed in claim 1, including towing eyes at each end of said shell to facilitate towing of said system in an aqueous medium.
Claim 6
Dependent Claim

A casualty transport system as claimed in claim 1, including skid members on said body shell to facilitate sliding movement of said system.
Claim 8
Dependent Claim
28 words
A casualty transport system as claimed in claim 1 including ballast means in said shell member whereby said system floats in an aqueous medium with a head-up attitude.
Claim 9
Dependent Claim
19 words
A casualty transport system as claimed in claim 1, wherein said lid member includes a foam lining secured thereto.
