Abstract
Abstract An assembly for immobilizing the head of a trauma victim intended to be positioned on a stretcher board. The device includes a first sheet of flexible material which is to be mounted so that, when it is affixed to the board, a pair of normally-flaccid, open-sided loops are defined therein. The loops are intended to be at locations which straddle an intended location of the trauma victim's head. A pair of compressible blocks are also included. Each block is intended to be received within one of the normally-flaccid, open-sided loops. A block can be easily inserted into, and removed from, its corresponding loop because the loops are open-sided in nature. When the compressible blocks are received within the loops and constrained thereby, the blocks, together, define a seat in which the head of the trauma victim can be positioned.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
202 words
Apparatus for immobilizing the head of a trauma victim positioned on a stretcher board, comprising: (a) a first sheet of flexible material; (b) a second sheet of flexible material having a first face for engaging the stretcher board and a second, opposite face for mounting said first sheet of flexible material when said second sheet of flexible materials is stretched into a planar configuration; (c) means for mounting said first sheet of flexible material to the second sheet of flexible material such that a pair of normally flaccid, open-sided loops with open sides are defined in said first sheet of flexible material, wherein said pair of open-sided loops straddle an intended location of the trauma victim's head; (d) a pair of compressible blocks, each receivable within one of said loops through one of said open sides thereof to be constrained by its respective loop in a manner wherein one of said blocks, in combination with the other of said blocks, defines a seat in which the head of the trauma victim can be received; and (f) means for attaching an assembly of said first sheet of flexible material, said second sheet of flexible material, and said compressible blocks to the stretcher board.

Claim 3
Dependent Claim
24 words
Apparatus in accordance with claim 1 wherein each compressible block is similarly sized and shaped, and wherein each compressible block is triangular in cross-section.
Claim 4
Dependent Claim
17 words
Apparatus in accordance with claim 2 wherein each compressible block is made from a high-density polyfoam material.
Claim 5
Dependent Claim
60 words
Apparatus in accordance with claim 1 wherein said first sheet of flexible material and said second sheet of flexible material are substantially rectangular in shape, said first and second sheets of flexible material having substantially the same width, but wherein said first sheet of flexible material has a length greater than a length of said second sheet of flexible material.
Claim 6
Dependent Claim
34 words
Apparatus in accordance with claim 4 wherein said first sheet of flexible material is stitched to said second sheet of flexible material along elongated sides thereof to define said pair of flaccid, open-sided loops.
Claim 7
Dependent Claim
51 words
Apparatus in accordance with claim 5 wherein said first sheet of flexible material is stitched to said second sheet of flexible material along axes generally transverse to longitudinal axes of said sheets of flexible material at bases of said loops in order to further define said pair of normally-flaccid, open-sided loops.
Claim 8
Dependent Claim
103 words
Apparatus in accordance with claim 1 wherein the stretcher board has provided thereon one or more pads made of one of hook and pile material, and wherein said first face of said second sheet of flexible material has, provided thereon, patches, each made of one of hook and pile material such that, when an assembly of said first and said second sheets of flexible material is positioned in an intended location on the stretcher board wherein said seat in which the head of the trauma victim can be received is appropriately positioned, said patches will overlie reciprocal material pads on the stretcher board.
