Abstract
Abstract A splint assembly for emergency treatment of patient fractures. The splint assembly includes two planar, rectangularly shaped members constructed of a suitable structurally rigid material. The planar members include respective arcuate through slots of identical dimensions. In operation, the members are placed in an overlapping position to receive a pair of carriage bolts passing through the arcuate slots. The members may be angularly oriented with respect to each other and locked in place by tightening the bolts. Recesses are also provided on opposing sides of the planar members to permit securement of straps or bandages. Additionally, the splint assembly may be provided to the user in a kit which includes a multiplicity of different sized planar members for use in a wide range of size configurations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
A splint assembly for emergency treatment of body fractures comprising: a. a pair of rigid, thin, generally rectangular planar members, each having a single arcuate slot, each slot being a segment of a circle of the same radius of curvature and each slot having substantially equal peripheral contour dimensions, and each slot having a substantially equal width dimension, said planar members positioned with respect to each other in at least partially contiguous and overlapping contact, said members being so mutually oriented that said slots in each said member may coincide; and, b. positioning and fastening means mounted to said planar members through said arcuate slots, for selectively and releasably locating and rigidizing said pair of planar members with respect to each other in accordance with a predetermined positional relationship between the said planar members, said positioning and fastening means comprising: 1. a pair of carriage bolts, each of said carriage bolts being partially threaded and having a square neck with side dimensions substantially equal to said arcuate slot widths to prevent said bolts from rotating with respect to the edges of said slots, each of said bolts being free to move along the length of said slots when in the non-tightened state; and, 2. tightening means engaged with said threaded portions for securing said carriage bolts to said planar members with clamping action.

Claim 3
Dependent Claim
19 words
tightening means engaged with said threaded portions for securing said carriage bolts to said planar members with clamping action.
Claim 4
Dependent Claim
19 words
tightening means engaged with said threaded portions for securing said carriage bolts to said planar members with clamping action.
Claim 5
Dependent Claim
76 words
The splint assembly as recited in claim 1 wherein said tightening means includes: a. a pair of square nuts threadedly engageable with said carriage bolts; and, b. a pair oF washers around on said threaded portion of said carriage bolts, said washers having a peripheral outer dimension substantially greater than said widths of said arcuate slots, each of said washers contacting one of said planar members and one of said square nuts on opposing sides thereof.
Claim 6
Dependent Claim
41 words
The splint assembly as recited in claim 1 wherein said tightening means includes a pair of ball nuts, said ball nuts being threadedly engageable with said carriage bolts, said ball nuts further having radius substantially larger than said arcuate slot widths.
Claim 7
Dependent Claim
20 words
The splint assembly as recited in claim 1 wherein said first and second planar members are constructed of plywood material.
Claim 8
Dependent Claim
19 words
The splint assembly as recited in claim 1 wherein said first and second planar members are constructed of aluminum.
Claim 9
Dependent Claim
58 words
The splint assembly as recited in claim 1 wherein said pair of planar members include a plurality of transversely opposed and longitudinally directed recesses, said recesses for providing insert guides wherein said planar members may be secured to said body through a plurality of strap members passing around said body and through said recesses within said planar members.
