ABSTRACT:
The disclosure relates to a pneumatic splint formed of three similarly shaped walls of flexible thermoplastic material. The inner and outer walls are of identical shape and are peripherally bonded to each other. The intermediate wall is of lesser peripheral dimension and has three of its edges bonded to corresponding edges of the inner and outer walls and the fourth edge bonded to an intermediate portion of the outer wall. The intermediate wall is provided with a plurality of spaced apertures and a plurality of equally spaced welded bonds to the outer wall. The application of fluid pressure to the interior of the splint when rolled into an annular configuration to loosely surround a human limb will expand the inner wall into intermittent engagement with the limb and the outer wall into a uniform, quilted cushion configuration.
