The novel splint-cast, before use, is a longitudinally flexible strip consisting of fibreglass reinforcing mat overlying and sealed adjacent an insulating layer at least partially by a non-permeable wrap material. On the other side of the insulating layer is a liner material of preferably a wool/cotton composition. The splint-cast blank may be prepared for use by passing a curable hardening agent into a vacuumed envelope formed by the wrap and the insulating material or the wrap and a latex layer, the fibreglass reinforcing mat absorbing the hardening agent along the length of the splint-cast blank. Before the hardening agent sets, the splint-cast is applied to an injured limb as a bandage but with consecutive wrappings about the limb in spaced relationship to each other. The splint-cast is simple and convenient to both prepare for use and apply. The open wrapping nature of the splint-cast on an injured limb permits air circulation while also providing desired firm support.
A splint cast formed of a rigid, composite elongated strip having a first and second terminal portions, said first terminal portion being disposed in a substantially straight line and adapted to lie along a patient's limb, said strip having a portion intermediate said first and second terminal portions, said intermediate portion being formed as a spiral adapted to fit securely around a portion of a living being, said spiral having a plurality of turns enveloping said first terminal portion, said turns being spaced longitudinally in order to provide intermediate open spaces, said first terminal portion being tucked underneath a plurality of said turns of said intermediate portion, the composite strip comprising a rigid, water resistant layer attached to a water-resistant heat insulating layer which is on the inside of the spiral, the rigidity and configuration of the splint being such as to resist twist about the axis of the spiral, and being such as to resist compression along the axis of the spiral.
A method of providing a splint cast on a patient's limb, said splint cast comprising an elongate hardenable splint cast blank having first and second terminal portions and a portion intermediate said first and second terminal portions, said blank comprising a hardenable water resistant layer attached to a water resistant heat insulating layer, said method comprising:
