ABSTRACT:
A blank from which a plaster splint or cast is formed on an injured member consists of a strip, or stack of strips, of fabric impregnated with dry powdered plaster of paris enclosed between two sheets of non-water-absorptive material. The sheets are joined at their side edges to retain the fabric strip between them. The sheet which will be at the outward side of the completed splint or cast is perforated to enable water to be applied through it to wet the plaster powder.
The other sheet, which will be at the inward side of the completed splint or cast adjacent to the member on which the splint or cast is applied, has discrete cushion elements spaced apart over it. These cushion elements provide padding between the splint or cast and the member and also permit air circulation in the interface between the splint or cast and the member. A heat barrier is provided between the plaster and the member on which the splint or cast is formed for shielding the member from the heat that is generated by the setting and hardening of the plaster.
In use the plaster in the blank is wetted to become paste. The blank is then laid on the member that is to have the splint or cast applied to it and is shaped to conform to the member while the plaster is still soft. The plaster sets and hardens with the splint or cast in place on the member.
