Abstract

A unitary cast or splint forming device which has a layer of cast forming material contained within a water retaining pouch so that water added to the pouch does not wet the exterior. Padded and patient contact layers may be applied to the outside of the pouch.

Claims

1. A unitary splint forming device for a patient, comprising:

a patient contact layer formed of polyurethane film, with a first side and a second side;

a padded layer formed of polyurethane foam, with a first side and a second side, wherein said second side of said patient contact layer and said first side of said padded layer are in essentially laminar parallel contact;

an inner water containment layer formed of spun bonded polypropylene non-woven hydrophobic fabric, having a first side and a second side, with said first side thereof being in substantially laminar parallel contact with said second side of said padded layer;

an outer water containment layer formed of spun bonded polypropylene non-woven hydrophobic fabric, having a first side and a second side, with said first side thereof being substantially parallel to and spaced from said second side of said inner water containment layer, forming a space therebetween, and wherein there are perforations in said outer water containment layer whereby liquid water applied to the second side thereof may pass through said layer into said space;

means for fastening said patient layer, padded layer, inner water containment layer and outer water containment layer together; and

a casting member formed fiberglass mesh with casting resin impregnated therein positioned in said space between said inner and outer water containment layers.
