Claims1
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;
