ABSTRACT:
A nose protection shield designed to be custom fitted to the exterior shape of a nose which is constructed of a hydrophilic thermoplastic having a thickness of between one-half millimeter to one millimeter. The nose protection shield is constructed by making a cast of the person's nose by applying a first hardenable material onto the nose, causing this first hardenable material to harden, removing the cast after such is hardened, filling of the cavity of the cast with a second hardenable material, permitting the second hardenable material to harden to form a model, removing the model from the cast, placing a thin, flexible plastic sheet on the model, drawing a vacuum in proximity of the model which causes the sheet to be drawn tightly against the model, apply heat for a short period of time to the sheet to a sufficient level to cause the at-rest shape of the sheet to be deformed and assume the new configuration of the model, and then removing of the sheet from the model.
