ABSTRACT:
A mask to protect physicians, dentists and technicians from spatter from patients afflicted with various diseases (including A.I.D.S.) is assembled from two parts, which may be shipped and stored flat, may be sterilized, and are so inexpensive in materials and cost of fabrication that they may be disposed of after use. In one form of the invention, a visor is formed of a flat piece of sheet rubber having two tails provided with interfitting snaps. The tails are brought around the back of the head and the proper snaps or other fasteners adjusted to accommodate the head size of the wearer. This operation causes the flat sheet to assume a curved visor shape fitting around the forehead. In another embodiment, a hole is punched in a curved sheet of elastic material of a size so that it may be drawn down over the head. In a further embodiment, a piece of stretchable rubber-like tubing has opposite ends attached to ends of the tails of the visor. The tubing is stretched around the back of the head, causing the visor to assume an upward convex shape and causing its inner edge to engage the forehead of the wearer. The shape of the sheet provides a bill similar to the preceding modification. Slits are formed near the outer edge of the visor. A transparent shield has dovetail projections on its upper edge which snap through the slits. Other cooperating fastening means may be used to assemble the visor and shield. The shield is supported by the visor and hangs down to about the chin, protecting the eyes, nose and mouth.
