摘要
A device for preventing an individual from inhaling germs, foreign bodies, and the like. The device includes only a single sheet of a relatively light-weight plastic material which has an outer convex surface area and an opposed inner concave surface area defining for the sheet a hollow interior space adapted to receive the nose, mouth, and chin of an individual, with the sheet having connected thereto a structure for mounting the sheet on the head of the individual in such a way that while the nose, mouth, and chin of the individual are in the hollow interior of the sheet nevertheless the nose, mouth, and chin do not engage the inner surface area of the sheet. Preferably the sheet has a flat portion adapted to extend in front of the eyes and having a pair of regions to be situated respectively in front of the eyes, these regions being flat and clear and being capable of permitting light to pass through with substantially no light loss and without distortion of light rays so that the vision of the individual using the device will be substantially uneffected by the device.
