ABSTRACT:
An inflatable, cone-shaped mask is attached to one end of a hollow housing and a mouthpiece is attached to the other. A valve in the housing is switchable between two positions. In one position it directs breath from an active breather blowing in the mouthpiece into the mask to inflate it. In the second position it directs the breath through the mask, which may be sealably engaged about the nose and mouth of a passive breather to be resuscitated. A second valve in the housing prevents fluid from passing from the mask to the mouthpiece. A spin separator trap separates moisture from the breath of the active breather as it passes through the housing. A second spin separator trap prevents moisture that may leak from the first trap from falling into the breathing organs of the passive breather. A screen in the housing prevents regurgitation from the passive breather from entering the second valve chamber. When not inflated, the mask is foldable back over the housing. The entire device is sufficiently compact to fit in an ordinary-sized clothes pocket.
