Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A person-to-person resuscitation device comprising: means for receiving breath from an active breather; means for applying breath to a passive breather; and valve means for permitting breath to pass from said means for receiving to said means for applying and for preventing fluid from passing from said means for applying to said means for receiving; said means for applying having an opening therein and including an inflatable bladder and a relatively rigid collar, said collar encircling said opening, supporting said bladder about said opening, and having one or more inflation ports in it; and said device further comprising a switchable means switchable from a first position to a second position for directing said breath through said one or more inflation ports to inflate said bladder when in said first position and for directing said breath to said passive breather through said opening in said second position.
Claim 2
Dependent Claim
146 words
A person-to-person resuscitation device comprising: means for receiving breath from an active breather; means for applying breath to a passive breather; and valve means for permitting breath to pass from said means for receiving to said means for applying and for preventing fluid from passing from said means for applying to said means for receiving; said means for applying having an opening therein and including an inflatable bladder and a relatively rigid collar, said collar encircling said opening, supporting said bladder about said opening, and having one or more inflation ports in it; and said device further comprising a switchable means switchable from a first position to a second position for directing said breath through said one or more inflation ports to inflate said bladder when in said first position and for directing said breath to said passive breather through said opening in said second position.
Claim 3
Dependent Claim
17 words
The resuscitation device of claim 1 wherein said switchable means is part of said means for applying.
Claim 4
Dependent Claim
29 words
The resuscitation device of claim 1, wherein said switchable means comprises means for closing said one or more inflation ports when said switchable means is in said second position.
Claim 5
Dependent Claim
41 words
The resuscitation device of claim 3 wherein said one or more ports comprises a circular hole in said collar and said means for closing comprises a rounded boss having a diameter equal to or greater than the diameter of said hole.
Claim 6
Dependent Claim
25 words
The resuscitation device of claim 3 wherein said means for closing includes means applying a bias force for closing said one or more inflation ports.
Claim 7
Dependent Claim
142 words
The resuscitation device of claim 5 wherein said collar comprises a resilient material and said means applying a bias force comprises a first hollow cylindrical member and a second hollow cylindrical member, said cylindrical members nested together so that the outer circumference of one cylindrical member abuts the inner circumference of the other cylindrical member, a contact member connected to said first cylindrical member, in contact with said collar, and engageable with said ports, said second cylindrical member attached to said collar and having a lip extending over the rim of said first cylindrical member opposite said collar, and the relative distances between said collar and said lip and said collar and said ring of said first cylindrical member being such that said lip presses against said rim and forces said contact member to compress said collar to provide said bias force.
Claim 8
Dependent Claim
19 words
The resuscitation device of claim 1 wherein said device is sufficiently compact to fit into an ordinary-sized clothes pocket.
