Abstract
Abstract A device for providing assistance to persons with emphysema and problems relating to breathing. Essentially the invention provides means for applying pressure to the abdominal and lower rib region which assists in forcing air from a person''s lung. The pressure is applied during the exhalation phase of the breathing cycle and the pressure applying means is activated by the person''s efforts to exhale. The pressure is released upon completion of the exhalation phase avoiding interference with the inhalation phase.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
74 words
Apparatus for assistance in breathing which comprises a selfcontained fluid and actuating means for applying pressure to the abdomen and lower ribs over a time period equivalent to the exhalation phase in breathing, said means assisting in forcing air from a person''s lungs and releasable at the end of the exhalation cycle, and sensing means minimizing impediments to breathing and operable upon detection of breath upon exhalation for actUating said means for applying pressure.
Claim 2
Dependent Claim
74 words
Apparatus for assistance in breathing which comprises a selfcontained fluid and actuating means for applying pressure to the abdomen and lower ribs over a time period equivalent to the exhalation phase in breathing, said means assisting in forcing air from a person''s lungs and releasable at the end of the exhalation cycle, and sensing means minimizing impediments to breathing and operable upon detection of breath upon exhalation for actUating said means for applying pressure.
Claim 3
Dependent Claim
92 words
Apparatus for assistance in breathing which comprises a belt for attachment around the abdominal and lower rib region, said belt including expandable means, a reservoir connected to said expandable means and providing a self contained fluid supply, actuating means, and sensing means detecting the impingement of breath, said sensing means providing an output upon the beginning of exhalation to said actuation means whereby said actuating means is activated and causes fluid to flow from said reservoir to said expandable means during exhalation and to return to said reservoir at the end thereof.
Claim 4
Dependent Claim
92 words
Apparatus for assistance in breathing which comprises a belt for attachment around the abdominal and lower rib region, said belt including expandable means, a reservoir connected to said expandable means and providing a self contained fluid supply, actuating means, and sensing means detecting the impingement of breath, said sensing means providing an output upon the beginning of exhalation to said actuation means whereby said actuating means is activated and causes fluid to flow from said reservoir to said expandable means during exhalation and to return to said reservoir at the end thereof.
Claim 5
Dependent Claim
25 words
The apparatus as defined in claim 2 which said sensing means comprises a microphone supported in non-breathing impediment manner adjacent a person''s nose and mouth.
Claim 6
Dependent Claim
25 words
The apparatus as defined in claim 2 in which said expandable means comprises an elongated sack and said reservoir is compressible by said actuation means.
Claim 7
Dependent Claim
60 words
In a breathing assist apparatus, a pressure applying means for positioning around the abdomen and lower ribs, a reservoir of air connected to said pressure applying means in a self contained system, actuation means for alternately transferring air in said system to and from said reservoir and said pressure applying means, and breath signal detection means controlling said actuation means.
Claim 8
Dependent Claim
60 words
In a breathing assist apparatus, a pressure applying means for positioning around the abdomen and lower ribs, a reservoir of air connected to said pressure applying means in a self contained system, actuation means for alternately transferring air in said system to and from said reservoir and said pressure applying means, and breath signal detection means controlling said actuation means.
Claim 9
Dependent Claim
27 words
In a breathing assist apparatus as defined in claim 5, hand operated pump means for adjusting the pressure in said pressure applying means and in said reservoir.
Claim 10
Dependent Claim
69 words
Apparatus for assisting in breathing which comprises a self-contained fluid and actuating means for applying pressure to the abdomen and lower ribs over a time period equivalent to the exhalation phase in breathing, said means assisting in forcing air from a person''s lungs and releasable at the end of the exhalation cycle, said means for applying pressure being actuated periodically corresponding to the breathing cycle of inhalation and exhalation.
Claim 11
Dependent Claim
69 words
Apparatus for assisting in breathing which comprises a self-contained fluid and actuating means for applying pressure to the abdomen and lower ribs over a time period equivalent to the exhalation phase in breathing, said means assisting in forcing air from a person''s lungs and releasable at the end of the exhalation cycle, said means for applying pressure being actuated periodically corresponding to the breathing cycle of inhalation and exhalation.
