Abstract
Abstract A patient care system for monitoring respiratory distress problems and providing therapeutic treatment comprising, a sensor for generating patient derived respiratory activity signals, detecting an apnea episode from the signals, and providing in response to a detected apnea episode, stimulation of the patient by a momentary inflation of a pneumatic means adapted for placement under the patient to raise the patient and induce loss of equilibrium for startling the patient into a natural respiration pattern.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
A patient care system for monitoring and treating respiratory distress problems comprising: means for sensing and generating respiratory activity signals; means responsive to said respiratory activity signals, for detecting a respiratory distress problem; and stimulating means responsive to said detecting means including inflatable fluid means adapted for placement under a patient to cause a loss of patient equilibrium, by a startling momentary raising action of a non-oscillatory type.
Claim 2
Dependent Claim
68 words
A patient care system for monitoring and treating respiratory distress problems comprising: means for sensing and generating respiratory activity signals; means responsive to said respiratory activity signals, for detecting a respiratory distress problem; and stimulating means responsive to said detecting means including inflatable fluid means adapted for placement under a patient to cause a loss of patient equilibrium, by a startling momentary raising action of a non-oscillatory type.
Claim 3
Dependent Claim
31 words
A patient care system according to claim 1 wherein said stimulating means further includes fluid supply means electrically connected from said detecting meaNs and adapted for momentarily inflating said pneumatic means.
Claim 4
Dependent Claim
29 words
A patient care system according to claim 2 wherein said fluid supply means includes air reservoir means for maintaining a predetermined air pressure value for inflating the fluid means.
Claim 5
Dependent Claim
22 words
A patient care system according to claim 1 including means responsive to said detecting means for counting each respiratory distress problem detected.
Claim 6
Dependent Claim
107 words
A patient care system for monitoring and treating respiratory distress problems comprising: mesans for sensing and generating respiratory activity signals; monitoring means responsive to said respiratory activity signals for providing an output signal upon detection of a respiratory distress problem; inflatable pneumatic means including an air mattress adapted for placement under a patient; pneumatic supply means including air reservoir means for maintaining a predetermined air pressure valve, energizable to inflate said pneumatic means; and means of a non-oscillatory type, responsive to said monitoring means output signal, for momentarily energizing said pneumatic supply means to provide a startling raising action adapted to cause a loss of patient equilibrium.
Claim 7
Dependent Claim
107 words
A patient care system for monitoring and treating respiratory distress problems comprising: mesans for sensing and generating respiratory activity signals; monitoring means responsive to said respiratory activity signals for providing an output signal upon detection of a respiratory distress problem; inflatable pneumatic means including an air mattress adapted for placement under a patient; pneumatic supply means including air reservoir means for maintaining a predetermined air pressure valve, energizable to inflate said pneumatic means; and means of a non-oscillatory type, responsive to said monitoring means output signal, for momentarily energizing said pneumatic supply means to provide a startling raising action adapted to cause a loss of patient equilibrium.
Claim 8
Dependent Claim
54 words
A patient care system according to claim 5 wherein said pneumatic supply means further includes: valve means; an energizable pump connected to said air reservoir through said valve means; and, a pressure switch when activated responsive to less than a predetermined level of air pressure in said air reservoir means for energizing said pump.
Claim 9
Dependent Claim
32 words
A patient care system according to claim 6 including switch means connected from the monitoring means for activating said pressure switch in the absence of an output signal from said monitoring means.
