Self-contained, intermittent positive airway pressure systems and methods for treating sleep apnea, snoring, and other respiratory disorders
Systems and methods provide a self-contained, intermittent positive airway pressure system for treating sleep apnea, snoring, and other respiratory disorders. The systems and methods provide an air flow director that can be worn in or over the nose of the individual in communication with an upper airway. The systems and methods provide an airflow regulation assembly that can also be worn in its entirety by the individual in communication with the air flow director. The airflow regulation assembly includes a source of positive pressure. The airflow regulation assembly intermittently operates the source of positive pressure to increase positive air pressure in the air flow director sufficient to resist tissue collapse in the upper airway during only a portion of the respiratory cycle less than the entire respiratory cycle.
1. A system to aid respiration of an individual, comprising:
a mask comprising a first mask inlet valve and a mask outlet valve, wherein the first mask inlet valve is configured for one-way flow into the mask;
a self-contained airflow manifold comprising an air inlet valve and a positive pressure source configured to be worn by the individual and comprising a controller configured to intermittently operate the positive pressure source to increase positive air pressure in the mask to resist tissue collapse in the upper airway during only a portion of a respiratory cycle less than the entire respiratory cycle;
an air path connecting the airflow manifold to the mask;
wherein the positive pressure source is configured to supply positive air pressure from the air inlet valve to the first mask inlet valve.
2. The system of claim 1 wherein the mask outlet valve is configured for one-way flow out of the mask.
3. The system of claim 1 wherein the mask comprises a second mask inlet valve, wherein the second mask inlet valve is configured for one-way flow into the mask.
4. The system of claim 1 wherein the airflow manifold comprises an air outlet valve.
5. The system of claim 4 wherein the air outlet valve is configured for one-way flow out of the airflow manifold.
6. The system of claim 4 wherein the air path comprises a first airflow pathway connecting the first mask inlet valve and the air inlet valve, and comprises a second airflow pathway connecting the mask outlet valve and the air outlet valve.
7. The system of claim 1 wherein the positive pressure source comprises a turbine.
8. The system of claim 1 wherein the positive pressure source comprises a blower.
9. The system of claim 1 wherein the controller includes at least one sensor communicating with the system to sense at least one condition relating to the respiratory cycle.
10. The system of claim 1 wherein the controller includes at least one sensor communicating with the airflow manifold to sense at least one condition relating to the respiratory cycle, and wherein the controller includes a processing element including preprogrammed rules that predict, based upon at least one sensed condition, the likely onset of tissue collapse in the upper airway.
