Problems solved by technology

Second, traditional masks have built-in intended leak for constant "CO2 out"
Third, these systems achieve the desired pressure by using high airflow rates to create backpressure at the mask end, where air leaks
Users don't like the side effects mentioned above, as well as having to wear an uncomfortable, claustrophobic mask, being tethered to a pressurized console, the noise of the console, traveling with bulky equipment, and loss of personal space in bed
Noise is even more problematic as it can cause discomfort to the patient's sleeping partner, further disrupting compliance

Abstract

A sleep mask valve structure for treating a patient suffering from obstructive sleep apnea is provided. The valve structure includes a rigid valve housing comprising an inspiratory valve and an adjustable expiratory valve. The housing defines an outside mask side and an intra-mask side, and further defines an expiratory airflow conduit accommodating airflow from the intra- mask side to the outsidemask side and an inspiratory airflow conduit accommodating airflow from the outside mask side to the intra-mask side. The expiratory airflow conduit includes at least two changes of direction, with each direction change greater than or equal to 75 degrees and the inspiratory airflow conduit includes comprising at least one change of direction greater than or equal to 75 degrees. The two paths share at least one change of direction.
