Abstract: A valve structure for treating a patient suffering from obstructive sleep apnea is provided. The valve structure is connected to an air flow generator and is connected to a mask that covers at least the nostrils of a patient. The valve structure includes an inlet pressure port attached to the air flow generator and an expiration valve that includes an expiratory membrane, a primary seat and a secondary seat. During inspiration, the expiratory membrane forms a seal with the primary seat, and during expiration, the expiratory membrane forms a seal with the secondary seat.

Abstract: The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected to the air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half, and the back pressure is varied such that during the start of the first half, the back pressure is between 0 and 50% of a peak back pressure, and increases to a peak back pressure in the second half.

Abstract: A nasal pillow system for treating sleep apnea is disclosed that may include a nasal pillow.

Abstract: A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect one another, creating a braid. A longitudinal axis that runs along the lumen, and the filaments intersect the longitudinal axis at a braid angle. The braid angle can be varied by compressing or by expanding the matrix along the direction of the longitudinal axis. A polymer coating is applied to the matrix such that the matrix is substantially impermeable to air. The hose has two states: (1) a relaxed state where the hose does not experience a force in the direction of the longitudinal axis; and (2) a stressed state where the hose experiences a force in the direction of the longitudinal axis. The braid angle is larger in the relaxed state as compared to the stressed state. A method of manufacture for the hose is also disclosed.

Abstract: A blower for the treatment of a patient's sleep apnea is disclosed. The blower includes a start/stop button, an air pump, and a processor connected to the start/stop button and air pump. A user may input a snooze period (Tsnooze), a ramp period, (Tramp1), and an ultimate therapeutic pressure (TP). The processor performs an snooze function that allows a user to stop the delivery of pressure from the blower for the snooze period, after which the processor ramps the pressure gradually over the ramp period until plateauing at the ultimate therapeutic pressure. The processor may limit the number of snooze triggers that a patient may use.
