  • Patent number: 10765830
    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 connected to a mask that covers at least the nostrils of a patient. The valve structure includes a housing with an inlet pressure port connected to the air flow generator, and an ambient pressure port. Within the housing is an expiratory membrane, an expiratory valve seat, an inspiratory membrane, an inlet pressure valve seat, an inspiratory valve seat, and an inspiratory membrane segmentation structure configured to segment the movement of the inspiratory membrane into at least a first portion and a second portion. An expiratory valve in fluid connection with the inlet pressure port is formed by the expiratory membrane and the expiratory valve seat. An inlet pressure valve is formed by the inlet pressure valve seat and the first portion of the inspiratory membrane.

  • Publication number: 20200206449
    Abstract: A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect each other 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 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.

  • Patent number: 10556081
    Abstract: A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect each other and create a braid, and a longitudinal axis that runs along the lumen, wherein the filaments intersect the longitudinal axis at a braid angle. The braid angle can be varied by compressing or 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.

  • Publication number: 20180064899
    Abstract: A nasal pillow system for treating sleep apnea is disclosed that may include a nasal pillow. The pillow has a cavity wall that defines a cavity, and two nasal interface structures connected to and extending away from the cavity wall. The nasal interface structures are in fluid communication with cavity. Each nasal interface structure includes a conical nasal interface, a cylindrical trunk structure connected to conical nasal interface and an annular relief pocket connected to the cylindrical truck structure and the cavity wall. The connection between the annular relief pocket and the cavity wall defines substantially a plane, and a first portion of the annular relief pocket extends away from the plane and a second portion extends towards the plane.

  • Publication number: 20180049638
    Abstract: Apparatus, systems, and methods are provided for treating obstructive sleep apnea. A unitary valve assembly removably located inside the exterior profile of a nasal pillow mask uses positive airway pressure from a low-flow hose to automatically create an on-demand therapeutic air splint in the pharynx. During inspiration the mask's valving system allows room air to be inspired. During exhalation another valve governs therapeutic backpressure equal to the prescribed pressure setting of the CPAP blower machine. The mask may be worn when the CPAP blower machine is off, and systems are provided for turning the CPAP blower machine on only when needed.
