Abstract

The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. A bleed port for release of exhaled air is defined through a conical vent projecting normally to the path of the incoming air flow, and continues through a nipple extending to the exterior of the air conduit. In one embodiment, a pair of nasal inserts are integral with a nasal cannula body, with bleed ports axially aligned with each insert. In another embodiment, each insert is independently connected to a separate, thin-walled, flexible supply line.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A respiratory interface for the treatment of breathing problems configured to be in flow communication with at least one of a user's nostrils, the respiratory interface comprising:
 at least one hollow body;   at least one inhale aperture;   at least one exhale aperture; and   at least one valve;   wherein the at least one valve is not parallel to the at least one inhale aperture during inhalation during use.   
     
     
         2 . The respiratory interface of  claim 1 , wherein the at least one valve repositions in response to inhalation. 
     
     
         3 . The respiratory interface of  claim 1 , wherein the at least one valve repositions in response to exhalation. 
     
     
         4 . The respiratory interface of  claim 1 , wherein the at least one valve is adapted to be in at least a partially closed position during exhalation. 
     
     
         5 . The respiratory interface of  claim 1 , wherein the at least one valve is adapted to be in at least a partially open position during inhalation. 
     
     
         6 . The respiratory interface of  claim 1 , wherein the at least one valve is configured to impede flow in an exhalation direction more than in an inhalation direction. 
     
     
         7 . The respiratory interface of  claim 1 , wherein the at least one valve is movable from a closed position during inhalation. 
     
     
         8 . The respiratory interface of  claim 1 , wherein the at least one valve is adapted to be operatively associated with at least one stop. 
     
     
         9 . The respiratory interface of  claim 1 , wherein the respiratory interface is adapted to contact a user's nose. 
     
     
         10 . The respiratory interface of  claim 1 , wherein the respiratory interface is adapted to contact at least one of a user's nostrils. 
     
     
         11 . The respiratory interface of  claim 1 , wherein the respiratory interface is adapted to traverse at least a portion of the bottom of a user's nose. 
     
     
         12 . A respiratory interface for the treatment of breathing problems configured to be in flow communication with at least one of a user's nostrils, the respiratory interface comprising:
 at least one hollow body;   at least one inhale aperture;   at least one exhale aperture; and   at least one valve;   wherein the at least exhale aperture is not parallel to the at least one inhale aperture during inhalation during use.   
     
     
         13 . The respiratory interface of  claim 12 , wherein the at least one valve repositions in response to inhalation. 
     
     
         14 . The respiratory interface of  claim 12 , wherein the at least one valve repositions in response to exhalation. 
     
     
         15 . The respiratory interface of  claim 12 , wherein the at least one valve is configured to impede flow in an exhalation direction more than in an inhalation direction. 
     
     
         16 . The respiratory interface of  claim 12 , wherein the at least one valve is movable from a closed position during inhalation. 
     
     
         17 . The respiratory interface of  claim 12 , wherein the respiratory interface is adapted to at least one of contact a user's nose and traverse at least a portion of the bottom of a user's nose. 
     
     
         18 . A respiratory interface for the treatment of breathing problems configured to be in flow communication with at least one of a user's nostrils, the respiratory interface comprising:
 at least one hollow body;   at least one inhale aperture;   at least one exhale aperture; and   at least one valve having a proximal surface and a distal surface;   wherein inhaled gas contacts the said distal surface during inhalation and exhaled gas contacts the said proximal surface during exhalation during use.   
     
     
         19 . The respiratory interface of  claim 18 , wherein the at least one valve repositions in response to inhalation. 
     
     
         20 . The respiratory interface of  claim 18 , wherein the at least one valve repositions in response to exhalation.
