Flexible cpap mask

Abstract

A respiratory interface device includes a respiratory mask that interfaces with a face of a patient. The respiratory mask comprises a body portion that forms an enclosure around a nose of a patient and at least one set of headgear strap flanges. The body portion is substantially entirely manufactured from an elastomeric material. A bellows-like structure is integrally molded in the body portion to create a sealing interface between an inner bottom portion of the mask and the patient's nose.

What is claimed is: 
     
         1 . An interface device comprising:
 a respiratory mask comprising:
 a body adapted to form an enclosure around a nose of a patient, wherein the entire body is manufactured from an elastomeric material; and 
 a bellows-like structure integrally molded in a mustache region of the body. 
   
     
     
         2 . The interface device of  claim 1 , wherein the bellows-like structure is adapted to create a sealing interface between a bottom portion of the mask and a patient's nose. 
     
     
         3 . The interface device of  claim 1 , wherein the body is substantially triangular in shape so as to fit contours of a patient's face from above a nose to a mustache area, located between the nose and lips. 
     
     
         4 . The interface device of  claim 1 , further comprising two sets of headgear strap flanges. 
     
     
         5 . The interface device of  claim 4 , wherein the headgear strap flanges are materially integral with the body. 
     
     
         6 . The interface device of  claim 4 , wherein a first set of headgear strap flanges is located at a bottom portion of the body and a second set of headgear strap flanges is located at a top portion of the body. 
     
     
         7 . The interface device of  claim 6 , wherein the first set of headgear strap flanges is upwardly angled and the second set of headgear strap flanges is downwardly angled. 
     
     
         8 . The interface device of  claim 1 , further comprising one or more supply tubes coupled to the body portion. 
     
     
         9 . The interface device of  claim 8 , wherein the one or more supply tubes extend for a distance along a plane defined by a base of the mask and then bend downward. 
     
     
         10 . The interface device of  claim 8 , further comprising a swivel component coupled to the one or more supply tubes. 
     
     
         11 . The interface device of  claim 1 , further comprising one or more air inlets extending from the body. 
     
     
         12 . The interface device of  claim 11 , wherein two air inlets are materially integral with the body such that each air inlet extends from a respective side portion of the body. 
     
     
         13 . The interface device of  claim 12 , wherein the two air inlets extend in a substantially upward direction. 
     
     
         14 . A respiratory mask comprising:
 an elastomeric body;   a bellows-like structure integrally molded in a mustache region of the body; and   at least one headgear strap flange integrally molded with the body.   
     
     
         15 . The respiratory mask of  claim 14 , wherein the body is adapted to form an enclosure around a nose of a patient, and wherein the entire body is manufactured from an elastomeric material. 
     
     
         16 . The respiratory mask of  claim 14 , further comprising a first set of headgear strap flanges coupled to a bottom portion of the body. 
     
     
         17 . The respiratory mask of  claim 16 , further comprising a second set of headgear strap flanges coupled to a top portion of the body. 
     
     
         18 . The respiratory mask of  claim 17 , wherein the second set of headgear strap flanges are downwardly angled. 
     
     
         19 . The respiratory mask of  claim 16 , wherein the first set of headgear strap flanges are upwardly angled. 
     
     
         20 . A respiratory mask comprising:
 elastomeric mask means for forming an enclosure around a nose of a patient; and   bellows integrally molded in the mask means for creating a sealing interface between an inner bottom portion of the mask means and a bottom portion of a patient's nose.
