Pap system

Abstract

A PAP system adapted for treatment of respiratory disease or sleep disordered breathing includes headgear adapted to engage a patient's head, a patient interface adapted to be secured to and sealed against a portion of a patient's face, in use, by the headgear, a flow generator adapted to be connected to the patient interface, and wherein the flow generator is adapted to be secured by a portion of the headgear to the patient's head, and an outlet tube to interconnect the flow generator and the patient interface. The patient interface includes a frame and a sealing arrangement supported by the frame. The sealing arrangement includes a seal portion, a body portion, and an inlet tube in communication with the outlet tube. The frame and the outlet tube are constructed of a relatively rigid material.

What is claimed is: 
     
         1 . A PAP system adapted for treatment of respiratory disease or sleep disordered breathing, comprising:
 headgear adapted to engage a patient's head;   a patient interface adapted to be secured to and sealed against a portion of a patient's face, in use, by the headgear;   a flow generator adapted to be connected to the patient interface, and wherein the flow generator is adapted to be secured by a portion of the headgear to the patient's head; and   an outlet tube to interconnect the flow generator and the patient interface;   wherein the patient interface includes a frame and a sealing arrangement supported by the frame, the sealing arrangement including a seal portion, a body portion, and an inlet tube in communication with the outlet tube,   wherein the frame and the outlet tube are constructed of a relatively rigid material.   
     
     
         2 . A PAP system according to  claim 1 , wherein the body portion and/or the inlet tube are constructed of a relatively rigid material. 
     
     
         3 . A PAP system according to  claim 1 , wherein the relatively rigid material is polycarbonate. 
     
     
         4 . A PAP system according to  claim 2 , wherein the frame, body portion, and inlet tube are integrally formed in one piece of the relatively rigid material. 
     
     
         5 . A PAP system according to  claim 1 , further comprising a flexible coupling between the outlet tube and the flow generator. 
     
     
         6 . A PAP system according to  claim 1 , further comprising a flexible coupling between the outlet tube and the inlet tube. 
     
     
         7 . A PAP system according to  claim 1 , wherein the seal portion includes a nasal seal. 
     
     
         8 . A PAP system according to  claim 1 , wherein the body portion includes a vent. 
     
     
         9 . A PAP system according to  claim 8 , wherein the vent is constructed of a relatively rigid material. 
     
     
         10 . A PAP system according to  claim 1 , wherein the frame includes a forehead support. 
     
     
         11 . A PAP system according to  claim 1 , wherein the headgear includes a cradle structured to engage the underside and/or sides of the flow generator. 
     
     
         12 . A mask arrangement, comprising:
 a patient interface adapted to be secured to and sealed against a portion of a patient's face in use; and   an outlet tube constructed of a relatively rigid material configured to receive a supply of pressurized gas from a flow generator in use,   the patient interface including a frame constructed of a relatively rigid material and a cushion supported by the frame, the frame including an inlet tube in fluid communication with the outlet tube.   
     
     
         13 . A mask arrangement according to  claim 12 , further comprising a flexible joint provided between the outlet tube and the inlet tube. 
     
     
         14 . A mask arrangement according to  claim 13 , wherein the flexible joint includes a concertina connection or corrugated joint. 
     
     
         15 . A mask arrangement according to  claim 12 , further comprising an inflexible coupling provided between the outlet tube and the inlet tube. 
     
     
         16 . A mask arrangement according to  claim 12 , wherein the outlet tube and the inlet tube are rotatably coupled to one another. 
     
     
         17 . A mask arrangement according to  claim 12 , wherein the outlet tube and the inlet tube are slidably coupled to one another. 
     
     
         18 . A mask arrangement according to  claim 17 , wherein the slidable coupling is arranged to allow slidable adjustment of the combined length of the inlet tube and the outlet tube to adapt to different forehead heights. 
     
     
         19 . A mask arrangement according to  claim 12 , wherein the outlet tube and the inlet tube are coupled to one another by a ball joint. 
     
     
         20 . A mask arrangement according to  claim 12 , wherein the outlet tube and the inlet tube are coupled to one another by a connector portion including headgear strap connectors.
