Embodiment Construction

[0112] Figures 1 to 11 Shown is a mask assembly 10 including a flexible structure 20 according to an embodiment of the present invention. As shown, the mask assembly 10 includes a flexible structure 20, a frame 40, a forehead support 50 (with one or more forehead cushions 52), an elbow 60 (with swivels 62) (which are attached to the frame and adapted to connected to an air delivery tube that delivers breathable gas to the patient); and a headgear assembly (not shown) adapted to be detachably connected to the frame (e.g., via the headgear slit or clip 61) and the forehead support (e.g., via headgear clip or slot 51) to hold the mask assembly in place on the patient's head during use. In embodiments, the flexible structure 20 may be retrofitted or otherwise provided to an existing mask (eg, existing cushion clips may be used to attach the flexible structure to an existing mask frame). For example, the mask assembly 10 may have a structure similar to that of the Resmed ACTIVAL...

Abstract

Respiratory mask 10 includes a flexible structure 20 adapted to engage a patient's face. The flexible structure includes a chamber filled with at least a first gel. The flexible structure is adapted to provide a very comfortable fit for the wearer while providing a good seal and even distribution of forces. Mask properties, such as seals, can be measured using a testing machine with an indenter that allows measurement of applied force as a function of indentation. The flexible structure includes the lip / chin area, nose bridge area and cheek area which can be tested such as in terms of stiffness and / or viscoelastic behavior.

Description

[0001] Application for cross-reference [0002] This application is a continuation-in-part of application number PCT / AU2008 / 001711 filed 17 November 2008 and claims AU2008902720 filed 29 May 2008, AU2008903294 filed 27 June 2008 EP08160921.6 filed on 22 July 2008, AU2009900323 filed on 30 January 2009, and AU2009902153 filed on 14 May 2009, the entirety of each of the above applications The contents are hereby incorporated by reference. technical field [0003] The invention relates to a breathing mask for delivering air or breathable gas at positive pressure. In particular, the present invention relates to a respiratory mask having an improved comfort or range of fit compared to prior art masks, and methods and devices for measuring and evaluating the performance of such masks. 1. Background technology [0004] The use of nasal continuous positive airway pressure (nasal CPAP) to treat sleep-disordered breathing (SDB) was first proposed by Sullivan, eg, in US Patent No. 4,...
