[0069] refer to figure 1 Preferably, the headgear assembly 20 is attached to the mask assembly 15 in such a manner that the position of the mask assembly 15 can be adjusted relative to the straps of the headgear assembly 20 . The mask assembly 15 includes a frame assembly 70 , a patient-interfacing or patient-contacting cushion 75 , and a cushion support 80 interposed between the frame assembly 70 and the cushion 75 . Cushion support 80 includes holes (not shown) through which pressurized air may be delivered to the pressurization chamber of mask assembly 70, the pressurized air being delivered to the patient's airway. Typically the elbow 85 is loosely connected to the bore of the cushion support 80 . The swivel elbow includes a quick release connection 86 that connects to an air delivery tube (not shown), which in turn connects to air delivery means such as an air supply (not shown).

[0083] Figures 5C-5H Still another embodiment of the present invention is shown in which the adjustment mechanism allows for coarse and fine adjustment of the tension of the headgear. Figure 5C The entire mask assembly is shown, comprising a mask frame 800 having an elbow 805 including an anti-asphyxia valve 810 . A quick release fastener 815 is configured so that the patient can easily remove the headgear as described in U.S. Patent Application No. 10 / 235,846, filed September 6, 2002, which is incorporated herein by reference in its entirety middle. Figure 5D shows the quick release mechanism in the partially open position, while Figure 5E The quick release mechanism is shown fully open.

[0084] Strap 820 includes a pair of strap ends 820A and 820B for retaining the mask assembly on the patient's head. One of the strap ends such as 820B can be connected to one end of the mask frame in a fixed position by, for example, slot 821, thereby avoiding changes in the length of...

Abstract

Providing a comfortable low leak mask assembly for a non-invasive positive pressure air supply device (NIPPV) can improve patient compliance and / or treatment efficacy. The mask system includes: a headgear with straps that are substantially non-stretchable and / or fine-tuned; and / or a mask and / or cushion that includes various components to allow Selected locations on the patient's face improve / customize tightness and / or fit.

Description

technical field [0001] The present invention generally relates to whole face masks for use in non-invasive positive air pressure devices (NIPPA), continuous positive airway pressure devices (CPAP) and air delivery devices. Background technique [0002] Delivery of positive pressure breathable gas from a gas supply to a patient requires some kind of interface between the machine and the patient. A tube placed in the trachea is often used as the patient interface for invasive gas delivery. Use some form of mask as the patient interface when delivering air non-invasively. [0003] Masks typically include a chamber with a nose-receiving cavity formed by an outer shell or frame. The mask typically also includes a portion that comfortably contacts the face, such as a cushion, that is secured to the edge of the shell or frame. The mask is typically held in place on the patient's face by headgear, such as a set of elastic straps. Improving the comfort of a mask, especially when t...
