Abstract
Official abstract text for this publication.
A mask assembly includes a mask with an inflatable bladder. The internal pressure of the inflatable bladder can be set to be higher than the delivered therapeutic pressure. The pressure offset may be constant, or it may vary over the range of therapeutic pressures. Thus, the force necessary to maintain a contact seal between the mask and the patient can be reduced, thereby providing a system that is more comfortable to the patient, which increases patient compliance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A patient interface comprising: a frame; a cushion provided to the frame and defining a chamber structured to be in communication with a first source that is adapted to provide a first pressure to the chamber; and a bladder associated with the cushion and configured to engage a face of a patient, the bladder having a side wall, and the side wall being thinner in a face contacting region of the bladder than in a face non-contacting region, the side…
