Abstract

A disposable anesthesia mask is provided which has a top portion having an aperture, an encompassed side portion and an open bottom portion. Located on the open bottom portion is an inflatable sealing means, which provides a pneumatic seal between the mask and the patients face. The disposable mask is transparent and is located around the nasal bridge. This shape alleviates orbital pressure. Elongated hooks that are attached to the mask by a head strap plate provides the option of affixing a strap to the mask.
