Abstract
Abstract An exhalation dispersing apparatus for use in a water medium comprising a bag adapted to fit and be secured to one end of a container pack which houses cylinders of breathing gas and accessory equipment. The bag comprises substantially coextensive inner and outer liners sealed together along their marginal edges and also along transverse portions thereof to form a plurality of longitudinally spaced dispersing chambers. Cross flow passages are provided between adjacent chambers. A pair of exhalation conduits are connected from a breathing apparatus to the dispersing bag and a plurality of closely spaced, self-sealing apertures are formed over substantially the entire outer liner for dispersing the exhaled gas from the chambers into the ambient water in the form of minute bubbles.
