Abstract
Abstract Lightweight, compact, attractive, reliable and convenient to use carrying cases for replaceable oxygen generating cells or candles having mechanism for activating or igniting the cells or candles for delivering oxygen through a carrying strap to a canula or breathing mask. The carrying cases of this invention are suspended from a strap also serving as an oxygen conduit and are worn in the manner of a binoculars case to supply instant oxygen when needed by the wearer. These carrying cases with their replaceable oxygen generators or candles release heart and emphysema patients from heretofore required confinement to the vicinity of large heavy oxygen bottles.
