Title:
REBREATHER VEST
Document Type and Number:
WIPO Patent Application WO/2012/026989
Kind Code:
A3
Abstract:
A closed circuit rebreather uses a vest (10) with an air tight internal cavity (26) that has a channel (30) therein, the channel (30) passing through a series of passageways (26) that are each either generally unidirectional or at least some weave back and forth and either on a single layer or a double layer. Located throughout the length of the channel (30) is a C02 scrubbing material (34). A person exhales which causes the exhaled breath to enter one end of the channel (30) and pass through the channel (30) while being scrubbed of C02 and when the user inhales, fully scrubbed air (A) is drawn from the opposing end of the channel (30). Appropriate spacers, either V-shaped separators (82) or ribs (88) of various designs can be used to hold the channel (30) open.
