Abstract
A respirator package for carrying on a person includes a tubular frame which forms a container for a high pressure gas such as oxygen. A respiratory air circulating system is adapted to be mounted on the frame and connected to the high pressure gas therein for the selected circulation of the gas and respiratory air to and from the wearer and also advantageously includes means for regenerating the breathing air and supplementing it with the gas such as oxygen. The high pressure gas container comprises a frame made up of successive windings of a tube to form a closed container having a connecting valve associated therewith. The frame thus formed is advantageously provided with straps so that the frame can be carried on a wearer's back and it provides a spacing and insulation for a breathing system which advantageously includes a regenerator which is likely to heat during operation. The parts of the system are held in place on the frame by means of a casing which is secured to the frame.
