PURPOSE:To provide an extremely novel simplified oxygen supply device which is favorable in portability and which capable of supplying safe and secure breathing air simultaneously by using a small quantity of compressed oxygen and discharged air of breathing by a user more effectively to provide new air for breathing. CONSTITUTION:A takeout metal 2 is installed on an oxygen taking-out port 11 of a compact pressure-proof container 1 in the which high-concentration compressed oxygen is filled. A mask to be installed on a face is connected through an air feed tube 4. An agitation and mixing pat 5a to mix supply oxygen from the pressure-proof container 1 with discharge air of breathing by a user is provided at the mask 5.; Discharging quantity of oxygen by the takeout metal 2 is set in such a way that supply oxygen and discharge air of breathing agitated and mixed in the agitation and mixing part 5a generate new breathing air including oxygen at an equivalent ratio to that in open air. A supply air blow port 6 comprising a porous member is formed in the agitation and mixing part 5a. Agitation and mixing material 7 comprising porous fibers is charged to surround the oxygen blow port 6. |
