Claims

[Scope of utility model registration request]

In a portable oxygen auxiliary device that supplies oxygen using a small cylinder 2 that has a sealing plate 4 in the opening 3 and that is filled with oxygen, the sealing plate of the cylinder 2 is attached to the auxiliary main body 1 to which the cylinder 2 is attached. A seal breaking mechanism 5 that breaks the seal 4 and blows out oxygen, and a flow rate control mechanism 6 that automatically controls the flow rate of the squirted oxygen to a constant level are provided, and between the seal breaking mechanism 5 and the flow rate control mechanism 6. A portable oxygen auxiliary device characterized in that a manual piston valve 7 is provided which opens and closes an oxygen flow path by sliding in both directions.
