Fig. 1 is a longitudinal sectional view of a breathing bag according to the present invention, and Fig. 2 is a sectional view taken along line I in Fig. 1. It is an elastic bag body, and the bag body 1 is made of a resilient material that restores itself by self-expansion.One end of the bag body 1 has an air intake port 3.
Furthermore, an exhaust port 4 is formed at the other end.
The bag body 1 of the embodiment is made up of an inner bag 1a made of sponge material, covered with a thin outer bag 1b made of rubber, and one end of the inner bag 1a is equipped with a fitting port tube made of rubber and provided with an intake port 3. 5 is fixed by adhesive or the like, and a fitting port tube 6 made of rubber and provided with an exhaust port 4 is fixed to the other end by adhesive or the like. In this case, the elastic bag main body 1 includes an inner bag 1a, an outer bag 1b, and fitting opening pipes 5, 6.
It can be formed into one piece including
Examples include vinyl and silicone rubber.

It is divided into 2b. In the embodiment, a constriction is formed approximately in the center of the bag body 1, and the storage chamber 2 is divided by approximately 2 minutes (50:50).
For example,
The volume of the storage chamber 2 can be divided as desired, such as 40:60 or 30:70.

ク１１へ供給される。 The present invention is constructed as described above, and its usage and effects will be explained below. As shown in the first figure, the intake valve 8 is fitted into the intake port 3, and the exhaust valve 10 is fitted into the exhaust port 4. Then, by compressing the bag body 1 (at this time, the valve 8 is closed and the valve 10 is opened), the gas storage chamber 2 is compressed.
By supplying the gas inside to the breathing mask 11 and releasing the compression, the bag body 1 self-inflates (at this time, valve 9 closes and valve 8 opens),
Gas is sucked into the chamber 2. Therefore,
Now, if the entire bag body 1 is compressed, all of the gas in chambers 2a and 2b, that is, in chamber 2, will be supplied to the respiratory mask 11, and by compressing only the chamber 2a side, the gas in chamber 2a will be supplied to the respiratory mask 11. Only gas is mask 1
Further, by compressing only the chamber 2b side, the volume of gas in the chamber 2b is supplied to the mask 11.
