なかった。In any case, there are decisive problems that there is a loss of gas, the absorption efficiency is poor, the structure is complicated, the cost is high, and the user has no sense of reality. In addition, the simple oxygenator used especially in sports has a problem of decisive "difficulty in use" in that both hands cannot be used during valve operation etc. before use. That is, there was no choice but to use (inhale) “before” or “after” when it was supposed to be used.

全に解放する。The check valve 3 can be attached to the tube 9 by any suitable method such as press fitting, adhesion with an adhesive, or welding so long as it can prevent gas leakage. The check valve 3 is normally closed, and when the tube 9 is bitten from the outside in the axial direction by the mouth, the check valve 3 is opened and oxygen gas flows out. Therefore, when the oxygen gas is needed, the tube 9 may be bitten, and the check valve 3 is not opened unless it is bited, so that impurities are not mixed in from the outside and the oxygen gas does not flow out to the outside. No hand movements are required to operate the valve, completely freeing both hands from breathing work.

クは皆無であった。[Example] Using sports oxygen, which is a product of the applicant company and whose name is also a registered trademark, a PVC tube (internal diameter 4φ) with an outer diameter 4φ of the same material is used for the gas outlet to which a conventional mask is attached The non-return valve prototyped in 1. was inserted inside and bonded, and the outside of the tube was fitted and bonded with a protrusion (end sleeve) having an inner diameter of 6φ. The oxygen pressure was set to 2 kgf / cm 2 and the flow rate was set to 1-2 l / min. As a result, the check valve worked, gas did not flow at all, and there was no leak.

果も発揮できる。Next, the tube was bitten in the mouth and lightly bitten with the teeth, so that the same amount of gas was reliably supplied. When he stopped biting, the check valve closed completely. At the same flow rate, there was a feeling of being able to absorb a larger amount of oxygen than when using a conventional mask. This is also theoretically proven by keeping the air tightness in the mouth with the lips and not entraining the surrounding air as in the case of a mask. In addition, this check valve is ideal for sanitary conditions in the tube because it is free from contamination by external foreign matter and its contamination. It can also exert an oxygen bacteriostatic effect in the mouth.
