The present invention relates to an oxygen-controllable underwater breathing device using a hollow fiber. In a breathing device for providing breathing gas to a user, the oxygen-controllable underwater breathing device using a hollow fiber according to the present invention comprises: an exchange part formed of a hollow fiber to make gas exchange using the concentration difference between breathing gas caused after a user breathes and underwater dissolved oxygen; a filter part formed of the hollow fiber containing magnetic particles, and mixing the underwater dissolved oxygen with the breathing gas generated by the exchange part after filtering the underwater dissolved oxygen; and a supply part for supplying the breathing gas passing the exchange part to the user. Thus, the present invention can control the concentration of the oxygen contained in the gas, which is supplied to the user, using the hollow fiber modules having different characteristics. |
