a main body having a gas discharge provided at a front side to discharge a gas externally;
a handle that extends from the main body; and
a concentrator detachably coupled to the main body and externally discharging the gas discharged from the gas discharge, the concentrator comprising:
an outer case forming an exterior of the concentrator and provided with a first flow path and a second flow path therein through which the gas discharged from the gas discharge flows; and
a flow path selector a position of which is variable within the outer case, wherein the first flow path is provided between the flow path selector and the outer case, wherein the second flow path is provided within the flow path selector, wherein the outer case further comprises a flow path selecting space in front of the gas discharge outside of the flow path selector through which gas flows from the gas discharge, wherein the flow path selecting space is opened forward and constantly communicates with the first flow path, and selectively communicates with the second flow path in a radial direction of the flow path selector depending on the position of the flow path selector, and wherein the concentrator selectively selects either the first flow path or the second flow path depending on a location of the flow path selector.
