PROBLEM TO BE SOLVED: To resolve drawbacks that known respiration aid devices have.SOLUTION: In a ventilator for supplying pressure respiratory gas which is equipped with an inlet and an outlet for the respiratory gas and a rotor rotationally driven by a motor, the outlet arranged so as to discharge breathing pressure gas in a direction substantially parallel to the rotation axis of the rotor includes a convergent part where flux generated by the rotor is caused to be focused in an oblique direction with respect to the rotation axis, and a rectification part which is arranged downstream of the convergent part and causes the flux discharged from the ventilator to be oriented toward a direction substantially parallel to the rotation axis of the rotor. |
