<P>PROBLEM TO BE SOLVED: To provide a respiratory assistance device which resolves a drawback that a heretofore known respiratory assistance device has. <P>SOLUTION: In a ventilator for the supply of pressure respiratory gas having the entrance and outlet of the respiratory gas and a rotor which is arranged so that it is rotated and driven by a motor, the outlet is arranged so that the pressure respiratory gas to leave is discharged in a direction which is substantially parallel to the axis of rotation of the rotor, and the outlet has a convergent part where flux generated by the rotor is arranged so that it focused in an oblique direction to this axis of rotation and a rectification part which arranged downstream of the convergent part and makes the flux which comes out of the ventilator head in the direction which is substantially parallel to the axis of rotation of the rotor. <P>COPYRIGHT: (C)2011,JPO&INPIT |
