摘要

PROBLEM TO BE SOLVED: To prevent outside air from flowing in from an exhaust end part. SOLUTION: This respirator 12 adopts a high frequency vibrating ventilation method of energizing higher frequency vibrating air pressure than the respiration cycle of a patient P, to oxygen to be supplied to a patient to perform oxygen inhalation and exhalation. In this case, an exhaust path for exhausting exhalation from the patient P into the atmosphere is equipped with an exhaust direction regulating mechanism 7 for regulating the flow direction of exhalation into a fixed exhaust direction.
