PURPOSE: A humidification device combined with an oxygen flow meter is provided to always supply oxygen having a high percentage of humidity to a patient requiring the oxygen inhalation treatment. CONSTITUTION: A humidification device combined with an oxygen flow meter consists of a flow meter part(A) and a humidifier part(B). The flow meter part comprises a flow rate gauge(1), a gauge cover(2), a body(3), a flow rate regulator(4), and an adaptor(5). The humidifier part comprises a connector(6), a bubble jet switching lever(7), a safety valve(8), a humidification container(9), a siphon tube(10), a diffuser(11), and an outlet(12). As the bubble jet switching lever is rotated in left and right directions, an opening and closing valve is actuated, and an opening and closing ball stacked on a spring opens and closes the lower part of a nozzle tip. In this way, the humidification device selectively uses a bubble mode and a jet mode by applying a venturi tube, thereby the oxygen of appropriate humidity being supplied to a patient according to the condition of the patient.
