ABSTRACT:
An oxygen therapy humidification device is disclosed. The humidification device includes a hollow water reservoir that includes an upper end that has an upper cross-sectional area and a lower end that has a lower cross-sectional area. The lower cross-sectional area is smaller than the upper cross-sectional area. The device also includes an oxygen inlet and an oxygen outlet, both of which are positioned at the upper end of the hollow water reservoir and provide fluid communication to and from the hollow water reservoir. The oxygen inlet includes a bypass valve that is connected to a duct that extends from the oxygen inlet to a diffuser that is positioned at the lower end of the hollow water reservoir. The bypass valve allows the user to control the proportion of water vapor or humidity delivered to oxygen that is passed through the device, with the oxygen entering through the inlet and leaving through the outlet at the desired humidity level.
