Abstract:
1. An oxygen therapy humidification device for humidifying gas delivered to a patient, the device comprising: a hollow water reservoir that includes an upper end that has an upper cross-sectional area and a lower end having a lower cross-sectional area; an oxygen inlet and an oxygen outlet positioned at the upper end of the hollow water reservoir and providing fluid communication into the hollow water reservoir, the oxygen inlet having a bypass valve that is connected to a duct that extends from the oxygen inlet to the lower end of the hollow water reservoir, the bypass valve comprising a needle valve that uses a needle that adjustably extends into the inlet duct to allow the user to control humidification by controlling the proportion of oxygen delivered through the bypass valve and then delivered to the duct and into the hollow reservoir where it is allowed to remix with oxygen that was delivered to the hollow water reservoir, so that the remixed oxygen is then allowed to escape the hollow reservoir through the oxygen outlet.
