Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a high-flow oxygen therapy humidification device. Background Technology

[0002] Oxygen therapy refers to the treatment of various types of hypoxia. Besides eliminating the cause of hypoxia, oxygen therapy can be administered. By inhaling high concentrations of oxygen, the dissolved oxygen content in the blood plasma increases, improving tissue oxygenation and reducing insufficient or impaired tissue oxygen utilization caused by hypoxia, thus preventing a series of pathological changes that alter bodily functions, metabolism, and even morphological structures.

[0003] Because existing oxygen therapy devices provide excessively dry oxygen, patients experience discomfort during treatment due to inhaling this dry oxygen, leading them to refuse oxygen therapy and thus reducing its effectiveness. Therefore, a high-flow-rate oxygen therapy humidification device is needed. Utility Model Content

The humidified oxygen also moistens the alveoli, increasing their activity and facilitating gas exchange.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-flow oxygen therapy humidification device includes a humidification mechanism and an oxygen flow meter. The oxygen flow meter is located at the upper end of the humidification mechanism and is equipped with a quick-connect connector and a flow adjustment knob.

[0011] Furthermore, the pagoda connector includes a cylinder and an air inlet pipe. The cylinder is a hollow cylinder with a sealed upper end and an open lower end. The lower end of the cylinder passes through the upper cover and extends to the upper part of the lower cover. The lower end of the air inlet pipe passes through the upper end of the cylinder and extends to the middle of the cylinder.

[0012] Furthermore, the upper end of the cylinder is provided with an oxygen concentration regulating port, which is shaped like a spoon, and the upper side of the oxygen concentration regulating port is provided with a first annular groove.
