Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to a wall-plug oxygen inhaler. Background technique

[0002] The currently used wall-plug oxygen inhaler includes a cup, a flow meter, a connector, a filter ferrule and a humidification bottle, and the connector is provided with an oxygen supply chamber interface, a flow adjustment knob and an oxygen tube interface. The oxygen tube interface is along the radial direction of the connector. When in use, the oxygen tube is connected to it and bends downward, which may easily lead to pressure suppression and accidents, and the oxygen flow is not smooth, which affects the treatment effect. The flow meter generally adopts a buoy flow meter. In addition, an air outlet passage inclined relative to the axial direction is provided along the axial direction of the connector, the inlet of the air outlet passage is arranged at the bottom of the thread groove at the upper end of the co...
