Abstract: A ventilation treatment device and a ventilation-control method are provided. During use, when a headband contacts a headrest, a first valve assembly contacts a second valve assembly to open first air holes and second air holes, thereby communicating a first chamber with a second chamber, such that air from an air source into the first chamber enters the second chamber and further enters a respiratory chamber of a patient connecting apparatus for inhalation by a patient; and when the headband is separated from the headrest, the first valve assembly and the second value assembly are separated to close the first air holes and the second air holes, thereby preventing the air in the first chamber and the second chamber from flowing out through the first air holes and the second air holes, respectively.

Abstract: A tube assembly includes a first tube piece and a second tube piece. The first tube piece includes an inlet end connecting a gas source and an outlet end connecting the second tube piece. The first tube piece includes a discharging hole that is configured so that, in a connecting state, the discharging hole is closed to make the gas to enter the second tube piece, in the separating state, the discharging hole is opened to make the gas to be discharged outside from the discharging hole. The tube assembly includes a valve member that is configured so that, in the connecting state, the valve member opens the outlet end of the first tube piece to make the gas to enter the second tube piece, and in the separating state, the valve member closes the outlet end to make the gas to be discharged outside from the discharging hole.
