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: An exhaust assembly, a ventilation assembly, a frame assembly and a mask system. When the mask system is worn, the nostrils and the mouth of a user are respectively covered by means of a nose structural body and a mouth structural body, which can meet the requirement of mouth breathing and thus has the advantage of good clinical blood gas parameters. Since the mask system seals around the nostrils of the user and thus avoids pressing the bridge of nose or two sides of the wing of nose of the user, the mask system has a smaller and lighter structure and better visibility, and thus has improved comfort. Compared with a full-face mask, the nasal mask is not prone to feeling claustrophobic and has better compatibility for people. The mask system can improve the treatment effect and treatment compliance.
