The positive airway pressure respirator comprises a noninvasive positive airway pressure respirator and an invasive positive airway pressure respirator. Among them, the noninvasive positive airway pressure respirator can only play a limited role in assisting respiration, and is only used for patients with partial mild or moderate respiratory dysfunction. For patients with moderate-severe respiratory dysfunction, such as patients with impaired respiratory center (e.g. patients with partial stroke and traumatic brain injury), patients with severe respiratory myasthenia (e.g. patients with myasthenia gravis and neuromuscular junction disease), and patients with other pulmonary diseases (e.g. patients with new coronary pneumonia, patients with severe bacterial infectious pneumonia, and patients with acute exacerbation of chronic obstructive pulmonary disease), invasive positive airway pressure ventilators are widely used for treatment.

9. The pleural cavity negative pressure ventilation respirator of claim 8, characterized in that the air bag (212) is a circular cylinder structure with a circular section, and the air inlet nozzle of the air bag (212) is positioned on the circular end surface of the air bag and is connected with one end of the conduit (211) far away from the air vent; a central tube (215) with two ends penetrating and used for placing a metal soft guide wire is arranged in the ring of the air bag (212) in a penetrating mode, air holes used for injecting air and exhausting air into the pleural cavity are formed in the side wall of one end, far away from the air inlet nozzle, of the central tube (215), and a closing piece (216) used for closing the end portion of the central tube (215) is detachably connected to the other end of the central tube.
10. The negative pressure pleural cavity ventilation ventilator of claim 4 or 5, further comprising a carbon dioxide detection mask and an ear clip blood oxygen detection assembly disposed outside the case (11), and both the carbon dioxide detection mask and the ear clip blood oxygen detection assembly are connected to the control member.
11. The pleural cavity negative pressure ventilation breathing machine according to claim 4 or 5, further comprising a chest wall breathing movement detection assembly disposed outside the cabinet (11) for detecting chest wall expansion movement of a human body, and the chest wall breathing movement detection assembly is connected with the control member.
12. A method of using a pleural cavity negative pressure ventilation ventilator, the method being applied to a pleural cavity negative pressure ventilation ventilator of any one of claims 1-11; the method comprises the following steps:
s1: puncturing the pleural cavity of a human body by using a thoracic cavity puncturing assembly and forming a puncturing wound;
s2: extending one end of the ventilation piece (2) far away from the ventilation opening into the pleural cavity from the puncture wound;
s3: and starting the respirator body (1), wherein the respirator body (1) injects air and extracts air to the air ventilating piece (2) so as to change the pressure in the pleural cavity and further realize the collapse and expansion of the lung.
