Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to an integrated ventilator. Background Art

[0002] The use of home-use ventilators is becoming more and more common. A ventilator is an artificial mechanical ventilation device used to assist or control the patient's spontaneous breathing movements to achieve the function of gas exchange in the lungs, reduce the body's consumption, and facilitate the recovery of respiratory function. The principle of using a ventilator to treat patients with poor lung function, lung failure, and sleep apnea syndrome is as follows: the ventilator generates appropriate continuous positive pressure ventilation (including constant positive pressure, variable positive pressure, etc.), which is provided to the patient through a nasal mask or an oronasal mask, which can effectively prevent the patient's airway from collapsing or partially collapsing, thereby ensuring that the patient can breathe smoothly. The ventilator used to treat breathing disorders caused by poor lung function, lung failure, sleep apnea syndrome, etc. is a bi-level ventilator. The concept of a bi-level ventilator is to provide the patient with a set higher inspiratory pressure and a lower expiratory pressure, which are automatically switched during the patient's breathing process.

[0003] The actual application functions of existing ventilators are relatively simple. At the same time, the noise reduction effect during use needs to be improved. The overall intelligence level is insufficient, and the actual usage experience needs to be improved. Utility Model Content
