The utility model has a simple structure and is easy to use. Through the coordinated design of the mask body, the nasal mask and the fixing assembly, the problem of the existing non-invasive ventilator mask having a large pressure binding force during use, which is prone to pressure sores and air leakage, is solved. The pressure binding force is reduced while ensuring continuous positive airway pressure ventilation, thereby increasing the patient's comfort. At the same time, a nasal mask is provided in the mask body, which can greatly improve the patient's oxygen absorption efficiency and effect.

[0004] The above-mentioned device is not provided with components that can facilitate the patient to place a gastric tube and drink water. Therefore, when the patient needs to place a gastric tube and drink water, the mask needs to be disassembled, which seriously affects the airtightness of the non-invasive ventilator during use, causing air leakage and affecting the patient's blood oxygen saturation. The airtightness is poor. Therefore, an improved non-invasive ventilator positive pressure nasal mask is proposed to address the above problems. Utility Model Content

[0014] 1. The utility model realizes the function of facilitating the patient to place a gastric tube and drink water while ensuring airtightness through the structural design of a convenient sealing mechanism, and solves the problem that the existing device is not provided with a component that facilitates the patient to place a gastric tube and drink water, so that when the patient needs to place a gastric tube and drink water, the mask needs to be disassembled, which seriously affects the airtightness of the non-invasive ventilator during use, resulting in air leakage affecting the patient's blood oxygen saturation and poor airtightness, thereby improving the airtightness;

[0015] 2. The utility model realizes the function of absorbing condensed water at the bottom of the mask through the structural design of absorbent cotton, which solves the problem that since patients with non-invasive ventilators need to humidify their airways and use masks for a long time, condensed water will accumulate at the bottom of the mask. Excessive condensed water will cause long-term infiltration of the patient's facial skin, which is easy to cause skin damage and reduce the patient's comfort level due to long-term moisture. In severe cases, condensed water will return to the airway through the oral and nasal cavities, causing choking and aspiration, thereby improving the protection of patients.
