为了提升病人戴面罩的舒服性同时避免气体从罩体1边缘与病人面部之间逸出，如图1和图2所示，所述罩体1的周向边缘内侧设有硅胶密封圈9。In order to improve the comfort of the patient wearing the mask and prevent gas from escaping between the edge of the mask body 1 and the patient's face, as shown in Figures 1 and 2 , a silicone sealing ring 9 is provided on the inner side of the peripheral edge of the mask body 1 .
本发明通过在罩体上的进气管上设置三通管接头和控制阀，三通管接头连接输气管和雾化管，通过在进气口下方设置排痰口，排痰管与排痰口可拆卸连接，同时排痰口附近设置有封盖，使得在无创呼吸机输气的过程中输入雾化液，能够对气体进行进一步地湿化，同时雾化药液被病人吸入后能够湿化肺部的痰液，便于痰液的排出，痰液从吸痰管吸出，使用方便。In the present invention, a three-way pipe joint and a control valve are arranged on the air inlet pipe on the cover body, and the three-way pipe joint is connected to the air delivery pipe and the atomization pipe, and a sputum discharge port is arranged below the air inlet, and the sputum discharge pipe and the sputum discharge port are arranged. Removable connection, and a cover is set near the expectoration port, so that the atomized liquid can be input during the gas infusion process of the non-invasive ventilator, which can further humidify the gas, and at the same time, the atomized liquid can be humidified after being inhaled by the patient The sputum in the lungs is convenient for the discharge of sputum, and the sputum is sucked out from the sputum suction tube, which is convenient to use.
以上公开的仅为本发明的几个具体实施例，但是，本发明实施例并非局限于此，任何本领域的技术人员能思之的变化都应落入本发明的保护范围。The above disclosures are only a few specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
