超声波雾化器雾气倒灌是雾化器锈蚀的主要原因,它将大大降低了其使用寿命。我们根据可控同步呼吸机KTH-2型中的呼吸活辦结构原理对雾化器略加改装,即可解决雾气倒灌问题,其方法将呼吸活瓣连接于送雾管与咬嘴(有的用呼吸面罩)中间。当病人吸气时,吸力把前吸气活瓣打开,药雾被病人吸入,而当病人呼气时 Ultrasonic nebulizer mist reversal is the main cause of atomizer corrosion, which will greatly reduce its service life. We modified the nebulizer slightly according to the principle of the respiration mechanism in the controllable synchronous ventilator KTH-2 to solve the problem of fog inversion. The method connects the respiration valve to the mist-feeding tube and the mouthpiece (some Use breathing mask) in the middle. When the patient inhales, the suction opens the front inhalation valve and the inhalation of the drug mist occurs when the patient exhales
