摘　　要：目的 研制一种新型的呼吸机湿化器自动加水装置.方法 利用输液器挂高后的重力持续加水,以传感器检测液面高度作为信号,通过电磁阀控制输液器皮管外套截止夹的关闭和开启.结果 当呼吸机湿化器内液面低于设置值时,输液器截止夹打开,输液瓶内的纯净水自动加入湿化器内;当湿化器内液面达到设置的液面高位时,截止夹受控关闭,停止加水.结论 此呼吸机湿化器自动加水装置工作有效、使用方便,实现了持续、相对匀速、少量的稳态加水过程;同时,湿化器内水量稳定,加热均匀,进入呼吸道的气体温度相对恒定,可以在临床推广使用.Objective To develop a novel automatic water system for ventilator humidifier. Methods By hanging the infusion apparatus high, sustained water was filled by driving force of gravity. Liquid level in the thong of the infusion apparatus was detected by the sensor, and the closing and opening of the closing clip was controlled by solenoid valve. Results The closing clip opened when the liquid level inside the ventilator humidifier fell below the lowest setting value and purified water in the infusion bottle automatically flowed to the humidifier. When the liquid level reached the highest setting level, the closing clip was automatically closed. Conclusions The developed automatic water system fur ventilator humidifier is effective, convenient, inexpensive, and realized a sustained, relatively steady and a small amount of water process. Meanwhile, humidifier water is stable, heating is uniform, and gas temperature is relatively constant, which can be applied in clinical use.
