[Design and application of the improved atomized airway humidifier]

Airway humidification is an important treatment for tracheotomy patients. At present, the commonly used methods of humidification are atomization inhalation, intra-tracheal drip, etc., but most of them have the disadvantages of interrupted humidification, inadequate humidification, repeated exposure of airway, increased nursing workload, etc. An improved disposable atomizer was designed by the emergency department of Jiaxing First Hospital in Zhejiang Province, which solved the above problems and obtained the National Utility Model Patent of China (ZL 2014 2 0406688.9). In the traditional atomizer, a make-up pipeline is added to run through the liquid container. The replenishing pipe is connected with an external infusion device. At the end of the pipeline inside the liquid container, a buoy with a guide rod is designed to continuously add liquid and automatically control the make-up speed. The device is driven by oxygen to perform airway humidification. The design can keep sufficient airway humidification, avoid frequent addition of humidification fluid, achieve the effect of increasing humidification, reducing the occurrence of complications, increasing the comfort of patients, and reducing the workload of nursing, and has a certain clinical value.
