改良型一次性雾化器的设计和应用方法

Design and application of the improved atomized airway humidifier

气道湿化是气管切开患者的主要治疗方法。目前常用的湿化方法有雾化吸入、气道内滴注等,但大多存在湿化中断、湿化不充分、反复暴露气道、增加护理工作量等缺点。浙江省嘉兴市第一医院急诊科设计了一种改良型一次性雾化器,解决了上述问题,并获得国家实用新型专利(专利号:ZL 201420406688.9)。该装置在传统雾化器的贮液器上增加了一个与贮液器贯通的补液管,该补液管与外接的输液装置相连;同时在贮液器内的补液管末端设计了一个带导向杆的浮标,通过浮标的浮力作用来自动控制补液。该装置由氧气驱动,实现气道湿化。一次性雾化器可实现持续充分的气道湿化,避免频繁添加湿化液造成反复暴露气道,达到提高湿化效果、减少并发症、增加患者舒适性、减少护理工作量的目的,具有一定的临床应用价值。

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 201420406688.9).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.
