呼吸机湿化罐开启方法的改进与应用

Improvement and application of the opening method of mechanical ventilator humidification tank liquid

目的改进湿化罐开启的方法，提高湿化罐开启的效率与成功率。方法2015年5月1日至10月31日回收的临床科室所有呼吸机湿化罐为对照组，2016年2月1日至7月31日回收的临床科室所有呼吸机湿化罐为试验组，对照组采用金属工具方式开启，试验组采用研发改进的湿化罐开启装置进行开启，比较2组的呼吸机湿化罐破损率。结果采用研制的实用型呼吸机湿化罐开启装置，呼吸机湿化罐损坏率由使用开启装置前5．97％（16／268），降低至1．22％（3/245），降幅达79．56％，改善前后比较差异有统计学意义（X2=8．082，P〈0．01）。结论呼吸机湿化罐改进开启装置的应用，显著提高了湿化罐开启的完好率，大大提高了工作效率，节约了成本。

Objective To improve the opening method of humidifier, enhance the efficiency and success rate of opening the humidifiers. Methods Use all the recycled humidifier from respirators in the wards from 1st of May to 31st of October 2015 as control group. Use the recycled humidifiers from 1st Feb to 31st July 2016 as the test group. Use metal tools to open humidifier bottles in the control group while use the newly developed and improved opening device to open the bottles in the test group to test and compare the damage rate. Results The testing group that used the practical opening device for humidifier has a decrease in damage rate from 5.97% （16/268） to 1.22% （3/245）, and this difference before and after was statistically significant （X2= 8.082, P〈0.01）. Conclusions The use of the opening device for humidifier can enhance the intact rate, greatly improve working efficiency and save the cost.
