ABSTRACT
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 (χ2=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.
