Discuss the Risk of the Ventilator and Evaluate the Effect of Ozone Disinfection

Abstract

<i>Objective: </i>To understand the possibility of nosocomial risk in the internal pipeline of the ventilator, and to discuss the necessity of disinfection of the internal pipeline by comparing the total number of colonies in the experimental sampling pipeline. <i>Methods:</i> It is innovatively proposed to put the ventilator in a cubic confined space, and start the ventilator in the running state. For the first time, ozone gas is used for the ventilator to smoke the whole process of the ventilator, and design the prototype of the whole process of the ventilator pipeline disinfection machine. <i>Results:</i> by sampling the ventilator intake, outlet total colonies before disinfection and disinfection, with reference to health standards, test results show that the ventilator before disinfection internal management total colonies overweight phenomenon, the total number of bacterial colonies after disinfection detection results within the health standard, according to the statistical method analysis P value is 0, think the bacterial colonies before and after the ventilator disinfection have significant differences. <i>Conclusion: </i>The test result proves that the number of bacteria is lower than the standard value of 20, and the disinfection method has obvious effect. The internal pipe of the ventilator has the risk of hospital sensation. The disinfection method of ozone smoke is effective and safe, and the market needs the product of a ventilator.
