Analysis and Discussion of AF-A Low-noise Bacteria-resistant Oxygen Device and Traditional Oxygen-humidified Bottles

OBJECTIVE To explore the methods of the traditional bottle of oxygen-humidified bottles leading to the nosocomial infection,and to choose a safe and effective oxygen facilities of controlling hospital infection.METHODS Sputum culture was conducted for 51 respiratory tract infection patients with nosocomial infections,among which,the bacteriological culture of all parts of traditional oxygen-humidified bottles therapy were taken.Meanwhile the samples of bacteriological culture were collected from 98 cases of using a disposable AF-A low-noise bacteria-resistance-type oxygen therapy device after 1-6 days.RESULTS A total of 51 cases of nosocomial infected patients who used traditional oxygen-humidified bottles of bacterial culture showed the same symptoms as those who suffered from the sputum culture.Sputum culture was detected out Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli,acetic acid bacteria Acinetobacter baumannii spectrum whose constituent ratio were 21.43%,21.43%,10.71% and 3.57%,respectively.From humidifier-bottle P.aeruginosa,K.pneumoniae,Escherichia coli,acetic acid bacteria A.baumannii spectrum were detected whose constituent ratio were 34.78%,21.74%,8.69% and 13.05%,respectively.And no bacterial growth was found in AF-A low-noise bacteria-resistantce-type oxygen therapy devices within 4 days,the safe use period was 5 days.CONCLUSION The traditional oxygen-humidified bottles are susceptible to the bacterial contamination,which results in the risky factors of nosocomial infection,while the disposable AF-A low-noise bacteria-resistantce-type oxygen therapy devices can prevent the nosocomial infection caused by the contamination of oxygen humidified bottles.
