摘要
目的研究医院中心供氧系统终端细菌污染的情况与使用MX-1型灭菌消毒器的消毒效果。方法通过24h供氧过程中对供氧终端装置(氧气流量表、湿化瓶、吸氧导管等)的定时多点采样进行细菌定量培养。结果5个的定时多点采样研究证明,大连医科大学附属第二医院呼吸病房中心供氧管道输送的氧气及在供氧过程中经严格消毒后的终端装置均无细菌污染现象,如终端装置未严格执行消毒措施则可出现严重的细菌污染;试验结果发现,氧气流量表湿化瓶瓶盖、砂石是细菌污染的主要来源,若在终端连接MX-1型灭菌消毒器可以消除细菌污染。结论进行氧疗时,供氧装置倘若消毒不严格,会造成严重细菌污染;而在终端连接MX-1型灭菌消毒器可有效消除供氧装置终端细菌污染,保证氧气清洁与安全。
OBJECTIVE To investigate the terminal bacterial pollution of hospital central oxygen supply system and the sanitizing effect of MX-1 disinfector. METHODS Timing many spot samples of terminal oxygen supply equipment （oxygen flowmeter, humid bottle, oxygen pipe） were quantified and cultivated through 24 hours continue supply. RESULTS Five cases of timing many spot samples testified that there were no bacteria oxygen pollution in the pipe oxygen supply in the Department of Respiratory Disease, the Second Affiliated Hospital of Dalian Medical University, and that there were no bacteria pollution in the terminal oxygen supply equipments if they were sterilized strictly, but there would be severe bacteria pollution if they were not sterilized strictly. This test found that lid of humid bottle and lapis were the main source of bacteria pollution. Connection with MX-1 disinfector in the terminal can avoid bacteria pollution. CONCLUSIONS Severe bacteria pollution will happen if the oxygen supply equipments aren＇t sterilized strictly; connection with MX-1 disinfector in the terminal can avoid bacteria pollution and ensure oxygen for cleanliness and safety.
