【摘要】:目的觀察自行研制的口腔綜合治療臺(tái)水路系統(tǒng)臭氧水消毒機(jī)的消毒效果,探索最優(yōu)消毒方案。方法使用臭氧水消毒機(jī)生成約2mg/L濃度的臭氧水對(duì)14臺(tái)口腔綜合治療臺(tái)水路系統(tǒng)進(jìn)行沖洗消毒,分別采集消毒前及消毒1、3、5、10min后手機(jī)出水口水樣,經(jīng)37℃、48h培養(yǎng)后觀察計(jì)菌落數(shù),采用SPSS軟件進(jìn)行統(tǒng)計(jì)分析。結(jié)果口腔綜合治療臺(tái)水路系統(tǒng)污染嚴(yán)重,消毒前手機(jī)出水水樣菌落數(shù)達(dá)(2336±837)CFU/ml;各消毒組水樣菌落數(shù)與消毒前相比差異均有統(tǒng)計(jì)學(xué)意義(P0.01),對(duì)細(xì)菌滅活率在沖洗消毒1min后達(dá)到92.98%,并隨沖洗時(shí)間延長(zhǎng)而提高,沖洗5min后各消毒組間差異無(wú)統(tǒng)計(jì)學(xué)意義,沖洗10min后對(duì)細(xì)菌滅活率達(dá)99.57%。結(jié)論臭氧水消毒高效可靠,可代替常用的次氯酸鈉消毒劑沖洗消毒口腔綜合治療臺(tái)水路系統(tǒng),2mg/L濃度的臭氧水作用3~5min可達(dá)到最佳效果。
[Abstract]:Objective to observe the disinfection effect of ozone water disinfector in the comprehensive oral treatment system. Methods using ozone water disinfector to produce about 2 mg / L ozone water to wash and disinfect the water system of 14 comprehensive oral treatment stations, the water samples of mobile phone outlet were collected before disinfection and 10 minutes after disinfection with 1 mg / L ozone water disinfector, respectively. After 48 hours culture at 37 鈩,
