我国是乙型肝炎(乙肝)高发区,乙肝表面抗原(HBsAg)携带者达10％～15％。有人对300例拔牙器械盘采样,测定HBsAg,结果器械中的阳性率为4.7％,污物为6.1％。由于病人的血液、唾液、尿液等分泌物都可以污染医疗器械,因而器械的消毒十分复杂又具有重要临床意义。为了寻找理想的化学消毒剂,即高效广谱、速效无毒、性质稳定、价廉、安全等五大特点的药物,不少学者进行了大量研究,现
China is a high incidence of hepatitis B (hepatitis B), hepatitis B surface antigen (HBsAg) carriers of up to 10% to 15%. Some 300 cases of tooth extraction instrument tray sampling, determination of HBsAg, the results of the device in the positive rate of 4.7%, dirt was 6.1%. As the patient’s blood, saliva, urine and other secretions can contaminate medical equipment, so the disinfection of equipment is very complex and has important clinical significance. In order to find the ideal chemical disinfectants, that is, efficient and broad-spectrum, quick non-toxic, stable, cheap, safe and other five major characteristics of the drug, many scholars conducted a lot of research, and now
