The DEKO-190 Washer-Disinfector combines both automatic washing and thermal disinfection functions and is designed for the decontamination of ward utensils (such as bedpans and urine bottles) and instruments used in minor surgery prior to sterilization. We undertook a microbiological evaluation of the disinfection efficacy of the machine, using its short wash plus disinfection programme and sealed suspensions of test organisms placed at various points within the instrument. Suspensions of Enterococcus faecalis and Poliovirus were totally inactivated, the counts of aerobic organisms within a stool specimen being reduced by a factor of 10(4)whilst spores of Clostridium perfringens were unaffected. The cleaning efficacy of the DEKO-190 was also evaluated under clinical conditions by visual inspection and was found to be satisfactory. Ward-based combined washer-disinfection machines, such as the DEKO-190, have the potential to improve the efficacy of cleaning protocols within healthcare institutions.
DEKO - 190清洗消毒机兼具自动清洗和热力消毒功能，专为病房用具（如便盆和尿瓶）以及小型手术所用器械在灭菌前的去污处理而设计。我们使用该机器的短洗加消毒程序，并将测试微生物的密封悬浮液置于器械内的不同位置，对其消毒效果进行了微生物学评估。粪肠球菌和脊髓灰质炎病毒的悬浮液被完全灭活，粪便标本中的需氧菌数量减少了10⁴倍，而产气荚膜梭菌的孢子则未受影响。通过目视检查在临床条件下对DEKO - 190的清洁效果进行了评估，结果令人满意。基于病房的组合式清洗消毒机，如DEKO - 190，有潜力提高医疗机构内清洁规程的效果。
