In hospitals, medical instruments are usually cleaned and disinfected in a washer/disinfector. However, it is not efficient for small hospitals or general practitioners to purchase such machines as they would not be working to capacity. We investigated the possibility of cleaning and disinfecting medical equipment in a conventional household dishwasher modified to achieve a temperature of 71 degrees C. For this purpose we contaminated screws with different test soils containing either bacterial (100 screws) or viral (106 screws) suspensions. Test organisms were re-isolated from 2% of the screws after bacterial contamination and 4.7% of those with viral contamination. In both cases we found dishwasher-processing to be a suitable means of disinfecting medical instruments.
在医院里，医疗器械通常在清洗消毒机中进行清洁和消毒。然而，对于小型医院或全科医生来说，购买这样的机器效率不高，因为它们无法满负荷运转。我们研究了在一台经过改装以达到71摄氏度温度的传统家用洗碗机中对医疗设备进行清洁和消毒的可能性。为此，我们用含有细菌（100颗螺丝）或病毒（106颗螺丝）悬浮液的不同测试污垢污染螺丝。细菌污染后，从2%的螺丝中重新分离出测试微生物；病毒污染后，从4.7%的螺丝中重新分离出测试微生物。在这两种情况下，我们都发现用洗碗机处理是消毒医疗器械的一种合适方法。
