説明

<p>Medical technologies related to laparoscopic surgery and orthopedic surgery have made remarkable progress. With these advances, surgical instruments have become more and more complex. The complex structures have many gaps, and if contaminants such as blood or body fluids adhere to them, they are difficult to clean.</p><p>In terms of water temperature in pre-cleaning process of washer disinfector, there is a report that protein denaturation may occur when the temperature of the process is higher than 50°C. It is essential to investigate the relationship between water temperature and cleaning effectiveness in the pre-cleaning process in order to achieve efficient and reliable cleaning performance of medical instruments. In this study, we investigated the effect of water temperature in pre-cleaning process on removal of blood.</p><p>Compared to pre-cleaning process with non-heated or 40°C water, the process with water at 50°C resulted in a higher amount of residual protein after the main cleaning. In cleaning with Washer-Disinfector, the water temperature of the pre-cleaning process is an important factor to obtain high cleaning performance. Based on the results of this study, it is desirable to perform the pre-cleaning process with water at 40°C or lower.</p>
