説明

The mycobacterial contamination of a bronchoscope has been a problem. At our institution, there was several cases of such contamination. Atypical mycobacterial contamination of tap water could not prevent by installation of 0.2μm filter system in the case of intermittent use of water. The highest contamination was found in the connection tube between filter systems. During the course of our trial to prevent atypical mycobacterial contamination, we recognized the importance of brushing. Using artificial sputum, we studied a simplified cleaning method for the bronchoscope. For the first step of cleaning a bronchoscope, we must physically wash it. For washing it, it is necessary to brush every part of the device 10 or more times. We test-produced a simplified cleaning device which uses 1.0kg/cm2 water pressure and benzalkonium chloride. It can be semi-automatically washed and it is useful because it is labor-saving. Because of its structure, suction valves were easily contaminated. Therefore, it needs to be carefully brushed, cleaned, and sterilized. The endoscope automatic washer (Olympus EW-10) is not perfect. The concentration of glutaraldehyde in EW-10 system decreased from 2 to 1.1% during one week. It is necessary to take care in having the user clean it by himself.
