Abstract
Objective This study aimed to investigate the required air-injection duration for drying bronchoscope channels of different specifications.Methods Two types of bronchoscopes were manually cleaned and disinfected after clinical use.A pressure air gun at 0.4 MPa was used to inject air into the biopsy channel and the suction channel separately.After air injection,cobalt chloride test paper was fully contacted with the inner lumen,and drying was determined based on the color change of the paper.In the first group,air was injected into both channels for 10 seconds,with 30 repeated tests.The injection time was then increased by 10 seconds per group until all 30 tests indicated dry channels.Results For a bronchoscope with a biopsy channel diameter of 2.0 mm,air injection for 30 seconds into each channel achieved drying.For a bronchoscope with a biopsy channel diameter of 3.0 mm,air injection for 40 seconds was required.Conclusion Different air-injection times are recommended for bronchoscopes of different specifications:30 seconds for those with a 2.0 mm biopsy channel and 40 seconds for those with a 3.0 mm biopsy channel.关键词
