（1）纤维支气管镜的洗涤。在进行之前，纤维支气管镜应进行仔细的清理，用溶液对纤维支气管镜及活检钳、吸引及咬口进行洗涤后用75%的酒精进行擦拭。用2%的碱性戊二醛溶液对纤维支气管镜及活检钳、吸引及咬口进行浸泡。
(1) Washing of fiberoptic bronchoscope. Before disinfection and sterilization, the fiberoptic bronchoscope should be carefully cleaned. After washing the fiberoptic bronchoscope, biopsy forceps, suction and bite with solution, wipe it with 75% alcohol. Fiberoptic bronchoscope, biopsy forceps, suction and bite were soaked with 2% alkaline glutaraldehyde solution.
（2）插入部的清洁。使用后立即用湿纱布擦拭插入部，除去插入部浸入洗涤液（洗必泰溶液 ）中，用纱布或者海绵轻轻擦拭，然后用水进行漂洗。
(2) Cleaning of insertion part. Wipe the insertion part with wet gauze immediately after use, remove the insertion part, immerse it in the washing solution (chlorhexidine solution), wipe it gently with gauze or sponge, and then rinse with water.
（3）吸引阀的清洁。取出吸引阀杆，浸入洗涤液中，擦洗吸引阀杆外表面和内孔。旋松螺帽，取出吸引阀体，浸入洗涤液中，用纱布或者海绵轻轻擦洗吸引阀体外表面和内孔。用清洁刷蘸上清洗液，从插钳口插入，在钳道内反复多次清洗。
(3) Cleaning of suction valve. Take out the suction valve rod, immerse it in the washing solution, and scrub the outer surface and inner hole of the suction valve rod. Unscrew the nut, take out the suction valve body, immerse it in the washing solution, and gently scrub the outer surface and inner hole of the suction valve with gauze or sponge. Dip the cleaning brush with cleaning liquid, insert it from the jaw, and clean it repeatedly in the jaw.
（4）清洁活检(吸引)管道。用清洁刷蘸上清洗液，从插钳口插入，在钳道管内反复多次清洗。清洗刷不可中途反向运动，要等到刷头从头端部完全露出后，才可以反向运动，以免损坏钳道管内壁。
(4) Clean the biopsy (suction) tube. Dip the cleaning brush into the cleaning solution, insert it from the jaw, and clean it repeatedly in the Tong pipe. The cleaning brush shall not move in reverse halfway. It can not move in reverse until the brush head is completely exposed from the head end, so as not to damage the inner wall of Tong pipe.

（5）清洗洗涤插钳口密封阀及插钳口。钳子和吸引管道清洗时可用清洗刷分别从纤维支气管镜的钳子插入口和吸引道口插入，清洗刷多次反复来回清洗效果更好。
(5) Clean the sealing valve of the washing socket and the socket. When cleaning the forceps and suction pipes, the cleaning brush can be inserted from the forceps insertion port and suction passage port of the fiberoptic bronchoscope respectively. The cleaning brush can clean back and forth repeatedly for many times, and the effect is better.
（6）测漏试验。每次进行浸泡前要进行测漏试验，将通气阀从导光插头部上取下，然后将漏水检测器的连接头装在导光插头部的通气阀上。将镜子浸入水中，加压到一定压力，仔细观察大约30s，如无气泡从镜子中漏出，可以进行全防水浸洗和，浸泡时间≤1 h。如发现有连续的气泡冒出，说明此纤维支气管镜漏水，应立即将镜子从水中取出擦干，以防止水进入镜子的内部而造成脱胶、图像模糊等。将整个支气管镜从水中取出时，松开压力表的放气旋钮，使镜子内压与外环境压力平衡。等待30s直到包裹弯曲部的橡皮套恢复正常。按逆时针方向按压，旋拧漏水检测器的连接头，将其从镜子的导光插头部的通气阀上取下。
(6) Leak test. Before each immersion disinfection, a leakage test shall be carried out, the vent valve shall be removed from the light guide plug, and then the connector of the water leakage detector shall be installed on the vent valve at the light guide plug head. Immerse the mirror in water, pressurize it to a certain pressure, and observe carefully for about 30s. If there is no bubble leaking from the mirror, it can be fully waterproof, soaked and disinfected, and the soaking time is ≤ 1H. If continuous bubbles are found, it indicates that the fiberoptic bronchoscope is leaking. Take the mirror out of the water and wipe it dry immediately to prevent water from entering the interior of the mirror and causing degumming, image blur, etc. When taking out the whole bronchoscope from the water, loosen the deflation knob of the pressure gauge to balance the internal pressure of the mirror with the external ambient pressure. Wait for 30s until the rubber sleeve wrapping the bending part returns to normal. Press counterclockwise, screw the connector of the water leakage detector and remove it from the vent valve at the light guide plug of the mirror.
