Abstract：Tracheoscopy, as a common examination of the interior of the trachea, is wildly used in diagnosis of coughing of unknown causes, suspicion of tumor and other diseases. It is required to clean and disinfect sophisticated surgical instruments before and after examination. The conventional manual cleaning method not only leads to huge cost of manpower and material resources, but also damages the sophisticated surgical instruments. This paper introduced a self-made mechanical vibration washing device for nurses in the bronchoscopy room. This device works by circulative impinging of water fluid, so as to save the water resource. It can also reduce the workload of nurses and damage on sophisticated surgical instruments.
