Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a flexible endoscope bedside pretreatment device. Background Art

[0002] According to the Technical Specification for Cleaning and Disinfection of Flexible Endoscopes WS507-2016, after the flexible endoscope is used for examination, diagnosis or treatment, the flexible endoscope is taken out of the patient's body. Before being detached from the host, the insertion part is first placed in the enzyme liquid barrel, the negative pressure suction button is pressed to allow the enzyme liquid to fully flush the lumen, the air and water supply buttons are pressed, and bubbles are observed in the enzyme liquid barrel. Then, wet wipes or wet gauze containing enzyme liquid are used to wipe the insertion part. The existing bedside pretreatment process uses enzyme liquid inefficiently and wastefully, and the pretreatment effect of flexible endoscopes is not ideal. Usually, there are the following methods:

[0003] Existing usage plan 1: enzyme liquid barrel
