Description

Technical Field

[0002] With the development of medical conditions, it is becoming more and more common to use endoscopy to assist in the medical judgment of difficult and complicated diseases. As an instrument that invades the human cavity or directly contacts the human body, the flexible endoscope is difficult to achieve complete sterilization requirements due to its complex structure and special materials. Once the human body's defense barrier is destroyed during operation, the chance of medical infection will be greatly increased. Therefore, a lot of work needs to be done before and after the use of the endoscope, such as leak detection, pre-cleaning water washing, multi-enzyme washing, re-water washing, sterilization disinfectant immersion, re-water washing, alcohol washing, air drying, etc.

[0003] The main function of multi-enzyme flushing is to remove tissue attachments on the surface of the endoscope, such as mucus, blood, protein, etc., so the cleaning effect is also crucial. Multi-enzyme cleaning agents are general cleaning consumables in the infection control management of medical institutions, and multi-enzyme cleaning agents are disposable products and cannot be reused. Although multi-enzyme cleaning agents on the market claim to have multiple functions, such as lubrication and rust removal, in actual applications, they often fail to fully demonstrate the expected effects due to improper ingredient ratios and insufficient activity.
