There are many types of endoscopes, such as gastroscopes and colonoscopes for the digestive system, tracheoscopes and bronchoscopes for the respiratory system, and others such as laryngoscopes, encephaloscopes, arthroscopes, cystoscopes, laparoscopy, etc. Endoscopes are mainly used for clinical medical examinations, diagnosis, and treatment. They must be inserted into the patient's body when used. Therefore, the endoscope must be thoroughly cleaned, disinfected, and sterilized after each use to prevent cross infection caused by bacterial contamination.

[0003] Compared with traditional cleaning methods, the advantages of spray cleaning are mainly reflected in the following aspects: 1) Higher cleaning efficiency: Spray cleaning machine adopts the principle of mechanical spraying, which can evenly and efficiently spray cleaning liquid on the surface of the object to be cleaned, ensuring that every part can be fully cleaned. This efficient cleaning method can significantly shorten the cleaning time and improve production efficiency. 2) Better cleaning quality: Spray cleaning can generate strong impact through the spray system to effectively remove dirt and impurities.
