Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to an endoscope cleaning brush that can prevent the brush head from falling off. Background Technology

[0002] The main functions of an endoscope cleaning brush include: 1) Cleaning the endoscope surface: Endoscopes are contaminated with various pollutants during use, such as blood, mucus, and bacteria. Using an endoscope cleaning brush effectively removes these contaminants and bacteria, ensuring the cleanliness and hygiene of the endoscope. 2) Preventing cross-infection: There is a risk of cross-infection when endoscopes are used between different patients. Since endoscope cleaning brushes are usually disposable, they can be discarded after use without the need for further cleaning and disinfection, thus avoiding the risk of cross-infection. 3) Extending the lifespan of the endoscope: Regular cleaning with an endoscope cleaning brush can extend the lifespan of the endoscope, reduce the frequency of repairs and replacements, and save medical resources. 4) Convenience and speed: The endoscope cleaning brush has a simple design and is easy to operate. After using the endoscope, medical staff can quickly and easily complete the cleaning work by simply using the cleaning brush.

[0003] Existing endoscope cleaning brushes have significant design flaws. These products typically employ an integrated brush head and main shaft design, meaning the entire brush can only be used once. In practice, whether a single cleaning task is completed or the brush head is damaged, the entire brush, including the main shaft, must be discarded, wasting this still-usable component. Therefore, existing endoscope cleaning brushes need to be optimized and improved. Summary of the Invention
