Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a visual drainage tube. Background Technology
[0002] A drainage tube is a common medical device. It is used to drain fluid from body cavities, removing excess fluid and maintaining pressure balance within the body. In clinical medicine, drainage is required in areas such as the pleural cavity, cranial cavity, lumbar cistern, and bladder.

When inserting drainage tubes, the "blind puncture" method is generally used, which means that the doctor's experience determines the puncture location and depth. As a result, inaccurate puncture of the drainage tube is inevitable, leading to puncture failure and repeated punctures, or incorrect placement of the tube, resulting in poor drainage effect. Utility Model Content
