A medical drainage tube anti-blockage and unblocking device
By designing a medical drainage tube anti-blockage and unblocking device that adapts to different pipe specifications, the problem of poor compatibility of drainage tube blockage has been solved. This has enabled the adjustment of negative pressure suction force and the device's compatibility with various pipes, thereby improving the stability and safety of suction.

Abstract
This invention provides a medical drainage tube anti-blockage and unblocking device, belonging to the field of medical device technology. It includes a suction device with a power cord, a display screen, and an adjustment knob for adjusting suction force. A connecting tube is also fixedly installed on the suction device, and a collection component is connected to the connecting tube via a locking assembly. In this solution, a three-way connector connects the patient's tubing, collection tube, connecting tube, and backflushing assembly. Negative pressure draws tissue samples and body fluids from the patient through the connecting column and three-way connector into the collection tube, ultimately storing them in a collection bag, completing tissue extraction and collection. The negative pressure is adjustable throughout the process to adapt to different tissue extraction needs. The tapered connector significantly improves the device's clinical versatility and reduces the frequency of consumable replacement.
