An adaptive suction system for lumen state recognition
By using an adaptive aspiration system to identify the lumen status and controlling it with pressure sensors and solenoid valves, the problem of the inability to identify the lumen status in existing technologies has been solved, achieving the effects of reducing blood loss and quickly removing thrombi, thus improving surgical efficiency.

AI Technical Summary
Technical Problem
Existing aspiration techniques cannot effectively identify the condition of the lumen, making it difficult for doctors to determine whether the blood vessel is open or whether the tube is blocked, which prolongs the operation time and may cause blood loss.
Method used
An adaptive aspiration system is used, which identifies the lumen status through pressure sensors and sensor networks, and combines this with solenoid valves to control the opening and closing of the tubing, thereby achieving adaptive aspiration, reducing blood loss and quickly removing thrombi.
Benefits of technology
It effectively identifies the condition of the lumen, reduces blood loss, shortens operation time, improves surgical efficiency, and reduces radiation exposure.

Abstract
This invention discloses an adaptive aspiration system for identifying the state of a blood vessel, comprising: a negative pressure aspiration main unit with a vacuum pump inside; a waste liquid collection device disposed at the aspiration end of the negative pressure aspiration main unit; and an intermediate aspiration device connected to the negative pressure aspiration main unit. The discharge end of the intermediate aspiration device is connected to the waste liquid collection device, and the inlet end of the intermediate aspiration device is connected to the aspiration conduit. The system utilizes the negative pressure generated by the negative pressure aspiration main unit to aspirate and remove thrombi from the blood vessels. The adaptive aspiration of this invention is based on pressure sensor measurements of the tubing, and the system program determines whether the lumen is filled with pure blood, blood mixed with a large amount of thrombus, or the tubing is blocked, and then performs appropriate aspiration accordingly.
