AI Technical Summary

Technical Problem

Existing closed thoracic drainage devices require manual intervention when the collection bottle is full, which is cumbersome and slow. They cannot record abnormal pressure fluctuations in real time, are difficult to observe at night or from a distance, and lack historical data support.

Method used

Automatic drainage and pipeline clamping are achieved by linking a drainage mechanism with a mechanical valve. A float and pointer are linked to display respiratory fluctuations, and large swings of the pointer are recorded to record abnormal events.

Benefits of technology

It achieves automated diversion, significantly improving diversion safety and ease of observation, providing historical data support, and reducing the difficulty of observation and the risk of retrograde infection.
