AI Technical Summary

Technical Problem

Traditional cardiothoracic surgery drainage tube status recognition systems rely on image matching, which makes it difficult to accurately capture dynamic changes in the fluid, resulting in a high misjudgment rate and a lack of continuity and overall trend recognition, thus affecting the timeliness of postoperative intervention.

Method used

The system constructs a continuous state recognition system by extracting the visual location of the drainage fluid through the drainage imaging positioning module, analyzing the displacement of the liquid front boundary through the leading edge rhythm discrimination module, calculating the change in liquid column length through the liquid column direction discrimination module, screening the synchronization interval through the state collaborative recognition module, and matching the image timestamps through the running state labeling module.

Benefits of technology

It enhances the ability to quantitatively track the dynamic characteristics of liquids, improves the accuracy and stability of state recognition, reduces single-frame visual misjudgment, and realizes time-series drainage state monitoring.

Abstract

The invention relates to the technical field of medical state monitoring, in particular to a cardiothoracic surgery drainage tube running state mode recognition system which comprises a drainage imaging positioning module, a leading edge rhythm judgment module, a liquid column direction judgment module, a state collaborative recognition module and a running state labeling module. According to the method, the visual range of the drainage liquid in the transparent section is positioned through the continuous images, the leading edge boundary and the starting and ending positions of the liquid column are extracted, the quantitative tracking capability of the dynamic characteristics of the liquid is enhanced, and the recognition accuracy of stagnation and flowing states is improved through leading edge displacement change and rhythmicity analysis; the judgment of the length change direction of the liquid column defines the flow direction of the liquid, reduces single-frame visual misjudgment, cooperatively judges the leading edge state and the direction of the liquid column, screens out a synchronous section, improves the stability and consistency of state recognition, completes state labeling in combination with an image timestamp, constructs a sequential and continuous operation state recognition system, and improves the accuracy of state recognition. And the intelligence and accuracy of drainage state monitoring are enhanced.
