OBJECTIVE: Combined the optical principle with automatic control technology and computer real-time image detection technology to develop a non-contact system for noninvasive esophageal varices pressure measurement.
METHODS: The system included the adjustable air pump, laser device, image collection and analysis program. The feasibility and accuracy of the system were verified by in vitro experiments.
RESULTS: The bionic vascular pressure measured by this system had good correlation and repeatability with the actual pressure.
CONCLUSIONS: This system is accurate, feasible and has good application prospects.
