[A new system for noninvasive esophageal varices pressure measurement based on airflow and laser technology]
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.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
