Jugular Vein Motion Sensing for Early Heart Hypofunction Detection

The patent uses the jugular vein as an intermediary structure to indirectly measure right atrial pressure. Instead of directly inserting sensors into the heart, the system places a sensor on the external jugular vein, which transmits pressure variations from the right atrium to the external surface. This mediator approach allows accurate measurement while avoiding invasive surgical procedures and their associated risks.

The patent replaces complex mechanical ultrasound equipment with a simple motion sensor (such as an accelerometer or gyroscope) that detects movements of the jugular vein. This substitution transforms a sophisticated medical imaging system into a simple motion detection device, dramatically reducing cost and complexity while maintaining the ability to detect heart hypofunction through characteristic movement patterns of the jugular vein.

The patent enables the system to automatically detect and analyze jugular vein movement patterns without requiring skilled ultrasound operators. The motion sensor continuously records vein movements, and the system automatically processes the data to detect signs of heart hypofunction. This self-service approach eliminates the need for specialized medical training while maintaining diagnostic accuracy.
