Abstract： |
A non-invasive method and system for measuring the intenral pressure of abdominal cavity is disclosed. A pressure-shift sensor is composed of pressure sensor and shift sensor. Its method includes such steps as changing the extenal pressure, measuring the variation of output voltage of pressure sensor by data measuring and processing system, mathematically fitting acquired data to obtain an internal pressure-external pressure converting equation, and calculating the internal pressure. |
