TRANSDUCER FOR MEASURING PULSE BEATING BLOOD PRESSURE WAVE INTENSITY AND VESSEL WIDTH

摘要

The present invention is disclosed a sensor for the kind of pulsating pressure wave intensity and vascular width measurement , which includes a housing, a sensor probe, the circuit board, the lead line, and wherein the sensor probe is double beam elastic body structure, the double-beam structure is symmetrical. Preferably, the sensor probe has a double multi probe beam elastic body structure, and provided with a double beam corresponding to each probe, over two beams corresponding to each of the probes, and dual-resistance silicon strain gauges are provided symmetrically, wherein each pair of double-resistance silicon strain gauges corresponding to the probe form one Wheatstone bridge, and through the bridge to detect the change in the voltage of each probe is measured and measurement of vascular pressure. Sensor of the present invention can afford the overhead high sensitivity and accuracy, a multi-probe wave intensity with a pulsating pressure and vascular width measurement sensor having a self-protection. ;
