Abstract

The invention discloses a probe package structure of a human body pressure measuring sensor. The probe package structure comprises a wire, a protection tube, a micro PCB (printed circuit board), a pressure chip and a transition wire, wherein the wire is powered on by the pressure chip and is used for signal transmission; the protection tube is provided with a groove, one end of the protection tube is in sealing communication with a plastic conduit, and the other end is a closed end; the micro PCB is placed in the groove, and a signal output end of the micro PCB is connected with the wire; the pressure chip is placed in the groove, and a sensing surface of the pressure chip is perpendicular to the opening direction of the groove; the transition wire is connected with the pressure chip and the micro PCB; a gap between the pressure chip and the protection tube is filled with protective glue; the surface of the pressure chip is filled with the protective glue; and a low stress medium is filled between the pressure chip and the micro PCB. The chip in the invention is minimally subjected to external stress, thereby ensuring minimum fluctuation of the output value of a packaged sensor and minimum time drift, avoiding the risk of short circuit, improving the stability of test value of the pressure chip, and thus effectively improving the accuracy of pressure monitoring.
