The electrical connector 300 is fixedly penetrated on the insulating container 100 and electrically connected to the detection liquid in the liquid storage cavity 101. The external power supply equipment (not shown in the figure) can transmit high-voltage energy to the detection liquid in the liquid storage cavity 101 through the electrical connector 300, and then transmit it to the invasive blood pressure monitoring device to be detected via the liquid path of the hydraulic outlet 111.
