The analog signal generating module 30 includes a power detecting circuit 31 and an analog signal generating circuit 32.
The power detection circuit 31 is connected with the power connection terminals (21 and 22), and the power detection circuit 31 obtains power supply through the power connection terminals (21 and 22) and the interface of the lead wire 300 connected to the invasive blood pressure monitor 200. Typically, 5V dc power is available from the interface of invasive blood pressure monitor 200.
The analog signal generating circuit 32 is connected to the signal connecting terminals (23 and 24), and the analog signal generating circuit 32 generates a monitor detection signal, which is output to the invasive blood pressure monitor 200 through the signal connecting terminals (23 and 24) and the lead wire 300, so as to detect the invasive blood pressure monitor 200.

The first indicator light 311(LED1) is a green indicator light, the positive electrode of the first indicator light LED1 is connected to the positive electrode connecting terminal 21(+ EXCITER) through a resistor R13 and a function switch K2, and the negative electrode thereof is connected to the negative electrode connecting terminal 22 (-EXCITER).
The second indicator light 312(LED2) is a red indicator light, the anode of the second indicator light LED2 is connected to the negative terminal 22 (-excenter) through a resistor R14, and the cathode thereof is connected to the positive terminal 21(+ excenter) through a function switch K2.
When the second stationary contact of the function changeover switch K2 is connected to the second movable contact, i.e., the first indicator light LED1 and the second indicator light LED2 are connected between the positive terminal 21(+ excenter) and the negative terminal 22 (-excenter). When a user tries to connect four or five wires of the lead wires with a plurality of connecting terminals to detect a power line, if the positive connecting terminal 21(+ excenter) and the negative connecting terminal 22 (-excenter) are correctly connected with a power interface of an interface of the invasive blood pressure monitor, the first indicator light LED1 is turned on, namely the green indicator light is turned on, and the second indicator light LED2 is not turned on, namely the red indicator light is turned off. If the positive terminal 21(+ excenter) and the negative terminal 22 (-excenter) are connected with the power interface of the invasive blood pressure monitor interface, and the positive terminal and the negative terminal are reversely connected, the first indicator light LED1 is not turned on, namely the green indicator light is turned off, and the second indicator light LED2 is turned on, namely the red indicator light is turned on. If the signal or the shielding wire of the lead wire 300 is connected to the power connection terminal, the two indicator lights are not lighted, so that the power line can be checked through a limited number of attempted connections, and the power line of the lead wire 300 is correctly connected with the power connection terminal, so that the invasive blood pressure monitor detecting device 100 can obtain power from the invasive blood pressure monitor 200.

When the signal line of the lead line 300 is correctly connected to the first signal connection terminal 23(+ OUTPUT) and the second signal connection terminal 24(-OUTPUT), the invasive blood pressure monitor detecting device can generate a monitor detecting signal and OUTPUT the monitor detecting signal to the invasive blood pressure monitor 200, so as to correct the invasive blood pressure monitor 200. The invasive blood pressure monitor 200 can display corresponding data on the display screen, and if the display data is positive, it indicates that the signal lines are correctly connected, and if the display data is negative, it indicates that the signal lines are corresponding, but the direction connection is wrong, so two signal lines of the lead line need to be connected with the first signal connection terminal 23(+ OUTPUT) and the second signal connection terminal 24(-OUTPUT) after the positions of the two signal lines are adjusted. If the shielded line of the lead line is connected to the first signal connection terminal 23(+ OUTPUT) and the second signal connection terminal 24(-OUTPUT), the connection is incorrect, and the corresponding signal line and shielded line are found by pairing each two, and the connection is fast.

After the invasive blood pressure monitor receives the electrical signal, the display screen of the invasive blood pressure monitor 200 should display the word "please zero" to remind the user to zero the invasive blood pressure monitor 200. When the second gear switching contact of the gear switch K1 is connected to the first stationary contact, the first gear matching resistor R12 is connected to the analog signal generating circuit 32, and at this time, the first signal connection terminal and the second signal connection terminal of the invasive blood pressure monitor detection device output an electrical signal corresponding to the second gear to the invasive blood pressure monitor.

After the invasive blood pressure monitor receives the electrical signal, the display screen of the invasive blood pressure monitor 200 should display the voltage data corresponding to the shift of the shift switch K1, so that the user can conveniently determine whether the voltage data of the invasive blood pressure monitor at this time is correct.
In this embodiment, the shift switch K1 is a knob switch, and in other embodiments, the shift switch may also be a key switch or a touch screen setting control.
