The analog signal generation module 30 includes a power supply detection circuit 31 and an analog signal generation circuit 32.
The power supply detection circuit 31 is connected with the power supply wiring terminals (21 and 22), and the power supply detection circuit 31 obtains a power supply through the power supply wiring terminals (21 and 22) and the interface of the lead wire 300 connected to the invasive blood pressure monitor 200.

When the second stationary contact of the function switching switch K2 is connected to the second movable contact, that is, the first indicator lamp LED1 and the second indicator lamp LED2 are connected between the positive terminal 21 (+ EXCITER) and the negative terminal 22 (-EXCITER). When the user tries to connect with several connection terminals by four or five wires of the lead wire to detect the power wire, if the positive connection terminal 21 (+ EXCITER) and the negative connection terminal 22 (-EXCITER) are connected correctly with the power interface of the invasive blood pressure monitor, the first indicator light LED1 is turned on, i.e. the green indicator light is turned on, and the second indicator light LED2 is not turned on, i.e. the red indicator light is turned off. If the positive electrode connecting terminal 21 (+ EXCITER) and the negative electrode connecting terminal 22 (-EXCITER) are connected with the power interface of the invasive blood pressure monitor, and the positive electrode and the negative electrode are reversely connected, the first indicator light LED1 is not on, namely the green indicator light is turned off, and the second indicator light LED2 is on, namely the red indicator light is turned on. If the signal or shielding wire of the lead wire 300 is connected to the power connection terminal, the two indicator lamps are not turned on, so that the power wire can be checked through limited attempts to connect, and the power wire of the lead wire 300 is correctly connected with the power connection terminal, so that the invasive blood pressure monitor detecting apparatus 100 can obtain power from the invasive blood pressure monitor 200.

When the signal line of the lead wire 300 is correctly connected with the first signal connection terminal 23 (+output) and the second signal connection terminal 24 (-OUTPUT), the invasive blood pressure monitor detecting apparatus may generate a monitor detection signal and OUTPUT the monitor detection signal to the invasive blood pressure monitor 200, so as to correct the invasive blood pressure monitor 200. The display screen of the invasive blood pressure monitor 200 displays corresponding data, and if the display data is positive, the signal lines are correctly connected, and if the display data is negative, the signal lines are corresponding to each other, but the direction connection is wrong, so that it is necessary to adjust the positions of the two signal lines of the lead line and then connect the two signal lines to the first signal connection terminal 23 (+output) and the second signal connection terminal 24 (-OUTPUT). If the shielded wires of the lead wires are connected to the first signal connection terminal 23 (+output) and the second signal connection terminal 24 (-OUTPUT), and are connected in error, the corresponding signal wires and shielded wires are found out through pairwise pairing, and quick connection is achieved.

After the invasive blood pressure monitor receives the electrical signal, the display screen of the invasive blood pressure monitor 200 should display voltage data corresponding to the gear of the gear switch K1, so that a user can determine whether the voltage data of the invasive blood pressure monitor at this time is correct.
In this embodiment, the gear switch K1 is a knob switch, and in other embodiments, the gear switch may also be a key switch, or a touch screen setting control.
In an alternative embodiment, to implement switching between the power line detection and the signal line detection, the analog signal generating module further includes a function switch 33 (i.e., a single pole double throw switch K2), where the function switch K2 is a single pole double throw switch K2, and includes a second stationary contact, a first movable contact, and a second movable contact; the second stationary contact is connected to the positive terminal 21 (+ EXCITER) of the power supply terminal, the first movable contact is connected to the third resistor R3 and the fourth resistor R6 of the analog signal generating circuit 32, and the second movable contact is connected to the first indicator LED1 and the second indicator LED2 of the power supply detecting circuit 31.
