[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art based on the present application are within the scope of protection of the present application.
[0029] Before introducing the embodiments of the present application, first, the application scenario and the execution subject of the present application will be described. Figure 1 The application scenario and the execution subject of the present application will be described.
[0030] Figure 1 The system includes a signal generation device 11, an IABP host 12 and an IABP 13. The signal generation device 11 is connected with the IABP host 12, the signal generation device inputs a test signal to the IABP host 12, and the IABP host 12 controls the operation of the IABP 13 by using the test signal to perform performance testing.
[0031] The signal generation device is used to generate a test signal for performance testing of the IABP host, and the signal type of the test signal is the same as the signal type of the trigger signal for controlling the operation of the IABP host. For example, the signal type of the trigger signal includes an electrocardiogram signal type and an arterial pressure signal type, and correspondingly, the signal type of the test signal generated by the signal generation device also includes the electrocardiogram signal type and the arterial pressure signal type.
[0032] The special test signal generated by the signal generation device can effectively simulate the actual operation environment of the IABP, thereby realizing the authenticity and accuracy of the IABP host testing.
[0033] The scheme provided for the embodiments of the present application will be described below.
[0034] Referring to Figure 2 , Figure 2 A structural schematic diagram of a first signal generation device for IABP host testing provided for an embodiment of the present application.

[0035] The power module 201 supplies power to the signal generation motherboard; the data storage module 203 and the digital-to-analog converter module 204 are connected to the control module 202, and the digital-to-analog converter module 204 is connected to the analog signal output module 205.
[0036] The control module 202 sends control commands to the data storage module 203 and the digital-to-analog conversion module 204 to obtain the digital signal parameters of the preset physiological data stored in the data storage module 203, and controls the digital-to-analog conversion module 204 to convert the digital signal parameters into an analog signal type test signal. The digital-to-analog conversion module 204 controls the analog signal output module 205 to output the test signal to the IABP host so that the IABP host can perform performance testing.
[0037] The aforementioned digital signal parameters are preset signal parameters for the trigger signals used by the IABP host to control operation.

Since the above digital signal parameters are the signal parameters corresponding to the trigger signals for the IABP host to control the operation, the test signals converted from the above digital signal parameters can be used as the trigger signals for the IABP host, thereby realizing the simulation of the actual operating environment of the IABP host.

These test signals can be used as trigger signals required for IABP host performance testing, thereby realizing test signals for IABP host performance testing. Compared with collecting actual signals as test signals, a large number of test signals for IABP host testing can be generated in a short time, and the testing cost is significantly reduced.

[0045] The power module 301, the control module 302, the data storage module 303, and the digital-to-analog conversion module 304 are the same as the foregoing Figure 2 The same as the foregoing corresponding embodiment, which will not be described here.
