[0137] In this embodiment, the real-time data of the pressure value in the pressure change data to be tested is compared with the target pressure range to obtain a comparison result. At the same time, the vibration amplitude in the vibration optical fiber data to be tested is compared with the target vibration amplitude range to obtain a comparison result. The two comparison results are combined to determine whether the flow rate increase in the drainage tube flow rate data to be tested within the first preset time exceeds the flow rate threshold. The specific state of the surgical site is predicted based on the judgment result of whether the photoelectric sensor data to be tested within the first preset time is greater than the threshold.

[0138] In one embodiment of the present application, the state of the sample to be tested is determined based on the obtained pressure change data to be tested, the drainage tube flow rate data to be tested, the vibration optical fiber data to be tested, and the target pressure range, target flow rate range, and target vibration amplitude range corresponding to the surgical site in the obtained sample to be tested data, and further includes the following S504h to S504k:

[0139] S504h, when the pressure value in the pressure change data to be tested is within the target pressure range, and when the vibration amplitude in the vibration optical fiber data to be tested is within the target vibration amplitude range, the drainage tube flow velocity data to be tested and the photoelectric sensor data to be tested are obtained once every third preset time, and the drainage tube flow velocity data to be tested and the photoelectric sensor data to be tested obtained twice adjacent to each other after the third preset time are further judged.

[0140] S504i, when the flow rate increase in two adjacent drainage tube flow rate data to be tested obtained after the third preset time is within the first preset flow rate range, and when the color difference in two adjacent photoelectric sensor data to be tested obtained after the third preset time is within the first preset color difference range, it is judged that the surgical site is normal.

[0141] S504j, when the flow rate increase in two adjacent drainage tube flow rate data to be tested obtained after the third preset time is within the first preset flow rate range, and when the color difference in two adjacent photoelectric sensor data to be tested obtained after the third preset time is not within the first preset color difference range, it is judged that inflammation occurs at the surgical site and a warning message is sent.

[0142] S504k, when the flow rate increase in two consecutive drainage tube flow rate data to be tested obtained after the third preset time is not within the first preset flow rate range, and when the color difference in two consecutive photoelectric sensor data to be tested obtained after the third preset time is not within the first preset color difference range, it is judged that the drainage of the surgical site is not smooth, and a warning message is sent.

[0143] Specifically, the third preset time is a shorter period of time, the third preset time is 0.2 seconds to 2 seconds, the third preset time is proportional to the first preset flow rate range, and the third preset time is proportional to the first preset color difference range.

[0144] In this embodiment, when the pressure change data to be tested is within the target pressure range and the vibration optical fiber data to be tested is within the target vibration amplitude range at the same time, by comparing the difference between the two drainage tube flow velocity data to be tested obtained after the third preset time and comparing the difference between the two drainage photoelectric sensor data to be tested obtained after the third preset time, the two differences are judged respectively, and the judgment results of the two differences are combined to predict the state of the surgical site and whether the drainage is unobstructed.
