Description

Technical Field

[0001] The present invention relates to the technical field of health data processing, and in particular to a pain data processing system for tumor patients. Background Art

[0002] With the rapid development of medical technology, data-driven patient management systems are becoming an increasingly important part of modern medicine. Especially in the pain management of cancer patients, traditional evaluation methods often rely on the subjective judgment of doctors or the self-reporting of patients, which is difficult to fully and accurately reflect the patient's true pain status. Therefore, the pain data processing system came into being, aiming to achieve an objective evaluation of the patient's pain status through multi-dimensional data collection and analysis, combined with physiological indicators and behavioral characteristics.

[0003] Chinese patent publication number CN114220543A discloses a method and system for evaluating the physical and mental pain index of tumor patients, and the method is specifically as follows: S1. Collect videos of patients during the observation period, intercept images to be analyzed, and extract facial images from the images to be analyzed; S2. Input the facial images into a pre-trained neural network physical pain and psychological pain recognition model for pain recognition, and obtain a first physical pain level and a first psychological pain level; S3. Automatically detect and track the trajectory of patient posture changes in the observation video, obtain the frequency of posture changes and the second physical pain level; S4. Patients conduct self-assessment through psychological pain test questions and physical pain test questions, and obtain the second psychological pain level and the third physical pain level; S5. Calculate the physical pain assessment value and the psychological pain assessment value according to the preset weight coefficient; It can be seen that this scheme does not consider the influence of multiple factors when performing pain recognition based on facial features and body posture changes, such as drug side effects, postoperative recovery, etc., and there is a problem of low accuracy in pain assessment of tumor patients. Summary of the invention

[0004] The object of the present invention is to provide a pain data processing system for tumor patients to solve at least one of the problems existing in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solutions: Tumor patient pain data processing system, including: Data collection module, used to collect target physiological data and behavioral data; A physiological monitoring module is used to construct a target heart rate abnormality index and a target breathing abnormality index according to the target heart rate and target breathing rate collected during the monitoring period; A judgment module is used to judge the target physiological state according to the construction results of the target heart rate abnormality index and the breathing abnormality index during the monitoring period; A behavior analysis module, for analyzing the pitch fluctuation state of the voice signal and the abnormality of the voice signal strength according to the target voice signal collected during the management period, and analyzing the target behavior state according to the analysis results of the pitch fluctuation state of the voice signal and the analysis results of the abnormality of the voice signal strength during the management period; The pain assessment module is used to classify the target pain level according to the analysis results of the target physiological state and the target behavioral state during the management cycle, and output the pain level to the user; The data analysis module is used to analyze the abnormality of the target skin conductance level according to the target skin conductance level collected during the management period, and adjust the target pain level classification process according to the analysis results.

[0011] Furthermore, the behavior analysis unit is used to analyze the target behavior state according to the analysis results of the pitch fluctuation state of the voice signal within the management period and the analysis results of the abnormality of the voice signal intensity. If (w1×r1+w2×r2) / 2×r0≤u0, the behavior analysis unit determines that the target behavior state of the current management period is normal; if (w1×r1+w2×r2) / 2×r0>u0, the behavior analysis unit determines that the target behavior state of the current management period is abnormal, w1 is the fluctuation weight, w2 is the intensity weight, r1 is the number of voice signals with abnormal fluctuation state within the management period, r2 is the number of voice signals with abnormal intensity within the management period, r0 is the number of target voice signals collected within the management period, and u0 is the preset behavior threshold.

[0012] Furthermore, the pain assessment module divides the target pain level into mild pain, moderate pain and severe pain according to the analysis results of the target physiological state and the target behavioral state during the management period, and outputs the target pain level to the user.

[0013] Furthermore, the data analysis module is provided with an abnormality analysis unit and a fluctuation analysis unit; the abnormality analysis unit is used to calculate the target skin conductance level average value DP collected during the management period, and compare the target skin conductance level average value DP with a preset conductance level threshold d0 to analyze the abnormality of the target skin conductance level. The abnormality of the target skin conductance level includes normal and abnormal. If the target skin conductance level of the current management period is abnormal, the first pain threshold is adjusted to L1', and the second pain threshold is adjusted to L2'.

[0014] Furthermore, the fluctuation analysis unit is used to calculate the fluctuation coefficient BD of the target skin conductance level based on the target skin conductance level collected during the management period, and compare the fluctuation coefficient BD of the target skin conductance level with a preset fluctuation threshold value YD to analyze the fluctuation state of the target skin conductance level. The fluctuation state of the target skin conductance level includes normal and abnormal. If the fluctuation state of the target skin conductance level in the current management period is abnormal, the preset conductance level threshold is adjusted to d0'.

[0015] The beneficial effects of the present invention are as follows: The system comprehensively covers the three key dimensions of physiological signals, behavioral signals and conductance signals, and conducts an overall assessment of the pain status of cancer patients, which is more accurate and scientific than single-dimensional assessment, and provides a dynamic adaptive adjustment mechanism.
