[0063] Figure 2 The following is an application architecture diagram of the TCM intelligent diagnosis system based on multimodal physiological signals provided in an embodiment of the present invention. Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0065] Understandably, in existing technologies, TCM intelligent syndrome differentiation usually only directly identifies and judges syndromes based on the collected TCM diagnostic indicator data, without comprehensively analyzing the impact of these indicators over time. It is a static and singular processing procedure, which is difficult to accurately reflect the patient's health status and can easily lead to a discrepancy between the syndrome differentiation results and the actual condition, thus affecting the accuracy of TCM syndrome diagnosis results.

[0066] To address the aforementioned issues, this invention discloses a TCM intelligent diagnostic system and method based on multimodal physiological signals. This system acquires TCM consultation data by recording consultations with target patients, identifying and determining TCM symptoms and multiple TCM indicator values, and selecting multiple relevant indicator values. It then collects multimodal physiological signals from the target patients; performs retrospective analysis on the multimodal physiological signals based on the TCM consultation symptoms to determine the symptom retrospective duration; optimizes the continuous influence of indicators according to the symptom retrospective duration and multiple relevant indicator values, calculating multiple optimized indicator values; and acquires Western medicine diagnostic data, combining it with the TCM consultation symptoms and multiple optimized indicator values ​​to perform a comprehensive diagnostic diagnosis. This system enables retrospective analysis of multimodal physiological signals, determining the symptom retrospective duration, optimizing the continuous influence of multiple relevant indicator values ​​according to the symptom retrospective duration, calculating multiple optimized indicator values, and then performing a comprehensive diagnostic diagnosis. This comprehensive analysis of the influence of indicators over time avoids static and singular processing, accurately reflects the patient's health status, and improves the accuracy of TCM syndrome diagnosis results.

[0067] Specifically, Figure 1 The flowchart of the TCM intelligent diagnosis method based on multimodal physiological signals provided in the embodiment of the present invention is shown.

[0068] In a preferred embodiment of the present invention, the TCM intelligent diagnostic method based on multimodal physiological signals specifically includes the following steps:

[0069] Step S101: Record the TCM consultation of the target patient, obtain TCM consultation data, identify and determine TCM consultation symptoms and multiple TCM indicator values, and select multiple relevant indicator values.

[0070] In this embodiment of the invention, a TCM (Traditional Chinese Medicine) consultation process involving observation, auscultation, inquiry, and palpation is performed on the target patient, and the consultation process is recorded to obtain TCM consultation data for the target patient. This data is then effectively extracted and processed to obtain valid consultation data. Subsequently, symptom identification is performed on the valid consultation data to determine the TCM consultation symptoms of the target patient. Furthermore, the valid consultation data is numerically processed to obtain multiple TCM indicator values. Based on the TCM consultation symptoms, correlation analysis is performed on the multiple TCM indicator values, and from these multiple TCM indicator values, multiple relevant indicator values ​​that are directly related to the TCM consultation symptoms are selected.

[0071] It is understandable that effectively extracting and processing TCM consultation data involves identifying and removing useless information from the data, including repetitive information and interjections.

[0072] Understandably, the numerical processing of TCM consultation indicators for effective consultation data involves two processes: indicator feature extraction and numericalization. Indicator feature extraction is the process of extracting features from image data, sound data, pulse data, temperature data, etc., in the effective consultation data. Examples include the color characteristics of the tongue coating, the waveform characteristics of the pulse, and the average temperature characteristics. Numericalization is the process of representing the extracted indicator features with numerical values ​​indicating the degree of health, such as the redness of the tongue, the thickness of the tongue coating, the pulse rate, the pulse strength, and the balance of questions.

[0073] Specifically, in another preferred embodiment provided by the present invention, the step of recording TCM consultations with the target patient, obtaining TCM consultation data, identifying and determining TCM consultation symptoms and multiple TCM indicator values, and selecting multiple relevant indicator values ​​specifically includes the following steps:

[0074] Record TCM consultations with target patients and obtain TCM consultation data;

[0075] The TCM consultation data is effectively extracted and processed to obtain effective consultation data;

[0076] The effective consultation data is identified to determine the TCM consultation symptoms and multiple TCM indicator values;

[0077] Based on the symptoms described in the TCM consultation, a correlation analysis was performed on multiple TCM indicator values, and multiple relevant indicator values ​​were selected from the multiple TCM indicator values.

[0078] Furthermore, the TCM intelligent diagnostic method based on multimodal physiological signals also includes the following steps:

[0079] Step S102: Collect multimodal physiological signals from the target patient.

[0080] In this embodiment of the invention, by identifying the physiological acquisition terminal of the target patient, a data access request is generated and sent to the physiological acquisition terminal of the target patient. The target patient can browse the data access request through the physiological acquisition terminal and perform an operation of agreeing or refusing. If the target patient agrees to the data access request, the data access permission of the physiological acquisition terminal can be obtained. Then, by determining the signal acquisition period, under the condition of having data access permission, the multimodal physiological signal corresponding to the signal acquisition period is extracted from the physiological acquisition terminal.

[0081] It is understood that, in this embodiment of the invention, the physiological data collection terminal for the target patient can be a smartwatch.

[0082] It is understandable that multimodal physiological signals include electrocardiogram (ECG) data, respiratory data, body temperature data, sleep data, etc.

[0083] Specifically, in another preferred embodiment provided by the present invention, the acquisition of multimodal physiological signals from the target patient specifically includes the following steps:

[0084] Identify the physiological data acquisition terminal for the target patient;

[0085] Generate and send a data access request to the physiological data acquisition terminal;

[0086] After the data access request is approved, data access permissions are obtained for the physiological data acquisition terminal;

[0087] Determine the signal acquisition period;

[0088] Based on the data access permissions, the multimodal physiological signals corresponding to the signal acquisition period are extracted from the physiological acquisition terminal.

[0090] Step S103: Based on the symptoms diagnosed by traditional Chinese medicine, perform retrospective analysis on the multimodal physiological signals to determine the symptom retrospective duration.

[0091] In this embodiment of the invention, by cleaning the multimodal physiological signals and removing abnormal data, cleaned physiological signal data is obtained. Then, the cleaned physiological signal data is standardized according to a preset data type standard to obtain standard physiological signal data. Subsequently, based on the symptoms of TCM diagnosis, the standard physiological signal data is backtracked to identify relevant abnormal data, and then the symptom backtracking time is determined based on the relevant abnormal data.

[0092] Understandably, by identifying relevant abnormalities in standard physiological signal data based on symptoms diagnosed in Traditional Chinese Medicine (TCM) and determining the time when these abnormalities first appeared, the duration of symptom retrospection can be determined.

[0093] Specifically, in another preferred embodiment provided by the present invention, the step of performing retrospective analysis on the multimodal physiological signals based on the symptoms diagnosed by traditional Chinese medicine consultation, and determining the symptom retrospective duration, specifically includes the following steps:

[0095] The physiological signal data from the cleaning process are standardized to obtain standard physiological signal data.

[0096] Based on the symptoms described in the TCM consultation, the standard physiological signal data is retrospectively identified to determine the relevant abnormal data.

[0097] Based on the relevant abnormal data, determine the duration of symptom retrospective analysis.

[0098] Furthermore, the TCM intelligent diagnostic method based on multimodal physiological signals also includes the following steps:

[0099] Step S104: Based on the symptom retrospective duration and multiple related indicator values, perform optimization processing on the continuous impact of the indicators, and calculate multiple optimized indicator values.

[0100] In this embodiment of the invention, by determining the optimization ratio data of the continuous impact of the indicators, which records different optimization ratio values, multiple optimization indicator values ​​are calculated according to the symptom retrospective duration, the optimization ratio data, and multiple related indicator values. Specifically, the calculation formula for the multiple optimization indicator values ​​is as follows:

[0101] ;

[0102] ;

[0103] ;

[0104] ;

[0105] ;

[0106] ;

[0107] in, The first optimization index value; This is the second optimized indicator value; , , and To optimize the ratio values ​​in the ratio data; The value of the first relevant indicator; This is the second relevant indicator value; and The initial time and current time of the symptom recall duration; , , and To calculate the median value.

[0108] It is understandable that multiple optimized indicator values ​​are based on multiple related indicator values, and are optimized over time to continuously influence them. This makes the multiple optimized indicator values ​​not only reflect the numerical value of the indicator itself, but also reflect the continuous impact of indicator anomalies.

[0109] Specifically, in another preferred embodiment provided by the present invention, the step of optimizing the continuous impact of indicators according to the symptom retrospective duration and multiple related indicator values, and calculating multiple optimized indicator values, specifically includes the following steps:

[0110] Determine the optimized proportion data for the sustained impact of the indicator;

[0111] Based on the symptom retrospective duration, the optimization ratio data, and the aforementioned related indicator values, multiple optimization indicator values ​​are calculated.

[0112] Furthermore, the TCM intelligent diagnostic method based on multimodal physiological signals also includes the following steps:

[0113] Step S105: Obtain Western medicine diagnostic data, and combine it with the TCM diagnosis symptoms and multiple optimized indicator values ​​to conduct a comprehensive dialectical diagnosis.

[0114] In this embodiment of the invention, Western medicine diagnostic data is obtained, and then relevant analysis is performed on the Western medicine diagnostic data based on the symptoms of traditional Chinese medicine consultation. Western medicine reference data related to the symptoms of traditional Chinese medicine consultation is extracted from the Western medicine diagnostic data. Then, the Western medicine reference data, the symptoms of traditional Chinese medicine consultation, and multiple optimized index values ​​are combined to conduct subsequent traditional Chinese medicine syndrome differentiation diagnosis.

[0115] Specifically, in another preferred embodiment provided by the present invention, the step of obtaining Western medicine diagnostic data, combining the symptoms from the traditional Chinese medicine consultation, and performing a comprehensive dialectical diagnosis includes the following steps:

[0116] Obtain Western medicine diagnostic data;

[0117] Based on the symptoms described in the TCM consultation, Western medicine reference data is extracted from the Western medicine diagnostic data.

[0118] The TCM diagnostic method is used to combine the Western medicine reference data, the TCM diagnosis symptoms, and the optimized index values.

The TCM consultation data is then effectively extracted and processed to obtain effective consultation data. Subsequently, symptom identification is performed on the effective consultation data to determine the TCM consultation symptoms of the target patient.

Based on the TCM consultation symptoms, correlation analysis is performed on the multiple TCM indicator values, and multiple related indicator values ​​that are directly associated with the TCM consultation symptoms are selected from the multiple TCM indicator values.
