Abstract
Description
Technical Field
[0001] This invention relates to the field of data processing technology, and in particular to a method and system for monitoring patient intake and output based on flexible electronics and multi-parameter fusion. Background Technology
[0002] With the increasing demand for precision medicine and patient monitoring, medical institutions are placing greater emphasis on optimizing patient fluid management through multi-parameter monitoring to improve treatment safety. Current technologies typically collect patient monitoring parameters using a single electronic device and employ fixed threshold analysis or manual calculation methods to assess intake and output parameters to support clinical treatment or research decisions. Existing solutions lack comprehensive analysis of fluid volume parameters from multiple monitoring items and correlation modeling between disease types. This makes it difficult to accurately determine the correlations between monitoring items and optimize intake and output calculations. Commonly used isolated monitoring strategies are unsuitable for complex disease scenarios, resulting in insufficient accuracy in fluid management, a high risk of fluid imbalance, and limitations on patient treatment safety and efficacy.

[0171] As an optional embodiment, the first determining module determines the specific method of determining the multiple related monitoring devices corresponding to the monitoring item, including:
[0172] Determine the historical impact period corresponding to the monitoring item in the historical database; optionally, the historical impact period is used to characterize the time period during which the patient performed behaviors that led to changes in the fluid volume of the monitoring item.
[0173] For each monitoring device, obtain the historical work records corresponding to that monitoring device;
[0174] Calculate the similarity between the time period in the historical work record where the monitored quantity is greater than a preset threshold and the historical impact time period to obtain the correlation of the monitoring device.
[0175] From all monitoring devices, devices with a correlation greater than a preset correlation threshold are selected to obtain multiple relevant monitoring devices corresponding to the monitoring item.
[0176] As can be seen, through the above optional embodiments, by determining the historical impact time period corresponding to the monitoring item in the historical database, obtaining the historical working records of each monitoring device, calculating the similarity between the recording time period when the monitoring quantity exceeds the threshold and the historical impact time period as the correlation, and screening devices with a correlation exceeding the threshold as relevant monitoring devices, the accurate screening of relevant devices based on historical behavior time and monitoring data can be achieved, thereby improving the accuracy of patient fluid volume parameter assessment and treatment safety, and reducing the risk of fluid imbalance.

[0178] As can be seen, the above optional embodiments define the model architecture and training details of the fluid volume calculation model, so as to accurately calculate the precise fluid volume parameters, assist in achieving accurate intake and output assessment based on multiple parameters and disease correlation, improve the accuracy of patient fluid management and treatment safety, and reduce the risk of fluid imbalance.
[0179] As an optional embodiment, the second determining module determines the specific method of the correlation between the corresponding monitoring items based on the disease type of the target patient, including:
[0180] Determine the type of disease corresponding to the target patient;
[0181] Determine the historical medical records corresponding to the disease type in the preset database;
[0182] Based on the occurrence of monitoring items in historical medical records, the correlation between the corresponding monitoring items is determined.
[0183] As can be seen, through the above optional embodiments, by determining the disease type of the target patient and obtaining the corresponding historical disease records from the preset database, the correlation between monitoring items is determined based on the occurrence of monitoring items in the records, thereby realizing accurate correlation analysis of monitoring items based on disease type and historical data, improving the accuracy of patient fluid volume parameter calculation and treatment safety, and reducing the risk of fluid imbalance.
[0184] As an optional embodiment, the second determining module determines the specific method of the correlation between monitoring items based on the occurrence of monitoring items in historical medical records, including:
[0185] Screen out medical records that contain at least one monitoring item in their historical medical records;
[0186] For any two monitoring items, calculate the ratio of the number of abnormal records in all medical records where the parameters of the two monitoring items are abnormal to the total number of medical records, and obtain the proportional parameters corresponding to the two monitoring items.
[0187] For each abnormal record, calculate the normalized ratio between the parameter differences of the two monitoring items in the abnormal record and the normal parameters to obtain the difference similarity corresponding to the abnormal record;
[0188] Calculate the average of the difference similarity corresponding to all abnormal records to obtain the abnormal similarity between the two monitoring items;
[0189] The weighted sum of the proportional parameter and the anomaly similarity is calculated to obtain the correlation parameters corresponding to the two monitoring items.
[0190] As can be seen, through the above optional embodiments, by screening records containing at least one monitoring item in historical medical records, calculating the proportion of abnormal records with abnormal parameters in any two monitoring items to the total number of records, calculating the normalized ratio of the difference between the two monitoring item parameters for each abnormal record as the difference similarity, calculating the average of the difference similarities of all abnormal records to obtain the abnormal similarity, and then calculating the weighted sum of the proportion parameter and the abnormal similarity as the correlation parameter, a precise monitoring item correlation assessment based on abnormal co-occurrence and parameter differences can be achieved, improving the accuracy of patient fluid volume parameter calculation and treatment safety, and reducing the risk of fluid imbalance.
[0191] As an optional embodiment, the calculation module calculates the target patient's intake and output parameters according to the correlation of the monitoring items and the target patient's fluid volume parameters for each monitoring item in a specific way, including:
[0192] For any given monitoring item, calculate the average value of the correlation parameters between that monitoring item and all other monitoring items to obtain the key parameters of that monitoring item;
[0193] Calculate the correction weights that are proportional to the key parameters;
[0194] Calculate the product of the correction weight and the liquid volume parameter corresponding to the monitoring item to obtain the correction liquid volume parameter corresponding to the monitoring item;
[0195] Calculate the average value of the corrected fluid volume parameters corresponding to all monitored items to obtain the intake and output parameters corresponding to the target patient.
[0196] As can be seen, through the above optional embodiments, key parameters are obtained by calculating the average value of the correlation parameters between any monitoring item and other monitoring items. Correction weights are determined proportionally based on the key parameters. The product of the correction weights and the fluid volume parameters is calculated to obtain the corrected fluid volume parameters. The average value of the corrected fluid volume parameters of all monitoring items is then taken as the intake and output parameters of the target patient. This achieves accurate intake and output calculation based on correlation weighting, improves the accuracy of patient fluid management and treatment safety, and reduces the risk of fluid imbalance.
