[0002] Pregnancy is a special stage in which a woman's physiological state changes significantly. The physical health of a pregnant woman is directly related to fetal development and delivery safety. Among them, foot swelling (edema) is a common symptom in the second and third trimesters of pregnancy, usually caused by fluid retention, increased blood circulation pressure, or pregnancy-induced hypertension syndrome (such as preeclampsia). If abnormal swelling is not identified and intervention measures are not taken in time, serious complications such as deep vein thrombosis, organ function damage, and even premature birth may occur.

[0003] Therefore, the accurate monitoring of foot swelling in pregnant women and the dynamic analysis of related physiological indicators are one of the core requirements of obstetric health management.

Combining the swelling deviation value and threshold calculation, an objective quantitative assessment of the degree of foot swelling is achieved, which can more accurately distinguish normal, abnormal, and severe swelling states and dynamically generate warning signals.

[0016] Perform a ratio process on the swelling deviation value between adjacent monitoring nodes and the swelling deviation threshold value of adjacent monitoring nodes to obtain the foot swelling degree value of pregnant patients at adjacent monitoring nodes.

[0017] As a further solution of the present invention: The process of dividing the corresponding state of foot swelling time is as follows:

[0018] If the foot swelling degree value of pregnant patients at adjacent monitoring nodes meets the foot swelling degree range of pregnant patients within adjacent monitoring nodes, then record the time period corresponding to the adjacent monitoring nodes as the normal swelling period;

[0019] If the foot swelling degree value of pregnant patients at adjacent monitoring nodes does not meet the foot swelling degree range of pregnant patients within adjacent monitoring nodes, then record the time period corresponding to the adjacent monitoring nodes as the abnormal swelling period.

[0020] As a further solution of the present invention: The process of evaluating the swelling status of the feet of pregnant patients during the monitoring period is as follows:

[0021] Import the proportion of abnormal foot swelling time and the proportion of abnormal foot swelling degree of pregnant patients during the monitoring period into the MLP model to obtain the foot swelling degree characterization value of pregnant patients during the monitoring period;

[0022] And complete the evaluation of the swelling status according to the range of the foot swelling degree characterization value.

[0023] 5. The monitoring and analysis method based on the activities of pregnant women in obstetrics according to claim 4, characterized in that, record the foot swelling degree characterization value of pregnant patients during the monitoring period as ZB, and preset the limit values of the foot swelling degree characterization value of pregnant patients during the monitoring period as ZB1 and ZB2;

[0024] When ZB < ZB1, it means that the foot swelling of pregnant patients is in a normal swelling state during the monitoring period;

[0025] When ZB1 ≤ ZB < ZB2, it indicates that the foot swelling of the pregnant patient is in an abnormal swelling state during the monitoring period;

[0026] When ZB ≥ ZB2, it indicates that the foot swelling of the pregnant patient is in a severe swelling state during the monitoring period.

[0037] As a further solution of the present invention: if the blood pressure deviation degree value exceeds the preset blood pressure deviation degree interval, it indicates that the blood pressure state in the normal swelling time period and the blood pressure state in the abnormal swelling time period have a large deviation, and it is necessary to regulate the blood pressure of the pregnant patient;

[0038] If the blood pressure deviation degree value does not exceed the preset blood pressure deviation degree interval, it indicates that the blood pressure state in the normal swelling time period and the blood pressure state in the abnormal swelling time period have a small deviation, and it is necessary to identify other related factors;

[0039] Other relevant factors include the weight change of pregnant patients and the urinary protein change of pregnant patients.

[0053] Figure 2 is a block diagram of the monitoring and analysis system based on the activities of pregnant women in the obstetrics department according to an embodiment of the present invention. Detailed Embodiments

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Please refer to Figure 1 As shown, the present invention is a monitoring and analysis method based on the activities of pregnant women in the obstetrics department, including the following steps:

[0056] Divide a preset monitoring period into several monitoring nodes according to the time length, and scan the feet of pregnant patients at each monitoring node to obtain the foot projection information of the pregnant patients;

[0057] Among them, the monitoring period can be set according to the actual situation of the patient, including but not limited to 30 days, 60 days, or 90 days;

[0058] The monitoring node is to divide the monitoring period according to the same time length;

[0059] Exemplarily: Scanning the feet of pregnant patients is to use a three-dimensional foot laser scanner to scan the feet of pregnant patients to obtain the foot projection information of the pregnant patients;

[0060] Compare and analyze the foot projection information obtained at adjacent monitoring nodes of pregnant patients to obtain the non-overlapping area of the feet at adjacent monitoring nodes;

[0061] Among them, the non-overlapping area refers to the area where the foot projection information of pregnant patients at adjacent monitoring nodes does not overlap when the foot projections are overlapped.

[0062] Process the volume of the non-overlapping area to obtain the swelling deviation value between adjacent monitoring nodes;

[0063] Perform a ratio process on the swelling deviation value of adjacent monitoring nodes and the swelling deviation threshold of adjacent monitoring nodes to obtain the foot swelling degree value of the pregnant patient at adjacent monitoring nodes;

[0064] Among them, the swelling deviation threshold of the pregnant patient at adjacent monitoring nodes is set by medical staff based on experience, and relevant factors such as the patient's pregnancy period, weight, or blood pressure are comprehensively considered during the setting process.

[0065] Identify the foot swelling degree value of the pregnant patient at adjacent monitoring nodes. If the foot swelling degree value of the pregnant patient at adjacent monitoring nodes meets the foot swelling degree range within adjacent monitoring nodes of the pregnant patient, record the time period corresponding to the adjacent monitoring node as a normal swelling time period;

[0066] If the foot swelling degree value of the pregnant patient at adjacent monitoring nodes does not meet the foot swelling degree range within adjacent monitoring nodes of the pregnant patient, record the time period corresponding to the adjacent monitoring node as an abnormal swelling time period.

[0067] Sum up the durations corresponding to all abnormal swelling time periods within the monitoring period to obtain the abnormal swelling duration of the pregnant patient's foot swelling within the monitoring period;

[0068] Perform a ratio calculation on the abnormal swelling duration of the pregnant patient and the duration of the monitoring period to obtain the proportion of the abnormal foot swelling time of the pregnant patient within the monitoring period;

[0069] It should be noted that the larger the proportion of the abnormal foot swelling time of the pregnant patient within the monitoring period, the longer the abnormal foot swelling time of the pregnant patient within the monitoring period, and it also reflects the more serious the foot swelling degree of the pregnant patient;

[0070] Sum up the foot swelling degree values corresponding to all abnormal swelling time periods of the pregnant patient within the monitoring period to obtain the abnormal swelling degree value of the pregnant patient's foot swelling within the monitoring period;

[0071] Perform a ratio calculation on the abnormal swelling degree value of the pregnant patient and the total foot swelling degree value of the monitoring period to obtain the proportion of the abnormal foot swelling degree of the pregnant patient within the monitoring period;

[0072] Among them, the total foot swelling degree value of the monitoring period is the sum of the foot swelling degree values of all adjacent monitoring nodes within the monitoring period;

[0073] It should be noted that the larger the proportion of the abnormal foot swelling degree of the pregnant patient within the monitoring period, the more serious the abnormal foot swelling degree of the pregnant patient within the monitoring period;

[0074] Process the proportion of abnormal foot swelling time and the proportion of abnormal foot swelling degree of pregnant patients during the monitoring period, so as to realize the identification of the foot swelling of pregnant patients in two directions: the abnormal time dimension and the abnormal degree dimension. Specifically:

[0075] Obtain the historical data sample set for the foot swelling of pregnant patients, and perform standardization processing on the historical data sample set of the foot swelling of pregnant patients;

[0076] Use 70% of the sample data in the historical data sample set as the training set, and 30% of the sample data as the validation set;

[0077] Construct a multi-layer perceptron (MLP) model, input the sample data in the training set into the model for model training, and optimize the parameters of the model by minimizing the loss function;

[0078] Among them, the multi-layer perceptron (MLP) model includes an input layer (proportion of abnormal foot swelling time, proportion of abnormal foot swelling degree), a hidden layer, and an output layer (foot swelling degree characterization value);

[0079] Then, verify the constructed multi-layer perceptron neural network model after training through the validation set;

[0080] Use the trained model to predict the proportion of abnormal foot swelling time and the proportion of abnormal foot swelling degree of the current pregnant patient, and obtain the foot swelling degree characterization value;

[0081] Among them, using the proportion of abnormal foot swelling time and the proportion of abnormal foot swelling degree of different pregnant patients as the source data, construct the sample data of each pregnant patient.

[0082] Identify the foot swelling degree characterization value of pregnant patients during the monitoring period. Specifically, record the foot swelling degree characterization value of pregnant patients during the monitoring period as ZB, and preset the limit values of the foot swelling degree characterization value of pregnant patients during the monitoring period as ZB1 and ZB2, where ZB1 < ZB2;

[0083] It should be noted that: the limit values of the foot swelling degree characterization value of pregnant patients during the monitoring period, ZB1 and ZB2, are empirical values, obtained according to experience:

[0084] In the actual obtaining process, the staff identify the foot swelling degree level of pregnant patients according to the foot swelling degree characterization values of multiple groups of pregnant patients during the monitoring period, thereby obtaining a corresponding relationship between the foot swelling degree characterization value of a pregnant patient during the monitoring period and the foot swelling degree level of the pregnant patient. Furthermore, based on the foot swelling degree of the pregnant patient with foot swelling, the threshold value of the foot swelling degree characterization value is deduced and divided, so as to obtain the limit values of the foot swelling degree characterization value as ZB1 and ZB2. By comparing the limit values of the foot swelling degree characterization value, the identification of the foot swelling degree level of the pregnant patient corresponding to the foot swelling degree characterization value is completed;

[0085] When ZB < ZB1, it indicates that the foot swelling of the pregnant patient belongs to the normal swelling state during the monitoring period;

[0086] When ZB1 ≤ ZB < ZB2, it indicates that the foot swelling of the pregnant patient belongs to the abnormal swelling state during the monitoring period;

[0087] When ZB ≥ ZB2, it indicates that the foot swelling of the pregnant patient belongs to the severe swelling state during the monitoring period.

[0088] By obtaining the foot swelling degree characterization value of the pregnant patient during the monitoring period, the foot swelling of the pregnant patient is identified from two directions: the duration dimension and the swelling severity dimension, so as to have a clearer and more accurate judgment on the foot edema situation of the pregnant patient.

[0089] Based on the analysis of the physical state of the pregnant patient during the monitoring period, in this embodiment, the blood pressure of the pregnant patient is taken as an example:

[0090] Monitor the blood pressure of the pregnant patient during each normal swelling time period and each abnormal swelling time period. Specifically:

[0091] Divide the normal swelling time period into several blood pressure monitoring points according to the time length, and monitor the blood pressure of the pregnant patient at each blood pressure monitoring point to obtain the blood pressure monitoring group of the pregnant patient during the normal swelling time period;

[0092] Perform variance processing on the blood pressure values in the blood pressure monitoring group during the normal swelling time period to obtain the blood pressure variance value of the normal period;

[0093] When the blood pressure variance value of the normal period does not meet the requirements, mark the corresponding normal swelling time period as the non-curve construction time period;

[0094] When the blood pressure variance value of the normal period meets the requirements, mark the corresponding normal swelling time period as the curve construction time period;

[0095] By performing variance processing on the blood pressure values within the blood pressure monitoring group during the normal swelling period, it is possible to exclude abnormal blood pressure values during the normal swelling period. Among them, the abnormal blood pressure values may be due to inaccurate blood pressure measurement or significant blood pressure fluctuations on the same day;

[0096] Then, taking the monitoring time as the X-axis and the blood pressure value as the Y-axis, a plane coordinate system is constructed, and the blood pressure dynamic curves are constructed with the blood pressure values of the corresponding blood pressure monitoring points of the pregnant patient within each curve construction period (normal swelling period);

[0097] The blood pressure dynamic curves of each curve construction period are fitted to obtain the blood pressure dynamic characterization curve of the normal swelling period;

[0098] The abnormal swelling period is divided into several blood pressure monitoring points according to the time length, and the blood pressure of the pregnant patient is monitored at each blood pressure monitoring point to obtain the blood pressure monitoring group of the pregnant patient during the abnormal swelling period;

[0099] Variance processing is performed on the blood pressure values within the blood pressure monitoring group during the abnormal swelling period to obtain the blood pressure variance value of the abnormal segment;

[0100] When the blood pressure variance value of the abnormal segment does not meet the requirements, the corresponding abnormal swelling period is marked as a non-curve construction period;

[0101] When the blood pressure variance value of the abnormal segment meets the requirements, the corresponding abnormal swelling period is marked as a curve construction period;

[0102] By performing variance processing on the blood pressure values within the blood pressure monitoring group during the abnormal swelling period, it is possible to exclude abnormal blood pressure values during the abnormal swelling period. Among them, the abnormal blood pressure values may be due to inaccurate blood pressure measurement or significant blood pressure fluctuations on the same day;

[0103] Then, taking the monitoring time as the X-axis and the blood pressure value as the Y-axis, a plane coordinate system is constructed, and the blood pressure dynamic curves are constructed with the blood pressure values of the corresponding blood pressure monitoring points of the pregnant patient within each curve construction period (abnormal swelling period);

[0104] The blood pressure dynamic curves of each curve construction period are fitted to obtain the blood pressure dynamic characterization curve of the abnormal swelling period.

[0105] The blood pressure dynamic characterization curve of the normal swelling period and the blood pressure dynamic characterization curve of the abnormal swelling period are compared. Specifically:

[0106] The blood pressure dynamic characterization curve of the normal swelling period and the blood pressure dynamic characterization curve of the abnormal swelling period are plotted on the same plane coordinate system;

[0107] Seal the endpoints of the blood pressure dynamic characterization curve during the normal swelling period and the blood pressure dynamic characterization curve during the abnormal swelling period with line segments perpendicular to the X-axis;

[0108] Obtain the non-overlapping region of the curves corresponding to the blood pressure dynamic characterization curve during the normal swelling period and the blood pressure dynamic characterization curve during the abnormal swelling period;

[0109] Obtain the area value of the non-overlapping region of the curves, calculate the ratio of the area value of the non-overlapping region of the curves to the area threshold of the non-overlapping region of the curves, and obtain the blood pressure deviation degree value of the blood pressure dynamic characterization curve during the normal swelling period and the blood pressure dynamic characterization curve during the abnormal swelling period;

[0110] Among them, the area threshold of the non-overlapping region of the curves is set by the staff according to experience;

[0111] If the blood pressure deviation degree value of the blood pressure dynamic characterization curve during the normal swelling period and the blood pressure dynamic characterization curve during the abnormal swelling period exceeds the preset blood pressure deviation degree interval, it indicates that the blood pressure state during the normal swelling period and the blood pressure state during the abnormal swelling period have a large deviation, which means that the foot edema state of the pregnant patient has a large correlation with blood pressure changes, and it is necessary to regulate the blood pressure of the pregnant patient to reduce the foot edema of the pregnant patient.

[0112] If the blood pressure deviation degree value of the blood pressure dynamic characterization curve during the normal swelling period and the blood pressure dynamic characterization curve during the abnormal swelling period does not exceed the preset blood pressure deviation degree interval, it indicates that the blood pressure state during the normal swelling period and the blood pressure state during the abnormal swelling period have a small deviation, which means that the foot edema state of the pregnant patient has a small correlation with blood pressure changes, and it is necessary to identify other relevant factors;

[0113] Other relevant factors include, but are not limited to, the weight change of the pregnant patient, the urine protein change of the pregnant patient, etc., so as to realize the differential identification of the corresponding relevant factors of the pregnant patient during the normal swelling period and the abnormal swelling period.
