Description

Technical Field

[0001] The present invention relates to the technical field of blood sugar monitoring, and in particular to a real-time blood sugar monitoring and hypoglycemia early warning system during hemodialysis. Background Art

[0002] The kidney is one of the important organs in our body. It is responsible for filtering waste and excess fluid from the blood and regulating electrolyte and acid-base balance in the body. However, when kidney function is impaired, these wastes and fluids will accumulate in the body. At this time, artificial dialysis devices are needed to remove waste, salts and excess water from the blood to help maintain balance in the body and ensure normal functioning of the body.

[0003] During dialysis, especially during hemodialysis, some patients may experience hypoglycemia. Changes in blood sugar during dialysis may be due to changes in waste removal and metabolic rate. Increased blood sugar during dialysis may be related to spontaneous eating during dialysis, stress response in the body, release of adrenaline, or use of glucose in the dialysate. Patients with advanced chronic kidney disease on dialysis, especially those who receive long-term hemodialysis or peritoneal dialysis, often experience hypoglycemia. The definition of hypoglycemia is that the blood sugar concentration is lower than the normal level, among which hypoglycemia is usually defined as a blood sugar concentration lower than 2.8mmol / L. The incidence of hypoglycemia is relatively high in dialysis patients, including dialysis treatment itself can cause hypoglycemia, the use of insulin or oral hypoglycemic drugs and malnutrition or loss of appetite, etc. Although this situation is relatively rare, since dialysis patients are originally accompanied by multiple symptoms, some mild hypoglycemia symptoms may be ignored or confused with other dialysis-related symptoms, which makes hypoglycemia difficult to detect and deal with in time. Therefore, a real-time monitoring system for blood sugar and hypoglycemia warning during hemodialysis is proposed. Summary of the invention

[0004] The purpose of the present invention is to reduce the attention fatigue caused by medical staff's real-time monitoring of patients' blood sugar, improve the accuracy of blood sugar monitoring during dialysis, and reduce or avoid the impact of hypoglycemia on patients during dialysis. A real-time blood sugar monitoring and hypoglycemia early warning system during hemodialysis is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] Real-time data of dialysis blood, through the blood glucose monitoring device connected to the hemodialysis machine, the blood glucose changes of dialysis patients can be obtained in real time;

[0007] The patient's physical data is obtained by obtaining the patient's basic physical data, including weight, age, height and blood sugar data;

[0008] Patient medication data and medical history: learn and record the patient's past medication and medical history;

[0009] The patient data transceiver compresses and transmits the acquired data through a data receiving device outside the hemodialysis machine;

[0010] Dialysis data storage, the process of storing processed and uploaded information and saving data in computer systems or other electronic devices;

[0011] The data processing module processes and transmits various data to monitor and process the patient's blood sugar in real time, and trains the time series model for the acquired information;

[0012] Blood sugar prediction data output: predict the patient's blood sugar during dialysis through a time series model and process the predicted data;

[0013] The real-time dialysis blood data is monitored in real time by a real-time blood glucose monitoring device externally connected to the dialysis machine, and the processed information is transmitted to the patient data transceiver. The patient's body data is transmitted to the patient data transceiver after the patient's basic body data is acquired. The patient's medication data and medical history are transmitted to the patient's data transceiver after the patient's past medical history and medication history are acquired. The patient data transceiver receives and decodes the signal through a real-time receiver, and then converts it into understandable data or information through a wirelessly transmitted signal and transmits it to a data processing module. The data processing module processes the incoming data and transmits the data to the blood glucose prediction data output. The data processing module packages and compresses the incoming data and transmits the data to the dialysis data storage for storage.

[0014] The above technical solution further includes:

[0015] The real-time data of dialyzed blood can provide more accurate treatment and monitoring for patients through the application of an external real-time blood glucose monitor on the dialysis machine, and the data is transmitted to the patient data transceiver. The patient's body data is obtained by collecting the patient's body temperature, weight, height and respiratory rate data, and the data is transmitted to the patient's data transceiver. The patient's medication data and medical history are obtained by understanding the patient's past medication history and the patient's medical history, and then the data is transmitted to the patient's data transceiver.

[0016] The patient data transceiver preprocesses the data, and packages and compresses the preprocessed data and transmits it to the patient data transceiver. After collecting and observing the patient data, the patient data transceiver transmits the data to data stabilization, and the data stabilization performs a differential operation on the data to eliminate or weaken the influence of the trend and seasonality of the data, and transmits the data to an autoregressive moving average model, and the autoregressive moving average model observes the linear relationship between the current observation value and the random error term, and transmits the data to parameter estimation, and the parameter estimation uses the maximum likelihood estimation method to estimate the parameters in the time series model, and transmits the data to model fitting and diagnosis, and the model fitting and diagnosis uses the estimated parameters to fit the time series model and diagnose the model, and transmits the data to prediction and evaluation, and the prediction and evaluation uses the fitted time series model to predict and determine the accuracy and stability of the model, and transmits the data to model adjustment and change, and the model adjustment and change adjusts and improves the model according to the prediction results and evaluation indicators.

[0017] The autoregressive moving average model is a time series analysis model used to describe trends and cyclical changes in time series data. The ARMA model combines the characteristics of the autoregressive model and the moving average model, where the autoregressive model represents the linear relationship between the current observation value and the past observation value, while the moving average model represents the linear relationship between the current observation value and the random error term. The ARMA model is usually expressed as a mathematical equation:

[0018] [X t =c+φ1X t-1 +φ2X t-2 +…+φ p X t-p +θ1ε t-1 +θ2ε t-2 +…+θ q ε t-q +ε t ], where: (X_t) represents the observed value of the time series at time (t); (c) is a constant term; (φ1, φ2,…, φ p ) are the coefficients of the autoregressive model, which represent the linear relationship between the current observation and the past (p) observations; (θ1,θ2,…,θ q ) is the coefficient of the moving average model, which represents the linear relationship between the current observation and the past (q) random error terms, (ε t ,ε t-1 ,...,ε t-q ) is a white noise error term. The estimation of the parameters of the ARMA model is usually performed using maximum likelihood estimation or other statistical methods. After the parameters are estimated, the ARMA model can be used to predict the blood glucose values ​​of the future time series.

[0019] The model fitting and diagnosis are commonly used concepts in statistics and machine learning, which are used to evaluate the degree of fit of the established model to the data and the effectiveness of the model. They involve testing whether the distribution of the residuals meets the assumptions, whether the model has multicollinearity or heteroscedasticity, and other issues. The fitting of the linear regression model can be expressed as:

[0020] [Y=β0+β1X1+β2X2+...+β p X p +ε], where (Y) is the dependent variable, (X1,X2,...,X p ) are independent variables, (β0,β1,β2,...,β p ) is the model coefficient, (ε) is the error term. When we want to predict a person's blood sugar (Y) by height (X_1) and weight (X_2), we can use a linear regression model to fit it and estimate the coefficients by the least squares method to obtain the best fitting linear relationship.

[0021] The blood glucose prediction data output predicts the patient's blood glucose changes through a time series model, and compares the predicted blood glucose data with the safe blood glucose range. When it is lower or higher than the safe blood glucose range, the patient's blood glucose prediction information alarm is triggered. The patient's blood glucose prediction information alarm reminds and warns medical staff to intervene in the patient's blood glucose in time through the patient's blood glucose alarm.

[0022] The blood sugar prediction data is output by comparing the blood sugar prediction data with the normal range, and the result of calculating the blood sugar concentration in the nutrient solution that needs to be regulated is output through the data processing module, and the result is transmitted to the medical staff for confirmation and regulation. After the medical staff confirms the regulation, the adjustment instruction is transmitted to the automatic regulation of glucose concentration. After receiving the instruction, the automatic regulation of glucose concentration regulates blood sugar. After confirming the regulation, the medical staff can manually modify the value after receiving the information, and transmit the instruction to the manual regulation of glucose concentration. The manual regulation of glucose concentration executes the blood sugar instruction modified by the medical staff.

[0023] The present invention has the following beneficial effects:

[0024] 1. In the present invention, the real-time blood glucose monitoring and hypoglycemia early warning system during hemodialysis is proposed. The real-time data of dialysis blood, the patient's physical data, the patient's drug data and the key data in the medical history are learned through a time series model, and then deployed through multiple trained models to predict the patient's blood glucose in real time during the dialysis process.

[0025] 2. In the present invention, the real-time blood sugar monitoring and hypoglycemia early warning system during hemodialysis is proposed. By comparing the predicted blood sugar with the normal blood sugar range, the patient's blood sugar prediction information alarm is issued for excessively high and low blood sugar. At the same time, the glucose concentration is automatically adjusted to facilitate timely and rapid regulation of the patient's blood sugar during dialysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 2

[0037] like Figure 1-2As shown, in the embodiment of the present invention, the patient data transceiver 4 pre-processes the data, and packs and compresses the pre-processed data to transmit to the patient data transceiver 4. After collecting and observing the patient data 12, the patient data transceiver 4 transmits the data to the data stabilization 13. The data stabilization 13 performs a differential operation on the data to eliminate or weaken the influence of the trend and seasonality of the data, and transmits the data to the autoregressive moving average model 14.

Model adjustment and change 18 adjusts and improves the model according to the prediction results and evaluation indicators. The autoregressive moving average model 14 is a model of time series analysis, which is used to describe the trend and cyclical changes in time series data. The ARMA model combines the characteristics of the autoregressive model and the moving average model, where the autoregressive model represents the linear relationship between the current observation value and the past observation value;

[0039] The moving average model represents the linear relationship between the current observation and the random error term. The ARMA model is usually expressed as a mathematical equation:
