Abstract
Description
Technical Field
[0001] The present invention belongs to the field of intelligent dialysis, and in particular relates to a novel intelligent dialysis machine system. Background Art
[0002] In the modern medical field, medical equipment is a key tool for diagnosis and treatment. The rationality of its parameter settings is directly related to the effectiveness of diagnosis and treatment. Taking the hemodialysis machine as an example, the blood flow rate is usually 200-400mL / min. It is adjusted according to the patient's vascular access and tolerance. The initial setting is generally 200-250mL / min, and gradually increased to 300-400mL / min. The dialysate flow rate is usually 500-800mL / min, with a standard setting of 500mL / min. It can be increased to 800mL / min as needed to improve dialysis efficiency. The ultrafiltration rate is usually 5-15mL / kg / h, and is adjusted according to the patient's dryness and blood pressure. The setting is based on weight and fluid retention, avoiding exceeding 15mL / kg / h to prevent hypotension and muscle cramps; the dialysis time is usually 3-5 hours / time, 3 times a week, and the standard dialysis time is 4 hours / time, 3 times a week, which can be adjusted according to the patient's specific situation; the dialysate temperature is usually 36.5℃ to 37.5℃, with the standard setting of 37℃, which can be fine-tuned according to the patient's body temperature and comfort; the dialysate is composed of 135-145mmol / L of sodium, 2.0-4.0mmol / L of potassium, 1.25-1.75mmol / L of calcium, 0.5-0.75mmol / L of magnesium, and 30-35mmol / L of bicarbonate. Adjustments are made based on the patient's electrolyte levels and acid-base balance to avoid electrolyte disturbances and acid-base imbalances;
[0003] Traditional medical equipment parameter setting methods mostly rely on manual operations and experience of medical staff. Although this method is feasible to a certain extent, it has obvious limitations. On the one hand, experience judgment lacks standardization and quantitative basis. The operations of different medical staff may lead to differences in parameter settings, which in turn affects the consistency of diagnosis and treatment; on the other hand, faced with complex and changeable clinical conditions, experience is difficult to fully cover and cannot accurately meet the personalized needs of each patient, resulting in low diagnosis and treatment efficiency and increased risks of misdiagnosis and missed diagnosis. Summary of the Invention
[0004] The purpose of the present invention is to overcome the defects in the background technology, such as the lack of standardization and quantitative basis for judgment, the operations of different medical staff may lead to differences in parameter settings, affecting the consistency of diagnosis and treatment, and facing complex and changeable clinical conditions, resulting in low diagnosis and treatment efficiency and increased risks of misdiagnosis and missed diagnosis, thereby realizing a new type of intelligent dialysis machine system.

[0098] The support vector machine uses radial basis kernel function and polynomial kernel to construct a support vector machine model to capture the nonlinear relationship between dialysis machine parameters and clinical conditions. The expression of the support vector machine model is:
[0099]
[0100] Among them, α i , α i * is the Lagrange multiplier, K(x i ,x) is the kernel function, b is the bias term;
[0101] The kernel function adopts radial basis function, and its specific form is:
[0102] K(x i ,x j )=exp(-γ||x i -x j || 2 ) (2)

[0104] The mathematical expression of the polynomial kernel is:
[0105]
[0106] Where: γ is the scaling factor that controls the weight of the monomial; r is the bias term (constant term) that increases the flexibility of the model; x i T is x i The transpose of ; d is the degree of the polynomial, which determines the dimension of the feature space after mapping;
[0107] The polynomial kernel maps the original features to a high-dimensional space through polynomial expansion.
[0108] Since the dimensions and value ranges of different characteristic parameters vary greatly, the blood flow value range may be between 100 and 300, while the ultrafiltration volume range is between 0.01 and 5, and the value range is relatively small. This difference will affect the training effect and convergence speed of the vector model. Therefore, the Z-score method is used to standardize the vector machine model data. The formula is:
[0109]
[0110] Among them, x is the original data, μ is the mean of the data, σ is the standard deviation of the data, and x′ is the standardized data.
[0111] The five-fold cross-validation method was used to adjust the hyperparameters of the above support vector machine.
[0112] Using stratified sampling method, vector machine model training and parameter adjustment:
[0113] Confusion matrix, precision and F1 score are used to evaluate the performance of the vector machine model in dialysis machine parameter adjustment:
[0114] Assuming the category labels are A, B, and C, the confusion matrix is as follows
[0115]
[0116] Diagonal elements : The number of correctly classified samples;
[0117] Off-diagonal elements : The number of samples that are actually class X but are misclassified as class Y;
[0118] Accuracy:
[0119]
[0120] The above formula represents the proportion of samples predicted to be A that are actually A in the F1 score:
[0121]
[0122] The performance of the trained vector machine model is evaluated using the test set. The results are as follows: Figure 6-9 As shown:
[0123] Model 1
[0124] like Figure 6 He Ru Figure 7 As shown in the two figures, the model shows excellent accuracy. The high learning curve shows both training and validation scores exceeding 0.9, and the overall confusion matrix accuracy is approximately 91% ((7+5+27) / 43). The majority class (good) is perfectly classified, with all 27 examples correctly predicted with no confusion. Generalization is stable, with convergence of training and validation scores in the learning curve and minimal fluctuation in the shaded area, indicating that the model is not overfitting. The best cross-validation scores are RBF and F1 scores of 0.91, respectively.
[0125] Model 2
[0126] like Figure 8 He Ru Figure 9 As shown in the two figures, the results that can be drawn from the two figures are that the accuracy of the second model is high. The learning curve shows that the training and validation scores are both 0.9+, and the overall accuracy of the confusion matrix is about 86.3% (number of correctly predicted samples / total number of samples = (14+52+116) / (14+1+2+52+15+0+8+116) = 182 / 211); the majority class (good) classification effect is good, all 116 samples are correctly predicted without confusion; the generalization ability is stable; the training and validation scores in the learning curve converge, and the shadow area fluctuates little, indicating that the model is not overfitting, and the training score is The value (red) was always higher than 0.93 and finally stabilized at 0.94±0.01 (narrow shaded area), indicating that the model had a strong ability to fit the training data. The validation score (green) increased from 0.78 to 0.87±0.02 (wide shaded area), indicating good generalization ability and no signs of overfitting. The best cross-validation score RBF was 0.88, the F1 score was 0.87, and the test set precision was 0.88. The support vector machine model showed good performance in the regression task of medical device parameters and clinical image quality scores, and can provide a reliable basis for parameter optimization.
[0127] The SHAP value is used to perform parameter sensitivity analysis on the support vector machine model. The SHAP value provides an explanatory value for each feature by calculating the contribution of each feature to the model prediction result. The larger the absolute value of the SHAP value, the greater the influence of the feature on the model prediction result. For model 1: Figure 10 As shown, ultrafiltration volume is the most important feature in the model prediction, directly affecting the patient's fluid balance management or complication risk; the significant impact of vascular access type reflects the importance of access stability on treatment efficacy. Vascular access types in this case include but are not limited to autologous fistulas; the number of dialysis sessions and age indicate that the frequency and age of treatment are key factors in long-term prognosis; the influence of treatment mode and dialysis duration is relatively small.
[0128] For Model 2: Figure 10 As shown, ultrafiltration volume and blood pressure parameters are the core features across the two types of analysis, suggesting the global importance of fluid management and blood pressure control in model prediction; the significance of tube access type and treatment mode may reflect the impact of long-term treatment strategies on patient prognosis; the impact of treatment mode and dialysis time is relatively small; Model 2 is used to predict complications (such as hypotension, infection) or treatment response in dialysis patients, and medical staff need to pay attention to monitoring and intervention of high SHAP value features; optimization of autologous fistulas (such as surgical quality and maintenance) can directly improve the clinical outcomes predicted by Model 2.
[0129] The dialysis machine is connected to a variety of sensors, including pressure sensors, flow sensors, temperature sensors, and blood component sensors, which are used to monitor the data parameters of the patient's blood purification.
[0130] When the patient starts dialysis, the dialysis machine obtains data from Model 1, determines the patient's condition, and adjusts the corresponding data parameter settings; during the patient's dialysis process, the patient's blood purification record data is obtained in real time through the sensors on the dialysis machine, and Model 2 is used to determine the current patient's dialysis status. The dialysis machine parameters are adjusted in a timely manner to ensure that the dialysis patient is in good condition.
[0131] When the present invention is used, it comprises the following steps:
[0132] S1. Check the hemodialyzer and tubing for damage, install the tubing according to aseptic principles, and pre-flush the dialyzer and tubing with normal saline to remove all air and gas;
[0133] S2. Set dialysis parameters, select appropriate vascular access, perform puncture, and secure the puncture needle; connect the arterial and venous ends, start the blood pump, and begin dialysis treatment;
[0134] S3. Continuously monitor the patient's response and the parameters of the dialysis machine during dialysis, and record important data during dialysis and the patient's response;
[0135] S4. After dialysis is completed, perform closed blood return according to existing standards and clean and disinfect the dialysis machine.
