[0002] Continuous renal replacement therapy (CRRT), a crucial life-support method in critical care medicine, uses an extracorporeal circulation device to continuously remove metabolic waste and maintain water and electrolyte balance. It is widely used to treat patients with critical illnesses such as acute kidney injury and sepsis. The CRRT treatment process involves dynamic adjustments to multiple parameters, including blood flow, ultrafiltration rate, and replacement fluid composition. It also requires real-time adjustments to complex changes in the patient's physiological parameters (such as ionized calcium concentration and acid-base balance), placing extremely high demands on the accuracy and real-time performance of treatment parameters.
[0003] Traditional CRRT optimization processing systems often rely on statistical association models (such as regression analysis and machine learning classification algorithms) to train historical treatment data to establish the correlation between treatment parameters and physiological indicators. However, they can only reveal the correlation between variables and cannot analyze the causal mechanism. As a result, during the parameter adjustment process, it is impossible to distinguish between true causal effects and interference from confounding factors, causing unexpected treatment side effects. Summary of the Invention

Based on the spatiotemporal dynamics modeling of material transport and biochemical reactions using stochastic partial differential equations, a dynamic characterization of the treatment process is achieved. Through dimensionality reduction, denoising, and causal relationship map construction, the intervention effect of treatment parameters on physiological indicators is quantified. Combined with model predictive control and deep reinforcement learning, a treatment plan with both clinical safety and individual adaptability is generated. Real-time control and model iteration are achieved through an edge-cloud collaborative architecture, thereby clarifying the true action path of treatment parameters and physiological indicators through the causal map, avoiding decision-making bias caused by confounding factors. With the help of stochastic partial differential equation modeling and deep reinforcement learning, the model's adaptability to individual differences and the real-time performance of parameter adjustment are simultaneously improved, achieving scientific analysis and precise intervention of causal relationships during CRRT treatment.

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please see the attached Figure 1 The embodiment of the present invention provides an artificial intelligence-based CRRT data comprehensive acquisition and optimization processing system, including: Acquisition and calibration module: used to collect CRRT equipment parameters, physiological signals and laboratory test data to form multi-source data, and perform time alignment and spatial calibration on them to obtain calibration data; the acquisition and calibration module includes an acquisition unit, a communication unit and a calibration unit. The acquisition unit is used to collect CRRT equipment parameters, physiological signals and laboratory test data through a three-level sensor network to form multi-source data. The communication unit is used to perform real-time interaction of various data through HL7 FHIR interface protocol conversion. The calibration unit is used to perform time alignment and spatial calibration on multi-source data through hardware synchronous clock trigger sampling combined with fractional calculus interpolation algorithm to obtain calibration data.

[0025] Specifically, the acquisition and calibration module is used to establish a link for the collection, transmission, and spatiotemporal calibration of multi-source CRRT data, providing standardized input for the modeling and estimation modules. The acquisition unit collects data in layers through a three-level sensor network: the first level connects to the CRRT equipment to collect operating parameters such as pressure, flow, and replacement fluid concentration; the second level connects to physiological monitoring equipment to collect physiological signals such as electrocardiogram, blood oxygen, and pulse rate; and the third level connects to the laboratory information system to obtain test data such as blood gas analysis and ion concentration. This cross-device data collection covers all dimensions of CRRT treatment information, forming a multi-source heterogeneous data set.
[0026] Based on the HL7 FHIR interface protocol, the communication unit performs protocol conversion on the multi-source data output by the acquisition unit, breaking down the barriers of private protocols of equipment manufacturers and converting heterogeneous data into standardized medical data formats.

Simultaneously, based on a built-in spatial calibration model, it maps the spatially deployed differences in physiological signal sensors, such as surface electrodes and internal sensors, converting multi-source data into a unified spatial coordinate system. After calibration, the output calibration data has a unified sampling benchmark in the time dimension and coordinates are normalized in the spatial dimension. This provides a precise foundation for the modeling and estimation module to construct spatiotemporal dynamics models, effectively reducing model errors caused by data heterogeneity.
[0028] When the acquisition unit obtains the blood flow velocity signal of the CRRT device, the signal is distributed in a non-uniform time interval due to the device sampling mechanism and clinical fluctuations.

The parameter identification unit is used to optimize the parameters of the three-dimensional stochastic partial differential equation through variational Bayesian inference. The state estimation unit is used to solve the three-dimensional stochastic partial differential equation based on calibration data, estimate the state variables, and generate high-dimensional state data.

[0047] Specifically, the instruction generation module receives the basic treatment plan and personalized adjustment parameters output by the control strategy module, as well as treatment phase information from the acquisition and calibration module, such as the start-up and stabilization phase indicators. After weight fusion, safety verification, and coordinated execution, it generates device control instructions and drives model iteration. The weight fusion unit dynamically adjusts the weights of the basic treatment plan and personalized parameters based on the treatment progress monitored by the acquisition and calibration module, taking into account the device's operating time and the physiological signal trend determination phase. During the startup phase, the basic treatment plan's safety constraints are prioritized, receiving a higher weight. During the stabilization phase, personalized adaptation is gradually strengthened, increasing the weight of personalized parameters. The adjusted parameters are integrated and output as parameter adjustment instructions, facilitating the safety verification phase. Upon receiving the parameter adjustment instructions, the safety verification unit invokes the causal relationship graph of the fusion reasoning module to extract the causal constraints from the "treatment parameter → physiological indicator" link, such as the path from a sudden change in ultrafiltration rate to a decrease in ionized calcium. Combined with the clinical threshold set by the acquisition and calibration module, such as ionized calcium ≥ 1.0 mmol / L, it filters out abnormal instructions that violate causal logic or thresholds. The unit then integrates compliance instructions and generates device control instructions to ensure that the instructions comply with treatment safety and clinical standards. After receiving device control instructions, the collaborative architecture unit adapts to the HL7 FHIR protocol at the edge through the device interface of the acquisition and calibration module, driving the CRRT equipment to perform real-time control, such as adjusting the ultrafiltration rate and blood flow; synchronously collects real-time treatment data at the edge, such as device parameters and physiological feedback, and uploads it to the cloud; based on federated learning, the cloud associates the real-time data with the spatiotemporal dynamics model of the modeling and estimation module and the deep reinforcement learning strategy of the control strategy module for training, iteratively optimizes the model and strategy, realizes the coordination of edge real-time control and cloud model evolution, and improves the system's adaptability to CRRT treatment.
[0048] The acquisition and calibration module collects equipment parameters, physiological signals and laboratory data through a three-level sensor network, and combines hardware synchronous clocks with fractional-order calculus interpolation algorithms to complete time alignment and spatial calibration of multi-source data, thereby providing a high-precision standardized data foundation for subsequent modeling; the modeling and estimation module performs spatiotemporal dynamics modeling of material transport and biochemical reactions in CRRT treatment based on stochastic partial differential equations, and estimates state variables such as ion calcium concentration field and blood flow velocity field in combination with calibration data to generate high-dimensional state data that characterizes the dynamic characteristics of the treatment process, thereby realizing a mathematical description of the CRRT treatment mechanism; the fusion reasoning module performs manifold dimensionality reduction and adversarial denoising on the high-dimensional state data, constructs a causal relationship map between treatment parameters and physiological indicators through the PC algorithm, and uses Do-Calculus to quantify the intervention effect, thereby solving the problem of CRRT treatment. The control strategy module combines the spatiotemporal dynamics model with the causal intervention effect to construct a model predictive control framework to generate a basic treatment plan that meets clinical constraints, and then optimizes personalized parameters through deep reinforcement learning to achieve the coordination of treatment plan safety and individual adaptability; the instruction generation module integrates the basic plan and personalized parameters, and generates equipment control instructions after verification of causal constraints and clinical thresholds. Real-time control is performed at the edge through the edge-cloud collaborative architecture, and federated learning is used in the cloud to iteratively optimize models and strategies, thereby achieving scientific analysis and precise intervention of causal relationships in CRRT treatment, and solving the problem that traditional CRRT optimization processing systems cannot distinguish between true causal effects and interference from confounding factors during parameter adjustment, causing unexpected treatment side effects.
[0049] Please see the attached Figure 2 The method for all-around acquisition and optimization processing of CRRT data based on artificial intelligence is applied to the above-mentioned all-around acquisition and optimization processing system of CRRT data based on artificial intelligence, and includes the following steps: Acquisition and calibration: Collect CRRT equipment parameters, physiological signals, and laboratory test data to form multi-source data, and perform time alignment and spatial calibration on them to obtain calibration data; Modeling and estimation: Based on stochastic partial differential equations, a spatiotemporal dynamics model of material transport and biochemical reactions during CRRT treatment is constructed. State variables are estimated using calibration data to generate high-dimensional state data. Fusion reasoning: Perform dimensionality reduction and adversarial denoising on high-dimensional state data to generate low-dimensional feature vectors. Based on these low-dimensional feature vectors, a causal relationship map between treatment parameters and physiological indicators is constructed to calculate the intervention effect. Control strategy: A model predictive control framework is constructed based on the spatiotemporal dynamics model. The intervention effect is combined to generate a basic treatment plan that meets clinical constraints, and deep reinforcement learning is used to adjust its parameters in a personalized manner. Instruction generation: Integrates basic treatment plans and personalized adjustment parameters to generate device control instructions, performs real-time control at the edge through an edge-cloud collaborative architecture, and performs iterative training of spatiotemporal dynamics models and deep reinforcement learning strategies in the cloud.
[0050] Specifically, a three-level sensor network collects CRRT equipment operating parameters, physiological monitoring signals, and laboratory test data in a hierarchical manner, generating multi-source heterogeneous data. The communication unit utilizes the HL7FHIR interface protocol to complete data conversion and preliminary timestamp alignment. The calibration unit triggers multi-device synchronous sampling using a hardware-synchronized clock. For non-uniform dynamic data such as blood flow velocity fluctuations, a fractional-order calculus interpolation algorithm is introduced to fit the interpolated signal at the target time point, achieving multi-source data time alignment. Furthermore, based on a spatial coordinate mapping model, differences in sensor deployment are corrected for, completing data spatial calibration. The output of this calibration data provides precise, spatiotemporally synchronized input for subsequent modeling, eliminating interference from data heterogeneity.
[0051] After receiving the collected and calibrated calibration data, the discretization unit converts the transport and biochemical reactions of substances such as ionized calcium diffusion and citrate complexation during CRRT treatment into a weak form of three-dimensional stochastic partial differential equations. Using the finite element method, the space-time domain is discretized to construct a numerical solution framework. The parameter identification unit introduces variational Bayesian inference, sets prior distributions for parameters such as the diffusion coefficient and reaction rate, constructs a variational distribution approximation posterior, and uses the evidence lower bound formula for iterative optimization to match the model parameters with the statistical characteristics of the calibration data. The state estimation unit substitutes the calibration data as initial and boundary conditions and uses the stochastic finite element method combined with Euler-Markov time discretization to solve the dynamic evolution distribution of state variables such as the ionized calcium concentration field and blood flow velocity field, generating high-dimensional state data to characterize the spatiotemporal dynamics of CRRT treatment.
[0052] For the high-dimensional state data estimated by modeling, the dimensionality reduction unit uses a local linear embedding algorithm to first calculate the local reconstruction weights between samples. Then, based on these weights, the high-dimensional data is mapped to a low-dimensional manifold space, preserving the key state patterns of the CRRT process. The denoising unit constructs a conditional generative adversarial network, which uses noisy low-dimensional features as input. Combined with the physiological constraint priors estimated by modeling, it removes data noise through adversarial training between the generator and the discriminator, outputting an accurate low-dimensional feature vector. The causal modeling unit extracts treatment parameters and physiological indicators from the low-dimensional features, constructs a causal graph using the PC algorithm, clarifies the parent node relationship of the variables, and then uses the Do-Calculus formula to quantify the intervention effect of treatment parameter adjustment on physiological indicators, providing a causal basis for control strategies and avoiding misleading statistical associations.
[0053] Relying on the spatiotemporal dynamics model estimated through modeling and the intervention effects derived through fusion reasoning, the basic control unit constructs a model predictive control framework, sets the prediction and control time domains, and uses the predicted state vector, clinical reference trajectory, and control variables as inputs to optimize the cost function and generate a basic treatment plan that meets clinical constraints. The intelligent optimization unit incorporates deep reinforcement learning, using the deviation between the real-time state and the reference state, and the difference between the control variables and the basic plan as penalty terms. Complication indicators are combined to construct a reward function, iteratively optimize the control strategy, and personalize the basic plan based on individual patient characteristics to improve treatment adaptability.
[0054] The basic scheme and personalized parameters of the control strategy are received, and the weight fusion unit dynamically adjusts the weights of the two according to the treatment stage of the collected calibration feedback, and outputs parameter adjustment instructions. The safety verification unit calls the causal graph of the fusion reasoning and the clinical threshold of the collected calibration to filter out abnormal instructions that violate the causal or threshold and generate compliant equipment control instructions. The collaborative architecture unit performs real-time control on the edge side based on the device interface of the collected calibration through edge-cloud collaboration, and synchronously collects real-time data and uploads it to the cloud; based on federated learning, the cloud associates the real-time data with the spatiotemporal dynamics model estimated by modeling and the reinforcement learning strategy of the control strategy for training, iteratively optimizes the model and strategy, realizes the closed loop of edge control and cloud evolution, and continuously improves the system's optimization capabilities for CRRT treatment.
