[0095] Beneficial Effects
[0096] The present invention provides an intelligent prevention and management system for ICU sub-delirium syndrome based on a bundled intervention strategy. It has the following beneficial effects:
[0097] 1. The present invention adopts CNN and RNN. The system can process the multimodal physiological data of patients in real time and predict the occurrence of delirium in advance through time series analysis. This advance prediction can not only improve the response speed of medical staff, but also provide a critical time window for subsequent interventions. Multimodal data fusion combines multiple physiological signals such as heart rate, blood pressure, and brain waves. Through multimodal data fusion, the inaccuracy caused by a single signal is avoided, thereby improving the accuracy of the prediction. Compared with traditional single physiological signal monitoring, this multi-dimensional data fusion improves the perception of changes in patient status in a complex ICU environment. The data is pre-processed by a convolutional neural network. The system has a strong anti-noise ability and can accurately capture the patient's physiological changes even in a complex ICU environment, avoiding the false alarm problem in traditional monitoring systems.
[0098] 2. The present invention uses the Bayesian optimization algorithm. This module can generate personalized intervention strategies according to the individual situation of each patient to ensure the accuracy and effectiveness of the intervention measures. Compared with traditional fixed intervention measures, this dynamic optimization scheme can better meet the needs of different patients and reduce the situation of over-intervention or under-intervention. Through the real-time monitoring of the biofeedback device, the system can detect the patient's immediate response and quickly adjust the intervention measures. This feedback mechanism can improve the success rate of intervention and significantly reduce the recurrence rate of delirium in patients.
[0099] 3. The present invention adopts LSTM prediction, and the curve shows the optimization process of environmental data. Especially in environments with large changes in light, noise, etc., the system can adjust these parameters in advance to reduce interference with the patient's sleep, thereby reducing the risk of delirium caused by lack of sleep.
[0100] 4. The change of the Q value curve used in this invention reflects how DQN generates personalized rehabilitation plans based on the individual motor performance of the patient. Through feedback on the effects of different movements, the system can gradually identify the best rehabilitation path, thereby significantly shortening the rehabilitation cycle and improving the patient's rehabilitation efficiency.

[0165] SP5: Continuously monitor environmental changes and optimize and adjust based on feedback. The intelligent sleep management module dynamically optimizes the patient's sleeping environment by combining environmental sensors with edge computing technology. The core of this module is the light, noise, and temperature sensors, which monitor the environmental parameters in the ICU in real time. These data are processed locally by the edge computing unit to generate real-time environmental optimization suggestions, adjust factors such as light, noise, and temperature, and ensure that the patient is in the most suitable sleeping environment. The system combines the patient's electroencephalogram (EEG) signal and uses the LSTM network to analyze and predict the sleep state in time series. The LSTM network predicts the patient's optimal sleep cycle by analyzing the patient's historical sleep data, and adjusts the environmental parameters in advance to optimize the patient's sleep state. Through this prediction and dynamic adjustment, the intelligent sleep management module effectively improves the patient's sleep quality and reduces the incidence of delirium caused by lack of sleep. Compared with traditional environmental adjustment methods, this module improves the efficiency of environmental control through automation and real-time feedback, reduces external interference with patients' sleep, and provides patients with a more comfortable resting environment.
[0166] The emotion recognition and communication support module includes a camera and a microphone, which collect the patient's voice and facial expressions; the workflow of the emotion recognition and communication support module includes:
[0167] SP1: Start the camera and microphone to collect the patient's language and facial expression data;
[0168] SP2: Use convolutional neural networks to analyze facial expressions and identify the patient's emotional state;
[0169] SP3: Analyze the patient’s voice emotion through natural language processing;
[0170] SP4: Combine emotion recognition results with physiological status to generate personalized psychological support plans; the formula of emotion recognition and communication support module is as follows:
[0171]
[0172] E: emotional state score, used to measure the patient's current emotional state; w i : Weight coefficient, used to adjust the contribution of each emotional feature to the total score; f(x i ): characteristic function, which represents the specific value of each emotional characteristic of the patient;
[0173] SP5: Adjust the doctor-patient communication method in real time through feedback mechanism to optimize communication effect.
[0174] The multimodal physiological data acquisition module collects the patient's physiological data in real time by integrating physiological signal sensors such as heart rate, blood pressure and brain wave sensors. After being processed by the sensor, these data are transmitted to the data processor. The data processor is responsible for data preprocessing to remove noise and abnormal data. Next, the convolutional neural network (CNN) extracts features from the processed data and extracts key physiological feature signals from the raw data through multi-layer convolution operations. These feature data are then input into the recurrent neural network (RNN) and the long short-term memory network (LSTM) for time series prediction. The LSTM network is particularly good at handling long-term dependency problems in time series, allowing the system to predict the possibility of future delirium based on the patient's current physiological state and historical data. Through data collection, feature extraction and time series prediction, this module can provide accurate risk assessment for subsequent interventions. Compared with traditional monitoring methods, this module not only improves the accuracy of data processing, but also enhances the real-time analysis of dynamic physiological data, which is particularly suitable for use in complex ICU environments. By providing early warning of delirium risks, the system ensures that intervention measures can be effectively implemented before delirium occurs, thereby reducing the incidence of delirium in patients and improving treatment outcomes. Specific embodiment 2:
[0176] Based on the specific embodiment 1, the further clustered intelligent intervention module performs the following work through a multi-task learning model:
[0177] SP1: Receive physiological data input for different tasks, including medication management, rehabilitation management, emotional support, etc.
[0178] SP2: Process multiple intervention tasks in parallel through a multi-task learning model. The formula is:
[0179]
[0180] L: total loss function, representing the loss value of all tasks; λ i : The weight of each task, used to balance the priorities between different tasks; L i : The loss value of the i-th task, such as delirium management, motor rehabilitation, etc.
[0181] SP3: Adjust the weight of each intervention task according to the priority of different tasks;
[0182] SP4: Generate comprehensive intervention strategies and deliver them to corresponding modules;
[0183] SP5: Continuously optimize the intervention effect of each task through feedback mechanism.
[0184] The bundled intelligent intervention module combines the adaptive deep learning model with the Bayesian optimization algorithm to generate and dynamically adjust the individualized intervention plan for patients. First, the module obtains the patient's real-time physiological signals from the multimodal physiological data acquisition module. The adaptive deep learning model automatically adjusts the parameters of the model by analyzing the patient's physiological state to generate personalized risk assessment results. Subsequently, the Bayesian optimization algorithm calculates the utility value of different intervention measures based on the patient's current physiological data. Bayesian optimization calculates the optimal solution of different intervention plans through a formula, where P(y|x) represents the probability distribution of delirium in patients, and U(x) represents the utility value of each intervention measure. In this way, the system can select the most effective intervention plan. The system combines biofeedback technology to adjust the intervention strategy in real time according to the patient's immediate physiological response to ensure that the intervention measures match the patient's current state. Compared with traditional fixed intervention plans, this module significantly improves the accuracy and effectiveness of intervention by adjusting the strategy in real time, reduces the situation of over-intervention or under-intervention, and effectively reduces the risk of delirium. Specific embodiment three:
[0186] As shown in the figure, the workflow of the intelligent sleep management module further includes:
[0187] SP1: Start the long short-term memory network (LSTM) to predict the time series of sleep data;

[0189] SP3: Adjust environmental parameters (light, noise, temperature) in advance to optimize the patient's sleeping conditions;
[0190] SP4: Continuously optimize the environmental adjustment plan based on real-time sleep quality feedback;
[0191] SP5: Store sleep data in a central database for subsequent analysis and adjustment.
[0192] The intelligent drug management module optimizes the use of sedatives and analgesics by combining reinforcement learning with genetic algorithms. In actual operation, the drug injection pump first controls the injection rate of the drug according to the patient's immediate feedback, and the drug dosage sensor monitors the drug usage in real time and feeds back to the system. The system continuously adjusts the drug usage strategy through the reinforcement learning algorithm, and its core formula is Q(s,a)=Q(s,a)+α[r+γmaxQs-Q(s,a)]. In this process, the system adjusts the dosage of sedatives according to the patient's physiological data, r is the immediate return, reflecting the effect of the current medication, and γ is the discount factor, which is used to measure the impact of the current medication strategy on long-term health. The genetic algorithm reduces unnecessary drug side effects by optimizing the types and combinations of drugs. Through the selection, crossover and mutation operations of the genetic algorithm, the system selects the optimal solution from a large number of possible drug combinations. Compared with the traditional drug management system, this module can adaptively adjust the drug use strategy to ensure that patients use the most accurate medication during treatment, reduce drug side effects and improve the safety of treatment. Specific embodiment four:
[0194] As shown in the figure, the hardware components of the early movement and rehabilitation management module include:
[0195] Medication management server, which stores patients’ medication usage records;
[0196] The edge computing unit is responsible for the real-time control of drug injection;
[0197] Distributed computing architecture is used to optimize multi-patient medication management and adjust drug dosage and type in real time.
[0198] The early movement and rehabilitation management module combines convolutional neural networks (CNN) and deep Q networks (DQN) to achieve personalized customization and real-time adjustment of patient movement rehabilitation programs. The motion capture device monitors the patient's movement in real time, and CNN analyzes these data to extract movement features, such as joint angles and muscle activity. Then, DQN calculates the effect of the current rehabilitation action through the formula δ=r+γmax-Q(s,a), where r is the immediate reward, representing the patient's rehabilitation progress, and γ is the discount factor, which measures the impact of the current rehabilitation action on long-term recovery. The system continuously adjusts the rehabilitation plan through this formula, generates personalized rehabilitation strategies, ensures that the intensity of rehabilitation training is moderate, and avoids excessive or insufficient exercise. Through this dynamic adjustment, this module effectively shortens the rehabilitation cycle and significantly improves the quality of rehabilitation. Compared with traditional rehabilitation plans, this system can track the patient's rehabilitation progress in real time and adjust it according to its immediate status, thereby improving the patient's recovery efficiency and rehabilitation experience. Specific embodiment five:
[0200] As shown in the figure, in the multimodal physiological data acquisition module, the heart rate, blood pressure, and brain wave signals are extracted through the convolutional neural network (CNN) and the time series prediction is performed through the recurrent neural network (RNN). The curve shows the fluctuations of physiological signals such as heart rate and blood pressure, as well as the time series prediction results after RNN processing.
[0201] Time dependency processing: Through RNN’s time series processing capability, the curve can reflect the long-term dependency of the system on physiological data. RNN can predict future trends based on previous input states (heart rate, blood pressure, etc.), avoiding the limitation of traditional static models that cannot consider time correlation.
[0202] Multimodal data synchronization: During the synchronous collection of heart rate, blood pressure, and brain waves, the curve shows the joint analysis effect of these signals. Compared with traditional single signal analysis, the system improves the accuracy of overall prediction through the fusion of multimodal data.
[0203] Improved prediction accuracy: By extracting features through CNN and combining it with the long short-term memory (LSTM) of RNN, the system can reflect the efficient processing and prediction of complex physiological data in the curve, thereby accurately capturing future physiological changes. This technology improves the possibility of real-time prediction of delirium and provides a basis for timely intervention.
[0204] The bundled intelligent intervention module dynamically generates personalized intervention strategies through the Bayesian optimization algorithm. The curve shows the relationship between different intervention intensities and corresponding utility values, as well as the selection of the optimal intervention strategy point. Utility curve optimization: Through Bayesian optimization, the curve shows the process of the system calculating the optimal intervention strategy based on the patient's current physiological state. Compared with a fixed intervention plan, Bayesian optimization dynamically adjusts the intervention intensity according to the individual data of each patient and finds the optimal point of the utility value. In this way, the curve can show the continuous optimization of the intervention utility, reflecting the support for personalized intervention.
[0205] Efficient exploration and development: The optimal point on the curve shows the balance between exploration and development of Bayesian optimization. The algorithm can find a balance between exploring the effectiveness of different intervention intensities and developing the optimal strategy, which effectively reduces the uncertainty of the intervention plan and improves the efficiency of the intervention.
[0206] Reduce the risk of over-intervention: Through the dynamic adjustment of the utility value, the curve can reflect how the intervention intensity affects the patient's physiological response, thereby reducing the risk of over-intervention and under-intervention. The introduction of Bayesian optimization significantly improves the system's real-time prevention capability for delirium and can adjust intervention strategies under different physiological states.
[0207] The intelligent sleep management module combines LSTM to perform time series prediction and optimization of environmental parameters such as light, noise, and temperature. The curve shows how environmental parameters affect changes in sleep quality and the changing trend of LSTM prediction results.
[0208] Dynamic adjustment of environmental data and sleep status: The curve shows the dynamic relationship between environmental data such as light, noise and temperature and sleep quality. The LSTM model can reflect the time series prediction and processing capabilities of these environmental data through the curve, so as to adjust the environmental conditions in advance to ensure that patients get the best sleep quality.
[0209] LSTM time series processing capability: In the curve, LSTM can predict the patient's future sleep quality changes and adjust environmental parameters in real time by learning from historical environmental data. This long-term and short-term memory mechanism enables the system to cope with complex ICU environments and improves the ability to predict the patient's sleep cycle.
[0210] Reduce the impact of external interference on sleep: Through LSTM prediction, the curve shows the optimization process of environmental data. Especially in environments with large changes in light, noise, etc., the system can adjust these parameters in advance to reduce interference with patients' sleep, thereby reducing the risk of delirium caused by lack of sleep.
[0211] The early exercise and rehabilitation management module optimizes the rehabilitation plan through DQN (deep Q network). The curve shows the changing trend of the patient's immediate reward and cumulative Q value of the rehabilitation action.
[0212] Dynamically optimize rehabilitation plans: During rehabilitation training, the curve shows how DQN continuously optimizes rehabilitation strategies based on the patient's movement feedback. As the number of training sessions increases, the Q value in the curve gradually increases, indicating that the system finds the optimal sequence of rehabilitation movements through learning. Compared with fixed rehabilitation plans, DQN can dynamically adjust rehabilitation plans based on real-time feedback to ensure that the training intensity is moderate.
[0213] Feedback mechanism for long-term effects: DQN's reinforcement learning strategy ensures the effectiveness of the rehabilitation plan by balancing immediate rewards and long-term rewards. The curve shows the patient's progress in different rehabilitation actions. As the number of training sessions increases, the system gradually optimizes the actions, causing the Q value to continue to rise, indicating an improvement in the rehabilitation effect.
[0214] Personalized rehabilitation program generation: The changes in the Q-value curve reflect how DQN generates personalized rehabilitation programs based on the patient's individual motor performance. Through feedback on the effects of different movements, the system can gradually identify the best rehabilitation path, thereby significantly shortening the rehabilitation cycle and improving the patient's rehabilitation efficiency.
[0215] From the curves generated by each module, we can see that the application of each technology has brought significant improvement in results. Overall, the main technical improvements are reflected in the following aspects:
[0216] Real-time and dynamic: The curves of each module show that the system adapts to the patient's current state by dynamically adjusting strategies. This real-time and dynamic nature is the core advantage of the intelligent management system, especially when dealing with complex ICU environments and patients' changing physiological states, it can effectively intervene and manage in real time. Personalized optimization: Whether it is the intervention module, drug management module or rehabilitation module, the curve reflects that the system performs personalized optimization according to the individual state of each patient. Compared with traditional fixed schemes, personalized optimization can better improve the adaptability and intervention effect of the system. Algorithm-driven efficient optimization: By introducing advanced algorithms such as deep learning, Bayesian optimization, and reinforcement learning, the curve shows the efficient optimization capabilities of each module in prediction, intervention, and rehabilitation. These algorithms find the optimal intervention and rehabilitation schemes through continuous learning and iteration, thereby improving the operating efficiency of the entire system. Reduce errors and side effects: The curve also reflects that the system can effectively reduce delirium, drug side effects, and training errors during rehabilitation. Through continuous monitoring and feedback of the patient's physiological state, the system can accurately adjust the intervention and treatment schemes to achieve higher treatment safety and effectiveness.
[0217] The real-time monitoring and dynamic adjustment system can be dynamically adjusted according to the patient's real-time status to ensure that the intervention measures of each module match the patient's current situation and maximize the treatment effect. The personalized intervention and rehabilitation modules generate personalized intervention plans and rehabilitation training plans through different algorithms to ensure that each patient receives the most suitable treatment and rehabilitation strategy and improve the overall treatment efficiency. The intelligent drug management and intervention module that reduces errors and side effects can reduce drug side effects and unnecessary interventions through algorithm optimization to ensure that patients receive treatment in the safest state. To improve patient experience and rehabilitation effects, the system provides patients with better rehabilitation experience and psychological support through technologies such as virtual reality and emotion recognition, effectively improving the rehabilitation effect of patients.
