Description

Technical Field

[0001] This invention relates to the field of intelligent control technology for medical devices, and in particular to an intelligent infusion system and intelligent infusion control method based on database dynamic feedback regulation. Background Technology

[0002] In clinical medical care, intravenous infusion is an important means of drug administration, nutritional support, and fluid replenishment. Its application covers multiple departments such as internal medicine, surgery, and emergency medicine. The traditional infusion process mainly relies on medical staff to manually adjust the drip rate knob of the infusion set and observe the patient's condition and the remaining amount of medicine through regular rounds. This mode is difficult to guarantee the real-time and continuous monitoring of infusion when there are many patients or when medical staff are busy. With the development of medical informatization and intelligence, rudimentary infusion pump devices have appeared on the market, which can achieve fixed-speed infusion. However, they still require manual preset parameters and lack the ability to dynamically respond to changes in the patient's physiological state and abnormalities in the infusion process, which cannot meet the refined and personalized needs of precision medicine for infusion control.

[0003] However, existing technologies lack dynamic control mechanisms supported by databases and mostly rely on single fixed parameter control. They cannot adjust infusion plans based on individual patient information such as age, condition, and allergy history, nor can they optimize current control strategies using historical infusion data. Furthermore, the linkage between monitoring and control is insufficient. They only have simple parameter monitoring functions, but the monitoring data is only used for local alarms and cannot be deeply analyzed and transformed into active control commands. This leads to reliance on manual intervention for abnormal handling. At the same time, infusion equipment mostly operates independently and cannot share data with hospital HIS systems and electronic medical record systems, which is not conducive to full traceability of the infusion process and medical quality control.

[0004] In summary, current infusion systems have significant shortcomings in personalized control and data-driven management, making it difficult to meet the complex and ever-changing infusion needs in clinical practice. Therefore, developing an intelligent infusion system based on dynamic feedback control from a database to achieve precise, automated, and information-based management of the infusion process has become an urgent technical problem to be solved in the field of medical equipment. Summary of the Invention

[0005] To address the technical problems existing in the prior art, the present invention provides the following technical solution:

[0006] On the one hand, an intelligent infusion system based on dynamic feedback regulation of a database is provided. This method is implemented by electronic devices. The system includes: an infusion terminal execution module, a multi-parameter monitoring module, a data transmission module, a central control server module, and a dynamic database module.

[0007] The infusion terminal execution module is used to receive infusion control commands sent by the central control server module, perform infusion speed adjustment and infusion start / stop operations, and provide feedback on the current infusion execution status information.

[0008] The multi-parameter monitoring module is used to collect patient physiological parameters, infusion tubing status parameters, and remaining drug volume parameters in real time during the infusion process, and convert the collected real-time parameters into digital signals.

[0009] The data transmission module adopts a wireless communication protocol to establish a data interaction channel between the infusion terminal execution module, the multi-parameter monitoring module and the central control server module, so as to realize real-time parameter uploading and control command downloading.

[0021] The intelligent decision-making unit has a three-level early warning mechanism. Based on the degree to which real-time parameters exceed the threshold, it is divided into level one, level two, and level three early warnings. Different levels of early warning correspond to different processing strategies, and the processing strategies are stored in the strategy rule base of the dynamic database module.

[0022] The instruction issuing unit is used to transmit the instructions calculated by the intelligent decision-making unit. The Level 3 early warning was converted into a control command and issued.

[0023] Furthermore, the three-level early warning mechanism of the intelligent decision-making unit is divided according to the following rules:

[0024] Level 1 warning: When When triggered, the system maintains automatic control and displays prompt information on the human-machine interface;

[0025] Level 2 warning: When or When triggered, the system maintains automatic control but activates an audible and visual alarm to alert medical staff. and These are the thresholds for first-level and second-level deviations, respectively. and These are the minimum and maximum infusion rates, respectively.

[0026] Level 3 warning: When a Level 2 warning is triggered and any real-time parameter uploaded by the multi-parameter monitoring module exceeds the threshold range of the corresponding real-time monitoring parameter in the dynamic database module, a Level 3 warning is triggered to issue an audible and visual alarm and a remote alarm.

[0027] Furthermore, when the intelligent decision-making unit triggers a level-three warning, the system suspends the infusion and automatically executes predefined emergency operations in the strategy rule base, including: locking the infusion pump and sending emergency alarm information containing the patient ID, abnormality type, and parameters to the monitoring center and the mobile terminals of medical staff.

[0028] Furthermore, the dynamic database module specifically includes:

[0029] The patient information database is used to store patients' age, weight, allergy history, and diagnostic results.

[0030] A drug knowledge base is used to store information on the standard infusion rate range, maximum / minimum safe rate, drug compatibility, and common adverse reaction characteristics of different drugs.

[0031] The historical case library is used to store complete infusion process data after desensitization, including real-time parameter time-series records for each infusion, triggered events, and control strategies adopted.

[0032] The strategy rule base is used to store regulation rules and anomaly handling strategies generated based on clinical guidelines and historical case data mining. The rules include physiological parameter safety thresholds, parameter change rate warning thresholds, and corresponding treatment procedures.

[0033] On the other hand, a smart infusion control method based on database dynamic feedback regulation is provided. This method is applied to a smart infusion system based on database dynamic feedback regulation. The specific steps of this method are as follows:

[0035] S200, Multi-parameter real-time monitoring: The multi-parameter monitoring module continuously collects the patient's physiological parameters, infusion tubing status parameters, and remaining drug volume parameters, and uploads them to the central control server module through the data transmission module;

[0036] S300, Dynamic Decision Making and Command Generation: The central control server module compares and analyzes the received real-time parameters with the loaded threshold range, and generates infusion control commands containing infusion rate information according to the preset control algorithm.

[0037] S400, Command Issuance and Closed-Loop Execution: The central control server module sends infusion control commands to the infusion terminal execution module through the data transmission module. The infusion terminal execution module adjusts the infusion status accordingly and feeds back the execution status to the central control server module.

[0038] S500, Cyclic Monitoring and Anomaly Handling: Cyclic execution of S200 to S400, while the central control server module continuously monitors the system status according to the anomaly handling strategy loaded in S100, and triggers an anomaly warning once the warning conditions are met.

[0039] On the other hand, an electronic device is provided, the electronic device comprising: a processor and a memory;

[0040] The memory stores computer-readable instructions, which, when executed by the processor, implement an intelligent infusion system based on database dynamic feedback control as described above.

[0041] On the other hand, a computer-readable storage medium is provided, wherein at least one instruction is stored therein, the at least one instruction being loaded and executed by a processor to implement an intelligent infusion system based on database dynamic feedback control as described above.

[0042] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0043] I. This invention uses a dynamic database module to store multi-dimensional data such as patient information, infusion plans, threshold ranges, and historical records. The central control server module calls these data and compares and analyzes them with real-time physiological parameters and infusion status parameters collected by the multi-parameter monitoring module to calculate the target infusion rate. Based on the target infusion rate and real-time monitoring parameters, it issues early warnings to ensure accurate monitoring of the control parameters and the individual patient's condition, and to keep the infusion rate always within the optimal range that adapts to the patient's physiological state, avoiding adverse infusion reactions caused by parameter errors or exceeding the physiological range.

[0044] Second, this invention collects real-time data of the entire infusion process through a multi-parameter monitoring module, and uploads it to the central control server module via a data transmission module with encryption. The server module performs deviation analysis based on database thresholds. When a parameter exceeds the safe range, the intelligent decision-making unit triggers a tiered warning and invokes anomaly handling strategies. At the same time, the infusion terminal execution module receives instructions from the server to adjust the infusion status and feeds back the execution results to the server. This linkage mechanism enables the system to complete anomaly identification, warning, and handling without manual intervention, shortening anomaly response time, reducing the inspection pressure on medical staff, and ensuring the safety and continuity of the infusion process.

[0054] Example 1

[0055] This embodiment provides an intelligent infusion system based on database dynamic feedback control. By constructing a closed-loop control system of "monitoring-analysis-decision-execution-feedback", it integrates five core modules: infusion terminal execution module, multi-parameter monitoring module, data transmission module, central control server module, and dynamic database module. It can dynamically adjust the infusion plan according to changes in the patient's physiological state, reduce manual intervention, improve the safety, accuracy and informatization level of infusion, realize intelligent control of the entire infusion process, and meet the refined and personalized infusion needs of clinical practice.

[0056] (1) Working principle and operation process of the infusion terminal execution module

[0057] The infusion terminal execution module receives infusion control commands from the central control server module, accurately executes infusion rate adjustment and infusion start / stop operations, and collects its own operating status information in real time and feeds it back to the central control server module, forming a closed-loop feedback at the execution level to ensure the consistency between infusion operation and control commands. This module is specifically composed of three parts: a stepper motor drive unit, an infusion pump body, and a status detection sensor. Each unit has a clear division of labor and works together to ensure the accuracy and reliability of infusion execution.

[0058] Stepper motor drive unit: Based on pulse signals, the stepper motor's rotation angle and speed are controlled, thereby adjusting the infusion rate of the infusion pump. This unit first receives control commands from the central control server module through the data transmission module. The commands contain motor speed parameters corresponding to the target infusion rate. The drive unit converts the target infusion rate into corresponding pulse signal parameters, which are indirectly related to the total infusion volume.

[0059] During operation, the stepper motor drive unit receives the target infusion rate update command from the central control server module in real time (when changes in the patient's physiological parameters cause the target rate to be adjusted), and dynamically adjusts the output pulse frequency: if the target rate increases, the drive unit increases the pulse frequency, which speeds up the stepper motor, increases the frequency at which the infusion pump squeezes the infusion tube, and increases the infusion rate; if the target rate decreases, the pulse frequency decreases, which slows down the motor speed and the infusion rate.

[0060] Status detection sensors: These sensors are used to collect real-time operating status data of the infusion pump body, ensuring the monitorability of the infusion process. They include a position sensor, a speed sensor, a pressure sensor (local), and a liquid level auxiliary sensor. The position sensor is installed at the pump head drive mechanism to detect the actual rotation position of the stepper motor, determining whether the infusion pump is in "standby," "running," or "paused" state, avoiding positional deviations caused by motor step loss. The speed sensor is connected to the stepper motor output shaft, collecting the actual motor speed in real time and converting the speed data into a digital signal, which is then fed back to the central control server module. This signal is compared with the target speed of the drive unit. If the deviation exceeds the allowable range (e.g., ±5%), a "speed deviation warning" is triggered, indicating possible mechanical jamming or drive failure. The local pressure sensor is installed near the infusion tube outlet to detect the real-time pressure of the medication output. If the pressure suddenly increases (e.g., due to infusion tube blockage) or suddenly decreases (e.g., due to infusion tube rupture or medication depletion), an abnormal pressure signal is immediately generated. The liquid level auxiliary sensor (if integrated) uses infrared or ultrasonic principles to assist in detecting the presence of medication in the infusion tube, preventing empty pump operation.

[0061] During overall operation, the workflow of the infusion terminal execution module is as follows: First, the central control server module issues an initial infusion control command (including the initial target infusion rate). The data transmission module decrypts the command and transmits it to the stepper motor drive unit. The drive unit converts the target rate into a pulse signal, controlling the stepper motor to drive the infusion pump body to start infusion. Simultaneously, the status detection sensor collects real-time status data such as motor speed, pump position, and outlet pressure. After converting the data into digital signals, it is uploaded to the central control server module through the data transmission module. The central control server module compares the actual status data with the command target data. If there is a deviation (such as the actual speed being lower than the target speed), the control command is adjusted and reissued to the drive unit until the actual status matches the target status. When a "pause" or "stop" command is received, or when the status detection sensor detects an anomaly, the drive unit immediately stops the motor, the infusion pump body stops infusion, and the abnormal status is fed back to the central control server module, awaiting further instructions (such as a restart command after troubleshooting).

[0062] (2) Working principle and operation process of multi-parameter monitoring module

[0063] The multi-parameter monitoring module comprehensively collects two types of key data during the infusion process: patient physiological parameters and infusion status parameters. It converts the collected analog signals into digital signals and uploads them to the central control server module through the data transmission module, providing data support for subsequent dynamic decision-making. This module is divided into a physiological parameter monitoring unit and an infusion status monitoring unit according to the different monitoring objects. The two types of units work independently and cooperate with each other to ensure the integrity and real-time nature of the collected data.

[0064] Physiological parameter monitoring unit: By collecting the patient's vital signs data in real time, it reflects the changes in the patient's physiological state during the infusion process. The core sensors include heart rate sensor, blood pressure sensor and blood oxygen saturation sensor. The three types of sensors monitor different dimensions of physiological indicators, which together constitute a comprehensive monitoring of the patient's physiological state.

[0065] During operation, the physiological parameter monitoring unit works as follows: First, medical staff select the corresponding sensor type and wearing position on the human-machine interface of the central control server module according to the patient's condition (such as age, weight, and diagnosis results), and load the normal threshold range of the patient's physiological parameters from the dynamic database. Then, after the sensor is worn, the unit performs an initial self-test to check whether the sensor is properly connected and whether the signal is stable. If the self-test passes, it begins to collect data in real time. During the collection process, the unit's built-in signal processing circuit filters and amplifies the raw signal, and then converts the analog signal into a digital signal through an analog-to-digital converter. Finally, the digital signal is encrypted by the data transmission module and uploaded to the central control server module. The upload cycle is synchronized with the sensor sampling cycle to ensure that the central control server module can obtain changes in the patient's physiological state in real time.

[0066] Infusion status monitoring unit: Through sensors installed in the infusion equipment and pipeline, it collects data on the equipment operation status and drug status in real time during the infusion process, reflecting whether the infusion is proceeding normally. It includes drip rate sensor, pressure sensor and drug level sensor. The three types of sensors monitor "infusion rate", "pipeline patency" and "remaining drug volume" respectively, which together constitute a comprehensive monitoring of the infusion process.

[0067] During operation, the multi-parameter monitoring module works as follows: After system startup, the physiological parameter monitoring unit and the infusion status monitoring unit initialize simultaneously, self-checking the sensor connection status and signal quality. If a sensor fault exists (such as signal interruption or data anomaly), a "sensor fault" signal is immediately generated and uploaded to the central control server module, triggering an "equipment fault warning." After the self-check passes, both units begin real-time data acquisition according to a preset sampling period. The acquired raw signals are processed (filtered, amplified, and converted from analog to digital) and converted into standardized digital signals. A timestamp is added to the digital signals to ensure data time consistency, and then the data is uploaded to the central control server module via the data transmission module. If data transmission is interrupted during the upload process, the module temporarily stores the data in a local cache and re-uploads the data after transmission resumes to avoid data loss. After receiving the data, the central control server module sends a "data reception confirmation" signal to the multi-parameter monitoring module. If the module does not receive the confirmation signal, it re-uploads the data to ensure the reliability of data transmission.

[0068] (3) Working principle and operation process of data transmission module

[0069] The data transmission module adopts a wireless communication protocol to establish a two-way data interaction channel between the infusion terminal execution module, the multi-parameter monitoring module, and the central control server module, realizing "real-time parameter uploading" and "control command downloading" while ensuring the security, real-time performance, and reliability of data transmission. Data uploading mainly includes the multi-parameter monitoring module uploading real-time parameters to the central control server module and the infusion terminal execution module uploading status data to the central control server module.

[0070] (4) Working principle and operation process of the central control server module

[0071] The central control server module receives real-time parameters uploaded by the multi-parameter monitoring module, compares and analyzes data from the dynamic database module, generates infusion control commands (such as target infusion rate) through intelligent algorithms, and sends them to the infusion terminal execution module. At the same time, it triggers graded early warning signals based on the deviation between real-time parameters and thresholds, realizing "data-driven dynamic decision-making". This module consists of three parts: a data preprocessing unit, an intelligent decision-making unit, and a command issuing unit. Each unit works together to ensure the accuracy, timeliness, and safety of the decision-making.

[0072] Data preprocessing unit: Standardizes multi-source real-time monitoring data (from physiological parameter monitoring unit and infusion status monitoring unit), eliminates data noise, unifies data format, and achieves data alignment, providing high-quality "data input" for intelligent decision-making unit and avoiding decision bias caused by raw data quality issues. The data preprocessing unit stores the integrated patient status vector in dynamic database module for easy subsequent query and retrospective analysis.

[0073] The intelligent decision-making unit compares and analyzes the patient state vector generated by the data preprocessing unit with the data (threshold range, historical cases, drug characteristics) in the dynamic database module. It calculates the target infusion rate using an adaptive control formula and triggers graded early warnings based on parameter deviations, achieving "personalized and dynamic infusion control decision-making." The target infusion rate is calculated as follows: ,in, The initial baseline rate is retrieved from the dynamic database module based on patient information and drug knowledge base. , Current physiological parameter monitoring values With target value deviation, The rate of change of physiological parameter deviation, and The adaptive weighting coefficients are dynamically calculated by the intelligent decision-making unit by querying successful control records in similar scenarios in the historical case database. The intelligent decision-making unit has a three-level early warning mechanism, categorized into Level 1, Level 2, and Level 3 early warnings based on the degree to which real-time parameters exceed thresholds. Different levels of early warning correspond to different handling strategies (stored in the strategy rule base of the dynamic database). Its core purpose is "tiered response and rapid handling" to avoid risks caused by untimely anomaly handling. The rules for the three-level early warning mechanism are as follows:

[0074] Level 1 warning: When When triggered, the system maintains automatic control and displays prompt information on the human-machine interface. The trigger time, trigger reason, handling measures, and control results of the first-level warning are recorded in the dynamic database module for easy subsequent traceability.

[0075] Level 2 warning: When or When triggered, the system maintains automatic control but activates an audible and visual alarm to alert medical staff. and These are the thresholds for first-level and second-level deviations, respectively. and These are the minimum and maximum infusion rates, respectively.

[0076] Level 3 warning: When a Level 2 warning is triggered and any real-time parameter uploaded by the multi-parameter monitoring module exceeds the threshold range of the corresponding real-time monitoring parameter in the dynamic database module, a Level 3 warning is triggered to issue an audible and visual alarm and a remote alarm.

[0077] (5) Working principle and operation process of dynamic database module

[0078] The dynamic database module stores basic patient information, preset infusion plan data, historical infusion record data, real-time monitoring parameter threshold range data, and anomaly handling strategy data. It supports real-time data updates and queries, providing comprehensive and accurate data support for the central control server module's decision-making. It also enables end-to-end data traceability of the infusion process. Based on different data types, this module is divided into four sub-databases: a patient information database, a drug knowledge base, a historical case database, and a strategy rule base. These sub-databases are interconnected and share data, forming a complete database system.

[0079] The patient information database is a sub-database that stores individual patient data. Its working principle is to obtain and store patients' basic and clinical information by connecting with the hospital's HIS system and electronic medical record system, providing patient-level data support for the development of personalized infusion plans and ensuring individualized infusion control.

[0080] The drug knowledge base is a sub-base that stores drug characteristic data. Its working principle is based on clinical guidelines, drug instructions, and pharmaceutical research literature to organize and store the characteristic parameters and usage rules of various infusion drugs, providing drug-level data support for the formulation and adjustment of infusion plans, and ensuring the safety and effectiveness of infusion regulation.

[0081] The historical case database stores and categorizes complete infusion process data after desensitization, providing experience references for intelligent decision-making in the central control server module, while also providing data support for clinical research and quality improvement, enabling continuous optimization of infusion protocols.

[0082] The strategy rule base is a sub-base that stores regulation rules and abnormal handling strategies. Its working principle is based on clinical guidelines and historical case data mining results to formulate and store various rules (such as physiological parameter safety thresholds and early warning triggering rules) and abnormal handling strategies (such as treatment procedures for different early warning levels) in the infusion process. This provides "rule-level" data support for the decision-making of the central control server module, ensuring the "standardization and safety" of infusion regulation.

[0083] In summary, the intelligent infusion system based on dynamic feedback control provided in this embodiment constructs a full-process control system of "data acquisition-preprocessing-decision-execution-feedback-optimization" through the collaborative work of the infusion terminal execution module, multi-parameter monitoring module, data transmission module, central control server module, and dynamic database module. This effectively solves the shortcomings of infusion systems relying on manual labor and existing infusion pumps lacking dynamic response and data-driven management. It enables the interoperability of infusion data and overall patient diagnosis and treatment data, providing more comprehensive support for multidisciplinary diagnosis and treatment decisions and promoting the deep integration of intelligent medical equipment and refined medical services.

[0087] Identity verification and data loading: Healthcare workers input or scan patient identity information.

[0088] Retrieve Personalized Plans: Based on the patient ID, the central control server automatically retrieves the patient's preset infusion plan, individualized safety parameter thresholds (such as target blood pressure, maximum / minimum allowable infusion rate, etc.), and abnormal handling strategies from the dynamic database of patient information and drug knowledge base.

[0089] System ready: The infusion terminal execution module (infusion pump) is initialized and awaits execution instructions.

[0101] Tiered early warning judgment: The intelligent decision-making unit compares real-time data with multi-level thresholds in the database to determine whether an early warning is triggered.

[0102] No warning: If everything is normal, proceed directly to the instruction issuance step.

[0103] Level 1 warning: If the parameter deviation exceeds the first threshold, the system will maintain automatic adjustment and only prompt medical staff to pay attention on the interface.

[0104] Level 2 warning: If the parameter deviation exceeds a larger second threshold or the calculation rate exceeds the limit, the system will trigger an audible and visual alarm while maintaining control, reminding medical staff to intervene and conduct an examination.

[0105] Level 3 warning: If a serious abnormality occurs (such as pipeline blockage or sudden drop in blood pressure), the system will immediately trigger the highest level alarm.

[0106] Phase Four: Command Issuance and Execution (S400)

[0107] Command issuance: The command issuance unit will encrypt and issue the final determined target infusion rate or shutdown command to the infusion terminal execution module.

[0108] Precise execution: The stepper motor drive unit of the infusion terminal execution module receives instructions and precisely adjusts the speed of the infusion pump to change the infusion rate.

[0109] Status feedback: The status detection sensor feeds back the latest execution status of the infusion pump to the central control server in real time, forming an execution closed loop.

[0110] Phase 5: Cyclic Monitoring and Learning (S500)

[0111] Continuous loop: The system repeats steps 4-14 at a very high frequency to form a closed-loop control, continuously monitors, analyzes, and adjusts to ensure that the infusion process is always in an optimal or safe state.

[0112] Recording and Learning: The data from this successful control process (including real-time parameters, decision instructions, and final results) will be anonymized and stored in the historical case library as a new case model to enrich system knowledge and optimize future decisions.
