Description

Technical Field

[0001] The present application belongs to the field of emergency transport monitoring and information sharing technology, and specifically relates to an emergency transport monitoring system and method. Background Art

[0002] During the entire process of emergency transfer from pre-hospital to in-hospital, the processing of patient monitoring data is particularly important. A good transfer environment, monitoring data and evaluation reports have a great impact on the patient's subsequent treatment.

[0003] During emergency transport, traditional technical means of transferring patient information usually include:

[0004] 1. Collect data during the transportation process by using paper records or manually filling out electronic records;

[0005] 2. At the end of the transport process, the data collected during the transport process are synchronized when the patient enters the hospital;

[0006] 3. Using video or voice calls to describe the patient's condition with the emergency center makes it difficult to reflect continuous changes in data;

[0007] 4. First aid personnel make a rough assessment of the current patient's condition based on past experience and take first aid measures;

[0008] 5. The equipment and the environment configuration in the ambulance need to be adjusted manually, and may not be in normal use when the patient gets on the vehicle.

[0009] The existing technical means have the following shortcomings:

[0010] 1. Inconvenient interaction and irregular medical records: Emergency personnel usually collect data during the transfer process in the form of paper records, and then synchronize them when entering the hospital. Irregular or missing nursing records during the transfer process may cause the receiving hospital to lack necessary reference information in subsequent treatment, affecting the treatment effect;

[0011] 2. Improper management of handover information: Patients’ medical records, treatment plans and other information may not be updated and shared in a timely manner, and information handover may be delayed or incomplete, affecting subsequent treatment;

[0012] 3. Untimely communication: Communicating with hospital medical staff about the patient's condition through video or voice calls. This communication method can easily lead to inaccurate communication between medical staff and the command center and hospital, which may cause delayed or incorrect information transmission;

[0013] 4. Inaccurate assessment: The assessment of the patient's condition by emergency personnel is highly subjective. Emergency personnel may lack the necessary professional training and the ability to respond to emergencies. They fail to conduct a comprehensive and accurate assessment of the patient's condition during transfer, which may lead to insufficient response after admission to the hospital and increase the difficulty of subsequent treatment;

[0014] 5. Inadequate equipment preparation: Inadequate preparation of in-vehicle equipment such as navigation, air conditioning, lighting, etc., and emergency equipment such as ventilators, monitors, defibrillators, etc., or failure to check their normal operating status in time may result in the inability to provide effective life support during the transfer process;

[0015] 6. Insufficient environmental comfort: The environment inside the car is not adjusted to an appropriate level in a timely manner, affecting the patient's medical experience and treatment effect.

[0016] 7. In the traditional emergency transport process, medical staff need to manually operate a variety of equipment, which has problems such as information islands, insufficient equipment monitoring, and limited data analysis and processing capabilities, making it difficult to meet the needs of modern medical emergency. Therefore, it is particularly important to develop an emergency transport monitoring system that can collect and transmit data in the emergency transport process in real time and accurately, provide comprehensive information support, and have data analysis capabilities, while providing a friendly interactive interface.

[0076] The in-vehicle environment data and vehicle operation data are collected from the vehicle system;

[0077] Real-time audio and video data comes from the vehicle-mounted audio and video equipment;

[0078] The alarm data comes from the monitoring control module;

[0079] The evaluation decision data comes from the evaluation decision module;

[0080] The report data comes from the evaluation and decision-making module.

[0081] The equipment communication submodule is mainly responsible for realizing the data communication between the equipment in the ambulance and the system communication submodule; the equipment communication submodule realizes the wireless connection and data transmission of the on-board system and the monitoring equipment in the ambulance through different communication methods; among them, the communication methods include but are not limited to Bluetooth, ZIGBEE, MQTT and other communication methods; it supports a variety of data formats and communication protocols (such as HL7, DICOM, etc.) to meet the communication needs of different medical devices; it adopts the device discovery and pairing mechanism to ensure the rapid connection and accurate identification of medical equipment and the monitoring system. The on-board system includes but is not limited to the navigation system, vehicle control system, safety system, on-board automatic diagnosis system and in-vehicle sensor system, etc., and the monitoring equipment includes but is not limited to monitors, ventilators, infusion pumps, etc.; the equipment communication submodule performs structured processing on the collected data and communicates with the data transmission interface provided by the system communication submodule to ensure that the information is transmitted in real time, accurately and efficiently.

[0082] The data storage submodule is mainly responsible for data storage and lifecycle management, data backup and recovery, data integration and sharing; the data storage submodule relies on high-performance storage media and adopts a hybrid storage architecture, that is, it combines relational databases and non-relational databases according to data types and businesses, formulates data retention policies based on the business value and legal requirements of the data, regularly reviews and optimizes data retention policies, ensures data compliance and efficiency, and migrates infrequently accessed data to lower-cost storage media. Establish an off-site backup center to store copies of data to prevent data loss caused by single point failures, and automatically perform regular backups according to data and business needs; establish a data warehouse or data lake, provide data interfaces and data exchange standards, support cross-departmental and cross-system sharing and utilization of data, clean, convert, integrate and store data from different sources, and provide a basis for data mining and analysis.

[0083] The information security submodule is mainly responsible for ensuring the information security of the data storage process and data of the emergency transport monitoring system, and preventing data leakage and illegal access. The information security submodule encrypts the transmitted data by using encryption technology to ensure the confidentiality of the data. It uses identity authentication and access control mechanisms to authenticate and manage the rights of users and devices accessing the system, record data access, modification and deletion operations, and detect abnormal behaviors in a timely manner. It ensures the security and privacy of data during the communication between systems and between systems and devices.

[0084] In the process of transfer, the destination of the ambulance may change according to the patient's condition, and there may be a temporary decision to send the patient to this hospital. The information security sub-module provides a dynamic registration and authentication method.

[0085] S1. Establish a unified authentication platform

[0086] Used to manage the identity information and authentication keys of all hospitals and ambulances using the system of this application. First, the unified authentication platform assigns a hospital number to the hospital accessing the system based on the hospital's unique identifier; an ambulance number is assigned to each ambulance based on the ambulance's unique identifier and the hospital number to which it belongs; the ambulance's unique identifier can be the license plate number; the hospital number and ambulance number are used for identity verification when accessing the system. A unique authentication key is generated for the ambulance based on the ambulance number, which is used for two-way encrypted authentication of the hospital and the ambulance when accessing the system.

[0087] S2. Ambulance applies for temporary authentication key

[0088] For vehicles temporarily transferred to non-corresponding hospitals, the following information must be included when applying for authentication: ambulance number, target access hospital code, authorization time required, and application reason. The unified authentication platform determines whether the ambulance is within the authorization scope of the platform based on the ambulance number; decides whether to grant authorization based on the rationality of the application reason, and sets a temporary authentication key validity limit based on the required time. Once expired, the ambulance needs to re-register and authenticate to ensure that the authentication key is only valid for this temporary transfer.

[0089] S3. Establish data communication channel

[0090] When the temporary authentication is passed, the system communication submodule establishes a temporary data communication channel between the target hospital and the ambulance. The target hospital can conduct a temporary cooperation with the ambulance and receive the monitoring data of the ambulance in real time. The target hospital can configure other functions according to the actual situation.

[0091] S4. Temporary transfer ends

[0092] When the temporary transfer is over, the data and reports during the temporary transfer are backed up and synchronized to the target hospital and the hospital to which the ambulance belongs. After the backup is completed, the data communication channel is closed and resources are cleaned up. Finally, the temporary authentication key generated by this dynamic registration and authentication is cancelled.

[0093] 2. Monitoring and control module; the monitoring and control module includes an environment monitoring submodule, an equipment monitoring submodule, a patient monitoring submodule, an alarm information submodule and an equipment control submodule; the monitoring and control module calculates the data collected by the data communication module to monitor and warn the in-vehicle first aid environment and the operation of the monitoring equipment, patient information and monitoring data; and can receive control instructions to adjust the equipment.

Environmental sensors include but are not limited to temperature sensors, humidity sensors, light sensors, air quality sensors, etc.; data fusion and processing technology are used to clean, verify and fuse environmental data to improve data accuracy and reliability; according to the preset environmental parameter thresholds, the environmental data is analyzed and judged in real time. When the environmental parameters exceed the thresholds, the alarm information submodule is triggered to alarm. Automatically adjust the equipment operation status according to the preset conditions.

[0095] The equipment monitoring submodule is mainly responsible for monitoring the working status of the medical equipment used in the emergency transfer process to ensure the stable operation of the equipment during the rescue process; it monitors the equipment data collected by the monitoring equipment in the ambulance through the data communication module, parses and processes the equipment data, and extracts key information for status judgment. Key information includes but is not limited to equipment operating status, fault codes, battery power, etc.; equipment data includes but is not limited to equipment network status, equipment information, operating hours, and equipment technical alarms, etc.; it can push abnormal data to the alarm information submodule in real time for alarm; and notify the equipment control submodule to perform corresponding processing, and the processing methods include but are not limited to starting backup equipment and backup power supplies, etc.; it can automatically adjust the equipment operating status according to preset conditions.

[0096] The patient monitoring submodule is mainly responsible for real-time monitoring of the patient's vital signs data, such as heart rate, blood pressure, blood oxygen saturation, body temperature, etc., and performing preliminary data analysis and processing. The patient's vital signs data is collected in real time through sensors worn by the patient. The sensors include but are not limited to heart rate sensors, blood pressure sensors, blood oxygen saturation sensors, etc. The patient monitoring submodule uses data filtering and denoising technology to pre-process the collected data to improve the accuracy and reliability of the data. According to the preset vital signs data threshold, the patient's vital signs data is analyzed and judged in real time. When the data exceeds the threshold, the alarm information submodule is triggered to alarm and notify the equipment control submodule to perform corresponding processing. Collect the patient's basic information, such as name, age, gender, etc. and connect to the hospital HIS to query past medical history.

[0097] The alarm information submodule mainly generates corresponding alarm information based on the abnormal data provided by the environment monitoring submodule, equipment monitoring submodule and patient monitoring submodule, such as excessive temperature in the car, equipment failure, abnormal patient vital signs, etc.; it can generate real-time alarm information; record and store abnormal information and alarm information in the log system, and summarize and organize the abnormal information in a report format according to the time when the abnormality occurred and the time when it was resolved, so as to facilitate subsequent analysis and processing. Multi-threading and asynchronous processing technology are used to ensure that multiple alarm information can be processed at the same time. Different alarm methods are used according to the type and urgency of the alarm information, including but not limited to sound alarm, light alarm, screen display, etc., to ensure that the rescue team can detect and process the alarm information in time.

The knowledge base submodule provides an interface for the language processing submodule to input data, the strategy generation submodule to request strategy output, and the report generation submodule to request data required for the report.

[0100] The language processing submodule is mainly responsible for the input of the patient's vital signs data or treatment needs by medical staff into the system through voice commands during the emergency transport process. The system can accurately identify and understand the voice commands of medical staff, quickly extract key information, and provide a basis for subsequent evaluation and strategy generation. Combined with natural language processing technology, it supports voice and text input, and uses natural language processing technology to perform semantic understanding and sentiment analysis on text data of medical staff's instructions, extracting key information, such as the patient's blood pressure, heart rate, respiratory rate and other vital signs data, as well as treatment needs or precautions.

[0101] The knowledge base submodule is mainly responsible for the process of emergency transportation. The system needs to quickly retrieve relevant knowledge based on the patient's vital signs data and chief complaint information, provide accurate evaluation results and recommended measures for medical staff, and assist medical staff in making accurate evaluations and decisions. By collecting and organizing first aid knowledge, disease diagnosis, treatment plans, etc., a comprehensive knowledge base is constructed: the emergency medicine knowledge base. According to the patient's vital signs data and chief complaint information, the knowledge in the knowledge base is used for query and reasoning to generate relevant evaluation results and recommended measures.

[0102] like Figure 2 As shown in the figure, the steps for building the emergency medicine knowledge base include:

[0103] S1. Clarify the objectives and scope of the knowledge base. For the emergency transport monitoring system, the knowledge base should cover key information such as emergency medical knowledge, equipment operation guidelines, patient monitoring standards, and emergency procedures. At the same time, it is also necessary to determine the update frequency and maintenance method of the knowledge base to ensure its timeliness and accuracy.

[0112] Knowledge representation is to represent the extracted knowledge in a structured way, such as ontology model, knowledge graph, etc., to facilitate subsequent query and reasoning.

[0113] S4. Knowledge base construction and verification, implementation methods include but are not limited to knowledge base design, data import, verification and testing.

[0114] Among them, knowledge base design refers to designing the storage structure, query interface and update mechanism of the knowledge base to ensure the efficiency and scalability of the knowledge base.

[0115] Data import is to import the extracted knowledge into the knowledge base, and perform data cleaning and deduplication to ensure the accuracy and consistency of the data.

[0116] Verification and testing involves verifying and testing the constructed knowledge base to ensure that it can accurately answer user queries and provide correct suggestions.

[0117] S5. Knowledge base maintenance and update, including but not limited to regular updates, user feedback, and technical support.

[0118] Among them, regular updates mean regularly updating the content in the knowledge base based on the latest medical research and clinical practice to ensure its timeliness and accuracy.

[0119] User feedback means collecting user feedback and suggestions to continuously improve and optimize the knowledge base.

[0120] Technical support means providing technical support and consulting services to help users solve problems encountered in the process of using the knowledge base.

[0121] According to the above technical solution, an embodiment is given. This embodiment implements a knowledge base question-answering system based on the Langchain development framework, including the following three core components:

[0122] Embedding Model:

[0123] The text input by the user through the language processing submodule is converted into a vector representation and the knowledge source is extracted and represented so that the retriever can perform efficient indexing and retrieval in the knowledge base. The present invention can select the same embedding model as the indexing part, such as FlagEmbedding, Ember, GTE or E5, to ensure the consistency and accuracy of the vector representation. Through the embedding model, the user's question is converted into a point in a high-dimensional vector space, which provides a basis for the subsequent generation of text content retrieval.

[0124] Retriever:

[0125] Based on the vector representation processed by the embedding model, the most relevant content is recalled from the knowledge base. The retriever can use efficient index structures and algorithms, such as inverted index and BM25, to quickly locate knowledge items related to user questions. Through the retriever, the system can quickly filter out the knowledge content that best matches the user's question and provide material for subsequent answer generation.

[0126] Large Language Model (LLM):

[0127] Generate accurate and fluent replies based on the content recalled by the retriever. The present invention can select open source LLM models, such as glm4-chat, llama-3.1, etc. These models have powerful text generation capabilities and context understanding capabilities. The LLM model can generate logical and easy-to-understand answers based on the context of the user's question and the content recalled by the retriever, providing users with timely first aid guidance.

[0128] As an improvement to the knowledge base of the emergency transport monitoring system, the present invention adds an abstraction layer on top of the large language model (LLM) and integrates a rule engine, which can support complex situations of knowledge base retrieval data and user input data, ensure that the knowledge base questions and answers comply with medical industry rules, and improve the effectiveness of emergency measures and patient safety.

[0129] The abstract layer is located above the LLM layer and is used to receive user input and convert it into a format that the LLM can understand. The abstract layer is also responsible for converting the output of the LLM into a format that is meaningful to the user, and for properly interpreting and verifying it. The rule engine is integrated in the abstract layer to further verify and correct the output of the LLM. The medical industry rule base is integrated into the rule engine, and these rule bases define the compliance and accuracy requirements of the knowledge base questions and answers. When the output of the LLM does not comply with the rules in the rule base, the rule engine will correct or reject it to ensure the accuracy of the question and answer. Based on the technical solution of the present invention, rule engines such as Drools, Easy Rules, and Aviator can be selected.

[0130] The strategy generation submodule is mainly responsible for automatically generating emergency transport strategies during the emergency transport process.
