Description

Technical Field

[0001] The present invention relates to the technical field of intelligent emergency services, and in particular to an ACLS emergency comprehensive service management method based on virtual interaction, an ACLS emergency comprehensive service management device based on virtual interaction, an electronic device, and a computer-readable storage medium. Background Art

[0002] The ACLS (Advanced Cardiopulmonary Life Support) emergency procedure mainly includes the following steps: 1. Assess the patient's condition When a patient is suspected of cardiac arrest, medical personnel need to quickly assess the patient's consciousness and breathing status. If the patient is unconscious and not breathing, call the emergency team immediately and start cardiopulmonary resuscitation (CPR).

[0003] 2. Establishing intravenous access and administering medications While waiting for the emergency team to arrive, or while performing CPR, medical staff should prepare an ACLS kit and equipment for use if necessary. ACLS medications include epinephrine, atropine, lidocaine, amiodarone, etc. These medications can help restore the heart's pumping. Medical staff should select the appropriate medication for intravenous administration based on the patient's specific condition.

[0004] 3. Ensure airway patency and effective ventilation During the ACLS process, ensuring the patient's airway is patent and effectively ventilated is crucial. This may require intubation, the use of a simple respirator, or other ventilation methods to maintain the patient's oxygen supply.

[0005] 4. Electric Defibrillation Medical staff need to decide whether to perform defibrillation based on the patient's heart rhythm and electrocardiogram results. If the patient experiences arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia, medical staff will use a defibrillator to deliver an electric shock to restore normal heartbeat.

[0006] V. Continuous Monitoring and Evaluation During the implementation of the ACLS process, medical staff need to closely monitor the patient's vital signs, including blood pressure, heart rate, respiration, etc. Based on changes in the patient's vital signs, medical staff need to promptly adjust first aid measures and medication application.

[0007] 6. Eliminate reversible causes During the ACLS process, medical professionals also work to eliminate reversible causes of cardiac arrest. This includes identifying and addressing underlying diseases or conditions that may have contributed to the cardiac arrest, such as electrolyte imbalances and drug overdose.

[0008] 7. Post-resuscitation care If the patient's spontaneous circulation returns, medical staff will continue post-resuscitation care. This includes airway management, establishing an advanced airway, treating hypotension, performing blood tests, and performing electrocardiogram (ECG) monitoring. Further treatment measures, such as mild hypothermia and reperfusion therapy, may also need to be considered.

[0009] The entire ACLS emergency procedure requires close collaboration between medical staff to ensure that each step is executed quickly and accurately. By following the correct ACLS emergency procedure, the lives of cardiac arrest patients can be effectively saved.

[0010] However, in actual ACLS emergency services, medical staff often encounter the following difficulties in emergency services: First, the appropriate ACLS procedure must be considered for each patient, taking into account age, gender, and other factors. However, upon receiving a patient, medical staff in existing scenarios typically implement standard first aid procedures based on experience or hospital regulations, failing to quickly implement an ACLS procedure tailored to the patient's symptoms. Performing on-site calculations and analysis of the ACLS procedure would undoubtedly be time-consuming and delay emergency treatment.

[0011] Secondly, even if the ACLS process is implemented with reference to the ACLS process document (displayed on the PDA terminal carried by nurses for the convenience of medical staff), the text-based guidance method cannot provide medical staff with intuitive ACLS first aid guidance, and cannot enable medical staff (especially those with insufficient experience) to accurately implement ACLS first aid services.

[0028] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0029] The embodiment of the present invention provides an ACLS emergency integrated service management method based on virtual interaction, which can be implemented by an electronic device, which can be a terminal or a server. Figure 1 The flowchart of the ACLS emergency integrated service management method based on virtual interaction is shown. The processing flow of the method may include the following steps: S1. Pre-establish ACLS procedures adapted to different ages, genders, disease types, and in-hospital and / or out-of-hospital emergency care; S2. parse the ACLS process to obtain the emergency service content of each ACLS emergency node in the ACLS process; S3.

[0030] The present invention designs an ACLS distributed emergency comprehensive service management platform, which can perform distributed management of various ACLS emergency nodes, and can realize scenario simulation training, learning and assessment of corresponding ACLS nodes based on virtual interaction technology. When encountering corresponding emergency situations, the platform can execute simulated emergency operation simulations of corresponding nodes to guide medical staff to perform first aid and realize "advanced cardiovascular life support".

[0031] Can be combined with Figure 4 The application system of the present invention shown in the figure can be used to understand the description of the present method. Medical staff can communicate with the background through PDA to report information or query and call background resources. The hospital deploys an ACLS emergency VR platform separately, on which an ACLS VR emergency database is deployed, which stores VR emergency service tutorials for each ACLS emergency node corresponding to the ACLS process of different ages, genders, disease types, in-hospital emergency and / or out-of-hospital emergency. The VR emergency service tutorials for the corresponding ACLS emergency node (such as Figure 3 pediatric first aid VR video of a certain node shown in the figure) to the designated VR terminal.

[0032] The ACLS emergency VR platform can use the VR terminal communication ID reported by medical staff to request a communication link with the VR terminal and activate the VR terminal. This can be understood and implemented in conjunction with existing VR technology.

[0033] The implementation principle of the present invention will be described in detail below.

[0034] Preferably, S1, pre-establishing an ACLS process adapted to different ages, genders, disease types, in-hospital and / or out-of-hospital emergency care, including: Construct medical knowledge base data related to ACLS first aid; Generate keywords containing different ages, genders, disease types, in-hospital and / or out-of-hospital emergency care, build ACLS emergency care process retrieval logic, and combine keywords and retrieval logic to construct several prompt groups; Each group of prompts is injected into the preset LLaMA-2 13B model, and the LLaMA-2 13B model retrieves the ACLS process that meets the prompts from the medical knowledge base data; Each group of ACLS processes is stored in a structured manner.

[0035] Medical knowledge base data related to ACLS emergency care can be prepared by administrators or referenced from existing medical knowledge bases. LLM large language models can then be used to assist in construction, improving efficiency.

[0036] In the background, the ACLS process can be generated based on LLM (core module): 1. Construction of medical knowledge base: ‌Data Source Integration‌: Structured data: AHA 2023 ACLS Guidelines (PDF parsed into JSON), hospital emergency SOP (XML format), drug dosage database (SQL table); Unstructured data: medical literature (crawled from the PubMed API), emergency case text (desensitized and then NLP extracted key entities).

[0037] 2. Knowledge Graph Modeling: Neo4j was used to construct a four-dimensional graph of "disease-treatment-equipment-drug", and the relationships between nodes were weighted (e.g., "ventricular fibrillation → defibrillation" had a weight of 0.95, and "asthma → epinephrine" had a weight of 0.88).

[0038] 3. LLM process generation: Model fine-tuning: Based on the LLaMA-2 13B model, LoRA (Low-Rank Adaptation) technology is used to inject medical knowledge, and the proportion of fine-tuning parameters is ≤5%; Input prompt format: "Generate an ACLS process for {age} years old {sex} patient, in {in-hospital / out-of-hospital} setting, for {disease type}, including CPR cycles, medication dosage, and equipment operation steps." 4. Structured Storage The output process is stored in JSON Schema, including node ID, action type, parameters (such as compression depth, drug dosage), and dependencies (pseudocode), for example: { "node_id": "N3", "action": "electric defibrillation", "params": {"Energy": "200J", "Electrode location": "Right sternal border - apex of the heart"}, "prerequisites": ["Confirm pulseless ventricular fibrillation"], "next_nodes": ["N4(CPR)"]}.

[0039] 5. Technical Effects ‌Generation efficiency‌: Single process generation time is less than 3 seconds, and supports concurrent generation of 100+ processes; Accuracy: Verified by emergency experts from a tertiary hospital, the process complies with AHA guidelines with an accuracy rate of ≥96%; Coverage scenarios: 20,000+ combinations can be generated (e.g., “out-of-hospital cardiac arrest in an elderly male”).

[0040] like Figure 2 The ACLS process for pediatric first aid shown in the figure includes several ACLS first aid nodes, each of which has corresponding first aid service content. For example, at the "Confirm Scene Safety" node, first aid services include: checking responsiveness and calling for help; the first rescuer staying with the patient; and the second rescuer activating the emergency response system and obtaining an AED and first aid equipment.

[0041] Therefore, it is possible to parse and read the ACLS process under different conditions, and obtain the emergency service content of each ACLS emergency node in the ACLS process. This can be read through NLP natural language.

[0042] S2: ACLS process parsing and node extraction‌‌ This article uses the NLP parsing engine: Entity Recognition: Use the BiLSTM-CRF model to identify key entities (action, dosage, equipment) in the process text; Dependency analysis: Extracting “action-parameter-condition” triplets (e.g., “IV push → epinephrine → 1mg”).

[0043] ‌Node structured mapping‌: Map the parsing results to a predefined JSON Schema and use the rule engine to verify the integrity of key fields (e.g. "CPR nodes must contain compression depth and frequency"). Parsing accuracy: F1-score reaches 0.93 (test set of 500 processes); Real-time performance: Single-process parsing takes less than 200ms.

[0044] Preferably, S3, based on virtual interaction technology, according to the emergency service content of each ACLS emergency node in the ACLS process, a corresponding VR emergency service tutorial is constructed and stored in a MySQL database to obtain an ACLS VR emergency database, including: According to the ACLS emergency service content, several ACLS emergency equipment models are prefabricated and interactive operation links are configured, and the ACLS emergency equipment models are stored in a database to obtain a 3D model library; Traversing the emergency service content of each ACLS emergency node, retrieving the model of the corresponding content from the 3D model library, and building a VR emergency service scene of the corresponding content based on the Unity HDRP engine, and automatically adjusting the scene according to the attribute parameters of the ACLS emergency node; According to a structured data format, the VR emergency service scenarios of various ACLS emergency nodes corresponding to different ages, genders, disease types, in-hospital emergency care and / or out-of-hospital emergency care are stored in a MySQL database, and the ACLS VR emergency database is obtained and deployed on the hospital's ACLS emergency VR platform.

[0045] This section uses the Unity HDRP engine to build the VR emergency service tutorial (that is, the VR videos of each node). ‌‌Implementation principle:‌ 1. 3D model library construction: Device Modeling: Use Blender to create high-precision models (≤50k polygons) that support interaction (such as detecting the angle of defibrillator electrode placement). ‌Material Optimization‌: Simulates the reflection characteristics of metal / rubber materials based on PBR (physical rendering) technology.

[0046] 2. Dynamic scene generation: Unity HDRP Pipeline Automatically adjust ambient lighting based on node attributes (e.g., dynamic daylight in an outdoor scene vs. shadowless lighting in an ICU); Scripted generation logic (example): void GenerateScene(ACLSNode node) { if (node.env == "outside the hospital") AddTerrain("car accident scene"); Instantiate(node.equipment_model, position, interaction_script); } .

[0047] 3. Interaction logic binding: Use the Unity Event system to link device operations with tutorial feedback (such as triggering a green light prompt when the electrode is correctly placed).

[0048] ‌MySQL database design‌:‌ The table structure optimization is shown in the following table‌: Table name Index fields use vr_tutorials age_group,disease_type Store tutorial IDs by age / disease category tutorial_nodes node_id,vr_scene_path Node and VR scene file path mapping Storage optimization: Using B+ tree index, query response time is less than 50ms. Storage effect indicator control: Rendering performance: 90 FPS @ 4K resolution (NVIDIA RTX 4090); Scene generation efficiency: Single scene build time < 10 seconds (pre-compiled shader); Storage capacity: 1TB database can accommodate 10,000+ tutorial scenes.

[0049] Preferably, S4, reading the emergency information (age, gender, disease type, in-hospital emergency and / or out-of-hospital emergency) in the patient's emergency medical record, generating a corresponding ACLS emergency retrieval instruction based on the emergency information and sending it to the ACLS VR emergency database, retrieving the VR emergency service tutorial that meets the ACLS emergency retrieval instruction and outputting it, including: Medical staff use PDA terminals to collect emergency information from patients and report it to the emergency management background, which then creates the patient's emergency medical record and records the emergency information. The emergency management backend identifies and reads the emergency information in the patient's emergency medical record: age, gender, disease type, in-hospital emergency and / or out-of-hospital emergency, and sends it to the ACLS emergency VR platform; The ACLS first aid VR platform uses Elasticsearch to construct an ACLS first aid search instruction for an inverted index based on the first aid information: age, gender, disease type, in-hospital first aid and / or out-of-hospital first aid, and sends the instruction to the ACLS VR first aid database, requesting the ACLS VR first aid database to perform a tutorial search; After searching the ACLS VR first aid database, the VR first aid service tutorial that matches the first aid information is fed back to the ACLS first aid VR platform, and then forwarded to the designated VR terminal by the ACLS first aid VR platform.

[0050] Preferably, when medical staff collects the patient's emergency information through the PDA terminal and reports it to the emergency management background, it also includes: Report the device communication location ID of the designated VR terminal to the emergency management backend, which forwards it to the ACLS emergency VR platform. The ACLS first aid VR platform requests to establish a communication link based on the device communication ID of the designated VR terminal, activates the designated VR terminal, and notifies the terminal to wait for receiving the VR first aid service tutorial.

For example, scenario simulation training: Implementation plan ‌Multi-branch plot engine‌ based on patient status changes: If SpO2<90% for 10 seconds: Trigger the "endotracheal intubation" branch scenario elif the electrocardiogram shows ventricular fibrillation: Trigger the "Defibrillation" branch scenario.

[0075] Hospitals can use GAN to generate pathophysiological models and respond to operations in real time (such as simulating blood pressure curves after drug administration). This can be implemented in conjunction with the above-mentioned VR interaction. This solution uses the LLM+VR technology closed loop to achieve personalized, scenario-based and high-fidelity simulation of ACLS training. Pilot data from tertiary hospitals shows that the first-time rescue success rate of emergency teams has increased from 68% to 87%, which has significant clinical value.
