Description

Technical Field

[0001] The present invention belongs to the technical field of emergency systems, and particularly relates to a on-site collaborative treatment system for cardiac arrest. Background Art

[0002] The golden rescue time for patients with cardiac arrest is 4 to 6 minutes, and it is crucial to take effective first aid measures during this period. However, the average arrival time of urban ambulances is usually 8 to 13 minutes, resulting in a first aid gap period before the arrival of medical staff.

[0003] Most of the people who first discover a patient after the onset of the disease are non-professionals. These non-professionals report through channels such as 120 and wait for professional medical staff to implement treatment, which easily misses the golden rescue time.

[0004] Currently, treatment equipment such as AEDs is configured in some public facilities such as large commercial areas and subway stations. However, due to cost issues, it is impossible to configure them densely. This makes it difficult to transport the appropriate treatment equipment to the patient's side in a timely manner when a first aid event occurs.

[0005] Due to the serious mismatch between the configured location of the AED and the place where cardiac arrest occurs, the coverage rate of the AED is low, and the average distance from the patient to the nearest AED is relatively far.

[0006] How to shorten the transportation time of treatment equipment and provide treatment operation information for non-professionals so that they can also perform rescues is a technical problem that needs to be solved currently. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a on-site collaborative treatment system for cardiac arrest in view of the above deficiencies in the prior art, which shortens the transportation time of treatment equipment, provides treatment operation information for non-professionals, strengthens the rescue quality to a certain extent, and thus improves the survival rate of patients.

[0008] To solve the above technical problem, the technical solution adopted by the present invention is: a on-site collaborative treatment system for cardiac arrest, including a database, a dispatching system, a collaborative client, a navigation beacon terminal, and a drone;

[0009] The database is used to store resource information, knowledge information, and three-dimensional navigation maps for treatment;

[0010] The dispatching system is used to command and control the drone and also send treatment tasks to the collaborative client;

[0011] The collaborative client is used to receive the treatment tasks sent by the dispatching system and send information on the analysis of the development trend of the tasks to the dispatching system;

[0012] The navigation beacon terminal is used to send the location information of the occurrence of the first aid event to the dispatching system, and play the treatment operation information in the form of voice and / or video when the first aid event occurs;

[0013] The drone is used to transport the treatment equipment to the location of the navigation beacon terminal according to the flight instruction of the dispatching system.

[0014] For the above-mentioned on-site collaborative treatment system for cardiac arrest, when the drone receives the flight instruction of the dispatching system, it transports the treatment equipment to the location of the navigation beacon terminal in an automatic navigation manner by using the built-in three-dimensional navigation map or the three-dimensional navigation map in the database.

[0015] For the above-mentioned on-site collaborative treatment system for cardiac arrest, the drone is also used to play the operation information of the treatment equipment for treatment through an external speaker and / or a projection device after transporting the treatment equipment to the location of the navigation beacon terminal.

[0016] For the above-mentioned on-site collaborative treatment system for cardiac arrest, after the drone receives the flight instruction of the dispatching system, it performs the following steps:

[0017] Step 1: The drone enters the emergency response mode and receives the floor where the navigation beacon terminal is located and the planar position of the navigation beacon terminal on that floor sent by the control system.

[0018] Step 2: The drone makes a forward judgment based on its own position and the position of the navigation beacon terminal, calculates multiple flight paths, selects one of the flight paths, and enters Step 3;

[0019] Step 3: Determine whether there is a passage ahead. If so, enter Step 4; if not, mark the current flight path as unavailable, and then enter Step 2;

[0020] Step 4: Fly along the current flight path. If an obstacle is encountered during the flight, enter Step 2;

[0021] Step 5: After the flight is completed, determine whether the navigation beacon terminal location is reached. If so, start to drop the treatment equipment; if not, enter Step 2.

[0022] For the above-mentioned on-site collaborative treatment system for cardiac arrest, when selecting a flight path to enter Step 3 in Step 2, the flight path with the longest vertical passage is preferably selected.

[0023] For the above-mentioned on-site collaborative treatment system for cardiac arrest, the dispatching system has a command large screen, and the command large screen is used to display the execution process of the treatment task.

[0024] The present invention has the following advantages compared with the prior art:

[0025] The technical effects of the solution of the present invention can be analyzed from the following aspects:

[0026] 1. Improve the treatment efficiency: Through the resource information and knowledge information stored in the database, the dispatching system can quickly match the most suitable treatment resources and plans.

[0027] The use of drones has greatly shortened the transportation time of treatment equipment.

[0028] 2. Enhance the collaborative treatment ability: The introduction of the collaborative client enables on-site treatment personnel to receive task updates and feedback on treatment progress in real time, enhancing the collaborative ability between the on-site and the dispatching center.

[0029] The navigation beacon terminal not only provides the location information of the first aid event, but also can play treatment operation information to guide on-site personnel for preliminary treatment.

[0030] 3. Improve the treatment accuracy: The use of the three-dimensional navigation map improves the accuracy of drone navigation, ensuring that the treatment equipment can be accurately delivered to the destination. The accurate position information of the navigation beacon terminal helps the drone to quickly locate and reduce errors.

[0031] 4. Optimize resource allocation: The resource information stored in the database can help the dispatching system to perform intelligent resource allocation, ensuring the rational use and efficient dispatching of resources.

[0032] 5. Enhance information sharing and feedback: The information exchange mechanism between the collaborative client and the dispatching system enables the implementation status of the treatment task to be fed back in real time, facilitating the adjustment of treatment strategies.

[0033] 6. Support remote treatment guidance: The voice and video playback functions of the navigation beacon terminal can provide preliminary treatment guidance before professional medical personnel arrive, increasing the possibility of treatment success.

[0034] Generally speaking, the solution of the present invention significantly improves the treatment efficiency, accuracy and safety at the scene of cardiac arrest, enhances the collaborative treatment ability, and optimizes resource allocation through the integration of various technical means, and has broad application prospects and important social value.

[0035] Next, through the drawings and embodiments, the technical solution of the present invention will be further described in detail. Brief Description of the Drawings

[0036] Figure 1 is the system principle block diagram of the present invention.

[0037] Figure 2 is the schematic diagram of the system usage process of the present invention.

[0038] Figure 3 is the schematic diagram of the navigation process of the drone. Detailed implementation mode

[0039] As Figure 1 shown, a on-site collaborative treatment system for cardiac arrest includes a database, a dispatching system, a collaborative client, a navigation beacon terminal, and a drone.

[0040] In this embodiment, the database is used to store resource information, knowledge information, and three-dimensional navigation maps for treatment; the database includes a resource library, a knowledge library, and a map library;

[0041] The resource library is a collection of resources within the system, including security resources, volunteer resources, medical resources, and drone resources in the region, etc., and can be continuously updated and improved according to the maintenance of the system;

[0042] The knowledge library is a collection of knowledge that can be used to guide non-professional personnel on-site, including patient diagnosis, treatment guidance, AED use, and AI-based human-machine voice interaction, etc.;

[0043] The map library stores the three-dimensional navigation map of the region, which is established through the initialization of the system and can also be updated according to needs later. The database provides knowledge support for the intelligent assistance and collaborative dispatching of the system.

[0044] In this embodiment, the dispatching system is used to command and control the drone and also to send treatment tasks to the collaborative client; the dispatching system has a command large screen, and the command large screen is used to display the execution process of the treatment task.

[0045] The main module of the dispatching system is the Taskflow (task dispatching) module. Through the information collected by the on-site navigation beacon terminal and the drone, as well as the information of the personnel participating in the emergency linkage using the collaborative client, it analyzes the development trend of the task and provides dispatching and command. The whole process of the event is displayed on the Display (command large screen).

[0046] In this embodiment, the collaborative client is used to receive the treatment tasks sent by the dispatching system and to send information on the analysis of the development trend of the task to the dispatching system;

[0047] The collaborative client is installed on the mobile phones of volunteers, medical staff, and security personnel. When receiving a task, the Task (task list) shows the real-time development of the current event, including the basic situation of the patient and the treatment content carried out, etc., to facilitate understanding the on-site situation. The ToDo (to-do reminder) shows the currently assigned tasks, including the planned arrival route, precautions, etc.

[0048] The navigation beacon terminal is used to send the location information of the occurrence of the first aid event to the dispatching system, and when a first aid event occurs, it plays the treatment operation information in the form of voice and / or video;

[0049] The navigation beacon terminal is a terminal device placed on site. It can be placed in a special equipment cabinet or at a service desk. Its main modules include Locate (event location) and AI Assistant (first aid assistance). The event location module provides target point location for drones, volunteers and medical staff through high-precision positioning. The first aid assistance provides intelligent assistance functions for the first stage of first aid through the external speakers and screen on the navigation beacon terminal.

[0050] In this embodiment, the drone is used to transport the rescue equipment to the navigation beacon terminal according to the flight instructions of the dispatch system. The drone is also used to play the operation information of the rescue equipment for rescue through an external speaker and / or a projection device after the rescue equipment is transported to the navigation beacon terminal.

[0051] During actual implementation, the drone is on standby in a specific area. After entering the emergency linkage mode, it quickly plans a route through the AutoNav (automatic navigation) module and rushes to the location of the incident. After arriving, the AI ​​Ass ist (first aid assistance) module provides intelligent assistance functions for the second stage of first aid through the external speakers and projection devices on the drone.

[0052] In this embodiment, after the drone receives the flight instruction from the dispatch system, it uses the built-in three-dimensional navigation map or the three-dimensional navigation map in the database to transport the rescue equipment to the location of the navigation beacon terminal by automatic navigation.

[0053] like Figure 3 As shown, it should be noted that after receiving the flight instruction from the dispatching system, the UAV performs the following steps:

[0054] Step 1: The drone enters the emergency response mode and receives the floor of the navigation beacon terminal and the plane position of the navigation beacon terminal on the floor sent by the control system;

[0055] Step 2: The drone makes a forward judgment based on its own position and the location of the navigation beacon terminal, calculates multiple flight paths, selects one of the flight paths, and proceeds to step 3;

[0056] Step 3: Determine whether there is a channel ahead. If yes, proceed to step 4. If no, mark the current flight path as unavailable and proceed to step 2.

[0057] Step 4: Fly along the current flight path. If an obstacle is encountered during the flight, proceed to step 2.

[0058] Step 5: After the flight is completed, determine whether the navigation beacon terminal has been reached. If so, start deploying rescue equipment. If not, proceed to step 2.

[0059] It should be noted that when selecting a flight path to enter step 3 in step 2, the flight path with the longest vertical channel is preferably selected.

[0060] In another embodiment of the present invention, each flight path planned in step 2 is a local section of the total flight path. When step 4 completes the flight of the local section along the current flight path, it enters step 5, and then returns to step 2 to plan the local section of the next flight path.

[0061] The reason for such operation is that in the actual scene, the patient (carrying the navigation beacon terminal) may be carried, so it is necessary to correct the navigation flight path of the drone in real time in order to fly to the patient (carrying the navigation beacon terminal) faster and more accurately.

[0062] As Figure 2 shown below, taking the first aid event of a patient with sudden cardiac arrest as an example, the execution process of the system of the present invention is described as follows:

[0063] 1. After the system is started, it is in the standby state;

[0064] 2. When sudden cardiac arrest occurs, after the masses discover the patient, they can obtain the navigation beacon terminal nearby through the equipment cabinet or service desk;

[0065] 3. Press the distress button on the beacon terminal, and the system enters the emergency linkage mode;

[0066] 4. The navigation beacon terminal automatically triggers an emergency event in the collaborative treatment system through the network, publishes the real-time location of the event, and calls nearby volunteers, hospital relevant persons in charge, and security personnel;

[0067] 5. Nearby volunteers, hospitals, and security personnel can choose to accept the task and join the emergency linkage after receiving the event;

[0068] A) Rush to the scene according to the best route given by the system;

[0069] B) The security personnel maintain the on-site order according to the pre-plan;

[0070] 6. The drones located in the building are automatically started, plan the navigation path according to the navigation beacon terminal positioning, and set off to the scene;

[0071] A) Play a warning sound on the way to prompt the masses to avoid;

[0072] 7. The navigation beacon terminal guides the holder to rush to the patient's side and place it correctly through the external speaker, and plays the evacuation prompt at intervals to persuade the surrounding onlookers to leave;

[0073] A) After reaching the patient and being placed next to him, the beacon will provide preliminary diagnosis of the patient through external speakers and on-screen guidance;

[0074] B) Before the drone arrives, the beacon performs artificial cardiopulmonary resuscitation on the patient through external speakers and on-screen guidance;

[0075] 8. The drone arrives at the scene, opens the equipment compartment, and prompts the on-site emergency rescuer to take out the AED device;

[0076] 9. Before the follow-up professionals arrive at the scene, the drone guides the defibrillation operation on the patient through the onboard audio and projection images of the projection device;

[0077] 10. If the volunteers arrive at the scene before the medical staff, they will take over the treatment of the patient after arriving;

[0078] 11. Medical staff take over the treatment of patients after arriving at the scene;

[0079] 12. The system's coordination mechanism ends and enters standby mode until a new event occurs.

[0080] The present invention establishes a collaborative rescue mechanism for cardiac arrest patients, and divides the rescue of patients into three stages, namely: manual rescue, AED rescue, and professional rescue. The present invention shortens the switching time of the three stages through collaborative scheduling, drone navigation technology and other means, and guides on-site personnel to perform basic diagnosis and treatment of patients through intelligent assistance in the first two stages, thereby buying time for professional treatment. The present invention makes up for the problem of the lack of on-site professionals, allowing patients to receive treatment more promptly, thereby greatly improving the survival rate of patients with cardiac arrest.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
