Description

Technical Field

[0001] The present invention relates to the technical field of first aid dispatching for the wounded, and particularly to a first aid dispatching method and system for mass casualty incidents based on dispatching rights. Background Art

[0002] With the rapid development of China's social economy, mass casualty incidents occur from time to time. Efficient dispatching by the pre-hospital emergency center is one of the keys to the early effective treatment of patients in mass casualty incidents. However, the existing pre-hospital emergency centers have the following problems: 1) Regional differences, due to uneven local economic levels, the development levels of pre-hospital emergency centers are uneven; 2) County-level and city-level pre-hospital emergency dispatching centers cannot immediately understand the current emergency acceptance capabilities of each hospital within the dispatching area and cannot make more optimized and efficient dispatching; 3) The existing pre-hospital emergency dispatching centers cannot effectively monitor each emergency vehicle in real time and cannot give effective plans, resulting in the inability of the pre-hospital emergency dispatching centers to achieve more optimized and efficient dispatching. For the above reasons, after the public reports an accident, multiple ambulances often go out at the same time, resulting in frequent empty ambulances for receiving patients, thus wasting a large amount of medical resources. Moreover, when a mass casualty incident occurs, effective dispatching cannot be carried out immediately. Based on this, the present invention designs a first aid dispatching method and system for mass casualty incidents based on dispatching rights. Summary of the Invention

[0003] Aiming at the problems and deficiencies existing in the prior art, the present invention provides a first aid dispatching method and system for mass casualty incidents based on dispatching rights.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a first aid dispatching method for mass casualty incidents based on dispatching rights, which is characterized by including: [[ID=2D]]

[0006] S1. A certain county-level first aid dispatching center receives an alarm about a mass casualty incident, obtains the description information of the accident scene, and analyzes the location of the mass casualty incident, the type of trauma, and the preliminary number of casualties;

[0007] S2. The county-level first aid dispatching center determines whether the preliminary number of casualties reaches a preset condition. If not, it proceeds to S3; if so, it proceeds to S6;

[0008] S3. The county-level first aid dispatching center exercises its dispatching right and dispatches emergency vehicles to the location of the mass casualty incident according to the preliminary number of casualties, the type of trauma, the distances between each hospital in the county and the location of the mass casualty incident, and the current situation of the emergency vehicles that can be dispatched by each hospital in the county;

[0009] S4. The county-level emergency dispatch center obtains the time when each dispatched emergency vehicle arrives at the scene of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital emergency terminal of the first-arrived emergency vehicle at the scene of the mass casualty incident, and adjusts the emergency vehicles going to the scene of the mass casualty incident according to the confirmed number of casualties.

[0010] S5. The county-level emergency dispatch center assigns the hospitals to which each emergency vehicle transporting the wounded is to be sent.

[0011] S6. The county-level emergency dispatch center hands over the dispatching power and synchronizes the information to the city-level emergency dispatch center. The city-level emergency dispatch center dispatches emergency vehicles to the scene of the mass casualty incident according to the preliminary number of casualties, types of trauma, the distance between each hospital in the county and its neighboring counties and / or neighboring urban areas and the scene of the mass casualty incident, and the current situation of the emergency vehicles that can be dispatched by each hospital in the county and its neighboring counties and / or neighboring urban areas.

[0012] S7. The city-level emergency dispatch center obtains the time when each dispatched emergency vehicle arrives at the scene of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital emergency terminal of the first-arrived emergency vehicle at the scene of the mass casualty incident, and adjusts the emergency vehicles going to the scene of the mass casualty incident according to the confirmed number of casualties.

[0013] S8. The city-level emergency dispatch center assigns the hospitals to which each emergency vehicle transporting the wounded is to be sent.

[0014] The present invention also provides a first-aid dispatching system for mass casualty incidents based on dispatching power, which is characterized in that it includes each county-level emergency dispatch center and the upper-level city-level emergency dispatch center.

[0015] A certain county-level emergency dispatch center is used to receive the alarm call of the mass casualty incident, obtain the accident scene description information and analyze the location of the mass casualty incident, type of trauma and preliminary number of casualties.

[0016] The county-level emergency dispatch center is used to judge whether the preliminary number of casualties reaches the preset condition. If not, it exercises the dispatching power, dispatches emergency vehicles to the scene of the mass casualty incident according to the preliminary number of casualties, type of trauma, the distance between each hospital in the county and the scene of the mass casualty incident, and the current situation of the emergency vehicles that can be dispatched by each hospital in the county, obtains the time when each dispatched emergency vehicle arrives at the scene of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital emergency terminal of the first-arrived emergency vehicle at the scene of the mass casualty incident, increases or decreases or does not increase or decrease the emergency vehicles going to the scene of the mass casualty incident according to the confirmed number of casualties, and assigns the hospitals to which each emergency vehicle transporting the wounded is to be sent.

[0017] If so, the county-level first aid dispatch center shall hand over the dispatch power and synchronize the information to the city-level first aid dispatch center. The city-level first aid dispatch center shall dispatch emergency vehicles to the location of the mass casualty incident based on the preliminary number of casualties, types of trauma, the county where the incident occurred and its neighboring counties and / or neighboring urban areas, the distance between each hospital in the above areas and the location of the mass casualty incident, and the current availability of emergency vehicles that can be dispatched from each hospital in the county where the incident occurred and its neighboring counties and / or neighboring urban areas. Obtain the time when each dispatched emergency vehicle arrives at the location of the mass casualty incident, receive the confirmed number of casualties sent by the pre-hospital emergency terminal of the first-arriving emergency vehicle at the location of the mass casualty incident, increase, decrease or not change the number of emergency vehicles dispatched to the location of the mass casualty incident according to the confirmed number of casualties, and allocate the hospitals to which each emergency vehicle transporting the wounded will go.

[0018] The positive and progressive effects of the present invention are as follows:

[0019] The present invention establishes a county-level first aid dispatch center for each county. The county-level first aid dispatch center conducts real-time dynamic monitoring of each emergency vehicle within the county. A city-level first aid dispatch center is established for each city. The city-level first aid dispatch center exchanges information with each county-level first aid dispatch center and conducts real-time dynamic monitoring of each emergency vehicle within the city. When the preliminary number of casualties does not reach the preset condition, the county-level first aid dispatch center exercises the dispatch power by itself. When the preliminary number of casualties reaches the preset condition, the county-level first aid dispatch center needs to transfer the dispatch power to the city-level first aid dispatch center, and the city-level first aid dispatch center exercises the dispatch power, so as to be able to give an effective plan and achieve more optimized and efficient dispatch.

[0020] The county-level and city-level pre-hospital first aid dispatch centers of the present invention can understand the current emergency acceptance capabilities of each hospital within the dispatch area in a timely manner, so as to be able to make more optimized and efficient dispatch. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a flowchart of the first aid dispatch method for mass casualty incidents based on dispatch power according to a preferred embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] For ease of description, only the parts related to the present invention are shown in the drawings. The first, second, etc. involved in the present invention are only for conveniently describing the technical solution of the present invention, and do not have a specific limiting effect. They are all general references and do not constitute a limiting effect on the technical solution of the present invention. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] As Figure 1 shown, this embodiment provides a first-aid dispatch method for mass casualty incidents based on dispatch rights, including:

[0025] Step 101: A certain county-level first-aid dispatch center receives an alarm call for a mass casualty incident, obtains the accident scene description information, and analyzes the location of the mass casualty incident, the type of trauma, and the preliminary number of casualties.

[0026] In this step, the county-level first-aid dispatch center analyzes the accident scene description information of the mass casualty incident to analyze the location of the mass casualty incident, the type of trauma, and the preliminary number of casualties. The location of the mass casualty incident can be provided by the person making the alarm call or located on the electronic map according to the location information described by the person making the alarm call. The type of trauma can be provided by the person making the alarm call or analyzed by big data according to the trauma injury information described by the person making the alarm call. The preliminary number of casualties needs to be provided by the person making the alarm call with a preliminary approximate number of casualties for the subsequent analysis of the number of first-aid vehicles that need to be dispatched initially.

[0027] Step 102: The county-level first-aid dispatch center determines whether the preliminary number of casualties reaches a preset condition. If not, it proceeds to step 103; if so, it proceeds to step 106.

[0028] A general accident refers to an accident that causes less than 3 deaths or less than 10 serious injuries. An accident that causes 3 or more deaths or 10 or more serious injuries is a non-general accident. Then, in this step, the preset condition can be set as the number of deaths reaching 3 or more or the number of serious injuries reaching 10 or more. If the county-level first-aid dispatch center determines that the preliminary number of casualties does not reach this preset condition, the county-level first-aid dispatch center can exercise its own dispatch rights. If the county-level first-aid dispatch center determines that the preliminary number of casualties reaches this preset condition, the county-level first-aid dispatch center needs to hand over the dispatch rights to the upper-level city-level first-aid dispatch center and synchronize the currently obtained information to the city-level first-aid dispatch center. In this embodiment, it is defaulted that the number of first-aid vehicles in all hospitals in the county can meet the dispatching requirements for general accidents.

[0029] Step 103: The county-level first-aid dispatch center exercises its dispatch rights and dispatches first-aid vehicles to the location of the mass casualty incident according to the preliminary number of casualties, the type of trauma, the distances between the hospitals in the county and the location of the mass casualty incident, and the current available first-aid vehicles in the hospitals in the county.

[0030] The specific implementation method is as follows: The county-level emergency dispatch center obtains the preliminary number of ambulances to be dispatched based on the preliminary number of casualties and the type of trauma, sorts the current shortest travel times from the hospitals in the county to the location of the mass casualty incident from the shortest to the longest, obtains the current number of ambulances that can be dispatched from each hospital after sorting, and selects the ambulances that can be dispatched for the preliminary number of ambulances to the location of the mass casualty incident in order according to the number of ambulances that can be dispatched from each hospital after sorting.

[0031] Among them, obtaining the preliminary number of ambulances to be dispatched based on the preliminary number of casualties and the type of trauma is specifically as follows:

[0032] Input the preliminary number of casualties and the type of trauma into the large language model for accident trauma analysis to obtain the preliminary number of ambulances to be dispatched. The large language model for accident trauma analysis is trained based on the number of casualties and the type of trauma in each historical accident and the corresponding number of ambulances to be dispatched.

[0033] The county-level emergency dispatch center can uniformly dispatch the ambulance resources of all hospitals in the county and real-time know the current locations of the ambulances in all hospitals in the county. The county-level emergency dispatch center can dynamically monitor each ambulance with a real-time number. Red represents the maintenance status, yellow represents the waiting status and can be dispatched, and green represents the status of being on a medical treatment mission.

[0034] Further consider the magnitude relationship between the preliminary number of ambulances to be dispatched and the current number of ambulances that can be dispatched, and perform different operation steps according to different magnitude relationships. The county-level emergency dispatch center analyzes the relationship between the preliminary number of ambulances to be dispatched and the current number of ambulances that can be dispatched. When the current number of ambulances that can be dispatched ≥ the preliminary number of ambulances to be dispatched, it indicates that the number of ambulances that can be dispatched currently is sufficient. Select the ambulances that can be dispatched for the preliminary number of ambulances to the location of the mass casualty incident in order according to the number of ambulances that can be dispatched from each hospital after sorting.

[0035] When the current number of ambulances that can be dispatched < the preliminary number of ambulances to be dispatched, it indicates that the number of ambulances that can be dispatched currently is insufficient. Obtain the current locations of each ambulance on the way back to the hospital in the county and information on whether there are wounded on board. Give priority to considering the number of ambulances without wounded on board as the first number. If the first number ≥ the preliminary number of ambulances to be dispatched - the current number of ambulances that can be dispatched, then sort the current shortest travel times from the ambulances without wounded on board to the location of the mass casualty incident from the shortest to the longest, and select the number of ambulances without wounded on board equal to the difference between the preliminary number of ambulances to be dispatched and the current number of ambulances that can be dispatched to the location of the mass casualty incident in order.

[0036] If the first quantity < the initial dispatched vehicle number - the current available ambulances for dispatch, then all ambulances without injured patients go to the mass casualty incident site. Then, considering the ambulances with injured patients, sort the current shortest travel times of the ambulances with injured patients from the hospital back to the mass casualty incident site in ascending order, and select the ambulances in order until the number of ambulances that meet the initial dispatched vehicle number is reached. At this time, the number of ambulances with injured patients to be dispatched = the initial dispatched vehicle number - the current available ambulances for dispatch - the first quantity.

[0037] Step 104: The county-level emergency dispatch center obtains the time when each dispatched ambulance arrives at the mass casualty incident site, receives the confirmed number of casualties sent by the pre-hospital emergency terminal of the ambulance that arrives at the mass casualty incident site first, and increases, decreases, or does not change the number of ambulances going to the mass casualty incident site according to the confirmed number of casualties.

[0038] In this step, the emergency personnel on the ambulance that arrives at the mass casualty incident site first need to confirm the number of casualties, including the number of deaths and the number of injured. The injured include seriously injured and non-seriously injured. After the emergency personnel confirm the number of casualties, they transmit the confirmed number of casualties to the county-level emergency dispatch center through the corresponding pre-hospital emergency terminal.

[0039] In this step, increasing, decreasing, or not changing the number of ambulances going to the mass casualty incident site according to the confirmed number of casualties is specifically as follows:

[0040] The county-level emergency dispatch center analyzes whether the confirmed number of casualties reaches the preset condition. When the confirmed number of casualties does not reach the preset condition, the accurate dispatched vehicle number is obtained according to the confirmed number of casualties, and it is specifically divided into: 1) If the accurate dispatched vehicle number is greater than the initial dispatched vehicle number, obtain the current available ambulances for dispatch of each hospital after sorting, and select the ambulances that can be dispatched to the mass casualty incident site in order according to the current available ambulances for dispatch of each hospital after sorting, and the number of ambulances = the accurate dispatched vehicle number - the initial dispatched vehicle number; 2) If the accurate dispatched vehicle number is equal to the initial dispatched vehicle number, there is no operation to increase or decrease the dispatched vehicles; 3) If the accurate dispatched vehicle number is less than the initial dispatched vehicle number, obtain the current positions of each dispatched ambulance on the way, sort them in descending order according to the current shortest travel times between each current position and the mass casualty incident site, and send a return instruction to the dispatched ambulances on the way with the number equal to the difference between the initial dispatched vehicle number and the accurate dispatched vehicle number selected in order.

[0041] When it is confirmed that the number of casualties reaches the preset condition, the county-level emergency dispatch center transfers the dispatching power and synchronizes the information to the municipal-level emergency dispatch center. The municipal-level emergency dispatch center sorts the current available ambulance numbers of each hospital in the affiliated county, neighboring counties, and / or neighboring urban areas from the shortest to the longest according to the shortest time taken for the path between each hospital and the location of the mass casualty incident. Based on the current available ambulance numbers of each hospital after sorting, the ambulances that can be dispatched to the location of the mass casualty incident are selected in order, and the number of ambulances = the accurate number of dispatched vehicles - the preliminary number of dispatched vehicles.

[0042] When it is confirmed that the number of casualties does not reach the preset condition, there are three situations: increasing the number of ambulances, keeping the number of ambulances unchanged, and reducing the number of ambulances. When it is confirmed that the number of casualties reaches the preset condition, there is only the situation of increasing the number of ambulances.

[0043] Furthermore, when the accurate number of dispatched vehicles is greater than the preliminary number of dispatched vehicles, the county-level emergency dispatch center takes the value of the accurate number of dispatched vehicles - the preliminary number of dispatched vehicles as the increased number. Analyze the relationship between the increased number and the current available ambulance numbers. When the current available ambulance numbers ≥ the increased number, based on the current available ambulance numbers of each hospital after sorting, the ambulances with the increased number that can be dispatched are selected in order to the location of the mass casualty incident.

[0044] When the current available ambulance numbers < the increased number, obtain the current positions of each ambulance on the way back to the hospital and information on whether there are wounded patients. Give priority to considering the number of ambulances without wounded patients as the third number. If the third number ≥ the increased number - the current available ambulance numbers, sort the shortest current path times from the ambulances without wounded patients to the location of the mass casualty incident from the shortest to the longest, and select the difference number of ambulances without wounded patients equal to the increased number - the current available ambulance numbers in order to the location of the mass casualty incident.

[0045] If the third number < the increased number - the current available ambulance numbers, all the ambulances without wounded patients go to the location of the mass casualty incident. Then consider the ambulances with wounded patients. Sort the shortest current path times from the ambulances with wounded patients back to the hospital and then to the location of the mass casualty incident from the shortest to the longest, and select the ambulances until the number of ambulances meets the increased number in order to the location of the mass casualty incident.

[0046] Step 105: The county-level emergency dispatch center assigns the hospitals to which each ambulance transporting the wounded will go.

[0047] In this step, receive the information instructions on transporting the wounded to the hospital and the current injury conditions of the wounded sent by the pre-hospital emergency terminals of each ambulance at the location of the mass casualty incident, obtain the current emergency acceptance capabilities of each hospital after sorting, and assign the hospitals to which each ambulance will go in order from the sorted hospitals according to the order of the information instructions, and notify the corresponding hospital emergency centers and pre-hospital emergency terminals.

[0048] Step 106: The county-level first aid dispatching center transfers the dispatching power and synchronizes information to the upper-level city-level first aid dispatching center. The city-level first aid dispatching center dispatches emergency vehicles to the location of the mass casualty incident based on the preliminary number of casualties, types of trauma, the county and adjacent counties and / or adjacent urban areas where the hospitals are located, the distances between the hospitals and the location of the mass casualty incident, and the current availability of emergency vehicles that can be dispatched by the hospitals in the county and adjacent counties and / or adjacent urban areas.

[0049] The specific implementation method is as follows: The city-level first aid dispatching center obtains the preliminary number of emergency vehicles to be dispatched based on the preliminary number of casualties and types of trauma, sorts the hospitals in the county and adjacent counties and / or adjacent urban areas according to the shortest travel time from the location of the mass casualty incident from short to long, obtains the current number of emergency vehicles that can be dispatched by each hospital after sorting, and selects the emergency vehicles that can be dispatched for the preliminary number of emergency vehicles to be dispatched in sequence according to the number of emergency vehicles that can be dispatched by each hospital after sorting and sends them to the location of the mass casualty incident.

[0050] Step 107: The city-level first aid dispatching center obtains the time when each dispatched emergency vehicle arrives at the location of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital emergency terminal of the first-arrived emergency vehicle at the location of the mass casualty incident, and increases, decreases, or does not change the number of emergency vehicles going to the location of the mass casualty incident according to the confirmed number of casualties.

[0051] In this step, increasing, decreasing, or not changing the number of emergency vehicles going to the location of the mass casualty incident according to the confirmed number of casualties is specifically as follows:

[0052] Obtain the accurate number of emergency vehicles to be dispatched based on the confirmed number of casualties. If the accurate number of emergency vehicles to be dispatched is greater than the preliminary number of emergency vehicles to be dispatched, obtain the current number of emergency vehicles that can be dispatched by each hospital after sorting, and select the emergency vehicles that can be dispatched to the location of the mass casualty incident in sequence according to the current number of emergency vehicles that can be dispatched by each hospital after sorting, and the number of emergency vehicles = the accurate number of emergency vehicles to be dispatched - the preliminary number of emergency vehicles to be dispatched; if the accurate number of emergency vehicles to be dispatched is equal to the preliminary number of emergency vehicles to be dispatched, there is no operation to increase or decrease the number of emergency vehicles; if the accurate number of emergency vehicles to be dispatched is less than the preliminary number of emergency vehicles to be dispatched, obtain the current positions of the dispatched emergency vehicles on the way, sort them according to the longest current shortest travel time from the current positions to the location of the mass casualty incident from long to short, and send a return instruction to the dispatched emergency vehicles on the way with the number of vehicles equal to the difference between the preliminary number of emergency vehicles to be dispatched and the accurate number of emergency vehicles to be dispatched selected in sequence.

[0053] Step 108: The city-level first aid dispatching center assigns the hospitals to which each emergency vehicle transporting the wounded will go.

[0054] In this step, receive the information instructions on transporting the wounded to the hospital and the current injury conditions of the wounded sent by the pre-hospital emergency terminals of each emergency vehicle at the location of the mass casualty incident, obtain the current emergency acceptance capacity of each hospital after sorting, and assign the hospitals to which each emergency vehicle will go in sequence from the sorted hospitals according to the order of the information instructions, and notify the corresponding hospital emergency centers and pre-hospital emergency terminals.

[0055] This embodiment also provides a first-aid dispatching system for mass casualty incidents based on dispatching rights, including each county-level first-aid dispatching center and the upper-level city-level first-aid dispatching center.

[0056] A certain county-level first-aid dispatching center is used to receive an alarm call for a mass casualty incident, obtain the description information of the accident site, and analyze the location of the mass casualty incident, the type of trauma, and the preliminary number of casualties.

[0057] The county-level first-aid dispatching center is used to judge whether the preliminary number of casualties reaches a preset condition. If not, it exercises the dispatching right, dispatches ambulances to the location of the mass casualty incident according to the preliminary number of casualties, the type of trauma, the distances between each hospital in the county and the location of the mass casualty incident, and the current available ambulances in each hospital in the county, obtains the arrival time of each dispatched ambulance at the location of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital first-aid terminal of the first-arrived ambulance at the location of the mass casualty incident, increases or decreases or does not increase or decrease the ambulances dispatched to the location of the mass casualty incident according to the confirmed number of casualties, and assigns the hospitals to which each ambulance sending the wounded goes.

[0058] If so, the county-level first-aid dispatching center hands over the dispatching right and synchronizes the information to the city-level first-aid dispatching center. The city-level first-aid dispatching center dispatches ambulances to the location of the mass casualty incident according to the preliminary number of casualties, the type of trauma, the distances between each hospital in the county, neighboring counties and / or neighboring urban areas and the location of the mass casualty incident, and the current available ambulances in each hospital in the county, neighboring counties and / or neighboring urban areas, obtains the arrival time of each dispatched ambulance at the location of the mass casualty incident, receives the confirmed number of casualties sent by the pre-hospital first-aid terminal of the first-arrived ambulance at the location of the mass casualty incident, increases or decreases or does not increase or decrease the ambulances dispatched to the location of the mass casualty incident according to the confirmed number of casualties, and assigns the hospitals to which each ambulance sending the wounded goes.

The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
