Description

Technical Field

[0001] The present invention relates to the technical field of first aid for the wounded, and particularly to a unified dispatching decision-making method and system for pre-hospital first aid. Background Art

[0002] With the rapid development of China's social economy, the incidence rate of patients with severe trauma remains high, and sudden mass casualty incidents occur from time to time. At present, the number of deaths due to trauma in China reaches as high as 700,000 - 800,000 every year, which is the fifth leading cause of death in the overall population. Among people under 45 years old, trauma is the leading cause of death. Early and effective treatment of trauma, especially severe trauma, is the key. Time is life, and efficient dispatching of the pre-hospital first aid center is one of the keys to the early and effective treatment of patients with severe trauma.

[0003] Currently, the existing 120 dispatching center uniformly dispatches 120 ambulances to send patients to various hospitals. There is no effective real-time information exchange between the existing 120 dispatching center and each hospital, and it is impossible to know the treatment level of each hospital for each type of trauma and the current emergency acceptance capacity of each hospital within the dispatching area in the first time. As a result, it is impossible to make a more optimized dispatching. Moreover, for trauma patients, there is no effective plan on how to handle severe trauma and non-severe trauma, and how to handle different numbers of severe trauma and non-severe trauma patients. The existing 120 dispatching center fails to achieve efficient and effective dispatching. Summary of the Invention

[0004] In view of the problems and deficiencies existing in the prior art, the present invention provides a unified dispatching decision-making method and system for pre-hospital first aid.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention provides a unified dispatching decision-making method for pre-hospital first aid, which is characterized by including:

[0007] S1. After the unified dispatching center for pre-hospital first aid confirms that the alarm caller is at the scene, it obtains and analyzes the accident scene information to obtain the accident location, type of trauma, and the number of trauma patients including severe and non-severe cases;

[0008] S2. The unified dispatching center analyzes the number of trauma patients, determines whether the number of trauma patients is one or multiple. If it is one, go to S3; if it is multiple, go to S6;

[0009] S3. The unified dispatching center determines the nature of the trauma of this person. If it is severe trauma, go to S4; if it is non-severe trauma, go to S5;

[0010] S4. The unified dispatching center selects the hospital with the shortest currently estimated arrival time from the hospitals whose trauma type treatment scores match the trauma type of this person and reach the preset value as the target hospital, and notifies the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which they are to be sent.

[0011] S5. The unified dispatching center selects the hospital with the shortest currently estimated arrival time as the target hospital and notifies the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which they are to be sent.

[0012] S6. The unified dispatching center judges the number of severely injured people. If it is one person, go to S4; if it is multiple people, go to S7. Then judge the number of non-severely injured people. If it is one person, go to S5; if it is multiple people, go to S8.

[0013] S7. The unified dispatching center selects the hospitals whose trauma type treatment scores match the trauma type of multiple people and reach the preset value, then sorts the selected hospitals in ascending order of the currently estimated arrival time at the hospital, and selects the target hospital in order according to the current emergency acceptance capacity of these hospitals for this trauma type and notifies the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which each vehicle is to be sent.

[0014] S8. The unified dispatching center sorts the hospitals in ascending order of the currently estimated arrival time at the hospital, and selects the target hospital in order according to the current emergency acceptance capacity of these hospitals for this trauma type and notifies the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which each vehicle is to be sent.

[0015] The present invention also provides a pre-hospital emergency unified dispatching decision-making system, which is characterized by including:

[0016] The unified dispatching center for pre-hospital emergency is used to confirm the information of the accident scene after the alarm caller is at the scene and analyze it to obtain the accident location, trauma type, and the number of severely and non-severely injured people.

[0017] The unified dispatching center is used to analyze the number of injured people, judge whether the number of injured people is one or multiple. When it is one person, judge the nature of the trauma of this person. When it is a severe trauma, select the hospital with the shortest currently estimated arrival time from the hospitals whose trauma type treatment scores match the trauma type of this person and reach the preset value as the target hospital and notify the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which they are to be sent. When it is a non-severe trauma, select the hospital with the shortest currently estimated arrival time as the target hospital and notify the corresponding hospital emergency center. The dispatching can send out first-aid vehicles and notify the hospitals to which they are to be sent.

[0018] When there are multiple people, determine the number of people with severe trauma. When there is one person, select the hospital with the shortest currently estimated arrival time from the hospitals with a trauma treatment score reaching the preset value that matches the trauma type of this person as the target hospital and notify the emergency center of the corresponding hospital. The dispatcher can dispatch an ambulance and notify the hospital to which it is to be sent. When there are multiple people, select the hospitals with a trauma treatment score reaching the preset value that matches the trauma type of the multiple people, and then sort the selected hospitals in ascending order of the currently estimated arrival time. Select the target hospital in order according to the current emergency acceptance capacity of these hospitals for this trauma type and notify the emergency center of the corresponding hospital. The dispatcher can dispatch an ambulance and notify the hospital to which each vehicle is to be sent;

[0019] Determine the number of people with non-severe trauma. When there is one person, select the hospital with the shortest currently estimated arrival time as the target hospital and notify the emergency center of the corresponding hospital. The dispatcher can dispatch an ambulance and notify the hospital to which it is to be sent.

[0022] Figure 1 It is a flowchart of the pre-hospital emergency unified dispatching decision-making method of a preferred embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0023] 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 in conjunction with the 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.

[0024] 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.

[0025] As Figure 1 shown, this embodiment provides a unified dispatching decision-making method for pre-hospital emergency care, which includes the following steps:

[0026] Step 101: The unified dispatching center for pre-hospital emergency care confirms that the alarm caller is at the scene and then obtains the accident scene information, analyzes the accident scene information, and obtains the accident location, type of trauma, and number of trauma victims. The number of trauma victims includes the number of severely injured and the number of non-severely injured.

[0027] This embodiment is applicable to the situation where the alarm caller making the call is at the scene. The alarm caller at the scene can relatively accurately describe the accident scene information, obtain relatively accurate accident scene information, and thus obtain relatively accurate accident location, type of trauma, and number of trauma victims. The types of trauma include burns, gunshot wounds, knife wounds, explosion injuries, etc.

[0028] In step 101, the unified dispatching center receives the emergency call from the alarm caller, confirms that the alarm caller is at the scene and obtains the accident scene information, locates the current position of the emergency call as the accident location, and then analyzes the accident scene information to obtain the type of trauma and the number of trauma victims.

[0029] In step 101, when the unified dispatching center analyzes the accident scene information and the accident scene information gives a definite type of trauma and / or number of trauma victims, it directly gives the type of trauma and / or number of trauma victims; when the accident scene information does not give a definite type of trauma and / or number of trauma victims, it requests a video call with the alarm caller to obtain the accident scene video, and uses the large language model for accident trauma analysis to analyze the accident scene information and the accident scene video to obtain the type of trauma and / or number of trauma victims. Among them, the large language model for accident trauma analysis is trained based on the accident scene information of each historical accident and the corresponding finally confirmed accident location, type of trauma, and number of trauma victims.

[0030] For example: when the accident scene information gives a definite number of trauma victims, it directly gives the number of trauma victims. For the accident scene information that does not give a definite type of trauma, it requests a video call with the alarm caller to obtain the accident scene video, and uses the large language model for accident trauma analysis to analyze the accident scene information and the accident scene video to obtain the type of trauma. For example, in the event of a debris flow, the type of trauma is determined according to the types of trauma that usually occur in previous debris flows.

[0031] When the accident scene information gives a definite type of trauma, directly give the type of trauma. For the accident scene information that does not give a definite number of trauma victims, request a video call with the caller to obtain the accident scene video, and use the large language model for accident trauma analysis to analyze the accident scene information and the accident scene video to obtain the number of trauma victims.

[0032] In this embodiment, it is determined that the types of trauma at the same accident scene are the same. If there is more than one type of trauma described in the accident scene information, the large language model for accident trauma analysis will analyze and give a main one as the type of trauma.

[0033] Step 102: The unified dispatching center analyzes the number of trauma victims, determines whether the number of trauma victims is one or more than one. If it is one, go to Step 103; if it is more than one, go to Step 106.

[0034] Step 103: The unified dispatching center determines the nature of the trauma of this person. If it is a serious trauma, go to Step 104; if it is a non-serious trauma, go to Step 105.

[0035] Step 104: The unified dispatching center selects the hospital with the shortest currently estimated arrival time from the hospitals whose trauma type treatment scores for the trauma type matching that of this person reach the preset score value as the target hospital and notifies the corresponding hospital emergency center, dispatching the currently available ambulances and the number of ambulances dispatched and the number of pre-hospital emergency personnel per vehicle consistent with the number of serious trauma victims, that is, dispatching 1 ambulance, and notifying to send to the hospital.

[0036] In this step, for the hospitals whose trauma type treatment scores for the trauma type matching that of this person reach the preset score value, it indicates that the hospital can treat the serious trauma of the trauma type of this person. For serious trauma, not every hospital has the ability to handle it, so it is necessary to select the hospitals that can handle the serious trauma of the trauma type of this person from each hospital.

[0037] Step 105: The unified dispatching center selects the hospital with the shortest currently estimated arrival time as the target hospital and notifies the corresponding hospital emergency center, dispatching the currently available ambulances and the number of ambulances dispatched and the number of pre-hospital emergency personnel per vehicle consistent with the number of non-serious trauma victims, that is, dispatching 1 ambulance, and notifying to send to the hospital.

[0038] In this step, for non-serious trauma, it is default that every hospital has the ability to handle it, so only the hospital with the shortest estimated time is needed to be selected from each hospital.

[0039] Step 106: The unified dispatching center determines the number of serious trauma victims. If it is one, go to Step 104; if it is more than one, go to Step 107. Determine the number of non-serious trauma victims. If it is one, go to Step 105; if it is more than one, go to Step 108.

[0040] Step 107: The unified dispatching center selects hospitals whose trauma type treatment scores matching the trauma types of multiple people reach the preset score value, then sorts the selected hospitals in ascending order according to the current shortest expected arrival time at the hospital, selects target hospitals in order according to the current emergency reception capacity of these hospitals for this trauma type, and notifies the corresponding hospital emergency centers. Dispatch the ambulances that can be dispatched currently and dispatch the number of ambulances and the number of pre-hospital emergency personnel per vehicle consistent with the number of severe trauma patients, and notify the hospital that each vehicle will be sent to.

[0041] If the selected hospitals are sorted in ascending order according to the current shortest expected arrival time at the hospital, which are Hospital A, Hospital B, Hospital C, Hospital D... in sequence. Among them, for this trauma type, the current emergency reception capacity of Hospital A is 3 wounded, the current emergency reception capacity of Hospital B is 2 wounded, and the current emergency reception capacity of Hospital C is 2 wounded. Now there are 6 severely wounded people to be allocated. Then select target hospitals in order according to the current emergency reception capacity of the selected hospitals for this trauma type. Select Hospital A and send 3 wounded of this trauma type to it, select Hospital B and send 2 wounded of this trauma type to it, select Hospital C and send 1 wounded of this trauma type to it, and notify the hospital emergency centers of Hospital A, Hospital B, and Hospital C respectively.

[0042] Step 108: The unified dispatching center sorts the hospitals in ascending order according to the current shortest expected arrival time at the hospital, selects target hospitals in order according to the current emergency reception capacity of these hospitals for this trauma type, and notifies the corresponding hospital emergency centers. Dispatch the ambulances that can be dispatched currently and dispatch n ambulances and the number of pre-hospital emergency personnel per vehicle, and notify the hospital that each vehicle will be sent to, where n = the number of non-severe trauma patients / the preset number of non-severe trauma patients that can be accommodated per vehicle. When n is not a positive integer, n = the integer part of n plus 1.

[0043] In this step, if n is calculated to be 2.3, then n = 3.

[0044] In this step, the unified dispatching center selects target hospitals according to the principle that the current emergency reception capacity of the sorted hospitals for this trauma type is greater than or equal to the preset number of non-severe trauma patients that can be accommodated per vehicle, and notifies the corresponding hospital emergency centers.

[0045] If hospitals are sorted in ascending order of the current shortest estimated time to reach the hospital, they are Hospital A, Hospital B, Hospital C, Hospital D... Among them, for this type of trauma, the current emergency capacity of Hospital A is 4 wounded, the current emergency capacity of Hospital B is 2 wounded, the current emergency capacity of Hospital C is 3 wounded, and the current emergency capacity of Hospital D is 4 wounded. 3 ambulances are dispatched, and each ambulance can carry 3 wounded. Since the current emergency capacity of Hospital B is 2 wounded, which does not meet the principle that the current emergency capacity should be greater than or equal to the preset number of non-serious traumas that can be accommodated per vehicle, Hospital B is not selected. Instead, Hospital A, Hospital C, and Hospital D are selected as the target hospitals.

[0046] Another example: If hospitals are sorted in ascending order of the current shortest estimated time to reach the hospital, they are Hospital A, Hospital B, Hospital C, Hospital D... Among them, for this type of trauma, the current emergency capacity of Hospital A is 4 wounded, the current emergency capacity of Hospital B is 2 wounded, the current emergency capacity of Hospital C is 3 wounded, and the current emergency capacity of Hospital D is 4 wounded. 3 ambulances are dispatched, 2 of which can carry 3 wounded and 1 can carry 2 wounded. Then Hospital A, Hospital B, and Hospital C are selected as the target hospitals.

[0047] Among them, the current shortest estimated time to reach the hospital = the shortest estimated time from dispatching the vehicle to the accident scene considering the current traffic conditions + the preset first-aid transfer time + the shortest estimated time from departure to the hospital considering the current traffic conditions. The preset first-aid transfer time = the preset time for providing on-site first aid to the wounded and transferring them to the ambulance.

[0048] More optimally, the current shortest estimated time to reach the hospital = the first time + the shortest estimated time from departure to the hospital considering the traffic conditions after the first time. The first time = the shortest estimated time from dispatching the vehicle to the accident scene considering the current traffic conditions + the preset first-aid transfer time. The traffic conditions after the first time are obtained based on the corresponding historical traffic conditions after the first time.

[0049] Among them, the trauma type treatment score = the number of successfully treated severe traumas of this trauma type / the total number of severe traumas of this trauma type. The trauma type treatment score is only calculated when the number of successfully treated severe traumas of this trauma type reaches at least the set number to ensure the sample size and make the calculated trauma type treatment score accurate.

[0050] Moreover, after dispatching the emergency ambulances in step 104 and step 107, the emergency terminals corresponding to each emergency ambulance notify the emergency centers of the hospitals to which they are sent of the time of arrival at the accident scene and request a video call, obtain on-site first aid guidance from the in-hospital first aid medical staff of the corresponding hospital emergency centers, collect the basic information, vital signs, and injury information containing the identity information of the wounded, and transmit them to the corresponding hospital emergency centers. The corresponding hospital emergency centers use the identity information of the wounded to register in advance for them. The emergency terminals notify the corresponding hospital emergency centers of the time of arrival at the hospital to enable them to prepare for receiving the emergency. During the emergency, the corresponding hospital emergency centers input the items to be examined and tested for the wounded and the estimated arrival time, notify the corresponding inspection and testing centers to open the green channel, and also input the items to be operated on for the wounded and the estimated arrival time, and notify the operating center to open the green channel.

[0051] After dispatching the emergency ambulances in step 105 and step 108, the emergency terminals corresponding to each emergency ambulance notify the emergency centers of the hospitals to which they are sent of the time of arrival at the accident scene, and collect the basic information containing the identity information of the wounded and transmit it to the corresponding hospital emergency centers. The corresponding hospital emergency centers use the identity information of the wounded to register in advance for them. The emergency terminals notify the corresponding hospital emergency centers of the time of arrival at the hospital to enable them to prepare for receiving the emergency.

[0052] This embodiment also provides a pre-hospital emergency unified dispatching decision-making system, including: a unified dispatching center for pre-hospital emergency, emergency terminals corresponding to each emergency ambulance, and hospital emergency centers of each hospital, and realizing the unified dispatching of the wounded at the accident scene by using the unified dispatching center, the emergency terminals corresponding to each emergency ambulance, and the hospital emergency centers of each hospital.

[0053] The unified dispatching center is used to confirm that the alarm caller is at the scene and obtain the accident scene information, analyze the accident scene information, and obtain the accident location, type of trauma, and number of trauma victims. The number of trauma victims includes the number of seriously injured and the number of non-seriously injured.

[0054] The unified dispatching center is used to analyze the number of trauma victims, judge whether the number of trauma victims is one or multiple. When it is one, judge the nature of the person's trauma. When it is seriously injured, select the hospital with the shortest current estimated arrival time from the hospitals with a trauma type treatment score reaching a preset score value that matches the person's trauma type as the target hospital and notify the corresponding hospital emergency center, dispatch an available emergency ambulance and notify the hospital to which it is sent. When it is non-seriously injured, select the hospital with the shortest current estimated arrival time as the target hospital and notify the corresponding hospital emergency center, dispatch an available emergency ambulance and notify the hospital to which it is sent.

[0055] When there are multiple people, determine the number of severely injured. When there is one person, select the hospital with the shortest currently estimated time to reach the hospital as the target hospital from the hospitals whose trauma treatment scores for trauma types matching the trauma type of this person reach the preset score value, and notify the corresponding hospital emergency center. The dispatcher can dispatch an ambulance and notify the hospital to which it is sent. When there are multiple people, screen out the hospitals whose trauma treatment scores for trauma types matching the trauma types of the multiple people reach the preset score value, then sort the selected hospitals in ascending order of the currently estimated time to reach the hospital, and select the target hospital in order according to the current emergency acceptance capacity of these hospitals for this trauma type, and notify the corresponding hospital emergency center. The dispatcher can dispatch an ambulance and notify the hospital to which each ambulance is sent.

[0056] Determine the number of non-severely injured. When there is one person, select the hospital with the shortest currently estimated time to reach the hospital as the target hospital and notify the corresponding hospital emergency center. The dispatcher can dispatch an ambulance and notify the hospital to which it is sent. When there are multiple people, sort the hospitals in ascending order of the currently estimated time to reach the hospital, and select the target hospital in order according to the current emergency acceptance capacity of these hospitals for this trauma type, and notify the corresponding hospital emergency center. The dispatcher can dispatch an ambulance and notify the hospital to which each ambulance is sent.

[0057] After dispatching the ambulances corresponding to severe traumas, the emergency terminal corresponding to each ambulance notifies the hospital emergency center corresponding to the hospital to which it is sent of the time to reach the accident scene and requests a video call, obtains on-site first aid guidance from the in-hospital first aid medical staff of the corresponding hospital emergency center, and collects the basic information, vital signs, and injury information containing the identity information of the injured and transmits them to the corresponding hospital emergency center. The corresponding hospital emergency center uses the identity information of the injured to register in advance for him / her. The emergency terminal notifies the corresponding hospital emergency center of the time to reach the hospital to make it ready to receive first aid. During the first aid, the corresponding hospital emergency center inputs the items to be examined and tested for the injured and the estimated arrival time, notifies the corresponding inspection and testing center to open a green channel, and also inputs the items to be operated on for the injured and the estimated arrival time, and notifies the operating center to open a green channel.

[0058] After dispatching the ambulances corresponding to non-severe traumas, the emergency terminal corresponding to each ambulance notifies the hospital emergency center corresponding to the hospital to which it is sent of the time to reach the accident scene, and collects the basic information containing the identity information of the injured and transmits it to the corresponding hospital emergency center. The corresponding hospital emergency center uses the identity information of the injured to register in advance for him / her. The emergency terminal notifies the corresponding hospital emergency center of the time to reach the hospital to make it ready to receive first aid.

[0059] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples. The protection scope of the present invention is defined by the appended claims. Without departing from the principle 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.
