Description

Emergency support system

The present invention relates to an emergency support system for supporting lifesaving activities of emergency personnel, and in particular, to improve the efficiency and speed of various lifesaving activities by emergency personnel, to speed up the acquisition of patient data at the hospital side that accepts the patient, and thus to the patient. It relates to an emergency support system that contributes to ensuring the safety of the body and life.

Various systems have been proposed, developed and used for supporting emergency activities by emergency personnel.
For example, Japanese Patent Application Laid-Open No. 2011-103521 discloses a technology related to a rescue support system that supports emergency activities when an elderly person or sick person is in an accident when going out or when symptoms worsen, and it is possible to realize a quick rescue. Sex has been suggested.

Japanese Patent Laid-Open No. 2010-15443 discloses a technique relating to a system for grasping the working status and working status of hospital personnel and notifying an ambulance etc. of information on whether or not an emergency patient can be accepted. There has been suggested the possibility of providing an emergency medical support system that can avoid the so-called whirling in which the time elapses without the hospital being decided easily.

Furthermore, Japanese Patent Application Laid-Open No. 2007-128245 discloses a technique for shortening the time required for transporting a patient by making it possible to accurately specify a transport destination hospital in a short time.

In the emergency support system using each of the above technologies, hospital reception information is simply displayed through the terminal for notification to hospital emergency personnel, and hospital selection / determination is entrusted to the personnel. It could not be said that selecting the optimal hospital to transport the patient could be realized sufficiently.

In addition, the emergency support system using the above-described technology is not sufficient as a means for centrally managing all information related to the current status of the emergency team and the condition of the patient, which is information related to emergency transport. That is, it has been difficult to perform efficient transportation activities by sharing various information related to emergency transportation between the headquarters and the ambulance team or between the ambulance teams.

As a result, it may cause the phenomenon that transportation is concentrated in one hospital, the cause is toxic gas, pathogenic bacteria that can cause pandemic, etc. Even if it is assumed that this is a large amount of information, this important amount of information can be quickly and accurately transmitted to all other emergency services and headquarters, and it cannot be transmitted as danger information. Could result in exposure.

In addition, as an emergency crew member's duty, it is necessary to document the patient's condition at the time of patient accommodation, but there are very few cases where there is room to make a written document when dealing with a patient who requires tertiary or secondary emergency medical care. There is a considerable burden of creating the document. In addition, it is necessary to save the prepared document as data after transporting the patient, but since the same document will be generated again, it is a complicated and time-consuming work that requires a lot of time. And it was a situation that could affect the response to other first aid requests.

On the other hand, the emergency support system using the above-mentioned existing patented technology has not taken any measures, so it cannot be said that drastic improvement in transport efficiency has been realized.

Therefore, it is a system that can manage emergency team information and patient information in a unified manner and determine the most suitable hospital that can be transported. It can improve the efficiency and speed of various lifesaving activities and improve the safety of the patient's body and life. The development of an emergency support system that contributes to securing was desired.

Hereinafter, an emergency support system according to the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is a schematic diagram of an emergency support system, and FIG. 2 is a configuration diagram of the emergency support system. FIG. 3 is an operation flowchart of the patient transport hospital determining means, and FIG. 4 is an operation flowchart of the voice recognition system. FIG. 5 is a flowchart of the voice input process.

As shown in FIG. 1, the emergency support system according to the present invention includes a main server 10, a local government server 20, a terminal computer 30, a local government firefighting headquarter computer 40, a hospital computer 100, and a doctor's mobile phone 160. It is configured to be connected so as to be able to communicate with each other via a network.

The main server 10 is a core device of the emergency support system according to the present invention, accumulates and manages patient data, hospital data, emergency crew data, and emergency team activity time lapse data, and performs various calculation processes. It is a server. The main server 10 can be configured as a single unit, but considering that the main server 10 requires a large number of processes and high performance, distributed processing or the like by a plurality of server computers as in this embodiment. It is desirable to have a configuration that can perform the above. It is also possible to place a server or server group in the user's data center, etc., but data management using so-called cloud computing technology from the viewpoint of safety of data management and simplification of system operation and maintenance A method (an operation method for converting a server into a cloud) may be used.

The main server 10 stores and manages patient data, hospital data, ambulance crew data, and ambulance team activity time lapse data. The patient data is a data group transmitted from the terminal computer 30 to be described later (paragraph [0045]) by the terminal data transmitting means 60, and includes personal information (name, address, date of birth, sex, history) of the patient as attributes. Etc.), the type of injury and illness, the degree of injury and illness, the condition, the treatment content, and the patient data table having the accommodation position.

The hospital data is stored in the local government server 20 installed in each local government and is data related to an emergency designated hospital in the local government that is posted on the Internet emergency medical information site of the local government. It is a data group acquired from. The hospital data is constituted by a hospital data table having, as attributes, the facility name, address, contact telephone number, specialized subject, position information, vacant bed information, availability of the doctor in charge, and the name of the doctor in charge of the emergency designated hospital. Since the hospital data is updated at regular intervals, it is desirable from the viewpoint of using the latest information that the read time of the hospital data by the main server is immediately after the update time of the hospital data.

The ambulance team data is a data group stored in the terminal computer 30 and transmitted to the main server 10 by the terminal data transmission means 60 described later (paragraph [0049]). As attributes, the present location, activity status ( It consists of an ambulance team data table having on-site arrival, patient contact, patient accommodation, patient transport, hospital arrival, hospital waiting, hospital departure, fire department return). The current location of all ambulance crews is acquired from position information data using a GPS sensor. That is, by using the GPS sensor built in the terminal computer 30 or the like, the latitude / longitude information (position information) of the patient rescue point is sent to the main server 10 so that the main server 10 has the current location of the ambulance (in many cases, the rescue location). It is also possible to determine the most appropriate receiving hospital (one or more) by automatically calculating from the transport point), patient symptoms / conditions, hospital acceptance system data, and distance / distance to the candidate hospital. Become.

The ambulance team activity time lapse data is a data group which is accumulated in the terminal computer 30 and transmitted to the main server 10 by the terminal data transmitting means 60 described later (paragraph [0049]). , Time of entry, Time of arrival on site, Time of patient contact, Time of patient's accommodation in ambulance, Time of departure, Time of arrival at hospital, Time of patient's accommodation by hospital, Time of raising emergency hospital, Return It is composed of an ambulance team activity time lapse data table having hours and minutes. The terminal computer 30 automatically distributes this data to the main server 10 by the terminal data transmission means 60, and the main server 10 automatically calculates and processes the current position and activity status of each ambulance, which will be described later (paragraph [0071]. ]) To the local firefighting headquarters computer 40 by the emergency team activity status data transmission means 120, and the local government firefighting headquarters computer 40 uses the rescuer activity status data generation means on the computer of the command center of the local firefighting headquarters. In addition, it is possible to check the activity status of all ambulances that are dispatched and to issue appropriate instructions.

As shown in FIG. 2, the main server 10 includes a patient transfer hospital determination unit 70 and a transfer destination hospital data transmission unit 80.

The patient transport hospital determination means 70 quantifies and integrates data such as the location information of the terminal computer 30, the location information of all emergency designated hospitals in the local government, the specialized subjects of the emergency hospital, the availability of doctors, the bed availability information, etc. Using this, the main server 10 is a means for calculating the optimum delivery destination hospital and determining the delivery destination.

That is, patient data (type of injury / condition / contents of treatment / rescue point / (if known, past disease / current disease name / treatment history / medicine history)), hospital data (main server 10 received and accumulated from terminal computer 30) According to each attribute of the emergency designated hospital address, specialized subjects, information about available beds, availability of doctors in charge, contact telephone number), and ambulance team data (positional data by ambulance team GPS, status of crew members) In addition to processing the score so that it is effective by multiplying the ratio given according to the importance and urgency, and summing up these processed scores, Determine the hospital. The site and type of disease, as well as the evaluation of urgency, can be changed with certain standards, taking into account the evaluation by physicians as well as the evaluation by emergency personnel. For example, even if the ratio of general illnesses to each hospital is the same, only a specific hospital may be set to a high ratio for a specific illness. In addition, the ratio of doctors will be changed depending on the field of expertise. Furthermore, the ratio for each hospital is always changed according to the position information by the GPS of the ambulance team. Thereby, it becomes possible to support the transport of the emergency patient by the ambulance crew.

The patient transport hospital determining means 70 is processed according to the flow shown in FIG. That is, the main server 10 calculates patient data, hospital data, and emergency crew data. If the specialized subject of the hospital matches the patient's injury and illness, the doctor can cope with it, and the result that there is an empty bed is obtained, the nearest hospital is selected from the emergency crew data and the location information of the hospital data. If the shortest hospital is unable to accept the patient due to the availability of a doctor or an empty bed, the hospital with the shortest distance from the rescue site is selected and determined. If none of the hospitals has a patient acceptance system, an alert signal is sent to all emergency designated hospitals in the local government, mobile phones 160 of all duty doctors, and the local firefighting headquarters by alert information transmitting means 110 described later (paragraph [0066]). (So-called escalation is performed).

The current selection criteria for the optimal hospital is that if the patient is moderate to severe, the emergency personnel will judge from the patient's symptoms and be the doctor in charge of the emergency designated hospital that seems to be optimal (distance from the specialized subject / site) Calls are requested for acceptance, and in the case of mild cases, patients often call their hospital to request acceptance. For this reason, there is a problem that the selection of the destination hospital takes time because the selection of the destination hospital largely depends on the experience of the emergency personnel, and in some cases it is not performed smoothly. According to the present invention, it is possible to determine a delivery destination hospital by calculation processing, and it is possible to realize quick and reliable patient transportation by combining functions of an alert information transmission unit 110 described later.

The transfer destination hospital data transmission means 80 is means for transmitting the hospital data determined by the patient transfer hospital determination means 70 to the terminal computer 30. As the data transmission means, it is possible to use a high-speed wireless data line such as an Internet network or a dedicated line. From the viewpoint of preventing information leakage, it is desirable to enhance security by using a technology such as SSL-VPN.

The ambulance team activity status data generation means 90 is means for generating emergency team activity status data from the emergency team data and the ambulance team activity time lapse data. Activity status of all emergency services in the jurisdiction (for example, waiting, rushing to the scene, patient contact, patient accommodation, departure from the hospital, arrival at the hospital, waiting at the hospital, departure from the hospital, returning to the hospital, return, etc.) The present location information is generated, and the generated data is sent from the main server 10 to the local government fire department headquarters computer 40 by the ambulance team activity status data transmission means 120 described later (paragraph [0071]). In the local fire brigade headquarters, the local fire department headquarters computer 40 can list the activities of all ambulance teams. As a result, it is possible to manage the activity status of all members in the jurisdiction, making it easier for the firefighting headquarters to grasp the status of the members, and to give accurate instructions to the members.

The local government server 20 is a server used for storing and providing the hospital data. One or a plurality of local government servers are installed in each local government, and the emergency medical information of each local government (mainly a prefecture unit) belongs to the residents and the local government. This is a server that allows an emergency team to browse through a web browser or the like. The hospital data stored in the server is usually updated on a daily basis. That is, the facility name, specialized subject name, telephone number, (name of doctor in charge, availability of doctors, availability of beds, etc.) of emergency designated hospitals in the local government are periodically edited and updated.

The terminal computer 30 is a computer possessed by emergency personnel, transmits the accumulated patient data, emergency personnel data, and ambulance activity time lapse data to the main server, and data distributed from the main server 10 Is a device used to receive, calculate and output The terminal computer 30 can select an arbitrary one such as a laptop computer or an electronic tablet, but it is necessary to transmit the latitude and longitude information (position information) of the patient rescue point to the emergency crew data transmitted to the main server 10. Therefore, it is desirable to incorporate a GPS sensor. Further, since it is necessary to cope with voice input by the terminal data input means 50 described later, it is desirable that a voice input microphone or the like is provided or can be connected.

The local government firefighting headquarters computer 40 is a computer that is arranged in each local government firefighting headquarters and receives, calculates, and outputs data distributed from the main server 10.
Further, the hospital computer 100 allows the patient data transmitted by the main server 10 or displayed on the Web browser to be viewed on the computer in the emergency medical department of the hospital, and the doctor in charge fills in the findings and electronically signs them. Equipment.

The input process is started by the utterance such as “voice start” of the emergency personnel. The input contents are classified into large items and small items. When uttering a major item name, speak either “lifesaving treatment” or “observation / treatment progress”.

When lifesaving treatments are uttered, the contents of the lifesaving treatments performed are stored as patient data. Here, treatments such as defibrillation (AED), airway securing, vein securing, and drug administration can be input by voice. Further, when the progress of observation / treatment is spoken, a process of saving the patient's condition before and after the treatment as patient data is performed. Here, the patient's consciousness, breathing, pulse, ECG, blood pressure, trend, SpO2, body temperature, body position, etc. can be input by voice. In addition, although the major item name speaks either “lifesaving treatment etc.” or “the progress of observation / treatment” in the present embodiment, it is not limited to these.

For each utterance, the voice recognition software 540 performs a voice data character data conversion process. When inputting a small item, if it is within the same large item, it is possible to move to another small item and perform input processing by speaking the small item name. As described above, patient data can be input accurately and promptly.
