  DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of a travel route setting device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a conveyance support apparatus including an embodiment of a travel route setting apparatus according to the present invention. In the figure, a conveyance support apparatus 1 is an apparatus that supports conveyance of a vehicle occupant to a medical institution. The conveyance support apparatus 1 includes a biological monitor device 2, a host vehicle position detector 3, an ECU (Electronic Control Unit) 4, and a communication device 5.

  The biological monitor device 2 measures the health state (symptoms) of the transporter. The biological monitor device 2 is mounted on the vehicle in advance or used by being connected to the vehicle. The own vehicle position detector 3 detects the current position of the own vehicle using, for example, a GPS receiver. The communication device 5 is a device for making a request for dispatch of an ambulance vehicle to the fire department through communication.

  The ECU 4 includes a CPU, a memory such as a ROM and a RAM, an input / output circuit, and the like. The ECU 4 includes a medical information database 6, a necessary device request unit 7, a joining / transfer determining unit 8, and a route searching unit 9.

  In the medical information database 6, the symptoms of the subject and the optimal treatment content are registered as medical information.

  The necessary equipment requesting unit 7 determines a symptom suitable for the transporter from the measurement data of the biological monitor device 2, searches the medical information database 6 for the initial treatment content effective for the symptom, and performs the medical treatment necessary for the initial treatment. Request the equipment and the postponement time after carrying out the treatment.

  The joining / transfer determining unit 8 determines whether or not the joining of the own vehicle and the emergency vehicle and the transfer of the required transporter to the emergency vehicle are necessary based on the medical equipment necessary for the treatment of the required transporter. Specifically, the merging / transfer determining unit 8 has a medical device necessary for the treatment of the transporter required mounted on an ambulance vehicle, and needs to perform an initial treatment of the transporter using the medical device. Therefore, it is determined that it is necessary to transfer the transporter to the emergency vehicle.

  The route search unit 9 calculates a route (merging route) where the host vehicle and the ambulance vehicle merge when it is determined by the merging / transfer determining unit 8 that the transporter needs to be transferred to the emergency vehicle. . At this time, an ambulance vehicle that can merge with the host vehicle is searched, and an ambulance vehicle that can merge most efficiently is selected. Also, if the need and effectiveness of the initial treatment due to the transfer of the transporter changes due to changes in the transporter's symptom during the transport of the transporter, the merging route between the vehicle and the emergency vehicle Is recalculated.

  FIG. 2 is a flowchart showing details of a processing procedure executed by the ECU 4. In the figure, first, the health condition (symptoms) of the transporter required measured by the biological monitor device 2 is input (procedure S21), and a medical device required for the treatment according to the symptom of the transportee is requested (procedure) S22).

  At this time, data registered in the medical information database 6 is searched based on the measurement data of the biological monitor device 2. Then, the symptom of the recipient is identified from the current biological information and the past history of the recipient, an effective treatment method is calculated, and a medical device necessary for this treatment is requested. If it is difficult to specify symptoms from the medical information database 6, a doctor's instruction may be received through communication with a medical institution.

  For example, if the current biological information of the recipient is heart rate reduction and pulse reduction and the recipient has a history of heart disease, the effective initial treatment is oxygen inhalation, and oxygen inhalation as a medical device Request a vessel.

  Subsequently, it is determined whether transfer to the ambulance is necessary on the basis of the medical device to be used for the currently required initial treatment (step S23). Specifically, it is determined whether or not the initial treatment can be performed with the medical device installed in the own vehicle on which the transported person is currently boarded. Judge that transfer to the vehicle is not required. On the other hand, when the required medical equipment is not in the host vehicle and is mounted on the ambulance vehicle, transfer to the ambulance vehicle is considered.

  In addition, the determination as to whether or not to select transfer to an ambulance vehicle is made as follows. In other words, as shown in FIG. 3, the initial period obtained from the search of the data in the medical information database 6 or the initial period suggested by the medical institution, and the transfer postponement time when such initial process is not performed. The postponed transportation time is compared with the estimated arrival time calculated based on traffic information and the like.

The graph shown in FIG. 3 represents the relationship between the conveyance time and the lifesaving probability when the initial treatment is performed and when the initial treatment is not performed. The solid line P in the figure represents the time when the paper is directly transported to the medical institution without performing the initial treatment, and the broken line Q in the figure joins and transfers to the ambulance vehicle to carry out the initial treatment, and to the medical institution It shows the time when transported. In addition, a solid line P ₀ in the figure represents a recommended transport time limit (transfer postponement time) when the initial treatment is not performed, and a solid line Q ₀ in the figure represents a recommended transport time limit when the initial treatment is performed. ing.

Here, when the arrival time by the direct conveyance is less than the conveyance postponement time P ₀ when the initial treatment is not performed, the direct conveyance is continued. On the other hand, if the arrival time due to direct transportation cannot be less than the transportation delay time P ₀ when the initial treatment is not performed, the initial treatment is performed even if the arrival time at the medical institution is delayed due to merging with an ambulance vehicle it is possible to select a merge-ERROR the emergency vehicle to meet the conveying grace time Q ₀ in the case of. If there is no effect on the arrival time due to the joining / transfer of the ambulance vehicle, the joining / transfer of the ambulance vehicle is selected in order to secure a more reliable treatment system.

  Returning to FIG. 2, when it is determined in step S <b> 23 that the transfer to the ambulance vehicle is not necessary, this flow is ended. As a result, while the initial treatment is executed by the medical device mounted on the host vehicle, the transport to the appropriate medical institution by the host vehicle is continued.

  On the other hand, when it is determined that transfer to the ambulance vehicle is necessary, the merging route between the own vehicle and the ambulance vehicle is calculated based on the current position of the own vehicle detected by the own vehicle position detector 3. (Procedure S24). Subsequently, it is determined whether or not there is a delay in arrival time of the medical period due to transfer to the ambulance vehicle (procedure S25).

Then, the communication device 5 makes a request for the dispatch of an ambulance vehicle (step S27), and this flow is finished. Thereby, the own vehicle joins the ambulance vehicle, the transporter who has boarded the own vehicle is transferred to the ambulance vehicle, and the ambulance is transported to an appropriate medical institution.

  If it is determined in step S25 that the medical period arrival time is delayed due to the transfer to the ambulance vehicle, it is determined whether the initial treatment of the transporter in the ambulance has priority over the delay in the medical period arrival time. (Procedure S28). When it is determined that priority is not given to the initial treatment of the transporter in the emergency vehicle over the delay in the medical period arrival time, this flow is ended. Thereby, the conveyance to the medical period by the own vehicle is continued as described above.

  On the other hand, when it is determined that the initial treatment of the transporter in the emergency vehicle is prioritized over the delay in the medical period arrival time, the merging route between the own vehicle and the emergency vehicle obtained in step S24 is set ( In step S26), the communication device 5 issues a request for dispatch of an ambulance vehicle (step S27), and this flow is terminated. Thereby, as mentioned above, the own vehicle joins the ambulance vehicle, the transporter is transferred to the ambulance vehicle, and the ambulance is transported to the medical institution.

  In the above, the steps S21 and S22 are executed by the necessary device request unit 7. Steps S23, S25, and S28 are executed by the merging / transfer determining unit 8. Steps S24, S26, and S27 are executed by the route search unit 9.
