[0050] Embodiment 1

[0051] The embodiment of the present invention provides an emergency guidance system, which is arranged on a medical ship. A medical ship is a ship with hospital functions for providing humanitarian medical care. Figure 1 FIG. 1 is a schematic diagram of a top view of a medical ship provided in Embodiment 1 of the present invention. Figure 1 As shown, a hospital ship usually includes at least one cabin ( Figure 1 In the figure, a medical ship is drawn with two cabins as an example, and each cabin includes several rooms. The rooms are connected by passages (also called corridors), and passage doors can be set on the passages to separate the space on both sides of the doors.

[0052] The rooms on a medical ship can be divided into at least workstations and medical areas according to their functions. Workstations refer to rooms where medical staff work, such as doctors' offices, nurses' stations, pharmacies, operating rooms, etc.; medical areas refer to rooms where patients are, such as wards, recovery rooms, infusion rooms, etc.

[0053] Figure 2 FIG. 1 is a schematic diagram of the structure of an emergency guidance system provided by Embodiment 1 of the present invention. Figure 2 As shown, the emergency guidance system includes: a pager 101 , an alarm 102 , a central controller 103 , a first indication device 104 and a second indication device 105 .

[0054] At least one pager 101 is provided in a medical area. The pager 101 is usually installed in a place where the patient can easily touch it, so that the patient can initiate a call. Exemplarily, when the button of the pager 101 is pressed, the pager 101 is triggered, indicating that the patient has initiated a call. In one embodiment, in order to prevent accidental touch, a protective shell can be provided outside the pager 101.

[0055] Figure 3 Schematic diagram of a pager provided by Embodiment 1 of the present invention. Figure 3 As shown, the pager 101 may be a blue code emergency pager. Blue code is an important emergency response mechanism used to ensure that medical resources can be quickly mobilized for effective treatment in the event of an emergency medical situation. The pager has a call button (push to call), and when the call button is pressed, the pager initiates a call.

[0056] Each door of each medical area is provided with an alarm 102. Optionally, the alarm 102 may be an audible and visual alarm to remind medical staff through sound and light effects that a call has been initiated by a caller 101 in the corresponding medical area.

[0057] Each passage of the medical ship is provided with a first indicator device 104. The function of the first indicator device 104 is to guide the medical staff in the direction in which they should walk on the passage. In one embodiment, the first indicator device 104 is a directional light (such as a bidirectional directional light) or a light strip. Figure 41 is a schematic diagram of a direction lamp provided in Embodiment 1 of the present invention. When the first indicating device is a direction lamp, the direction is displayed by the direction lamp; when the first indicating device is a light strip, the direction is displayed by the flowing water effect or the chasing light effect of the light strip.

[0058] A second indicator device 105 is provided on both sides of each passage door of the medical ship. The function of the second indicator device 105 is to guide the medical staff whether they need to pass through the passage door. In one embodiment, the second indicator device 105 is an indicator light. Figure 5 Schematic diagram of an indicator light provided in Embodiment 1 of the present invention. When the indicator light is on, it indicates that the medical staff needs to pass through the passage door; when the indicator light is off, it indicates that the medical staff does not need to pass through the passage door.

[0059] Optionally, the first indicator device 104 and the second indicator device 105 may be powered by POE (Power Over Ethernet). The first indicator device 104 and the second indicator device 105 may be fixed in an embedded manner to ensure the beauty of the interior of the cabin.

[0060] The central controller 103 is electrically connected to the pager 101, the alarm 102, the first indicator device 104, and the second indicator device 105, respectively, so as to collect the signal sent by the pager 101 and control the alarm 102, the first indicator device 104, and the second indicator device 105. The central controller 103 can be set in a workstation to facilitate monitoring and system maintenance by medical staff.

[0061] The workflow of the emergency guidance system is as follows: when the target caller (i.e., at least one of all callers 101) is triggered, the central controller 103 can collect the signal sent by the target caller and control all the alarms 102 at the door of the target medical area where the target caller is located to alarm. At the same time, the central controller 103 determines the target path from the workstation to the target medical area, and lights up the first indicator device 104 and / or the second indicator device 105 on the target path to guide the medical staff. In this way, the problem of delaying the rescue time due to the medical staff's unfamiliarity with the cabin layout is avoided, the patient's life safety is guaranteed, and the potential risk of medical disputes is eliminated.

[0062] In one embodiment, the pager 101 has a self-locking device, such as Figure 3 After the medical staff arrives at the target medical area, they can press the reset button to trigger the self-locking device, so that the central controller 103 controls all the alarms 102 at the door of the target medical area to stop the alarm.

[0063] Since the size of a medical ship may be large and the number of medical areas is large, multiple pagers may be triggered at the same time. In a possible implementation, a priority can be set for each pager in advance. When multiple pagers are triggered at the same time, the pager with the highest priority among all pagers triggered at the same time is selected as the target pager, so as to respond to the call of the target pager with the highest priority and ensure that critically ill patients can receive priority treatment.

[0064] In another possible implementation, the target path from the workstation to the target medical area where each target caller is located can be determined. If these target callers are not in the same target medical area, that is, the number of target paths is at least two, then an indication color can be set for each target path, so that the first indication device and / or the second indication device on the target path are lit with the indication color corresponding to the target path.

[0065] For example, assuming that there are two target paths, the indicator devices on one target path include the first indicator device a, the first indicator device b, the first indicator device c, and the second indicator device d, and the corresponding indicator color is blue; the indicator devices on the other target path include the first indicator device e, the first indicator device f, and the second indicator device g, and the corresponding indicator color is red. Thus, in the actual indication process, the first indicator device a, the first indicator device b, the first indicator device c, and the second indicator device d can be lit in blue, and the first indicator device e, the first indicator device f, and the second indicator device g can be lit in red.

[0066] In addition, it should be noted that when two target paths overlap, the first indicator device and / or the second indicator device of the overlapping portion may be lit in a preset common color, or in a corresponding indicator color that is switched alternately.

[0067] In one embodiment, in combination Figure 2 , Figure 6 FIG. 1 is a schematic diagram of the structure of another emergency guidance system provided by Embodiment 1 of the present invention. Figure 6 As shown, the emergency guidance system further includes: a monitor 106 .

[0068] The monitor 106 is electrically connected to the central controller 103 and is used to display the target path and the call information corresponding to the target caller, wherein the call information includes at least one of the current call state, call history information, and location information of the target medical area. The monitor 106 can facilitate medical staff to monitor the entire emergency treatment process.

[0069] In addition, the emergency guidance system may also include at least one of a broadcast and a signal transceiver. The broadcast may notify the corresponding medical personnel that an emergency rescue event has occurred, and the signal transceiver may not only assist in collecting the signal of the caller 101, but also realize communication with the land base station.

[0070] An embodiment of the present invention provides an emergency guidance system, which is arranged on a medical ship. The emergency guidance system includes a caller, an alarm, a central controller, a first indicator device, and a second indicator device. The caller is arranged in the medical area of ​​the medical ship, and the alarm is arranged at the door of the medical area. Once the patient in the medical area presses the target caller, the central controller will control all the alarms at the door of the target medical area where the target caller is located to alarm, so as to remind the medical staff of the location of the target medical area. At the same time, the central controller will also determine the target path from the workstation to the target medical area. The target path may include at least one channel and / or at least one channel door. Since each channel of the medical ship is provided with a first indicator device, and each channel door is provided with a second indicator device on both sides, the central controller lights up the first indicator device and / or the second indicator device on the target path, which can guide the medical staff from the workstation to the target medical area. In this way, the problem of delaying the rescue time due to the unfamiliarity of the medical staff with the cabin layout is avoided, the life safety of the patient is guaranteed, and the potential risk of medical disputes is eliminated.

[0071] Embodiment 2

[0072] Figure 7 is a flow chart of a path determination method provided in the second embodiment of the present invention. This embodiment is applicable to the scenario of planning a target path from a workstation to a target medical area. The method can be executed by a path determination device, which can be implemented in the form of hardware and / or software. The path determination device can be configured in the central controller of the emergency guidance system in the first embodiment. Figure 7 As shown, the method includes:

[0073] S710: Determine the location information of the target medical area where the target caller is located, wherein the target caller is a triggered caller.

[0074] Specifically, the path determination device can receive information sent by the target caller. In an optional implementation, the information can directly carry the location information of the target medical area where the target caller is located, and the path determination device can directly read the location information of the target medical area. In another optional implementation, the information can carry the identity (ID) of the target caller, and the path determination device determines the location information of the target medical area where the target caller is located based on the ID of the target caller.

[0075] S720. Obtain avoidance position information, wherein the avoidance position information includes global avoidance position information and / or priority avoidance position information, the global avoidance position information is used to indicate the currently inaccessible position information on the medical ship, and the priority avoidance position information is used to indicate the inaccessible position information corresponding to the priority of the target caller.

[0076] Due to the special nature of the medical ship, some of the original passages on the ship are actually impassable. It is impossible to accurately plan the path based on the original layout of the cabin alone. Therefore, it is necessary to combine the avoidance position information for route planning.

[0077] Specifically, the avoidance position information includes at least one of the following:

[0078] 1) Global avoidance position information.

[0079] The global avoidance position information is used to indicate the currently inaccessible position information on the medical ship, such as the position on the medical ship that is currently under maintenance, the position with special circumstances (such as cargo accumulation that is inaccessible), etc.

[0080] 2) Priority avoidance position information.

[0081] The priority avoidance position information is used to indicate the inaccessible position information corresponding to the priority of the target caller. For example, a target caller with a low priority (indicating a low urgency) cannot enter a restricted area from an unrestricted area.

[0082] Among them, restricted areas refer to areas that require isolation and disinfection before entry, or stairways leading to the outdoors or mechanical spaces.

[0083] S730. Determine a target path from the workstation to the target medical area according to the position information of the workstation, the position information of the target medical area, and the avoidance position information, wherein the target path does not overlap with the avoidance position information at all.

[0084] In combination with the above steps S710 - S720 , it can be seen that after obtaining the location information of the workstation, the location information of the target medical area and the avoidance location information, path planning can begin.

[0085] In an optional implementation, Figure 8 is a flow chart of another path determination method provided by Embodiment 2 of the present invention. Figure 8 As shown, the method of “determining a target path from a workstation to a target medical area” may include steps S730a-S730d.

[0086] S730a. Determine the original path from the workstation to the target medical area based on the preset topological relationship according to the location information of the workstation and the location information of the target medical area.

[0087] The topological relationship is obtained by taking each medical area as a node of the path graph and planning the relationship between nodes according to the cabin distribution. Usually, one medical ship corresponds to one topological relationship.

[0088] By taking the location information of the workstation as the starting point and the location information of the target medical area as the end point, the shortest path (ie, the original path) from the workstation to the target medical area can be determined based on the topological relationship.

[0089] S730b: Determine whether the original path does not overlap with the avoidance position information at all. If not, execute S730c; if yes, execute S730d.

[0090] However, due to the existence of the avoidance position information, the original path may not be passable at the current moment. Therefore, it is also necessary to verify whether the original path does not overlap with the avoidance position information at all. When the original path at least partially overlaps with the avoidance position information, it means that the original path is not passable at the current moment and the original path needs to be further optimized; when the original path does not overlap with the avoidance position information at all, it means that the original path is passable at the current moment and the original path is the shortest and optimal path.

[0091] S730c: Modify the original path and determine the target path.

[0092] When the original path at least partially overlaps with the avoidance position information, it means that the original path is not passable at the current moment and needs to be corrected (such as bypassing the avoidance position information, or determining the second shortest path from the workstation to the target medical area based on the topological relationship) to determine the target path.

[0093] S730d. Use the original path as the target path.

[0094] When the original path does not overlap with the avoidance position information at all, it means that the original path is passable at the current moment, and the original path is the shortest and optimal path. At this time, the original path can be used as the target path.

[0095] Since the topological relationship is preset in the path determination device, this implementation method does not require high computing power of the system and is easy to control costs.

[0096] In another optional implementation, Fig. 9 is a flow chart of another path determination method provided by the second embodiment of the present invention, such as Fig. 9 As shown, the method of “determining a target path from a workstation to a target medical area” may include steps S730e-S730f.

[0097] S730e. Obtain a pre-trained path planning model, wherein the path planning model is a model trained to determine the shortest path between two locations of the medical ship, subject to constraints.

[0098] In this implementation, the path planning model may be a model constructed using a genetic algorithm, a reinforcement learning algorithm, a taboo search algorithm, a simulated annealing algorithm, etc. The path planning model is a model trained with the goal of determining the shortest path between two locations of a medical ship subject to constraints.

[0099] S730f. Input the workstation's location information as the starting point, the target medical area's location information as the end point, and the avoidance location information as the constraint condition into the path planning model to obtain the target path.

[0100] By using the path planning model to plan the path, it can be ensured that the planning result is always the best (but not necessarily the shortest), that is, no correction steps are required and the result is output once. Therefore, this implementation method can save planning time and further ensure the life safety of patients.

[0101] The embodiment of the present invention provides a path determination method, including: determining the location information of the target medical area where the target caller is located, wherein the target caller is a triggered caller; obtaining avoidance location information, wherein the avoidance location information includes global avoidance location information and / or priority avoidance location information, the global avoidance location information is used to indicate the currently inaccessible location information on the medical ship, and the priority avoidance location information is used to indicate the inaccessible location information corresponding to the priority of the target caller; according to the location information of the workstation, the location information of the target medical area and the avoidance location information, determining the target path from the workstation to the target medical area, wherein the target path does not overlap with the avoidance location information at all. The technical solution of the embodiment of the present invention can reasonably plan the target path from the workstation to the target medical area, and provide a data basis for the application of the emergency guidance system.

[0104] The position determination module 1001 is used to determine the position information of the target medical area where the target caller is located, wherein the target caller is the triggered caller; obtain avoidance position information, wherein the avoidance position information includes global avoidance position information and / or priority avoidance position information, the global avoidance position information is used to indicate the currently inaccessible position information on the medical ship, and the priority avoidance position information is used to indicate the inaccessible position information corresponding to the priority of the target caller;
