Description

Technical Field

[0001] This application relates to the technical field of data processing, and particularly relates to a first-aid application service method, device, and electronic device based on path planning. Background Art

[0002] In daily life, accidental events such as drowning, traffic accidents, bites, choking, etc. are inevitable. When these accidental events occur, the most common way to seek help is to call the emergency number 120. However, in most cases, emergency patients are unable to make a call, and some are even unable to accurately describe their geographical location and condition. At the same time, in most rural areas, the emergency system is relatively backward, and due to reasons such as being far from the hospital, many critically ill patients cannot receive timely diagnosis and treatment.

[0003] Based on the above various situations, for various emergency patients, taking medicine in time, calling for help, and receiving timely rescue from doctors within the golden time of the best medication are the key to saving the patients' lives. In the context of the construction of intelligent healthcare, although some intelligent first-aid service systems have emerged, in the first-aid scenario, the knowledge system that needs to be processed by the system is very complex, and an accurate, timely, and effective service plan needs to be made according to the user's current situation.

[0004] Therefore, how to improve the accuracy of the first-aid application service and thus effectively improve the first-aid efficiency of at-risk personnel has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, the purpose of this application is to propose a first-aid application service method, device, and electronic device based on path planning, and this application can specifically solve the existing problems.

[0006] Based on the above purpose, in the first aspect, this application proposes a first-aid application service method based on path planning. The method includes: obtaining an input of a user based on a terminal device, where the input includes path selection information; obtaining a path structure matching the path selection information from a preset path table, where the path structure includes multiple nodes; performing path calculation according to whether the nodes in the path structure meet the node application conditions to obtain nodes to be expanded; executing the node tasks of the nodes to be expanded, and obtaining front-end display data according to the node types of the nodes to be expanded, where the node types include jump-type nodes and content-type nodes; obtaining feedback information of the user based on the front-end display data, and obtaining a first-aid evaluation result according to the feedback information.

[0007] Further, the multiple nodes included in the path structure have a hierarchical relationship. The nodes have sibling nodes and child nodes. Calculating a path to obtain a node to be expanded according to whether the nodes in the path structure meet the node application conditions includes: expanding the nodes one by one level by level according to the hierarchical relationship of the nodes in the path structure, and calculating whether the nodes meet the node application conditions; when a node meets the node application conditions, using the node that meets the node application conditions as the node to be expanded, and judging whether the child nodes of the node that meets the node application conditions meet the node application conditions, and sequentially traversing all child nodes; when a node does not meet the node application conditions, judging whether the sibling nodes of the node meet the node application conditions, and sequentially traversing all sibling nodes of the node; using the expansion order of the nodes that meet the node application conditions as the sorting of the nodes to be expanded, and forming a set of nodes to be expanded.

[0008] Further, when the node to be expanded is a jump type node, executing the node task of the node to be expanded and obtaining front-end display data according to the node type of the node to be expanded includes: judging the sub-type of the jump type node, where the sub-types of the jump type node include tab jump and pop-up window jump; when the sub-type is tab jump, opening the tab interface according to the opening state of the tab; where in the state where the tab is not opened, opening a new content tab in the current content frame; in the state where the tab is opened, jumping to the corresponding opened tab; when the sub-type is pop-up window jump, opening a preset pop-up window corresponding to the jump type node in the current content frame.

[0009] Further, when the node to be expanded is a content type node, executing the node task of the node to be expanded and obtaining front-end display data according to the node type of the node to be expanded includes: obtaining the node content matching the content type node from a preset node table, expanding the node content in sequence according to a preset display order, and assembling all the node content of the node to be expanded into complete front-end display data; where the node content includes content formed by arbitrarily combining 8 types of data modes, namely soothing words, guiding words, inquiry words, situation judgment, prompt information, important prompt, video pictures, and tool links.

[0010] Further, the input by the user based on the terminal device includes the chief complaint information. Before performing path calculation based on whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded, the method includes: obtaining the chief complaint information of the user; performing word segmentation processing on the chief complaint information to obtain a plurality of phrases, and obtaining a first estimated risk result matching the phrases according to a preset risk matching table; or performing semantic analysis on the chief complaint information to obtain a second estimated risk result; and obtaining a path structure matching the first estimated risk result or the second estimated risk result from a preset path table.

[0012] Further, the content-based node is associated with question options based on the current event to be answered by the user. The feedback information of the user based on the front-end display data includes the question results of the user for the question options. Obtaining the feedback information of the user based on the front-end display data and obtaining an emergency assessment result according to the feedback information includes: obtaining a question result set composed of the question results; matching the question result set with a cross-chain assessment set in a preset event assessment table to obtain a first assessment result set, where the cross-chain assessment set includes question options associated with nodes from multiple path structures; matching the question result set with an in-chain assessment set of the preset event assessment table to obtain a second assessment result set, where the in-chain assessment set includes question options associated with nodes from the same path structure; obtaining the union of the first assessment result set and the second assessment result set, sorting according to the weights in the preset event assessment table, and using the risk rating corresponding to the assessment result with the highest weight as the emergency assessment result of the current event.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the convenience of description, only parts related to the invention are shown in the drawings.

[0036] 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. The present application will be described in detail below with reference to the drawings and embodiments.

[0037] Figure 1 Shows a flowchart of the steps of a first-aid application service method based on path planning of the present application. The execution subject of this method can be a server or an electronic device. An emergency application APP is installed on the electronic device, and the user can achieve human-computer interaction through the APP, such as inputting a description of the current patient's condition.

[0038] In the embodiments of the present application, referring to Figure 1 , this method includes the following steps S101 to S105:

[0039] S101. Obtain the input of the user based on the terminal device.

[0040] In this embodiment, the input of the user based on the terminal device includes path selection information. The path selection information is a direct selection of a user for a certain medical path. For example, the server displays path options such as the trauma path, the accident path, and the common disease path to the user through the terminal device, and the user can select one or more of these path options.

[0041] In one example, the scenario corresponding to the input of the user based on the terminal device being path selection information is a scenario of directly starting the path, that is, after the user inputs the path selection information, the system directly enters the calculation of this path.

[0042] S102. Obtain a path structure that matches the path selection information from a preset path table. The path structure includes multiple nodes.

[0043] In this embodiment, a node is a knowledge node. A knowledge node is the smallest unit for path calculation. That is, after meeting a certain path planning condition, the content contained in a certain node needs to be used as a whole. Multiple nodes form a path. Therefore, a knowledge node is the smallest logical unit for knowledge application.

[0044] In this embodiment, a path refers to a network node organization form composed of a kind of knowledge nodes. Specifically, a path can express the vector link relationship between different knowledge nodes and the application conditions of different nodes. According to different usage scenarios, paths can be divided into: supplementary description, event inquiry, first aid guidance, etc. In an actual path, the role of the path is diverse. For example, there is a path that includes event inquiry, first aid guidance, and supplementary description at the same time. The specific role of the path is determined by the application conditions of the path and the specific content of the knowledge nodes included in the path.

[0045] In an example, supplementary description is to supplement a certain situation of the current event through the combination of a series of knowledge nodes, or to expand and explain a certain problem, or to supplement a certain first aid guidance. For example, a specific diagram is given, and the diagram is used to inform the user of the area to which a certain location belongs, so as to facilitate the positioning of the injured area.

[0046] Event inquiry is to ask the user questions or prompt the user to make a judgment on the on-site situation through the combination of a series of knowledge nodes, so as to facilitate subsequent further first aid guidance processing. For example, asking the user about the specific injured part of the injured person.

[0047] First aid guidance is to provide first aid guidance for a certain situation of the current event through the combination of a series of knowledge nodes. Usually, based on a certain judgment of the user or some on-site situations that have been known, reasonable first aid guidance content is given. For example, giving the suggestion to let the injured person lie flat in a ventilated area.

[0048] In this embodiment, a path table, a risk matching table, a node table, etc. can be preset in the database of the server to facilitate path calculation and node calculation, etc. in this embodiment. The path table includes a path structure, and the relationship structure of the path structure in the graph database is as Figure 2 shown, where, in the graph database, the path structure is manifested as a vector connection relationship between a series of nodes. As Figure 2As shown, in the choking (estimated) path PRC2207271614480001, there are 3 nodes: node PNC2207271627400001, node PNC2207271627400002, and node PNC2207271627400003. Among them, PRC2207271614480001 is the path number (Route_Code), and PNC2207271627400001, PNC2207271627400002, and PNC2207271627400003 are node numbers (Node_Code).

[0049] Node PNC2207271627400002 has a vector link relationship with node PNC2207271627400001, and node PNC2207271627400003 has a vector link relationship with node PNC2207271627400001. That is, there are 3 knowledge nodes and 2 edges formed by vector relationships in this path.

[0050] The relationship structure of the path structure in the relational database is as Figure 3 shown. Among them, in the relational database, the path is represented as a tree-like structure relationship between a series of nodes, and the relationship between nodes is described by parent nodes and child nodes. As Figure 3 shown, in the choking (estimated) path PRC2207271614480001, there are 3 nodes: node PNC2207271627400001, node PNC2207271627400002, and node PNC2207271627400003. Among them, node PNC2207271627400001 has no parent node, and node PNC2207271627400001 has 2 child nodes, PNC2207271627400002 and PNC2207271627400003. Node PNC2207271627400002 has a parent node PNC2207271627400001 and no child nodes. PNC2207271627400003 has a parent node PNC2207271627400001 and no child nodes.

[0051] As Figure 3As shown in the figure, where Node_Code is the node number, Route_Code is the path number, and Question_Code is the question number. The remarks include whether the risk assessment of the current path belongs to estimated risk or determined risk. Among them, the estimated risk is the risk result calculated by the system and directly provides interaction to the user by matching the path. During this process, the estimated risk is not presented to the user and belongs to the intermediate calculation process of the background logic. The determined risk includes the risk recommendation result calculated by the system and the risk result obtained by the user based on their own judgment. The determined risk must be manually selected by the user before matching the path and performing subsequent interactions. During this process, the determined risk must be the content confirmed by the user himself, but the system can make recommendations through algorithms, and the final result is subject to the actual selection of the user.

[0052] Figure 4 is the structural schematic table of path nodes, as Figure 4 shown. In this embodiment, the node types of path nodes include jump nodes and content nodes. The content nodes include content type, rich text content, associated questions, and URLs. For content nodes, users can see their specific content. According to the type of content displayed by the content nodes, they can be further divided into "main content" and "sub-content". The display area of the terminal device can be divided into a main content area and a sub-content area, and the main content will be displayed in the main content area, and the sub-content will be displayed in the sub-content area.

[0053] Among them, the associated questions included in the content nodes are question options for a certain event. These question options are constructed based on the medical knowledge system and are used to obtain the current information of the user in order to make a correct judgment. For example, in the nodes of the choking path, the questions included are "consciousness judgment" and "breathing judgment". For the option of "consciousness judgment", the options include "unconscious", "conscious", and "unable to judge", and for the option of "breathing judgment", the options include "no breathing", "breathing", and "unable to judge". When the user feedbacks the question results for the above questions under the current event, the system can evaluate the current state of the injured according to the user's question results.

[0054] Figure 5 is the structure of the questions included in the nodes, as Figure 5 shown. The content of the questions includes: options, option values, option labels, and option identifiers. This part of the content has global commonality, that is, the same questions in different paths or nodes are unified.

[0055] Among them, the options include A / B / C / D, etc., which are used to logically define the values of the options or directly used for option judgment logic;

[0056] The option values include judgment option values such as "cannot" or "can", which are presented to the user so that the user can make a selection.

[0057] Option labels, such as "cannot speak or breathe normally", are presented to the user so that the user can see the option results on the work order backtracking page. The work order backtracking page is a backtracking page given by the system after the user completes the current event and contains the evaluation results of the current event. The role of the option label is to enable the user to understand the meaning of the problem result without looking at the problem stem.

[0058] The option identifier is a special option identifier for external system docking. The option identifier is defined by the external system. The external system can be connected to the system using the path planning-based first aid application service method of this embodiment through the API service interface.

[0059] It should be noted that the problems in this embodiment and the problem results feedback by the user can cross the limitations of paths and nodes to achieve the sharing of problems. For example, problem α is included in node A in path 1, and at the same time, problem α can also be included in node B in path 2. Even if the complete content of node A and node B or the way of asking problem α may be different, when the answer α-A is obtained for problem α in node A of path 1, the problem α in node B of path 2 synchronously obtains the answer α-A, that is, problem α realizes the global synchronization effect across paths and nodes. This can avoid the situation where users repeatedly answer the same question in multiple paths, shorten the inquiry time, and also improve the system calculation speed.

[0060] In this embodiment, the specific function of the jump node is to perform jump links between paths or between paths and front-end functions. For example, after meeting a certain specific condition, enter the end jump node of the path. After the user performs this condition operation on the front end, a work order end pop-up window will appear.

[0061] Figure 6 A schematic diagram showing the relevance between the content node and the problem is given. Refer to Figure 6 , in this embodiment, each problem is set with a corresponding problem code, and the content node also has a corresponding node code. Then, the association between the content node and the problem can be realized by associating the node code of the content node with the problem code.

[0062] In this embodiment, the path structure matching the path selection information is obtained from the preset path table. For example, if the path selection information input by the user is the choking path, and the choking path is preset in the path table, after the user inputs the path selection information, the system obtains the path information corresponding to the choking path from the path table, including all node information of the path.

[0063] Figure 6In it, the schematic diagram of the relevance between content nodes and questions gives the relevance serial number between content nodes and questions, content node number Content_Code, node number Node_Code, content type, rich text content, question number Question_Code, URL, remarks including path nodes, and remarks 2 indicating the evaluation risk result. For example, for the content node with serial number 2, the content node number Content_Code is PCC2207271627400002, the node number Node_Code is PNC2207271627400001, the content type is inquiry words, the rich text content is "Can he speak or breathe normally?", the question number Question_Code is PQC2207271627400001, there is no URL, the path node is PRC2207271614480001, and the remarks 2 indicating the evaluation risk result is choking (estimated).

[0064] S103. Perform path calculation according to whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded.

[0065] In this embodiment, the node application conditions are used to control whether the node can be enabled. The node can be enabled if and only if the node meets the node application conditions. For content nodes, the manifestation of the node being enabled is that the user can see the specific content of this content node after meeting the node application conditions. For jump nodes, the manifestation of the node being enabled is that after meeting the node application conditions, it can jump to other paths, end pop-ups, specified tabs and other target links.

[0066] It should be noted that due to the path relationship between nodes, if the "parent node" of node N is in the "disabled" state, then regardless of whether node N meets the enabling conditions of this node, node N is still "disabled". If node N has multiple parent nodes, and any one of the parent nodes of node N is "enabled", then node N can directly determine its own state of whether it meets the node enabling conditions.

[0067] In this embodiment, the node application conditions include unconditional, option combination, evaluation result, click to provide, and composite logic, a total of 5 types. Unconditional means this item is empty, and its meaning is that the node is in the "enabled" state in any case.

[0068] Option combination is the option combination of questions. This condition needs to point out the specific option combination method of specific questions, and supports the combination of multiple questions and multiple options. For example, node A will be enabled only when questions α and β are combined.

[0069] The evaluation result is a combination of evaluation results. In this condition, the specific set of evaluation results needs to be pointed out, supporting the combination method of single or multiple evaluation results. It can be understood that in the actual first-aid environment, the patient may have multiple symptoms. For example, according to the bleeding condition of the patient's limb, the first evaluation result that the user belongs to trauma can be obtained, and according to the patient's breathing and clear consciousness, the second evaluation result that the user's condition is stable can be obtained. The node application condition of node B is that node B will be enabled only when the first evaluation result and the second evaluation result are both satisfied. Then, when the evaluation results include both the first evaluation result and the second evaluation result, node B will be enabled.

[0070] Click to provide means that the user enables the node by clicking on a certain node. It can be that the user selects the problem options existing in the node. If there are no problem options in the node, it can be that the user clicks on the area where the node is located.

[0071] Compound logic is the compound logic that comprehensively applies the above-mentioned node application condition logics of unconditional, option combination, evaluation result, and click to provide.

[0072] In this embodiment, as Figure 3 shown, the multiple nodes included in the path structure have a hierarchical relationship. The nodes have sibling nodes and child nodes. In this embodiment, as Figure 7 shown, according to whether the nodes in the path structure meet the node application conditions, the nodes to be expanded are obtained, including the following steps S701 to S704:

[0073] S701. According to the hierarchical relationship of the nodes in the path structure, expand the nodes one by one level by level, and calculate whether the nodes meet the node application conditions.

[0074] It can be understood that a complete path structure contains multiple knowledge nodes that can realize the functions realized by the path structure. In the current event that the user is performing, it may not contain all the knowledge nodes of the path structure. In this case, some knowledge nodes do not need to be enabled. Therefore, in this embodiment, first, all the nodes in the current path structure are expanded one by one according to the hierarchical relationship of the nodes in the path structure, and then each node is judged in turn to calculate whether the node meets the node application conditions. Whether the node meets the node application conditions is judged by determining whether the current event meets the five node application conditions of unconditional, option combination, evaluation result, click to provide, and compound logic described above, which will not be elaborated here. Of course, in an example, other node application conditions can also be set according to actual business requirements.

[0075] S702. When the node meets the node application conditions, the node that meets the node application conditions is used as the node to be expanded, and it is judged whether the child nodes of the node that meets the node application conditions meet the node application conditions, and all the child nodes are traversed in turn.

[0076] For example, if node 1 meets the node application conditions, it is necessary to further determine whether the child nodes of node 1 meet the node application conditions, or determine the nodes that have a vector link relationship with node 1. If node 1 meets the node application conditions, node 1 is used as the node to be expanded. At the same time, it is determined whether the child nodes of the child nodes of node 1 meet the node application conditions, and all the child nodes included in the lower level of node 1 are traversed in turn.

[0077] S703. In the case where the node does not meet the node application conditions, determine whether the sibling nodes of the node meet the node application conditions, and traverse all the sibling nodes of the above node in turn.

[0078] It can be understood that step S702 determines the node application conditions for the child nodes or the child nodes of the child nodes of node 1 in turn, which belongs to vertical extension processing. And step S703 is the horizontal extension of node 1. In the case where node 1 does not meet the node application conditions, it is determined whether the sibling nodes of node 1 meet the node application conditions, and all the sibling nodes of node 1 are traversed in turn. When determining the node application conditions for the sibling nodes of node 1, the methods shown in steps S702 and S703 can also be used to realize the traversal of all nodes in the path structure.

[0079] S704. Use the expansion order of the nodes that meet the node application conditions as the sorting of the nodes to be expanded, and form a set of nodes to be expanded.

[0080] After calculating by the methods of steps S702 and S703, all the nodes that meet the node application conditions in the current path structure can be obtained. Then, in this embodiment, the expansion order of all the nodes that meet the node application conditions is used as the sorting of the nodes to be expanded, and a set of nodes to be expanded is formed. It should be noted that the nodes in the set of nodes to be expanded do not have a hierarchical relationship, but have a sequence.

[0081] S104. Execute the node tasks of the nodes to be expanded, and obtain the front-end display data according to the node types of the nodes to be expanded.

[0082] In this embodiment, the node types include jump nodes and content nodes. The node tasks are determined according to the node types. For example, when the node is a jump node, the node task is to jump to the corresponding address page of the node. When the node is a content node, the node task is to display the content included in the content node to the user. It can be understood that for different node types, the ways of executing node tasks are also different.

[0083] In the case where the node to be expanded is a jump node, executing the node task of the node to be expanded and obtaining the front-end display data according to the node type of the node to be expanded includes:

[0084] Determine the subtype of the jump node. The subtypes of the jump node include tab jump and pop-up window jump. In the case where the subtype is tab jump, open the tab interface according to the opening state of the tab. Among them, in the state where the tab is not opened, open a new content tab in the current content framework. In the state where the tab is opened, jump to the corresponding opened tab. At this time, the front-end display data is the tab interface corresponding to the node.

[0085] In the case where the subtype is pop-up window jump, open the preset pop-up window corresponding to the jump node in the current content framework. At this time, the front-end display data is the preset pop-up window corresponding to the node.

[0086] And in the case where the node to be expanded is a content node, execute the node task of the node to be expanded, and obtain the front-end display data according to the node type of the node to be expanded, including: obtaining the node content matching the content node from the preset node table, expanding the node content in the preset display order in sequence, and assembling all the node content of the node to be expanded into the complete front-end display data. Among them, the node table contains Figure 4 or Figure 5 the content shown.

[0087] In this embodiment, the node content includes content composed of 8 types of data modes, namely soothing words, guiding words, inquiry words, situation judgment, prompt information, important prompt, video pictures, and tool connections, combined in any order.

[0088] Among them, the soothing words only contain rich text content, which is the text content used to guide the user to soothe the on-site caller. For example, the soothing words are "Don't panic, please handle it according to my guidance", etc.

[0089] The guiding words only contain rich text content, which is the text content used to guide the user to provide first aid guidance and related methods for the on-site caller. For example, the guiding words are "Try not to move the injured part as much as possible and keep the original position" or "Please stay with the injured person and pay attention to the change of his injury at any time. If the situation deteriorates, please tell me immediately", etc.

[0090] The inquiry words contain rich text content and associated questions. When presented to the user, these two parts need to be spliced and presented to the user, which is the text content used to guide the user to ask questions to the on-site caller. For example, the associated question is "Does the injured person have severe bleeding or bleeding?" The rich text content is the question options "Severe bleeding", "Minor bleeding", "Unable to judge", "No bleeding".

[0091] The situation judgment includes rich text content and associated questions. When presenting to the user, these two parts need to be concatenated and presented to the user. It is the text content used to require the user to make a judgment on the on-site situation. For example, the associated question is "Whether the condition of the injured has deteriorated", and the rich text content is the question options "Loss of breathing and consciousness", "Loss of consciousness with breathing", "Severe bleeding that does not stop", "Condition stable".

[0092] The prompt message only includes rich text content; it is the text content used to prompt the user's operation precautions or the next processing method. For example, "If the injured has multiple parts injured, please select the most serious part or multiple parts. If multiple parts are selected, please describe the specific injured parts in the remarks."

[0093] The important prompt only includes rich text content; it is the text content used to emphasize important execution steps or risks to the user. For example, "If there are flammable and explosive substances, the vehicle is smoking or on fire, the vehicle is wading in water, etc. at the scene, please be sure to confirm whether there are people trapped in the vehicle."

[0094] The video and picture include rich text content and URL. The rich text content is the picture title, and the URL is the picture link; it is the graphic and text content used to explain the inquiry questions or first aid guidance to the user and the on-site rescuer. The example pictures show the basic body parts structure, including the front and back.

[0095] The tool connection includes rich text content and URL. The rich text content is the name of the small tool, and the URL is the link of the small tool; it is the tool connection used to assist the user in performing certain operations. After clicking, it can jump to the corresponding small tool interface. For example, the small tool is a frequency counting tool used to help the user measure the heart rate of the injured.

[0096] S105. Obtain the feedback information of the user based on the front-end display data, and obtain the first aid evaluation result according to the feedback information.

[0097] In this embodiment, the content-based node is associated with the question options based on the current event to be answered by the user. The feedback information of the user based on the front-end display data includes the question results of the user for the question options. Figure 8 Shows a schematic diagram of the interface of the front-end display data, as Figure 8 shown. This scenario corresponds to the trauma scenario, and the corresponding path is the trauma path. The front-end display data includes multiple question options and supplementary guiding content. The user makes a feedback based on the question options provided by the front-end display data. After the system receives the feedback information, it obtains the first aid evaluation result according to the feedback information. Among them, the feedback information is the question result of the user based on the question options.

[0098] In this embodiment, a risk matching table is preset in the system, and the risk matching table contains fields of evaluation results. Figure 9Shows the field composition of an evaluation result. The content of the evaluation result includes: evaluation result, type, path encoding, logic, and rating. Among them,

[0099] The evaluation result is the Chinese name of the evaluation result, used for name display during front-end display and back-end maintenance.

[0100] The type includes two types: cross-chain evaluation and in-chain evaluation, aiming to reduce the retrieval of invalid evaluation results and improve the matching efficiency of evaluation results. Cross-chain evaluation means that the question options constituting the evaluation result logic may come from multiple paths. In-chain evaluation means that all the question options constituting the evaluation result logic come from the same path.

[0101] The path encoding is used in conjunction with "in-chain evaluation", indicating that all the questions constituting the evaluation logic come from this path.

[0102] The logic is the combination logic of the question options of this evaluation result.

[0103] The rating is the medical evaluation level of this evaluation result, divided into 4 levels, namely: 4 - Critical, 3 - Urgent and Critical, 2 - Emergency, 1 - Minor Illness.

[0104] In this embodiment, obtain the feedback information of the user based on the front-end display data, and obtain the first-aid evaluation result according to the feedback information, including: obtaining the question result set composed of question results; matching the question result set with the cross-chain evaluation set in the preset event evaluation table to obtain the first evaluation result set, and the cross-chain evaluation set includes the question options associated with the nodes from multiple path structures; matching the question result set with the in-chain evaluation set of the preset event evaluation table to obtain the second evaluation result set, and the in-chain evaluation set includes the question options associated with the nodes from the same path structure; obtaining the union of the first evaluation result set and the second evaluation result set, and sorting according to the weights of the preset event evaluation table, and taking the risk rating corresponding to the evaluation result with the highest weight as the first-aid evaluation result of the current event.

[0105] In this embodiment, the evaluation result is a judgment result based on the question result, used to comprehensively analyze the question result in this event according to the medical logic, so as to achieve the purpose of medical classification and grading for the event. In this embodiment, the evaluation result can be calculated according to the feedback result of the user. The specific calculation method can be to count all the question results of the question options included in the calculation logic that meets a certain evaluation result, and then obtain the corresponding evaluation result through the calculation logic of the evaluation result.

[0106] For example, if the question is "Is there breathing?", and the option result is "No breathing"; for the question "Is there consciousness?", and the option result is "Unconscious", at this time, the two option answers can be combined to generate an evaluation result of "Loss of breathing and consciousness", with a rating of "Critical". Such an evaluation result and rating have clinical or first aid significance. At this time, the combination of the option result of "No breathing" and the option result of "Unconscious" is the judgment logic for the evaluation result. This logic can be determined based on the medical knowledge system.

[0107] Such an evaluation result and rating have clinical or first aid significance. At the same time, the evaluation result can be used as a node application condition when making path judgments. That is, in step S103, when calculating the path based on whether the nodes in the path structure meet the node application conditions to obtain the node to be expanded, this evaluation result can be used as part of the node application condition.

[0108] In this embodiment, the evaluation results formed by the combinations of different question results of different paths are medically equivalent. For example, in path 1, question α - A and question β - B can be combined into an evaluation result A0001, and in path 2, question π - C can also be combined into an evaluation result A0001. The evaluation results obtained by these two path combination methods are also globally equivalent.

[0109] The above is the scenario where the user's input is path selection information in a first aid application service method based on path planning provided in this embodiment. That is to say, the user knows the specific situation of the current injured person and can directly select the corresponding path and enter. When the user is not clear about the situation of the current injured person, the user can obtain first aid services by entering the chief complaint information. Figure 10 A schematic diagram of an interface for entering the chief complaint information is shown. The user can enter the chief complaint information in the chief complaint information box on the chief complaint page, such as "The old person choked while eating". At the same time, in order to facilitate medical staff to contact and rescue the injured person, the user can enter basic information such as name, address, and contact information. The user can also fill in the question options such as the identity of the alarm caller, whether they are beside the patient, the gender of the patient, and the judgment of consciousness and breathing, etc., in order to estimate the preliminary situation of the patient.

[0110] That is, the current scenario is a scenario of an estimated risk path where the user is not clear about the specific risks of the patient.

[0111] In this embodiment, the user's input based on the terminal device includes the chief complaint information. Before calculating the path according to whether the nodes in the path structure meet the node application conditions to obtain the node to be expanded, refer to Figure 11 , the method of this embodiment includes the following steps S1101 to S1104:

[0112] S1101. Obtain the chief complaint information of the user.

[0113] As Figure 10 shown, the chief complaint information is the specific situation of the current injured person input by the user. For example, the chief complaint information is "The old person choked while eating".

[0114] S1102. Perform word segmentation on the chief complaint information to obtain multiple phrases, and according to a preset risk matching table, obtain a first estimated risk result that matches the phrases.

[0115] It can be understood that the chief complaint information can be a sentence composed of multiple words or multiple sentences. In order to quickly obtain an estimated risk based on the chief complaint information, an estimated risk can be defined in advance according to the words. Then, perform word segmentation on the chief complaint information to obtain multiple phrases, and then according to the preset risk matching table, obtain a first estimated risk result that matches the phrases.

[0116] For example, if the chief complaint information is "The old person choked", then directly obtain from the risk matching table according to the word "choked" that the first estimated risk result is choked (estimated).

[0117] S1103. Perform semantic analysis on the chief complaint information to obtain a second estimated risk result.

[0118] It can be understood that when there is no word in the chief complaint information that is the same as the words in the risk matching table, but its meaning is expressed, then by performing semantic analysis on the chief complaint information, obtain a second estimated risk result that matches the meaning of the chief complaint information.

[0119] For example, if the chief complaint information is "The old person choked while eating", then according to the phrase "choked while eating", the second estimated risk result can be obtained as "choked" (estimated).

[0120] That is to say, in this embodiment, step S1102 and step S1103 are in a parallel relationship. The estimated risk result can be obtained according to step S1102, or the estimated risk result can be obtained according to step S1103.

[0121] S1104. Obtain a path structure that matches the first estimated risk result or the second estimated risk result from a preset path table.

[0122] After obtaining the estimated risk result through step S1102 or step S1103, it is necessary to further determine the specific path structure according to the estimated risk result. The path table in this embodiment is the path table in step S102. By looking up the table, the path structure that matches the estimated risk result can be obtained.

[0123] For example, in this embodiment, the estimated risk path scenario executes step S1102 to obtain a first estimated risk result. The first estimated risk result is heart disease, then obtain the path structure that matches heart disease from the preset path table.

[0124] After obtaining the path structure, step S103 can be executed to perform path calculation based on whether the nodes in the path structure meet the node application conditions, and obtain the steps of the nodes to be expanded.

[0125] The above is for the scenario of estimating risk paths, and its overall method includes steps S1101 - S1104 and steps S103 - S105.

[0126] In this embodiment, there is also a standard process path scenario. The standard process path scenario can combine the judgment of the system and the judgment of the user to obtain a determined risk, which has better service accuracy. Among them, the determined risk includes the recommended risk result calculated by the system and the risk result obtained by the user based on their own judgment. The determined risk must be manually selected by the user before matching the path and performing subsequent interactions, and the final result is subject to the actual selection of the user. For example, the user Figure 10 selects the system-recommended risk through the event risk box on the interface, thereby determining the risk result.

[0127] Then in this embodiment, before performing path calculation based on whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded, as Figure 12 shown, the method includes the following steps S1201 - S1206:

[0128] S1201. Obtain the chief complaint information of the user.

[0129] As Figure 10 shown, the chief complaint information is the specific situation of the current injured person input by the user. For example, the chief complaint information is "The old person choked while eating".

[0130] S1202. Perform word segmentation on the chief complaint information to obtain multiple phrases, and obtain the first determined risk result matching the phrases according to the preset risk matching table.

[0131] It can be understood that the chief complaint information can be a sentence composed of multiple words or multiple sentences. In order to quickly obtain the estimated risk based on the chief complaint information, an estimated risk can be defined in advance according to the words. Then, perform word segmentation on the chief complaint information to obtain multiple phrases, and then obtain the first determined risk result matching the phrases according to the preset risk matching table.

[0132] For example, if the chief complaint information is "The old person choked", then directly obtain the first determined risk result as choking (estimated) from the risk matching table according to the word "choking".

[0133] S1203. Perform semantic analysis on the chief complaint information to obtain the second determined risk result.

[0134] It can be understood that when there is no word in the chief complaint information that is the same as the word in the risk matching table, but its meaning is expressed, the second determined risk result that matches the meaning of the chief complaint information is obtained by semantic analysis of the chief complaint information.

[0135] For example, if the chief complaint information is "The old person choked while eating", then according to the phrase "choked", the second determined risk result can be obtained as "choking" (estimated).

[0136] It should be noted that the difference between the first estimated risk result and the first determined risk result in this embodiment, and the difference between the second estimated risk result and the second determined risk result is that the first estimated risk result and the second estimated risk result are estimated data calculated by the system and are not directly shown to the user, while the first determined risk result and the second determined risk result can be pushed to the user for the user to freely choose.

[0137] S1204. Display the first determined risk result or the second determined risk result to the user.

[0138] For example, through Figure 10 The event risk box on the interface recommends the first determined risk result or the second determined risk result to be selected to the user.

[0139] S1205. Receive the selection result of the user for the first determined risk result or the second determined risk result.

[0140] In this embodiment, after the user selects the first determined risk result or the second determined risk result as the selection result, it indicates that the user agrees with the risk result recommended by the system. The system then performs further calculations based on the selection result.

[0141] S1206. Obtain the path structure that matches the selection result from the preset path table.

[0142] For example, in this embodiment, the selection result is the second determined risk result, and the second estimated risk result is choking. Then, the path structure that matches choking is obtained from the preset path table.

[0143] After obtaining the path structure, step S103 can be executed to perform path calculation according to whether the nodes in the path structure meet the node application conditions to obtain the steps of the nodes to be expanded.

[0144] The above is for the standard risk path scenario, and its overall method includes steps S1201 to S1206 and steps S103 to S105.

[0145] It should be noted that all the data generated during the calculation process of this embodiment can be cached by the data cache unit. The data cache unit is connected to the database to retrieve the data in the database. The data retrieved and stored by the data cache unit is used to implement the calculation of path planning.

[0146] In one example, the system framework for implementing the first-aid application service method based on path planning of this embodiment is as Figure 13 shown. The system architecture includes an interface interaction module, a calculation module, a data cache module, and a database. Among them, the database pre-stores data tables such as a risk matching table, a path table, a node table, and an event evaluation table.

[0147] The data cache module includes an intermediate result cache module, a path result cache, and a node content cache module. The intermediate result cache module and the path result cache are used to cache the interaction results with the user, so as to facilitate the extraction of a certain data when needed. The node content cache module is used to cache the expanded content of the node to facilitate the calculation of the node.

[0148] The calculation module includes a parameter calculation module, a path calculation module, and a node calculation module. Among them, the parameter calculation is used to obtain the user's input and perform calculations according to the user's input. For example, it executes the method of step S105 in the above embodiment. The path calculation module is used to perform calculations related to the path. For example, it executes step S102 to obtain the path structure that matches the path selection information from the preset path table. The node calculation module is used to perform calculations related to the node. For example, it executes step S103 to perform path calculation according to whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded.

[0149] The interface interaction module includes a user interaction information input module and a visualization interface presentation module. Among them, the user interaction information input module is used to implement the interaction. For example, the user interaction information input module executes step S101 to obtain the user's input based on the terminal device. The visualization interface presentation module is used to present the information to be displayed to the user. For example, the visualization interface presentation module executes step S104 to execute the node task of the node to be expanded and obtain the front-end display data according to the node type of the node to be expanded.

[0150] The above are the overall steps of a first aid application service method based on path planning provided by this embodiment. When the input of the user based on the terminal device includes path selection information, directly start the path planning route corresponding to the path selection information. Specifically, obtain the path structure matching the path selection information from a preset path table, and the path structure includes multiple nodes; perform path calculation according to whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded; execute the node tasks of the nodes to be expanded, and obtain the front-end display data according to the node types of the nodes to be expanded, where the node types include jump nodes and content nodes; obtain the feedback information of the user based on the front-end display data, and obtain the first aid evaluation result according to the feedback information. It can realize the connection relationship of complex knowledge networks, and process different path judgments under complex logical conditions, so as to ensure that the system can make the most appropriate immediate feedback, provide the correct path, obtain accurate first aid evaluation results, improve the accuracy of the first aid application service, and thus effectively improve the first aid efficiency of risk personnel.

[0151] When the input of the user based on the terminal device includes the chief complaint information, adapt the estimated risk path scenario and the standard process path scenario, which can realize that no matter what information the user inputs, the final path structure can be obtained, and support the calculation of complex dynamic logic and knowledge network relationships.

[0152] The application embodiment provides a first aid application service device based on path planning. The first aid application service device based on path planning is used to execute the first aid application service method based on path planning described in the above embodiment. Figure 14 Show a structural schematic diagram of a first aid application service device based on path planning according to an embodiment of the present application. As Figure 14 shown, the first aid application service device 1400 based on path planning includes:

[0153] A data acquisition module 1401, configured to acquire the input of the user based on the terminal device, where the input includes path selection information;

[0154] A path matching module 1402, configured to obtain a path structure matching the path selection information from a preset path table, where the path structure includes multiple nodes;

[0155] A path calculation module 1403, configured to perform path calculation according to whether the nodes in the path structure meet the node application conditions to obtain the nodes to be expanded;

[0156] The node processing module 1404 is used to execute the node tasks of the node to be expanded, and obtain front-end display data according to the node type of the node to be expanded, where the node type includes jump nodes and content nodes;

[0157] The evaluation module 1405 is used to obtain the feedback information of the user based on the front-end display data, and obtain the first-aid evaluation result according to the feedback information.

[0158] In an example, the multiple nodes included in the path structure have a hierarchical relationship, the nodes have sibling nodes and child nodes, and the path calculation module 1403 is further used to: expand the nodes one by one level by level according to the hierarchical relationship of the nodes in the path structure, and calculate whether the nodes meet the node application conditions; in the case that the nodes meet the node application conditions, use the nodes that meet the node application conditions as the nodes to be expanded, and judge whether the child nodes of the nodes that meet the node application conditions meet the node application conditions, and traverse all child nodes in turn; in the case that the nodes do not meet the node application conditions, judge whether the sibling nodes of the nodes meet the node application conditions, and traverse all sibling nodes of the nodes in turn; use the expansion order of the nodes that meet the node application conditions as the sorting of the nodes to be expanded, and form a set of nodes to be expanded.

[0159] In an example, the node processing module 1404 is further used to: judge the subtype of the jump node, where the subtype of the jump node includes tab jump and pop-up window jump; in the case that the subtype is tab jump, open the tab interface according to the opening state of the tab; where in the state where the tab is not opened, open a new content tab in the current content framework; in the state where the tab is opened, jump to the corresponding opened tab; in the case that the subtype is pop-up window jump, open a preset pop-up window corresponding to the jump node in the current content framework.

[0160] In an example, the node processing module 1404 is further used to: obtain the node content matching the content node from a preset node table, expand the node content in sequence according to a preset display order, and assemble all the node content of the node to be expanded into complete front-end display data; where the node content includes content formed by any order combination of 8 types of data modes such as soothing words, guiding words, inquiry words, situation judgment, prompt information, important prompt, video pictures, and tool connections.

[0161] In one example, the input by the user based on the terminal device includes the chief complaint information. The path matching module 1402 is further configured to: obtain the chief complaint information of the user; perform word segmentation processing on the chief complaint information to obtain a plurality of phrases, and obtain a first estimated risk result matching the phrases according to a preset risk matching table; or perform semantic analysis on the chief complaint information to obtain a second estimated risk result; and obtain a path structure matching the first estimated risk result or the second estimated risk result from a preset path table.

[0162] In one example, the input by the user based on the terminal device includes the chief complaint information. The path matching module 1402 is further configured to: obtain the chief complaint information of the user; perform word segmentation processing on the chief complaint information to obtain a plurality of phrases, and obtain a first determined risk result matching the phrases according to a preset risk matching table; or perform semantic analysis on the chief complaint information to obtain a second determined risk result; present the first determined risk result or the second determined risk result to the user; receive a selection result of the user for the first determined risk result or the second determined risk result; and obtain a path structure matching the selection result from a preset path table.

[0163] In one example, the content-based node is associated with question options based on the current event to be answered by the user. The feedback information of the user based on the front-end display data includes the question results of the user for the question options. The evaluation module 1405 is further configured to: obtain a question result set composed of the question results; match the question result set with a cross-chain evaluation set in a preset event evaluation table to obtain a first evaluation result set, where the cross-chain evaluation set includes question options associated with nodes from multiple path structures; match the question result set with an in-chain evaluation set of the preset event evaluation table to obtain a second evaluation result set, where the in-chain evaluation set includes question options associated with nodes from the same path structure; obtain the union of the first evaluation result set and the second evaluation result set, and sort them according to the weights in the preset event evaluation table, and use the risk rating corresponding to the evaluation result with the highest weight as the first aid evaluation result of the current event.
