Injury assessment and treatment guidance system suitable for on-site emergency care Technical Field
[0001] This invention relates to the field of medical emergency and survival support technology, and in particular to a system for injury assessment and treatment guidance applicable to on-site emergency care. Background Technology
[0002] Traditional casualty care requires professional medical personnel to arrive at the scene to assess the injuries. However, when the location of the casualties is far from the treatment site or the road conditions are complex, medical personnel cannot arrive in time, and the injured cannot be quickly transported to the treatment site. When the scale of the casualties is large and the injuries change rapidly, it is impossible to anticipate the severity and changes in the injuries of a large number of casualties in advance. These situations delay the "golden time" for casualty care and fail to guarantee the timeliness of treatment. In sudden accidents, disaster scenes, or battlefield environments, the number of casualties is large and the injuries are complex, and professional medical personnel often cannot arrive at the scene immediately. Traditional emergency rescue methods rely on human judgment and experience, which has the following problems: inability to monitor the vital signs of the casualties in real time and continuously; strong subjectivity in injury assessment, prone to misjudgment or omission; lack of treatment knowledge and skills among non-professionals; and inability to prioritize multiple casualties. Therefore, there is an urgent need for an intelligent system that can automatically assess injuries, provide treatment guidance, and support the management of multiple casualties to improve emergency rescue efficiency and survival rates. Summary of the Invention
[0003] The purpose of this invention is to provide an injury assessment and treatment guidance system suitable for on-site emergency care, solving problems such as inaccurate injury assessment, untimely treatment, and the inability of non-professionals to effectively participate in on-site rescue in existing technologies. By analyzing changes in the vital signs of the injured, the system can pre-judge the severity and changes in the injuries, and, when self-rescue and mutual-rescue conditions are available, provide treatment guidance for typical injuries to on-site non-professional medical personnel.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A system for injury assessment and treatment guidance applicable to on-site emergency care, comprising: a vital signs monitoring module for real-time monitoring and collection of vital signs parameters such as heart rate, respiratory rate, body temperature, blood pressure, and blood oxygen saturation; an indicator parameter presentation module for displaying vital signs parameters and receiving subjective symptom information input by the user; an injury assessment module for processing and analyzing the vital signs parameters and subjective symptom information to assess the severity and trend of the injury; and a treatment method guidance module for providing corresponding text and video treatment guidance based on the injury assessment results from the injury assessment module.
[0005] Furthermore, the vital signs monitoring module includes: a heart rate and respiratory rate sensing unit for collecting heart rate and respiratory rate parameters; a body temperature sensing unit for collecting body temperature parameters; a blood pressure and blood oxygen sensing unit for non-invasive measurement of blood pressure and blood oxygen saturation parameters; and a communication unit for transmitting the collected vital signs parameters to the indicator parameter presentation module.

[0007] Furthermore, the injury assessment module includes: a data processing unit, used to integrate and analyze the vital signs parameters and subjective symptoms of the human body, and to determine the injury based on preset injury grading rules; and an injury result presentation unit, used to present the severity grading of the injury and the changes in the injury.
[0008] Furthermore, the injury grading rules divide injuries into four levels: Level 1: minor injury; Level 2: moderate injury; Level 3: severe injury; Level 4: critical injury.
[0009] Furthermore, the treatment method guidance module includes: a text-based treatment method guidance unit with a built-in treatment knowledge base and rule base, supporting the retrieval of corresponding treatment steps according to the type of injury; a video-based treatment method guidance unit, providing operation demonstration videos of hemostasis, bandaging, ventilation, immobilization, transportation, and cardiopulmonary resuscitation; furthermore, the treatment method guidance module also includes: an intelligent recommendation unit, used to automatically match and recommend priority treatment measures based on the injury level and type.
[0010] Furthermore, it also includes: a data storage and retrieval module for storing historical vital sign data, injury assessment records, and treatment operation records; and a remote transmission module for transmitting injury data to a remote medical platform or a rescuer's terminal in real time.
[0011] Furthermore, the system also supports a priority ranking function for multiple injured persons, automatically generating treatment order suggestions based on the severity of injuries.
[0012] The beneficial effects of this invention are: This invention can assess and determine the severity and changes in the condition of an injured person immediately after injury and before professional medical personnel arrive at the scene, providing a reference for the order and methods of treatment after medical personnel arrive at the scene, and guiding non-professional medical personnel at the scene to provide timely and concise treatment to injured persons who need pre-treatment.

[0013] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the accompanying drawings used in the description of the embodiments or the prior art are briefly introduced below.
[0014] Figure 1 is a schematic diagram of the injury assessment and treatment guidance system applicable to on-site emergency care according to the present invention. Detailed Implementation
[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0016] Example 1, as shown in Figure 1, describes an injury assessment and treatment guidance system for on-site emergency care according to the present invention. The system includes: a vital signs monitoring module for real-time monitoring and collection of vital signs parameters such as heart rate, respiratory rate, body temperature, blood pressure, and blood oxygen saturation; an indicator parameter presentation module for displaying vital signs parameters and receiving subjective symptom information input by the user; an injury assessment module for processing and analyzing the vital signs parameters and subjective symptom information to assess the severity and trend of the injury; and a treatment method guidance module for providing corresponding text and video treatment guidance based on the injury assessment results from the injury assessment module.
[0017] Furthermore, the vital signs monitoring module includes: a heart rate and respiratory rate sensing unit for collecting heart rate and respiratory rate parameters; a body temperature sensing unit for collecting body temperature parameters; a blood pressure and blood oxygen sensing unit for non-invasive measurement of blood pressure and blood oxygen saturation parameters; and a communication unit for transmitting the collected vital signs parameters to the indicator parameter presentation module.
[0018] Furthermore, the indicator parameter presentation module includes: a vital sign parameter presentation unit, used to display in real time the various vital sign parameters collected by the vital sign monitoring module; and a subjective consciousness state input unit, used to input the user's subjective symptom information; wherein the user is an injured person or a rescuer; and the subjective symptom information includes the human body's subjective consciousness state, pain location, and pain level.
[0019] Furthermore, the injury assessment module includes a data processing unit, used to perform fusion analysis on the human body's vital signs parameters and subjective symptom information, and to determine the injury based on preset injury grading rules; wherein the analysis includes: analysis of the severity of the injury.
[0020] The injury outcome presentation unit is used to present the severity level of the injury and the changes in the injury.
[0021] Furthermore, the injury grading rules divide injuries into four levels: Level 1: minor injury; Level 2: moderate injury; Level 3: severe injury; Level 4: critical injury.
[0022] Furthermore, the treatment method guidance module includes: a text-based treatment method guidance unit with a built-in treatment knowledge base and rule base, which supports retrieving corresponding treatment steps according to the type of injury; and a video-based treatment method guidance unit, which provides operation demonstration videos of hemostasis, bandaging, ventilation, immobilization, transportation, and cardiopulmonary resuscitation.
[0023] Furthermore, the treatment method guidance module also includes an intelligent recommendation unit, which automatically matches and recommends priority treatment measures based on the severity and type of injury.
[0024] Furthermore, the injury assessment and treatment guidance system for on-site emergency care of the present invention also includes: a data storage and retrieval module for storing historical vital sign data, injury assessment records and treatment operation records; and a remote transmission module for transmitting injury data to a remote medical platform or a rescuer's terminal in real time.
[0025] Furthermore, the injury assessment and treatment guidance system for on-site emergency care of the present invention also supports a multi-injury priority ranking function, automatically generating treatment order suggestions based on the injury level.
[0026] Based on vital signs parameters (heart rate, respiratory rate, body temperature, blood pressure, blood oxygen saturation) and subjective symptoms (subjective state of consciousness, location of pain, and intensity of pain), a scoring system is used to determine the severity of injury. Each vital sign parameter is assigned a score based on the degree to which its value deviates from the normal range, and subjective symptoms are assigned additional points based on their severity. The total score is calculated as follows: Total Score = Σ(Vital Sign Parameter Score) + Σ(Subjective Symptom Score). The injury severity grading rules are as follows: a total score of 0-3 points indicates a Level 1 minor injury, 4-6 points indicates a Level 2 moderate injury, 7-9 points indicates a Level 3 severe injury, and 10 points or above indicates a Level 4 critical injury. The normal range and scoring criteria for vital signs parameters are as follows: Heart rate: Normal range 60-100 bpm, below 60 or above 100 bpm, 1 point is awarded; severe abnormalities (such as below 50 or above 120 bpm) award 2 points. Respiratory rate: Normal range 12-20 rpm, below 12 or above 20 rpm gets 1 point, severe abnormality (e.g. below 10 or above 30) gets 2 points; Body temperature: Normal range 36-37°C, below 36 or above 37°C gets 1 point, severe abnormality (e.g. below 35 or above 38) gets 2 points; Blood pressure: Normal range systolic blood pressure 90-140 mmHg, normal range diastolic blood pressure 60-90 mmHg, any parameter exceeding the range gets 1 point, severe abnormality (e.g. systolic blood pressure below 80 or above 160) gets 2 points; Blood oxygen saturation: Normal range 95-100%, below 95% gets 1 point, below 90% gets 2 points; Subjective symptom scoring criteria are as follows: Subjective consciousness: Awake gets 0 points, Confused (conscious but unclear state of consciousness) gets 1 point, Coma gets 2 points; Pain level: No pain gets 0 points, Mild pain gets 1 point, Moderate pain gets 2 points, Severe pain gets 3 points.
[0027] The severity of injury is displayed in the severity level display area of the injury result presentation unit.
[0028] Based on Example 1, Example 2's injury result presentation unit includes a level display area and a condition trend display area.
[0029] The data processing unit's analysis also includes assessing the trend of injury changes. This assessment is determined through a calculation method, specifically: collecting vital sign parameters over a continuous time series and calculating the rate of change for each parameter; the rate of change is calculated as: Rate of change = (Current value - Previous time point value) / Time interval; weighted summation of the rates of change yields a trend score: Trend score = Σ(Weight × Parameter rate of change); the weights are preset based on the importance of the parameters, for example, heart rate weight 0.3, respiratory rate weight 0.2, blood oxygen saturation weight 0.3, and blood pressure weight 0.2; a trend score greater than 0 indicates worsening injury, while a score less than 0 indicates improvement; a larger absolute value of the trend score indicates a faster change; the assessment of the injury trend can be displayed in a trend display area using charts to show parameter changes and trend scores.
[0030] Furthermore, the intelligent recommendation unit performs matching based on a rule engine. For example, when the injury level is level four, cardiopulmonary resuscitation and ventilation measures are recommended first, and when the injury level is level three, hemostasis and immobilization measures are recommended first.
[0031] Furthermore, the priority ranking method is as follows: sort by injury severity from high to low, and if the severity levels are the same, sort by the trend score of the condition from high to low (i.e., those that deteriorate faster are prioritized); the ranking algorithm is as follows: calculate a priority score for each injured person, priority score = injury severity coefficient × 10 + trend score, where the injury severity coefficient is 4 for level 4, 3 for level 3, 2 for level 2, and 1 for level 1, and then sort them in descending order of priority score.
[0032] Example 3, based on Example 1 or Example 2, involves the system being started, with each module connected via wireless communication (such as Bluetooth) or wired connection. The vital signs monitoring module is worn on the injured person's body to begin real-time monitoring of vital signs.
[0033] The indicator parameter presentation module is usually a mobile terminal (such as a tablet or smartphone) that displays vital sign parameters and provides an input interface.
[0034] Heart rate and respiratory rate sensing unit: This unit uses photoelectric sensors or electrodes to collect electrocardiogram (ECG) signals and calculates heart rate and respiratory rate using algorithms. For example, a peak detection algorithm is used to calculate heart rate, and respiratory rate is calculated based on changes in thoracic impedance. The algorithms and the methods used to collect ECG signals by photoelectric sensors or electrodes are common knowledge and will not be described in detail here.
[0035] Body temperature sensing unit: Uses a thermistor or infrared sensor to measure body surface temperature.
[0036] Blood pressure and oxygenation sensing unit: Blood pressure is measured non-invasively, and oxygen saturation is measured using a pulse oximeter.
[0037] Communication unit: The collected data is wirelessly transmitted to the indicator parameter presentation module via Bluetooth protocol at a frequency of once per second.
[0038] Vital signs parameter display unit: Receives and displays heart rate, respiratory rate, body temperature, blood pressure and blood oxygen saturation data in real time, presented in digital and waveform form.
[0039] Subjective Consciousness Input Unit: Provides a touch interface for users to input subjective symptoms, including consciousness state (select from drop-down menu: awake, confused, comatose), pain location (select from body atlas), and pain level (select from 0-3 points using a slider).
[0040] The text-based first aid instructions unit retrieves first aid steps from the knowledge base based on the severity and type of injury. For example, for a level 3 injury with bleeding, it displays text instructions such as "apply pressure to stop the bleeding and bandage the wound."
[0041] Treatment Method Video Guidance Unit: Plays corresponding operation demonstration videos, such as videos on hemostasis and bandaging.
[0042] Intelligent recommendation unit: Recommends priority measures based on a rule engine. For example, if the injury is level three and the trend is worsening, the recommendation is "immediately stop the bleeding and monitor vital signs".
[0043] Remote transmission module: Transmits injury data to the hospital platform in real time via 4G / 5G network for remote doctor guidance.
[0044] Prioritization of Multiple Injured Persons: When there are multiple injured persons, the system calculates a priority score for each. For example, Injured Person A has a level 3 injury (coefficient 3) and a trend score of 0.42, so their priority score is 3 × 10 + 0.42 = 30.42; Injured Person B has a level 2 injury (coefficient 2) and a trend score of -0.2, so their priority score is 2 × 10 - 0.2 = 19.8. The ranking result is that Injured Person A is prioritized over Injured Person B.
[0045] The invention is simulated and validated in a simulated field environment to ensure data accuracy and real-time performance. For example, using a simulated human body, the error in vital sign monitoring is verified to be less than 5%, and the consistency between injury assessment and manual assessment exceeds 90%.
[0046] The present invention provides an injury assessment and treatment guidance system for on-site emergency care, which addresses the problems of difficulty in timely perception of injuries and guarantee of timely treatment before professional rescuers arrive at the scene. It enables the immediate assessment and determination of the severity and changes in the injury of the injured, provides a reference for the sequence and methods of treatment implemented by rescuers after they arrive at the scene, and guides non-professional rescuers at the scene to provide timely and concise treatment to the injured who need pre-treatment.
[0047] Modules or units not described in detail in the above embodiments are well-known components, common structures or common means in this industry, and will not be described one by one here.
[0048] This invention is not limited to the above embodiments. Those skilled in the art can make equivalent substitutions or improvements to the sensor type, communication protocol, algorithm model, etc., without departing from the spirit of this invention, and all of these fall within the protection scope of this invention.
