Description

Technical Field

[0001] This invention relates to the field of emergency medical technology, and more specifically, to an intelligent injury card device and its identification system. Background Technology

[0002] In emergency situations, the rapid and accurate acquisition of information on the injured location and severity of injuries is crucial for treatment decisions and evacuation scheduling. Chinese Patent CN120501394A discloses a triage wristband for patient triage, which uses a touchscreen display and voice recognition module to input injury information. The wristband is equipped with a blood pressure sensor, heart rate sensor, and temperature sensor. Medical personnel can input patient information and status via voice input, and the injury level is indicated by an LED strip surrounding the touchscreen display. Chinese Patent CN116504371A discloses an electronic injury ticket emergency system and method, including a ticket input module, a communication module, a central cloud module, and an edge cloud module. The ticket input module is used to input basic emergency information and corresponding preset RFID codes, while the central cloud module performs patient classification and route planning based on the basic emergency information.

[0003] All of the existing solutions mentioned above suffer from the drawback of requiring separate operations for injury location and injury severity determination. While CN120501394A supports voice input, location marking requires selection via a touchscreen display, and severity determination relies on voice description or additional menu interactions. Voice recognition reliability is limited in noisy environments, and the number of interaction steps is not reduced. Although CN116504371A achieves electronic management and remote transmission of injury certificates, basic emergency information still needs to be entered item by item through the injury certificate entry module; injury location and severity cannot be collected simultaneously in a single operation. Overall, under emergency conditions involving protective gloves, high stress, and frequent switching of vision, the separation of injury location and severity determination in existing solutions leads to numerous interaction steps, insufficient operational continuity, and a high risk of operational errors or interruptions in information collection. Therefore, an intelligent injury card device and its identification system are proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an intelligent injury card device and its identification system to solve the problem that the location of the injured part and the determination of the injury level need to be separated in the existing emergency injury marking scheme, which leads to many interactive steps, inconvenience in operation in the emergency environment and easy marking deviation.

[0005] To achieve the above objectives, the present invention provides an intelligent injury card device and its identification system, which is used to achieve single-touch integrated marking of injury location and injury level in an emergency environment, and to aggregate injury data to the rear medical rescue and command system.

[0006] A smart injury card device, shaped like a flat, round timer or name tag, includes a housing, a touch screen, a sensor module, a processor, a wireless communication module, a vibration module, and a switching button.

[0007] The touchscreen, located on the front of the casing without secondary pages, displays a simplified image of the human body, including multiple anatomical regions such as the head, torso, and limbs, as well as heart rate and pulse oximetry values. The sensor module, integrating a heart rate sensor and a pulse oximetry sensor, is located on the back of the casing, which also features Velcro straps. A switching button, located on the side of the casing, allows switching between displaying multiple built-in standard injury assessment cards. The device supports external NFC for writing patient identification information and assessment protocols.

[0008] The processor is configured to perform the following procedures: In response to a single touch operation on an anatomical region of the simplified human body image, the touch location and touch duration are obtained. Touch pressure value and contact area value ; The injured anatomical region is determined based on the touch location; based on , , The injury severity level is determined by comparing the results with the corresponding preset thresholds. Injury severity levels include minor injury, serious injury, and critical injury. Thus, the dual tasks of location and severity determination are completed in the parameter analysis of a single touch action, without requiring emergency personnel to make additional selections or switch menus. During the duration of a single touch operation, the color displayed in the anatomical region gradually changes from an initial color to the target color corresponding to the determined injury level: green for minor injuries, yellow for serious injuries, and red for critical injuries. The time required for this gradual change increases sequentially for minor, serious, and critical injuries. Emergency responders observe the color change during chest compressions. When the color reaches the desired level, they release the pressure, and the processor locks the current displayed color as the injury level marker and generates an injury record. The difference in the gradual change completion time between different levels provides rapid identification for common minor injuries, while allowing more time for observation and assessment of serious and critical injuries.

[0009] Furthermore, the processor... , , The comparison criteria are as follows: Will Compared with the preset first duration threshold Second duration threshold Compare; Will With the preset first pressure threshold Second pressure threshold Compare; Will With the preset first area threshold Second area threshold Compare.

[0010] when , , When any parameter reaches a higher threshold range, the injury level is adjusted to a higher level. This rule utilizes the positive correlation that the parameters usually have in actual operation, and allows for tolerance of individual parameter deviations caused by wearing protective gloves or operational stress, thus avoiding the underestimation of injury due to a single parameter not reaching the threshold.

[0011] Furthermore, the processor is configured to extract touch dynamic features during the duration of a single touch operation, including pressure change rate, area change rate, maximum pressure, maximum area, and center point offset. These dynamic features reflect the urgency of the press and the micro-drift of the finger from different dimensions.

[0012] The processor calculates a weighted sum of the features to obtain a predicted score, and determines the predicted injury level based on the predicted score, thereby inferring the possible severity of the injury in advance during the touch process.

[0013] The starting color of the color gradient is adjusted according to the estimated injury level: When the estimated injury level is serious or critical, the starting color is directly set to the color corresponding to serious injury. The gradient skips the color stage corresponding to minor injury, and the color changes to the tone direction of serious or critical injury more quickly, so that emergency personnel can obtain visual cues corresponding to the severity of the injury in the early stages of chest compressions.

[0014] Furthermore, the processor is also equipped with an independent fatality detection mechanism.

[0015] If two heavy-pressure long-press touch operations are detected on the target anatomical region within a preset time window, and the vital signs data collected by the sensor module within the time window meet the preset fatal injury conditions, then the injury level is determined to be fatal.

[0016] The heavy pressure long press touch operation refers to Reaching the preset pressure threshold and Touch operations that reach a preset duration threshold.

[0017] The preset fatal injury conditions are heart rate below the heart rate threshold or blood oxygen saturation below the blood oxygen threshold, which respectively characterize the degree of criticality of vital signs from two dimensions: heart rate and blood oxygen.

[0018] By repeatedly verifying the actions performed by the operator and the objective physiological indicators of the injured person, the marking of fatal injuries has higher reliability. When a fatal injury is determined, the processor will forcibly lock the corresponding anatomical section display color to black, overriding any previously determined injury level.

[0019] Furthermore, after locking the injury level, the processor initiates a correction window. If, within this window, a touch operation performed on the same anatomical region is detected again and its duration exceeds a correction duration threshold, the locked injury level is downgraded by one level. The downgraded injury level is not lower than that of a minor injury. First aid personnel can quickly correct the level within a limited time if they find the marker to be too high, but the correction operation is not applicable to fatal injury markers.

[0020] While locking onto the injury level, the processor controls the vibration module to generate a vibration pattern corresponding to that level. Different injury levels correspond to vibration sequences with varying numbers, widths, or intervals of pulses, allowing emergency responders to perceive and mark the results through touch without needing to look at the screen.

[0021] Furthermore, after the injury information is filled in, the processor's built-in AI analysis module automatically provides treatment plans based on the anatomical divisions and injury levels in the injury record, and uploads the injury record and material requirements to the medical rescue and command system via the wireless communication module.

[0022] Furthermore, multiple smart injury card devices and a medical rescue and command system constitute a smart injury recognition system.

[0023] Each smart injury card device has a built-in satellite positioning function, which displays its own location, the location of the nearest rescue point, and the real-time location and estimated arrival time of drone medical supplies and rescue vehicles.

[0024] Each smart injury card device uploads injury records to the medical rescue and command system via a wireless communication module, forming a centralized aggregation of injury data from multiple devices. Based on the aggregated injury records, the medical rescue and command system generates an injury situation map, graphically presenting the distribution of the injured and the severity of their injuries. It also coordinates rescue forces and medical supplies with a resource reserve database, prioritizing the deployment of rescue resources to areas with densely populated and severely injured individuals.

[0025] Furthermore, the various smart injury card devices form a self-organizing network via wireless communication modules, exchanging their locked injury records in environments without public network coverage. The self-organizing network elects one device as a gateway card, which aggregates all injury records within the network and uploads them uniformly to the medical rescue and command system, reducing the number of devices directly communicating with the command system and lowering the communication load.

[0026] The gateway card will also generate a local injury situation map from the aggregated injury records and send the local injury situation map to the medical rescue and command system.

[0027] The local casualty situation map is marked with the locations of unmarked potential casualties and areas of concentrated supply demand. The locations of potential casualties are inferred from the distribution density gradient of marked casualties, and the areas of concentrated supply demand are calculated based on the injury severity-weighted density, providing the rear command system with a reference for casualty distribution prediction and supply delivery.

[0028] The technical effects and advantages of this invention are as follows: First, in the intelligent injury card device provided by this invention, the processor acquires the touch duration T, touch pressure value F, and contact area value A of a single touch operation. It compares T with a preset first duration threshold and a preset second duration threshold, compares F with a preset first pressure threshold and a preset second pressure threshold, and compares A with a preset first area threshold and a preset second area threshold. Based on the comparison results of each parameter, it comprehensively determines whether the injury is minor, serious, or critical. This method integrates the location of the injured anatomical region and the determination of the injury level into the parameter analysis process of a single touch action. Emergency responders can perform a single press operation on the corresponding region on a simplified human image, allowing the processor to simultaneously complete both the location and level determination, thus reducing the operational burden caused by multi-step interactions.

[0029] Second, during the touch operation, the processor drives the display color of the corresponding anatomical region to continuously change from the initial color according to a non-uniform gradient duration. The gradient completion time is d1 for minor injuries, d2 for serious injuries, and d3 for critical injuries, satisfying d1 < d2 < d3. Emergency responders can observe the color change during compression. When the color reaches the desired level, the processor locks the current display color as the injury level marker. By setting the non-uniform gradient duration, common minor injury markers can be quickly confirmed, while serious and critical injury markers have more time for observation and confirmation. Combined with the vibration module generating tactile feedback with differentiated vibration patterns corresponding to the injury level, this helps emergency responders complete marker confirmation without taking their eyes off the injured person.

[0030] Third, regarding the determination of fatal injuries, the processor detects two heavy-press touch operations on the target anatomical region within a preset time window. Simultaneously, the sensor module collects vital sign data such as heart rate or blood oxygen saturation. When both the touch operation condition and the vital sign condition are met, it is determined to be a fatal injury, and the corresponding anatomical region is forcibly locked in black. This mechanism, through operator-initiated marking and cross-verification with the patient's objective physiological data, helps improve the reliability of fatal injury marking. At the system level, multiple smart injury card devices form a self-organizing network through wireless communication modules. The gateway card uploads the aggregated injury records to the medical rescue and command system, generating an injury situation map marked with the locations of potential casualties and areas of concentrated material demand. This helps the rear command platform to promptly grasp the overall distribution of injuries and rationally allocate rescue resources. Attached Figure Description

[0033] The attached diagram is labeled as follows: 1. Housing; 2. Touchscreen; 3. Sensor module; 4. Processor; 5. Wireless communication module; 6. Vibration module; 7. Switch button; Detailed Implementation

[0034] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1 As attached Figures 1 to 6 The device shown is an intelligent injury card device and its identification system, which is used to quickly mark the injury location and severity of the injured person in an emergency environment, and to collect the injury data to the rear medical rescue and command system for unified dispatch.

[0036] The intelligent injury card device includes a casing 1, a touchscreen 2, a sensor module 3, a processor 4, a wireless communication module 5, a vibration module 6, and a switching button 7. The casing 1 is in the shape of a flat, round timer or a name tag. The touchscreen 2 is located on the front of the casing 1 and has no secondary pages. After powering on, it displays a simplified human image, along with heart rate and pulse oximetry values. The simplified human image is divided into six anatomical regions: head, torso, left upper limb, right upper limb, left lower limb, and right lower limb. Each region corresponds to a preset coordinate range on the touchscreen 2. The sensor module 3 is located on the back of the casing 1 and integrates a heart rate sensor and a pulse oximetry sensor. The heart rate sensor outputs the heart rate value. The blood oxygen sensor outputs blood oxygen saturation values. The back of the outer casing 1 also features Velcro for securing the device to the injured person's body and ensuring the sensor module 3 fits snugly against the skin. The wireless communication module 5 integrates a LoRa communication unit and a BeiDou short message communication unit. The vibration module 6 is a linear motor. A switch button 7, located on the side of the outer casing 1, is used to switch the display of the built-in standard injury assessment card. The device supports external NFC writing, allowing the writing of the injured person's identification information and assessment protocols.

[0037] After the emergency personnel secured the device to the injured person's body, sensor module 3 started continuously collecting heart rate data. Blood oxygen saturation value Writes to the circular buffer in the processor 4's memory at a fixed frequency. The device's built-in satellite positioning unit acquires the current location information in real time, and the touch screen 2 displays its own location, the location of the nearest rescue point, and the real-time location and estimated arrival time of the drone medical supplies and rescue vehicle.

[0038] Regarding injury marking, when emergency personnel perform triage, they perform a single touch operation on the simplified human image to mark the injured anatomical region. In response to this touch operation, processor 4 synchronously reads the touch position coordinates and touch duration from the touchscreen 2's driving circuitry. Touch pressure value and contact area value .in, The timing starts at the sampling moment when the contact area changes from zero to non-zero, and ends at the sampling moment when the contact area returns to zero. It is obtained from the pressure sensing layer of the touch screen 2, or by equivalent conversion of the contact area; It is calculated from the contact point distribution reported by the capacitive touch array.

[0039] After obtaining the above parameters, processor 4 first performs anatomical partition localization, comparing the coordinates of the touch position with the coordinate range of each anatomical partition to determine the injured anatomical partition. If the coordinates fall on the boundary line between two partitions, the partitions are selected according to the preset priority order of trunk over head, head over upper limbs, and upper limbs over lower limbs. The left and right upper limbs have the same priority, and the left and right lower limbs have the same priority.

[0040] Processor 4 internal memory sometimes has a long threshold and ,satisfy ; pressure threshold and ,satisfy ; Area threshold and ,satisfy .

[0041] Processor 4 will , , The severity of the injury is determined by comparing the injury with the corresponding threshold.

[0042] Specifically, processor 4 will , , The comparison results are converted into grade values. The conversion rule is as follows: when the parameter value is less than the first threshold, the grade value is 0; when it reaches the first threshold but is less than the second threshold, the grade value is 1; and when it reaches the second threshold, the grade value is 2. After obtaining the three grade values, processor 4 takes the maximum value as the comprehensive grade value. When the comprehensive grade value is 0, it is judged as a minor injury; when it is 1, it is judged as a serious injury; and when it is 2, it is judged as a critical injury. This rule ensures that as long as one of the three parameters reaches a higher grade, the final judgment result will lean towards the higher grade, avoiding the misjudgment of a serious injury as a minor injury due to wearing protective gloves or operational tension.

[0043] In one example, the emergency responder applied significant pressure to specific areas of the torso and held the position for a period of time. achieve , achieve , achieve All three severity levels are 1, indicating a serious injury. In another example, the emergency responder performed chest compressions for a short duration but with great force. Not achieved , achieve , achieve In one example, the three levels were 0, 2, and 2, with a maximum value of 2, indicating a critical injury. In another example, the emergency responder lightly touched the skin and quickly released it; none of the three parameters reached their respective first thresholds, and the level values ​​were all 0, indicating a minor injury.

[0044] Once the injury severity is determined, processor 4 drives the display color of the anatomical region to continuously gradient from grayish-white to the target color during the duration of the touch operation. Minor injuries correspond to green, severe injuries to yellow, and critical injuries to red. The gradient is achieved through RGB three-channel linear interpolation. Processor 4 updates the display color values ​​at a fixed refresh rate and calculates an intermediate color value between grayish-white and the target color based on the proportion of the currently elapsed touch duration to the gradient completion time.

[0045] The time it takes to complete the gradual change corresponds one-to-one with the injury level; minor injury is... Seriously injured Critically injured ,satisfy As an alternative to non-uniform time scheduling, Pick 1.5 times, Pick Twice as a possible alternative, , , Determined according to exponential relationships, Pick 2 times, Pick Four times longer. The non-uniform gradual change in duration allows for rapid marking of common minor injuries, while providing more time for observation and confirmation of marking of serious and critical injuries.

[0046] Emergency responders continuously observe the color changes of the anatomical region during chest compressions. As compression time progresses, the color first transitions from grayish-white to the green zone, then gradually to the yellow zone with continued compression, and finally to the red zone with continued compression. When the color reaches the level corresponding to the desired injury severity, the emergency responder lifts their finger. Processor 4 detects... Once the touch threshold is lowered to below the preset threshold, the operation is considered complete. The current display color is locked as the injury level marker, and an injury record is generated. The injury record includes the injury anatomical partition identifier and the injury level identifier.

[0047] As an alternative implementation, during the duration of the touch operation, processor 4 also synchronously extracts touch dynamic features and adjusts the starting color of the color gradient accordingly. This adjustment does not change the underlying... , , The final injury level only affects the initial color during the gradation process.

[0048] Processor 4 reads the current touch pressure value, contact area value, and touch center point coordinates at a fixed sampling period, using the data at the start of the touch as a reference.

[0049] Processor 4 extracts five dynamic features: Pressure change rate It is obtained by dividing the difference between two adjacent pressure values ​​by the sampling period; Area change rate Similarly, calculate the maximum pressure. It compares and updates the value with the recorded maximum value at each sampling time; Maximum area The update method is the same; center point offset The distance is obtained by subtracting the coordinates of the starting center point from the coordinates of the current center point and then taking the Euclidean distance.

[0050] Processor 4 calculates the predicted score by weighted summation of the five feature values. The calculation formula is: in to These are the preset weighting coefficients.

[0051] Processor 4 internal memory has an estimated tier threshold. and ,satisfy .when The initial assessment was that the injury was minor. The initial assessment was that the injury was serious. The initial assessment was that the injury was critical.

[0052] Processor 4 determines the starting color based on the estimated injury level. The starting color is grayish-white for a minor injury, light yellow for a serious injury, and orange for a critical injury. When the injury is estimated to be serious or critical, processor 4 skips the color phase, directly setting the starting color value to the yellow corresponding to a serious injury, with the gradient transitioning from yellow to red without passing through green. When the injury is estimated to be minor, the gradient still starts from grayish-white, sequentially passing through green, yellow, and red.

[0053] It should be noted that the above adjustments only apply to the display effect of the gradient process. At the end of the touch operation, the injury level ultimately locked by processor 4 remains unchanged. , , The overall assessment result shall prevail. If the estimated injury level is higher than the overall assessment injury level, the color displayed at the moment of release will drop from the hue corresponding to the higher level to the color corresponding to the lower level; if the estimated level is equal to or lower than the overall assessment level, the color displayed at the moment of release will be consistent with the color of the gradient endpoint.

[0054] In terms of fatal injury determination, the processor 4 is equipped with an independent fatal injury determination mechanism, which is completed by two independent determination links: touch operation conditions and vital signs conditions.

[0055] Processor 4 continuously monitors touch events. When a touch operation is detected that satisfies... and At that time, processor 4 starts the first preset time window and the second preset time window, and the start time and duration of the two windows are the same. The operation of this triggered window does not participate in the counting within the window.

[0056] Within a first preset time window, processor 4 monitors subsequent touch operations occurring on the target anatomical region. The condition for a fatal touch operation is: within the window, two more touch operations that meet the criteria occur on that region. and The touch operation must be performed within the same anatomical region. If the window times out and does not detect two operations that meet the requirements, the window closes, and processor 4 resumes monitoring for the next heavy press operation.

[0057] Meanwhile, processor 4 continuously reads vital sign data collected by sensor module 3 within a second preset time window. The vital sign criteria for a fatal injury are that at least one of the following is met: heart rate value... Blood oxygen saturation value below heart rate threshold The injury is below the blood oxygen threshold. When both the touch operation condition and the vital signs condition are met simultaneously within the window, processor 4 determines it to be a fatal injury. Processor 4 forcibly locks the display color of the corresponding anatomical section to black, overriding any previously determined injury level, and immediately sends the fatal injury record via wireless communication module 5. Once the fatal injury mark is locked, it does not respond to correction operations.

[0058] In one example, emergency responders find a victim with severe torso injuries and who is unresponsive. They perform a long press on the torso section, triggering a time window in processor 4. Within this window, the emergency responders perform two more long presses, and simultaneously, sensor module 3 detects that the victim's heart rate has dropped below a certain threshold. The fatal injury is then confirmed, and the torso section is marked in black.

[0059] Regarding injury level correction, processor 4 initiates a correction window when the injury level is locked, and the window duration is less than [missing information]. Within the correction window, if a touch operation is detected again on the same anatomical region, and the duration of this touch operation exceeds the correction duration threshold, the locked injury level will be downgraded by one level. Critical injury will be downgraded to serious injury, serious injury to minor injury, and minor injury will remain unchanged. After correction, processor 4 updates the injury record and display color, and immediately transmits the corrected injury record via wireless communication module 5. The correction window closes after timeout; fatal injuries are not subject to correction.

[0060] Regarding vibration feedback, after locking onto the injury level, processor 4 drives vibration module 6 to generate the corresponding vibration mode. The vibration mode is as follows: Minor injuries correspond to a single pulse with a pulse width of 100ms; serious injuries correspond to two pulses with a pulse width of 150ms and an interval of 100ms between the two pulses. Critical injuries correspond to a single pulse with a pulse width of 500ms; fatal injuries correspond to three pulses with a pulse width of 200ms and an interval of 100ms between adjacent pulses.

[0061] If a correction operation is triggered during vibration execution, the processor 4 will take different actions depending on whether the vibration has ended when the correction occurs: if the vibration has not ended when the correction occurs, the current vibration will be interrupted and the vibration will be restarted in the vibration mode corresponding to the corrected level; if the vibration has ended when the correction occurs, a new vibration will be started directly in the vibration mode corresponding to the corrected level.

[0062] Regarding AI analysis and treatment plans, after the injury report is completed, the AI ​​analysis module built into processor 4 automatically generates corresponding treatment plan suggestions based on the anatomical divisions and injury severity levels in the injury record, and displays them via touchscreen 2. Processor 4 also uploads the injury record and material requirements to the medical rescue and command system via wireless communication module 5.

[0063] Regarding the standard injury assessment cards, emergency responders press the switch button 7 on the side, and the touchscreen 2 sequentially switches between displaying the standardized injury assessment card, the concussion injury assessment card, and the spinal cord injury assessment card. Each assessment card is presented in the form of a checklist. After the emergency responder confirms each item, the assessment results are automatically appended to the injury label of the corresponding anatomical region.

[0064] At the system level, multiple smart injury card devices and a medical rescue and command system constitute an intelligent injury recognition system. Each device obtains its current location in real time through its built-in satellite positioning unit, and the touch screen 2 displays its own location, the location of the nearest rescue point, and the real-time location and estimated arrival time of drone medical supplies and rescue vehicles.

[0065] After generating injury records, each device sends data packets via wireless communication module 5. These packets contain the injured person's identification, anatomical zoning, injury severity, and satellite positioning coordinates. The devices form a self-organizing network via LoRa communication units, periodically broadcasting their identification and remaining battery level. The device with the highest battery level is nominated as the gateway card; in case of a tie, the device with the larger identification hash value is selected. Each device periodically compares its battery level; if the gateway card's battery level is lower than other devices or it fails to broadcast for several consecutive periods, a new gateway card is nominated.

[0066] The gateway card aggregates injury records from all devices within the network, deduplicates them according to the injured person's identity, and merges them into a summary message. The gateway card establishes a relative coordinate system with its own coordinates as the reference origin, transforms the coordinates of each injured person, and marks them on a local injury situation map, with the color of the marked points corresponding to the injury level. After weighting the coordinates of each injured person according to their injury level, kernel density estimation is performed, and areas with density exceeding a threshold are marked as areas with concentrated material demand. Starting from the marked injured person's location where the density exceeds a preset threshold, the system extends along the density gradient direction by a fixed step size, accumulating a preset total extension distance. Unmarked locations along the extension path are marked with dashed outlines as potential injured person locations.

[0067] The gateway card will send the summary message and local injury situation map to the medical rescue and command system via BeiDou short message. After receiving the message, the medical rescue and command system will spatially register and stitch the multiple local situation maps according to the positioning coordinates of each gateway card. The overlapping area will be selected based on the injury level with the highest severity, generating a global injury situation map. The system will then combine this map with the material reserve database to generate a dispatch plan, specifying the delivery targets, quantities, and priorities for each rescue node.

[0068] The following two complete operational examples demonstrate the process of first responders using this device to mark injuries.

[0069] In the first example, emergency responders secured the device to the injured person's chest, and sensor module 3 began collecting vital signs. The emergency responders found a shrapnel wound in the injured person's left lower limb, with significant bleeding, but the person was conscious. They applied pressure to specific areas of the left lower limb on a simplified human image, applying considerable force and maintaining the pressure for a certain period. Processor 4 read... , , parameter, achieve , achieve , achieve The three severity levels are 1, 2, and 1, respectively, with a combined severity level of 2, classifying the injury as critical. During the compression process, processor 4 simultaneously extracts dynamic features and calculates the estimated score. ,get The injury was initially assessed as critical, with the initial color set to orange, skipping the green stage. Emergency responders observed the left lower limb area rapidly transitioning from orange to yellow and then to red; upon confirmation, they released their grip. Processor 4 locked onto the red area, generating an injury record, and vibration module 6 produced a 500ms long vibration to confirm the critical injury. No corrections were made within the correction window; processor 4's built-in AI analysis automatically provided a treatment plan. The injury record and material requirements were transmitted to the self-organizing network via wireless communication module 5 and ultimately uploaded to the medical rescue and command system.

[0070] In the second example, emergency responders examined the same patient's right upper limb and found only abrasions. They lightly touched the affected area and quickly released it. Processor 4 reads... , , None of the injuries met the first threshold, and all three level values ​​were 0, classifying the injury as minor. During the compression process, processor 4 simultaneously extracted dynamic features and calculated the estimated score. ,get The estimated injury level was also minor, with the color starting from grayish-white. Due to the extremely short compression time, the emergency responders released their hands before the gradual change was complete. Processor 4 locked the current display color to green, and vibration module 6 generated a single 100ms pulse to confirm the minor injury. The injury record was also uploaded to the command system via a self-organizing network. The patient had two injury records simultaneously: a critical injury to the left lower limb and a minor injury to the right upper limb. The command system marked the two injured areas of the patient in red and green respectively on the situation map.
