Description

Technical Field

[0001] This invention relates to the field of medical emergency equipment technology, and in particular to an integrated multifunctional individual soldier's intelligent TCM emergency pen. Background Technology

[0002] Within the critical ten-minute window of emergency medical care in high-risk environments such as battlefields and disaster relief, emergency responders must quickly screen the wounded for vital signs and implement traditional Chinese medicine acupuncture point intervention. However, existing individual emergency medical equipment often equips thermometers, pupillary light pens, pulse therapy devices, and loose acupuncture needles separately. This highly fragmented functional module not only leads to cumbersome carrying and extremely slow response times on the battlefield, but also lacks a data loop between triage and intervention equipment, relying heavily on the rescuer's subjective experience for parameter conversion, making it difficult to guarantee the accuracy and scientific nature of emergency medical plans.

[0003] Furthermore, traditional manual acupuncture, under harsh conditions such as wearing tactical protective gloves or having limited visibility, is highly susceptible to loss of control during needle insertion due to distorted movements, and the use of loose needles poses a significant risk of contamination in the field. Simultaneously, existing purely electronic physiotherapy devices become completely inoperable when exposed to extreme cold, power outages, or damage, lacking a physical redundancy backup solution for extreme situations. Therefore, there is an urgent need in this field for a portable individual emergency terminal that can highly integrate vital sign screening and adaptive intervention functions, achieve one-click mode switching and objective data closed-loop, and balance aseptic rapid treatment with electromechanical fault tolerance, in order to address the technical pain points of existing equipment's fragmented functions and poor environmental adaptability. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] A multifunctional individual soldier's TCM intelligent first aid pen includes an integrated pen body and a multimodal vital sign sensing module installed on the integrated pen body. This module collects infrared body temperature data and pupil light reflection data, and performs triage and judgment based on the infrared body temperature data and pupil light reflection data to obtain injury assessment results.

[0007] The system status monitoring module acquires the system power supply status information of the built-in power supply and the hardware operation status of the microcontroller.

[0008] The control state machine module receives the injury assessment result, the infrared body temperature data, and the pupil light reflection data, and, in conjunction with the triage level in the injury assessment result, maps the infrared body temperature data and the pupil light reflection data to the target physiotherapy current amplitude and the target physiotherapy current frequency, respectively.

[0009] The multimodal intervention module, when the system power supply status information meets the power supply threshold and the hardware operation status word is a normal code, uses the target physiotherapy current amplitude and the target physiotherapy current frequency to drive the ring electrode to output a microcurrent pulse physiotherapy signal.

[0010] The mechanical acupuncture emergency module releases the electrical control constraint of the physical locking mechanism when the system power supply status information is lower than the power supply threshold or the hardware operation status word is an abnormal code, so that the system enters a purely physical ready state, allowing external mechanical input to drive the needle push rod to eject to the target needle insertion depth position, and allowing external torque to drive the needle storage and changing chamber to rotate step by step.

[0011] Furthermore, the multimodal vital sign sensing module includes an infrared signal processing unit, which acquires the original body temperature electrical signal collected by the infrared temperature probe deployed at the front end of the integrated pen body through a serial peripheral interface, performs noise reduction processing on the original body temperature electrical signal using a preset moving average filtering algorithm, and performs analog-to-digital conversion calculation on the noise-reduced original body temperature electrical signal to output the infrared body temperature data.

[0012] The body temperature risk assessment unit receives the infrared body temperature data and compares the infrared body temperature data with a preset low body temperature warning threshold. When the infrared body temperature data is lower than the low body temperature warning threshold, it generates low body temperature shock risk information and encapsulates the low body temperature shock risk information as the first part of the injury assessment result and transfers it to the control state machine module.

[0013] Furthermore, the multimodal vital sign perception module also includes: a pupil stimulation control unit, which generates a timing drive command with a specified frequency and waveform characteristics, controls the yellow pupil stimulation light source integrated at the front end to emit stimulation light waves according to a preset modulation frequency, and uses an image sensor to continuously collect image sequences of dynamic changes in the pupil area of ​​the injured person after being irradiated by the stimulation light waves.

[0014] The light reflection assessment unit receives the image sequence of dynamic changes in pupil area, calculates the pupil light reflection time delay and area contraction amplitude under the action of the stimulus light wave using an image recognition algorithm to obtain the pupil light reflection data, performs vector matching operation on the pupil light reflection data with a preset multi-level nervous system state norm matrix to determine the corresponding central nervous system state level and generates triage label information as the second part of the injury assessment result.

[0015] Furthermore, the control state machine module includes: a knob signal monitoring unit, which polls and monitors in real time the physical contact switching electrical signal triggered by the rotating knob located in the middle of the integrated pen body, and converts the physical contact switching electrical signal into a digital state transition condition.

[0016] The sequence control execution unit receives the digital state transition condition and switches the current system control state to the corresponding target working state. The target working state includes a pre-detection state and a pulse therapy state. The sequence control execution unit limits the target working state to support bidirectional free switching logic between the pre-detection state and the pulse therapy state to meet the parameter rollback adjustment requirements. When switching to the pulse therapy state for the first time, the unit issues a vital sign data read permission instruction to the internal memory.

[0017] Furthermore, the control state machine module also includes a parameter transfer and storage unit, which receives the infrared body temperature data, the pupil light reflection data, and the injury assessment result containing triage label information injected into the microcontroller's internal storage unit during the pre-examination state, and reads out and merges the three data to construct a vital sign vector to be mapped when a read permission command is received.

[0018] The mapping matrix calculation unit parses the triage label information from the vital sign vector to be mapped to obtain the corresponding dynamic weight coefficients. The infrared body temperature data is used as the first independent variable. Substitute the values ​​into the physical amplitude mapping algorithm to calculate the reference value and multiply it by the dynamic weighting coefficient. The target therapeutic current amplitude is obtained, and the pupillary light reflection data is used as the second independent variable. The target therapeutic current frequency encapsulation output is obtained by substituting it into the frequency mapping algorithm.

[0019] Furthermore, the multimodal intervention module includes an electrode impedance feedback unit, which reads the real-time contact impedance feedback value of the annular electrode when the system power supply status information meets the power supply threshold, and outputs a pulse enable control signal when it is determined that the annular electrode and the injured person's skin are in an effective contact closed-loop state based on the real-time contact impedance feedback value.

[0020] The microcurrent pulse modulation unit receives the target therapeutic current amplitude and the target therapeutic current frequency when it receives the pulse enable control signal. It uses the target therapeutic current amplitude to dynamically modulate the output voltage amplitude parameter of the underlying reference pulse signal, and uses the target therapeutic current frequency to dynamically modulate the output frequency parameter of the underlying reference pulse signal, thereby generating the modulated microcurrent pulse therapeutic signal to drive the output.

[0021] Furthermore, the system status monitoring module includes: a hardware status sampling unit, which periodically and at high speed samples the remaining power percentage data of the built-in power supply as the system power supply status information, and samples the underlying register status data of the microcontroller as the hardware operating status word. When the remaining power percentage data is lower than the power supply threshold or the underlying register status data shows the abnormal code, the system is determined to be in an abnormal state and outputs a low-level hardware cutoff signal.

[0022] The circuit electronic interlock unit receives the low-level hardware cut-off signal and, under the action of the internal hardware interlock control circuit, directly cuts off the power supply path between the multimodal vital sign sensing module and the multimodal intervention module. At the same time, it releases the electronic limit constraint on the physical locking mechanism and disengages from the locked state through the power-off unlocking solenoid valve mechanism.

[0023] Furthermore, the mechanical acupuncture emergency module includes a depth limit adjustment unit. After the physical locking mechanism releases the electronic control constraint, a three-position limit ratchet mechanism located at the tail of the integrated pen body is allowed to respond to external rotational physical operation to select the target needle insertion depth position. The target needle insertion depth position includes a 3mm limit groove, a 5mm limit groove, and an 8mm limit groove. During the process of the three-position limit ratchet mechanism rotating and engaging the corresponding groove, the built-in needle main spring is simultaneously compressed to deform and complete the ejection energy storage.

[0024] The physical trigger self-locking unit, after the built-in needle main spring has completed energy storage, responds to the mechanical pressing stroke operation of the tail physical trigger button to release the axial constraint structure, drives the ejector pin to instantly eject along the pen body axis, and performs one-way mechanical locking through the self-locking buckle when it moves to the physical limit end position.

[0025] Furthermore, the mechanical acupuncture emergency module also includes: a needle storage multi-slot arrangement unit, which uses multiple sets of independent sterile needle slots arranged in a ring to accommodate multiple disposable sterile acupuncture needles, and keeps the central rotation axis of the needle storage and replacement chamber parallel to the linear motion axis of the push rod in space.

[0026] The automatic needle changing positioning unit, after the physical locking mechanism releases the electrical control constraint, allows the outer wall of the needle storage and changing chamber to receive the externally applied tail-end turning and shifting torque, causing the needle storage and changing chamber to rotate at a fixed angle step around the central rotation axis. When the physical positions of two adjacent sets of sterile needle slots are switched, the elastic positioning pins arranged in a ring on the outer wall fall into the positioning holes of the slot, ensuring that the sterile needle slot currently in the working position coincides with the axis of the ejector pin.

[0027] Furthermore, it also includes an embedded interactive safety feedback module, which includes a physical lock safety control unit that captures in real time the sliding lock block position status level signal output by the independent physical anti-misoperation lock structure outside the pen body, and issues a hardware interrupt isolation command when the sliding lock block position status level signal indicates that it is in the locked position, forcibly cutting off the pulse current output control circuit of the multimodal intervention module, and blocking the downward travel of the physical trigger button so that the mechanical mechanism is in a locked shielded state.

[0028] The interactive multi-channel display unit reads the current device operating mode category data, the corresponding pulse intensity level data, and the system power supply status information output by the control state machine module, and drives the front-end embedded digital display screen to perform multi-channel digital synchronous real-time display.

[0029] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:

[0030] (1): This invention integrates a multimodal vital sign sensing module, a control state machine module, and a multimodal intervention module into a single pen body. Through data flow within the system, infrared body temperature data and pupillary light reflection data, after completing the initial vital sign acquisition, are directly mapped by the control state machine into the target physiotherapy current amplitude and target physiotherapy current frequency. This dual integration of structure and algorithm changes the traditional situation of fragmented functions and disconnected assessment and intervention in individual first aid equipment, enabling rescuers to complete automated triage and customized physiotherapy parameter generation on a single device, effectively shortening the preparation time for battlefield medical treatment.

[0031] (2): This invention introduces a power-off unlocking mechanism based on a system status monitoring module. When the device has sufficient power supply and the microcontroller is operating normally, the multimodal intervention module performs microcurrent pulse therapy; when the hardware status sampling unit detects insufficient power supply or an abnormal code, the electronic path is cut off through the circuit electronic control interlock unit, and the power-off unlocking type solenoid valve mechanism is used to release the constraint on the physical locking mechanism, so that the system degrades to a purely physical ready state. This mechanism ensures that even when the electronic system fails due to extreme battlefield conditions such as electromagnetic interference or battery depletion, the emergency pen can still provide basic mechanical acupuncture intervention capabilities, and has high disaster recovery reliability.

[0032] (3): In the vital signs perception stage, the raw body temperature electrical signal is processed by a moving average filtering algorithm, and the dynamic pupil area change image sequence is processed by an image recognition algorithm combined with a nervous system state norm matrix, reducing the error caused by manual visual observation. In the parameter generation stage, the control state machine module extracts the triage level from the injury assessment results as a dynamic weight coefficient and substitutes it into the physical mapping algorithm for weighted calculation. This data processing method enables the final output microcurrent pulse physiotherapy signal to be dynamically adjusted according to the specific shock degree and nerve inhibition state of the injured person, improving the pertinence of the physiotherapy parameters.

[0043] 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.

[0044] The integrated multifunctional individual soldier TCM intelligent emergency rescue pen of the present invention will be described below with reference to the accompanying drawings.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this invention provides an integrated multifunctional individual soldier's TCM intelligent first aid pen, comprising: an information acquisition component 1, a control component 2, an acupuncture component 3, and a first aid pen body 4. The acupuncture component 3 includes a needle push rod 31, a self-locking buckle 32, a limiting slot 33, a needle body fixing slot 34, a rotating needle storage chamber 35, a second therapeutic needle 36, a positioning slot 37, a needle replacement button 38, and a first therapeutic needle 39.

[0046] The front end of the emergency pen 4 is equipped with an information acquisition component 1, which includes a multimodal vital sign perception module, a physiotherapy end, and a multimodal intervention module.

[0047] The front end of the emergency pen 4 is equipped with a control component 2, which contains an embedded interactive safety feedback module and a control state machine module.

[0048] The acupuncture component 3 is located at the end of the emergency pen body 4. The acupuncture component 3 contains a mechanical acupuncture emergency module and a system status monitoring module.

[0049] This invention provides an integrated multifunctional intelligent first aid pen for individual soldiers using traditional Chinese medicine, comprising the following modules:

[0050] The multimodal vital sign sensing module collects infrared body temperature data and pupil light reflection data, and performs triage and judgment based on the infrared body temperature data and pupil light reflection data to obtain injury assessment results.

[0051] In practical applications, the multimodal vital sign sensing module safely acquires two core physiological indicators of the injured person through non-contact sensors. Its principle is to calculate body surface temperature (i.e., infrared body temperature data) by capturing the intensity of infrared radiation emitted by the human body, and simultaneously record the objective pupillary contraction response (i.e., pupillary light reflection data) by applying light stimulation. These two data objectively reflect the body's blood circulation status and central nervous system activity, respectively. The innovation of this feature lies in changing the traditional, crude mode of individual first aid relying on subjective visual judgment. Its technical effect is improved by cross-validating the two objective data (i.e., triage judgment), thus enhancing the accuracy of initial injury assessment in extreme environments.

[0052] For example, in a field training exercise, a medic uses a first-aid pen to triage a wounded soldier, Zhang San, who was injured by an explosion shockwave. The multimodal vital signs sensing module quickly collects Zhang San's low infrared body temperature data and sluggish pupillary light reflex data, and based on this, determines that he is on the verge of shock, generating a high-risk injury assessment result.

[0053] Regarding the aforementioned body temperature collection, due to the complex battlefield environment, the raw body temperature electrical signal will fluctuate drastically. The specific formula of the preset moving average filtering algorithm is as follows:

[0054]

[0055] In the formula, The infrared body temperature data after smoothing; The preset sampling window length is set to 10. For the first The instantaneous temperature value after conversion of the original body temperature electrical signal collected this time. The technical effect is that by averaging the data through a fixed-length data queue, high-frequency noise interference from cold winds or heat waves in the environment is effectively filtered out, ensuring the reliability of the body temperature data.

[0056] Furthermore, to eliminate measurement errors caused by the attenuation of infrared radiation due to temperature fluctuations in complex outdoor environments and the variable measurement distance of individual soldiers, the infrared signal processing unit integrates an environmental compensation algorithm. Before outputting the final infrared body temperature data, the system uses a thermistor attached to the periphery of the infrared temperature probe to collect the current ambient temperature in real time. The photoelectric ranging module is used to obtain the actual physical distance between the current probe end face and the surface of the injured person's skin. Then, based on the infrared radiation compensation formula:

[0057]

[0058] Filtered reference body temperature Numerical compensation calibration is performed. For the pre-calibrated ambient temperature compensation coefficient, This is the infrared distance attenuation compensation coefficient. This refers to the final packaged and transmitted infrared body temperature data. This compensation logic ensures the absolute accuracy of core vital signs data in extremely cold or hot battlefield environments.

[0059] The preset hypothermia warning threshold is specifically disclosed as 35.0 degrees Celsius. The principle is to use the microcontroller's logic unit to compare the real-time processed data with this constant; once the temperature falls below this threshold, the injured person is considered to be at risk of hypothermia. This operation achieves hardware-level early warning, automatically generating physiological emergency alarms without human intervention.

[0060] For example, in a windy environment, the infrared signal processing unit uses the above formula to average 10 consecutive temperature values ​​with large fluctuations. After filtering out interference, it outputs a stable 34.5 degrees Celsius as the infrared body temperature data of the injured soldier Zhang San. The body temperature risk assessment unit compares the infrared body temperature data of 34.5 degrees Celsius of the injured soldier Zhang San with the low body temperature warning threshold of 35.0 degrees Celsius. If it finds that the temperature is lower than the threshold, the system immediately generates information on the risk of hypothermic shock for Zhang San and sends it to the back-end module.

[0061] The preset modulation frequency is specifically disclosed as 2 Hz. The principle is that the microcontroller outputs a 2 Hz square wave signal to control the yellow pupil stimulation light source to flash regularly, while the image sensor (CMOS camera) is simultaneously activated at a rate of 60 frames per second, completely recording the visual information of the eye before and after illumination. This operation provides a standardized light source stimulation scheme, eliminating evaluation errors caused by inconsistencies in illumination time and light intensity when different personnel use flashlights for testing.

[0062] This section details the algorithm for converting the acquired images into objective medical indicators. The image recognition algorithm employs a lightweight spatiotemporal convolutional neural network model. Specifically, for the high frame rate video stream acquired from the front end, the system first uses adaptive grayscale thresholding combined with morphological closing operations to dynamically and in real-time crop and normalize the pupil region of interest (ROI) in each frame, removing interference from eyelashes and ambient light spots, and extracting a single-channel pupil image sequence with a uniform size of 64×64 pixels. For 2 Hz light stimulation and a sampling rate of 60 frames per second, the system extracts 60 consecutive frames of images in a single inference (i.e., a time window of 1 second, covering the complete light contraction and relaxation recovery cycle) as a multidimensional input tensor.

[0063] The model architecture includes a spatial feature extraction network and a temporal processing network: the spatial feature extraction network contains three consecutive two-dimensional convolutional layers (each with a kernel size of 3×3 and output channels of 16, 32, and 64 respectively) and a max pooling layer, used to extract the geometric edge features of the pupil in a single frame; followed by a Long Short-Term Memory (LSTM) network with 64 hidden layer nodes, used to perform temporal modeling of the shrinkage dynamics of the above 60-frame image sequence in the time dimension; the output of the LSTM is connected to two fully connected layers and a Sigmoid output layer, and finally outputs the light reflection delay value and the area shrinkage magnitude value.

[0064] During the training and deployment phases: Supervised training is performed using a clinical ocular video library with labeled vital signs data, employing a joint loss function of cross-entropy and mean squared error for iterative training. After training, the system uses post-training quantization (PTQ) technology to convert all Float32 floating-point weight parameters in the network to INT8 integer data format, thereby compressing the model size to the KB level. Finally, a lightweight inference engine is embedded in the flash memory of the microcontroller built into the emergency pen, achieving millisecond-level local real-time inference while meeting low-power and low-computing-power hardware constraints.

[0065] The preset multi-level nervous system state norm matrix is ​​a defined two-dimensional feature space matrix. Its first dimension (horizontal axis) corresponds to the normalized light reflection delay value (unit: seconds), and the second dimension (vertical axis) corresponds to the area contraction amplitude value (unit: %). This matrix internally stores three central reference coordinate systems extracted based on large-sample clinical statistics: the central coordinates for the healthy state are set to (0.2, 15), the central coordinates for the mildly inhibited state are set to (0.5, 8), and the central coordinates for the severely inhibited state are set to (1.2, 3). The vector matching operation is specifically implemented as follows: using a microcontroller, the Euclidean distance between the pupil light reflection data coordinates output by the current model inference and the above three central reference coordinates is calculated. By comparing the values ​​of the three Euclidean distances, the state category corresponding to the minimum distance is output as the target central nervous system state level. Based on the above Euclidean distance measurement and coordinate system matching logic, subtle pupil changes that are difficult to distinguish with the naked eye are quantified with high precision, significantly improving the objectivity and reproducibility of neurological function assessment.

[0066] For example, the pupil stimulation control unit drives yellow light to illuminate the eyes of the injured soldier Zhang San at a frequency of 2 Hz. Simultaneously, the image sensor continuously records a sequence of images showing the dynamic change in pupil area as Zhang San's pupils shrink under light stimulation. The light reflection evaluation unit inputs the image sequence of the injured soldier Zhang San into a trained model, inferring that Zhang San's light reflection delay is 1.0 second and the area contraction amplitude is 4%. These two values ​​are then matched against the distance in the multi-level nervous system state norm matrix to determine that Zhang San's corresponding central nervous system state level is "severe inhibition," and the corresponding triage label information is generated.

[0067] The system status monitoring module acquires the system power supply status information of the built-in power supply and the hardware operation status of the microcontroller.

[0068] In practical applications, the system status monitoring module performs a self-health check on the device. Its principle is to read the battery voltage through the microcontroller's analog-to-digital converter pin to calculate the remaining power percentage (i.e., the system power supply status information), and directly read the hexadecimal register code at the central processing unit's lower level (i.e., the hardware operating status word) to determine if the chip has crashed or encountered a logic error. This provides hardware-level safety decision-making basis for subsequent electrical pulse intervention, preventing the device from operating with defects.

[0069] High-speed, timed sampling means the system continuously checks itself in millisecond-level time slices. When it detects either a complete power depletion (below 15%) or a core chip crash (register status throws 0xFF), the system bypasses potentially frozen software and directly controls a specific pin to output a 0-volt voltage (i.e., the low-level hardware cutoff signal). The technical effect is that through hard-wired level signal intervention, the highest priority fault response is achieved, ensuring the safety of the injured. Upon receiving a danger signal, this invention discloses the core execution actions from electronic paralysis to physical takeover. The internal hardware interlock control circuit uses relays to physically disconnect the power supply to all electronic treatment modules to prevent current runaway. The power-off unlocking solenoid valve mechanism is a safety-guided design; it only generates magnetic force to lock the mechanical structure when energized; once the power supply is cut off (power failure), the internal spring immediately pushes open the valve core, releasing the physical locking mechanism. Its technical effect is to automatically activate a purely mechanical backup emergency function in the event of complete electronic system failure.

[0070] For example, during the rescue of Zhang San, the battery voltage suddenly dropped due to extreme low temperature, and the calculated remaining charge was only 5%. The hardware status sampling unit immediately determined that the system was abnormal and output a low-level hardware cutoff signal on the internal bus. In the aforementioned low-temperature power supply scenario, the circuit electronic control interlock unit received the cutoff signal and forcibly cut off the power supply to all circuits inside the emergency pen. Subsequently, the solenoid valve lost current and rebounded, the emergency pen made a "click" sound, completely disengaging from the electronic control lock, ready to perform purely mechanical physical acupuncture on Zhang San.

[0071] The control state machine module receives the injury assessment result, the infrared body temperature data, and the pupil light reflection data, and, in conjunction with the triage level in the injury assessment result, maps the infrared body temperature data and the pupil light reflection data to the target physiotherapy current amplitude and the target physiotherapy current frequency, respectively.

[0072] In practical applications, the control state machine module serves as the core computing hub, converting physiological indicators into electrical parameters required for traditional Chinese medicine electroacupuncture therapy. In principle, the system uses the collected data on low body temperature and weak nerve reflexes as mathematical variables. Through an internally fixed algorithm, it calculates the intensity of the microcurrent used to stimulate acupoints (i.e., the target therapeutic current amplitude) and the speed of the pulse stimulation (i.e., the target therapeutic current frequency). This enables dynamic adaptive adjustment of emergency intervention plans, providing customized electrical pulse parameters for different injured individuals.

[0073] For example, after receiving the injury assessment result of the injured soldier Zhang San as being in high risk, the control state machine module maps his low infrared body temperature data to a high target physiotherapy current amplitude and his slow pupillary light reflection data to a high-frequency target physiotherapy current frequency, thus tailoring powerful electrical stimulation parameters for the injured soldier Zhang San.

[0074] This invention discloses a human-machine interaction mechanism for operators to issue commands to devices. The principle of real-time polling monitoring is that the microcontroller repeatedly reads the level status of peripheral pins at fixed time intervals (e.g., 5 milliseconds). When the knob is turned, the internal metal spring contacts or disconnects, generating high and low level changes (i.e., the physical contact switching electrical signal). The system interprets this change as a digital code representing different operating modes. By utilizing a highly reliable physical knob design, accurate input is ensured even when the operator is wearing tactical gloves.

[0075] The bidirectional free switching logic means that the system does not enforce a rigid, irreversible sequence of "detection before treatment." Operators can switch between the pre-detection state (data acquisition) and the pulse therapy state (current output) at any time as needed. The initial switching command ensures that sensitive vital sign data in memory is only retrieved and used when electroacupuncture intervention is clearly required. This operation provides significant tactical flexibility to the rescue process, facilitating repeated assessments of treatment effectiveness by medical personnel.

[0076] For example, a medic wearing non-slip gloves turns the knob in the middle of the first-aid pen. The knob signal monitoring unit captures the change in circuit continuity and converts it into a digital state transition condition requesting entry into treatment mode. Based on the digital state transition condition, the medic puts the device into the pulse therapy state for the injured soldier Zhang San. Two minutes later, to observe Zhang San's recovery, the medic operates the knob again. The bidirectional free-switching logic allows the device to immediately return to the pre-detection state and remeasure Zhang San's pupils.

[0077] Since data acquisition and treatment are different operating nodes within the system, the parameter transfer and storage unit acts as a "data temporary storage pool." When a read command is received, it packages the originally discrete temperature values, amplitude values, and diagnostic labels into a one-dimensional array format (i.e., the vital sign vector to be mapped) in a fixed order. This solves the data loss problem under cross-mode operation and ensures the integrity of the input data for subsequent calculations.

[0078] After the preliminary data is complete, this section discloses the mathematical kernel for generating personalized physiotherapy plans. The specific formula of the physical amplitude mapping algorithm is disclosed as follows:

[0079]

[0080] In the formula, The target therapeutic current amplitude; The dynamic weighting coefficient has a complete lookup table mapping relationship based on the triage label information: when the triage label information is healthy... When set to 0 (i.e., blocking the output of the therapeutic current), and the triage label information is "mild suppression"... Set to 1.2, when the triage label information is "severe suppression" Set to 1.8; The preset body temperature reverse gain constant has a value of -0.3; The first independent variable is (i.e., the infrared body temperature data); The preset base bias amplitude is set to 12.0 mA.

[0081] The specific formula for the frequency mapping algorithm is disclosed below:

[0082]

[0083] In the formula, The target therapeutic current frequency; The preset reflection sensitivity gain constant has a value of -80.0; The second independent variable is (i.e., the area shrinkage amplitude value in the pupil light reflection data); The preset maximum intervention frequency is set to 90 Hz. This allows for the formulation of medical experience, enabling the device to adaptively calculate precise electrical pulse stimulation parameters.

[0084] For example, after issuing the read permission command, the parameter transfer storage unit merges the temporarily stored data of Zhang San's 34.5 degrees Celsius, 4% contraction amplitude, and "severe suppression" label into a structured vital sign vector to be mapped: [34.5, 0.04, 3]. For the injured soldier Zhang San, the following is extracted: It is 1.8. Substituting 34.5 into the amplitude formula, the mapping matrix calculation unit calculates... It is 2.97 mA; Substituting 0.04 into the frequency formula, we obtain... The frequency is 86.8 Hz. This module encapsulates these two values ​​into Zhang San's personalized physiotherapy parameters.

[0085] The multimodal intervention module, when the system power supply status information meets the power supply threshold and the hardware operation status word is a normal code, uses the target physiotherapy current amplitude and the target physiotherapy current frequency to drive the ring electrode to output a microcurrent pulse physiotherapy signal.

[0086] In practical applications, the power supply threshold is defined as a remaining battery percentage of 15% or greater; the normal code is explicitly defined as hexadecimal code 0x00. When the above safety prerequisites are met, the multimodal intervention module generates an electrical signal conforming to the customized parameters through its internal power amplification circuit, and introduces it into acupoints through the ring electrode attached to the skin. Ensuring that the device does not suffer waveform distortion due to low battery power, a non-invasive electroacupuncture therapy is provided to improve the vital signs of the injured person in a non-invasive manner.

[0087] For example, since the power supply is sufficient and there is no fault, the multimodal intervention module controls the ring electrode to continuously output the microcurrent pulse therapy signal to the Neiguan acupoint of the injured soldier Zhang San according to the specific amplitude and frequency calculated by the previous module, so as to help stabilize his pulse.

[0088] Human skin has contact resistance. The specific criterion for determining the effective contact closed-loop state is that the real-time contact impedance feedback value is lower than a preset 45 kiloohms. The principle is that before the main circuit is turned on, the device outputs an extremely weak probe current to measure the resistance, thereby confirming that the electrode is firmly pressed against the skin. Its technical effect is to effectively prevent no-load discharge from damaging the circuit when the electrode is suspended, and to avoid the stinging sensation caused by discharge during a loose connection. After confirming safety, this invention discloses the method for generating the actual treatment waveform. Its principle is to utilize the pulse width modulation (PWM) technology of a microcontroller to forcibly shape the originally uniform high-frequency square wave signal (i.e., the underlying reference pulse signal) into a specific amplitude and frequency result calculated by the aforementioned formula by changing the voltage height of the peak and the period width of the square wave. Its technical effect is to achieve a high-fidelity conversion from control logic to physical electrical energy, ensuring that the current injected into the body strictly follows the personalized parameters.

[0089] For example, when the medic places the ring electrode on Zhang San's arm, the electrode impedance feedback unit reads that the impedance has dropped to 30 kiloohms, confirming a good fit, and then outputs the pulse enable control signal to allow the output of pulse current. After receiving the opening signal, the microcurrent pulse modulation unit dynamically modulates the underlying square wave into a 2.97 mA, 86.8 Hz microcurrent pulse therapy signal specific to Zhang San, and continuously outputs it to Zhang San through the electrode.

[0090] The mechanical acupuncture emergency module releases the electrical control constraint of the physical locking mechanism when the system power supply status information is lower than the power supply threshold or the hardware operation status word is an abnormal code, so that the system enters a purely physical ready state, allowing external mechanical input to drive the needle push rod 31 to eject to the target needle insertion depth position, and allowing external torque to drive the needle storage and changing chamber to rotate step by step.

[0091] In practical applications, such as Figure 5 , Figure 6 and Figure 7As shown. During normal use of the device, the solenoid valve in the acupuncture component 3 receives data and drives the first therapeutic needle 39 on its outer side to move outward. The first therapeutic needle 39 is located at the axial position of the acupuncture component 3. The acupuncture treatment process can be completed by the extension and retraction of the first therapeutic needle 39. In addition, this module discloses the final safety redundancy design of the device. The exception code is explicitly disclosed as hexadecimal code 0xFF (representing system crash). When the device malfunctions due to power loss from severe cold (battery level below 15%) or strong electromagnetic interference, the system uses the power loss rebound principle to release the internal solenoid valve, thereby releasing the physical locking mechanism. At this time, the device relies on the mechanical energy generated by the operator's hand pressing (i.e., the external mechanical input) to drive the internal spring, pushing the push rod to insert the second therapeutic needle 36 (i.e., the disposable sterile acupuncture needle) into the skin at high speed, and the spare needle can be replaced by manual twisting (i.e., the external torque). Its technical effect is to give the electronic device a baseline availability under severe conditions of complete power failure, ensuring the continuation of emergency actions.

[0092] For example: Suppose that during the transfer of injured soldier Zhang San, the battery of the emergency pen is damaged, causing the charge to drop to 0%. At this time, the solenoid valve loses power, and the physical locking mechanism automatically releases. The medic then presses the needle replacement button 38 at the tail (i.e., the physical trigger button) with his hand, relying on a purely mechanical spring to eject a sterile acupuncture needle into the injured soldier Zhang San's Zusanli acupoint, completing the physical acupuncture intervention. Figure 6 As shown, the inside of the needle push rod 31 is provided with a limiting groove 33. The limiting groove 33 has three adjustable positions: 3mm limiting groove, 5mm limiting groove and 8mm limiting groove. A mechanical spring is provided on one side of the needle push rod 31. The mechanical spring is connected to the needle replacement button 38 provided at the tail of the emergency pen body 4. A needle body fixing groove 34 is connected to the front end of the needle push rod 31. The outside of the needle body fixing groove 34 is connected to the second physiotherapy needle 36. When the rotating needle storage chamber 35 (i.e. the needle storage and replacement chamber) rotates, it drives the second physiotherapy needle 36 to rotate. That is, when the second physiotherapy needle 36 coincides with the positioning groove 37, the needle push rod 31 pushes the second physiotherapy needle 36 to complete the operation of mechanical acupuncture.

[0093] Different acupoints on different parts of the body require acupuncture at different depths. The operator manually rotates the three-position limiting ratchet mechanism. In this invention, the three-position limiting ratchet mechanism includes a rotating needle storage chamber 35, a second therapeutic needle 36, a positioning groove 37, and a needle change button 38. Rotating the three-position limiting ratchet mechanism causes the internal guide post to slide into physical slots of different depths. In this invention, the physical slots are adjustable in three positions: 3mm, 5mm, and 8mm. Simultaneously, the spiral cam track forces the internal thick spring to be compressed, thus converting the rotational mechanical energy of the hand into the elastic potential energy of the spring. The technical effect is that, even without electricity, the physical depth of needle insertion into the body can still be precisely controlled, while simultaneously completing the power reserve for the next ejection.

[0094] When the needle change button 38 at the tail is pressed, the mechanical blocking block holding the spring (i.e., releasing the axial constraint) is forcibly removed, and the spring releases its potential energy to drive the ejector rod 31 to strike the needle at high speed and pierce the skin. When the ejector rod reaches the bottom, the one-way barb structure (the self-locking buckle 32) will mechanically lock it to prevent rebound. The technical effect is that the high instantaneous force of the mechanical ejection greatly reduces the pain when the needle pierces the skin, and the one-way locking ensures stable needle retention.

[0095] This invention designs a cylindrical body with multiple parallel cavities, known as sterile needle slots, each containing a second therapeutic needle 36. Each cavity holds one unused second therapeutic needle 36. This parallel arrangement ensures that regardless of the chamber's rotation, one cavity will always be aligned with the rear needle pusher 31. The technical effect is that this portable emergency device possesses the ability to carry its own consumables and perform multiple consecutive mechanical needle insertions, avoiding contamination from conventional puncture needles used on the battlefield. When the operator manually rotates the needle reservoir 35, the second therapeutic needle 36 rotates accordingly. Because of the spring-loaded steel pins on the periphery, each time the device rotates to a specific angle, the pins are forced into the positioning grooves 37 on the outer wall by the spring force, producing a noticeable damping sensation, thus forcing the rotating needle reservoir 35 to stop rotating and precisely align. This technical effect ensures the accuracy of blind needle changing, preventing slight misalignment from causing the needle pusher 31 to deviate or jam the internal mechanical structure.

[0096] The integrated multifunctional individual soldier TCM intelligent first aid pen proposed in this invention also includes an embedded interactive safety feedback module.

[0097] Specifically, this module discloses a dual-safety mechanism to prevent accidental triggering of the device when it is not in operation. The independent physical anti-accidental-touch lock structure is a mechanical lever. When the lever is pushed to the "locked" position, on the one hand, a sensor generates an electrical signal to forcibly cut off all discharge circuits (preventing accidental electric shock), and on the other hand, its physical body directly locks the sliding track of the tail button, preventing it from being pressed (preventing accidental discharge of the mechanical spring). Its technical effect is to completely eliminate the danger of accidental triggering of the device during individual soldier carrying from both electrical and mechanical physical dimensions. Finally, this module discloses a visual output window for the device's operating status. This window is integrated into the control component 2 located in the middle of the emergency pen body 4. This unit summarizes the current status (detection or treatment, mode type), discharge current magnitude (intensity level), and remaining percentage of battery power via an internal communication bus, and drives a micro-electronic display to illuminate this information on the external screen of the control component 2. Its technical effect is to provide the operator with a highly integrated, intuitive, and clear device status monitoring panel. In addition, multiple sets of high-precision human acupoint maps and scale lines are printed on the outer side of the rotating needle storage chamber 35 using laser etching technology. Non-professional medical personnel can refer to the map to align the points and achieve accurate positioning without needing a deep understanding of traditional Chinese medicine.

[0098] The present invention has the following advantages:

[0099] (1): This invention integrates a multimodal vital sign sensing module, a control state machine module, and a multimodal intervention module into a single pen body. Through data flow within the system, infrared body temperature data and pupillary light reflection data, after completing the initial vital sign acquisition, are directly mapped by the control state machine into the target physiotherapy current amplitude and target physiotherapy current frequency. This dual integration of structure and algorithm changes the traditional situation of fragmented functions and disconnected assessment and intervention in individual first aid equipment, enabling rescuers to complete automated triage and customized physiotherapy parameter generation on a single device, effectively shortening the preparation time for battlefield medical treatment.

[0100] (2): This invention introduces a power-off unlocking mechanism based on a system status monitoring module. When the device has sufficient power supply and the microcontroller is operating normally, the multimodal intervention module performs microcurrent pulse therapy; when the hardware status sampling unit detects insufficient power supply or an abnormal code, the electronic path is cut off through the circuit electronic control interlock unit, and the power-off unlocking type solenoid valve mechanism is used to release the constraint on the physical locking mechanism, so that the system degrades to a purely physical ready state. This mechanism ensures that even when the electronic system fails due to extreme battlefield conditions such as electromagnetic interference or battery depletion, the emergency pen can still provide basic mechanical acupuncture intervention capabilities, and has high disaster recovery reliability.

[0101] (3): In the vital signs perception stage, the raw body temperature electrical signal is processed by a moving average filtering algorithm, and the dynamic pupil area change image sequence is processed by an image recognition algorithm combined with a nervous system state norm matrix, reducing the error caused by manual visual observation. In the parameter generation stage, the control state machine module extracts the triage level from the injury assessment results as a dynamic weight coefficient and substitutes it into the physical mapping algorithm for weighted calculation. This data processing method enables the final output microcurrent pulse physiotherapy signal to be dynamically adjusted according to the specific shock degree and nerve inhibition state of the injured person, improving the pertinence of the physiotherapy parameters.

The first aid pen according to claim 1, characterized in that, The system status monitoring module includes: The hardware status sampling unit periodically and at high speed samples the remaining power percentage data of the built-in power supply as the system power supply status information, and samples the underlying register status data of the microcontroller as the hardware operating status word. When the remaining power percentage data is lower than the power supply threshold or the underlying register status data shows the error code, the system is determined to be in an abnormal state and outputs a low-level hardware cut-off signal. The circuit electronic interlock unit receives the low-level hardware cut-off signal and, under the action of the internal hardware interlock control circuit, directly cuts off the power supply path between the multimodal vital sign sensing module and the multimodal intervention module. At the same time, it releases the electronic limit constraint on the physical locking mechanism and disengages from the locked state through the power-off unlocking solenoid valve mechanism.

The first aid pen according to claim 1, characterized in that, The mechanical acupuncture emergency module includes: The depth limit adjustment unit, after the physical locking mechanism releases the electronic control constraint, allows the three-position limit ratchet mechanism set at the tail of the integrated pen body to respond to the external rotation physical operation to select the target needle depth position. The target needle depth position includes a 3mm limit groove, a 5mm limit groove and an 8mm limit groove. During the process of the three-position limit ratchet mechanism rotating and locking into the corresponding groove, it simultaneously compresses the built-in needle main spring to deform and complete the ejection energy storage. The physical trigger self-locking unit, after the built-in needle main spring has completed energy storage, responds to the mechanical pressing stroke operation of the tail physical trigger button to release the axial constraint structure, drives the ejector pin to instantly eject along the pen body axis, and performs one-way mechanical locking through the self-locking buckle when it moves to the physical limit end position.

The automatic needle changing positioning unit, after the physical locking mechanism releases the electrical control constraint, allows the outer wall of the needle storage and changing chamber to receive the externally applied tail-end turning and shifting torque, causing the needle storage and changing chamber to rotate at a fixed angle step around the central rotation axis. When the physical positions of two adjacent sets of sterile needle slots are switched, the elastic positioning pins arranged in a ring on the outer wall fall into the positioning holes of the slot, ensuring that the sterile needle slot currently in the working position coincides with the axis of the ejector pin.

10.
