Description

Technical Field

[0001] The invention relates to a dummy for simulating military physiological indicators. Background Art

[0002] Military physiological dummies can simulate the ECG, respiration, blood pressure, blood oxygen saturation and body temperature of real people in various complex environments. By simulating multiple physiological parameters at the same time for coupling, it can more comprehensively and objectively evaluate the performance of soldiers' individual protective equipment in protecting and saving lives when the parameters of human physiological indicators change. On the one hand, it can more comprehensively and objectively evaluate the performance of soldiers' individual protective equipment in protecting and saving lives when the parameters of human physiological indicators change; on the other hand, it can serve as a test platform to evaluate the various types of injuries that soldiers may face in various battlefield environments, and provide a basis for the optimal design of various military protective products.

[0003] Traditional dummy models are only used for structural experiments. Physical effects such as explosion impacts affect the dummy's human body structure or external skin to cause damage, so as to test the dummy's external equipment, thereby achieving the purpose of researching and developing new equipment. In the process of developing military protective equipment, the soldier's physical state and physiological parameters are directly related to the soldier's life safety. Therefore, the protection ability of protective equipment directly determines the soldier's life safety. The existing military test dummies are mainly based on dynamic physical and mechanical test items, and there are few related equipment for monitoring the soldier's physical physiological indicators. For this reason, it is planned to design and invent a human vital signs simulation device to give full play to its strong versatility, high simulation, convenient setting and adjustment, compact structure, and safe and economical characteristics, so as to facilitate in-depth understanding and targeted development of soldier status monitoring during the development of military protective equipment. Through the development of this equipment, it can be used for the intelligent active protection performance verification of protective life-saving equipment in complex battlefield environments. By controlling the changes in the physiological parameters of the simulation dummy, the real physiological indicators of the soldier in a complex battlefield environment are simulated, and the corresponding protective life-saving performance of the equipment is evaluated when the soldier's physiological indicators change.

[0004] At present, such facilities are mainly used in medicine to provide simulated signals for various medical rescue equipment. The types and forms of signals are significantly different from the signals required for specific groups such as soldiers and characteristic scenes such as battlefields. In addition, after contacting and inquiring about information with some domestic and foreign manufacturers of life detection instruments, although each manufacturer has product factory inspection equipment, the equipment is large in size and inconvenient to use; the signal source type is single, the versatility is not strong, the environmental tolerance is not high, and the life span is unreliable; the function is simple and cannot reflect extreme and complex scenes such as the dynamic changes of vital signs with operating conditions; the price is high and the promotion is not strong. Therefore, the development of special physiological index simulation dummies for soldier protective equipment has certain innovation and application prospects. Summary of the invention

The controller includes a control box and a system main control board, and the control box is used to input control instructions and connect to an external terminal; the system main control board is connected to each module through an interface, and the instructions issued by the control box are output to each module to simulate physiological indicators.

[0030] In one embodiment, Figure 3 As shown, the ECG simulation module converts the digitized ECG signals into digital-to-analog signals respectively, and outputs them through a multi-channel digital-to-analog conversion circuit. After each channel is subjected to signal attenuation, the amplitude requirement of the ECG equipment for collecting signals is met, and the signals are provided to ECG medical equipment for signal collection. The ECG simulation module is connected to the ECG signals through the system main control board. The ECG signals include typical ECG waveform signals and specific disease signals, which are stored through a mobile storage device, including the sampling rate, waveform range, amplitude size and number of data channels of the ECG signals. The number of data channels in the ECG simulation module is set to 3. According to the 3-lead monitoring unit, bioelectric signal simulation sheets are installed at the lower edge of the midpoint of the right clavicle, the fourth intercostal space of the left anterior axillary line, and the right side below the xiphoid process to emit bioelectric signals and transmit them to the detector.

[0031] The digitized ECG signal consists of the following parameters: 1. Sampling rate (the number of samples collected per second); 2. Amplitude value, corresponding to the amplitude of the ECG signal; 3. Multi-channel ECG waveform data.

[0032] To ensure the most realistic restoration of the digital waveform, this module sets the timer cycle according to the sampling rate for time control during DA output; through the attenuation circuit and the amplitude selection calculation during DA output, the final output analog signal meets the amplitude value of the ECG signal; through multiple DA channel outputs, corresponding to the ECG waveform data of multiple channels, to restore the ECG waveform of multiple channels. Heart rate simulation error: ≤±3 times / min; value simulation error: ≤±5%; resolution: ≤5bpm.

[0033] In one embodiment, the breathing simulation module outputs the digitized breathing signal through a digital-to-analog conversion circuit to drive a field tube, and simulates the impedance change of the human body through the impedance change of the field tube for breathing detection of medical equipment.

[0034] In one embodiment, the breathing simulation module can also use the 3rd to 7th pairs of ribs as rib simulation structures according to the human breathing characteristics and radar detection principles to simulate the chest movement during human breathing by moving forward and backward. When the human tissue structure moves, the structure can be driven to move forward and backward to generate displacement, simulating the micro-movement of the body surface caused by breathing. The trunk in the human tissue structure is provided with simulated skin, which forms a detachable fixed connection with the chest simulation structure of the trunk to achieve simulated breathing movement.

[0035] In one embodiment, the breathing simulation module can also be provided with a device for simulating the human chest cavity, i.e., the respiratory tract, according to the movement conditions and movement characteristics of the human chest cavity and lungs during breathing. The device is provided with a sealed and transparent simulated chest cavity, a simulated respiratory tract is implanted inside the chest cavity, and two air bags are connected to the ends of the simulated respiratory tract to simulate the left and right lungs, and then an air source is connected from the side line of the simulated chest cavity to input positive and negative alternating air pressure to form an air pressure difference to simulate the action of inhalation and exhalation. Breathing simulation error: ≤±3 times / min, simulation error ≤±3bpm, and the breathing volume range can be arbitrarily adjusted within the range of 0.1L to 2.0L.

[0036] In one embodiment, the blood pressure simulation module is provided with a detection gas circuit. According to the principle of blood pressure measurement, the human pulse vibration is simulated at different pressures and provided to the medical equipment for blood pressure signal acquisition. The static pressure value in the gas circuit is always detected during operation. According to the set blood pressure simulation value, when the gas pressure in the gas circuit is collected, according to the principle of oscillometric method, different air pressure changes need to be generated in the gas circuit for different static pressure values. The CPU controls the stepper motor to generate displacement to drive the gas circuit to generate air pressure changes of different amplitudes to simulate the pulse of the human body. When measuring blood pressure, this module controls the stepper motor through the control circuit, and according to the principle of non-invasive blood pressure measurement, simulates the pulse of the human body at different pressures to generate small air pressure changes in the gas circuit. By receiving the command of the host computer, different blood pressure parameter values ​​are simulated according to the command during the simulation output. Blood pressure simulation error: ≤±8mmHg.

[0037] In one embodiment, the blood oxygen simulation module uses a photoelectric tube to receive the light-emitting driving timing from the oximeter to drive the dual-wavelength light-emitting tube of the control module part, and modulates the data containing the pulse signal to the optical signal output circuit after digital-to-analog conversion. The analog-to-digital conversion output drives the light-emitting tube and converts it into an optical signal for output. The blood oxygen simulation module is provided with a light emitter for emitting red light and infrared light to simulate the blood oxygen saturation value and pulse frequency value. The light emitter is located at the earlobe of the head. The transmissive pulse oximeter is designed at the earlobe using the photoelectric simulation principle. Two optical sensors are provided on the lower surface of the photoelectric simulation earlobe, which are used to detect red light and infrared light signals respectively, and a light emitter is installed on the upper surface. The functional module group emits red light and infrared light to the two photosensitive diodes D1 and D2. The light intensity of red light (R) and infrared light (IR) is obtained respectively through the operational amplifier and the optical separator. The microprocessor gives the blood oxygen saturation value and pulse frequency value to be simulated, and the electrical signals of R and IR are modulated by AC and DC respectively. The modulated pulses are output and converted into optical signals by IR LED, and then the blood oxygen simulation that can be received by the blood oxygen detection probe is emitted. The blood oxygen simulation accuracy is: ≤±0.5℃.

[0038] In one embodiment, the body temperature simulation module includes temperature detection and temperature heating; a soft silicone heating wire device is driven by a field effect tube to generate heat, and the temperature value of the silicone heating pad is collected through temperature detection for temperature correction, thereby generating heat to simulate the change of human body temperature, and providing it to the temperature sensor in the monitor to collect temperature changes; the temperature of the body surface or body cavity is measured by utilizing the characteristic that thermistors present different resistance values ​​with human body temperature; the signal of the thermistor in the body temperature sensor is amplified and filtered, and then converted into a digital signal through A / D, and the temperature corresponding to the thermistor is obtained according to the digital signal.

[0039] The body temperature simulation module is provided with a heating element, the interior of which is made of all copper and the exterior is made of heat-insulating non-metallic materials, and is arranged in the armpits, anus and ears of the human body. It is designed according to the requirements for radiation sources in "JJF1107-2003 Calibration Specifications for Infrared Thermometers for Measuring Human Body Temperature", and the main performance index parameters include: cavity emissivity ε = 0.998, temperature control environment temperature coefficient of ± 0.01 ° C / 10 ° C. The temperature control unit and the temperature measurement unit form feedback to ensure that the internal temperature control stability is ≤ 0.02 ° C / 30min, and the radiation temperature uncertainty is 0.07 ° C. The temperature measurement range of the standard cavity under constant temperature conditions is 25.00 ~ 50.00 ° C, the maximum allowable error is ± 0.5 ° C, and the temperature display resolution is 0.01 ° C.

[0040] In one embodiment, the range of motion of the leg assembly is as shown in Table 6, Table 7 and Table 8: The eye movement simulation module imitates the movement of human eyes. Each eyeball is equipped with a high-definition camera and an inertial measurement sensor unit to realize the eye movement and blinking functions. The movement of human eyes is very complex. There are five basic movement patterns: (1) Saccade, also called jerkiness, refers to the rapid shift of the human eye's line of sight from the current viewpoint to another viewpoint at a speed of about 200° / s.

[0041] (2) Smooth Pursuit The human eye can track the movement of a slowly moving target. For a slowly moving object in the field of vision, the eyeball initially captures the target through jerk movements and then switches to smooth pursuit. The maximum speed of smooth pursuit is usually 50° / s.

[0042] (3) Vergence or Disjunctive Movement: When an object in the visual field moves from far to near or from near to far, the two eyeballs rotate in opposite directions at the same time to ensure accurate imaging of the object. When the object moves from far to near, the eyeballs move in a convergent manner, and the visual axis angle increases. When the object moves from near to far, the eyeballs move in a disjunctive manner, and the visual axis angle decreases. The speed of the vertigo movement does not exceed 20° / s.

[0043] (4) Vestibular-ocular reflex (VOR) When a person's head moves suddenly and quickly, the eyeballs need to move in the opposite direction to ensure that the target is within the field of vision. This movement is caused by vestibular stimulation and is therefore called the vestibular-ocular reflex.

[0044] (5) Optokinetic reflex (OKR), also known as dynamic vision, refers to the movement of the eyeball to ensure that objects are seen clearly when the visual field moves violently. The strength of dynamic vision varies the most between different people.

[0045] In one embodiment, the bionic eye can simulate the movement of the human eye, and each eyeball is equipped with a high-definition camera and an inertial measurement sensor unit. In terms of the electronic control system, an MCU main control unit is used, and a high-performance GPU image control system, a drive control system, and a posture control system are equipped with multiple motors to achieve eyeball movement and blinking functions: The bionic left eye movement consists of two motors, one of which is installed parallel to the horizontal plane and controls the up and down movement of the bionic eye through a horizontal connecting rod; the other motor is installed on a vertical plane and controls the left and right movement of the bionic eye through left and right horizontal connecting rods. The attitude control system is connected to the drive control system and drives the bionic eye movement control together with the image control system.

[0046] In one embodiment, distributed sensors are installed on the head component, neck component, shoulders of the upper torso component, and knees of the leg components, which have the function of carrying general electrical measuring equipment; a data acquisition device is installed in the chest cavity of the upper torso to record or telemeter the transmitted data signals.

[0047] In one embodiment, the expansion module is provided with an external interface to expand other modules required for subsequent product iterations.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than a limiting technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
