Description

Technical Field

[0001] The present invention relates to the technical field of heat control, and in particular to a heat control system and method for body temperature management simulation training. Background Art

[0002] Under high temperature conditions in summer, whether it is regular physical activities or high-intensity physical training, the human body will face huge physiological challenges. When the external environment temperature is too high and the individual is doing strenuous exercise, if the heat generated in the body cannot be dissipated in time and effectively, the body temperature will rise sharply, leading to heat stroke, and in severe cases, it may even develop into exertional heat stroke. This disease is known for its rapid onset and severe condition. If it is not intervened and treated in time, it will pose a serious threat to the patient's life and cause immeasurable losses to the combat effectiveness of the troops.

[0003] However, currently, the basic level of the army, the first aid scene and the rescue personnel in the hospital generally have insufficient understanding of heat stroke and lack the knowledge and skills to effectively deal with this emergency. This situation urgently requires us to strengthen the training of temperature management skills in high temperature environments in the fields of medical training and emergency rescue to improve the emergency response capabilities of relevant personnel.

[0004] Unfortunately, existing simulation training equipment has obvious deficiencies in simulating the rapid changes in body temperature and its management process in a high temperature environment. Most of these devices only focus on simulating basic vital signs, such as heart rate, blood pressure, etc., while ignoring the complexity of the temperature regulation mechanism under high temperature conditions and the resulting rapid rise and fall of body temperature. This limitation makes it impossible to truly reproduce the actual situation of human body temperature changes in a high temperature environment during the training process, thereby limiting the training effect and making it possible for trainees to make quick and accurate judgments and responses when faced with real situations.

[0005] Therefore, it is particularly important to develop a heat control system that can fully simulate the rapid changes in body temperature and its management process in a high temperature environment. Summary of the invention

[0049] like Figure 1 to Figure 3 As shown, a heat control system and method for body temperature management simulation training of the present invention includes:

[0050] Simulated human skin, covering the head, neck, torso, arms and lower limbs, creating a simulated human appearance;

[0051] A closed-loop temperature control circuit board is set inside the simulated human skin to control body temperature;

[0052] The core body temperature regulation module is arranged in the abdominal area of ​​the simulated human skin and is electrically connected to the closed-loop temperature control circuit board to regulate the simulated body temperature;

[0055] The body temperature measurement area is set in the cochlea, pharynx, armpit and anus of simulated human skin, and is connected to the closed-loop temperature control circuit board for real-time display of simulated body temperature.

[0056] Specifically, the heat control system and method proposed in the present invention provide a comprehensive and effective solution for temperature management simulation training in high temperature environments through technical features such as highly simulated simulation experience, precise temperature regulation capability, comprehensive heat exchange simulation, real-time temperature monitoring and feedback, and diversified training modes, thereby significantly improving the authenticity and effectiveness of training.

[0057] Specifically, the simulated human body is composed of a head and neck (with facial features and an oral structure), a torso, arms and lower limbs; the head and neck, arms and lower limbs are connected to the torso, and a simulated human skin made of a polymer material (with a dust and water resistance rating of IP68) is attached to the surface to form a soft skin layer of the human body; the interior of the torso is composed of a thoracic cavity structure and an abdominal cavity structure.

[0059] In some embodiments, a closed-loop temperature control circuit board includes:

[0060] Microcontroller;

[0061] The thermosensitive detection module includes a first temperature sensor and a second temperature sensor, which are arranged in the core body temperature regulation module, and further includes a third temperature sensor, which is arranged on the body surface and electrically connected to the microcontroller for detecting and transmitting temperature data;

[0062] The user interface module includes a key input module, a display module and a timer module, and is electrically connected to the microcontroller for inputting preset body temperature parameters, displaying body temperature data and operating status, and recording the time of the body temperature adjustment process.

[0063] Specifically, the examiner inputs the preset body temperature value for the assessment in the user interface, the closed-loop temperature control circuit board is connected to the core water tank, the temperature adjustment control element and the first temperature sensor are adjusted and data is collected, and the PWM duty cycle is regulated by processing the data and comparing it with the preset value, maintaining a constant output of heat power, maintaining the set temperature of the core water tank, simulating the preset human core temperature, and starting the timer module. At the same time, the display module displays the body temperature data in real time and prompts whether the preset temperature is reached and whether training can be started. The temperature data collected by the second temperature sensor can be compared with the standard temperature value for successful treatment in real time. If the target body temperature is reached within the specified time, the TTM training is judged to be qualified, otherwise it is judged to be a failure.

[0064] In some embodiments, the core body temperature regulation module includes a heat source unit, a core water tank, a central water storage tank, a first water pump, and a second water pump;

[0065] The heat source unit is connected to the core water tank, the core water tank is connected to the central water storage tank through a first water pump, and the central water storage tank forms a circulating water circuit with the core water tank through a second water pump.

[0066] Specifically, the core water tank and the central water storage tank are arranged in the simulated human abdominal cavity, and a first pipeline and a second pipeline are formed between the core water tank and the central water storage tank; the first pipeline and the second pipeline are both composed of insulated hoses; the first water pump is installed in the first pipeline, and the second water pump is installed in the second pipeline; the first pipeline is used to provide water medium from the core water tank to the central water storage tank, and the second pipeline is used to provide water medium from the central water storage tank to the core water tank; the central water storage tank can be connected to the simulated human body surface heat exchange area and skin temperature measurement area through a conductive water circulation pipeline.

[0067] In some embodiments, the heat source unit is built into the core water tank, and the heat source unit includes:

[0068] A heating plate (soft silicone electric heating plate) is installed at one end of the core water tank and is used to heat the water in the core water tank. In this embodiment, three heating plates are provided.

[0069] The cooling plate (semiconductor cooling plate) is installed at one end of the core water tank and is close to the heating plate, and is used to cool the water in the core water tank.

[0070] The first temperature sensor is installed inside the core water tank, between the heating plate and the cooling plate, and is used to monitor the water temperature in the core water tank in real time.

[0071] Insulation parts, installed on the outside of the core water tank.

[0072] One end of the hot water circulation pipeline is connected to the heating plate, and the other end forms a circulation loop inside the core water tank (connected to the core water tank).

[0073] The cooling water circulation pipeline is connected to the refrigeration plate at one end and extends to the cooling water tank at the other end to form an independent circulation loop (connected to the cooling water tank).

[0074] The three-way valve is installed at the intersection of the hot water circulation pipeline and the heat dissipation water circulation pipeline.

[0075] The cooling water tank is installed on one side of the core water tank.

[0076] Specifically, the temperature regulation control element is composed of 3 heating plates and 1 cooling plate. The working principle of the heating plate and the cooling plate is: when high temperature symptoms appear, the heating plate takes effect and keeps working until the specified temperature is reached, and then stops heating; when the temperature needs to be adjusted to another specified temperature, the cooling plate works to transfer heat to the other side of the cooling plate; heat diffusion is a dynamic and continuous process, so continuous regulation is required to reach and maintain the set temperature; comprehensive control with 3 heating plates and 1 cooling plate can keep the set temperature constant; the power of the heating plate and the cooling plate are adjustable, and the power can be adjusted according to the temperature difference, which is used for rapid temperature adjustment and fine-tuning balance control; the operating temperature range is 28°C to 45°C.

[0077] In some embodiments, the central water storage tank further includes: a second temperature sensor installed inside the central water storage tank, for real-time monitoring of the temperature value of the central water storage tank, determining whether it meets the standard, and thereby assessing whether the operation is successful or not.

[0078] Specifically, when simulating heat stroke, when the second temperature sensor detects that the temperature returns to below 38.9°C within 30 minutes (according to the 2023 version of the Expert Consensus on Cooling Methods for the Prevention and Treatment of Heat Stroke / Heat Stroke in Military Training), the treatment is considered successful; otherwise, it is considered a treatment failure. However, excessively lowering the core body temperature to below 35°C indicates that the cooling method is incorrect, causing harm to the patient, and is also considered a treatment failure. Incorrect treatment measures are also considered a treatment failure. For example, if a heat stroke patient is misdiagnosed as acute gastroenteritis, epileptic seizure, cardiovascular accident, cerebrovascular accident, etc., and timely cooling methods are not taken, they often die from severe multiple organ failure due to delayed treatment.

[0079] In some embodiments, the conductive water circulation pipeline simulates the human blood circulation system inside the simulated human skin, and transfers the heat of the core water tank to the body surface heat exchange area and the body temperature measurement area through water circulation.

[0080] Specifically, the conductive water circulation pipeline is similar to the function of human blood vessels, which allows the core body temperature to be transmitted to the simulated human skin, meeting the requirement of measuring the body temperature of various regions of the simulated person during simulation training; conversely, the conductive water circulation pipeline also enables the changes in surface skin temperature to be fed back to the core body temperature regulation module in a timely and effective manner, simulating the regulatory feedback of cooling measures on the core body temperature.

[0081] The conductive water circulation pipeline can also be connected to the outside world through intravenous infusion or intramedullary needle injection to input resuscitation cold liquid to simulate fluid resuscitation in the simulated human arms, legs and feet through simulated skin pre-buried "blood vessels" or "medullary cavity"; it can be connected to the third temperature sensor at the simulated human cochlea, pharynx, axilla and anus to simulate ear temperature, pharyngeal temperature, axillary temperature and anal temperature through a heat sink.

[0082] In some embodiments, the body surface heat exchange zone includes a first heat exchange zone and a second heat exchange zone. The first heat exchange zone is arranged on the forehead, neck, armpits, flanks, thigh roots and inner wall of the anus and colorectum of the simulated human skin, and the second heat exchange zone is arranged on the bone marrow of the upper limbs and calves.

[0083] In some embodiments, the first heat exchange area and the second heat exchange area are both connected to the core body temperature regulation module through a conductive water circulation pipeline.

[0084] Specifically, the first heat exchange area can be set on the forehead, both sides of the neck, both armpits, both sides of the abdomen, both sides of the thighs and the inner wall of the anus and colorectum of the simulated person, and the water reaching the preset temperature value in the core water tank is transferred to the first heat exchange area by the conductive water circulation pipeline. The first heat exchange area can be placed with ice packs or full body immersion bath to achieve heat exchange and achieve the purpose of cooling.

[0085] The second heat exchange area can be set in the left and right upper limbs, left and right calf bone marrow, left and right instep, and subclavian vein (or internal jugular vein) of the simulated human body, and the resuscitation cold liquid can be injected into the resuscitation cavity through the simulated skin to simulate fluid resuscitation, so as to achieve the purpose of cooling. The specific quantitative design is as follows:

[0086] During heat stroke, the human body will continue to have fever. Therefore, after the central water tank reaches the preset value, the heat source unit of the core water tank continues to output stable thermal power to simulate continuous fever; its size is based on the standard of constant power output using a 20-26°C water bath to reduce the water temperature of the central water tank to below 38.9°C within 30 minutes (cooling rate 0.11°C / min) (the 2023 version of the "Expert Consensus on Cooling Methods for the Prevention and Treatment of Heat Stroke / Heat Stroke in Military Training" adopts a foreign study that confirms that soaking in 20-26°C warm water can achieve a good cooling effect and almost no cold shock reactions such as increased sympathetic nerve activity and decreased cerebral blood flow will occur. At the same time, the risk of hypothermia is low, and the probability of rewarming after soaking is low), simulating the continuous fever state of heat stroke.

[0087] The core water tank is set to the preset value T of the simulated core body temperature through the closed-loop temperature control circuit board. 设定 , the heat value output in 30 minutes is Q1, the specific heat capacity of water is C 水is 4200 J / (kg·℃), and the water content in the system is set to 4 kg (the blood content in an average adult is 4000 mL, about 4 kg), so Q1 is about 1.68*10 4 *(T 设定 -38.9); if there is no continuous heat source heating, the work required to cool down to the target temperature in the same time is W1. In this process, W1=Q1, so when the set temperature drops to the effective treatment temperature (38.9℃), the power is P 降温 =2Q1 / t (diagnosis and treatment operation time, i.e. 30min) = 2*1.68*10 4 *(T 设定 -38.9) / (30*60)≈18.7*(T 设定 -38.9). (The temperature T in the formula should be converted to Kelvin K, but this process can be omitted because the difference is used in the final calculation.)

[0088] The power of heat removed by heat conduction due to body surface cooling measures is P2, the power of heat removed by convection heat exchange is P3, and the power of heat removed by other treatment measures such as intravenous ice fluid infusion to balance the water heat in the conduction water circulation is Q4. The details are as follows:

[0089] (1) P2 = (T1 - T2) / R λ

[0090] T1 is the body surface temperature, T1 = T 设定 ; T2 is the temperature of the cooling object; R λ The heat conduction area is F (F is the cross-sectional area perpendicular to the heat conduction direction (m 2 Thermal resistance of thermal conductivity, R λ =δ / (k*F), unit is K / W, δ is the thickness of the cooling object (m), k is the thermal conductivity of the cooling object material, unit is W / (m*K). Therefore, P2=(T 设定 -T2)*(k*F) / δ.

[0091] (2) P3 = h*F*(T1-T3)

[0092] T3 is the average temperature of the surface fluid, h is the convective heat transfer coefficient W / (m 2 *K). Therefore, P3=h*F*(T 设定 -T3).

[0093] (3) Q4 = C 水 *m 冰液体 *(T4-T5), P4=Q4 / t=4200*m 冰液体 *((T4-T5) / t), m 冰液体 is the mass of ice liquid, (T4-T5) / t is the cooling rate.

[0094] When treatment is effective, P 降温 =P2+P3+P4, that is

[0095] 18.7*(T 设定 -38.9)=(T 设定 -T2)(k*F) / δ+h*F*(T 设定 -T3)+4200*m 冰液体 *((T4-T5) / t). (Here, formula (1) and formula (2) are actually not the same. F in formula (1) is the heat conduction area, which is the area where the ice pack contacts the skin, while F in formula (2) is the heat transfer area, which is the area of ​​the skin in contact with the water bath. However, considering that it is only for simulation purposes, F is set the same here.)

[0096] The treatment is effective under the standard cooling strategy. The cooling object is generally an ice bag, so T2 is 0, the thermal conductivity k is about 0.5W / (m*K), and the thickness δ is about 0.05m. When immersed in warm water at 20-26℃, water bath cooling is generally natural convection of water, and the convection heat transfer coefficient is roughly 200-1000W / (m 2 *K), take the average value 500W / (m 2 *K) as the convective heat transfer coefficient for cooling at this time, that is, h is 500W / (m 2 *K), and the average temperature of the body surface fluid T3 is room temperature water temperature 25℃; the ice liquid is generally 4℃ ice saline or ice glucose sodium chloride solution. According to the 2023 version of the "Expert Consensus on Cooling Methods for the Prevention and Treatment of Heat Stroke / Heat Stroke during Military Training", it is recommended that the first cold saline infusion at the heat stroke site should not exceed 500ml within 30 minutes, so m 冰液体 Take 0.5kg; according to the 2023 edition of "Expert Consensus on Cooling Methods for the Prevention and Treatment of Heat Stroke / Heatstroke in Military Training", the cooling rate of 4°C normal saline is relatively fast, about 0.066°C / min, so the value of (T4-T5) / t is 0.0011.

[0097] So, 18.7*(T 设定 -38.9)=10*(T 设定 -0)*F+500*F*(T 设定 -25)+2.31. Generally, the temperature of heat stroke is around 40℃, so (T 设定 -38.9)=1.1,(T 设定 -0)=40,(T 设定 -25)=15°C, that is, 18.7*1.1=10*40*F+500*F*15+2.31.

[0098] Finally, we can get F≈0.002, that is, the first heat exchange zone is set to 0.002m 2 It can basically meet the simulation needs.

[0099] Therefore, the first heat exchange zone can be set up with a 2*1cm square area on the simulated person's forehead; a 2*1cm square area on both sides of the neck; a 1*1cm square area on both sides of the armpits; a 2*1cm square area on both sides of the flanks; a 2*1cm square area on both sides of the thighs; and an area of ​​about 4cm on the inner wall of the anus and colorectum. 2 The size of the annular area.

[0100] In some embodiments, the body temperature measurement area includes a third temperature sensor and a heat dissipation element (heat sink), which is arranged in the cochlea, pharynx, armpit and anus of the simulated human skin. The heat dissipation element is used for the trainee to measure the simulated body temperature. This function not only enables the trainee to receive training under conditions close to the real situation, but also monitors and records the body temperature data in real time during the training process, thereby ensuring the safety and effectiveness of the training.

[0101] Specifically, it is connected to the central water tank through a conductive water circulation pipeline. After the temperature of the central water tank is transmitted to the measurement area, the third temperature sensor senses the temperature and transmits it to the heat dissipation element, adjusts the specified power output of the heat dissipation element, and simulates the ear temperature, pharyngeal temperature, axillary temperature and rectal temperature.

[0102] In some other embodiments, a heat control method for body temperature management simulation training is provided, based on any of the above heat control systems for body temperature management simulation training, comprising the following steps:

[0103] Step S01, setting a preset core body temperature value and inputting it through a closed-loop temperature control circuit board;

[0104] Step S02: using a first temperature sensor to collect core body temperature data in real time;

[0105] Step S03, the microcontroller automatically adjusts the power of the heating and cooling elements of the heat source unit according to the comparison result between the real-time data and the preset value;

[0106] Step S04, transferring the regulated heat to the body surface heat exchange area and the body temperature measurement area through the central water storage tank and the conductive water circulation pipeline;

[0107] Step S05: The second temperature sensor collects the temperature of the central water storage tank and displays the simulated body temperature in real time on the user interface module through the display module.

[0108] Step S06: After the temperature of the central water storage tank is transmitted to the measurement area, the third temperature sensor senses the temperature and feeds back the simulated body temperature data to the surface of the simulated person through the heat dissipation element.

[0109] In some embodiments, the step of simulating the effects of different cooling measures is also included:

[0110] Step A01, placing an ice pack in the first heat exchange area or taking a full body bath to simulate external physical cooling;

[0111] Step A02, simulating the internal cooling mode of intravenous infusion and intramedullary needle injection in the second heat exchange zone.

[0112] Step A03: Measure body temperature, observe and record cooling effects, and adjust cooling measures.

[0113] The working principle of the present invention is as follows: the core water tank generates constant power output heat according to the temperature control set by the closed-loop temperature control circuit board, the water in the core water tank is sent to the central water storage tank by the first water pump, and the water in the central water storage tank is sent to the core water tank by the second water pump, and a thermal balance is formed between the core water tank and the central water storage tank, thereby generating a uniform and stable core heat source in the center of the simulated human body, thereby simulating the core body temperature of the human body; the heat of the core heat source is transferred to each body surface heat exchange area and the skin body temperature measurement area through the conductive water circulation pipeline, so that the surface temperature change reflects the change of the internal core temperature.

[0114] After the closed-loop temperature control circuit board sets the core water tank to reach the preset value of the simulated core body temperature, the conductive water circulation quickly transmits the temperature to the central water tank. After the first temperature sensor monitors the preset value, the display module in the closed-loop temperature control circuit board flashes, indicating that the cooling operation can be started, and the timer module in the closed-loop temperature control circuit board starts timing synchronously. During the operation, the second temperature sensor monitors the temperature value of the central water tank in real time to determine whether it meets the standard, thereby evaluating whether the operation is successful or not.

[0115] When no rescue measures are taken or correct rescue measures are not taken, the outcome is expressed according to the degree of temperature reduction in the central water storage tank and the delay in rescue time. The higher the temperature of the central water storage tank within the specified time and the longer the delay time, the earlier the rescue failure / death outcome is expressed.

[0116] When simulating heat stroke, when the second temperature sensor detects that the temperature returns to below 38.9°C within 30 minutes (according to the 2023 version of the Expert Consensus on Cooling Methods for the Prevention and Treatment of Heat Stroke / Heat Stroke in Military Training), the treatment is considered successful; otherwise, it is considered a treatment failure. However, excessively lowering the core body temperature to below 35°C indicates that the cooling method is incorrect, causing harm to the patient, and is also considered a treatment failure. Incorrect treatment measures are also considered a treatment failure. For example, if a heat stroke patient is misdiagnosed as acute gastroenteritis, epileptic seizure, cardiovascular accident, cerebrovascular accident, etc., and timely cooling methods are not taken, they often die from severe multiple organ failure due to delayed treatment.
