Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example 1 A device for heatstroke emergency treatment and hypothermia therapy, such as Figure 1 As shown, it includes cabin 1, composite cooling unit, and intelligent monitoring and control unit, the details of which are as follows: The cabin 1 adopts a transparent tent-like structure that can be quickly deployed and retracted. It is made of high-strength, flexible, transparent polyvinyl chloride film, which combines good transparency and tear resistance. This allows medical personnel to observe the injured person's condition from all angles, especially facial expressions, pupils, and any changes in neurological function such as convulsions or vomiting. The folding structure of cabin 1 is a conventional technique in existing technology; for example, the tent structure disclosed in publication number CN201495831U could be used. A door 101 is provided at one end of cabin 1. The edge of door 101 is connected to cabin 1 with a waterproof, sealed zipper, facilitating the movement of the injured person in and out while ensuring the airtightness of the cooling environment inside the cabin.

[0026] The composite cooling unit includes a contact conduction cooling module, a targeted cranial cooling module, and an environmental convection cooling module. The contact conduction cooling module uses a temperature-controllable ice blanket 2. The ice blanket 2 has a refrigerant circulation pipe 201 coiled inside, and the pipe is filled with refrigerant. Both ends of the refrigerant circulation pipe 201 pass through the side wall of the cabin 1 and are connected to the external refrigeration equipment 4. The target temperature can be set to achieve continuous and uniform conduction cooling of the back of the injured person. The targeted cranial hypothermia module uses a temperature-controlled ice cap 3 that is adapted to the head region of the injured person. The ice cap 3 is equipped with a cooling component, which can be a semiconductor cooling element connected to a central controller or a refrigerant circulation pipeline connected to a refrigeration device 4. The inner layer of the ice cap 3 is made of flexible silicone material, conforming to the contour of the head, and the temperature can be set to achieve independent and precise hypothermia treatment of the cranium. Ice blanket 2 can be attached to the bottom wall of cabin 1 via Velcro or directly fixed to the bottom wall of cabin 1; ice cap 3 can be placed directly on ice blanket 2, or attached to the upper surface of ice blanket 2 via Velcro, or directly fixed to ice blanket 2. The environmental convection cooling module includes a cold air inlet 102 located at the top of the cabin 1, an air outlet 103 at the bottom of the cabin 1, and a refrigeration device 4 connected to the cold air inlet 102. In this embodiment, the refrigeration device 4 adopts an existing air-cooled and water-cooled integrated machine. This device can output cold air and refrigerant simultaneously. It has a refrigerant outlet, a refrigerant inlet, and a cold air outlet on its side wall. An air supply pipe 401 is installed at the cold air outlet. The cold air inlet 102 at the top of the cabin 1 is connected to the refrigeration device 4 through the air supply pipe 401. The outlet air temperature and air volume of the refrigeration device 4 are adjustable. Multiple air outlets 103 are evenly arranged around the bottom of the cabin 1. After the refrigeration device 4 continuously pumps the cooled dry air into the cabin, it forms a cold air circulation from top to bottom. The heat from the surface of the injured person and the cabin environment is carried away by convection. It works in conjunction with the ice blanket 2 and the ice cap 3 to form a composite cooling mode of "conduction + convection + targeting".

[0027] The intelligent monitoring and control unit includes a vital signs monitoring module 6, a central controller, a display terminal 5, and a data recording and alarm system.

[0028] The vital signs monitoring module 6 can use contact or non-contact multi-parameter biosensors. In this embodiment, the vital signs monitoring module 6 is set on the inner wall of the cabin 1 near the chest or head. It integrates multiple sensors such as body temperature sensor, heart rate sensor, respiratory rate sensor, and blood oxygen sensor to monitor the core body temperature, heart rate, respiratory rate and blood oxygen saturation of the injured person. The vital signs monitoring module 6 adopts a non-invasive design to avoid causing additional damage to the injured person. The central controller and display terminal 5 are integrated on the control panel of the refrigeration equipment 4. The central controller uses an STM32 series microcontroller as the core control chip and has a built-in PID temperature control algorithm. The physiological parameters collected by the vital signs monitoring module 6 are transmitted to the central controller via a wireless Bluetooth module or a wired connection. The central controller displays the data on the display terminal 5 in real time. The display terminal 5 uses a touch screen, and medical staff can set the body temperature of the target patient and alarm thresholds for various parameters through the display screen. The data recording and alarm system is connected to the central controller and can record vital sign data throughout the entire treatment process, allowing users to set alarm thresholds for various parameters. It is equipped with an audible and visual alarm module; when abnormal parameters are detected, such as a rapid drop in body temperature, arrhythmia, or low blood oxygen, the central controller immediately activates the audible and visual alarm module to alert medical staff for timely intervention.

[0029] The method of using the device provided in this embodiment is as follows: After the device is delivered to the treatment site for heatstroke patients, medical personnel quickly deploy the chamber 1, ensuring it is placed stably. The heatstroke patient is then moved onto the ice blanket 2 inside the chamber and fitted with an ice cap 3. The chamber door 101 is closed. The cold air inlet 102 and refrigerant circulation pipeline 201 are connected to the refrigeration equipment 4, and the system is started. The refrigeration equipment 4 begins to deliver cold air into the chamber, creating a circulating airflow. Medical personnel set the target core body temperature (e.g., 39°C) and alarm thresholds for various parameters via the display terminal 5. The system then begins operating: the vital signs monitoring module 6 continuously monitors the patient's body temperature, heart rate, respiratory rate, blood oxygen saturation, and other parameters, transmitting the data in real-time to the central controller. The central controller automatically adjusts the cooling temperature of the ice blanket 2, the ice cap 3, and the outlet air temperature and volume based on the difference between the real-time core body temperature and the target body temperature, achieving closed-loop feedback temperature control until the patient's core body temperature stabilizes and remains within the target range. During this process, medical staff can continuously observe the injured person's facial expressions, pupil changes, and neurological function status such as convulsions and vomiting through the transparent cabin wall, while simultaneously viewing the vital signs data on the display terminal 5 in real time; the system automatically records all physiological parameters throughout the entire treatment process.

[0030] If abnormal parameters are detected (such as rapid drop in body temperature, arrhythmia, or low blood oxygen), the system will immediately issue an audible and visual alarm. Medical personnel must promptly open hatch 101 to provide targeted treatment to the injured person. After treatment, the hatch will be closed, and monitoring and treatment will continue until the injured person's condition stabilizes.

[0031] Example 2 A device for heatstroke emergency treatment and hypothermia therapy, such as Figure 2 As shown, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: a treatment port 104 and an air filter device 7 are added in this embodiment, as detailed below: The cabin 1 has a treatment port 104 on the side wall near the upper limb of the injured person. A treatment curtain 105 is installed at the treatment port 104. The top and sides of the treatment curtain 105 are connected to the treatment port 104 by zippers. The bottom of the treatment curtain 105 is fixedly connected to the treatment port 104. The treatment curtain 105 is designed to be folded down and opened, so as not to affect medical staff from reaching out to perform necessary medical operations such as intravenous puncture and examination of the condition.

[0032] An air filter 7 is installed at the cold air inlet 102, and both ends of the air filter 7 are detachably connected to the cold air inlet 102 and the air supply duct 401. Figure 3 As shown, the air filtration device 7 has an air inlet 701 and an air outlet 702 at both ends, which are connected to the air supply duct 401 and the cold air inlet 102 respectively via threads. Inside the air filtration device 7, from top to bottom, there are a pre-filter layer 703, an active oxygen sterilization layer 704, and a HEPA filter layer 705, which are used to filter the cold air entering the cabin 1.

[0033] The air filtration device 7 can perform multi-stage filtration of the cold air pumped into the cabin by the refrigeration equipment 4: the primary filter layer 703 intercepts large particulate impurities such as sand, fallen leaves, and hair in the air; the active oxygen sterilization layer 704 can kill pathogenic microorganisms such as bacteria and fungi in the air; and the HEPA filter layer 705 filters fine dust and aerosols with a diameter of 0.3μm or larger, preventing unclean air from entering the cabin 1 and coming into contact with the wounds on the surface of the injured person or being inhaled by the injured person, reducing the risk of secondary infection, especially suitable for injured persons with heatstroke combined with skin damage and impaired consciousness.

[0034] Meanwhile, a dustproof net is installed at the air outlet 103. After the cold air inside the cabin 1 circulates from top to bottom, it is discharged through the bottom air outlet 103. The dustproof net can intercept foreign objects such as dust, mosquitoes, and small stones from the outside environment, preventing them from flowing back into the cabin 1 with the airflow, contaminating the treatment environment inside the cabin, and preventing foreign objects from contacting the wounded and causing secondary injury.

[0035] In summary, the device provided by the present invention has the following significant beneficial effects: I. Highly efficient and coordinated cooling: It combines three physical cooling pathways—conduction, convection, and targeted cooling—to form a multi-dimensional heat exchange network. Compared to a single cooling method, it significantly improves the cooling rate and efficiency, and can reduce the core body temperature of the injured to a safe range in a short time, buying precious time to save lives.

[0036] II. Precise Target Management: The vital signs monitoring module monitors the core body temperature of the injured in real time and feeds the data back to the central controller. The central controller automatically or manually adjusts the working parameters of each cooling module, realizing the shift from experience-based cooling to data-driven precise temperature control. This effectively avoids the problems of insufficient cooling affecting the treatment effect or excessive cooling causing iatrogenic hypothermia injury.

[0037] Third, it emphasizes neuroprotection: The design of the special temperature-controlled ice cap can directly target the most critical damage target of heatstroke—the brain—to achieve regional hypothermia treatment of the cranium. Compared with traditional single cooling technology, the targeted hypothermia treatment of the cranium of this device can more accurately achieve neuroprotection, significantly reduce the brain metabolic rate, reduce cerebral edema and nerve damage, and improve the prognosis of the injured.

[0038] IV. Enhanced Safety: On the one hand, the transparent dry cooling environment completely avoids the risks of aspiration and suffocation caused by traditional cold water immersion; on the other hand, the transparent cabin allows medical staff to continuously observe the neurological function of the injured in 360°, and combined with real-time monitoring of vital signs, complications can be detected and treated early, greatly improving the safety of treatment.

[0039] V. High Integration and Portability: The three core functions of cooling, monitoring and brain protection are integrated into a lightweight and portable system. The cabin can be quickly deployed and stored. The overall equipment is easy to transport and deploy, and is particularly suitable for complex environments such as the field, battlefield and training ground where there are no fixed medical facilities, so as to achieve a rapid response of "treatment as soon as the cabin arrives".

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
