Description

Technical Field

[0001] This invention relates to the field of outdoor rescue technology, and in particular to a field airdrop-type multi-parameter closed-loop rewarming and treatment system and its control method. Background Technology

[0002] In high-altitude, polar, deep-sea, or other extremely harsh field and emergency rescue environments, wounded personnel face an extremely high risk of hypothermia. Hypothermia not only directly impairs physiological functions but can also exacerbate and rapidly worsen critical complications such as high-altitude cerebral edema and high-altitude pulmonary edema (collectively known as acute mountain sickness), creating a deadly vicious cycle. The treatment window for such complex injuries is extremely short, placing almost stringent demands on the timeliness, accuracy, and continuity of on-site treatment.

[0003] For example, a ventilation and reheating device with publication number CN115813651A includes an air supply control unit, an air inflator, an air supply duct, and a return air duct. Electric heating wires are spirally arranged in the air supply duct and the return air duct. The entire system of this invention forms a ventilation and reheating device with a ventilation circuit, consisting of a blower, an air supply duct, an air supply component, an air inflator, and a return air duct. It can effectively utilize the heat of the return air, prevent heat loss, and greatly reduce the system energy consumption. The control module adjusts the power of the electric heating wire according to the temperature feedback from the temperature sensor, thereby controlling the effect of the reheating device. It has the characteristics of fast temperature rise and more accurate temperature control. For example, an assisted breathing rewarming device with the publication (announcement) number CN114602030A includes a humidification box, tubing, a humidification heater, an air outlet, a mask, a control board, and a power board. The humidifier can regulate the humidity of the air passing through, and the heater can heat the air passing through. A tubing temperature sensor is installed at the end of the tubing near the mask, and the collected temperature is closer to the temperature of human inhalation. This device can simultaneously control the temperature and humidity of inhalation to achieve the purpose of human rewarming. For example, an infusion heating device with publication number CN114602010A includes a housing, an infusion unit, a heating sleeve, an infusion heating control board, an infusion tube, and a power plug. The infusion heating control board includes an infusion control board and a heating control board. The heating sleeve is electrically connected to the heating control board, and the infusion unit is electrically connected to the infusion control board. The infusion tube passes through the infusion unit and the heating sleeve in sequence. This invention uses a heating sleeve fitted over the infusion tube. The controller controls the heating control power supply and adjusts the power of the heating wire according to the temperature detected by the temperature sensor in the heating sleeve, so that the infusion temperature is controlled at the set temperature value. For example, the rewarming system for treating hypothermia, published under announcement number CN120420147A, is designed with a ventilation and rewarming circulation channel: an air inlet connected to an insulated sleeping bag—an air inlet duct—an aerodynamic device—an air outlet connecting sleeve—a gas heating unit—an air guide adapter—an air outlet connected to the insulated sleeping bag, which can better realize the ventilation and rewarming function for hypothermic patients. A respiratory rewarming channel is also designed, with the heating channel consisting of: an oxygen supply inlet—a respiratory ventilation module—an internal respiratory heating module—an adapter—a respiratory heating interface—an external respiratory heating module—a breathing mask; and the humidification channel consisting of: a respiratory nebulization module—an adapter—a respiratory heating interface—an external respiratory heating module—a breathing mask, which can better realize the respiratory rewarming function for hypothermic patients. An infusion rewarming channel is also designed, consisting of: an infusion pump door—an infusion unit—a heating unit, which can better realize the infusion rewarming function for hypothermic patients. For example, the publicly disclosed portable field thermostatic frostbite rewarming device (CN221384000U) includes: a thermal suit shaped like a human torso, with observation and operation windows on its surface; a headgear fixed to one end of the thermal suit; a retractor at the other end of the thermal suit; an air cushion on the back of the thermal suit, with its end fixed to the retractor; and a heating system including an exhaust pipe and a connecting pipe. The exhaust pipe is located inside the air cushion, with an airflow monitoring device at one end and the other end extending into the retractor. The connecting pipe is located inside the thermal suit. This portable field thermostatic frostbite rewarming device, through its multi-structure design, allows for comprehensive wrapping of the injured person, enabling on-site rewarming treatment. It also features a simple overall structure, convenient operation, and easy portability.

[0004] However, the aforementioned traditional rescue systems face multiple bottlenecks in such scenarios: First, due to extreme terrain, severe weather, and transportation disruptions, ground rescue forces often struggle to arrive quickly, missing crucial rescue time. Second, existing emergency airdropped supplies are mostly simple, separate supplies such as food, medicine, and thermal blankets, lacking integrated treatment units with intelligent life support capabilities. Even with airdropped medical kits, the focus is often on static delivery of supplies, failing to address the systemic issues of "accessibility, deployment, usability, and accuracy of rescue." Specifically, regarding the rewarming treatment of patients suffering from hypothermia and altitude sickness, existing technologies and equipment are significantly inadequate. Rewarming methods are limited and inefficient: On-site operations often rely on passive insulation (such as thermal blankets) or simple chemical heating bags. These methods have low thermal efficiency, uncontrollable temperature, and short duration, making it impossible to combat heat loss in extreme environments and even more difficult to achieve safe, active, and rapid rewarming.

[0005] Isolated vital sign monitoring: Existing portable devices typically can only monitor a single physiological parameter (such as blood oxygen or body temperature), lacking simultaneous, continuous acquisition and fusion analysis of multiple parameters (such as EEG, cerebral oxygen saturation, respiratory rate, heart rate variability, etc.). This makes it impossible to provide early and accurate warnings of hidden dangers such as high-altitude cerebral edema and pulmonary edema, resulting in delayed intervention.

[0006] Treatment decisions rely heavily on human experience and lack closed-loop control: the rewarming process, oxygen supply flow rate, and medication administration depend heavily on the experience and judgment of on-site personnel. Under harsh environmental conditions and staff shortages, it is difficult to achieve dynamic and precise control based on real-time physiological feedback. Inappropriate rewarming rates (such as being too rapid) may induce rewarming shock, while improper timing and dosage of medication infusion can worsen the condition.

[0007] There is a "cold injury" blind spot in the intravenous infusion and oxygen supply process: In frigid environments, if the infused fluids and inhaled oxygen are not warmed, they will draw away a large amount of the patient's core heat, negating the rewarming effect and even causing secondary injuries such as vasospasm and bronchospasm. Existing systems generally neglect the dynamic warming of infusion lines and breathing gases throughout the entire process.

[0008] Lack of integrated "airdrop-deployment-decision" design: The existing solution fails to deeply integrate the impact-resistant airdrop structure, rapid automatic deployment, multi-parameter intelligent sensing, closed-loop constant temperature rewarming and remote communication, resulting in slow system deployment, complex operation and weak environmental adaptability, making it difficult to meet the actual combat requirements of "ready to use and operate autonomously" under field conditions.

[0009] In summary, there is an urgent need for an integrated treatment system that can be remotely and rapidly deployed, automatically deployed, integrate multi-parameter intelligent monitoring, and implement safe, precise, closed-loop constant temperature rewarming and targeted intervention for complications, in order to overcome the bottleneck of on-site treatment of critically injured patients in extreme environments. To this end, we propose a field airdrop-type multi-parameter closed-loop rewarming treatment system and control method. Summary of the Invention

[0010] The purpose of this invention is to provide a field airdrop-type multi-parameter closed-loop rewarming and treatment system and control method to solve the problems mentioned in the background art.

[0011] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A field-deployed, multi-parameter closed-loop rewarming and treatment system includes a rewarming box with a lid on top. The rewarming box consists of a first layer and a second layer. A protective cover is provided on one side of the first layer.

It then uses a heater and an infusion pump to reheat the body and administer intravenous fluids.

S4: If it is determined that there is a risk of hypothermia accompanied by altitude sickness, then based on step S3, the oxygen supply flow rate will be automatically adjusted according to the risk level, and the constant temperature liquid storage module will be controlled to deliver the corresponding emergency drugs.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1:

[0027] Reference Figure 1-8A field airdrop-type multi-parameter closed-loop rewarming treatment system includes a rewarming box 1, a box cover 2 on the top of the rewarming box 1, the rewarming box 1 is composed of a first box layer 3 and a second box layer 4, a protective cover 5 is provided on one side of the first box layer 3, and a pull-out operating table 30 is embedded in the top of the rewarming box 1 and the bottom of the box cover 2. The operating table 30 is a pull-out operating table, and after the operation is completed, the operating table can be pushed back to the top of the rewarming box 1. The operating table 30 is equipped with simple operating equipment such as a kidney dish and a sterile sheet, and can also be pushed back to the top of the rewarming chamber 1 along with the operating table 30; the inner side of the first chamber layer 3 is equipped with a rewarming mechanism, which includes a thermal garment 6, a first placement chamber 7, a heater 10 and a warm air pipe 11. The first placement chamber 7 is opened on the inner side of the first chamber layer 3. The heater 10 and the thermal garment 6 are placed inside the first placement chamber 7. The output end of the heater 10 is fixed with the warm air pipe 11, which is connected to the inner side of the thermal garment 6.

[0028] The inner side of the first compartment 3 is also equipped with an infusion mechanism for administering intravenous fluids to patients. The infusion mechanism includes a second placement chamber 8, a third placement chamber 9, an infusion pump 14, an infusion tubing 15, and an infusion bottle 18.

The infusion pump 14 is placed inside the third placement chamber 9, and the infusion tubing 15 is fixed to the output end of the infusion pump 14. The infusion tubing 15 is connected to the inner side of the thermal garment 6 and extends to the cuff of the thermal garment 6. The infusion bottle 18 is placed inside the second placement chamber 8. The medication is administered through the infusion tubing 15. Since part of the infusion tubing 15 is inside the second compartment 4 and the other part is inside the thermal garment 6, it can keep the medication warm and prevent freezing.

[0029] The thermal clothing 6 is equipped with a first double-ended zipper 12 and a second double-ended zipper 13. The top of the head area of ​​the thermal clothing 6 is equipped with a movable protective cover 17. The first double-ended zipper 12 and the second double-ended zipper 13 are both double-ended zippers that can be opened from the neck of the thermal clothing 6 to the little finger, which facilitates the operation and access of the head and hands.

[0030] The top of the thermal clothing 6 is evenly distributed with multiple operating windows 16, and the glove area of ​​the thermal clothing 6 is also provided with operating windows 16. The bottom of the thermal clothing 6 is provided with an inflatable cushioning back pad 19, which consists of a cushioning layer and a warm air layer from the outside to the inside. The inflatable cushioning back pad 19 can be inflated and unfolded. As warm air is injected, it expands when the pressure reaches a certain level, forming a cushioning layer. After the cushioning layer is fully inflated, the valve changes, and the upper layer of insulation is inflated. Air is supplied inside the garment 6; the inner side of the thermal garment 6 is equipped with an embedded infusion and heat preservation track, which is composed of a flexible heating layer 20 and a heat insulation layer 21, and is arranged along the torso to the arm. The embedded oxygen supply and heating track is integrated near the collar or mask of the thermal garment 6 to heat the gas delivered to the wounded and form a breathing rewarming channel; the periphery of the heat preservation window 16 is integrated with a ring heating plate and LED positioning light spot, which, together with the internal transparent guide film, is used to achieve rapid and accurate intravenous puncture in low temperature environment.

[0031] The inner side of the second layer 4 is equipped with a storage battery 24 and a control module 25. The storage battery 24 is electrically connected to the control module 25, the heater 10, and the infusion pump 14. The thermal clothing 6 is equipped with a body surface temperature sensor 22, which is electrically connected to the storage battery 24.

[0032] The inner side of the second compartment 4 is equipped with a camouflage mechanism for camouflaging the rewarming box 1. The camouflage mechanism includes telescopic rods 26, positioning rods 27, and camouflage nets 28. Two telescopic rods 26 are fixed on one side inside the second compartment 4, and two positioning rods 27 and camouflage nets 28 are placed at one end of the top of the second compartment 4. The telescopic rods 26 can be extended and shortened to facilitate the construction of camouflage nets 28 in conjunction with the positioning rods 27. The camouflage nets 28 have radar band stealth characteristics and play a role in security camouflage.

[0033] The four corners of the bottom of the rewarming chamber 1 are all fixed with buffer legs 29. When the rewarming chamber 1 touches the ground, the buffer legs 29 can absorb the impact and reduce the impact. Example 2:

[0034] A control method for a field air-dropped multi-parameter closed-loop rewarming and treatment system, applicable to such a system, includes the following steps: S1: After the re-incubator 1 is airdropped and deployed, the thermal clothing 6 is deployed; S2: The battery 24 determines the hypothermia level by fusion data and calculates the risk index of high-altitude cerebral edema or pulmonary edema based on multiple parameters, and performs rewarming and infusion through the heater 10 and the infusion pump 14. S3: If low body temperature is detected, the heater 10 dual-mode stepped rewarming mode is activated: the auxiliary rewarming mode is activated instantly for rapid preheating, while the main rewarming mode is activated for gradual temperature increase, and oxygen supply is automatically turned on according to the blood oxygen level. S4: If it is determined that there is a risk of hypothermia accompanied by altitude sickness, then based on step S3, the oxygen supply flow rate will be automatically adjusted according to the risk level, and the constant temperature liquid storage module will be controlled to deliver the corresponding emergency drugs. S5: Using EEG ratio, heart rate variability, respiratory rate and brain oxygen saturation as feedback, the battery dynamically adjusts the heating power and drug infusion rate to achieve closed-loop control. S6: All critical information is encrypted, packaged, and transmitted back to the rear in real time via the BeiDou link.

[0035] In summary: This invention addresses the technical problems faced by traditional rescue systems in such scenarios: First, due to extreme terrain, severe weather, and transportation disruptions, ground rescue forces often struggle to arrive quickly, missing crucial rescue time. Second, existing emergency airdropped supplies are mostly simple, separate supplies such as food, medicine, and thermal blankets, lacking integrated, intelligent life support units. Even with airdropped medical kits, the focus is often on static delivery, failing to address the systemic issues of "delivery accessibility, deployment effectiveness, usability, and accurate treatment." Specifically, existing technologies and equipment are significantly inadequate for rewarming patients suffering from hypothermia and altitude sickness. The invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows: During use, after unfolding the thermal garment 6, the patient enters the thermal garment 6 through the neck by unzipping the first double-ended zipper 12 and the second double-ended zipper 13. Then, the heater 10 is turned on, allowing warm air to flow through the warm air pipe 11 into the thermal garment 6 for rewarming. The patient's body temperature is then monitored by the body surface temperature sensor 22. When intravenous infusion is required, the corresponding infusion bottle 18 is retrieved from the second placement chamber 8, and then the infusion is administered through the infusion pump 14. The medication is infused through the infusion tubing 15. Since part of the infusion tubing 15 is located in the second compartment 4 and the other part is inside the thermal garment 6, the medication can be kept warm to prevent freezing. Finally, the two positioning rods 27 are removed, the camouflage net 28 is unfolded, and the telescopic rod 26 is extended to form four corner supports, allowing the camouflage net 28 to be erected and the thermal garment 6 below to be covered, thus camouflaging and protecting the rewarming box 1 and the box lid 2.

[0036] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects: 1. This invention utilizes comprehensive thermal management from multiple dimensions and angles, including body surface heating, respiration gas heating, infusion temperature control, and infusion tubing insulation, to ensure efficient, safe, and comfortable rewarming in extreme low-temperature environments and avoid secondary damage.

8. A field airdrop-type multi-parameter closed-loop rewarming and treatment system according to claim 1, characterized in that, The four corners of the bottom of the rewarming chamber (1) are all fixed with buffer legs (29).

9. A control method for a field airdrop-type multi-parameter closed-loop rewarming and treatment system, applicable to the field airdrop-type multi-parameter closed-loop rewarming and treatment system described in claims 1-8, characterized in that, Includes the following steps: S1: After the reheat box (1) is airdropped and deployed, the thermal clothing (6) is deployed; S2: The battery (24) determines the hypothermia level by fusion data and calculates the risk index of high-altitude cerebral edema or pulmonary edema based on multiple parameters, and performs rewarming and infusion through the heater (10) and infusion pump (14); S3: If the body temperature is determined to be low, start the heater (10) dual-mode step rewarming: instantly start the auxiliary rewarming mode for rapid preheating, and at the same time start the main rewarming mode for gradual temperature increase, and automatically start oxygen supply according to the blood oxygen level. S4: If the risk of hypothermia with altitude sickness is determined, then based on step S3, the oxygen supply flow rate will be automatically adjusted according to the risk level, and the constant temperature liquid storage module will be controlled to deliver the corresponding emergency drugs. S5: Using EEG ratio, heart rate variability, respiratory rate and brain oxygen saturation as feedback, the battery (24) dynamically adjusts the heating power and drug infusion rate to achieve closed-loop control; S6: All critical information is encrypted, packaged, and transmitted back to the rear in real time via the BeiDou link.
