Description
Technical Field
[0001] This invention relates to the field of therapeutic devices, and more specifically to a rapid rewarming and circulatory support system for frostbite and hypothermia at high altitudes. Background Technology
[0002] Currently, in high-altitude and frigid regions, the combined effects of cold and hypoxia impair blood circulation in skin tissues, potentially leading to frostbite. Frostbite further exacerbates this damage by increasing blood viscosity and hindering circulation, resulting in even more severe damage. Experiments have demonstrated that improved blood circulation positively impacts wound healing speed; therefore, restoring the vascular network is of paramount importance in the treatment of frostbite at high altitudes.
[0003] However, there are two main methods that can be used in the process of restoring blood circulation: one is to provide a constant temperature environment, and the other is to provide a low-frequency pulsed electromagnetic field. Most existing technologies use a single mode for processing. For example, the heating mode mostly uses a fixed preset temperature that cannot be adjusted, which has defects such as low rewarming efficiency and poor temperature control accuracy. If the heating speed is too fast and the temperature is fixed, it may cause secondary damage to the wound. Moreover, the two methods mentioned above are not combined, resulting in low processing efficiency.
[0004] Therefore, how to provide a rapid rewarming and circulation support system that can solve the above problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, the present invention provides a rapid rewarming and circulation support system for frostbite and hypothermia in high-altitude environments. It achieves dynamic temperature control, continuous protection, and intelligent decision-making for frostbite and hypothermia in high-altitude environments. Through modular design and closed-loop control logic, it solves the problems of low rewarming efficiency, poor temperature control accuracy, and lack of dynamic adaptability in traditional rewarming methods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rapid rewarming and circulatory support system for frostbite and hypothermia at high altitudes includes: The first temperature acquisition module is used to acquire the current first ambient temperature, the first frostbitten skin surface temperature, and the first skin surface image and perform preprocessing. The control module is connected to the first temperature acquisition module and is used to analyze the preprocessed first ambient temperature, the first frostbitten skin surface temperature and the first skin surface image to determine the corresponding first target temperature and the first target heating rate. A temperature regulation module, which is connected to the control module, is used to gradually increase the temperature to the optimal preset temperature according to the first target heating rate.
[0007] Preferred options also include: A heat preservation module, which is connected to the control module and the temperature regulation module, is used to preserve the temperature when it is raised to the optimal preset temperature.
[0008] Preferred options also include: The second temperature acquisition module is connected to the control module via the first drive switch. It is used to acquire the second ambient temperature, the second frostbitten skin surface temperature, and the second skin surface image again after the temperature is raised to the optimal preset temperature and a preset time period has elapsed, and then perform preprocessing.
[0009] Preferably, the control module includes: A receiving unit, which is connected to the first temperature acquisition module, is used to receive the preprocessed first ambient temperature, the first frostbitten skin surface temperature, and the first skin surface image. The model analysis unit is connected to the receiving unit and the temperature regulation module. It is used to construct a temperature analysis model. The pre-processed first ambient temperature, first frostbitten skin surface temperature and first skin surface image are input into the temperature analysis model for processing to obtain the corresponding first target temperature and first target heating rate. The model is then converted into control commands and sent to the temperature regulation module and the heat preservation module. A timing drive unit is connected to the first drive switch and the heat preservation module, and is used to control the first drive switch to start when the heat preservation module reaches a preset time. The comparison analysis unit is connected to the receiving unit, the timing drive unit, and the second temperature acquisition module. It is used to receive the preprocessed first ambient temperature, first frostbitten skin surface temperature and first skin surface image, second ambient temperature, second frostbitten skin surface temperature and second skin surface image, and perform comparison analysis to obtain the corresponding comparison results.
[0010] Preferably, the control module further includes: The first decision unit, connected to the comparison analysis unit, is used to construct a decision model when the comparison result does not meet the threshold requirement, and input the preprocessed second ambient temperature, second frostbitten skin surface temperature and second skin surface image into the decision model for processing to obtain the corresponding optimal adjustment scheme.
[0011] Preferably, the control module further includes: The second decision unit, connected to the comparison analysis unit and the model analysis unit, is used to control the model analysis unit to analyze and process the preprocessed second ambient temperature, second frostbitten skin surface temperature and second skin surface image when the comparison result meets the threshold requirement, to obtain the corresponding second target temperature and second target heating rate, and to generate corresponding control commands to be sent to the temperature adjustment module and the heat preservation module.
[0012] Preferred options also include: An electromagnetic pulse module, connected to the first decision unit, is used to determine whether an electromagnetic pulse module needs to be added for auxiliary processing based on the optimal adjustment scheme.
[0013] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a rapid rewarming and circulatory support system for frostbite and hypothermia at high altitudes, which has the following beneficial effects: 1. This invention, by setting up a dual temperature acquisition module, collects data that covers both macroscopic environmental factors and captures microscopic frostbite characteristics, avoiding misjudgments of rewarming schemes due to single data. After the temperature is raised to the optimal preset temperature and a preset time period has elapsed, the second temperature acquisition module is activated to capture the temperature rebound after rewarming in real time, forming a data closed loop of initial monitoring, rewarming, heat preservation, and secondary monitoring, providing a basis for subsequent scheme adjustments and avoiding the rebound of rewarming effect caused by lack of follow-up tracking after one rewarming. 2. This invention achieves precise temperature control through the coordinated use of a control module, a temperature regulation module, and a heat preservation module. It integrates and analyzes pre-processed ambient temperature, skin temperature, and skin image data to output differentiated solutions for different degrees of frostbite and different environmental conditions, thus solving the drawbacks of traditional fixed-rate heating. 3. This invention constructs an intelligent decision-making logic for data comparison and scheme adjustment by setting up a comparison analysis unit, a first and a second decision-making unit, thereby reducing the complexity of manual operation in high-altitude scenarios. When the comparison analysis unit determines that the comparison result between the second temperature data (after rewarming) and the first temperature data (initial) meets the threshold requirements, it makes differentiated decisions based on the comparison results to achieve continuous adaptation of heat preservation and fine-tuning. 4. The solution provided by this invention can avoid excessive heating, reduce reliance on manual labor, adapt to high-altitude emergency scenarios, eliminate the need for frequent intervention by operators, quickly respond to rewarming needs, and improve rescue efficiency; it also enhances system adaptability and scalability to meet the needs of multiple scenarios. Subsequently, based on the analysis results, the electromagnetic pulse module can be further activated to promote circulation through auxiliary treatment and improve the tissue recovery effect after rewarming.

[0017] See Figure 1 As shown, this embodiment of the invention discloses a rapid rewarming and circulatory support system for frostbite and hypothermia at high altitudes, comprising: The first temperature acquisition module 1 is used to acquire the current first ambient temperature, the first frostbitten skin surface temperature, and the first skin surface image and perform preprocessing. The preprocessing process may include temperature outlier removal, filtering, normalization, image filtering, enhancement, and normalization. Control module 2 is connected to the first temperature acquisition module 1 and is used to analyze the pre-processed first ambient temperature, the first frostbitten skin surface temperature and the first skin surface image to determine the corresponding first target temperature and the first target heating rate.

[0018] In one specific embodiment, it also includes: The heat preservation module 4 is connected to the control module 2 and the temperature regulation module 3, and is used to preserve the heat when the temperature rises to the optimal preset temperature.
[0019] In one specific embodiment, it also includes: The second temperature acquisition module 5 is connected to the control module 2 via the first drive switch 6. It is used to acquire the second ambient temperature, the second frostbitten skin surface temperature, and the second skin surface image again after the temperature is raised to the optimal preset temperature and after a preset time period, and to perform preprocessing. The preprocessing process can also include outlier removal, filtering, and normalization of temperature, as well as image filtering, enhancement, and normalization.
[0020] In one specific embodiment, the control module 2 includes: The receiving unit 21 is connected to the first temperature acquisition module 1 and is used to receive the pre-processed first ambient temperature, the first frostbitten skin surface temperature, and the first skin surface image. Model analysis unit 22 is connected to receiving unit 21 and temperature regulation module 3. It is used to construct temperature analysis model. The pre-processed first ambient temperature, first frostbitten skin surface temperature and first skin surface image are input into the temperature analysis model for processing to obtain the corresponding first target temperature and first target heating rate. The model is then converted into control commands and sent to temperature regulation module 3 and heat preservation module 4. The timing drive unit 23 is connected to the first drive switch 6 and the heat preservation module 4, and is used to control the first drive switch 6 to start when the heat preservation module 4 reaches a preset time. The comparison analysis unit 24 is connected to the receiving unit 21, the timing drive unit 23 and the second temperature acquisition module 5. It is used to receive the pre-processed first ambient temperature, the first frostbitten skin surface temperature and the first skin surface image, the second ambient temperature, the second frostbitten skin surface temperature and the second skin surface image, and perform comparison analysis to obtain the corresponding comparison results.
[0021] Specifically, the temperature analysis model can be a convolutional neural network with the activation function replaced by a wavelet basis function, which can better integrate multimodal feature data of temperature and image.
[0022] Specifically, the implementation process of the comparison and analysis unit 24 may include: Feature extraction is performed on the preprocessed first ambient temperature, first frostbite skin surface temperature and first skin surface image, second ambient temperature, second frostbite skin surface temperature and second skin surface image to obtain the corresponding first ambient temperature features, first frostbite skin surface temperature features and first skin surface image features, second ambient temperature features, second frostbite skin surface temperature features and second skin surface image features. Calculate the ambient temperature similarity between the first ambient temperature feature and the second ambient temperature feature, the skin surface temperature similarity between the first frostbite skin surface temperature feature and the second frostbite skin surface temperature feature, and the skin surface image similarity between the first skin surface image feature and the second skin surface image feature. When the similarity of ambient temperature, skin surface temperature, and skin surface image all fail to meet the corresponding threshold requirements, the system will directly output "failed to meet the threshold requirements" to the first decision unit 25; similarly, when all of them meet the corresponding threshold requirements, the system will directly output "meets the threshold requirements" to the second decision unit 26. When either the ambient temperature similarity or the skin surface temperature similarity does not meet the threshold requirement, but the skin surface image similarity meets the corresponding threshold requirement, the weights are assigned sequentially as 0.5 (for similarities that do not meet the threshold requirement), 0.3 (for similarities that meet the threshold requirement), and 0.2 (for similarities that meet the threshold requirement). The calculated result is then compared with the corresponding new threshold, and the corresponding comparison result is output.

It is used to construct a decision model when the comparison result does not meet the threshold requirement, and input the preprocessed second ambient temperature, second frostbite skin surface temperature and second skin surface image into the decision model for processing to obtain the corresponding optimal adjustment scheme. The decision model can be a decision tree model.
[0024] In one specific embodiment, the control module 2 further includes: The second decision unit 26 is connected to the comparison analysis unit 24 and the model analysis unit 22. When the comparison result meets the threshold requirement, the model analysis unit 22 is controlled to analyze and process the preprocessed second ambient temperature, second frostbitten skin surface temperature and second skin surface image to obtain the corresponding second target temperature and second target heating rate, and generate corresponding control commands to send to the temperature regulation module 3 and the heat preservation module 4.
[0025] In one specific embodiment, it also includes: Electromagnetic pulse module 7 is connected to the first decision unit 25 and is used to determine whether to add electromagnetic pulse module 7 for auxiliary processing according to the optimal adjustment scheme. Electromagnetic pulse module 7 may include a power supply, a signal source, a signal preprocessor, a power amplifier, a transmitting coil, and a regulator. The signal source is used to emit a low-frequency pulse signal. The regulator generates a signal with corresponding frequency, duty cycle, and amplitude according to the optimal adjustment scheme. After the signal is filtered to remove interference noise, it is amplified by the output power amplifier circuit, thereby finally driving the electromagnetic field transmitting coil to generate a suitable low-frequency pulse electromagnetic field.
