Description

Technology Field

[0001] The present invention relates to a detox technology using thermal energy, and more specifically, to a customized thermal detox technology based on body temperature. Background Technology

[0002] Thermotherapy, which utilizes heat to promote the elimination of waste products from the body and induce relaxation, has long been used in various forms. Recently, with the growing interest in wellness, it is becoming more widespread as a management program offered by specialized facilities. This type of thermotherapy can be operated by applying heat to the body for a set period to raise body temperature and induce sweating and increased blood flow, thereby expecting the elimination of waste products and recovery from fatigue.

[0003] However, conventional thermal management methods often remain limited to applying heat uniformly according to predetermined times and temperatures, which has limitations in that they do not adequately reflect the actual physical condition of the subjects receiving treatment. Even when applying heat of the same intensity, the rate at which body temperature rises and the extent to which it is reached can vary from subject to subject; if the output is fixed without considering these factors, it may result in excessive stimulation for some subjects while failing to provide sufficient effects for others.

[0004] Furthermore, since conventional methods often involved managers manually adjusting temperature and time based on experience, the quality of management depended on the manager's proficiency, making it difficult to guarantee consistent results for the same subjects every time. This can be a particular problem when operating multiple branches or providing standardized programs, and it can hinder the assurance of service reliability and reproducibility.

[0005] Meanwhile, as various sensor technologies for measuring a subject's physical condition have advanced, attempts are being made to measure body temperature or vital signs in real time and incorporate them into management. However, since these methods often remain limited to simply displaying or recording measured values, there have been quite a few instances where they have failed to evolve into an integrated control structure that automatically feeds measurement results back into the operation of heating devices to adjust output.

[0006] Accordingly, there is a need for a control method capable of consistently executing a series of processes that measure a subject's body temperature in real time, automatically adjust the output of the heating device based on the measurement results to reach and maintain a target temperature for a certain period, and then safely shut down. Furthermore, there is an emerging need for technology that can personalize the target temperature according to the subject's physical condition and type, while also considering the subject's safety during the management process.

[0022] In addition, by acquiring the subject's vital signs and controlling the output to reduce or stop it if the value exceeds a threshold, the subject's safety can be ensured during the management process. This reduces the risks associated with thermal management and provides an environment where the subject can receive treatment with peace of mind. Brief explanation of the drawing

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4.

[0027] FIG. 1 is a block diagram showing the components of an electronic device according to one embodiment of the present invention.

[0028] According to one embodiment, the electronic device (100) may include a memory (110), a processor (120), a communication interface (130), and / or a display device (140). The configuration of the electronic device (100) illustrated in FIG. 1 is exemplary and the embodiments of the present invention are not limited thereto. For example, the electronic device (100) may further include components not illustrated in FIG. 1 (e.g., a user interface, an input device, a notification unit, a sensor unit, or at least one of any combination thereof).

[0029] According to one embodiment, the memory (110) may store instructions or data. For example, the memory (110) may store one or more instructions that cause the electronic device (100) to perform various operations when executed by the processor (120).

[0030] For example, the memory (110) may be implemented as a single chipset with the processor (120). The processor (120) may include at least one of a communication processor or a modem.

[0031] For example, the memory (110) can store various information related to the electronic device (100). For example, the memory (110) can store information regarding the operation history of the processor (120). For example, the memory (110) can store input data acquired by the electronic device (100), output data output by the electronic device (100), data acquired from an external server, a wearable device, a plurality of cameras and / or user terminals, etc.

[0032] For example, the memory (110) may include multiple storage devices of different types. For example, the memory (110) may include volatile and / or non-volatile storage media. For example, the memory (110) may include at least one of RAM (random-access memory), ROM (read only memory), eMMC (Embedded Multi-Media Card), or any combination thereof.

[0033] The steps of the method or algorithm described in connection with the embodiments disclosed in this specification may be directly implemented in hardware, software modules, or a combination of both, executed by the processor (120). The software modules may reside in a storage medium (i.e., memory (110)) such as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, or a CD-ROM.

[0034] For example, the memory (110) is coupled to a processor (120), and the processor (120) can read information from a storage medium and write information to a storage medium. Alternatively, the memory (110) may be integrated with the processor (120). The memory (110) and the processor (120) may reside within an application-specific integrated circuit (ASIC). The ASIC may reside within a user terminal. Alternatively, the memory (110) and the processor (120) may reside as separate components within the user terminal.

[0035] According to one embodiment, the processor (120) may be operatively connected to the memory (110), the communication interface (130), and / or the display device (140). For example, the processor (120) may control the operation of the memory (110), the communication interface (130), and / or the display device (140).

[0036] According to one embodiment, the communication interface (130) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between an electronic device (100) and an external device (e.g., user terminal (210) of FIG. 2, external server (220), etc.), and the performance of communication through the established communication channel. The communication interface (130) may include one or more communication processors that operate independently of the processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication interface (130) may include a wireless communication module (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (e.g., LAN (local area network) communication module, or power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device through a first network (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a long-range communication network such as a computer network (e.g., LAN or WAN). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module can identify or authenticate the electronic device (100) within a communication network, such as the first network or the second network, using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in a subscriber identification module.

[0037] According to one embodiment, the display device (140) may include at least one output device that provides various information and a user interface to the user.

[0038] For example, the display device (140) may include a display device, an audio output device, a virtual reality output device, etc.

[0039] For example, the display device (140) can provide the user with various types of user interfaces described in the present disclosure visually and / or audibly.

[0040] The components of the electronic device (100) illustrated in FIG. 1 are exemplary and the embodiments of the present disclosure are not limited thereto.

[0041] At least some of the embodiments of the present disclosure may be implemented as artificial intelligence (AI) through a processor (120) and memory (110) of an electronic device (100). The processor (120) may be composed of one or more processors, and the one or more processors may be general-purpose processors such as a CPU, AP, DSP (digital signal processor), etc., graphics-dedicated processors such as a GPU, VPU (vision processing unit), or artificial intelligence-dedicated processors such as an NPU. The one or more processors may be controlled to process input data according to predefined operation rules or artificial intelligence models stored in memory (110). Alternatively, if the one or more processors are artificial intelligence-dedicated processors, the artificial intelligence-dedicated processors may be designed with a hardware structure specialized for processing a specific artificial intelligence model.

[0042] The predefined operation rules or artificial intelligence models are characterized by being created through learning. Here, being created through learning means that a predefined operation rules or artificial intelligence models configured to perform a desired characteristic (or purpose) are created by a basic artificial intelligence model being trained using a number of learning data by a learning algorithm. Such learning may be performed within the electronic device (100) itself where the artificial intelligence according to the present disclosure is performed, or it may be performed through a separate server and / or system. Examples of learning algorithms include supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but are not limited to the examples described above.

[0043] An artificial intelligence model may be composed of multiple neural network layers. Each of the multiple neural network layers has multiple weight values ​​and can perform neural network operations through operations between the results of previous layers and the multiple weights. The multiple weights possessed by the multiple neural network layers can be optimized based on the learning results of the artificial intelligence model. For example, the multiple weights can be updated so that the loss value or cost value obtained from the artificial intelligence model during the learning process is reduced or minimized. Artificial neural networks may include, but are not limited to, deep neural networks (DNN), convolutional neural networks (CNN), recurrent neural networks (RNN), restricted Boltzmann machines (RBM), deep belief networks (DBN), bidirectional recurrent deep neural networks (BRDNN), or deep Q-networks.

[0044] The processor of the electronic device (100) may utilize an artificial intelligence model to perform at least some operations of thermal detox management. An artificial intelligence model may refer to a model designed to learn certain rules or trends from input data and output a corresponding result when new data is input. The artificial intelligence model may be implemented in the form of an artificial neural network consisting of multiple layers, and may be implemented in at least one of various forms, such as a regression model, a classification model, or a recurrent neural network suitable for processing time-series data. The artificial intelligence model may be stored in the memory of the electronic device (100) and executed by the processor, or it may be provided on an external server (220) and utilized in a manner where the electronic device (100) receives the results.

[0045] The processor of the electronic device (100) can determine a target temperature or maintenance time suitable for the subject by utilizing an artificial intelligence model. For example, the processor can input information about the subject, such as the subject's reference temperature, body type information, age, or gender, into the artificial intelligence model and use the value output by the artificial intelligence model as the target temperature or maintenance time. In this case, the artificial intelligence model may be a model that has learned what target temperature and maintenance time were applied in what physical condition to multiple subjects and what reactions occurred as a result, and can output a value predicted to be suitable for a new subject based on the learned trends. Through this, a value that more broadly reflects the characteristics of the subject can be determined compared to the case where the target temperature is determined only by predetermined rules.

[0046] The processor of the electronic device (100) can control the output of the heating device by utilizing an artificial intelligence model. For example, the processor can input the pattern of change of the measured temperature obtained over time and the target temperature into the artificial intelligence model, and use the value output by the artificial intelligence model as the output of the heating device. This artificial intelligence model may be a model trained to predictively control the output by considering the trend of the measured temperature changing toward the target temperature, so that the body temperature does not reach the target temperature too quickly or significantly exceed the target temperature. Through this, compared to the case where the output is determined based only on the difference between the measured temperature and the target temperature, the output can be controlled according to the individual pattern of change of the subject's body temperature.

[0047] The processor of the electronic device (100) can determine the physical condition of the subject by utilizing an artificial intelligence model. For example, the processor can input biosignals obtained from a biosensor into the artificial intelligence model and use the value output by the artificial intelligence model as the subject's condition value or as a basis for determining whether an excessive burden has occurred to the subject. In this case, the artificial intelligence model may be a model that has learned the relationship between biosignals measured for multiple subjects and their physical condition at that time, and can estimate and output the degree of burden on the subject from the input biosignals. Through this, a more sophisticated safety judgment can be made by comprehensively considering multiple biosignals, compared to the case where biosignals are compared to a single reference value.

[0048] The processor of the electronic device (100) can update or refine correction values ​​corresponding to body types by utilizing an artificial intelligence model. For example, an artificial intelligence model provided on an external server (220) can be configured to learn the accumulated reference temperature, body type information, applied target temperature, and resulting changes in body temperature for multiple subjects, and to output which correction value is appropriate to apply to each body type. The electronic device (100) can receive the updated correction values ​​from the external server (220) and use them to determine the target temperature. Through this, as management accumulates, the correction values ​​for each body type become progressively more refined, thereby improving the personalization of the target temperature.

[0049] An artificial intelligence model used in an electronic device (100) can be prepared through a learning process. Learning an artificial intelligence model may refer to a process of repeatedly adjusting the internal parameters of the artificial intelligence model so that the difference between the output value and the predetermined correct answer is reduced by inputting multiple training data into the artificial intelligence model. For example, an artificial intelligence model for determining a target temperature can be trained using physical information of multiple subjects and target temperatures evaluated as suitable for them as training data, and an artificial intelligence model used for controlling output can be trained using the pattern of change in the measured temperature and the output that was suitable for it as training data. The training can be performed on an external server (220), and the artificial intelligence model that has completed training can be provided to the electronic device (100) for use.

[0050] Even when an AI model is utilized in this manner, the model may serve as a means to perform individual operations, such as determining target temperatures, regulating output, assessing physical conditions, and updating correction values. The values ​​output by the AI ​​model may be used to replace or supplement values ​​calculated according to predetermined rules. Furthermore, if the value output by the AI ​​model falls outside a pre-set allowable range, the processor may not apply the model's output as is, but instead correct it according to predetermined standards or replace it with a value that prioritizes safety. Through this approach, both management stability and safety can be ensured while utilizing the AI ​​model.

[0051] FIG. 2 is a block diagram showing the components of a system in which a customized thermal detox method using closed-loop feedback control based on body temperature is performed according to one embodiment of the present invention.

[0052] According to one embodiment, a system for performing a customized thermal detox method using closed-loop feedback control based on body temperature may include an electronic device (100), a user terminal (210), and an external server (220).

[0053] The electronic device (100) acts as the entity controlling the overall operation of thermal detox management and can be implemented as various types of computing devices including a processor and memory. For example, it can be implemented as a dedicated control device installed in a management facility, a general-purpose computer, a server, or an embedded control module built into a thermal device, and its physical form is not limited to a specific one. The electronic device (100) may be implemented as a single device or in a distributed form in which multiple devices operate in cooperation.

[0054] The processor of the electronic device (100) can perform a series of operations required for thermal detox management by executing one or more instructions stored in memory. The processor may be configured to include at least one of various processing units capable of performing operations, such as a central processing unit, a microprocessor, an application processor, or a hardware accelerator specialized for specific operations. The memory may store instructions executed by the processor and various information required for management, and may be implemented to include at least one of volatile memory and non-volatile memory.

[0055] The electronic device (100) is connected via wired or wireless connection to a heating device, temperature sensor, biosensor, ventilation device, etc., provided in the space where the subject is located, and can receive measurement results from these devices or transmit signals to control the operation of these devices. For example, the electronic device (100) can receive a measurement temperature corresponding to the subject's body temperature from a temperature sensor and transmit a control signal calculated based on the measurement result to the heating device so that the output of the heating device is adjusted.

[0056] The electronic device (100) may include a communication circuit for communicating with an external server (220) and a user terminal (210). The communication circuit may support at least one of wired communication and wireless communication, and may exchange data with external components through at least one of various communication methods, such as short-range wireless communication, mobile communication, or a wired network. Through such communication, the electronic device (100) may receive information necessary for management from the outside or transmit information regarding management results to the outside.

[0057] At least some of the operations performed by the electronic device (100) may be implemented to be performed on an external server (220) according to the embodiment. For example, operations requiring relatively large computational resources, such as operations to determine a target temperature or operations to analyze biosignals, may be performed on the external server (220), and the electronic device (100) may receive the results and use them to control the heating device. Through such a configuration in which operations are shared between the electronic device (100) and the external server (220), sophisticated management can be performed while reducing the computational burden on the electronic device (100).

[0058] The user terminal (210) is a terminal that is carried or operated by a subject or manager and can be implemented as a device of various forms capable of communicating with an electronic device (100) to input information necessary for management or to receive information regarding management. For example, the user terminal (210) can be implemented as a smartphone, tablet, wearable device, or a terminal in the form of a kiosk provided in a management facility, and its form is not limited to a specific type.

[0059] The user terminal (210) can receive information regarding the subject and transmit it to an electronic device (100) or an external server (220). For example, if the subject inputs information such as their body type, preferred intensity of care, or care history through the user terminal (210), the user terminal (210) can transmit the input information to the electronic device (100) or an external server (220) via communication so that it is reflected in the care. Such information input can be performed through an application program or a web interface installed on the user terminal (210).

[0060] The user terminal (210) can provide information regarding the progress or results of the management to the subject or manager. For example, the current body temperature being measured, the degree to which the target temperature has been reached, the remaining maintenance time, or information indicating that the management has ended can be displayed on the screen of the user terminal (210) or output in the form of a notification. Through this, the subject can intuitively understand the progress of the management they are receiving.

[0061] The user terminal (210) may provide a summary of the management results to the subject after the management is completed, or provide a function to view the accumulated management history. For example, by organizing and displaying information such as changes in body temperature measured over multiple management sessions or the time spent on management, the subject may be able to continuously check the progress of their management. This history information may be stored on an external server (220) and provided upon request from the user terminal (210).

[0062] The user terminal (210) may also be used by an administrator to monitor the management process or change settings. For example, it may be implemented so that an administrator can perform operations such as setting a target temperature or maintenance time for a specific subject through the user terminal (210), remotely checking the status of ongoing management, and stopping management if necessary. In this way, the user terminal (210) can provide input and output means related to management to both the subject and the administrator.

[0063] The external server (220) is a device that communicates with the electronic device (100) and the user terminal (210) to store information necessary for management or perform calculations, and may be implemented as one or more server computers. The external server (220) may be implemented as a single physical server, or as a form in which multiple servers are interconnected, or as a cloud-based virtualized server, and the form of implementation is not limited to a specific one.

[0064] The external server (220) may include or be connected to a database that stores and manages various information necessary for management. For example, information on the body type of each subject, correction values ​​corresponding to the body type, setting information regarding the target temperature and maintenance time, or accumulated management history may be stored in the external server (220). The external server (220) may provide the stored information or receive and update newly generated information in response to a request from the electronic device (100) or user terminal (210).

[0065] An external server (220) can perform operations requiring relatively large computational resources on behalf of the electronic device (100). For example, the external server (220) can perform operations such as calculating a target temperature based on the subject's reference temperature and body type information, or calculating the subject's state value by analyzing biosignals, and transmit the results to the electronic device (100). Through this configuration, the computational burden of the electronic device (100) can be distributed.

[0066] The external server (220) is connected to multiple electronic devices (100) and can manage information generated at multiple management points in an integrated manner. For example, it can collect and store management results from electronic devices (100) installed at various points, analyze them, and use them to check the quality of management or standardize settings. In this way, the external server (220) can function as a central information processing entity to consistently operate a distributed management environment.

[0067] The external server (220) can be used to analyze accumulated management history and improve management settings. For example, by analyzing the patterns of change in body temperature or management results accumulated for multiple subjects, the correction values ​​or target temperature settings for each body type can be updated and provided to the electronic device (100), thereby gradually improving the precision of management. Statistical techniques or machine learning-based techniques may be utilized for this analysis, and the results of the analysis may be reflected in subsequent management.

[0069] According to one embodiment, components of a system in which a customized thermal detox method using closed-loop feedback control based on body temperature is performed may perform the operations disclosed in FIG. 3. For example, among the components included in the electronic device (100) among the components of the system in which a customized thermal detox method using closed-loop feedback control based on body temperature is performed (e.g., memory (110), processor (120), communication interface (130), and display device (140) of FIG. 1), at least some of the components included in FIG. 1 may be configured to perform the operations of FIG. 3.

[0070] In the following embodiments, the operations S310 to S360 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. Additionally, content corresponding to or overlapping with the above description in relation to FIG. 3 may be briefly explained or omitted.

[0071] According to one embodiment, the processor (120) can obtain detox information including a target temperature set for the subject and a maintenance time during which the target temperature must be maintained (S310).

[0072] The processor of the electronic device (100) can obtain detox information including a target temperature set for the subject and a maintenance time during which the target temperature must be maintained. Detox information is information that serves as a standard for thermal detox management to be provided to the subject, and may include a target temperature corresponding to a target value of body temperature to be reached during the management process, and a maintenance time indicating how long the temperature will be maintained after reaching the target temperature. For example, the target temperature may be set to a value that the subject's body temperature must reach, such as 38 degrees Celsius, and the maintenance time may be set to a time during which the target temperature must be maintained, such as 20 minutes.

[0073] The method by which the processor obtains detox information can be implemented in various ways. For example, the processor may obtain detox information by receiving the target temperature and maintenance time entered by the manager or subject through the user terminal (210) via a communication circuit. As another example, when one of the management programs stored in advance in the memory of the electronic device (100) is selected, the processor may obtain detox information by reading the predetermined target temperature and maintenance time from the memory corresponding to the selected management program. As yet another example, the processor may obtain detox information by receiving subject-specific setting information stored in an external server (220) via communication.

[0074] Detox information may include additional information necessary for management, in addition to the target temperature and maintenance time. For example, detox information may include the maximum allowable heating time until the target temperature is reached, the upper limit of the output to be applied during management, or identification information to identify the subject. Through the action of acquiring detox information in this manner, it can be determined according to what criteria the subsequent series of actions—from output control and temperature maintenance to termination—will be performed, and the overall goals of management can be established.

[0075] According to one embodiment, the processor (120) can control the operation of a heating device provided in a space where the subject is located (S320).

[0076] The processor of the electronic device (100) can control the operation of a heating device provided in the space where the subject is located. A heating device is a device that raises the body temperature by applying heat to the space where the subject is located or to the subject's body, and can be implemented as various types of devices that generate heat using a heating element. For example, the heating device can be implemented as a heating panel that emits infrared or far-infrared rays, a heating bed with built-in heating wires, a heating device that supplies warm air, or a device that circulates a heated medium, and the implementation form is not limited to a specific one.

[0077] The method by which the processor controls the heating device can vary depending on the implementation form of the heating device. For example, the processor may transmit a control signal instructing the heating device to start operation, thereby causing the heating device to start heating, and the control signal may include information regarding the magnitude of the initial output. The heating device may be connected to the electronic device (100) via a wired or wireless connection to receive the control signal transmitted by the processor, and may start heating or adjust the magnitude of the output according to the received control signal.

[0078] As an example of a scenario in which a heating device initiates operation, when the initiation of treatment is determined while a subject is located in a space equipped with a heating device for treatment, the processor transmits a control signal instructing the heating device to initiate operation, and the heating device may begin heating in accordance with the control signal to apply heat to the space where the subject is located or to the subject's body. Through this operation of controlling the heating device to operate, heating can be initiated to raise the subject's body temperature toward a target temperature.

[0079] According to one embodiment, the processor (120) can obtain a measured temperature corresponding to the subject's body temperature from a temperature sensor (S330).

[0080] The processor of the electronic device (100) can obtain a measured temperature corresponding to the subject's body temperature from a temperature sensor. A temperature sensor is a device that measures the subject's body temperature or a value corresponding to the body temperature and outputs it as an electrical signal, and can be implemented as various types of sensors that measure temperature in a contact or non-contact manner with respect to the subject's body. For example, the temperature sensor can be implemented as a contact-type temperature sensor attached to the subject's skin, a non-contact infrared temperature sensor that detects infrared radiation emitted from the subject's body, or a temperature sensor embedded in a wearable device.

[0081] The measured temperature refers to a value corresponding to the subject's body temperature measured by a temperature sensor, and may include the subject's surface temperature, an estimated value corresponding to core body temperature, or a temperature measured at a specific part of the body. The processor can repeatedly acquire the measured temperature from the temperature sensor at regular time intervals; for example, it can receive the measured temperature at intervals of a few seconds or tens of seconds to continuously monitor changes in the subject's body temperature. The frequency of acquiring the measured temperature can be set in various ways depending on the characteristics of the management or the performance of the temperature sensor.

[0082] As an example of a scenario in which a processor acquires a measured temperature, while the subject's body temperature gradually rises after the heating device begins operation, the processor receives the measured temperature from the temperature sensor at regular intervals to determine how high the body temperature has risen. The processor can use this acquired measured temperature as a reference for comparison with the target temperature during subsequent output control or temperature maintenance operations. Through this operation of acquiring the measured temperature, the subject's actual body temperature can be determined in real time, enabling closed-loop control.

[0083] According to one embodiment, the processor (120) can adjust the output of the heating device based on the difference between the measured temperature and the target temperature (S340).

[0084] The processor of the electronic device (100) can adjust the output of the heating device based on the difference between the measured temperature and the target temperature. The output is a value corresponding to the magnitude of heat generated by the heating device per unit time, and can be expressed as the magnitude of power applied to the heating device, the temperature of the heating element, or the intensity of the hot air. The processor compares the previously obtained measured temperature with the target temperature included in the detox information to calculate the difference between the two, and can increase, decrease, or maintain the output of the heating device based on the calculated difference.

[0085] The way a processor regulates output can be implemented in various ways. For example, if the measured temperature is lower than the target temperature, the processor can control the output of the heating device to increase in order to raise the subject's body temperature toward the target temperature. Conversely, if the measured temperature approaches or exceeds the target temperature, the processor can control the output of the heating device to decrease in order to prevent the body temperature from rising excessively. In this case, the implementation can be designed so that the magnitude of the increase or decrease in output is set to be greater the greater the difference between the measured temperature and the target temperature.

[0086] As an example of a scenario where the processor regulates output, since the measured temperature is significantly lower than the target temperature at the beginning of treatment, the processor can set the output of the heating device relatively high to rapidly raise the body temperature, and then gradually lower the output as the measured temperature approaches the target temperature to prevent the body temperature from significantly exceeding the target temperature. Through this operation of regulating output based on the difference between the measured temperature and the target temperature, the subject's body temperature can be controlled to converge stably toward the target temperature.

[0087] According to one embodiment, the processor (120) can control the output of the heating device so that the measured temperature is maintained at the target temperature from the time the measured temperature reaches the target temperature until the maintenance time elapses (S350).

[0088] The processor of the electronic device (100) can control the output of the heating device so that the measured temperature is maintained at the target temperature from the time the measured temperature reaches the target temperature until the maintenance time elapses. The processor can determine whether the previously obtained measured temperature has reached the target temperature, and if it is determined that the measured temperature has reached the target temperature, it can start measuring the elapsed maintenance time based on that point in time. Whether the measured temperature has reached the target temperature can be determined based on whether the measured temperature becomes equal to the target temperature or falls within a certain range including the target temperature.

[0089] The method by which the processor maintains the measured temperature at the target temperature can be implemented by adjusting the output in response to fluctuations in the measured temperature. For example, if the measured temperature drops below the target temperature during the maintenance period, the processor can increase the output of the heating device to raise the body temperature back to the target temperature, and if the measured temperature rises above the target temperature, it can decrease the output to bring the body temperature back to the target temperature. By continuously adjusting the output in response to fluctuations in the measured temperature in this way, the measured temperature can be stably maintained near the target temperature.

[0090] As an example of a scenario in which the processor maintains the measured temperature at the target temperature, from the moment the subject's body temperature reaches the target temperature of 38 degrees Celsius, the processor begins measuring the elapsed time of 20 minutes, which is the maintenance time, and can finely adjust the output of the heating device so that the measured temperature is maintained around 38 degrees Celsius during those 20 minutes. Through this operation of controlling the output to maintain the measured temperature at the target temperature, the subject's body temperature is kept constant during the critical period of care, thereby providing a stable thermal state for a sufficient amount of time.

[0091] According to one embodiment, the processor (120) can control the output of the heating device to decrease as the maintenance time elapses (S360).

[0092] The processor of the electronic device (100) can control the output of the heating device to decrease as the maintenance time elapses. The processor can determine whether the measured time from the point when the measured temperature reaches the target temperature has reached the maintenance time included in the detox information, and if it is determined that the measured time has reached the maintenance time, it can transmit a control signal to decrease the output of the heating device. Controlling to decrease the output may mean lowering the power applied to the heating device or the temperature of the heating element, or stopping the heating of the heating device.

[0093] The method by which the processor reduces output can be implemented in various ways. For example, the processor can immediately reduce the output of the heating device to zero to stop the heating process once the maintenance time has elapsed, or, as another example, reduce the output in stages to allow the subject's body temperature to gradually decrease. In the case of reducing the output in stages, the subject's body is prevented from being exposed to sudden temperature changes, allowing the treatment to conclude more smoothly.

[0094] As an example of a scenario in which the processor reduces output, once the 20-minute maintenance time has elapsed from the moment the measured temperature reaches the target temperature, the processor can gradually lower the output of the heating device to allow the subject's body temperature to naturally begin to decrease. By controlling the output to decrease as the maintenance time elapses in this manner, the series of thermal detox management procedures, which involve reaching and maintaining the target temperature, can be safely and smoothly terminated.

[0095] FIG. 4 is a specific flowchart of the operation included in a customized thermal detox method using closed-loop feedback control based on body temperature according to one embodiment of the present invention.

[0096] According to one embodiment, components of a system in which a customized thermal detox method using closed-loop feedback control based on body temperature is performed may perform the operations disclosed in FIG. 4. For example, among the components included in the electronic device (100) among the components of the system in which a customized thermal detox method using closed-loop feedback control based on body temperature is performed (e.g., memory (110), processor (120), communication interface (130), and display device (140) of FIG. 1), at least some of the components included in FIG. 4 may be configured to perform the operations of FIG. 4.

[0097] In the following embodiments, the operations of S410 to S440 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. Additionally, content corresponding to or overlapping with the above description in relation to FIG. 4 may be briefly explained or omitted.

[0098] According to one embodiment, the processor (120) can calculate the difference between the measured temperature and the target temperature (S410).

[0099] The processor of the electronic device (100) can calculate the difference between the measured temperature and the target temperature. The difference is a value indicating how far the measured temperature, corresponding to the subject's body temperature, is from the target temperature to be reached, and can be calculated as the value obtained by subtracting the measured temperature from the target temperature or as the magnitude of the difference between the two values. For example, if the target temperature is 38 degrees Celsius and the measured temperature is 36 degrees Celsius, the difference can be calculated as a value corresponding to 2 degrees Celsius, and this value can indicate the degree of additional temperature increase required to raise the body temperature to the target temperature.

[0100] The processor can calculate the difference repeatedly whenever a measured temperature is acquired. For example, the processor can acquire the measured temperature from a temperature sensor at regular intervals and, each time the temperature is acquired, recalculate the difference between that measured temperature and the target temperature to continuously update how close the body temperature is to the target temperature. The difference may be calculated as a signed value that distinguishes between cases where the measured temperature is lower or higher than the target temperature, or as a magnitude value indicating only the degree of deviation, regardless of the sign.

[0101] As an example of a scenario in which the processor calculates a difference, while a heating device is operating and the subject's body temperature gradually rises, the processor calculates the difference between the target temperature of 38 degrees Celsius and the measured temperature at each measurement point. This allows the processor to identify a pattern where the difference, which is calculated as a large value at the beginning of management, gradually decreases over time. The processor can use this calculated difference as the basis for subsequent threshold range determination and output adjustment. Through this operation of calculating the difference, a quantitative value serving as the basis for output adjustment can be secured.

[0102] According to one embodiment, the processor (120) can determine whether the calculated difference is within a preset threshold range (S420).

[0103] The processor of the electronic device (100) can determine whether the calculated difference is within a preset threshold range. The threshold range is a range that serves as a standard for determining whether the measured temperature can be considered to have substantially reached the target temperature, and may be preset as a certain allowable range based on the target temperature and stored in the memory of the electronic device (100). For example, the threshold range may be set to a range corresponding to 0.5 degrees Celsius above and below the target temperature, and in this case, if the difference is within 0.5 degrees Celsius, the measured temperature can be considered to have substantially reached the target temperature.

[0104] The reason for establishing a threshold range is that if the standard were based solely on cases where the measured temperature exactly matches the target temperature, the output could change excessively frequently due to minute fluctuations in the measurement value. By setting a threshold range, the processor can maintain the output without changing it during the range where the measured temperature is sufficiently close to the target temperature, thereby ensuring stable control. The width of the threshold range can be set differently depending on the management characteristics or the measurement precision of the temperature sensor, and it may also be configured differently for each target or management program.

[0105] As an example of a scenario in which the processor determines whether it is within a threshold range, the processor compares the difference calculated at each measurement point with a preset threshold range to determine whether the magnitude of the calculated difference is within 0.5 degrees Celsius, which corresponds to the threshold range, or whether it exceeds it. Based on the result of this determination, the processor can decide whether to perform proportional control or maintain the output thereafter. Through this operation of determining whether the difference is within the threshold range, it is possible to distinguish whether the body temperature has substantially reached the target temperature and to perform output control accordingly.

[0106] According to one embodiment, if the difference calculated by the processor (120) exceeds a preset threshold range, the output of the heating device can be adjusted so that the output is set to be larger as the difference calculated is larger (S430).

[0107] The processor of the electronic device (100) can adjust the output so that when the calculated difference exceeds a preset threshold range, the output of the heating device is set to be larger as the calculated difference increases. This may be intended to heat with a larger output to rapidly raise the body temperature as the measured temperature is farther from the target temperature, and to gradually lower the output as the measured temperature approaches the target temperature so that the body temperature does not significantly exceed the target temperature. In other words, the output can be adjusted in a proportional relationship determined in correspondence with the magnitude of the difference.

[0108] The method by which the processor adjusts the output based on the magnitude of the difference can be implemented in various ways. For example, the processor can calculate an output that increases continuously in proportion to the magnitude of the difference; in this case, if the difference doubles, the increment added to the base output can be set to approximately double as well. As another example, the processor can divide the magnitude of the difference into multiple intervals and predetermine the magnitude of the output corresponding to each interval, thereby controlling the heating device with the output corresponding to the interval to which the calculated difference belongs. The specific relationship for calculating the output corresponding to the magnitude of the difference may also be implemented in the form of a mathematical formula described separately.

[0109] As an example of a scenario where the processor adjusts the output based on the magnitude of the difference, if the measured temperature is 2 degrees Celsius lower than the target temperature at the beginning of management, the processor controls the heating device with a relatively large output to rapidly raise the body temperature; if the body temperature rises and the difference decreases to 1 degree Celsius, the output is lowered accordingly; and if the difference decreases further, the output is lowered even more so that the body temperature converges gradually to the target temperature. In this way, by adjusting the output so that it is set higher as the difference increases when the difference exceeds a critical range, the body temperature can be controlled to converge toward the target temperature quickly and stably.

[0110] According to one embodiment, the processor (120) can control the output of the heating device to be maintained when the calculated difference is within a preset threshold range (S440).

[0111] The processor of the electronic device (100) can control the output of the heating device to be maintained when the calculated difference is within a preset threshold range. Controlling the output to be maintained means that the magnitude of the output applied to the heating device at that time is not changed and is maintained as is, assuming that the measured temperature has substantially reached the target temperature. This may be intended to ensure that the body temperature is maintained stably near the target temperature by not unnecessarily changing the output in the range where the body temperature is sufficiently close to the target temperature.

[0112] The method by which the processor maintains the output can be implemented by continuously monitoring whether the measured temperature exceeds a critical range. For example, the processor may maintain the output without changing it as long as the difference remains within the critical range; however, if the measured temperature fluctuates and the difference exceeds the critical range again, it can adjust the output by performing the proportional control described earlier once more. In this way, the processor can repeatedly determine whether the difference is within the critical range and continue the operation of maintaining or readjusting the output based on the result.

[0113] As an example of a scenario in which the processor maintains the output, if the subject's body temperature rises and the difference between the measured temperature and the target temperature falls within a threshold range of 0.5 degrees Celsius, the processor can maintain the output at that point to keep the body temperature stable near the target temperature. If the measured temperature subsequently drops and the difference exceeds 0.5 degrees Celsius again, the processor can increase the output to raise the body temperature back to the target temperature. By controlling the output to be maintained when the difference is within the threshold range in this way, excessive changes in the output due to minute fluctuations in the measured value are prevented, and the body temperature can be maintained stably near the target temperature.

[0114] According to one embodiment, a customized thermal detox method using closed-loop feedback control based on body temperature may further include: a processor acquiring a subject's biosignal from a biosensor; a processor calculating a subject's state value from the acquired biosignal; a processor comparing the calculated state value with a preset reference value; and a processor controlling the output of a thermal device to decrease or stop when the calculated state value exceeds the preset reference value.

[0115] The processor of the electronic device (100) can obtain the subject's biosignals from a biosensor. A biosignal is a signal obtained by measuring physiological phenomena occurring in the subject's body, and may refer to various types of signals that can be used to determine the subject's physical condition. For example, the biosignals may include a heart rate signal corresponding to the subject's heartbeat, a heart rate corresponding to the number of times the heart beats per unit time, a respiration signal corresponding to respiration, skin conductivity corresponding to the electrical properties of the skin, or blood oxygen saturation.

[0116] A biosensor is a device that measures biosignals generated from a subject's body and outputs them as electrical signals, and can be implemented in various forms depending on the type of biosignal to be measured. For example, a biosensor can be implemented as an electrode-type sensor that measures an electrocardiogram by contacting the subject's skin, a photoplethysmography sensor that measures pulse and oxygen saturation using light, or a sensor embedded in a wearable device worn by the subject. The biosensor can be connected to an electronic device (100) via a wired or wireless connection to transmit the measured biosignals to a processor.

[0117] As an example of a scenario in which a processor acquires biosignals, while a heating device is operating and the subject's body temperature is rising, the processor can continuously monitor the subject's physical condition by receiving biosignals corresponding to heart rate from a biosensor worn by the subject at regular intervals. The processor can utilize these acquired biosignals as basic data to determine the subject's safety status, separate from the measured temperature corresponding to body temperature. Through this operation of acquiring biosignals, the subject's physical response can be monitored in real time during the thermal management process.

[0118] The processor of the electronic device (100) can calculate a state value of the subject from the acquired biosignal. A state value is a value that quantitatively represents the physical condition of the subject and may refer to a value derived by processing or analyzing the acquired biosignal. The operation of calculating the state value may not use the measured biosignal as is, but may include a process of removing noise included in the biosignal or combining signals of a certain interval to convert it into a value that more stably represents the subject's condition.

[0119] The method by which the processor calculates the state value can be implemented in various ways depending on the type of biosignal. For example, if the biosignal is a heart rate signal, the processor can calculate the heart rate corresponding to the number of beats per unit time from the heart rate signal measured over a certain period and use this as the state value. As another example, the processor can calculate the average or trend of change of the biosignal measured over a certain interval and use it as the state value; furthermore, as yet another example, it can calculate a single comprehensive value representing the degree of physical burden on the subject as the state value by considering multiple types of biosignals together.

[0120] As an example of a scenario in which a processor calculates a state value, if a subject's heart rate changes as their body temperature rises due to thermal management, the processor can analyze the heart rate signal received from the biosensor at regular intervals to calculate a state value corresponding to the heart rate per minute. The processor can use this calculated state value as a criterion to determine whether the subject's physical burden is within an appropriate range. Through this operation of calculating a state value from biosignals, the subject's physical condition can be expressed as a comparable quantitative value.

[0121] The processor of the electronic device (100) can compare the calculated state value with a preset reference value. The reference value is a boundary value for determining whether the physical burden on the subject is excessive, and may be preset as a value of the same type as the state value and stored in the memory of the electronic device (100). For example, if the state value corresponds to a heart rate, the reference value may be set as a limit value of heart rate per minute at which it can be determined that an excessive burden has occurred on the subject.

[0122] The threshold value can be set in various ways. For example, the threshold value can be set as a fixed value that applies commonly to all subjects, or, as another example, it can be set differently depending on the subject's age, gender, or body type. As yet another example, the threshold value can be set as a value obtained by adding a certain margin to the reference state value calculated from the biosignals measured before the subject receives care. The processor can read the threshold value set in this way from memory or receive it from an external server (220) and use it for comparison.

[0123] As an example of a scenario where a processor compares a status value with a reference value, the processor may repeatedly compare a status value corresponding to heart rate per minute, calculated at regular intervals during thermal management, with a reference value corresponding to a preset heart rate limit for the subject. Through this comparison, the processor can determine whether the calculated status value has exceeded the reference value. In this way, through the operation of comparing the status value with the reference value, it can be determined whether the subject's physical burden has exceeded a predetermined limit.

[0124] The processor of the electronic device (100) can control the output of the heating device to be reduced or stopped if the calculated state value exceeds a preset threshold. If the processor determines that the state value resulting from the comparison performed earlier has exceeded the threshold, it may send a control signal to the heating device to reduce the output of the heating device or stop the heating of the heating device, considering that the subject's physical burden has reached an excessive state. Controlling the output to be reduced or stopped may mean lowering the power applied to the heating device or the temperature of the heating element, or stopping the heating of the heating device itself.

[0125] The method by which the processor reduces or stops the output can be implemented in various ways depending on the extent to which the state value exceeds a threshold. For example, if the state value slightly exceeds the threshold, the processor may reduce the output of the heating device to a certain extent to alleviate the burden on the subject while continuing management, and if the state value significantly exceeds the threshold, the processor may immediately stop the heating of the heating device to prioritize the safety of the subject. In addition, along with reducing or stopping the output, the processor may send a notification regarding the subject's state to the user terminal (210) so that the subject or manager can be aware of it.

[0126] As an example of a scenario in which the processor reduces or stops the output, if it is determined that a status value corresponding to the subject's heart rate per minute exceeds a preset threshold during thermal management, the processor can immediately lower the output of the heating device or stop the heating to prevent the heat burden applied to the subject's body from increasing further. By controlling the output to be reduced or stopped when the status value exceeds the threshold in this manner, it is possible to prevent excessive physical burden on the subject during the thermal management process and ensure the subject's safety.

[0127] According to one embodiment, the operation of acquiring detox information may include the operation of a processor acquiring a reference temperature of a subject measured before the thermal device operates from a temperature sensor, the operation of a processor acquiring body type information set for the subject, the operation of a processor identifying a correction value corresponding to the acquired body type information, and the operation of a processor determining a target temperature based on the acquired reference temperature and the identified correction value.

[0128] The processor of the electronic device (100) can obtain a reference temperature of the subject measured before the heating device operates from a temperature sensor. The reference temperature is a value corresponding to the subject's body temperature before heating by the heat is performed, and may represent the subject's normal body temperature or the body temperature at the time of starting treatment. The reference temperature is a value of the same type as the measured temperature corresponding to the body temperature, but can be distinguished from the measured temperature obtained during heating in that it is measured before the heating device starts heating.

[0129] The processor can acquire a reference temperature using a temperature sensor, similar to the method used to acquire the measured temperature. For example, the processor may acquire the reference temperature by receiving a value corresponding to the subject's body temperature from a temperature sensor while the subject is positioned in a space equipped with a heating device for treatment and the device has not yet started heating. The reference temperature may be acquired as a single value measured at a specific point in time, or it may be acquired as the average of values ​​measured repeatedly over a certain period to enhance measurement stability.

[0130] As an example of a scenario in which the processor acquires a reference temperature, immediately after a patient enters the treatment room and takes a seat on a heated bed, and before the heating device has started heating, the processor can acquire a reference temperature, such as 36 degrees Celsius, by receiving a value corresponding to the patient's body surface temperature from a temperature sensor. The processor can use this acquired reference temperature as basic data to determine a target temperature suitable for the patient. Through this operation of acquiring the reference temperature, the individual patient's physical condition before heating is identified, thereby establishing a starting point for the personalization of the target temperature.

[0131] The processor of the electronic device (100) can obtain body type information set for the subject. Body type information is information indicating the result of classifying the subject's physical characteristics into one of a plurality of predetermined types, and can indicate what physical tendencies the subject has. For example, the body type information may include the result of classifying whether the subject's normal body temperature tends to be low or high, or whether the body is in a state requiring relaxation or a state requiring vitality, and such classification may be made according to predetermined criteria.

[0132] The method by which the processor acquires body type information can be implemented in various ways. For example, the processor can acquire body type information by receiving via communication body type information entered by a subject or administrator through a user terminal (210), or, as another example, by receiving via communication body type information for each subject that is pre-stored in an external server (220). As yet another example, the processor can acquire body type information determined as a result of a diagnosis performed separately on the subject by reading it from the memory of the electronic device (100). Body type information can be acquired as information input from the outside or pre-stored, and the specific method by which the classification is performed is not limited to a specific one.

[0133] As an example of a scenario in which the processor acquires body type information, if a subject selects or inputs a classification result regarding their physical characteristics through a user terminal (210) prior to receiving care, the processor can receive the body type information and determine whether the subject belongs to a type with a tendency for low body temperature or to another type. The processor can use the body type information acquired in this way to determine the target temperature along with the reference temperature. Through the operation of acquiring body type information in this manner, the subject's physical tendency can be secured in a form that can be reflected in the determination of the target temperature.

[0134] The processor of the electronic device (100) can identify a correction value corresponding to the acquired body type information. A correction value is a value that is added or reflected to adjust the target temperature according to the subject's body type when determining the target temperature, and different values ​​may be predetermined corresponding to each body type. For example, the correction value may be set to a value that adjusts the target temperature relatively high for a body type with a tendency to have a low body temperature, and to a value that adjusts the target temperature relatively low for a body type with a tendency to have a high body temperature.

[0135] The method by which the processor identifies the correction value may be achieved by utilizing the correspondence relationship between the body type and the correction value. For example, the memory of the electronic device (100) may have correction values ​​corresponding to each of a plurality of body types stored in advance, and the processor may identify the correction value by reading from the memory the correction value corresponding to the type indicated by the acquired body type information. As another example, the processor may identify the correction value by body type stored in an external server (220) by receiving it via communication, in which case the correction value may be a value updated through the analysis of management results for a plurality of subjects.

[0136] As an example of a scenario in which the processor identifies a correction value, if the acquired body type information indicates a tendency toward low body temperature, the processor can read the correction value corresponding to that type from the body type-specific correction values ​​stored in memory and identify a correction value that adjusts the target temperature higher than usual. The processor can use this identified correction value along with the reference temperature to determine the target temperature. Through this operation of identifying a correction value corresponding to the body type information, the subject's physical tendency can be converted into a value that can be quantitatively reflected in the target temperature.

[0137] The processor of the electronic device (100) can determine a target temperature based on the acquired reference temperature and the identified correction value. Determining the target temperature may mean determining a body temperature that serves as a target suitable for the subject by considering together the reference temperature corresponding to the subject's physical condition before heating and the correction value corresponding to the subject's physical tendency. The target temperature determined in this way can serve as a standard for subsequent output control and temperature maintenance.

[0138] The method by which the processor determines the target temperature can be implemented in various ways. For example, the processor may determine the target temperature by adding a correction value to the reference temperature; in this case, a higher target temperature may be determined from the reference temperature for body types with larger correction values. As another example, the processor may calculate the target temperature by considering the difference between the reference temperature and a predetermined reference body temperature, so that the target temperature is determined relatively higher for subjects with lower reference temperatures. The specific relationship for calculating the target temperature from the reference temperature and the correction value may also be implemented in the form of a separately described mathematical formula.

[0139] As an example of a scenario in which a processor determines a target temperature, if a subject's reference temperature is 36 degrees Celsius and a correction value is identified to raise the target temperature because the subject belongs to a body type with a tendency for low body temperature, the processor can determine a target temperature such as 38.5 degrees Celsius by applying the corresponding correction value to the reference temperature. On the other hand, even if the reference temperature is the same, a different target temperature may be determined for subjects belonging to different body types by applying the corresponding correction value. Through this operation of determining the target temperature based on the reference temperature and correction value, management goals can be personalized to match the individual physical condition and tendencies of each subject.

[0140] According to one embodiment, a customized thermal detox method using closed-loop feedback control based on body temperature may further include: a processor controlling the operation of a ventilation device provided in a space where a subject is located after controlling the output of a thermal device to decrease; a processor acquiring a measured temperature corresponding to the subject's body temperature from a temperature sensor; and a processor controlling the operation of the ventilation device to stop when the acquired measured temperature reaches a preset termination temperature.

[0141] The processor of the electronic device (100) can control the operation of a ventilation device provided in the space where the subject is located after controlling the output of the heating device to decrease. A ventilation device is a device that lowers the temperature of the space or ventilates the air by circulating the air in the space where the subject is located or exchanging it with outside air, and can be implemented as a device of various forms that generates airflow or discharges and draws in air. For example, the ventilation device can be implemented as a blower fan, an exhaust device provided in a ventilation opening, or an air conditioning device having both cooling and ventilation functions, and the form of implementation is not limited to a specific one.

[0142] The point at which the processor operates the ventilation device can be determined after the operation to control the output of the heating device to decrease. That is, after the maintenance time has elapsed and the output of the heating device has decreased or the heating has stopped, the processor can transmit a control signal instructing the ventilation device to start operation, thereby causing the ventilation device to start circulating the air in the space or exhausting it to the outside. The ventilation device can be connected to the electronic device (100) via a wired or wireless connection to receive the control signal transmitted by the processor, and can start operation according to the received control signal.

[0143] As an example of a scenario in which the processor operates a ventilation device, after the target temperature is reached and maintained, the maintenance time has elapsed, and the output of the heating device has decreased to complete the heating process, the processor may operate the ventilation device to circulate the air in the space heated by the heating and begin to lower the temperature of the space where the subject is located. By controlling the ventilation device to operate after the operation to control the output to decrease in this manner, a finishing process may be initiated so that the subject, after the heating has ended, does not remain in the heated space but can complete the care in a comfortable environment.

[0144] The processor of the electronic device (100) can obtain a measured temperature corresponding to the subject's body temperature from the temperature sensor. The measured temperature obtained here is a newly measured value to determine how the subject's body temperature changes while the ventilation device is operating and the space is being ventilated; it is a value of the same type as the measured temperature obtained in the previous heating section, but can be distinguished in that it is obtained during the final stage of management. The processor can receive the measured temperature from the temperature sensor at regular intervals while the ventilation device is operating to determine the pattern of the subject's body temperature gradually decreasing.

[0145] The processor can reacquire the measured temperature using a temperature sensor, similar to the method used to acquire the temperature during the heating phase. As the temperature of the space decreases due to the operation of the ventilation system, the subject's body temperature may also gradually decrease, and the processor can continuously monitor this process of body temperature decline through the measured temperature. The frequency for reacquiring the measured temperature may be set to be the same as the frequency during the heating phase, or it may be set differently to suit the characteristics of the finishing process.

[0146] As an example of a scenario where the processor reacquires the measured temperature, while the ventilation system is operating and air is circulating in the space, the processor receives the measured temperature corresponding to the subject's body temperature from the temperature sensor at regular intervals to determine how much the subject's body temperature has dropped compared to the time when heating ended. The processor can use this reacquired temperature as a criterion to decide when to stop the operation of the ventilation system. Through this operation of reacquiring the measured temperature, the subject's body temperature can be monitored in real time even during the final stages of management.

[0147] The processor of the electronic device (100) can control the operation of the ventilation device to stop when the reacquired measured temperature reaches a preset end temperature. The end temperature is a reference value corresponding to the body temperature of the subject at which the final management process can be considered to be terminated, and may be preset and stored in the memory of the electronic device (100) to determine whether the subject's body temperature has dropped to a sufficiently stable level. For example, the end temperature may be set to a value close to the subject's normal body temperature or to a value corresponding to the reference temperature measured before heating.

[0148] The method by which the processor stops the operation of the ventilation device can be implemented by comparing the newly acquired measured temperature with the termination temperature. For example, the processor can repeatedly compare the newly acquired measured temperature with the termination temperature while the ventilation device is operating, and if it is determined that the measured temperature has reached the termination temperature or dropped below the termination temperature, it can transmit a control signal instructing the ventilation device to stop operation. Whether the measured temperature has reached the termination temperature can be determined based on whether the measured temperature becomes equal to the termination temperature or falls within a certain range including the termination temperature.

[0149] As an example of a scenario in which the processor stops the operation of the ventilation device, when the ventilation device operates and the subject's body temperature gradually decreases until the newly acquired measured temperature reaches the end temperature of 36.5 degrees Celsius, the processor may consider the subject's body temperature to be sufficiently stable and stop the operation of the ventilation device to terminate the final management process. By controlling the operation so that the ventilation device stops when the newly acquired measured temperature reaches the end temperature in this manner, management can be completed at the point when the subject's body temperature returns to a stable level, and unnecessary ventilation can be prevented from continuing.

[0150] Meanwhile, the processor of the electronic device (100) can calculate the output of the heating device based on the following mathematical formula 1 when the difference between the measured temperature and the target temperature exceeds a preset threshold range. Mathematical formula 1 can be expressed in the form of proportional control so that the output of the heating device is determined in proportion to the degree to which the measured temperature is separated from the target temperature.

[0151] <Mathematical Formula 1>

[0152]

[0153] Here is the point in time It refers to the output applied to the heating device, refers to the preset default output, and represents a preset proportionality coefficient, and represents the target temperature, and is the point in time It can refer to the measured temperature obtained from the temperature sensor.

[0154] The specific meaning of each parameter is explained as follows. Output The heating device at the point As a value corresponding to the magnitude of heat generated, it can be expressed as the magnitude of power applied to the heating device or the target temperature of the heating element. Basic output is a reference output applied to the heating device when the measured temperature and the target temperature match, and can correspond to the minimum degree of heating required to maintain body temperature near the target temperature. Proportionality coefficient is a value that determines the extent to which the difference between the measured temperature and the target temperature is reflected in the output, and the larger this value is, the more the output can change for the same difference.

[0155] The method by which the electronic device (100) acquires each parameter may vary depending on the nature of the parameter. Target temperature is a value determined during the process of acquiring detox information mentioned earlier, and the processor can read the target temperature from the detox information and use it in Equation 1. Measured temperature The processor from the temperature sensor at As a value obtained each time, it is substituted into Equation 1 whenever the measured temperature is updated to calculate the output at that point in time. Basic output and proportionality constant These are values ​​that are pre-set and stored in the memory of the electronic device (100), and the processor can read these values ​​from the memory and use them whenever it produces an output, and as another example, it can receive and use updated values ​​from an external server (220).

[0156] Basic output and proportionality constant The values ​​can be determined in various ways. For example, the basic output and proportionality coefficient may be set to fixed values ​​that are predetermined by considering the heating characteristics of the heating device or the environment of the management space, or, as another example, may be set to different values ​​depending on the subject's body type or the type of management program. As yet another example, the basic output and proportionality coefficient may be values ​​updated through the analysis of accumulated management results for multiple subjects, in which case an external server (220) may provide the updated values ​​to the electronic device (100) by analyzing the accumulated management history.

[0157] An example of a scenario in which Mathematical Equation 1 is applied is as follows. If the measured temperature is significantly lower than the target temperature at the beginning of treatment, the difference between the target temperature and the measured temperature corresponding to the value inside the parentheses is calculated to be large. Consequently, the value added to the base output after multiplying by the proportionality constant increases, allowing the output of the heating device to be set relatively high. As a result, the subject's body temperature rises rapidly. As the body temperature rises and the measured temperature approaches the target temperature, the value inside the parentheses gradually decreases, allowing the output to be lowered to a level close to the base output. In this way, by continuously adjusting the output in proportion to the difference, the body temperature can smoothly converge toward the target temperature.

[0158] The technical significance of Equation 1 lies in the fact that it continuously and quantitatively determines the control quantity, which is the output of a heating device, based on a single input, namely the difference between the measured temperature and the target temperature. Compared to a method that turns the output on and off simply by determining whether the measured temperature has reached the target temperature, proportional control according to Equation 1 finely adjusts the output in response to the magnitude of the difference; thus, it can mitigate excessive temperature rise or sudden fluctuations in output that may occur during the process of the body temperature reaching the target temperature. In other words, closed-loop control that feeds back the measured value as the control quantity can be implemented in a quantitative form.

[0159] The differential effects obtained through Mathematical Equation 1 can be summarized as follows. First, since the output is determined proportionally to the difference, the body temperature is raised rapidly when it is far from the target temperature and approached gradually when it is close, thereby shortening the time to reach the target temperature while suppressing excessive heating that significantly exceeds the target temperature. Second, since the base output and proportionality coefficient can be set differently depending on the subject or management program, output control characteristics suitable for each subject can be implemented while maintaining the same control structure. Third, since the proportionality coefficient and base output can be updated through the analysis of management history, the precision of output control can be gradually improved as management accumulates.

[0160] Meanwhile, the processor of the electronic device (100) can calculate the output of the heating device by reflecting not only the difference between the measured temperature and the target temperature but also the degree to which the difference changes over time when the difference between the measured temperature and the target temperature exceeds a preset threshold range. This relationship can be expressed in a form that includes a term proportional to the rate of change of the difference over time in addition to a term proportional to the difference, as shown in the following mathematical formula 2.

[0161] <Mathematical Formula 2>

[0162]

[0163] Here is the point in time It refers to the output applied to the heating device, refers to the preset default output, and represents a preset proportionality coefficient, and represents a preset derivative, and means the target temperature, and is the point in time It can refer to the measured temperature obtained from the temperature sensor.

[0164] Basic output in Math Equation 2 , proportionality coefficient , target temperature , measured temperature The meaning of can be the same as in the case where proportional control was explained earlier. The newly added term is the derivative of the difference between the target temperature and the measured temperature with respect to time, multiplied by the derivative coefficient; it serves to reflect in the output how quickly the difference changes over time. Derivative coefficient is a value that determines the extent to which the rate of change of this difference is reflected in the output, and the larger this value, the greater the effect the rate of change of the difference can have on the output.

[0165] The specific meaning of the term corresponding to the rate of change of the difference over time is as follows. In the section where the measured temperature rises rapidly toward the target temperature, the difference between the target temperature and the measured temperature decreases rapidly; in this case, the derivative of the difference with respect to time corresponds to the direction in which the difference decreases. This term, multiplied by the derivative coefficient, acts to lower the output, allowing the output to be mitigated in advance when the body temperature rapidly approaches the target temperature. Conversely, in the section where the difference hardly changes, this term has almost no effect on the output, so the output can be set close to the value determined by proportional control.

[0166] The method by which the electronic device (100) obtains the rate of change of the difference can be achieved by using the measured temperature obtained over time. The processor obtains the measured temperature from the temperature sensor at regular intervals and can calculate a value corresponding to the rate of change of the difference over time by dividing the amount of change of the difference calculated from the measured temperatures obtained at two consecutive points in time by the time interval between them. For example, the processor can approximate and calculate a value corresponding to a continuous derivative in a discrete form by dividing the difference between the difference calculated at the previous point in time and the difference calculated at the current point in time by the time interval between the two points in time. Derivative coefficient The basic output or proportionality coefficient may be pre-set and stored in the memory of the electronic device (100), and the processor may read it from memory or receive and use an updated value from an external server (220) whenever it produces an output.

[0167] An example of a scenario to which Equation 2 applies is as follows. In the initial stages of treatment, when the measured temperature is significantly lower than the target temperature and the heating device heats at a high output, causing the body temperature to rise rapidly, the term based on proportional control still indicates a high output. However, as the difference is rapidly decreasing, the term based on differential control acts to lower the output, thereby mitigating the phenomenon where the output is maintained excessively and exceeds the target temperature once the body temperature reaches the target temperature. On the other hand, if the body temperature rises slowly and the difference decreases gradually, the influence of the term based on differential control becomes smaller, allowing the output to be maintained close to the value based on proportional control.

[0168] The technical significance of Equation 2 lies in the fact that it reflects not only the current state—the difference between the measured temperature and the target temperature—but also the trend of that difference in the output. When only proportional control is applied, a high output is maintained in the range where the difference is large, which can lead to an excessive rise in temperature that exceeds the target temperature due to inertia when the body temperature reaches the target temperature. However, by adding a term that reflects the rate of change of the difference, such excessive temperature rise can be suppressed in advance. In other words, control corresponding to the current difference and control corresponding to the trend of the difference's change are performed together, allowing the body temperature to converge to the target temperature more stably.

[0169] The differential effects obtained through Equation 2 can be summarized as follows. First, by reflecting the rate of change of the difference, excessive temperature rise that may occur when the body temperature reaches the target temperature can be suppressed, thereby reducing fluctuations in body temperature around the target temperature. Second, since the output is pre-adjusted according to the speed at which the body temperature approaches the target temperature, the time required for the measured temperature to stabilize near the target temperature after reaching it can be shortened compared to the case where only proportional control is applied. Third, by adjusting the proportional and derivative coefficients respectively, the balance between the speed of temperature rise and stability can be finely controlled to suit the characteristics of the subject or management program.

[0170] Meanwhile, the processor of the electronic device (100) can calculate the target temperature according to the following mathematical formula 3 based on the reference temperature of the subject measured before the heating device operates and the correction value corresponding to the subject's body type information. Mathematical formula 3 can be expressed in a form that sets the target temperature by taking the reference temperature corresponding to the subject's body condition before heating as a starting point, and reflecting together the correction according to the body type and the correction according to the degree to which the reference temperature deviates from the normal reference body temperature.

[0171] <Mathematical Formula 3>

[0172]

[0173] Here It refers to the determined target temperature, and refers to the reference temperature measured before the heating device operates, represents a correction value identified in correspondence with body type information, and means a preset reference body temperature, may refer to a preset coefficient that determines the degree to which the difference between the reference temperature and the reference body temperature is reflected in the target temperature.

[0174] The specific meaning of each parameter is explained as follows: Target temperature is the target body temperature suitable for the subject, and the value calculated by Equation 3 can serve as the standard for subsequent output control and temperature maintenance. Reference temperature is the subject's body temperature measured before the heating device begins heating, and can serve as a starting point indicating the subject's physical condition prior to heating. Correction value corresponding to the body type It is a value added to raise or lower the target temperature according to the subject's physical tendencies, and different values ​​may be pre-determined for each body type. Reference body temperature is a reference value for normal body temperature that can be generally applied to a large number of subjects, and it can serve as a measure to determine how much the temperature deviates from this reference value. Coefficient may be a value that determines the extent to which the reference temperature deviates from the reference body temperature and is reflected in the target temperature.

[0175] The method by which the electronic device (100) acquires each parameter may vary depending on the nature of the parameter. Reference temperature is a value obtained by the processor from the temperature sensor before the operation of the heating device, and the measured reference temperature can be directly substituted into Equation 3. Correction value corresponding to the body type is a value obtained by the processor identifying a value corresponding to the acquired body type information, and can be obtained by reading a value corresponding to the corresponding body type among the correction values ​​stored for each body type in the memory of the electronic device (100). Reference body temperature and coefficients These are values ​​that are pre-set and stored in the memory of the electronic device (100). When calculating the target temperature, the processor can read these values ​​from the memory and use them, or, as another example, receive and use updated values ​​from an external server (220).

[0176] Correction values ​​and coefficients corresponding to body types can be determined in various ways. For example, the correction value may be set to a value that raises the target temperature for body types with a tendency to have a low body temperature, and to a value that lowers the target temperature for body types with a tendency to have a high body temperature. The coefficient may be set to act in a direction that further raises the target temperature for subjects whose reference temperature is lower than the reference body temperature, and the correction values ​​and coefficients may be updated through the analysis of accumulated management results for multiple subjects. In this case, an external server (220) may analyze the accumulated management history and provide the updated values ​​to the electronic device (100).

[0177] An example of a scenario in which Equation 3 is applied is as follows. If a subject's reference temperature is measured to be lower than the reference body temperature and the subject belongs to a body type prone to low body temperature, a correction value corresponding to the body type is added in a direction that raises the target temperature. Additionally, a term in which the difference between the reference temperature and the reference body temperature is multiplied by a coefficient also acts in a direction that raises the target temperature, resulting in a target temperature higher than usual. On the other hand, for a subject whose reference temperature is close to the reference body temperature and for whom the correction based on body type is not significant, a target temperature close to the reference temperature may be calculated. In this way, different target temperatures can be determined for each subject within the same control structure.

[0178] The technical significance of Equation 3 lies in the fact that the target temperature is not applied uniformly to all subjects, but is calculated individually for each subject by quantitatively reflecting two factors: the subject's physical condition before heating and physical tendencies. By using the reference temperature as the starting point, the physical condition before heating is reflected; by adding a correction value corresponding to the body type, the subject's physical tendencies are reflected; and by adding a term obtained by multiplying the difference between the reference temperature and the reference body temperature by a coefficient, the degree of deviation from the normal body temperature level can be reflected. Consequently, the target temperature can be determined not as a single value, but as a value that varies according to the subject's condition.

[0179] The differential effects obtained through Equation 3 can be summarized as follows. First, since the reference temperature is used as the starting point, different target temperatures are calculated for subjects with low and high body temperatures prior to heating, allowing for an appropriate level of temperature increase for each subject. Second, by adding a correction value corresponding to body type as a separate term, the target temperature can be differentiated according to physical tendencies even among subjects with the same reference temperature. Third, through a term reflecting the difference between the reference temperature and the reference body temperature, the target temperature can be further adjusted for subjects with low normal body temperatures, thereby providing a management goal that is more suitable and manageable for the subject compared to applying a uniform target temperature.

[0180] Additionally or generally, according to one embodiment, a processor of an electronic device (100) can control a sound output device provided in a space where a subject is located to output a preset first sound. A sound output device is a device that converts an electrical signal into sound and outputs it to a space, and can be implemented as various types of devices such as a speaker, a soundbar, or a sound module embedded in a ceiling or wall. The first sound is a sound provided to the subject during the initial phase of care, and may be preset as music or nature sounds to relieve the subject's tension and stored in the memory of the electronic device (100). By transmitting a control signal to the sound output device to cause the first sound to be output to the space, the processor can enable the subject to feel auditory stability from the moment care begins.

[0181] The processor of the electronic device (100) can calculate the difference between the measured temperature and the target temperature. The difference is a value indicating the degree to which the measured temperature, corresponding to the subject's body temperature, deviates from the target temperature. Whenever the processor obtains the measured temperature from the temperature sensor, it calculates the difference between the measured temperature and the target temperature to continuously update how close the body temperature is to the target temperature. The processor can use the difference calculated in this way as a standard for adjusting the output speed of the sound.

[0182] The processor of the electronic device (100) can control the sound output device so that the output speed of the first sound becomes slower as the calculated difference becomes smaller. Output speed refers to the speed at which the first sound is played, and may mean the tempo of the music corresponding to the number of beats repeated per unit time. As the body temperature rises and the difference between the measured temperature and the target temperature gradually decreases, the processor can gradually adjust the output speed of the first sound to slow down so that the tempo of the music gradually slows down. For example, when the difference is large at the beginning of management, the first sound is played at a relatively fast tempo, but as the body temperature rises and the difference becomes smaller, the tempo gradually slows down, allowing the subject to auditorily experience the flow of deepening physical relaxation. The method of adjusting the output speed can be implemented by gradually lowering the playback speed of the first sound or by selecting a sound source corresponding to the magnitude of the difference from among a plurality of sound sources prepared in advance with different tempos.

[0183] The processor of the electronic device (100) can control the sound output device to output a second sound different from the first sound when the measured temperature reaches the target temperature. The processor determines whether the measured temperature obtained from the temperature sensor has reached the target temperature, and if it is determined that the measured temperature has reached the target temperature, it can transmit a control signal to the sound output device to switch the output sound from the first sound to the second sound. The second sound is a separate sound distinct from the first sound, and may be a sound with fewer beats per unit time than the first sound. That is, the second sound is a sound with a slower tempo than the first sound, and may be pre-set as a sound that induces deeper relaxation by allowing the subject to auditorily perceive that the body temperature has reached the target temperature and entered the core phase of management. For example, before the measured temperature reaches the target temperature, the first sound corresponding to calm music may be output, and when the measured temperature reaches the target temperature, it may be switched to the second sound corresponding to a sound with a slower beat.

[0184] The processor of the electronic device (100) can control the volume of the sound output device so that it is maintained below a preset reference volume while the second sound is being output. The reference volume is a sound level that does not disturb the subject's stability during the core section of the management, and may be preset and stored in the memory of the electronic device (100). The processor controls the volume of the sound output device so that it does not exceed the reference volume while the second sound is being output, thereby allowing the subject to remain calm without being exposed to excessive sound during the core section where the body temperature is maintained at the target temperature. For example, even if no separate upper limit is set for the volume during the section where the first sound is being output, the volume may be limited below the reference volume after switching to the second sound so that the sound remains calm. In this way, the speed of sound output, the switching of the sound, and the volume after the switching are controlled in conjunction with changes in the measured temperature, so that the subject can naturally perceive the progress stage of the management and the degree of physical relaxation through sound.

[0185] Additionally or generally, according to one embodiment, the processor of the electronic device (100) can control a lighting device provided in a space where a subject is located to output light of a preset first color temperature. A lighting device is a device that provides light to a space and can be implemented as various types of light-emitting devices, such as light-emitting diode lighting, capable of adjusting the color temperature of the output light. Color temperature is a value representing the color characteristics of light, and the higher the color temperature, the more it corresponds to a cool, bluish light, and the lower the color temperature, the more it corresponds to a warm, reddish light. The first color temperature is the color temperature of the light output at the beginning of management and may be preset and stored in the memory of the electronic device (100), and the processor can transmit a control signal to the lighting device to cause light of the first color temperature to be output.

[0186] The processor of the electronic device (100) can calculate the difference between the measured temperature and the target temperature. Whenever the processor obtains the measured temperature from the temperature sensor, it calculates the difference between the measured temperature and the target temperature to continuously determine how close the body temperature is to the target temperature. The processor can use the difference calculated in this way as a standard for determining the color temperature of the light output by the lighting device.

[0187] The processor of the electronic device (100) can control the lighting device to output light of a first color temperature if the calculated difference is greater than or equal to a preset first reference value. The first reference value is a value that serves as a boundary for determining whether the body temperature is sufficiently far from the target temperature, and may be preset and stored in the memory of the electronic device (100). If the processor determines that the calculated difference is greater than or equal to the first reference value, it may control the lighting device to output light of a relatively high first color temperature, considering the body temperature as being in an initial management period far from the target temperature. For example, when management has just started and the measured temperature is significantly lower than the target temperature, the difference is greater than or equal to the first reference value, and light of a first color temperature that gives a calm yet clear impression may be output.

[0188] The processor of the electronic device (100) can control the lighting device to output light of a second color temperature lower than the first color temperature when the calculated difference is greater than or equal to a second reference value that is smaller than the first reference value and less than the first reference value. The second reference value is a value smaller than the first reference value and may be another boundary value for determining how close the body temperature is to the target temperature. If the processor determines that the calculated difference is between the first reference value and the second reference value, it can control the lighting device to output light of a second color temperature lower than the first color temperature, considering it as an intermediate section where the body temperature is rising toward the target temperature. Accordingly, as the body temperature rises, the light in the space changes to a warmer feeling than before, allowing the subject to visually perceive that care is being provided.

[0189] The processor of the electronic device (100) may output light of a third color temperature lower than the second color temperature at a preset periodic interval when the calculated difference is less than the second reference value. The third color temperature is a color temperature lower than the second color temperature and may be the color temperature of light corresponding to the warmest feeling. When the processor determines that the calculated difference is less than the second reference value, it may control the lighting device to output light of the third color temperature at a preset periodic interval, considering the body temperature as being sufficiently close to the target temperature, and control the brightness of the light to gradually increase and decrease at a preset periodic interval. For example, in the interval where the body temperature has almost reached the target temperature, the warmest light of the third color temperature may fluctuate in brightness at a constant periodic interval, forming a rhythm similar to breathing, thereby visually inducing the subject to reach the deepest state of relaxation. In this way, by dividing the difference between the measured temperature and the target temperature into multiple intervals and differentially controlling the color temperature and brightness fluctuations, the visual atmosphere of the space can be created to harmonize with the changes in the body condition according to the progress stage of management.

[0190] Additionally or generally, according to one embodiment, the processor of the electronic device (100) may control the first sprayer to spray a first fragrance when the measured temperature reaches the target temperature, provided that the first sprayer and the second sprayer are provided with a fragrance generator in the space where the subject is located and spray different fragrances. The fragrance generator is a device that sprays or diffuses a pre-prepared fragrance substance into a space and may be implemented by including a first sprayer and a second sprayer that each contain and spray different fragrance substances. The first fragrance is a fragrance sprayed by the first sprayer and may be pre-set as a fragrance suitable for being provided to the subject immediately after entering the core section of care. The processor may determine whether the measured temperature obtained from the temperature sensor has reached the target temperature, and if it is determined that the measured temperature has reached the target temperature, transmit a control signal to the first sprayer to spray the first fragrance into the space. For example, a fresh-feeling first fragrance may begin to be sprayed at the time when the body temperature reaches the target temperature, so that the subject can olfactorily perceive that they have entered the core section of care.

[0191] The processor of the electronic device (100) can control the first spray unit to stop spraying the first fragrance and the second spray unit to spray the second fragrance when a preset time has elapsed since the point at which the measured temperature reaches the target temperature. The preset time is a value that determines the length of the section in which the first fragrance is sprayed, and may be preset as a value shorter than the maintenance time and stored in the memory of the electronic device (100). The second fragrance is a fragrance sprayed by the second spray unit and may be a separate fragrance distinct from the first fragrance. The processor determines whether the time elapsed since the point at which the measured temperature reaches the target temperature has reached the preset time, and if it is determined that the preset time has elapsed, it transmits a control signal to stop spraying to the first spray unit while transmitting a control signal to start spraying to the second spray unit, thereby causing the fragrance provided to the space to switch from the first fragrance to the second fragrance. For example, a fresh first scent is provided at the beginning of the core phase of the treatment, and then switches to a deeper, more soothing second scent after a preset time has passed, allowing the subject to olfactorily experience the flow of the core phase of the treatment maturing.

[0192] The processor of the electronic device (100) can control the second spray unit to stop spraying the second fragrance when the maintenance time has elapsed. The processor determines whether the time measured from the point when the measured temperature reaches the target temperature has reached the maintenance time included in the detox information, and if it is determined that the maintenance time has elapsed, it can transmit a control signal to the second spray unit to stop spraying the second fragrance. Since the preset time is shorter than the maintenance time, both the period in which the first fragrance is provided and the period in which the second fragrance is provided are included within the core period of management, and the second fragrance can be provided from the point when the preset time has elapsed until the maintenance time has elapsed. For example, the first fragrance can be provided from the point when the body temperature reaches the target temperature, and after the preset time has elapsed, it switches to the second fragrance and is provided until the maintenance time ends, and when the maintenance time has elapsed, the spraying of the second fragrance can be stopped so that the fragrance created up to that point remains in the space. In this way, as different fragrances are sequentially sprayed and stopped according to temporal criteria such as the time when the target temperature is reached, a preset time, and a maintenance time, the type of fragrance is gradually switched in accordance with the progress of thermal management, thereby providing the subject with a changing olfactory experience.
