Description

Technical Field

[0001] This invention relates to the medical field, and more particularly to a therapeutic device and its control method. Background Technology

[0002] Therapeutic devices convert electrical energy into heat energy and radiate it onto the human body to relieve muscle pain, promote wound healing, or improve joint pain. Existing therapeutic devices typically use a fixed-power output scheme. However, the device itself is affected by fluctuations in the mains voltage, and the infrared radiation lamps within the device age over time, causing their radiation characteristics to gradually change. Furthermore, the energy radiated from the device to the body is also affected by ambient temperature. Therefore, a fixed-power output scheme cannot guarantee stable energy radiated to the body surface, nor can it ensure effective absorption of infrared radiation energy by the body, easily leading to thermal damage to the irradiated areas or poor therapeutic effects. Summary of the Invention

[0003] The purpose of this invention is to provide a therapeutic device and a control method for the therapeutic device, which features stable radiation temperature.

[0018] Optionally, when the second temperature sensor detects that the difference between the temperature of the radiated object and the target temperature value is greater than a preset value, the processing unit is further configured to deliver power to the radiator body at the maximum power that the battery can output in the current state, based on the remaining power of the battery and the operating status parameters.

[0019] Optionally, the battery's operating status parameters include at least one of the battery temperature, output voltage, and output current.

[0020] The present invention also provides a control method for a therapeutic device, comprising:

[0021] The treatment device described above is provided; the processing unit controls the power module to supply power to the radiator body through the power unit, and preheats the radiator body.

[0022] The first temperature sensor is used to monitor the temperature of the radiator body before and after preheating and calculate the temperature rise value. When the temperature rise value is within the normal range, the processing unit obtains the characteristic parameters of the radiator body based on the temperature rise value.

[0023] The temperature of the radiated object is monitored using a second temperature sensor. When the difference between the temperature of the radiated object and the target temperature value detected by the second temperature sensor is less than a preset value, the processing unit controls the amount of power output to the radiator body based on the difference and the characteristic parameters of the radiator body.

[0024] Optionally, the power supply module is an external mains power supply; when the second temperature sensor detects that the difference between the temperature of the radiated object and the target temperature value is greater than a preset value, the processing unit controls the power unit to output power to the radiator body at maximum power according to the difference and the characteristic parameters.

[0025] Optionally, the power module is a battery.

This ensures that the surface temperature of the radiated object remains stable, improving the temperature stability of the object heated by the therapeutic device. Attached Figure Description

[0045] The following will be combined with the appendix in the embodiments of the present invention. Figure 1 ~Attached Figure 3 The technical solutions, structural features, objectives and effects achieved in the embodiments of the present invention will be described in detail.

[0046] It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions. They are only used to facilitate and clarify the purpose of illustrating the embodiments of the present invention, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationship, or adjustments to the size should still fall within the scope of the technical content disclosed in the present invention, provided that they do not affect the effects and objectives that the present invention can produce.

[0047] It should be noted that, in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0048] like Figure 1 As shown, the present invention provides a therapeutic device 1. The therapeutic device 1 includes a radiator body 10, a power module 20, a first temperature sensor 30, a second temperature sensor 40, a power unit 51, and a processing unit 52.

[0049] The radiator body 10 receives electrical energy from the power module 20 and converts it into heat energy to heat the radiated object 60. When current passes through the heating element (such as a resistance wire) in the radiator body 10, electrical energy is converted into heat energy by the heating wire, causing the heating element to heat up and radiate infrared electromagnetic waves. When the infrared electromagnetic waves reach the surface of the radiated object 60, they raise the surface temperature of the object, thus heating its surface. The power module 20 supplies power to the radiator body 10 to ensure a stable power supply. Figure 1 The arrows in the diagram indicate the direction of the current or the direction of infrared radiation transmission.

[0050] The first temperature sensor 30 is used to monitor the temperature of the radiator body 10. When the radiator body 10 radiates energy outwards, its heat output and temperature are affected by various factors, such as changes in the input voltage of the power module 20, the aging of the radiator body 10 itself, and changes in the ambient temperature of the radiator body 10, resulting in significant variations in the radiated power output. However, the radiated power output of the radiator body 10 is related to its own temperature. By setting the first temperature sensor 30 to detect the temperature of the radiator body 10, the intensity of the radiated energy output by the radiator body 10 can be better monitored.

[0051] When the radiator body 10 radiates energy to the radiated object 60, the energy transfer process is affected by the environment between them. For example, when the ambient temperature is too low, more energy is lost during the transfer process. Therefore, even when the temperature of the radiator body 10 is the same, changes in the environment between the radiator body 10 and the radiated object 60 will result in different amounts of energy received by the radiated object 60, and consequently, different surface temperatures. To improve the control effect of the surface temperature of the radiated object 60, a second temperature sensor 40 is provided to monitor the temperature of the radiated object 60. By directly monitoring the surface temperature of the radiated object 60 through the second temperature sensor 40, the heating power of the radiator body 10 is adjusted according to the temperature detected by the second temperature sensor 40, achieving closed-loop control of the radiator body 10 and improving control accuracy.

[0052] The power unit 51 is electrically connected to the power module 20 and the radiator body 10. The power unit 51 is used to transfer electrical energy from the power module 20 to the radiator body 10, so that the radiator body 10 heats up and thus heats the radiated object 60.

[0053] The processing unit 52 is electrically connected to the first temperature sensor 30, the second temperature sensor 40, and the power unit 51. The processing unit 52 calculates the characteristic parameters of the radiator body 10 based on the temperature rise value measured by the first temperature sensor 30, which is within the normal range. Specifically, after the therapeutic device 1 is powered on, the radiator body 10 is preheated. Under a set time and voltage, the radiator body 10 is preheated. The first temperature sensor 30 continuously monitors the temperature of the radiator body 10, measuring the temperature before and after preheating, and then subtracting the temperatures to obtain the temperature rise value of the radiator body 10 before and after preheating. During the preheating process, the voltage and time for heating the radiator body 10 are fixed, and the heating characteristics of the radiator body 10 itself are also fixed. Therefore, the temperature rise value of the radiator body 10 can be calculated based on the radiator body 10 and the applied voltage time.

[0054] If the temperature rise of the radiator body 10 after preheating is within the normal range as measured by the first temperature sensor 30, the processing unit 52 calculates the characteristic parameters of the radiator body 10 based on this temperature rise. If the temperature rise of the radiator body 10 after preheating is outside the normal range as measured by the first temperature sensor 30, it indicates that the radiator body 10 is abnormal. In this case, the treatment device 1 needs to be turned off and a warning should be issued, indicating that the radiator body 10 cannot be used at this time.

[0055] When the second temperature sensor 40 detects that the difference between the temperature of the irradiated object 40 and the target temperature is less than a preset value, the processing unit 52 controls the power output of the power unit to the radiator body according to the difference and characteristic parameters.

[0056] In one embodiment, the therapeutic device 1 further includes a storage module 80, which is electrically connected to the processing unit 52. The storage module 80 is used to store characteristic parameters. When the second temperature sensor 40 detects that the difference between the temperature of the irradiated object 60 and the target temperature value is less than a preset value, the processing unit 52 reads the characteristic parameters from the storage module 80 and controls the power output of the power unit to the radiator body based on the characteristic parameters and the difference between the detected temperature value of the irradiated object 60 and the target temperature value.

[0057] In another embodiment, the processing unit 52 further includes a storage module 80, which is located inside the processing unit 52. The storage module 80 stores characteristic parameters. When the second temperature sensor detects that the difference between the detected value of the radiated object and the target temperature value is less than a preset value, meaning the surface temperature of the radiated object 60 is close to the target temperature, if the radiator body 10 continues to heat the radiated object 60 at its maximum achievable power, the surface temperature of the radiated object 60 could easily rise rapidly and exceed the target temperature. At this time, the processing unit 52 reads the characteristic parameters and, based on the characteristic parameters and the difference between the detected value of the radiated object 60 and the target temperature value, controls the power output of the power unit 52 to the radiator body 10. During this process, the processing unit 52 uses a temperature control algorithm to finely adjust the heating power of the radiator body 10 based on the temperature deviation, continuously making fine adjustments. This ensures that the surface temperature of the radiated object 60 gradually approaches the target temperature, avoiding overshoot and improving the user experience.

[0058] Specifically, when the processing unit 52 compares the temperature of the surface of the radiated object 60 with the set target temperature, if the surface temperature of the radiated object 60 is still much lower than the target temperature, the radiator body 10 emits at the highest possible power to heat the surface of the radiated object 60 as quickly as possible. If the surface temperature of the radiated object 60 is already close to the target temperature, the heating power of the radiator body 10 is adjusted according to, for example, a PID (Proportional-Integral-Differential) algorithm, thereby adjusting the radiation power of the radiator body 10 to the surface of the radiated object 60, so that the surface temperature of the radiated object 60 can gradually approach the target temperature and avoid overshoot. In this embodiment, the radiated object 60 can be a part of the human body surface. If the surface temperature of the radiated object 60 is already close to the target temperature, and the radiator body 10 still radiates energy to the surface of the radiated object 60 at a high power, it is very easy for the surface temperature of the radiated object 60 to exceed the target temperature in a short time (i.e., overshoot occurs), causing the human body to feel overheated, reducing user comfort, or even burning the skin.

[0059] In this embodiment, the characteristic parameters include at least the resistance of the radiator body 10. Since the heat generated by the radiator body 10 when energized is primarily due to its resistive characteristics, under the same input power, the change in the heat generated by the radiator body 10 is mainly affected by its own resistance. However, under prolonged use and other factors, the electrical characteristics of the radiator body 10 will gradually change. After each preheating, the characteristic parameters of the radiator body 10 are calculated based on the temperature rise after that preheating and used as control parameters to achieve more precise control over the heating power of the radiator body 10. This allows the surface temperature of the radiated object 60 to reach the target temperature faster and more accurately, improving the user experience. The storage module 80 is electrically connected to the processing unit 52. The characteristic parameters of the radiator body 10 calculated by the processing unit 52 are stored in the storage module 80 for subsequent retrieval.

[0060] In a preferred embodiment, the characteristic parameters also include the reactance, conductance, and / or susceptance of the radiator body 10. Since the radiator body 10 is typically in the form of a coil, its characteristic parameters exhibit characteristics of a non-purely resistive circuit. To more accurately describe the electrical characteristics of the radiator body 10 and improve the temperature control accuracy of the radiator body 10, the processing unit 52 can also calculate its characteristic parameters such as reactance, conductance, and susceptance based on the temperature rise of the radiator body 10 after preheating. When controlling the heating power of the radiator body 10, the processing unit 52 also uses the characteristic parameters such as reactance, conductance, and susceptance as control parameters, further improving the control accuracy of the heating power of the radiator body 10, enabling the surface temperature of the radiated object 60 to reach the target temperature faster and more accurately, thus improving the user experience.

[0061] In one embodiment, the power module 20 includes external mains power, i.e., the therapeutic device 1 is connected to external mains power for use as a power supply. In this embodiment, when the second temperature sensor 40 detects that the difference between the temperature of the irradiated object 10 and the target temperature value is greater than a preset value, i.e., when the surface temperature of the irradiated object 60 is much lower than the target temperature, the power supply capacity of the external mains power does not need to be considered. The processing unit 52 controls the power unit 51 to output power to the irradiator body 10 at the maximum power (i.e., the rated power of the radiator body 10) or a relatively large power (e.g., 90% rated power, 85% rated power, 80% rated power), and supplies power to the irradiator body 10 according to the maximum heat power that the irradiator body 10 can withstand, so that the surface temperature of the irradiated object 60 rises as quickly as possible.

[0062] The preset value of the difference between the temperature of the radiating object 10 and the target temperature can be set according to the actual situation, such as based on the maximum heating power of the radiated object 60 and the radiator body 10, and is not limited here.

[0063] In another embodiment, the power module 20 includes a battery, which supplies power to the therapeutic device 1. In this embodiment, the therapeutic device 1 does not need to be connected to an external mains power supply, improving its portability and allowing it to be used outdoors or in other situations. In this embodiment, the therapeutic device 1 is powered by a battery. When the second temperature sensor 40 detects that the difference between the temperature of the radiated body 10 and the target temperature is less than a preset value, the processing unit 52 is further configured to control the amount of power delivered by the power unit 51 to the radiator body 60 based on the remaining battery power and operating status parameters. That is, in this case, the processing unit 52 controls the power supply to the radiator body 10 based on a temperature control algorithm (e.g., a PID algorithm, or other temperature control algorithms, which are not limited here) and the remaining battery power and operating status parameters.

[0064] When the surface temperature of the radiated object 60 is significantly lower than the target temperature, i.e., when the second temperature sensor detects that the difference between the temperature of the radiated object and the target temperature is greater than a preset value, the processing unit 52, in addition to considering the maximum heat output power that the radiator body 10 can withstand, also needs to consider the battery's maximum power supply capacity to ensure the battery is in normal working condition and to prevent damage caused by excessive battery output power. In this embodiment, the processing unit 52 is also used to supply power to the radiator body 10 at the maximum power that the battery can output in its current state, based on the battery's remaining charge and operating status parameters. It comprehensively considers the battery's output capacity and the radiator body 10's withstand capacity when supplying power to the radiator body 10, in order to avoid damage to the battery due to excessive output current. Under the premise of ensuring safe battery operation, it supplies power to the radiator body 10 with the maximum possible output power, thereby extending the battery's lifespan.

[0065] Furthermore, when the power module 20 is a battery, the processing unit 52 is also directly connected to the battery to read its operating status parameters. These operating status parameters include at least one of battery temperature, output voltage, and output current.

[0066] like Figure 2 As shown, the present invention also provides a control method for a therapeutic device, the control method being used in the therapeutic device 1 as described above, the control method comprising:

[0067] The treatment device described above is provided; the processing unit controls the power supply module to supply power to the radiator body through the power unit. After the treatment device 1 is turned on, the radiator body 10 is preheated first under the set time and set voltage. Since the heat generated by the radiator body 10 when energized is mainly due to its resistive characteristics, under the same input power, the change in the heat generated by the radiator body 10 is mainly affected by its own resistance. However, under the influence of long-term use and other factors, the electrical characteristics of the radiator body 10 will gradually change. In this step, the radiator body 10 is preheated so that the temperature rise of the radiator body 10 during the preheating process can be used to determine whether the radiator body 10 can work normally.

[0068] The system utilizes a first temperature sensor to monitor the temperature of the radiator body before and after preheating and calculates the temperature rise. When the temperature rise is within the normal range, the processing unit obtains the characteristic parameters of the radiator body based on the temperature rise and stores these parameters in the storage module 80. These characteristic parameters are then used as control parameters to achieve more precise control over the heating power of the radiator body 10. This allows the surface temperature of the radiated object 60 to reach the target temperature more quickly and accurately, improving the user experience.

[0069] If the temperature rise of the radiator body 10 after preheating is not within the normal range, it indicates that the radiator body 10 is not working properly. In this case, a warning will be issued and the treatment device will be shut down.

[0070] Regarding the explanation of the normal range of temperature rise of the radiator body 10 after preheating, during the preheating process, the voltage and time for heating the radiator body 10 are fixed, and the heating characteristics of the radiator body 10 itself are also fixed. Therefore, the estimated temperature rise value of the radiator body 10 can be calculated based on the radiator body 10 and the time of voltage application. Then, some margin is reserved on both sides of the estimated temperature rise value to obtain the normal range of temperature rise value of the radiator body 10 after preheating.

[0071] A second temperature sensor monitors the temperature of the radiated object. When the difference between the radiated object's temperature and the target temperature is less than a preset value, indicating that the surface temperature of the radiated object 60 is close to the target temperature, the processing unit controls the power output to the radiator body based on the difference and the characteristic parameters of the radiator body. Using the characteristic parameters of the radiator body 10 as system characteristic parameters and the temperature deviation between the surface temperature of the radiated object 60 and the target temperature as the deviation input, a temperature control algorithm is used to finely adjust the heating power of the radiator body 10 based on the temperature deviation, continuously making fine adjustments. This ensures that the surface temperature of the radiated object 60 gradually approaches the target temperature, avoiding overshoot and improving the user experience.

[0072] The temperature control algorithm can be a PID algorithm or other control algorithms, and there are no restrictions here, as long as it can achieve temperature control of the radiator body 10.

[0073] In a preferred embodiment, before monitoring the temperature of the irradiated object 60 using the second temperature sensor, the method further includes: determining whether the processing unit 52 stores a target temperature value. The target temperature command is a user-input command, set according to the user's desired surface temperature of the irradiated object 60. If a user-inputted target temperature command has been stored, the process proceeds to the next step. If the processing unit 52 does not store a target temperature command, the therapeutic device 1 enters a standby state and waits for the target temperature command to be input. The target temperature command is a user-input command, set according to the user's desired surface temperature of the irradiated object 60.

[0074] When the therapeutic device 1 enters the standby state, since the first temperature sensor 30 and the second temperature sensor 40 do not monitor the temperature of the radiator body 10 and the surface of the radiated object 60, the radiator body 10 does not heat up and does not radiate energy outward, thus ensuring the safety of the therapeutic device 1 in the standby state and avoiding the occurrence of danger due to an unexpected increase in the temperature of the radiator body 10 or the surface of the radiated object 60.

[0075] In one embodiment, the power module is an external mains power supply; the power module 20 includes the external mains power supply, i.e., the therapeutic device 1 is connected to the external mains power supply for use as a power source. In the embodiment where the power module 20 includes the external mains power supply, the external mains power supply can be considered to have an unlimited power supply capacity for the heating power of the radiator body 10. When the second temperature sensor detects that the difference between the temperature of the radiated object and the target temperature value is greater than a preset value, only the maximum output power of the radiator body 10 needs to be considered. The processing unit controls the power unit to output power to the radiator body at maximum power according to the difference and characteristic parameters, so that the surface of the radiated object 60 can heat up to the target temperature as soon as possible.

[0076] In another embodiment, such as Figure 3 As shown, the present invention also provides another control method for a therapeutic device, wherein the power module is a battery. In embodiments where the power module 20 includes a battery, the therapeutic device 1 does not need to be connected to an external mains power supply, improving the portability of the therapeutic device 1 and enabling its use outdoors and in other situations. Since the radiator body 10 is powered by a battery, when the second temperature sensor detects that the difference between the detected value of the radiated object and the target temperature value is less than a preset value, the processing unit also controls the power supplied by the power unit to the radiator body based on the remaining battery power and operating status parameters. This prevents excessive battery output current or excessive battery temperature from causing battery damage, protecting the battery itself while ensuring that the temperature of the radiated object 60 reaches the set target value as quickly as possible.

[0077] When the second temperature sensor detects that the difference between the temperature of the radiated object and the target temperature is greater than a preset value, the processing unit, based on the remaining battery power and operating status parameters, delivers power to the radiator body at the maximum power that the battery can currently output. When the processing unit 52 controls the radiator body 10 to output at the current maximum power, it not only needs to consider the maximum output power of the radiator body 10, but also, to ensure the battery is in normal working condition and to avoid damage caused by excessive battery output power, it needs to consider the maximum output power that the battery can provide based on the battery's current condition. The more remaining battery power, the greater the power the battery can output. The maximum power coefficient of the battery is calculated based on the operating status parameters. The current maximum power is calculated based on the maximum output power of the radiator body 10 and the maximum power coefficient of the battery.

[0078] The battery's operating status parameters include at least one of the battery's temperature, output voltage, and output current. In embodiments where the power module 20 is a battery, the processing unit 52 is connected to the battery to enable the processing unit 52 to read the battery's operating status parameters. By collecting more dimensions of the battery's operating status parameters, the maximum power that the battery can output in the current state can be calculated more accurately. This maximizes the heating power of the radiator body 10 while ensuring that the battery is not damaged by excessive power output, allowing the surface temperature of the radiated object 60 to reach the target temperature more quickly and improving the user experience.

[0079] Collect more multi-dimensional operating status parameters of the battery to more accurately calculate the maximum power that the battery can output in the current state. While ensuring that the battery will not be damaged by excessive power output, maximize the heating power of the radiator body 10 so that the surface temperature of the radiated object 60 can reach the target temperature more quickly and improve the user experience.

[0080] In a preferred embodiment, the characteristic parameters also include the reactance, conductance, and susceptance of the radiator body 10. Since the radiator body 10 typically contains a coil, its characteristic parameters exhibit characteristics of a non-purely resistive circuit. To more accurately describe the electrical characteristics of the radiator body 10 and improve the temperature control accuracy, the processing unit 52 also calculates the reactance, conductance, and susceptance of the radiator body 10 based on the temperature rise during the preheating process. When controlling the heating power of the radiator body 10 based on the surface temperature of the radiated object 60, the reactance, conductance, and susceptance are also input as characteristic parameters, further improving the control accuracy of the heating power of the radiator body 10. This allows the surface temperature of the radiated object 60 to reach the target temperature more quickly and accurately, improving the user experience.

[0081] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
