Description

Technical Field

[0001] The utility model relates to the technical field of physical therapy equipment, in particular to a temperature-controlled physical therapy device. Background Art

[0002] There are many types of physiotherapy equipment on the market. The principle is to apply physical factors such as electricity, sound, light, magnetism, water, and pressure to the object of use to achieve the effect of physiotherapy. Among them, the most widely used is thermal therapy equipment. According to its working principle, it mainly includes short-wave and ultra-short-wave, microwave and infrared physiotherapy equipment. Taking the specific electromagnetic wave therapy device as an example, the specific electromagnetic wave therapy device is a medical device that uses the electromagnetic wave radiation effect (or thermal effect) for treatment. The main working principle is to use a heating component to heat the radiation plate containing the TDP element. The radiation plate is heated to generate a specific electromagnetic spectrum with a wavelength range of 2 to 25μm. The specific electromagnetic spectrum is used to radiate heat to the object of use and ultimately achieve a therapeutic effect.

[0003] When a user uses a physiotherapy device that achieves a physiotherapy effect through heat radiation, the user can often only determine the effect of the physiotherapy based on the temperature at the heat radiation location. The user relies on his or her own senses to feel the treatment effect, which is highly subjective, making it impossible for the user to clearly and intuitively feel the physiotherapy effect of the physiotherapy device. The physiotherapy equipment in the prior art also lacks relevant functions, resulting in a poor user experience during use. Utility Model Content

[0004] The utility model aims to provide a temperature-controlled physiotherapy device to solve the problem that the physiotherapy equipment in the prior art has a poor user experience when in use.

[0005] In order to solve the above problems, the utility model adopts the following technical solution: a temperature control physiotherapy device, comprising:

[0006] Physiotherapy devices generate electromagnetic waves of a specific frequency through thermal radiation to act on the object of use to achieve a physiotherapy effect;

[0007] A temperature detection module is used to detect the temperature value of the location where the object is radiated with heat and generate a temperature detection signal;

[0008] A control module, used for receiving a temperature detection signal and generating a temperature imaging signal according to the temperature detection signal;

[0009] The thermal imaging module is used to receive the temperature imaging signal and display the thermal map of the location where the object is radiated with heat.

[0010] The principle and beneficial effects of this scheme are as follows: in this application, the physiotherapy device is used to radiate heat to the physiotherapy position of the user, and the physiotherapy position receives the electromagnetic waves of a specific frequency generated by the thermal radiation and is treated. As the physiotherapy at the thermal radiation position proceeds, the temperature of the radiated area continues to rise, and the temperature detection module detects the temperature value of the thermal radiation position and converts the detected temperature value into a temperature detection signal. After receiving the temperature detection signal, the control module generates a temperature imaging signal and transmits the temperature imaging signal to the thermal imaging module. The thermal imaging module is used to display the temperature condition of the thermal radiation position in real time in the form of a thermal map, so that the user can intuitively and clearly see the temperature value of the thermal radiation position at any time, and as the thermal radiation therapy proceeds, the temperature of the physiotherapy area continues to rise, and the color of the thermal map changes accordingly. The user can more intuitively feel the temperature changes during the physiotherapy process, thereby enhancing the fun and authenticity of the use of the physiotherapy device, thereby effectively improving the user experience.

[0011] Preferably, as an improvement, it also includes a user input module, which is used to set a predetermined temperature value for the thermal radiation therapy position; the user input module is connected to the control module signal, and the control module controls the output power of the therapy device according to the difference between the detected temperature value and the predetermined temperature value.

[0012] In the present solution, the control module can not only convert the received temperature detection signal into a temperature imaging signal, so that the thermal imaging module can form and display a thermal map of the heat radiation position; at the same time, in the present solution, by setting a user input module, the temperature value of the position to be heat radiated can be pre-set. For example, if the position to be heat radiated is the hand of the user, the predetermined temperature value can be set to 40°C. When the temperature detection module measures the real-time temperature of the hand as 34°C at the beginning of the heat radiation, the control module controls the output power of the physiotherapy device according to the difference between the predetermined temperature value and the detected temperature value (i.e., a 6°C difference), so that the physiotherapy device can raise the temperature of the heat radiation position to the preset temperature value with appropriate power and the fastest speed, changing the existing method of manually adjusting the power of the physiotherapy device, effectively reducing the difficulty of operation for the user, and being able to automatically complete temperature detection and temperature control, realizing two-way closed-loop control, and improving the accuracy of temperature control, the safety of the use of the device, and the physiotherapy effect of the physiotherapy device.

[0013] Preferably, as an improvement, the physiotherapy device is provided with a heating radiation component for producing thermal radiation treatment effects, the control module signal is connected to the temperature output control module, and the temperature output control module is connected to the heating radiation component signal to control the output power of the heating radiation component.

[0014] In this solution, the heating radiation component is used to perform thermal radiation therapy on the therapy position of the user. The signal on the control module is connected to the temperature output control module, and the temperature output control module is used to adjust and control the output power of the heating radiation component, so that the output power of the heating radiation component can be accurately and efficiently controlled and adjusted, effectively improving the therapy effect.

[0015] Preferably, as an improvement, the temperature detection module includes a non-contact temperature sensor.

[0016] In this solution, the temperature detection module adopts a non-contact temperature sensor, so that when the temperature detection module detects the heat radiation position, it does not need to contact the physical therapy part of the user, thereby avoiding the temperature detection module from blocking the heat radiation effect of the physical therapy device, effectively ensuring the physical therapy effect of the physical therapy device.

[0017] Preferably, as an improvement, the non-contact temperature sensor includes a thermal imaging sensor; the control module is used to receive the temperature detection signal of the thermal imaging sensor, and generate a temperature adjustment signal and a temperature imaging signal according to the temperature detection signal, the temperature output control module receives the temperature adjustment signal to adjust the power of the physiotherapy device, and the thermal imaging module displays a thermal map after receiving the temperature imaging signal.

[0018] In this solution, after the control module receives the temperature detection signal, it generates a temperature adjustment signal and a temperature imaging signal through calculation, etc. according to the predetermined temperature value set by the user input module, so that the temperature output control module can automatically adjust according to the temperature adjustment signal, and the thermal imaging module can display the thermal map of the treatment position according to the temperature imaging signal.

[0019] Preferably, as an improvement, the pixel infrared array of the thermal imaging sensor is smaller than 320*240.

[0020] Although the pixel infrared array of the traditional thermal imaging sensor is large, the large number of pixels and high resolution make the thermal map more accurate and vivid, but the cost of the traditional thermal imaging sensor is very high, while the cost of the existing physiotherapy device is low, so it is not practical to use the traditional high-cost thermal imaging sensor directly on the physiotherapy device. In this solution, the pixel infrared array of the thermal imaging sensor is less than 320*240, which makes the structure of the thermal imaging sensor simpler, smaller in size and greatly reduces the cost. The user's demand in this solution is to intuitively understand the physiotherapy effect of the thermal radiation position. Therefore, in the case of a smaller pixel, the user can also clearly and intuitively view and feel the physiotherapy effect of the physiotherapy device through the thermal map.

[0021] Preferably, as an improvement, the temperature detection range of the thermal imaging sensor is -40°C-80°C.

[0022] In this solution, the temperature detection range of the thermal imaging sensor is -40℃-80℃, which has a wide detection range and is suitable for the application range of the physiotherapy device.

[0023] Preferably, as an improvement, the thermal imaging module includes a display screen connected to the control module signal.

[0024] In this solution, a display screen is used to display a thermal map of the heat radiation position, and the user can conveniently view it through the display screen, so that the user has a better user experience.

[0025] Preferably, as an improvement, the display screen is fixedly connected to the physiotherapy apparatus, and the user input module is fixedly connected to the display screen.

[0026] In this solution, the display screen is fixedly connected to the physiotherapy apparatus, and the user input module is fixedly connected to the display screen, so that the user can conveniently set the predetermined temperature value and view the thermal map conveniently.

[0027] Preferably, as an improvement, the physiotherapy device includes an infrared therapy device or a specific electromagnetic wave therapy device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is further described in detail through specific implementation methods:

[0034] The reference numerals in the drawings of the specification include: physiotherapy device 1, thermal imaging sensor 2, display screen 3, physiotherapy position 4.

[0035] Embodiment 1

[0036] This embodiment is as shown in the attached Figure 1As shown: A temperature-controlled physiotherapy device, including a physiotherapy instrument 1, a temperature detection module, a control module and a thermal imaging module, wherein the physiotherapy instrument 1 is used to generate electromagnetic waves of a specific frequency through thermal radiation to act on the physiotherapy position 4 of the user to achieve a physiotherapy effect. Specifically, the physiotherapy instrument 1 in this embodiment can refer to an infrared therapy instrument, a specific electromagnetic wave therapy device and other physiotherapy equipment that achieves a physiotherapy effect through thermal radiation. Therefore, the physiotherapy instrument 1 in this embodiment is at least provided with a heating radiation component for generating a thermal radiation therapy effect, such as an infrared therapy instrument including an infrared heating lamp, etc., and a specific electromagnetic wave therapy device including a heating lamp and a TDP radiation plate, etc., which are not listed here one by one. In addition, the user in this embodiment includes but is not limited to humans, etc., and the physiotherapy position 4 may include a person's hands, wrists, legs, waist, etc., which are not listed here one by one.

[0037] The temperature detection module is used to detect the detected temperature value of the position where the object is radiated by heat, and generate a temperature detection signal. The temperature detection module in this embodiment includes a non-contact temperature sensor, so that the temperature detection module does not need to contact the object when measuring the temperature of the physiotherapy position 4, thereby avoiding the temperature detection module from blocking the physiotherapy effect of the physiotherapy device 1 and affecting the physiotherapy effect. Specifically, the non-contact temperature sensor in this embodiment adopts a thermal imaging sensor 2, and the resolution of the thermal imaging sensor 2 is less than 320*240. Since the resolution of the thermal imaging sensor 2 is much smaller than the thermal imaging sensor with high sampling rate and high pixel resolution in the prior art, the thermal imaging sensor 2 in this embodiment is small in size and low in cost, and can be conveniently and economically applied to the temperature detection of the physiotherapy device 1 whose equipment cost itself is not high, such as the far-infrared thermal temperature sensor (32×24, 768 pixels) of the brand Melexis and model MLX90640, or the infrared array sensor of the brand Panasonic and model AMG8833 (8×8, 64 pixels).

[0038] The control module is used to receive the temperature detection signal generated by the temperature detection module and generate a temperature imaging signal according to the received temperature detection signal; the thermal imaging module is used to receive the temperature imaging signal and form and display a thermal image of the thermal radiation therapy position 4 of the object according to the temperature imaging signal. The thermal imaging module includes a display screen 3 connected to the control module signal, combined with Figure 3 The display screen 3 can receive the temperature imaging signal and display the thermal map of the therapy position 4. In order to facilitate the user to view the thermal map status, the display screen 3 is fixedly connected to the therapy device 1 in this embodiment, so that the user can view the thermal map status of the therapy position 4 in real time through the display screen 3 during the operation of the therapy device 1.

[0039] Since the resolution of the thermal imaging sensor 2 used in this embodiment is very small, the resolution of the source image of the thermal image generated by the thermal imaging sensor 2 detecting the treatment position 4 is very small. If the source image with a relatively small resolution is directly transmitted to the display screen 3 for display, the resolution of the thermal image on the display screen 3 will be low and the image will not be clear. For example, in this embodiment, a far-infrared thermal temperature sensor of model MLX90640 is used, and its detection pixel value is 768 pixels, while the display resolution of the display screen 3 is 320*240 (i.e., 76800 pixels). When the temperature thermal imaging signal is transmitted to the display screen 3, the pixels displayed on the display screen 3 are relatively low, which affects the user experience.

[0040] Therefore, in this embodiment, the control module adopts MCU (i.e., microprocessor), and the control module can not only receive the temperature detection signal, but also can amplify the source image after receiving the temperature detection signal (i.e., the above-mentioned source image), so that the resolution of the source image after amplification is equal to the resolution of the display terminal. Specifically, the controller can use the nearest interpolation algorithm, bilinear interpolation algorithm, or bicubic interpolation algorithm to amplify the source image to obtain a target image adapted to the resolution of the display screen 3. In this embodiment, based on cost and compatibility factors, the controller uses a bilinear interpolation algorithm to amplify the source image. The processing method can refer to the video image amplification method based on a bilinear interpolation algorithm disclosed in the invention name CN110223232A to amplify the source image, so that the resolution of the source image after amplification is equal to the resolution of the display screen 3.

[0041] The specific implementation process is as follows:

[0042] During use, the heating radiation component in the physiotherapy device 1 performs thermal radiation therapy on the physiotherapy position 4 of the user. During the physiotherapy process, the temperature of the physiotherapy position 4 continues to rise, and during the physiotherapy process, the thermal imaging sensor 2 detects the temperature value of the physiotherapy position 4 in real time to generate a temperature detection signal, and then transmits the temperature detection signal to the control module. After receiving the temperature detection signal, the control module amplifies the source image and then generates a temperature imaging signal (that is, the target image with a resolution equal to the resolution of the display screen 3 after the source image is amplified), and transmits the temperature imaging signal to the display screen 3. After receiving the temperature imaging signal, the display screen 3 displays a thermal map of the physiotherapy position 4.

[0043] Since the temperature of the therapy position 4 continues to rise during the therapy, the user can not only feel the continuous increase in temperature of the therapy position 4 through his or her own senses; at the same time, the user can also view the thermal map of the therapy position 4 in real time through the display screen 3, and as the therapy continues, especially when the temperature of the therapy position 4 continues to rise after the start of the therapy, the user can intuitively see the image changes of the thermal map of the therapy position 4, thereby more recognizing the therapy effect of the therapy device 1 and enhancing the experience during the use of the therapy device 1.

[0044] Embodiment 2

[0045] The difference between the second embodiment and the first embodiment is that in this embodiment, a user input module is connected to the therapy device 1, and the user input module is used to set the predetermined temperature value of the thermal radiation therapy position 4. Figure 4 As shown, the user input module is integrated on the display screen 3, and the user input module is connected with the control module signal. Specifically, the user input module includes a control button set on the display screen 3, and the control button includes at least a switch button, a temperature increase button, a temperature decrease button and a confirmation button, wherein the switch button is used to control the start or close of the user input module, the temperature increase button is used to control the increase of the predetermined temperature value, the temperature decrease button is used to control the decrease of the predetermined temperature value, and the confirmation button is used to determine the set predetermined temperature value. In actual operation, the user input module can be started by the switch button first, and then the predetermined temperature value can be set by the temperature increase button or the temperature decrease button. For example, when the user input module is turned on, the default predetermined temperature value is 40°C, and the actual predetermined temperature value to be set is 43°C. At this time, the temperature increase button can be pressed to increase the predetermined temperature value. Each time the predetermined temperature value is pressed, it increases by 0.5°C. After six times, when the predetermined temperature value is displayed on the display screen 3 as 43°C, press the confirmation button again to complete the setting of the predetermined temperature value.

[0046] In this embodiment, the control module signal is connected to the temperature output control module, and the temperature output control module is connected to the heating radiation component signal to control the output power of the heating radiation component. Specifically, after receiving the temperature detection signal, the control module not only generates a temperature imaging signal, but also automatically adjusts the output power of the heating radiation component according to the value of the temperature detection signal and the predetermined temperature value, so that the heating radiation component allows the physiotherapy position 4 to reach the predetermined temperature value at the most appropriate power adjustment speed. In this embodiment, the control module uses a PID algorithm to adjust the power of the heating radiation component, and its adjustment formula is as follows:

[0047] ,

[0048] in:

[0049] OUT is the control amount of the heating radiation component by MCU;

[0050] Kp is a proportional control constant, and in this embodiment, the value range is 10 to 20, preferably Kp=15;

[0051] Ek is the difference between the current detected temperature and the preset temperature;

[0052] Ek-1 is the difference between the last detected temperature and the preset temperature;

[0053] Ki is the integral control constant, and in this embodiment, the value range is 0.1 to 0.5, preferably Ki=0.3;

[0054] K is the running time length of the integration algorithm;

[0055] Kd is a differential control constant, and in this embodiment, the value range is 1 to 50, preferably Kd=30;

[0056] Out0 is a constant to avoid 0 output.

[0057] In the present embodiment, by setting a user input module and a temperature output control module, not only can the physiotherapy device display the thermal map of the physiotherapy position 4 in real time, but also the predetermined temperature value can be manually set through the user input module, so as to set the appropriate physiotherapy temperature according to different physiotherapy positions 4, thereby achieving better physiotherapy effects; in addition, in the present embodiment, after the user or operator sets the predetermined temperature value, the control module can automatically determine the heating control amount of the heating power of the heating radiation component according to the temperature detection signal of the thermal imaging sensor 2 and the set predetermined temperature value, so that the heating radiation component can heat the physiotherapy position 4 to the set predetermined temperature value with the most appropriate power and the fastest speed, which is more accurate and efficient than the manual power adjustment method of the physiotherapy device 1 in the prior art, thereby realizing precise closed-loop control and ultimately achieving the purpose of better physiotherapy effects.

[0058] Embodiment 3

[0059] The difference between the third embodiment and the first embodiment is that in the first embodiment, the thermal imaging module is a display screen 3, such as Figure 5 As shown, in this embodiment, the thermal imaging module not only includes a display screen 3, but also includes smart terminals such as smart phone terminals and computer terminals connected by signals. For example, a smart phone can be connected by signals using Bluetooth or WiFi, which can not only display the thermal map in real time, but also store the physical therapy process data.

[0060] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
