Description

Technical Field

[0001] The present application relates to the field of temperature measurement technology, and in particular to a temperature measurement method, device, temperature-controlled radiofrequency therapeutic device, and storage medium. Background Art

[0002] The radio frequency waves emitted by the temperature-controlled radio frequency device can enter the subcutaneous tissue. Under the influence of the radio frequency waves, the natural resistance of the subcutaneous tissue can produce a thermal effect, thereby stimulating the healing response of degenerated cells and achieving the effect of wrinkle removal and skin tightening.

[0003] However, temperature-controlled radiofrequency therapy devices require a temperature sensor to heat the skin to a set temperature. This temperature sensor is located on the back of the electrode sheet, and the front is in close contact with the skin through a silicone membrane for heating. This is also known as a built-in temperature sensor. Because the built-in temperature sensor measures skin temperature indirectly through heat conduction, it cannot directly measure skin temperature, resulting in inaccurate temperature measurements.

[0049] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0050] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0051] In the existing technology, dermal collagen fibers will immediately contract at a certain temperature, causing the dermis to rebuild and thicken. Therefore, after the temperature-controlled radio frequency therapy device emits radio frequency waves into the subcutaneous tissue, the natural resistance of the subcutaneous tissue moves under the influence of the radio frequency waves to produce a thermal effect. The thermal effect produced will cause the collagen to denature, causing the collagen fibers to contract, stimulating the healing response of the degenerated cells, tightening the loose skin, and proliferating collagen. The new collagen will reshape and repair the aged and damaged collagen, thereby achieving the effect of wrinkle removal and skin tightening.

[0052] Since the temperature-controlled radiofrequency therapeutic device 10 needs to use a temperature sensor 11 to heat the skin to the target temperature, the temperature sensor is set on one side of the electrode sheet 12, and the other side of the electrode sheet is provided with a silicone membrane 13, which is in close contact with the skin, i.e., it is constructed as a built-in temperature sensor. The radio frequency waves emitted by the temperature-controlled radiofrequency therapeutic device 10 can penetrate the metal electrode sheet 12 and act on the skin surface 1. The skin surface 1 then transmits the temperature through the electrode sheet 12 to the built-in temperature sensor. Figure 1 Because the skin temperature measured by the built-in temperature sensor is indirectly measured through heat conduction, some heat can be offset by external or internal factors during the heat conduction process. For example, if the electrodes in a temperature-controlled RF therapy device are not heating electrodes, the electrodes themselves will dissipate some heat. Alternatively, if the ambient temperature during use is low, some of the heat generated by the skin will be dissipated by the external environment before heat conduction can occur. Therefore, when skin temperature cannot be directly measured, the actual temperature collected by the built-in temperature sensor is inaccurate.

[0053] The present application provides a solution. Compared with the prior art, the built-in temperature sensor in the temperature-controlled radiofrequency therapeutic device indirectly collects skin temperature through heat conduction. Based on the measured temperature collected by the built-in temperature sensor, the target temperature of the temperature-controlled radiofrequency therapeutic device is determined from multiple candidate fitting temperature models to determine the target temperature. Finally, a temperature correction value is determined based on the target fitting temperature model, and the measured temperature is corrected according to the temperature correction value. The candidate fitting temperature model in the present application is constructed based on the difference between the first display temperature and the target temperature and the second display temperature, and the second display temperature is collected by the external temperature sensor in direct contact with the skin, not by heat conduction, and the temperature collected by it is more accurate. Therefore, after determining the target temperature and the measured temperature of the temperature-controlled radiofrequency therapeutic device, the present application determines the corresponding temperature correction value based on the corresponding target fitting temperature model. The temperature correction value is used as the heat lost by the built-in temperature sensor in the process of indirectly collecting the skin temperature through heat conduction, so that the temperature measured by the built-in temperature sensor in the temperature-controlled radiofrequency therapeutic device is closer to the skin temperature, thereby improving the accuracy of the measured temperature.

[0054] Reference Figure 2 , Figure 2 This is a schematic diagram of the structure of the temperature measurement device of the hardware operating environment involved in the embodiment of the present application.

[0055] like Figure 2 As shown, the temperature measurement device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 1003 may optionally include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art will understand that Figure 2The structure shown in the figure does not constitute a limitation to the temperature measuring device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0057] like Figure 2 As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module and a temperature measurement program.

[0058] exist Figure 2 In the temperature measurement device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the temperature measurement device of the present application can be set in the temperature measurement device, and the temperature measurement device calls the temperature measurement program stored in the memory 1005 through the processor 1001 and executes the temperature measurement method provided in the embodiment of the present application.

[0059] Based on the hardware structure of the above temperature measurement device but not limited to the above hardware structure, the present application provides a first embodiment of a temperature measurement method. Figure 3 , Figure 3 A flow chart of a first embodiment of a temperature measurement method is shown.

[0060] It should be noted that although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0061] In this embodiment, the temperature measurement method includes:

[0062] Step S10: obtaining the target temperature of the temperature-controlled radiofrequency therapeutic apparatus and the actual temperature collected by the built-in temperature sensor in the temperature-controlled radiofrequency therapeutic apparatus.

[0063] It should be noted that the temperature measurement method is executed by a temperature-controlled radiofrequency therapeutic instrument, which stores a temperature measurement program. When the temperature-controlled radiofrequency therapeutic instrument executes the temperature measurement program, the temperature measurement method in this embodiment is implemented.

[0064] In this embodiment, the target temperature may be a preset target temperature in the temperature-controlled radiofrequency therapeutic device, or may be a temperature defined by the user according to his or her own needs.

[0065] Specifically, after the temperature-controlled RF therapy device is activated according to the target temperature, it outputs radio frequency waves. The natural electrical resistance of the subcutaneous tissue generates a thermal effect under the action of the radio frequency waves, thereby increasing the skin temperature. Because the temperature-controlled RF therapy device is in close contact with the skin surface, when the skin temperature rises, the heat from the skin surface can be transferred to the temperature-controlled RF therapy device through heat conduction. The built-in temperature sensor inside the temperature-controlled RF therapy device collects the temperature collected by heat conduction as the actual measured temperature.

[0066] In this embodiment, the user can set the target temperature of the temperature-controlled radio frequency therapeutic device by interacting with virtual buttons and / or a virtual keyboard in the temperature-controlled radio frequency therapeutic device, and control the temperature-controlled radio frequency therapeutic device to output radio frequency waves according to the target temperature. While the temperature-controlled radio frequency therapeutic device is outputting radio frequency waves, the built-in temperature sensor in the temperature-controlled radio frequency therapeutic device also collects the temperature of the skin surface, i.e., the actual temperature collected by the built-in temperature sensor. The processor of the temperature-controlled radio frequency therapeutic device receives the actual temperature collected by the built-in temperature sensor.

[0067] Step S20: Determine a target fitting temperature model corresponding to the target temperature from a plurality of candidate fitting temperature models.

[0068] Among them, the candidate fitting temperature model is constructed based on the first temperature difference absolute value between the first apparent temperature collected by the built-in temperature sensor and the target temperature, and the second temperature difference absolute value between the first apparent temperature and the second apparent temperature collected by the external temperature sensor; any two candidate fitting temperature models are targeted at different preset target temperatures.

[0069] In this embodiment, the to-be-selected fitting temperature model may be a fitting temperature three-dimensional model constructed according to the first temperature difference absolute value and the second temperature difference absolute value.

[0070] Therefore, in order to facilitate the subsequent rapid determination of the target fitting temperature model corresponding to the target temperature, further, as an optional implementation, before step S20, the method further includes:

[0071] Step S11: After the operating temperature of the temperature-controlled radiofrequency therapeutic apparatus is configured to be a preset target temperature, the temperature-controlled radiofrequency therapeutic apparatus is started.

[0072] Step S12: Acquire a first apparent temperature collected by the built-in temperature sensor and a second apparent temperature collected by the external temperature sensor.

[0073] Step S13: Determine a first absolute value of a temperature difference between the preset target temperature and the first display temperature.

[0074] Step S14: Obtain a temperature change rate based on the first temperature difference absolute value, the first temperature difference absolute value at the previous moment, and a temperature sampling time interval.

[0075] Step S15: Determine fitting input data based on the first temperature difference absolute value and the temperature change rate.

[0076] Step S16: Determine a second absolute value of the temperature difference based on the first apparent temperature and the second apparent temperature.

[0077] Step S17: determining the fitting output data based on the absolute value of the second temperature difference.

[0078] Step S18: generating the candidate fitting temperature model based on the fitting input data and the fitting output data.

[0079] In this embodiment, the external temperature sensor may be a thermocouple.

[0080] Specifically, before starting the temperature-controlled radiofrequency therapeutic apparatus, the external temperature sensor 20 can be set between the electrode sheet 12 and the silicone membrane 13, as shown in FIG. Figure 4 When the temperature-controlled radiofrequency therapeutic device is started and is in close contact with the skin surface 1, the external temperature sensor 20 can directly collect the skin temperature, that is, the second apparent temperature.

[0081] In this embodiment, the temperature sampling time interval can be the time interval for collecting the first displayed temperature collected by the built-in temperature sensor and the second displayed temperature collected by the external temperature sensor, which is set according to actual needs, such as collecting the first displayed temperature displayed by the built-in temperature sensor and the second displayed temperature displayed by the external temperature sensor every two minutes.

[0082] Specifically, after configuring the working temperature of the temperature-controlled radiofrequency therapeutic device to the preset target temperature, the temperature-controlled radiofrequency therapeutic device is started, and the start time of the temperature-controlled radiofrequency therapeutic device is used as the starting time. According to the temperature sampling time interval, multiple temperature collection moments are determined, and the first apparent temperatures collected by the built-in temperature sensor at different temperature collection moments are collected. After obtaining the first apparent temperatures at different temperature collection moments, the absolute value of the first temperature difference between each first apparent temperature and the preset target temperature is calculated, and based on any two adjacent temperature collection moments t1 and temperature collection moments t2, the first absolute value of the temperature difference at the temperature collection moment t1 and the first absolute value of the temperature difference at the temperature collection moment t2 are calculated, wherein the time point corresponding to the temperature collection moment t1 is less than the time point corresponding to the temperature collection moment t2. After obtaining the first absolute value of the temperature difference at the temperature collection moment t1 and the first absolute value of the temperature difference at the temperature collection moment t2, the temperature change rate is obtained based on the first absolute value of the temperature difference at the temperature collection moment t1, the first absolute value of the temperature difference at the temperature collection moment t2, and the temperature sampling time interval. Furthermore, after calculating the temperature change rate, fitting input data is determined based on the absolute value of the first temperature difference at temperature acquisition time t2 and the temperature change rate. Furthermore, the absolute value of the second temperature difference is determined based on the second displayed temperature acquired by the external temperature sensor at temperature acquisition time t2 and the first displayed temperature. This second temperature difference absolute value is used as fitting output data. After obtaining the fitting input data and fitting output data, the Matlab fitting tool cftool can be used to generate a candidate fitting temperature model based on the fitting input data and fitting output data.

[0083] It is understandable that in order to avoid the situation where the power of the radio frequency waves output by the temperature-controlled radio frequency therapeutic device is too low, so that the thermal effect generated by the natural resistance movement of the subcutaneous tissue cannot reach the minimum temperature for the collagen fibers in the dermis to contract, resulting in failure of dermal reconstruction and thickening; or the radio frequency waves output by the temperature-controlled radio frequency therapeutic device are too high in power, causing burns to the user's skin. Therefore, the minimum and maximum temperatures of the temperature-controlled radio frequency therapeutic device can be pre-configured in the temperature-controlled radio frequency therapeutic device. Multiple preset target temperatures can be set between the maximum and minimum temperatures, and the temperature differences between the preset target temperatures can be equal.

[0084] Therefore, as an optional embodiment, the temperature difference between the preset target temperatures is T4, and T4 satisfies the following conditions: 1°C ≤ T4 ≤ 10°C. To avoid excessively small or large temperature differences between the target preset temperatures, preferably, T4 satisfies the following conditions: 2°C ≤ T4 ≤ 5°C. It should be noted that in actual applications, manufacturers of temperature-controlled radiofrequency therapeutic devices may adjust the temperature difference according to actual needs, and this embodiment does not limit this.

[0085] For example, assuming that the minimum temperature of the temperature-controlled radiofrequency therapeutic device is 40°C and the maximum temperature is 61°C, multiple preset target temperatures can be set in the temperature-controlled radiofrequency therapeutic device according to a temperature difference of 3°C, that is, the multiple preset target temperatures are 43°C, 46°C, 49°C, 52°C, 55°C, and 58°C respectively.

[0086] It should be noted that when the radio frequency waves output by a temperature-controlled radio frequency therapeutic device act on the skin, the skin temperature within the active area may vary. For example, at the edge of the active area, which is the boundary between the area where the thermal effect is generated and the area where the thermal effect is not generated, the temperature of the edge is necessarily lower than that of the center of the active area. Therefore, in order to make the collected second apparent temperature more accurate, further, as an optional embodiment, the second apparent temperature is the average temperature of the actual temperatures collected by multiple external temperature sensors.

[0087] Step S30: inputting the absolute value of the temperature difference between the target temperature and the measured temperature into a target fitting temperature model to determine a temperature correction value.

[0088] That is, the absolute value of the temperature difference between the measured temperature and the target temperature is input into the target fitting temperature model, and the target fitting temperature model maps the first temperature difference absolute value corresponding to the temperature difference absolute value to the second temperature difference absolute value as the predicted temperature correction value.

[0089] It is understandable that the user can set the target temperature of the temperature-controlled radiofrequency therapeutic device according to the tolerance of his or her skin, and the target temperature set by the user may not be the same as at least one of the preset target temperatures corresponding to the multiple candidate fitting temperature models. In this case, in order to determine the temperature correction value of the built-in temperature sensor at the target temperature set by the user, further, as an optional embodiment, step S30 specifically includes:

[0090] Step S301: Determine whether the target temperature is the same as at least one of the preset target temperatures corresponding to multiple candidate fitting temperature models.

[0091] Step S302: If the target temperature is not the same as at least one of the preset target temperatures corresponding to the multiple candidate fitting temperature models, determine a first preset target temperature adjacent to the target temperature and lower than the target temperature, and a second preset target temperature adjacent to the target temperature and higher than the target temperature.

[0092] Step S303: determining a temperature correction value based on a first fitting temperature model corresponding to the first preset target temperature and a second fitting temperature model corresponding to the second preset target temperature.

[0093] Specifically, after obtaining the target temperature of the temperature-controlled radiofrequency therapeutic device, the temperature measuring device determines, based on the target temperature, whether there is a preset target temperature that is the same as the target temperature among the preset target temperatures corresponding to the multiple candidate fitting temperature models. When there is no preset target temperature that is the same as the target temperature among the preset target temperatures corresponding to the multiple candidate fitting temperature models, a preset target temperature that is adjacent to the target temperature and less than the target temperature, i.e., a first preset target temperature, and a preset target temperature that is adjacent to the target temperature and greater than the target temperature, i.e., a second preset target temperature, are determined from the multiple preset target temperatures. The first fitting temperature model corresponding to the first preset target temperature and the second fitting temperature model corresponding to the second preset target temperature are determined. Finally, a temperature correction value is determined based on the first temperature fitting model and the second temperature fitting model.

[0094] Further, as an optional implementation, step S303 specifically includes:

[0095] Step S3031: determining a temperature correction value based on the first fitting temperature model, the second fitting model, and Formula 1;

[0096] Among them, formula 1 includes:

[0097] T_ERR_ESTIMATE=T_ERR_ESTIMATE1×(T1-T2) / (T3-T2)+(T_ERR_ESTIMATE2×(T3-T1) / (T 3-T2);

[0098] Among them, T_ERR_ESTIMATE is the temperature correction value, T_ERR_ESTIMATE1 is the fitting output data of the first fitting temperature model, T_ERR_ESTIMATE2 is the fitting output data of the second fitting temperature model, T1 is the target temperature, T2 is the first preset target temperature, and T3 is the second preset target temperature.

[0099] Specifically, for ease of understanding, a specific example is provided.

[0100] Assuming that the multiple preset target temperatures of the temperature-controlled radiofrequency therapeutic device are 40℃, 43℃, 46℃, 49℃, 52℃, 55℃, 58℃, and 61℃, it can be determined that the temperature-controlled radiofrequency therapeutic device corresponds to eight candidate fitting temperature models, namely, candidate fitting temperature model one with a preset target temperature of 40℃, candidate fitting temperature model two with a preset target temperature of 43℃, candidate fitting temperature model three with a preset target temperature of 46℃, candidate fitting temperature model four with a preset target temperature of 49℃, candidate fitting temperature model five with a preset target temperature of 52℃, candidate fitting temperature model six with a preset target temperature of 55℃, candidate fitting temperature model seven with a preset target temperature of 58℃, and candidate fitting temperature model eight with a preset target temperature of 61℃. When the target temperature is 42°C, it can be determined that there is no candidate fitting temperature model corresponding to 42°C among the multiple candidate fitting temperature models. At this time, it can be determined that the preset target temperature that is close to the target temperature and less than the target temperature is used as the first preset target temperature, that is, 40°C is used as the first preset target temperature, and the candidate fitting temperature model 1 is used as the first candidate fitting temperature model. The preset target temperature that is close to the target temperature and greater than the target temperature is used as the second preset target temperature, that is, 43°C is used as the second preset target temperature, and the candidate fitting temperature model is used as the second candidate fitting temperature model. Finally, based on formula 2, the corrected temperature is determined, that is, T_ERR_ESTIMATE=T_ERR_ESTIMATE1×(42-40) / (43-40)+(T_ERR_ESTIMATE2×(43-42) / (43-40).

[0101] It is understandable that the user may also select a preset target temperature from multiple preset target temperatures of the temperature-controlled radiofrequency therapeutic device as the target temperature. When the target temperature is one of the multiple preset target temperatures, further, as an optional embodiment, after step S301, the following is further included:

[0102] Step S304: If the target temperature is the same as at least one of the preset target temperatures corresponding to the multiple candidate fitting temperature models, a target fitting temperature model having the same preset target temperature as the target temperature is determined.

[0103] Step S305: Determine target fitting output data of the target fitting temperature model.

[0104] Step S306: Determine the temperature correction value based on the target fitting output data.

[0105] Specifically, when the target temperature is the same as at least one of the preset target temperatures corresponding to the multiple candidate fitting temperature models, a preset target temperature that is the same as the target temperature is determined, and the temperature fitting model corresponding to the preset target temperature is used as the target fitting temperature model. Target fitting output data of the target fitting temperature model is determined, and the target fitting output data is used as a temperature correction value to correct the measured temperature.

[0106] Alternatively, further, as an optional embodiment, when the target temperature is the same as at least one of the preset target temperatures corresponding to multiple to-be-selected fitting temperature models, the preset target temperature that is the same as the target temperature is used as the target temperature, and from the multiple preset target temperatures, a preset target temperature adjacent to the target temperature and less than the target temperature is determined, that is, the third preset target temperature, and a preset target temperature adjacent to the target temperature and greater than the target temperature, that is, the fourth preset target temperature, are determined, and the third fitting temperature model corresponding to the third preset target temperature and the fourth fitting temperature model corresponding to the fourth preset target temperature are determined, and finally, the temperature correction value is determined based on the third temperature fitting model, the fourth fitting temperature model and the above formula one.

[0107] Step S40: Correct the measured temperature based on the temperature correction value to obtain a corrected temperature.

[0108] In this embodiment, after the temperature correction value is determined, the measured temperature can be corrected based on the temperature correction value, the measured temperature, and Formula 2 to obtain a corrected temperature.

[0109] Specifically, Formula 2 is C_T=M_T+T_ERR_ESTIMATE, where C_T is the corrected temperature, M_T is the measured temperature, and T_ERR_ESTIMATE is the temperature correction value.

[0110] In this embodiment, after determining the target temperature of the temperature-controlled radiofrequency therapeutic device, a target fitting temperature model corresponding to the target temperature is determined from a plurality of candidate fitting temperature models according to the target temperature, and finally a temperature correction value is determined according to the target fitting temperature model, and the measured temperature is corrected according to the temperature correction value. The candidate fitting temperature model in this embodiment is constructed based on the difference between the first display temperature and the target temperature and the second display temperature, and the second display temperature is collected by an external temperature sensor in direct contact with the skin, not by heat conduction, and the temperature collected is more accurate. Therefore, after determining the target temperature and the measured temperature of the temperature-controlled radiofrequency therapeutic device, the application determines the corresponding temperature correction value according to the corresponding target fitting temperature model, and uses the temperature correction value as the heat lost in the process of indirectly collecting the skin temperature by the built-in temperature sensor through heat conduction, so that the temperature measured by the built-in temperature sensor in the temperature-controlled radiofrequency therapeutic device is closer to the skin temperature, thereby improving the accuracy of the measured temperature.
