[0075] The embodiment of the present application provides an electrothermal moxibustion head and a regulating system thereof, which can make the electric stimulation layer and the heating layer work together in the use process, can realize better drug permeability, is simple to operate and has good effect.

[0076] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiment in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0077] Please refer to Figure 1 , Figure 1 A flowchart of a regulating system of an electrothermal moxibustion head provided by the embodiment of the present application is provided. The regulating system of the electrothermal moxibustion head is applied to the electrothermal moxibustion head provided with an electric stimulation layer, a heating layer and a drug permeation layer. Specifically, the electrothermal moxibustion head in the embodiment of the present application can be a Bluetooth electrothermal moxibustion head, which integrates the electric stimulation layer and the heating layer and is provided with the drug permeation layer. The electric stimulation layer can be arranged below the heating layer, and the electric stimulation layer and the heating layer can be arranged in the shell of the electrothermal moxibustion head. The lower shell of the electrothermal moxibustion head can be provided with a groove for placing the mugwort, and the lower shell can be provided with the drug permeation layer. The drug permeation layer can adopt a microporous ceramic drug-loaded sheet, and active ingredients such as mugwort essential oil can be added, so as to improve the effect of drug properties in the use process.

[0078] Based on the electrothermal moxibustion head provided with the electric stimulation layer, the heating layer and the drug permeation layer, the power regulating system of the electrothermal moxibustion head in the use process can include the following steps.

[0079] The memory 1 is used for storing the computer program.

[0080] The processor 2 is used for executing the computer program to realize the following steps S110 to S130.

[0081] S110: Obtain the electrical parameter information of the current acupoint region;

[0082] It should be noted that in the process of using the electrothermal moxibustion head, the electrical parameter information of the current acupoint region corresponding to the electrothermal moxibustion head can be collected by the electrothermal moxibustion head. In actual application, the electrical parameter information of the current acupoint region can be obtained every interval of a preset time interval, wherein the electrical parameter information can include current real-time impedance Z_new and / or current real-time resistance R_real, and / or electromyographic signal and the like.

[0083] S120: Determine a new total power of the moxibustion head according to the electrical parameter information;

[0084] Specifically, in the embodiment of the present application, after obtaining the electrical parameter information of the current acupoint region, a new total power of the electrothermal moxibustion head corresponding to the electrothermal moxibustion head can be further determined according to the electrical parameter information.

[0085] S130: Control the working of the electrical stimulation layer and the heating layer according to the new total power of the moxibustion head.

[0086] It can be understood that after obtaining the new total power of the electrothermal moxibustion head, the power of the electrical stimulation layer and the heating layer of the electrothermal moxibustion head can be further regulated according to the new total power of the electrothermal moxibustion head, so as to guarantee the electrical stimulation effect of the electrical stimulation layer and the heating effect of the heating layer.

[0087] It should be noted that in the process of controlling the working of the electrical stimulation layer and the heating layer according to the new total power of the moxibustion head, a first output power can be obtained by combining the new total power of the moxibustion head based on a first proportion, and the heating layer is controlled to work based on the first output power; a second output power can be obtained by combining the new total power of the moxibustion head based on a second proportion, and the electrical stimulation layer is controlled to work based on the second output power.

[0088] For example, the first proportion is 60%~80%, and the second proportion is 20%~40%. That is, 60-80% of the new total power of the moxibustion head P_new is allocated to the heating layer, which is used to control the heating rate of the graphene film in the heating layer, so as to realize the effect of "warming meridians". 20-40% of the new total power of the moxibustion head P_new is converted into an electrical stimulation current, which is output through the silver fiber electrode of the electrical stimulation layer, so as to realize the synergy of "promoting blood circulation".

[0089] Therefore, the electrothermal moxibustion head in the application can obtain the electrical parameter information of the current acupoint area during use, determine a new total power of the moxibustion head according to the electrical parameter information, and then regulate the power of the electrical stimulation layer and the heating layer in the electrothermal moxibustion head according to the new total power of the moxibustion head, so as to control the electrical stimulation layer and the heating layer to work cooperatively. In addition, the electrothermal moxibustion head is provided with a drug permeation layer, which can achieve a better drug permeation effect during electrical stimulation and heating, and the operation is simple and the effect is good.

[0090] In one embodiment, the obtained electrical parameter information of the current acupoint area can include two data information of the current real-time impedance Z_new and the current real-time resistance R_real.

[0091] Therefore, the process of determining the new total power of the moxibustion head according to the electrical parameter information in S120 can include:

[0092] According to the current real-time impedance Z_new, the target resistance value R_target is calculated.

[0093] According to the target resistance value R_target and the current real-time resistance R_real, the new total power P_new of the moxibustion head is determined.

[0094] It can be understood that, in the process of obtaining the current real-time impedance Z_new and the current real-time resistance R_real in the application, the current acupoint area can be subjected to impedance scanning and resistance acquisition by the electrode matrix in the electrical stimulation layer to obtain the current real-time impedance Z_new and the current real-time resistance R_real. Specifically, the frequency of measuring the real-time impedance can be 50 kHz, that is, Z_new = measure_impedance(freq = 50kHz).

[0095] In the application, the Cole-Cole model can be used to calculate the target resistance value R_target according to the current real-time impedance Z_new, that is, R_target = calculate_target_R(Z_new). The target resistance value R_target reflects the electrical characteristics of the tissue in the best treatment state (such as when qi and blood are full and yin and yang are balanced).

[0096] After obtaining the target resistance value R_target, a new moxa head total power P_new can be further determined according to the target resistance value R_target and the current real-time resistance R_real. Specifically, a corresponding deviation resistance value can be obtained according to the target resistance value R_target and the current real-time resistance R_real, the deviation resistance value is analyzed by a fuzzy PID controller, and the current required moxa head total power P_new is calculated, that is, P_new = fuzzy_PID_controller(R_target, R_real), so as to realize the accurate regulation and control of "deficiency should be supplemented and excess should be purged".

[0097] It should be noted that the target resistance value R_target represents the ideal tissue resistance value calculated from the current real-time impedance Z_new, which represents the electrical parameter corresponding to the best intensity under the current blood state. The current real-time resistance value R_real represents the tissue resistance value (50 kHz frequency point) actually measured by the moxa head, which reflects the current real state. In actual application, in addition to distributing the new moxa head total power P_new according to different proportions to control the electric stimulation layer and the heating layer, the new moxa head total power P_new can also be used as the heating power set value output by the fuzzy PID controller to determine the moxa head heat production intensity, and then the electric stimulation intensity I_new = 0.2 * P_new is obtained according to the dynamic matching of the thermotherapy power, so as to realize the synergy of electric and thermal energy.

[0098] In an embodiment, the obtained electrical parameter information can include a current real-time impedance Z_new;

[0099] Therefore, the process of determining the new moxa head total output power P_new from the electrical parameter information in S120 can include:

[0100] Obtaining a measurement baseline impedance Z_baseline;

[0101] Determining a safety index ΔZ according to the current real-time impedance Z_new and the measurement baseline impedance Z_baseline;

[0102] Determining the new moxa head total power P_new according to the safety index ΔZ and the current moxa head total power P_old.

[0103] It can be understood that the current real-time impedance Z_new can be obtained in the present application, that is, the current acupoint region can be impedance scanned by the electrode matrix in the electric stimulation layer to obtain the current real-time impedance Z_new.

[0104] In practical applications, the safety index ΔZ can be determined according to the current real-time impedance Z_new and the measured baseline impedance Z_baseline. Specifically, in the process of determining the safety index ΔZ, the baseline impedance Z_baseline can be determined in advance. For example, when the electrothermal moxibustion head detects the start, a detection current of 0.1 mA and a frequency of 10 kHz is first applied, and the initial impedance is obtained through the electrode matrix of the electric stimulation layer. The initial impedance is the baseline impedance Z_baseline, so as to measure the baseline impedance Z_baseline.

[0105] Further, the safety index Δ_Z can be determined according to the current real-time impedance Z_new and the baseline impedance Z_baseline in the present application. The safety index Δ_Z corresponding to the current real-time impedance can be calculated by combining the safety index calculation relationship Δ_Z = abs((Z_new - Z_baseline) / Z_baseline) * 100. After obtaining the safety index Δ_Z, the safety index Δ_Z is combined with the current moxibustion head total power P_old to determine the new moxibustion head total power P_new. The physical meaning of the current real-time impedance Z_new, the measured baseline impedance Z_baseline and the safety index Δ_Z is shown in Table 1.

[0106] Table 1 Physical meaning of Z_new, Z_baseline and Δ_Z

[0107] Further, the above content of determining the new moxibustion head total power P_new according to the safety index combined with the current moxibustion head total power P_old can include:

[0108] In the case that the safety index Δ_Z is less than or equal to the first preset value, the current moxibustion head total power P_old is taken as the new moxibustion head total power P_new;

[0109] In the case that the safety index Δ_Z is greater than the first preset value and less than or equal to the second preset value, the new moxibustion head total power P_new is obtained based on the current moxibustion head total power P_old combined with the first power calculation relationship; the first power calculation relationship is a linear relationship;

[0110] In the case that the safety index Δ_Z is greater than the second preset value and less than or equal to the third preset value, the new moxibustion head total power P_new is obtained based on the current moxibustion head total power P_old combined with the second power calculation relationship; the second power calculation relationship is an exponential relationship;

[0111] In the case that the safety index Δ_Z is greater than the third preset value, the control of the moxibustion head is triggered to be powered off, and the new moxibustion head total power P_new is determined to be 0.

[0112] It should be noted that, please refer to Table 1, the safety index, namely the impedance change rate Δ_Z, is different in different ranges, the corresponding system response actions are different, and the biological basis is different. According to the current impedance change rate Δ_Z, the corresponding system response action can be determined from the impedance change rate Δ_Z and the system response action corresponding relationship table 2, and the new moxa head total power P_new can be determined according to the system response action.

[0113] For example, in the case that the safety index Δ_Z is less than or equal to the first preset value (such as 5%), the current moxa head total power P_old can be taken as the new moxa head total power P_new, that is, the current moxa head total power P_old is continued to be used for normal work. In the case that the safety index Δ_Z is greater than the first preset value (such as 5%) and less than or equal to the second preset value (such as 15%), the new moxa head total power P_new can be obtained according to the current moxa head total power P_old and the first power calculation relationship, wherein the first power calculation relationship is P_new=P_old*(1-0.03*ΔZ)]. That is, in the case that Δ_Z∈5%-15%, linear power reduction is performed, every 1% of the impedance change rate Δ_Z is reduced by 3% of the current moxa head total power P_old.

[0114] In the case that the safety index Δ_Z is greater than the second preset value (such as 15%) and less than or equal to the third preset value (such as 30%), the new moxa head total power P_new can be obtained according to the current moxa head total power P_old and the second power calculation relationship, wherein the second power calculation relationship is an exponential relationship P_new=P_old*e^(-0.05*ΔZ)]. That is, in the case that Δ_Z∈15%-30%, exponential power reduction (every 1% of the impedance change rate Δ_Z is reduced by 5% of the current moxa head total power P_old) is performed, and an audible and visual alarm can also be performed.

[0115] In the case that the safety index Δ_Z is greater than the third preset value (such as 30%), the control moxa head is triggered to be powered off, and the new moxa head total power P_new is determined to be 0. That is, the relay can be immediately triggered to be powered off, and the system preset time (for example, 10 minutes) can also be locked to improve safety.

[0116] Table 2: Impedance change rate Δ_Z and system response action corresponding relationship table

[0117] In an embodiment, the obtained electrical parameter information can only include the current real-time resistance R_real.

[0118] Therefore, the process of determining the new total power of the moxibustion head according to the electrical parameter information in S120 can include:

[0119] According to the current real-time resistance R_real, the reference resistance R_ref, the adjustment coefficient k, the preset power P_set, and the third power calculation relationship, a new moxibustion head power P_new is obtained.

[0120] The third power calculation relationship is:

[0121] P_new =P_set× [ 1- k×( {R_real - R_ref}÷R_ref)]-P_set, wherein P_set is a preset power, R_real is a current real-time resistance, R_ref is a reference resistance, k is an adjustment coefficient, and P_new is a new total power of the moxibustion head. P_set is an initial power set based on an embodiment, R_real represents a current measured tissue resistance, reflecting the water content or the contact state, the reference resistance R_ref represents a healthy tissue benchmark value, and the range of k can be 0.2-0.8. The specific value of k can be adaptively adjusted according to the type of tissue. -( {R_real - R_ref}÷R_ref) reflects the impedance deviation, that is, the rate of change of the tissue state.

[0122] It should be noted that the corresponding body mass index (BMI) can be determined according to the height and weight input by the user in advance, and the reference resistance R_ref can be determined according to the BIM. The relationship table of the reference resistance R_ref and the BIM is shown in Table 3.

[0123] Table 3 Relationship table of reference resistance R_ref and BIM

[0124] In actual application, a new moxibustion head power P_new can also be obtained according to the current real-time resistance R_real, the reference resistance R_ref, the adjustment coefficient k, the preset power P_set, and the third power calculation relationship P_new =P_set× [ 1- k×( {R_real - R_ref}÷R_ref)]-P_set. The new moxibustion head power P_new obtained by the method provided in the embodiment can make the power of the electric moxibustion head more suitable for the current physical condition of the user, which is beneficial to improve the use effect.

[0125] In an embodiment, the obtained electrical parameter information can include a current real-time resistance R_real.

[0126] Then, the process of determining the new total power of the moxibustion head according to the electrical parameter information in S120 can include:

[0127] According to the current real-time resistance R real and the target resistance R target, a current resistance deviation e is obtained t ; wherein e t =R_target-R_real.

[0128] According to the resistance deviation e t and the resistance deviation e t-1 of the last moment, a current deviation change rate Δe is obtained; that is, Δe=e t -e t-1 .

[0129] According to a pre-established correspondence relationship among the deviation type, the deviation change rate type and the power change amount, a power change amount ΔP corresponding to the current resistance deviation e t and the current deviation change rate Δe is determined.

[0130] The current total power P old of the moxibustion head is adjusted according to the power change amount ΔP, and a new total power P new of the moxibustion head is obtained.

[0131] It should be noted that the pre-established correspondence relationship among the deviation type, the deviation change rate type and the power change amount is shown in Table 4. After the current resistance deviation e t and the current deviation change rate Δe are obtained, the deviation type corresponding to the current resistance deviation e t may be further determined according to a correspondence relationship table between the resistance deviation and the deviation type (as shown in Table 5), and the deviation change rate type corresponding to the current deviation change rate Δe may be determined according to a correspondence relationship table between the deviation change rate and the deviation change rate type (as shown in Table 6). Then, the corresponding power change amount ΔPi can be further determined from the correspondence relationship table among the deviation type, the deviation change rate type and the power change amount shown in Table 4 in combination with the current resistance deviation e t and the current deviation change rate Δe, and then the total power change amount ΔP can be further obtained according to each ΔPi, and the new total power P new of the moxibustion head can be further obtained according to P new =P old + ΔP.

[0135] Table 6: Correspondence table of deviation change rate Δe and deviation change rate type

[0136] In the present application, according to each ΔP i , the process of obtaining the total power change amount ΔP can be realized by a defuzzification algorithm (i.e., the barycenter method): ; wherein, : the triggering strength (membership degree, range 0-1) of the ith fuzzy rule, indicating the matching strength of the current input (such as impedance deviation e, change rate Δe) to the fuzzy rule, the closer the value is to 1, the more applicable the rule is, and the closer the value is to 0, the more the rule is ignored. The calculation method is to take the minimum value of the condition membership degree for a multi-input system. -(ΔP i ) represents the fuzzy output value (such as the quantized value corresponding to the language variable “rapid increase” “moderate decrease” etc.) corresponding to the ith rule, which is the pre-set power adjustment suggestion (quantized value corresponding to the language variable) in the fuzzy rule library, and n represents the number of outputs. In the fuzzy control system, the simultaneous activation of multiple rules is a core design feature. Human body state changes are gradual processes rather than stepwise switching due to the continuity of physiological state. For example, when the impedance deviation changes from +10% to +15%, two rules are triggered simultaneously: rule A (positive), membership degree from 1.0 to 0.5; rule B (positive large), membership degree from 0 to 0.5, so the outputs of the two rules need to be integrated. For example, in the actual TCM diagnosis process, pulse, tongue coating, and inquiry information are considered simultaneously, each piece of information corresponds to a rule, and the final prescription is a weighted combination of these principles. Therefore, in the embodiments of the present application, impedance deviation, temperature change rate, and fatigue index are combined to calculate ΔP.

[0137] wherein i represents the rule number, and in Table 4, from positive large to negative middle, i starts from 1 and increases by 1 in turn.

[0138] In one embodiment, the obtained electrical parameter information can also include an electromyographic signal; when the system realizes the regulation of the electrothermal moxibustion head, it can also include:

[0139] adjusting the current intensity, output frequency, and output waveform of the electrical stimulation layer according to the electromyographic signal;

[0140] adjusting the temperature of the heating layer according to the electromyographic signal.

[0141] It should be noted that in the embodiments of the present application, the current intensity, output frequency and output waveform of the electric stimulation layer can also be adjusted according to the myoelectric signal, and the temperature of the heating layer can also be adjusted, so as to better adjust the power of the electrothermal moxibustion head according to the physiological signal of the user, so as to more accurately adapt to the actual needs of the user's body. Among them, the myoelectric signal can be obtained through the electric stimulation layer, including EMG signal amplitude / frequency change and the like.

[0142] Further, the process of adjusting the current intensity, output frequency and output waveform of the electric stimulation layer according to the myoelectric signal can include:

[0143] According to the myoelectric signal, the fatigue index and the muscle fatigue degree are determined;

[0144] According to the fatigue index, the basic current intensity of the electric stimulation layer and the current intensity relationship, the adjusted current intensity of the electric stimulation layer is determined;

[0145] According to the fatigue index, the corresponding relationship between the pre-established fatigue index range and the frequency is determined to determine the adjusted output frequency of the electric stimulation layer;

[0146] According to the current muscle fatigue degree, the corresponding relationship between the pre-established muscle fatigue degree and the output waveform of the electric stimulation layer is determined to determine the output waveform of the electric stimulation layer.

[0147] Specifically, please refer to the EMG signal characteristic change table as shown in Table 7. According to the amplitude and power peak value of the myoelectric signal (such as EMG signal), the muscle fatigue degree (i.e. which fatigue stage in Table 7) can be determined.

[0148] Table 7 EMG signal characteristic change table

[0149] It can be understood that in the embodiments of the present application, the corresponding fatigue index can be determined according to the myoelectric signal and the fatigue index calculation relationship. Among them, the fatigue index calculation relationship is:

[0150] Fatigue index=0.6×(EMGRMS÷baseline)+0.3×(fmedian÷100)+0.1×temperature slope.

[0151] Specifically, EMGRMS represents the root mean square of the myoelectric signal, reflecting the overall intensity of muscle electrical activity, baseline represents the average value of EMGRMS of the user in a resting state, fmedian represents the median frequency of the myoelectric signal power spectrum, and temperature slope represents the change rate of skin temperature per unit time. Among them, when the temperature is reduced (temperature slope<0), ΔP i =-5%, when the temperature is not reduced (temperature slope≥0), ΔP i =0%.

[0152] Specifically, in the embodiments of the present application, the current intensity of the electric stimulation layer after adjustment can be determined according to the fatigue index in combination with the basic current intensity of the electric stimulation layer and the current intensity relationship formula. The current intensity relationship formula is as follows: wherein, I new represents the adjusted output current intensity (unit: mA), I base represents the basic current intensity (preset according to the treatment scheme), k represents the safety adjustment coefficient (default 0.3, range 0.2~0.8), and the fatigue index represents the muscle state index calculated by multi-modal fusion (range 0~2).

[0153] In actual application, the adjustment amplitude corresponding to the fatigue index can be determined according to the fatigue index in combination with the corresponding relationship table of the fatigue index and the adjustment amplitude, and then the moxibustion head power is adjusted according to the adjustment amplitude on the basis of the current moxibustion head power. The corresponding relationship table of the fatigue index and the adjustment amplitude is shown in Table 8.

[0154] Table 8 Corresponding relationship table of fatigue index and adjustment amplitude

[0155] Specifically, in the embodiments of the present application, the output frequency of the electric stimulation layer after adjustment can be determined according to the fatigue index in combination with the corresponding relationship of the fatigue index range and the frequency which is established in advance. The corresponding relationship of the fatigue index range and the frequency is shown in Table 9.

[0156] Table 9 Corresponding relationship table of fatigue index range and frequency

[0157] That is, the muscle fatigue state and the corresponding stimulation frequency can be determined according to the fatigue index range. Specifically, when the fatigue index range > 0.7, the frequency is set to 20 Hz, the low frequency maintains the basic metabolism; when the fatigue index range is 0.4~0.7, the frequency is set to 50 Hz, the medium frequency promotes blood circulation; and when the fatigue index range ≤0.4, the frequency is set to 80 Hz, the high frequency enhances muscle strength.

[0158] Specifically, in the embodiments of the present application, the output waveform of the electric stimulation layer can be determined according to the current muscle fatigue degree in combination with the corresponding relationship of the muscle fatigue degree and the output waveform of the electric stimulation layer which is established in advance. The corresponding relationship of the muscle fatigue degree and the output waveform of the electric stimulation layer is shown in Table 10.

[0159] Table 10 Corresponding relationship of muscle fatigue degree and output waveform of electric stimulation layer

[0160] That is, after determining the muscle fatigue degree, the waveform output by the electric stimulation layer and the parameter information corresponding to the waveform can be determined according to the muscle fatigue degree in combination with Table 10, and the corresponding waveform can be output by the electric stimulation layer according to the waveform parameters, so as to achieve better electrothermal moxibustion effect.

[0161] In an embodiment, the process of adjusting the temperature of the heating layer according to the electromyographic signal can include:

[0162] The adjusted temperature of the heating layer is determined according to the fatigue index, the basic temperature, and the temperature-fatigue coupling coefficient.

[0163] It should be noted that in the embodiments of the present application, the adjusted temperature of the heating layer can be determined according to the fatigue index, the basic temperature, and the temperature-fatigue coupling coefficient in combination with a temperature calculation relationship, wherein the temperature calculation relationship is Ttarget=38+4×fatigue index, Ttarget represents the adjusted temperature of the heating layer, -38 represents the basic temperature value (equivalent to the core temperature of the human body +1°C), and -4 represents the temperature-fatigue coupling coefficient (which is a clinical experience value). It can be understood that the electrothermal synergistic function of the moxibustion head in the embodiments of the present application can make the penetration depth of the medicinal effect reach 8-10 mm, which is 3 times of the traditional moxibustion, and the matching error of the temperature and the electric stimulation parameters is small, which can usually be less than 3%, and the functional consistency is improved by 90%.

[0164] In an embodiment, before acquiring the electric parameter information of the current acupoint area in S110, the system can further include the following steps when implementing the regulation of the electrothermal moxibustion head:

[0165] Acquiring the current contact state of the moxibustion head;

[0166] In the case that the contact state is normal, the step of acquiring the electric parameter information of the current acupoint area is performed.

[0167] It should be noted that in the embodiments of the present application, the current contact state between the moxibustion head and the skin can be determined first, and if the contact state is normal, the electric parameter information of the current acupoint area can be acquired and the power of the moxibustion head can be adjusted.

[0168] Specifically, the current real-time alternating current impedance of the skin (accuracy ±5Ω) can be measured by the electrode array, and the contact state between the moxibustion head and the skin can be determined in real time; or the attachment pressure of the moxibustion head can be detected by a pressure sensor, such as a flexible piezoresistive sensor (range 0.1-2N / cm²), and the contact state can be determined by the pressure value, wherein detecting the attachment pressure of the moxibustion head by the pressure sensor is conducive to ensuring the stability of the heat conduction efficiency.

[0169] For example, after detecting the current real-time impedance, the impedance fluctuation range and the impedance change trend are determined. If the impedance fluctuation range is between ±5Ω, it means that the baseline is stable, and the moxa head is in normal contact with the skin. If the impedance rises by >15Ω, it means that the moxa head and the skin have partially detached, and the contact state is poor. If the current real-time impedance→∞, it means that the open circuit state, and the contact state is that the moxa head is completely detached.

[0170] The code for determining the contact state by real-time alternating current impedance is as follows: def check_contact_status(impedance, pressure): if impedance >baseline + 15 or pressure < 0.3: return "POOR_CONTACT" elif impedance > 1e6:# impedance out of range return "DETACHED" else: return "GOOD_CONTACT".

[0171] The contact state can be determined according to the pressure value, as shown in Table 11.

[0172] Table 11 Relationship table of pressure value and contact state

[0173] When the contact state is "GOOD_CONTACT", the current acupoint area electrical parameter information can be obtained, and the new moxa head total power P_new can be determined according to the above S120 corresponding specific implementation mode, so as to better adjust the moxa head total power, so as to achieve better effect. In one embodiment, when the system realizes the regulation and control of the electrothermal moxa head, it further comprises:

[0174] In the case of poor contact, the new moxa head total power is obtained by reducing the current moxa head total power by a preset percentage (e.g. 0.3);

[0175] In the case of excessive compression, the moxa head is powered off, and the new moxa head total power P_new is determined to be 0.

[0176] It can be understood that when the disconnection state is "POOR_CONTACT", P new=0.3*P old, that is, when the contact is poor, the power is reduced to 30% of the preset power, so as to avoid local overheating caused by poor contact, thereby reducing the risk but maintaining certain functions, and of course the user can also be reminded to check the contact through sound and light and the like; when the contact state is "DETACHED", P new=0, that is, when completely detached, the power is reduced to zero, that is, the output is stopped, and the system can also be locked for a period of time (such as 300 seconds) and an alarm is issued to prevent the device from working in the case of not contacting the skin and causing accidents.

[0177] In an embodiment, when the system implements the regulation of the electrothermal moxibustion head, it can further include:

[0178] According to the working mode selected by the user, the working parameters of the moxibustion head are determined;

[0179] According to the working parameters, the moxibustion head works.

[0180] It should be noted that in order to facilitate the user to use, the electrothermal moxibustion head in the embodiment of the application can also be pre-set with multiple working modes, and the user can select the corresponding working mode through the function option, and the electrothermal moxibustion head system determines the corresponding working parameters according to the working mode selected by the user, and controls the moxibustion head to work according to the working parameters.

[0181] It can be understood that in the case of the working mode being the pain relief mode, the working parameters include the output power of the electric stimulation layer and the temperature of the heating layer; for example, TENS electric stimulation (80Hz) + constant temperature 48℃.

[0182] In the case of the working mode being the cold and damp dispelling mode, the working parameters include the intermittent heating parameters and the low-frequency massage electric pulse frequency; for example, intermittent heating (50℃±5℃ fluctuation) + low-frequency massage electric pulse (10Hz).

[0183] In the case of the working mode being the drug moxibustion cooperation mode, the working parameters include the intermediate frequency electric stimulation frequency of the electric stimulation layer. For example, the intermediate frequency electric stimulation is 4kHz to drive the drug ion to penetrate.

[0241] It should be noted that the regulating device of the electric heating moxibustion head provided in the embodiments of the present application has the same beneficial effects as the regulating system of the electric heating moxibustion head provided in the above embodiments, and for the specific introduction of the regulating system of the electric heating moxibustion head involved in the embodiments of the present application, please refer to the above embodiments, which will not be described here again.

[0242] On the basis of the above embodiments, another aspect of the present application provides an electric heating moxibustion head comprising the regulating system of the electric heating moxibustion head as described above and an upper shell, an outer insulation layer, a heating layer, an electric stimulation layer, a lower shell, a drug permeation layer and a contact layer distributed from top to bottom in sequence.

[0243] It should be noted that please refer to the structure explosion diagram of the electric heating moxibustion head shown in Figure 4 , and the structure diagram of the electric heating moxibustion head shown in Figure 5 and Figure 6The overall joint diagram of the electrothermal moxibustion head is shown. The outer insulating layer in the present application can adopt medical-grade polycarbonate (temperature resistance 200℃), and a Bluetooth antenna (gain 3dBi) can be integrated in the outer insulating layer to ensure that wireless communication is not interfered by electrothermal interference; the electric stimulation layer can adopt a flexible ring-shaped electrode array, such as silver fiber weaving, with impedance <0.1Ω / cm², and the electric stimulation layer can support low-frequency (1-100Hz) and medium-frequency (1-10kHz) modulation; the heating layer can adopt a graphene film heating sheet (heating rate ≥5℃ / s) with a built-in 16-point temperature sensor; the drug permeation layer can adopt a microporous ceramic drug-loaded sheet (pore size 10-50μm) that can load active ingredients such as wormwood essential oil; the contact layer can adopt biocompatible silicone, and the surface of the contact layer has a design of convex points (height 0.5-2mm) to enhance the acupoint pressing effect, for example, a mechanical sensitive ion channel can be excited by a pressure of 0.5N / cm² to produce a "qi" feeling (sour, numb, swelling, and heavy).

[0244] Specifically, the electrothermal moxibustion head in the embodiments of the present application can be a Bluetooth electrothermal moxibustion head, which can specifically adopt a Bluetooth 5.3 chip (supporting MESH networking) to manage communication and user instructions, and the processor can monitor the current information (precision ±0.1mA) collected by the electric stimulation layer and the temperature fluctuation (±0.3℃) of the heating layer in real time. The memory and the processor in the embodiments of the present application can be arranged in the upper shell.

[0245] The electrothermal moxibustion head in the embodiments of the present application can adopt a double-isolation design to ensure electromagnetic compatibility, which can specifically satisfy electrical safety isolation and electromagnetic compatibility isolation when adopting the double-isolation design.

[0246] First, the physical isolation design (also known as structural-level protection) includes:

[0247] The interlayer insulation architecture includes an aluminum oxide insulating layer and a shielding isolation cavity, which can specifically adopt an aluminum oxide insulating layer, that is, an aluminum oxide ceramic layer (voltage resistance ≥4kV, volume resistivity ≥ Ω·cm) with a thickness of 0.2mm is arranged between the electric stimulation electrode (high-voltage side) and the heating module (low-voltage side) to block the direct current leakage current path. The shielding isolation cavity can specifically adopt a separate cavity structure design, in which the high-frequency control circuit (Bluetooth / WiFi module) and the analog signal circuit (bioelectricity detection) are respectively packaged in independent titanium alloy shielding covers (shielding effectiveness ≥60dB@1GHz).

[0248] Specifically, the safety distance control includes a creepage distance and a PCB layout, wherein the creepage distance is that a minimum air gap of a high-voltage circuit (such as an electric stimulation module) and a touchable component is greater than or equal to 4 mm, and an along-face distance is greater than or equal to 8 mm (to meet a double insulation requirement). The PCB layout is that a digital signal line and an analog signal line are orthogonal and are routed at a distance greater than or equal to 3 times a line width to reduce crosstalk (the crosstalk is actually measured to be reduced to less than or equal to -90 dB).

[0249] Second, frequency isolation design (signal level protection) includes:

[0250] Frequency division multiplexing technology, that is, an electric stimulation signal: a 1-100 Hz low-frequency pulse (bandwidth ≤ 200 Hz) is used; biological impedance detection: a 50 kHz-1 MHz high-frequency carrier (no overlap with the electric stimulation spectrum) is used; Bluetooth communication: a 2.4 GHz frequency band is used, and a band-pass filter (suppression ratio ≥ 40 dB) is used to limit out-of-band radiation.

[0251] Modulation and demodulation strategy, including: orthogonal frequency division multiplexing (OFDM): control signals and bioelectric signals are distributed to different subcarriers to ensure spectral isolation; spread spectrum technology: a Bluetooth signal uses FHSS (frequency hopping spread spectrum) to reduce single-frequency radiation power (to meet YY0505 radiation emission limit value).

[0252] Third, grounding and filtering design (circuit level protection) includes:

[0253] Double grounding system, such as protective earth (PE): a metal shell is connected to the ground through a low-impedance path (≤0.1 Ω) to discharge leakage current; signal ground (SGND): a star single-point grounding topology is used to avoid ground loop interference (common mode noise suppression ratio ≥ 80 dB).

[0254] Filter network design, such as power input end: a π-type filter (differential mode insertion loss ≥ 40 dB @ 150 kHz-30 MHz) is inserted; signal interface: a common mode choke coil (impedance ≥ 1 kΩ @ 100 MHz) is used in cooperation with a TVS diode (response time ≤ 1 ns).

[0255] The electrothermal moxibustion head in the embodiment of the application can measure skin impedance by using a multi-frequency current excitation (such as 1 kHz-1 MHz) during use, and construct an impedance spectrum (Nyquist diagram or Bode diagram).

[0256] Among them, the equivalent circuit fitting can adopt Cole-Cole model (R1-(R2 / (1+(jωτ)^α))) to fit the impedance data, and extract the characteristic parameters (R0, R∞, tau, α). The impedance amplitude of a specific frequency band (such as the low frequency region reflecting intercellular fluid and the high frequency region reflecting cell membrane characteristics) can be calculated to extract the frequency spectrum characteristics. The original impedance signal can be obtained by the four-electrode method (2 excitation electrodes+2 measurement electrodes), and the measurement frequency points include 10kHz, 50kHz, 100kHz, 1MHz. If the 10Hz amplitude ↑5%, it indicates that the tissue is dehydrated (10 times more sensitive than temperature), and if the 100kHz phase mutation, it indicates that the electrode contact is poor (response time <50ms).

[0257] In order to ensure the effect, the heating can be started first (warming up to 45℃ within 3 seconds) in the initial stage of using the electrothermal moxibustion head, the skin pores are opened, and then the electric stimulation (frequency 20Hz) is applied after a delay of 0.5 seconds to promote drug penetration. The electrothermal moxibustion head in the application uses the muscle tremor effect of electric stimulation to enhance the heat conduction efficiency, increases the temperature at the subcutaneous 2cm place by 30%, realizes energy coupling, and adopts a three-level protection system to improve the use safety, which includes a hardware level: overcurrent fuse (fusing threshold 500mA) and temperature fuse (critical value 70℃); a software level: abnormal pattern recognition based on ML (such as electrode falling off, local overheating); a biological feedback level: triggering emergency stop through impedance mutation detection (change rate >15%).
