The control module is used for presetting the heating value between two adjacent electrodes; the skin resistance of the range between the two adjacent electrodes detected by the skin electrical parameter detection module is received, the total power of the two adjacent electrodes is set according to the change condition of the resistance value so that the heat productivity between the two adjacent electrodes is constant, and the calculated total power is sent to the power driving circuit. The control module is also provided with a plurality of heating value gears, and the heating value between two adjacent electrodes is preset through the preset heating value gears.
Example two
As shown in fig. 2 to 4, corresponding to the first embodiment, the present embodiment provides a method for electrically stimulating skin, in which a plurality of electrodes are electrified to perform electrical stimulation, and the resistance of skin in a range between two adjacent electrodes is detected; the resistance of the skin in the range between every two adjacent electrodes is an independent resistance value; the resistance values are provided with a plurality of resistance values and are all recorded in the skin electrical parameter detection module; respectively adjusting the power of two adjacent electrodes; presetting the heating value between two adjacent electrodes; the skin resistance of the range between the two adjacent electrodes detected by the skin electrical parameter detection module is received, the total power of the two adjacent electrodes is calculated according to the change situation of the resistance value so that the heat productivity between the two adjacent electrodes is constant, and the calculated power parameter is sent to the power driving circuit.
As shown in fig. 2, the present embodiment will be described with reference to four electrodes as an example.
Before the device starts energy output, an initial value calibration is carried out on a stimulation area, the impedance between electrodes of each area part of each user is recorded and used as the reference of output energy and stimulation time, the heat obtained on unit impedance is the same for optimizing the effect of the stimulation area, the energy level V of stimulation is changed on a human-computer interaction interface, V is the equivalent level on the unit impedance in unit time, and the range is 1 to 10. Assume that the impedance between the customer's A site electrodes P1 and P2 is Z1-2Since the impedance values of the same part of different customers and the same part of the same customer are different, the reactance value measured according to the initial value is based on the V value and the measured impedance value Z in the system1-2And the power coefficient is adjusted to realize consistent output energy. That is, the energy actually output is Q1-2，Q1-2＝V*Z1-2And K is a fixed value and is related to the driving capability of a power module of the system. Suppose K is 200Since V ranges from 1 to 10; the time t in the actual stimulation process is set by the upper computer. Zone Z will follow each interval of stimulation1-2And the impedance is acquired and dynamically adjusted according to the actual detection result, so that the actually output energy can be dynamically adjusted, the stimulation is optimized, and the inconsistency of the stimulation effect is avoided. As follows: data Z measured from the first stimulus1-2V is set to 2, 400 Ω, Q of the actual output1-2＝V*Z1-2Where, when K is 200 and Z is 400, the maximum value of V is 10, so the maximum value of P is 20W; when the treatment is carried out with P-4W, after the stimulation is completed for 15min, the system adjusts the actual output power according to the magnitude of P, and the impedance of the part is measured to be Z after the stimulation is completedt(1-2)395, the stimulation result for the region is (400-; if a second stimulation is being performed Z1-2It becomes 395 Ω, and P790/K3.95W with the level V set unchanged. Therefore, even when the impedance of the skin in the same region is changed by adjusting P from 4W to 3.95W for the second time, the amount of heat generated from the electrode to the skin in the region is always constant by adjusting P.
As shown in fig. 4, when the system starts stimulation, electrical stimulation is firstly performed, and after the electrical stimulation is finished, magnetic stimulation is optionally performed to improve the activity and the tightening effect of the skin.
When independent electric stimulation is carried out without magnetic stimulation, the impedance between each pair of electrodes is different by n stimulation electrodes, so that the system has the impedance value of n (n-1)/2 channels, n is more than or equal to 2, taking 4 electrodes as an example, such as Z shown in a block diagram1-2、Z2-3、Z3-4、Z1-4、Z1-3、Z2-4As shown, assume the value Z actually measured by the initial sampling circuit1-2＝Z、Z2-3＝Z、Z3-4＝Z、Z4-1＝Z、Z4-2＝2Z、Z1-32Z, the energy obtained per unit impedance is V, and the energy output of the rf electrical stimulation of the corresponding channel is V Z, V Z, V Z, V Z, V2Z, V, respectively2Z; when the system sets radio frequency electrotherapy parameters and stimulates for t time, the sampling module can collect load impedance between corresponding stimulation universal electrodes in real time and automatically adjust a real-time energy output value, so that the optimization of the area stimulation effect is realized by continuous dynamic adjustment, the skin compactness is improved, and the skin activity is improved. When the system stimulation is finished, the system collects the static impedance after the stimulation of the stimulation area and records the static impedance in a client database.
EXAMPLE III
The embodiment provides a method for carrying out data quantitative evaluation on the electrical stimulation in combination with the second embodiment. After the skin in the area of the electrodes is stimulated according to the electrical stimulation method of example two. Assume that the impedance after stimulation is ZL1-2、ZL2-3、ZL3-4、ZL4-1、ZL1-3、ZL2-4Then the quantitative assessment of the stimulation effect on the stimulated zone is: (Z)1-2-ZL1-2)/Z1-2、(Z2-3-ZL2-3)/Z2-3、(Z3-4-ZL3-4)/Z3-4、(Z1-4-ZL4-1)/Z4-1、(Z1-3-ZL1-3)/Z1-3、(Z2-4-ZL2-4)/Z2-4The results indicate the degree of enhancement of skin activity on the basis of the original machine. The real-time effect after skin stimulation can be quantitatively obtained through the result, and the action of the system when the skin is stimulated is objectively reflected. As will be illustrated below, the following data are data after being stimulated for 30min between certain parts P1 and P2(P1 and P2 refer to electrodes) of a user of the stimulation system by using the electrode arrangement of FIG. 2. in order to improve the accuracy of the evaluation, the sampling values in the case of a plurality of excitation signals are given in the sampling module, respectively, the data in the case of 500kHZ, 250kHZ and 50kHZ, and the data in each frequency are averaged by sampling for a plurality of times, wherein the formula is Z500KHZThe number of the sampling points is (Z1+ Z2+. + Zm)/m, m represents the number of the actual sampling points, the value of m can be set by an upper computer, and the actual measured data are as follows:
| frequency (KHZ) | Impedance before stimulation (omega) | Impedance after stimulation (omega) | Evaluation results (%) |
| 50 | 265 | 255 | 3.77 |
| 250 | 240 | 230 | 4.1 |
| 500 | 225 | 215 | 4.4 |
The specific evaluation result is the final result according to the average value under the three frequency effects, and the effect evaluation value is
η＝(Z500KHZ+Z250KHZ+Z50KHZ) And/3 is 4.09%. Therefore, the actual skin effect between the electrodes P1 and P2 is improved by 4.09% on the original basis when the A patient stimulates. Therefore, the evaluation method provides the change data of the actual resistance value of the skin between the two electrodes after the skin is electrically stimulated, and the change data can be used as an evaluation standard to evaluate the effect of the skin after the skin is electrically stimulated; that is, the higher the evaluation value, the more effective the stimulationGood results are obtained.
The invention embodies a number of methods and approaches to this solution and the foregoing is only a preferred embodiment of the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be construed as the protection scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
