Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
As shown in fig. 1, the present embodiment provides a dynamic quadrupole radio frequency control device, including a microcontroller, a radio frequency generator and a signal acquisition module, where the radio frequency generator is electrically connected to radio frequency electrodes through a radio frequency amplification circuit, the number of the radio frequency electrodes is an integral multiple of 4, and every four radio frequency electrodes form a radio frequency matrix to electrically stimulate skin at the radio frequency matrix;
the radio frequency generator is used for generating radio frequency signals required by physical therapy, the radio frequency amplification circuit is used for amplifying the received radio frequency signals to required radio frequency energy and outputting the radio frequency energy to the radio frequency electrode, and the radio frequency electrode is used for being in contact with the skin of a human body so as to enable the human body to receive the radio frequency energy emitted by the radio frequency control device;
the signal acquisition module is used for acquiring skin signals in contact with a user and feeding the monitored skin signals back to the microcontroller, and the microcontroller is used for processing the received skin signals and controlling the radio-frequency electrode to switch the energy transmission state. The skin signals collected by the signal collecting module comprise skin temperature signals and skin impedance signals.
The four dynamic states of the radio frequency matrix can be schematically represented by fig. 2, 3, 4 and 5; wherein 1, 2, 3 and 4 are all shown as electrodes, and 5, 6 and 7 are current paths; in this embodiment, the RF energy is RF, which is alternating current and the corresponding positive and negative electrodes are periodically exchanged. The dynamic quadrupole refers to four antipode combination states. Specifically, as shown in fig. 2, in the first half period, the first rf electrode 1 is positive, the second rf electrode 2, the third rf electrode 3, and the fourth rf electrode 4 are negative, and in the second half period, 1 is negative, and 2, 3, and 4 are positive. The antipodes generate ac currents 5, 6, 7, respectively. Here, the current 7 is the target current of the present embodiment.
More preferably, the number of the radio frequency electrodes is 4; the four electrode heads form a square radio frequency matrix, and the current generated by the diagonal corners of the square is the target current. The radio-frequency electrodes comprise a first radio-frequency electrode 1, a second radio-frequency electrode 2, a third radio-frequency electrode 3 and a fourth radio-frequency electrode 4, the energy transmission states are four, and as shown in fig. 2, when the electrode state of the first radio-frequency electrode 1 is different from the electrode state of the second radio-frequency electrode 2, the electrode state of the third radio-frequency electrode 3 and the electrode state of the fourth radio-frequency electrode 4, the first radio-frequency electrode is in a first state; as shown in fig. 3, when the electrode state of the second rf electrode 2 is different from the electrode state of the first rf electrode 1, the third rf electrode 3 and the fourth rf electrode 4, the second rf electrode is in the second state; as shown in fig. 4, when the electrode state of the third rf electrode 3 is different from that of the first rf electrode 1, the second rf electrode 2 and the fourth rf electrode 4, the third rf electrode is in a third state; as shown in FIG. 5, the fourth RF electrode 4 is in the same electrode state as the first RF electrode 1, the second RF electrode 2 and the third RF electrode 3. Fig. 2 shows a state 1 of the dynamic quadrupole, in which 1, 2, 3, 4 are four electrodes, and 5, 6, 7 are paths of co-channel current in the state. The currents 5, 6 generate magnetic fields which act on the 7, so that the current of the 7 acts more deeply, and the depth can reach d, namely twice the depth of the dipolar radio frequency 2/d. In a period, 5, 6 and 7 currents respectively generate corresponding magnetic fields, the magnetic fields and the currents interact with each other pairwise, specifically, the target current is used as an analysis object, and the current 7 is acted by the magnetic field generated by the current 6 and the magnetic field generated by the current 5. The further the current is from the opposite distance, the less the magnetic field force.
More preferably, an impedance matching circuit is further disposed between the radio frequency amplifying circuit and the radio frequency electrode, and the impedance matching circuit is used for enabling the generated radio frequency energy to reach a load point more uniformly.
When the signal acquisition module acquires the sudden increase of the impedance (electrical stimulation reaction) acting on the skin, the state 1 is converted into the state 2, so that the target position can receive the radio frequency energy more efficiently. Similarly, the state is circularly converted from 1-2-3-4. Impedance detection and impedance matching constant power control enable the skin to receive RF energy more uniformly and accurately. When the sudden increase of the impedance is detected, the electric stimulation response is judged, and the state is switched. After the state switching, the paths of the current 7 are different and opposite, so that the skin on the current path in the original state does not bear the current any more, and the burden of the skin is reduced.
The Dynamic Quadrupole Radio Frequency (DQRF) control technology can deepen the action depth of the RF, can dynamically transform electrodes according to skin impedance, changes a current path, reduces the burden of non-target skin, and can greatly improve the effect. The dynamic quadrupole control technology aims at the problems of heavy burden and unobvious depth of non-target skin in a current path and low efficiency caused by skin electric stress reaction caused by electrode fixation of the existing skin management equipment, and can realize deeper radio frequency energy, more comfortable action and higher efficiency.
Example two
As shown in fig. 6 and 7, the present embodiment provides a dynamic quadrupole radio frequency control method, including the following steps:
firstly, setting corresponding radio frequency time and power, namely receiving physiotherapy time and physiotherapy power set by a user; for example, the therapy time may be set to 10 minutes, and the power may be set to the power required by the user to be treated.
S0: detecting whether the radio-frequency electrode is in contact with the skin, if so, outputting radio-frequency energy, and if not, continuing to detect; this step is mainly to detect whether there is skin contact, and if there is no skin contact, the radio frequency energy is not continuously output, so that on one hand, it can reduce the energy loss, and on the other hand, it can avoid the problem of impedance detection.
S1: when the sudden increase of the impedance acting on the skin is detected, executing step S2;
s2: and controlling a radio frequency matrix formed by the radio frequency electrodes to be switched into different energy transmission states so as to enable the radio frequency energy transmission to be more uniform. That is, when a sudden increase in impedance is detected, it is determined that the electrical stimulation is responding, and the state is switched. After the state switching, the paths of the current 7 are different, and the skin does not bear the current on the original state current path, so that the burden is reduced.
Specifically, the skin temperature and impedance detection in the control process enable the skin state to be monitored more accurately, the impedance matching and DQRF control enable the RF energy to reach the target position more accurately, and the RF energy is enabled to be more efficient while the burden of non-target skin is reduced.
As shown in fig. 2, fig. 3, fig. 4 and fig. 5, when the signal acquisition module acquires a sudden increase of the impedance acting on the skin (i.e. an electrical stimulation reaction occurs), the rf electrode is controlled to switch from state 1 to state 2, so that the target location receives the rf energy more efficiently. Similarly, the state is circularly converted from 1-2-3-4. Impedance detection and impedance matching constant power control enable the skin to receive RF energy more uniformly and accurately.
