The RF beauty device of multichannel temperature controlTechnical field
The present invention relates to a kind of human body beauty treatment device, particularly a kind of devices that human body beauty treatment is carried out using radio-frequency technique.
Background technique
As living standard improves in recent years, people increasingly pay attention to itself appearance, various beauty apparatusInto the visual field of people, helps people's maintenance and improve the appearance of oneself, these beauty apparatus are all much to utilize light, electricity, soundEtc. physical effects cope with the various problems of skin or human body.
Wherein RF beauty technology is the barrier that epidermal basal melanocyte is penetrated using rf wave, makes skin corium collagenFiber-heated to such as 55 DEG C -75 DEG C of certain temperature, collagenous fibres are shunk, and are tightened up loose wrinkle of skin, while fuel factorMake Collagen Proliferation, newborn collagen rearranges, and quantity increases, and the impaired collagen layer of aging is repaired, to reach smoothing wrinkle FirmEffect.
This technology is performed for more than the treatment skin side that normal physiological body temperature heating is a kind of prevalence to subcutisMethod is modified using non-damaging gangrenosum acne temperature activated and repairs the natural physiology course of skin appearance, and reduces subcutaneous fat, suitablyTemperature heating not will lead to hemoglutination, but fibroblast can be stimulated to synthesize collagen, and may change the new old of fat cellMetabolism, is conducive to lipolysis.
The typical reaction that tissue increases reaction to temperature is as follows, and 37-44 DEG C: accelerating metabolism and other natural mistakesJourney；44-45 DEG C: the conformation change of protein, including collagen；The cell death of warm；60~70 DEG C: protein denaturation；The solidification of collagen, film, hemoglobin；The contraction of collagenous fibres；90~100 DEG C: extracellular vacuolization；Liquid evaporation；>100DEG C: thermal ablation；Carbonization.
In RF therapy and beauty, need to be maintained at certain temperature range for the temperature of treated tissue, temperatureIt spends low, is not achieved treatment optimum efficiency, temperature is excessively high to damage skin or treated tissue damage.
RF therapy is segmented into two types again, and one is intrusive radio frequency, RF energy directly passes through such as micropin electricityPole is pierced into the tissue that need to be treated and imports, another is non-intruding radio frequency, radio-frequency electrode and dermal contact, and RF energy passes through tableSkin, which is coupled to subcutaneous tissue, is treated.
The advantages of non-intrusion type radio frequency be it is more convenient safer, on Working Life influence it is smaller, but RF energy pass throughCan also skin temperature be allowed to increase when epidermis, the excessively high epidermis of temperature can generate the side effects such as pain, redness, bubble, although in the presence ofIndividual difference can generally generate pain when skin temperature is more than 43 DEG C.
From the above it can be seen that for RF therapy especially non-intrusion type radio frequency, to treated tissue/region/tableSkin carries out monitoring temperature, and changes RF energy or other treatment parameter according to the result of monitoring temperature, to can ensure that radio frequencyTreatment achievees the effect that.

To achieve the above object, the present invention adopts the following technical scheme that.
RF beauty device includes power module, radio-frequency module, treatment head, control module etc.；Wherein electric power source pair of module is penetratedFrequency module, control module, treatment head etc. are powered, and control module controls entire RF beauty device work according to user instructionsMake, radio-frequency module is used to generate power radio-frequency power signal, and treatment head is contacted with skin treatment area, and is existed by treatment headMovement on skin expands the treatment region of skin, in broad scope hereof, for skin treating and for the table of beautifying skinIt is identical to state meaning, temperature control be temperature controlled abbreviation, electrode and radio-frequency electrode and radio-frequency power coupling electrode unless stated otherwiseOtherwise meaning is identical.
The power module can may include mentioning by rechargeable battery or by AC Adapter AC adapter by batteryThe DC power supply of confession is constituted；Radio-frequency module is made of radio-frequency signal generator and radio-frequency power amplifier, generates power radio-frequency letterNumber.The watt level that the module generates radio frequency can be controlled by main control module.
This paper treatment head is defined as the component in RF beauty device with treated direct skin contact, and treatment head includes to penetrateFrequency electrode, what needs to be explained here is that treatment head of the invention can be moved directly on treated skin over the course for the treatment of, areaIt is substantially secured to a certain position in those other therapeutic process, such as the therapeutic equipment of mask type, difference can be repeatedly fixed on by being also different fromThe difference of the therapeutic equipment of position, such as the therapeutic equipment of waistband type, the therapeutic equipment of the present invention position different from being repeatedly fixed on existsIn time in treatment of the invention, it spatially can be continuously, it is continuous in time to refer to that apparatus of the present invention treat skin regionRf power signal can persistently be output to treatment biological tissue when domain switches, and spatially continuously refer to that treatment head of the present invention is being controlledIt can persistently be slided on treated skin without departing from treated skin, apparatus of the present invention and mask type and waistband type during treatmentAnother difference of therapeutic equipment be that waistband type or mask type therapeutic equipment may carry out fixation for treatment device dependent on frenulumIn position in need for the treatment of, and apparatus of the present invention are that apparatus of the present invention contact skin can be dependent on manually as being continuously appliedCertain pressure is fixed to contact skin without frenulum；It is to be noted that use of the invention, which is not repelled, is fixed on certainOne position, does not repel space over the course for the treatment of yet or the time is upper discontinuous.
Treatment head includes at least two or more metals or conductive electrode and penetrates as with curer's skin contactFrequency power coupling electrode, the power coupling electrode are connected with RF power module simultaneously；Treatment head simultaneously also comprising two orMultiple temperature sensors are used to measure the temperature of patient skin.
The form for the treatment of head can be individual handle, and a RF beauty device host can have multiple handles at this time；Treatment head and RF beauty device host are also possible to integrated, and treatment head can be located at the one of RF beauty device host at this timeEnd, treatment head can be made replaceable, also can be made non-exchange.
It can be monopolar radio frequency that treatment head, which exports radio frequency method, or bipolar radio frequency or multi-pole rf include a littleBattle array radio frequency, for electrode arrangements mode also there is no limit, generally, for monopolar radio frequency, skin treatment area is mainPositioned at electrode and skin contact region, for its treatment region of bipolar radio frequency in addition to electrode and skin contact region further include electrodeBetween skin area, multi-pole rf itself is the mutation or extension of bipolar radio frequency, its treatment region is similar with bipolar radio frequency.

The corresponding treatment region of the electrode for the treatment of head is divided according to temperature sensor number, each temperature sensorPosition or each temperature sensor measurement position and the region after division center correspond；For the ease of retouchingIt states, lower face handle skin all areas in need for the treatment of are known as whole treatment region, and sometime treatment head radio-frequency electrode can be controlledThe skin area treated is known as electrode therapy region, bipolar radio frequency or multi-pole rf electrode it is adjacent between treatment region callSubregion is treated, for bipolar radio frequency mode, two electrodes constitute an electrode pair, for the electrode to its skin treating sub-districtDomain is usually located between two electrodes, if the number of temperature sensor is identical as electrode logarithm, temperature sensor places electrodeTo between, it is placed on electrode pair or treatment subregion center or leans on paracentral position, so that temperature sensor measurementMaximum temperature limit reflects the electrode to the therapeutic state of skin, for that can share some between bipolar radio frequency Different electrodes pairElectrode does not influence the position of temperature sensor；For multi-pole rf, multi-pole rf essence is also bipolar radio frequency, when between electrodeWhen treating subregion number more than temperature sensor number, such as lattice radio frequency, there are many lesser treatments under normal circumstancesRegion, it is assumed that there are N number of temperature sensors, and it is close adjacent lesser treatment subregion can be combined to form N number of sizeCombined therapy region, then each combined therapy regional center position place temperature sensor, or place temperature sensorIt is allowed to measured zone and is located at combined therapy regional center position.
Be mapped by overhead temperature sensor and radio-frequency electrode and treatment subregion or therapeutic combination region, i.e., someSpecific temperature sensor corresponds to a piece of specific skin treatment area, which corresponds to one or more radio frequencies againElectrode, for ease of description, the one or more radio-frequency electrode are known as the correspondence radio-frequency electrode group of the temperature sensor；General feelingsThe corresponding one or more radio-frequency electrodes of a temperature sensor are considered under condition, naturally it is also possible to consider that multiple temperature sensors are correspondingOne or more radio-frequency electrodes, only this mode implementation complexity is big and relatively subtle with respect to the former improvement below.
Each temperature sensor ceaselessly measures temperature during RF therapy, and by each temperature feedback to control template,Control module adjusts the radio frequency parameter that radio-frequency module is input to each corresponding radio-frequency electrode group, radio frequency parameter packet according to temperature valueIt includes and is not limited to radio-frequency power, RF phse, rf frequency etc.；It is a kind of that optionally simply way is when some temperature sensor measurementTo temperature reach or when beyond target temperature, be shut off the radio-frequency power output of the corresponding radio-frequency electrode group of the sensor；WhenMore complicated temperature control algorithm can also be so used, such as on above-mentioned temperature control logical foundations, if some measured temperatureMore than one higher temperature threshold values then close all radio-frequency power outputs, and temperature controlled logic can be each treatment regionIt is independent to combine consideration.
A kind of way of extension is less than temperature sensor number and controls when radio-frequency electrode and its treatment region are groupedWhen treating subregion or areal is treated in combination, it can virtually exceed the temperature sensor of actual number, at this moment there is certain controlTreating regional center position may be without the situation of actual temperature sensor, and the temperature in the region, can pass through other regions at this timeMeasured temperature interpolation obtain.
A kind of implemented method of radio-frequency treatment head is that treatment head includes the strip radio-frequency electrode that several are parallel to each other, phaseAdjacent radio-frequency electrode constitutes a radio-frequency electrode pair, and each radio-frequency electrode places a temperature sensor, this realization to centreIt includes three strip radio-frequency electrodes being parallel to each other that fairly simple way, which is treatment head, in method, these three radio-frequency electrodes are constitutedTwo radio-frequency electrodes pair, that intermediate electrode are the common electrode of two electrodes pair, and two temperature sensors are located at twoFor radio-frequency electrode to the center in the region of composition, Fig. 4 to Figure 12 gives some possible implementation methods for the treatment of head, including adoptsWith the modes such as strip radio-frequency electrode mode, circular RF electrode and loop-type radio frequency electrode, lattice radio frequency electrode, but the present invention is completeBe not limited to these implementation methods, the intension of the invention combined in radio-frequency electrode with temperature sensor be different radio frequency electrode orElectrode grouping and corresponding temperature sensor constitute multiple temperature control channels or make treated region multiple subregions can it is independent orPart independent temperature.
