Description

User-customized lipolysis device using electrical stimulation {PERSONALIZED FAT REDUCTION DEVICE USING ELECTRICAL STIMULATION}

The present invention relates to a user-customized lipolysis device using electrical stimulation, and more particularly, to a user-customized fat fraction using electrical stimulation that measures a user's body information using near-infrared rays and feeds it back to decompose fat in the user's abdomen, etc. It's about the device.

Near-infrared rays are a kind of infrared rays located outside of red in the light spectrum, and are used for therapeutic purposes such as muscles and joints because they have a stronger thermal action than visible rays or ultraviolet rays.

These near-infrared rays have a large penetration depth that penetrates into the skin and are known to promote the activity of mitochondria in cells. Recently, NASA announced that near-infrared rays are effective in the treatment of skin diseases, brain tumors, cardiovascular diseases, cancer, and burns.

Near-infrared radiation uses low-power light that is harmless to the human body and is used for therapeutic purposes such as wound treatment, hair loss relief, skin wrinkle improvement, pain relief, fat reduction, etc. This is called photobiomodulation therapy.

Among the photobiomodulation treatment technologies, a device for dieting used to remove subcutaneous fat or visceral fat of the body by irradiating light in a wavelength band effective for fat decomposition is being developed.

However, in the case of a conventional device for decomposing fat by irradiating light, there is a problem in that different body characteristics or skin tones for each user cannot be considered by irradiating light having a uniform wavelength and output intensity.

Republic of Korea Patent Registration No. 10-1706850, filed by the present applicant as a related art, discloses an apparatus and method for measuring body fat, and describes an apparatus for measuring the thickness of subcutaneous fat using a light source in a near-infrared band.

In addition, Korean Patent Registration No. 10-1932071 filed by the present applicant discloses a metabolic monitoring-based body fat decomposition device, which receives light for body composition measurement, performs an analysis on the thickness and body composition of subcutaneous fat, and then displays metabolic monitoring information. A technology for generating and adjusting the intensity of each wavelength of a light source for body fat decomposition according to metabolic monitoring information is disclosed.

However, the above registered patents do not consider absorption or reflection of light according to the user's skin tone. For example, a dark skin tone user has a high light absorption rate, but a light skin tone user has a relatively low light absorption rate. This means that in the case of a user with a light skin tone, the effect to be achieved is low even if the light having the same output intensity is irradiated. In addition, it does not provide a mechanism for effective wavelength selection according to the physiological skin condition. For example, when the subcutaneous fat is thick, if a wavelength that increases the blood flow related to metabolism is selected, the effect is reduced or insignificant because the wavelength cannot penetrate deep into the body due to the thick subcutaneous fat, so it is solved based on physiological skin information A way to do this is required.

Assuming that the optical signal transmitted to the control unit 400 is divided into the first optical signal to the third optical signal according to the first to third positions of the body, the control unit 400 controls the body's first position, the second position, and Body information such as skin tone at the third location is calculated respectively. The control unit 400 controls the irradiator 500 arranged to be close to the measurement unit 300 according to a set calculation formula for the calculated body information, and the wavelength and output power of the second light irradiated from the irradiator 500 are each different from each other. can be different.

Shows how it has been improved. The above-described effect of the pipe lining of the present invention is more pronounced compared to the case of FIG. 11 (a) or (b), in which a delay time occurs as a stabilization time for chirping is required.

12 is an exemplary diagram illustrating a process of calculating an average value of an optical signal by applying a low-pass filter, and FIG. 13 is an average of an average value of an optical signal according to an embodiment of the present invention by dividing one cycle into a plurality of samplings. It is an example diagram showing the calculated result.

In one embodiment of the present invention, in order to calculate an average value from the waveform of the optical signal, the control unit 400 divides one period in the waveform of the optical signal into a plurality of samplings by replacing the low-pass filter, and An average value of the optical signal may be calculated by averaging the sampling sizes.

Referring to FIG. 12 , the waveform of the optical signal is an alternating or step-shaped waveform, and the average value is calculated to calculate body information. The step-shaped waveform may be obtained through filtering of a frequency band having the same phase as the frequency of the first light. This optical signal is converted to DC value using a low-pass filter or a high-pass filter to be read by the converter (ADC) of the micro controller unit, and then ADC is measured using The process of calculating the average value by passing it through a low-pass filter or a high-pass filter takes time to converge to the average value, which took about 1.5 seconds as a result of the experiment. .

In consideration of this, the control unit 400 of the present invention calculates an average value by dividing one period of the optical signal into a plurality of samplings, replacing the application of a low-pass filter for calculating an average value in a waveform formed by the optical signal. For example, as shown in FIG. 13 , the one cycle may be divided into eight samplings, and an average value of the optical signal may be calculated by averaging the magnitudes in the eight samplings.

The left side of FIG. 13 shows values according to eight samplings, and the right side shows values according to an oscilloscope. In the waveform of the optical signal, the average value of 8 samplings during one period is 2.16375, which is almost similar to the 2.1659 value of the oscilloscope. The number of sampling is shown as 8 in FIG. 13 of the present invention, but may vary depending on the wavelength, waveform, and the like of the optical signal.

The present invention to which the above method is applied can calculate the average value by measuring only one period (eg, 0.128 ms in the waveform of FIG. 9) compared to the method of calculating the average value by passing the low-pass filter, which is great for reducing the measurement time It has an effect and can calculate the average value with high precision when compared with the calculated value of the oscilloscope. This means the effect of real-time measurement and real-time body information calculation, and has the advantage of being able to immediately adjust the wavelength and output of the second light.
