Description

Description Ultrasonic slimming equipment Technical field

The present invention relates to an ultrasonic slimming device for locally slimming a whole body or a region to be thinned using ultrasonic waves.

Background art

As a slimming device, a device using various physical stimuli such as ultrasonic waves, low-frequency electricity, high-frequency, pressure, and heat has been conventionally provided. (See Patent Documents 1 to 3). Due to the characteristics of ultrasound, it is known that the lower the frequency, the more energy reaches the deeper part of the body, and the higher the frequency, the higher the energy consumption rate in the shallow part of the body and the less the effect on the deep part of the body. I have. It has also been clarified that cavitation effects on living tissues can be adversely affected if the frequency is low. For this reason, in order for ultrasonic waves to act on a living body, it is natural that the effect and safety must be carefully considered.However, conventional slimming devices require that ultrasonic irradiation conditions be adjusted based on scientific evidence. What has been decided may include irradiation conditions that are difficult and that easily cause cavitation. Also, if the frequency is low, the ultrasonic energy can reach deep into the body and increase the temperature of the bones and internal organs inside the body when used continuously, and there is still room for improvement.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In order to remove excess fat from the body, you first need to break down the fat, It is necessary to burn lunar fat.

Lipolysis is performed by secreting catecholamines. Catecholamine is a collective term for three substances, dopamine, noradrenaline, and adrenaline, and secretes catecholamines from sympathetic nerve endings and adrenal glands by stimulating the sympathetic nerves in the body's particularly lean areas with ultrasound. And promote this secretion. Incidentally, the six average of the results of human monitoring experiment as shown in FIG. 4, the irradiation power 0.1 at a frequency 1 MHz to a site desired to瘦5 ~ 0. 8 W / cm 2 of that the catecholamine to ultrasonic irradiation (noradrenaline ) Has been confirmed to be secreted. In addition, as for the burning of fat, if UCP 3 of the Uncoupling Protein (UCP) in the fat layer and muscle layer is specifically activated by ultrasonic stimulation, the decomposed fat is burned. I know it will be easier.

Here, the sympathetic nerve endings exist in the deep part of the skin (dermis layer), and the depth from the skin surface is about 1 to 2 mm. The fat and muscle layers are at a depth of about 2 to 3 cm from the skin surface.For example, irradiating ultrasonic waves with a frequency around 1 MHz can reach a depth of about 5 cm to reduce the slimming effect. That's enough to get. However, considering the effects on internal organs and the like, it is preferable to control the irradiation power on the skin surface to keep the irradiation dose on internal organs and the like low and ensure safety. When the frequency is low, the influence of cavitation may be considered, so it is preferable to control the irradiation power low, but it is thought that the slimming effect is reduced. In other words, to obtain a slimming effect safely and efficiently without affecting the internal organs, etc., the frequency of the ultrasonic waves must be 1.3 MHz or more.

Here, Table 1 shows the difference in the half-value layer depending on the frequency for each living tissue, and Tables 2 and 3 show that the ultrasound power of lWZcm ² and 0.8 WZ cm ² The decay of the irradiation power when irradiating the surface is calculated based on the half-value layer in Table 1, respectively.

(table 1)

Frequency 1 MHz 3 MHz

Each organization

Skin 4.O cm 1.6 cm Fat 4.9 cm 1.9 cm

Muscle 2.3 cm 0.7 cm

(Table 2)

(Table 3)

As can be seen from Tables 1 to 3, the irradiation power at the time of reaching the internal organs and the like deeper than the muscles becomes smaller as the frequency becomes higher if the irradiation power at the time of irradiation is the same. In addition, it can be seen that if the frequency is constant, the larger the irradiation power at the time of irradiation, the larger the irradiation power. Ultrasonic irradiation conditions, such as frequency and irradiation power, are not only set to a frequency of 1.3 MHz or more as described above, but also affect the sympathetic nerve and uncoupled protein family in consideration of the half-value layer. It must be determined within a range that stimulates the body and does not affect the internal organs deep in the body. Specifically, in consideration of the effect of ultrasonic waves on internal organs and the like, when the frequency is in the range of 1.3 to 3 MHz, the irradiation power is set to 0.5 to ³ W / cm ² . When the frequency is in the range of 1.3 to 3 MHz, the irradiation power should be in the range of 0.5 to ³ WZcm2 in consideration of the effect of supersonic waves on internal organs, etc. , Frequency 3 When it exceeds MH z, for the purpose of illuminating a relatively shallow portion in essentially the body as described later, the irradiation power so as to set to 0.0 5 to 0. Of 5 WZ cm ² range You may.

In this way, by irradiating ultrasound to a body part to be lean and activating the conjugated protein family present in the skeletal muscle at the irradiated part, a high local slimming effect can be obtained. In this case, ultrasound can be applied to the lower scapula, axilla, back neck, etc., where brown fat cells that control heat production in the whole body are present, so that a high overall slimming effect can be obtained.

In addition, “heat production” means to produce (produce) heat in the body. If the heat production power is high, energy consumption is large, so fat does not accumulate and it does not become fat. Conversely, low energy consumption leads to fat accumulation and fatness. Heat production also acts to maintain body temperature homeostasis.

Next, the present invention will be described with reference to examples.

(Example 1)

As shown in FIG. 1, an ultrasonic slimming device 1 including an ultrasonic generator 3 having an ultrasonic vibrator 2 and a controller 4 for controlling the ultrasonic vibrator 2 is used. Then, ultrasonic waves are irradiated while the ultrasonic wave generating section 3 is in contact with the surface of the desired portion 6 where the user wants to lose weight. Here, it is preferable to apply a jewel 7 as an ultrasonic transmission medium between the ultrasonic generator 3 and the desired site 6. This jewel 7 is similar to that used in ordinary ultrasound diagnosis, for example, hydrophilic one in which water is retained in lipoxyl methyl cellulose, and caffeine is contained in the inside. A substance that promotes lipolysis, such as capsaicin, or a substance that can provide a slimming effect may be included.

Thus, the ultrasonic waves emitted from the ultrasonic generator 3 of the ultrasonic slimming device 1 pass through the jewel 7, stimulate the sensory organs in the skin at the desired site 6, and enhance the sympathetic nerve. As a result, catecholamines are secreted to cause lipolysis. Furthermore, the ultrasound reaches the fat layer and the muscle layer, and activates the uncoupled protein family (heat-producing protein) in the fat layer and the muscle layer by the stimulation of the ultrasound, and as a result, breaks down the decomposed fat. High efficiency slimming effect can be obtained by burning efficiently Things.

In addition, instead of using the ultrasonic generator 3 for partial slimming as described above, the ultrasonic generator 3 is applied to the surface of a desired part for slimming the whole body such as the lower scapula, axilla, and back neck where brown fat cells are present. By irradiating the ultrasonic waves, the brown fat cells can be enhanced to increase the heat productivity of the whole body, that is, the ultrasonic slimming device 1 can be used for slimming the whole body.

Here, the control unit 4 irradiates the ultrasonic waves in the mode set by the user with the switch 4a. The ultrasonic slimming device 1 is used to reduce fat inside the body and muscles, and to reduce fat located relatively shallower (near the epidermis). Mode can be switched by switch 4a. When set to “Deep mode”, the frequency is selected in the range of 1.3 to 3 MHz, and the irradiation power is selected in the range of 0.5 W / cm ² or more and 3 W / cm ² or less. The control unit 4 controls the ultrasonic vibrator 2 so that a sound wave is emitted. When the mode is set to “shallow mode”, the frequency is selected in the range of 3 to 15 MHz, and the irradiation power is in the range of 0.05 WZ cm ² or more and less than 0.5 W / cm ² . The control unit 4 controls the ultrasonic vibrator 2 so that the ultrasonic wave selected in the step is irradiated.

(Example 2)

As shown in FIG. 2, an ultrasonic generator 13a having an ultrasonic oscillator 12a, an ultrasonic generator 13b having an ultrasonic oscillator 12b, and each ultrasonic oscillator 1 Using an ultrasonic slimming device 11 having a control unit 14 for controlling 3a and 13b, one ultrasonic generating unit 13a is applied to the surface of a desired part 6 of the body 5 which is desired to be thin. In addition, the other ultrasonic generator 13b is applied to the surface of the desired part 16 for whole body slimming, such as the lower scapula, axillary part, and back neck, where the brown luster cells are located, and the ultrasonic wave is applied. Is irradiated. Here, between the ultrasonic generator 13a and the desired part 6, and between the ultrasonic generator 13b and the desired part 16, a jewel 7 similar to that shown in the first embodiment is provided. Applying power S Preferred.

Thus, the ultrasonic waves emitted from the ultrasonic generator 13a of the ultrasonic slimming device 11 pass through the jewel 7, and stimulate the sensory organs in the skin at the desired site 6 to enhance the sympathetic nerve. As a result, catecholamines are secreted to cause lipolysis. Further, the ultrasound reaches the fat layer and the muscle layer, and the uncoupled protein family in the fat layer and the muscle layer is activated by the stimulation of the ultrasound, and as a result, the decomposed fat is efficiently burned. Thus, a high slimming effect can be obtained locally. In addition, the ultrasonic waves emitted from the ultrasonic wave generating section 13b pass through the jewel 7, and enhance brown fat cells existing at the desired site 16 to thereby increase the heat productivity of the whole body. In other words, the ultrasonic apparatus 11 of the present embodiment can perform both partial slimming and whole body slimming at the same time, but both ultrasonic generators 13a and 13b can be used for whole body slimming. Yes, it can be used for partial slimming of different parts. Furthermore, it is also possible to further provide the same ultrasonic wave generating sections 13a and 13b so as to perform slimming of a plurality of parts simultaneously with slimming of the whole body.

Here, the control unit 14 emits ultrasonic waves in a mode set by the user via the switch 14a. Ultrasound slimming device 1 is a “deep mode” for reducing fat inside the body and muscles, and a fat for relatively shallower portions (near the epidermis). “Shallow mode” can be switched by switch 14a. When set to "deep mode", the frequency is selected in the range of 1.. 3 to 3 MHz, the irradiation power ultrasonic selected is irradiated with 0. 5W / cm ² or more 3W / ^/ cm ² or less in the range The control unit 14 controls the ultrasonic vibrator 12 as described above. Moreover, when set to "shallow mode", the frequency is selected in the range of 3 to 1 5 MHz, the irradiation power is at 0. 0 5W / _C m ² or more 0. 5 W / cm ² less than the range The control unit 14 controls the ultrasonic vibrator 12 so that the selected ultrasonic wave is emitted.

Note that instead of selecting the mode with the switch 14a, for example, the vibrator 12a is used for the "deep mode" and the vibrator 12b is used for the "shallow mode" so that it can be used selectively during use. You may do it.

(Example 3)

As shown in FIG. 3, an ultrasonic irradiation unit 25 including an ultrasonic generator 23 having an ultrasonic vibrator 22 and a control unit 24 for controlling the ultrasonic vibrator 22 detects a distance to internal organs and bones. and a sensor unit 26 and the detection unit 28 to the detection result to the control unit 24 and a control unit _{2 7} for which full Eid back of the sensor unit 26 which, using the ultrasonic slimming device 2 1, comprising, in the body 5 Ultrasonic irradiation on the surface of the desired part 6 where you want to lose weight Ultrasonic waves are emitted while the ultrasonic generating section 23 of the section 25 and the sensor section 26 of the detecting section 28 are in contact with each other. The detection unit 28 of the present embodiment detects the distance to the internal organs and bones by using the difference in the reflectivity of ultrasonic waves depending on the substance. Here, it is preferable to apply the same jewel 7 as that shown in Embodiment 1 between the ultrasonic wave generating part 23 and the desired part 6.

Then, the distance from the skin surface of the desired part 6 of the body 5 to the skin and bone is detected by the sensor part 26 of the detection part 28 of the ultrasonic slimming device 21 and the detection result is controlled by the control part 27. To the control unit 24 of the ultrasonic irradiation unit 25. The correlation between the distance to the internal organs and bones and the safe and efficient ultrasonic output and frequency (regression equation) is input to the control unit 27 in advance, and the appropriate frequency and irradiation corresponding to the results of the detection unit 28 Irradiate the ultrasonic wave to the ultrasonic wave irradiating section 25 in a single step. Correlation between ultrasonic power and frequency

(Regression formula) The data is determined based on the concept of the half-value layer and the ultrasonic energy. For example, if the distance from the skin surface to the internal organ is detected as 3 to 5 cm, the data is set in advance and the data is determined. Control is performed to reduce the irradiation power by half.

The ultrasonic waves emitted from the ultrasonic wave generator 23 in the ultrasonic wave irradiator 25

It passes through 7 and stimulates the sensory organs in the skin at the desired site 6 to enhance the sympathetic nerve, and as a result secretes catecholamine to cause lipolysis. Further, the ultrasonic waves reach the fat layer and the muscle layer, activate the uncoupled protein family in the fat layer and the muscle layer by ultrasonic stimulation, and as a result, efficiently burn the decomposed fat. Thus, a high slimming effect can be obtained locally.

Here, the irradiation conditions of the ultrasonic wave can be selected according to the mode selected by the switch 24a, and when the frequency is 1.3 to 3 MHz, the irradiation power is 0.5 W / cm ² or more. 3 W cm ² while following ultrasonic selected in the range is irradiated, when the frequency is 3 to 1 5 MH z, irradiation power is 0. 0 5 W / cm ² or more 0. 5 WZ cm ² less than The irradiation condition is selected based on the results of the detection unit 28 so that the irradiation conditions are determined so that the ultrasonic waves do not affect the internal organs and bones. And safety has been assured.

Furthermore, if the distance to the internal organs and bones is determined to be smaller than the specified value, the control to reduce the irradiation power further than specified or to stop the ultrasonic irradiation is detected. It may be performed in part 28. That is, when it is determined that the distance from the skin surface to the internal organs and bones is 0.5 to 2 cm, the detection unit 28 narrows the irradiation path further than specified, and the distance from the skin surface to the internal organs and bones is 0. If it is determined that the distance is less than 5 cm, the detection unit 28 can also perform control for stopping irradiation of the ultrasonic wave.

Also, instead of using the ultrasonic generator 23 of the ultrasonic slimming device 21 for partial slimming as described above, it is desirable to use for the whole body slimming such as the lower scapula, axilla, and back neck where brown fat cells are present. By irradiating ultrasonic waves in a state where the ultrasonic waves are applied to the surface of the site, brown fat cells can be enhanced to increase the heat productivity of the whole body, that is, the ultrasonic slimming device 21 can be used for slimming the whole body. In addition, a plurality of ultrasonic generators 23 and detectors 28 are provided, respectively, to simultaneously perform partial slimming of multiple parts, simultaneously irradiate ultrasonic waves to multiple desired parts for slimming whole body, It is also possible to perform slimming and one or more partial slimming at the same time.
