BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fat removal patch having an ultrasound radiation function,

The present invention relates to a fat removal patch, and more particularly, to a fat removal patch having an ultrasonic radiation function that induces removal of adipocytes by irradiating ultrasonic waves to the skin by attaching the patch to a desired body part in different shapes and sizes.

In general, intense exercise or labor, sudden muscle use, or severe stress can cause pain such as muscle aches, arthralgia, fracture, back pain, shoulder pain, and the like. Such pain is usually treated through physical therapies such as massage, massage, and acupressure, or magnetic therapy with magnets. Physiotherapy is practiced by a physical therapist who practices massage, massage, acupressure, etc.

Typical examples of physiotherapy equipment include expensive massage machines that use solenoids or vibration motors as a driving force for vibratory stimulation, and low-frequency treatment machines that generate muscular signals to generate muscular signals. On the other hand, the magnetic therapy therapy is distributed as a magnetic pace class which is treated by improving the blood circulation by attaching a magnet having a magnetic force of a predetermined intensity to the acupoint, under the trade name "Papi self room ". Magnets having a magnetic force of 700 Gauss, 1,200 Gauss or the like are used for such conventional magnetic flaws.

However, in the case of the conventional treatment method as described above, first, in the case of the liposuction machine and the physical therapy using the high frequency, the space for the treatment is required and the time and the cost are excessively required, And secondly, in the case of the magnetic therapy therapy represented by the magnetic pace flow, there is a problem that the therapeutic effect is slow due to the improvement of the blood circulation by the magnetic force, and the effect is limited.

Korean Patent Registration No. 10-1041769, which is one of the related arts, discloses a 'pressure sensitive adhesive pad for radiating electromagnetic waves' in which power is supplied from a battery to a frequency oscillator and an LED so that a frequency oscillator generates a frequency and sends the frequency to a film- Discloses a technique that emits ultrasonic waves toward the facial part of the facial region to relax the muscles of the facial region to remove wrinkles and remove fat from a part of the body using another frequency.

FIG. 1 is a schematic view for explaining a main function of a pressure-sensitive adhesive pad for radiating electromagnetic waves according to the related art.

As shown in FIG. 1, the adhesive pad 100 for radiating electromagnetic waves in the electromagnetic wave radiation pad 20 has a frequency range of 20 KHz to 20 MHz, which relaxes the muscles of the body, It is to spread out.

The adhesive pad 100 is formed on a lower portion of a nutrient pad 10 made of a flexible material adhered to the skin of the face such as a facial face and attached with medicinal materials or nutrients to penetrate through the skin, An electromagnetic wave radiation pad 20 for relaxing the muscles of the body and spreading the wrinkles is attached to the upper part of the body.

A film type antenna 21 for radiating electromagnetic waves is formed between the nutrition pad 10 and the electromagnetic wave radiation pad 20 and a frequency oscillator 22 is connected to the film type antenna 21 to oscillate the frequency. A battery socket 30 capable of coupling a cylindrical battery 31 for supplying power to the film antenna 21 is attached to the sides of the nutrition pad 10 and the electromagnetic wave radiation pad 20.

At this time, the cylindrical battery 31 is inserted into the battery socket 30 and supplies power to the frequency oscillator 22 and the LED 40. That is, the cylindrical battery 31 is inserted into the battery socket 30 to be supplied with electric power while being in contact with the electrodes of the frequency oscillator 22 and the LED 40, and the frequency oscillator 22 can supply a frequency at which muscle relaxation is possible Shaped antenna 21 connected to the frequency oscillator 22, as shown in FIG.

As a result, the electromagnetic waves that can relax the muscles are radiated to the facial face through the adhesive pad 100 containing the medicinal material and the nutrients, thereby relaxing the muscles of the facial face so that the wrinkles are removed more quickly and the convenience is enhanced The lifetime of the cylindrical battery 31 is indicated by the LED 40 to the user.

Here, the frequency determination can be performed by selecting a desired frequency oscillator 22 and determining a frequency band that is most effective for muscle relaxation between 20 kHz and 20 MHz. An upper pad 50 using a film type battery 51 for supplying power to the film type antenna 21 may be attached to the upper portion of the electromagnetic wave radiation pad 20, And is attached to the bottom surface of the upper pad 50 to be connected to the frequency oscillator 22 and the LED 40 to supply power.

However, as described above, since the conventional pad must implement an electronic circuit including an antenna on a considerably thin pad, it is very difficult to manufacture a product and the stability in use can not be secured. In addition, since the conventional pad can not change the amount of electromagnetic waves radiated from the pad according to the user, variable control is required according to the age of the user, the state of the user's skin, and the like.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Like reference numerals refer to like elements throughout.

2 is a plan view of a fat removal patch having an ultrasonic wave radiation function according to the present invention.

2, the fat removing patch 200 having an ultrasonic wave emitting function according to the present invention includes an outer layer 301, a control unit 210 and a battery 511, which are provided in the outer layer 301, An inner layer 307 facing the outer layer 301 and a circuit layer 305 provided between the outer layer 301 and the inner layer 307 to generate ultrasonic waves.

3 is a plan view of an outer layer of a fat removal patch having an ultrasound radiation function according to the present invention.

The outer layer 301 is an outer layer of the fat removal patch according to the present embodiment, which is an outer layer 301 of a rectangular silicon material with reference to a plan view as shown in FIG. Of course, the present invention is not limited thereto, and the outer layer 301 may be circular, oval, and polygonal based on a plan view. In addition, the material may be a silicon material or a material having properties similar to silicon. A battery 511 is provided in the outer layer 301 and a controller 210 is provided to be exposed to the outside.

The battery 511 can be installed in a non-replaceable state or can be provided with a cover on the outer layer 301 so that the battery 511 inside the cover can be replaced. Such a battery 511 is preferably a lithium battery 511, but a coin battery 511 may be used, and a rechargeable secondary lithium battery 511 may be used if necessary. Here, when the battery 511 is the secondary lithium battery 511, it may include a separate charging device or an internal charging circuit. Meanwhile, when the battery 511 is embedded in the outer layer 301 in a non-replaceable manner, a coil is embedded in a material such as permalloy in the outer layer 301, and the coil is connected to the battery 511 to be charged wirelessly It is possible. Of course, in this case, the outer layer 301 should be provided with a coil connected to an external power source such as a wireless charger, for example, permalloy.

The control device 210 is for controlling ultrasound emission, and includes a control button for this purpose. Here, the control button includes a power button for turning on / off the system power, an output control button for varying the output level of the ultrasonic wave, and a mode control button for controlling the operation pattern of the ultrasonic wave on a mode-by-mode basis. In addition, the power button, the output control button, and the mode control button included in the control device 210 are exposed to the outside of the outer layer 301 so that the user can operate the device. For example, A cover is provided on the surface of the outer layer 301 and the power button, the output control button, and the mode control button are exposed through the three openings.

The operation pattern of the ultrasonic wave that can be selected from the mode control buttons includes a first mode in which all the antennas 401 are operated in a lump to emit the ultrasonic waves to a fixed output throughout the desired body part, A second mode in which a plurality of antennas 401 are activated to selectively emit ultrasonic waves to a desired part of a body part, a plurality of antennas 401, And a fourth mode in which ultrasonic waves are partially and sequentially outputted to all desired body parts.

Meanwhile, a switching terminal 311 may be provided between the control button and a circuit layer 305 to be described later. The switching terminal 311 is for energizing the wiring formed in the circuit layer 305 when the control button is pressed. The present embodiment exemplifies the switching terminal 311 formed of conductive rubber. In addition, a switching pattern is formed in the circuit layer 305 so that switching is performed by the switching terminal 311, and the switching terminal 311 is located on the switching pattern. Here, the switching pattern is a disconnected wiring, and the disconnected wiring can be energized by the switching terminal 311. [ That is, the switching terminal 311 has a thin thickness, and the region provided with the control button protrudes upward. When the control button is pressed, the upward protruding region is downwardly pressed and brought into contact with the switching pattern. As a result, the switching pattern, which is the disconnected wiring, is energized by the switching terminal 311 pressed downward. Of course, the downwardly-urged switching terminal 311 is turned into a shape protruding upward when the external pressing factor disappears.

The inner layer 307 accommodates the circuit layer 305 to be described below together with the outer layer 301 in a shape corresponding to the outer layer 301. This inner layer 307 illustrates a flexible plastic epoxy material having a different shape than the outer layer 301. Of course, the shape and material of the inner layer 307 may be changed in the same manner as the outer layer 301.

The present invention may further include a bonding layer 308 under the inner layer 307 to directly contact the skin of the user so that the ultrasonic waves can reach the fat layer well.

Since ultrasound is a sound wave, it needs a medium to propagate unlike light, and the delivery speed varies depending on the characteristics of the medium. The ultrasound beam is transmitted through the bone, fat, muscle, and skin of the human body. The intensity of the beam, that is, the propagation velocity, is reduced because absorption, reflection, and scattering occur during the passage through the medium to be. The inner layer 307 is composed of an insulator made of a flexible plastic epoxy that blocks the ultrasonic waves from leaking out so that an ultrasonic wave of an intended intensity can be transmitted to the fat layer when the antenna 401 transmits ultrasonic waves.

Also, the inner layer 307 is brought into contact with the skin. It is very important to match the acoustic impedance of the inner layer 307 with the acoustic impedance of the skin. The reason is that the larger the impedance difference between the two media, the greater the reflectivity. The electrical resistance of the skin varies widely depending on age, sex, and water content of the human body, but is generally about 2.5 kΩ. Therefore, the bonding layer 308, which is a portion of the inner layer 307, which is in contact with the skin, uses a skin adhesive which is harmless to the skin. In order to perform impedance matching at the time of manufacturing, a material having an impedance value of about 2.5 k? .

4 is a plan view of a fat removal patch circuit layer having an ultrasonic wave radiation function according to the present invention.

4, the circuit layer 305 includes an antenna 401 and a control circuit 403 for transmitting a control signal when the ultrasonic wave is radiated to the antenna 401 do.

The antenna 401 is for radiating ultrasonic waves, and may include at least one antenna 401. The at least one antenna 401 may be formed of three or more antennas 401 and the antenna 401 may be formed of a group of five antennas 401. Here, each antenna 401 group can be individually driven or collectively driven by the control circuit 403. [ Also, in this embodiment, the antenna 401 is patterned on flexible paper, and one end of each antenna 401 is connected in parallel, and the other end of each antenna 401 is connected to the control circuit 403.

5 is a block diagram of a fat removal patch having an ultrasound radiation function according to the present invention.

The control circuit 403 is for driving the antenna 401 and drives at least one antenna 401 sequentially or collectively. The control circuit 403 uses a flexible circuit board. Therefore, the flexibility of the outer layer 301 and the inner layer 307 is not affected, and the ease of use is not deteriorated. The control circuit 403 is mounted on a flexible circuit board for driving the antenna 401 and controls the ultrasonic output by a programmed algorithm. The control circuit 403 includes the MCM oil 501 and a distributor 527, an output circuit 520 and a rating circuit 515 as shown in Fig.

In response to the switching operation of the mode switch 503 for setting and controlling the ultrasonic wave radiation pattern or the amount of output, the MC fluid 501 supplies a voltage control signal for outputting a set frequency signal for ultrasonic wave generation, And provides a control signal for radiating ultrasonic waves to the antenna 401 by activating the program. It is needless to say that the MCU 501 may use an 8-bit microcomputer or a 16-bit microcomputer depending on the program, and may use ATMEGA8, ATMEAG128, or other one-chip microcomputers. The MCU 501 is equipped with an oscillator 505, which is not illustrated, and an oscillation frequency is set according to the type of the MCU.

The distributor 527 selectively controls switching of at least one antenna 401 based on the radiation control signal.

The output circuit 520 supplies the set frequency signal to the distributor 527 in response to the voltage control signal. The output circuit 520 includes a voltage controlled oscillator (VCO) 521 for converting the voltage supplied from the rating circuit 515 into a set frequency signal in accordance with the voltage control signal, a voltage controlled oscillator A power amplifier 523 for amplifying the output voltage to a predetermined level, and an attenuator 525 for adjusting the output level of the power amplifier 523. [

The voltage-controlled oscillator 521 receives a voltage control signal provided from the MCM 501. Here, the level of the DC signal, that is, the signal magnitude, is set by the MCM 501 as the DC control signal. Therefore, the voltage-controlled oscillator 521 outputs a frequency proportional to the signal level of the voltage control signal, and in order to effectively remove the fat cells, a plurality of frequency outputs are most efficiently performed in the range of 20 kHz to 30 MHz.

The frequency can be continuously varied within the range of 20 kHz to 30 MHz without fixedly controlling the set frequency band. This is because ultrasonic waves are used to induce vibration of cell tissues. When a fixed frequency signal is provided, there is a limitation in removal of adipocytes because the cell tissue induces only fixed vibrations. Therefore, in the present invention, the frequency signal is continuously transmitted in the range of 20 kHz to 30 MHz so as to transmit ultrasonic waves, thereby irregular vibration is generated without inducing regular vibration in the cell tissue, thereby maximizing necrosis of cells. That is, the present invention transmits ultrasound in a linearly variable frequency band to efficiently necrotize adipocytes. For example, it is possible to vary the frequency signal at intervals of 1 minute within the band of 20 kHz to 30 MHz, and it can be repeatedly increased by 1 kHz from 20 kHz to 30 kHz and then decreased by 11 kHz. However, the present invention is not limited to this, and it is also possible to repeat the pattern in which the frequency is increased from 20 kHz to 30 kHz, but is increased by 2 kHz and then decreased by 1 kHz. That is, after increasing from the initial 20 kHz to 22 kHz, it may be decreased to 21 kHz after a predetermined time, for example, 1 minute, and then increased to 23 kHz after one minute. Thereafter, the pattern is again reduced to 22 kHz, and after one minute, the pattern increased to 24 kHz is repeatedly increased to 30 kHz. After reaching 30 kHz, it is possible to repeat the pattern for 1 kHz increase after decreasing 2 kHz every predetermined time, for example, 1 minute. This is reduced to 30 kHz, to 28 kHz, then to 1 kHz, to 29 kHz, again to 1 kHz, to 27 kHz repeatedly to 20 kHz. Thereafter, the above-described process can be repeated again.

The rating circuit 515 supplies the rated power to the output circuit 520 and the MCM 501. To this end, the rated circuit 515 receives the power from the battery 511 installed in the control device 210 and converts it into the rated power. The power supply of the battery 511 can be minimized by supplying power to the rated circuit 515 based on the operation of a separate power switch. A separate light source 531 can be connected to visually display the operating state of the system. This can be implemented, for example, by lighting green when the system is operating normally and turning on red when an error occurs.

The operation of the fat removing patch having the ultrasonic wave emitting function according to the present invention having the above-described structure is as follows.

First, the user attaches a fat removal patch to a desired site, and then uses the control device 210 to start the system operation. That is, the control device 210 receives the system operation start input from the user and causes the system to operate.

When the system is operated, the power supplied from the battery 511 is supplied to the rating circuit 515 by the power switch 513. The rating circuit 515 regulates the power of the battery 511 to a rated power, for example, 3.3V, for supplying the circuit of the system. The voltage output from the rating circuit 515 is supplied to the MCU 501 and the output circuit 520, and the MCU 501 initiates system operation through initialization of the system.

When the MCU 501 is initialized, the MCU 501 recognizes the switching operation of the mode switch 503, and the operation for each mode is selected according to the operation of the mode switch 503. [ Here, the operation mode is divided into the first to third modes, as described above.

When the first mode is selected, the MCM 501 outputs the emission control signal to the distributor 527, and sets all of the plurality of antennas 401 connected to the distributor 527 to be enabled. This allows all the antennas 401 to be supplied with a frequency signal for ultrasonic emission, and the distributor 527 allows the frequency signals to be transmitted to the respective antennas 401 in parallel by the non-contact switching circuit. The frequency signal is obtained by supplying the voltage control signal to the output circuit 520 of the MCM 501. The voltage control signal is not a voltage for setting a specific frequency but a frequency signal for ultrasonic emission It is a signal to be linearly variable. Accordingly, the MCY 501 linearly changes the voltage level for frequency setting and supplies the output voltage to the output circuit 520. [

The voltage-controlled oscillator 521 of the output circuit 520 generates a frequency signal based on the output voltage of the rated circuit 515 in accordance with the voltage control signal, and converts it into a signal of a predetermined level through the power amplifier 523 And then provided to the distributor 527 via the attenuator 525. [ Accordingly, the ultrasonic waves are emitted from the plurality of antennas 401 provided in the circuit layer 305, and the user obtains the fat removing effect.

When the second mode is selected from the mode switch 503, the MCY 501 induces the user to select the ultrasonic emission position. The user selects an arbitrary position, up, down, left, and right using the mode switch 503.

The MCU 501 recognizes an arbitrary position selected from the mode switch 503 and then controls the distributor 527 so that the antenna 401 corresponding to the selected position is selected. Since the distributor 527 includes a decoder circuit, when a code corresponding to an arbitrary position is input, the antenna 401 at that position is selected.

For example, when the decoder included in the distributor 527 is a 3x8 decoder, up to eight positions can be selected. Thus, according to the second mode operation of the mode switch 503, The fat removal site is controlled to be specifically selected and operated.

Meanwhile, when the third mode is selected from the mode switch 503, the MCM 501 provides the corresponding emission control signal to the distributor 527. Here, the radiation control signal sequentially enables a plurality of antennas 401 connected to the distributor 527 as a control pattern corresponding to the second mode. In addition, the frequency divider 527 receives frequency signals from the output circuit 520, and ultimately, frequency signals for radiating ultrasound are sequentially supplied to the respective antennas 401 through the distributor 527.

Also, when the fourth mode is selected from the mode switch 503, the MCM 501 provides the spin control signal corresponding to the fourth mode to the distributor 527. [ The distributor 527 sequentially enables a plurality of antennas 401 connected to the distributor 527. The distributor 527 distributes a plurality of antennas 401 according to a frequency signal provided from the output circuit 520, And sequentially provides frequency signals for radiating ultrasonic waves to some of the antennas.

For example, after the upper end antenna 401 of the boats provided in the circuit layer 305 is operated for a predetermined time, the lower end antenna 401 of the boats is operated for a predetermined time, and then the left and right antennas 401) can be continuously repeated. If necessary, the start of the antenna 401 can be superimposed at the switching time for starting each antenna 401.

As described above, the ultrasonic fat removal patch 200 according to the present invention can be applied to a desired part of the body of a user to radiate ultrasonic waves, thereby continuously varying the frequency band of ultrasonic waves, .

Further, since the flexible circuit board 305 is used as the circuit layer 305 for radiating ultrasonic waves, the elasticity of the pack made of a silicone material is improved, and the ultrasonic fat removal patch is stably stuck to the user's body part, It is possible to concentrate the body part of the body and increase the removal effect of the fat cells.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the appended claims. You will understand.
