As shown in these drawings, the muscle massage device of this embodiment includes a base pad 100, a low frequency generator 200 coupled to the center portion of the base pad 100, and an agent coupled to the inner surface of the base pad 100. 1 Protective film 300, the conductive electrode 400 formed on both sides of the low-frequency generator 200 on one side of the first protective film 300, and a portion of the conductive electrode 400 while covering a portion of the first protective film ( It includes a second protective film 500 coupled to the 300, and a gel pad 600 coupled to the first protective film 300 while covering the rest of the conductive electrode 400.

Looking specifically, the base pad 100 functions as a base member for positioning the conductive electrode on the inner surface. The base pad 100 is made of an elastic material that can be easily deformed in response to the bending of the body, for example, may be made of a silicone pad.

In addition, the base pad 100 has a width and a length sufficient to form a plurality of electrode pairs while being symmetrical in both right and left sides. The base pad 100 forms an integral structure in which the central portion and the left and right portions are connected to each other. Therefore, the user can easily wear it by matching the central portion to the center of the abdomen or the center of the waist, and then attaching the left and right ends to both sides so as to wind the abdomen or waist, respectively.

The low frequency generator 200 is configured to generate a low frequency current, and is coupled to the center portion of the base pad 100. The low frequency generator 200 may be configured as a module that generates a low frequency from an external power source or a charging power source, and a detailed description of the low frequency generator 200 will be described later.

The first protective film 300 is configured to protect the conductive electrode 400 by being coupled to the inner surface of the base pad 100, and blocks the conductive electrode 400 from being directly formed on the base pad 100 having excellent elasticity. . That is, the conductive electrode 400 is formed on the inner surface of the base pad 100 through the first protective film 300.

In addition, the first protective film 300 may be composed of a sheet or film material having a smaller elastic force than the base pad 100, for example, PET (Polyethylene terephthalate), PS (Poly styrene), PP (Polypropylene) or It can be composed of films such as PC (Polycarbonate). The first protective film 300 tries to maintain its shape despite the elastic deformation of the base pad 100, thereby preventing damage to the conductive electrode 400 due to the deformation of the base pad 100.

In addition, the first protective film 300 may have a shape corresponding to the base pad 100, and it is preferable that the area has a relatively small area than the base pad 100. That is, the edge of the first protective film 300 has a shape located inside the edge of the base pad 100. Since the first protective film 300 has low elasticity and can be easily damaged by an external shock, it can be protected from external shock by the edge of the base pad 100.

The conductive electrode 400 is configured to transmit current generated by the low-frequency generator 200 to the body, and a metal material having excellent conductivity is coated on the first protective film 300 or the conductive film is applied to the first protective film 300. It can be constructed by bonding. The conductive electrode 400 forms a symmetrical structure with respect to the left and right sides based on the center portion of the base pad 100.

Referring to FIG. 2, the conductive electrode 400 of the present embodiment is a pair of first electrodes 410 disposed near upper and lower left and right sides with respect to the low-frequency generator 200 and outside the first electrode 410. It is composed of a pair of second electrodes 420 arranged on the left and right sides, and a pair of third electrodes 430 arranged on the left and right sides of the first electrode 410. Each electrode 410,420,430 is connected to the low-frequency generator 200 by a line electrode 440.

In the present embodiment, the first electrode 410 stimulates the rectus abdominis muscle and multifidus muscle in the body, and the second electrode 420 is an internal oblique muscle in the body.筋) and the external oblique muscle (外腹斜筋) to stimulate, the third electrode 430 is disposed in a position to stimulate the transverse abdominal muscle (腹橫筋) and the major pectoralis (大腰筋). Here, the rectus abdominis muscle is a muscle that is up and down along the front, left, and right of the abdomen, and is used when bending the spine forward. The multifidus muscle is a muscle attached to the spine and contributes to stable posture control of the spine. The external oblique muscle is located on the shallowest layer of the side abdomen, the internal oblique muscle is located on the lower layer, and the external oblique and internal oblique muscles are related to the waist line. The transverse abdominis is located in the deepest part of the lateral abdomen and is related to the waist line. The major pectoralis is located around the pelvis, and functions to support and support the pelvis.

The second protective film 500 is configured to protect the conductive electrode 400, in particular, the line electrode 440, and covers each line electrode 440 including a part of the first to third electrodes 410, 420 and 430. 1 It is combined with a protective film. The second protective film 500 may be made of a sheet or film of the same material as the first protective film, and is limited to any material that can be easily coupled to the first protective film 300 while protecting the line electrode 440 Does not work.

The conductive electrode 400 may be damaged due to repeated use, impact with an external object, interference, etc., but the second protective film 500 prevents damage to the conductive electrode 400 to the outside.

The gel pad 600 protects the first to third electrodes 410, 420, and 430, so that the current delivered to each electrode is easily absorbed into the body. The gel pad 600 may be formed of a conductive material in a gel state, and is coupled to the first protective film 300 while covering each electrode 410,420,430.

The gel pad 600 is a material configured to serve as an interface between each electrode 410,420,430 and the skin interface. The muscle massage device is a method of treating pain caused by various causes by stimulating the peripheral sensory nerves of the skin using an electric current, and the conductive material in a gel state is configured to satisfy an electrical property such as impedance by containing an appropriate electrolyte, It is configured to deliver an accurate signal to the treatment site.

Meanwhile, although not shown, a peeling film may be further bonded to the surface of the gel pad 600 to protect the gel pad 600.

The muscle massage device using the electrical stimulation of the above configuration, the gel pad 600 is used in a state of being adhered to the surface of the body, and each pair of electrodes is formed on an integral base pad to facilitate user manipulation. have. In addition, both sides of the conductive electrode may be protected by a protective film, thereby protecting the base pad from deformation and contact with foreign materials.

4 is a block diagram showing the main configuration of a low-frequency generator according to this embodiment.

As illustrated, the low frequency generator 200 includes a signal generator 220 for generating a low frequency current, a signal output unit 230 for outputting the generated signal, a manipulation unit 240 for user manipulation, and a driving state It includes a display unit 250 for displaying, and a power supply unit 260 and a control unit 210 that receives power and provides it to the signal generator 220.

The control unit 210 controls the driving of the signal generation unit 220, the signal output unit 230, the operation unit 240, the display unit 250, and the power unit 260, and the overall driving of the low-frequency generator 200. The control unit 210 may be configured as a main control unit (MCU) in which a predetermined program is embedded.

The signal generator 220 generates a low-frequency current as the power provided by the power supply unit 260. The low-frequency generator 200 of the present embodiment is configured to supply a fundamental wave to the body by loading the carrier wave. Therefore, the signal generator 220 generates fundamental wave and carrier currents of different wavelengths.

The signal generator 220 of this embodiment generates a frequency of 1,000 Hz to 5,000 Hz as a fundamental frequency (basic wave), and is preferably configured to generate a frequency of 2,500 Hz band. Since the frequency between 1,000Hz and 5,000Hz is relatively higher than the low frequency, it can be viewed as a medium frequency. The resistance of the skin of the body appears to be approximately 50 Ω to 500 Ω, and the frequency between 1,000 Hz and 5,000 Hz for this skin resistance does not cause a great irritation to the body, so there is little reluctance when used.

In addition, the signal generator 220 of the present embodiment generates a frequency of 4 Hz to 70 Hz as a carrier frequency (carrier). The lower the frequency band, the higher the tension (stretching force) generated in the muscles, so the lower frequency band in the above range has an advantageous effect to train the muscles.

In addition, the signal generator 220 is configured to generate a plurality of carrier frequencies in a frequency range between 4 Hz and 70 Hz, for example, may generate different frequencies of 17.5 Hz and 35 Hz. When stimulating the muscles at the same frequency, the muscles develop resistance and the muscle's tensile strength may decrease. Therefore, when repeatedly stimulating at different frequencies as in the present embodiment, it is possible to prevent the occurrence of muscle tolerance. Although illustrated in this embodiment as generating two types of carrier frequencies, up to 10 different types of carrier frequencies can be generated, and at this time, each frequency is configured to be randomly generated.

The signal output unit 230 is configured to output the signal generated by the signal generation unit 220 to the conductive electrode 400, and transmits the fundamental wave to each electrode 410,420,430 on a carrier wave.

The manipulation unit 240 is configured to receive user manipulation, and is configured to expose manipulation buttons to the front of the base pad 100. The manipulation unit 240 may include a power on/off module, a stimulus intensity control module, and the like.

The display unit 250 is configured to display the driving state of the muscle massage device, and is configured to expose the display lamp to the front of the base pad 100. The display unit 250 may include a low-frequency generation status display lamp, a charging status display lamp, and the like.

The power supply unit 260 is configured to receive external power and provide it to the signal generator 220 or store it in an internal charging module. The power supply unit 260 may include a connection module capable of connecting to a power supply and a charging module for charging.

5 and 6 are views showing an example of using the muscle massage device of the present embodiment, respectively, showing a state worn on the abdomen in front of the body and the waist on the back.

First, referring to Figure 5, the muscle massage device can be worn on the abdomen in front of the body. The muscle massage device worn on the front of the body stimulates the rectus abdominis, the abdominal muscles and the transverse abdominis. Specifically, the first electrode 410 of the pair stimulates the rectus abdominis muscle, the second electrode 420 of the pair stimulates the inner abdominal muscle, and the third electrode 430 of the pair stimulates the abdominal muscle.

In addition, referring to Figure 6, the muscle massage device can be worn on the back of the body. The muscle massage device worn on the back of the body stimulates the multifidus muscle, the external oblique muscle, and the major psoas muscle. Specifically, the first electrode 410 of the pair stimulates the multifidus muscle, the second electrode 420 of the pair stimulates the external oblique muscle, and the third electrode 430 of the pair stimulates the psoas muscle.

As described above, the muscle massage device of the present embodiment is configured such that each electrode is positioned at a different location, and can effectively act on specific muscles around the pelvis at the front and back of the body.
