Description

Electrical stimulation generator {ELECTRIC STIMULATION GENERATION APPARATUS}

The following description relates to an electrical stimulation generating device for generating electrical stimulation.

An electrical stimulation generator artificially generates a potential difference in a human body, applies an alternating electric field to the human body through an electrode, and stimulates blood vessels, muscles, etc. to obtain effects such as improvement of blood circulation. When the electric potential and current generated by the electrical stimulation generator are applied to the human body, an electric field is formed around the human body, and the sympathetic and parasympathetic nervous system of the body's autonomic nervous system are stimulated to adjust the biological imbalance and increase the homeostatic effect. Furthermore, it has various advantages such as purifying blood, improving autonomic nerves and hormone immunity, activating cells, promoting blood circulation and metabolism, and recovering from fatigue.

Through long-term studies, medium/low frequencies have been confirmed to be effective in removing subcutaneous fat and preventing skin aging. In the case of electric stimulation method using medium/low frequency, it usually uses a low frequency of 1,000 Hz or less and a medium frequency between 1,000 and 4,500 Hz. It is effective in relieving and improving blood circulation. When a low frequency is applied to the skin, the muscle repeats the stretching action to promote blood circulation, and the massage effect increases the metabolism of elastic fibers such as collagen and elastin, giving elasticity to the skin. And the low frequency used for medical purposes uses a low frequency of about 10~200Hz, similar to bioelectricity flowing through the human body, and stimulates muscles and nerves to relieve symptoms such as muscle paralysis, pain, and fatigue.

On the other hand, in general, the higher the frequency, the deeper the electrical stimulation applied to the skin reaches. That is, the low-frequency stimulation is applied to the skin surface, the medium-frequency stimulation penetrates up to 2-3 cm deep into the skin, and in the case of high frequency, it penetrates deeper.

However, due to the characteristics of the human body, when used in a part with a lot of muscle or a part with a relatively high water content, the amount of current increases and a voltage drop occurs. For this reason, the intensity of the stimulus acting according to the user at the same voltage is different. In addition, when continuous stimulation is applied to the same region, it is inconvenient to continuously adjust the frequency and time in order to change the strength of the stimulation.

Hereinafter, the electrical stimulation generating device 1 will be described with reference to FIGS. 1 to 6 . For reference, FIG. 1 is a perspective view of an electrical stimulation generating device according to an embodiment, and FIG. 2 is a perspective view of an electrode 30 according to an embodiment in the electrical stimulation generating device 1 of FIG. 1 . 3 to 6 are perspective views of the electrodes 40 , 50 , 60 , and 70 according to modified embodiments.

Referring to the drawings, the electrical stimulation generating device 1 is configured to include a body 10 and an electrode 30 . And if necessary, a hand piece 20 used by being coupled to the electrode 30 is provided.

The main body 10 is provided with a control circuit (not shown) for supplying power for generating electrical stimulation, generating an electric potential, and controlling the current applied to the electrode 30 .

The main body 10 illustrated in FIG. 1 is merely an example for convenience of description, and the shape and size of the main body 10 are not limited by the drawings, and substantially various sizes such as installation forms and portable forms and can be formed in the form

The electrode 30 is formed of a metal material, and is in direct contact with the subject's skin to generate a predetermined potential difference to apply electrical stimulation of a predetermined strength. The electrode 30 is configured to include a body 31 , stimulation portions 31a and 31b that are portions in contact with the subject's skin, and a coupling portion 32 coupled to the hand piece 20 .

For example, the body 31 is formed in a substantially cylindrical shape, magnetic pole portions 31a and 31b are formed at both ends of the body 31 , and the coupling portion 32 is formed in the middle in the longitudinal direction of the body 31 . It may be formed to protrude outward.

The magnetic pole parts 31a and 31b have a conical or conical shape whose cross-sectional area gradually decreases toward the ends. In addition, the second magnetic pole part 31b formed at the other end of the two magnetic pole parts 31a and 31b than the first magnetic pole part 31a formed at one end of the body 31 may have a sharper tip. Accordingly, both magnetic pole parts 31a and 31b may have different inclinations.

The stimulation parts 31a and 31b apply stimulation by directly contacting their front ends with the skin of the subject, and since the area in contact with the skin is small, stimulation of stronger intensity can be applied. Accordingly, the second magnetic pole part 31b may apply a stimulus having a stronger intensity than that of the first magnetic pole part 31a.

On the other hand, the body 31 may also come in direct contact with the subject's skin to apply stimulation, similarly to the stimulation units 31a and 31b. That is, stimulation may be applied by bringing the outer peripheral surface of the cylindrical surface of the body 31 into contact with the subject's skin. In addition, since the body 31 has a larger contact area than the magnetic pole parts 31a and 31b, the stimulus can be applied to a larger area than the magnetic pole parts 31a and 31b, and the stimulus can be applied with a lower intensity.

Here, in this embodiment, two magnetic pole parts 31a and 31b having different tip shapes and a body 31 formed to enable contact and stimulation on the outer circumferential surface are provided, so that one electrode 30 is used. Stimuli of different intensities can be applied to the subject. In addition, when it is desired to change the intensity of the stimulus, the intensity of the stimulus can be adjusted only by changing the position of the electrode 30 in contact with the subject's skin without adjusting the intensity or frequency of the applied current, It is easy to adjust and it is possible to prevent a delay in applying the stimulus. In addition, since the electrodes 30 can apply stimuli of different intensities, the stimuli can be appropriately applied according to the subject's sensitivity to the stimuli, thereby improving the subject's satisfaction.

The coupling portion 32 is a portion coupled to the hand piece 20 and is formed to extend a predetermined length from the outer circumferential surface of the body 31 outward in the radial direction. In addition, a fastening part 32a fastened to the hand piece 20 may be formed at an end of the coupling part 32, for example, the fastening part 32a may have a screw threaded bolt shape. However, this is merely an example for convenience of description, and the shapes of the coupling part 32 and the coupling part 32a are not limited by the drawings and may be substantially changed in various ways.

According to the present embodiments, since the electrode 30 is detachably formed, various types of electrodes 30 can be easily replaced as needed.

The hand piece 20 is coupled to the electrode 30 so that a user or operator can use it easily. The hand piece 20 is connected to the main body 10 and the power line 22 at one end of the body 21 part gripped by the operator's hand, and the coupling part 23 to which the electrode 30 is coupled is formed at the other end. do.

The body 21 of the hand piece 20 is formed of an insulating material so that the current generated in the body 10 and applied to the electrode 30 does not flow. In addition, the body 21 of the hand piece 20 has a shape that is easy to use and grip. Although the drawing illustrates that the body 21 of the hand piece 20 is formed in a substantially cylindrical shape, this is merely an example for convenience of description, and the shape and size of the body 21 can be substantially variously changed, In addition, it is also possible to omit the hand piece 20.

Meanwhile, the electrode 30 may have various shapes other than the above-described embodiments.

For example, as shown in FIGS. 3 to 4, the electrodes 40 and 50 have magnetic pole parts 41a, 51a, 51b formed at one end of the bodies 41 and 51, and a coupling part ( 42, 52) may have a formed shape.

In the electrode 40 shown in FIG. 3 , one magnetic pole part 41a is formed at one end of the body 41 and a coupling part 42 with a fastening part 42a with the hand piece 20 formed at the other end. It may be formed including In addition, the magnetic pole part 41a has a substantially rod shape, and is formed in a shape in which the cross-sectional area becomes gradually smaller toward the end. In this case, the size and sharpness of the tip of the magnetic pole part 41a may be variously changed as needed.

The electrode 50 shown in FIG. 4 is provided with spherical magnetic pole parts 51a and 51b at one end of the body 51 , and a coupling part 52a fastened to the hand piece 20 is formed at the other end of the body 51 . It may be formed to include a portion (52).

Here, the stimulation parts (51a, 51b) are formed to protrude from the body (51), at least a portion in contact with the subject's skin is formed in a curved shape such as a spherical or hemispherical shape. In addition, although the magnetic pole parts 51a and 51b are illustrated as having a rod shape with a predetermined length and extending from the portion connected to the body 51 , the spherical magnetic pole parts 51a and 51b are formed directly on the surface of the body 51 . It is also possible to have a shape.

In addition, a predetermined angle may be spaced apart between the two magnetic pole parts 51a and 51b to be inclined at a predetermined angle with respect to the body 51 . In addition, the magnetic pole parts 51a and 51b may be formed in spherical shapes having the same diameter or may be formed to have different diameters. Similarly, the size of the magnetic pole parts 51a and 51b may be variously changed as needed.

In the case of the electrode 50 according to the present embodiment, in the case of the spherical stimulation parts 51a and 51b, since the area in contact with the skin is relatively large, a weak stimulation can be applied to a large area. In addition, the electrode 50 is provided with the magnetic pole parts 51a and 51b spaced apart from each other by a predetermined distance so that they can be in contact between the two magnetic pole parts 51a and 51b. can be brought into contact at the same time.

On the other hand, while the electrodes 30 , 40 , and 50 according to the above-described embodiments have a form coupled to the hand piece 20 , the hand piece 20 is omitted and has a form directly connected to the body 10 . can

For example, according to FIGS. 5A and 5B , the electrode 60 includes a pad-shaped body 61 that is adhered to the skin, and a stimulation unit 61a that applies stimulation to the skin.

The body 61, for example, may be adhered to the skin and formed of an insulating material.

A coupling part 62 coupled to the coupling part 63 of the power line 64 may be provided on the rear surface of the body 61 . For example, the electrode 60-side coupler 62 and the power line 64-side coupler 63 may have a snap button shape that can be fitted with each other. However, this is only for convenience of description, and the shapes of both coupling portions 62 and 63 may be substantially changed in various ways.

The magnetic pole portion 61a may be formed to have a spherical shape or a curved surface having a predetermined curvature so as to apply a stimulus of an appropriate intensity to protrude from the surface of the body 61 . The stimulation unit 61a may be in approximately point contact with the skin to apply stimulation of a predetermined intensity. However, the size and shape of the magnetic pole portion 61a may be substantially variously changed according to the intensity of the magnetic pole to be applied.

Here, by attaching a plurality of electrodes 60 according to the present embodiment, stimulation may be applied to a plurality of positions at the same time. In addition, it is also possible to simultaneously apply stimulation of various intensities to a plurality of positions by attaching the electrode 60 having the stimulation portions 61a having different sizes to the electrode 60 .

In addition, the magnetic pole portion 61a may be formed to be replaceable in the body 61 . Alternatively, even if the magnetic pole portion 61a is integrally formed with the body 61 , a plurality of electrodes 60 having the magnetic pole portions 61a of various sizes may be connected to one body 10 .

As another embodiment, referring to FIG. 6 , the electrode 70 may have a shape that can be worn by a user. For example, the electrode 70 may include a glove-shaped body 71 , and one side of the body 71 may be connected to the body 10 through a power line 74 .

In this case, since the body 71 is directly worn by the user or the subject, the body 71 is formed of an insulating material except for the magnetic pole portion 71a.

The magnetic pole portion 71a may be formed at a position such as a finger or a palm, for example. The stimulation unit 71a may also be in contact with the subject's skin in the form of a surface contact to apply stimulation of a predetermined intensity. However, this is merely an example for convenience of description, and the position of the magnetic pole part 71a may be substantially changed in various ways. In addition, an insulating material is provided on the inner surface of the body 71 at a position corresponding to the magnetic pole portion 71a to prevent potential stimulation from being applied to a user using the electrode 70 .

One side of the body 71 is provided with a coupling portion 72 coupled to the coupling portion 73 of the power line 74, for example, the electrode 70 side coupling portion 72 and the power line 74) The side coupling portion 73 may have a snap button shape that can be fitted with each other. However, this is only for convenience of description, and the shapes of both coupling portions 72 and 73 may be substantially changed in various ways.

Here, the electrode 70 according to the present embodiment may be directly worn by the user to further apply a stimulus such as a stimulus according to a potential difference and a grip force applied by the user to the subject.
