Description

Optical thermal massage device {Optical thermal massage device}

The present disclosure relates to an optical thermal massage device, and more particularly, to a pad-type or glove-type thermal massage device using LEDs.

Various types of beauty/health-related thermal massage devices using LEDs supply light waves from the LEDs to the dermis through the skin. Such a thermal massage device has various forms, such as a mask covering a face, a belly band that can be wrapped around a waist, and a patch that locally adheres to the body.

Attention should be paid to thermal images when using these conventional massage devices. Thermal burns can occur when exposed to strong light output from LEDs for a long time. Apart from such a thermal image, the conventional massage device has a structure that heats a specific part as a whole, and if thermal saturation is shown as a whole without a thermal gradient in the heated part, it is difficult to improve the blood flow.

Therefore, there is a need for research on a thermal massage device capable of suppressing thermal burns and improving blood flow effectively according to high power of LEDs.

The LED applied to the exemplary embodiments described below and the body in which it is installed are not limited to a specific structure.

1 is a schematic perspective view of a pad-type optical thermal massage device according to an exemplary embodiment, and FIG. 2 is a side view thereof.

1 and 2, the body 10 in the form of a cushion or pillow of the pad-type optical thermal massage device 1 has opposite sides, and the body 10 is made of natural or synthetic fibers, or natural or artificial fibers. It can be made of various materials such as leather.

The surface of the body 10 corresponds to the skin contact surface 14 that will face the skin of the living body, and a plurality of light emitting regions 14a, 14b, and 14c are defined on the skin contact surface 14 , and a plurality of LEDs 11 are disposed in each of these light emitting regions 14a, 14b, and 14c. The portion between the plurality of light-emitting areas 14a, 14b, and 14c, outside the plurality of light-emitting areas 14a, 14b, and 14c, is a non-light-emitting area where LEDs are not installed, and is a skin area. Light waves are not applied to the corresponding part to maintain a normal temperature and a relatively low temperature for the plurality of light emitting regions 14a, 14b, and 14c. The distance between the plurality of light-emitting regions 14a, 14b, and 14c, that is, the width of the non-light-emitting region may be set to about 3 to 5 cm.

As shown in the drawing indicated by “A” in FIG. 1, the LED 11 is provided in a light emitting head 11h in which a light emitting chip 11a is embedded and a lower portion of the light emitting head 11h. A pair of leads 11a and 11c for supplying current to 11a are provided.

A plurality of LEDs 11 are distributed and disposed in the light emitting regions 14a, 14b, and 14c set on the skin contact surface 14 below and/or below the upper part of the body 10, and the LEDs 11 The light emitting head 11h is installed to protrude from the skin contact surface 14 at a predetermined height, and the leads 11a and 11c are connected to the current supply circuit board 15 provided inside the main body 10.

A control panel 12 for controlling the LED 11 and a power supply jack 13 for supplying power are provided on one side of the skin contact surface 14.

The current supply circuit board 15 is a control element connected to the control panel 12 to control current supply to the LEDs 11, and power from the power supply jack 13 to the LEDs. Equipped with wiring, etc. supplied to (11).

According to the optical thermal massage device having the above structure, there is a part to which light waves are supplied and a part to which light waves are not supplied to the skin.

3 schematically illustrates a state when the optical thermal massage device is in contact with the skin 3.

Referring to Figure 3, the optical thermal massage device is attached to the skin, and the first part that touches the skin 3 is the light emitting head 11h of the LED 11, and this part presses the skin 3 to the epidermal layer. A U-shaped concave skin deformation portion 3a extending from the dermal layer to the dermal layer is formed, so that the front end of the light emitting head 11h is very close to the dermal layer 32 above the subcutaneous tissue layer 33.

In this way, the light emitting head 11h of the LED 11 comes close to the dermal layer 32, and the amount of light emitted by the LED 11 is reduced compared to the past. Conventionally, the LED has a structure in which it does not protrude from the skin contact surface 14 and retreats backward. Therefore, the distance between the light emitting head of the LED and the dermal layer becomes farther, and therefore, in order to supply sufficient light waves to the skin, the amount of power must be increased. . The supply of electric power consequently increases the amount of light emitted by the LED. The increased light emission of the LED causes a thermal image on the skin, and in this thermal image, light waves are strongly supplied from the LED away from the skin to the entire lower skin. Therefore, skin exposed to strong light waves is thermally damaged.

However, according to the present invention, the light emitting head of the LED is deeply embedded in the surface of the skin, that is, penetrates deep into the skin to form a concave skin deformation part in the skin, so that the light emitting head completely adheres to the skin deformation part surrounding it. Even if it is lowered sufficiently compared to the dermal layer, it is possible to sufficiently supply light waves to the dermal layer. At this time, since the light emitting head is embedded in the skin deformation part, the light wave is supplied only to the skin part in close contact with the light emitting head, and it is difficult to supply the light wave to other parts. According to this principle, as shown in FIG. 3, a high-temperature region at a portion where the light emitting head 11h is in contact and a low-temperature region away from the light emitting region in which the light emitting head 11h is provided are formed.

The formation of the high-temperature region and the low-temperature region as described above forms a thermal imbalance or thermal gradient with respect to the dermal layer, thereby improving blood flow through blood vessels under the dermal layer and capillaries expanding therefrom. Improvement of blood flow causes a difference in local blood density according to a thermal gradient, and blood flow is increased by this density difference.

4 illustrates the arrangement of light emitting regions of different wavelengths in the optical thermal massage device according to the present embodiment.

Referring to FIG. 4, four light emitting regions 14a, 14b, 14c, and 14d are defined on the skin contact surface 14. Among them, the first and fourth light emitting regions 14a and 14d are 600 nm visible light LEDs. may be installed, and near infrared LEDs of 800 nm may be installed in the second and third light emitting regions 14b and 14c. The distance between these light emitting regions is maintained at 3 to 5 cm as described above.

As is well known, a wavelength near 600 nm supplies heat to the subcutaneous tissue to thermally massage, and a wavelength near 800 nm is supplied subcutaneously to relieve inflammation. Light waves having such advantages must be supplied subcutaneously in an appropriate amount. Conventionally, since the light emitting head is not in close contact with the skin and is far away from it, the output must be significantly increased to supply the necessary energy to the subcutaneous skin. In this case, thermal imaging of the entire skin can cause However, the optical thermal massage device according to the present disclosure lowers the light output of the LED by making the LED not only directly contact the skin but also penetrates deeply under the epidermal layer and is placed very close to the subcutaneous dermis layer, and also reduces the thermal image of the skin due to excessive output. can prevent

5 illustrates a glove-type thermal massage device 2 according to another embodiment of the present disclosure.

12 is a photograph showing a part of the inside of the glove-type optical thermal massage device.

As shown in FIG. 12, a light emitting area is defined on the skin contact surface corresponding to the palm and back of the hand, and a plurality of LEDs are installed there.

In addition, since a plurality of light-emitting areas are provided with non-light-emitting areas interposed therebetween, a temperature gradient is generated by forming a high-temperature portion by LED and a relatively low-temperature portion therebetween, thereby increasing blood flow, thereby reducing the desired effect of an optical thermal mask. objective can be achieved more effectively.
