JP2020044307A - Red light poultice device - Google Patents

Abstract

To provide a poultice device with which skin temperature rises even after a lapse of about 20 minutes after the use of one minute.SOLUTION: The red light poultice device can obtain blood circulation promotion effect of the subcutaneous vascular network by using light having a peak wavelength of 740-760 nm. The light of 740-760 nm reaches the subcutaneous vascular network of the skin with treatment time of one minute and is absorbed to promote blood circulation in the skin of a part such as eyelid. In addition, by measuring a change in the skin temperature, increase in the blood flow rate after the treatment can be ensured.SELECTED DRAWING: Figure 1

Description

TECHNICAL FIELD The present invention relates to a red light amplifier that can obtain a blood circulation promoting effect of a subcutaneous vascular network by using light having a peak wavelength of 740 nm to 760 nm.

Conventional hyperthermia includes a method using heat transfer such as a hot pack or a hot bath, and phototherapy includes an infrared therapy device. As an ankle for eyelid, there is an ankle for one eye using a red LED of 740 nm (for example, Patent Document 1).

In addition, the infrared therapy device uses a wide range of light from the infrared region of 770 nm to 12,000 nm. On the other hand, the red light amplifier according to the present applicant's proposal using a specific wavelength is based on the premise that light of a specific wavelength reaches deep tissue of the skin (Non-Patent Document 1).

The problem to be solved is that the temperature of the skin decreases after use or hot water, because hot packs or hot baths, which aim to promote blood circulation by heat transfer, warm the skin to the epidermis. Is that the skin temperature returns to the original skin temperature, and the effect of promoting blood circulation cannot be obtained.

The present invention is to irradiate the red light angulas of 740 nm to 760 nm, which is a specific wavelength, for 1 minute, so that the red light of the anpanzer reaches the subcutaneous vascular network and is absorbed, thereby promoting blood circulation. Skin temperature also increases. As a result, the skin temperature rises about 20 minutes after use for 1 minute.

The present invention increases blood flow in a short one-minute use, and in addition, it is the blood flow that governs skin temperature (Japanese Society of Thermology), which promotes blood circulation and increases blood flow. Skin temperature rises. Therefore, by measuring the skin temperature, it is possible to confirm a change in blood flow in the skin.

  It is explanatory drawing which showed the implementation method for the eyelid of this invention.   It is explanatory drawing which showed the implementation method other than for eyelids of this invention.

The red light amplifier 1 is powered by a USB power supply or two AAA batteries. When AAA batteries are used, a AAA battery box can be used in the main body case. In addition, one red LED 4 can be used for the eyelid, and two or more red LEDs 4 can be used in addition to the eyelid if necessary. If necessary, a wrap film may be used so that the pad 3 does not directly touch the skin.

FIG. 1 shows an embodiment of the eyelid according to the present invention, in which 1 is a red light amplifier, and a sponge pad 3 is mounted on a main body case 2. One 740 nm red LED 4 is provided at the center of the pad 3 and connected to the power switch 5 of the main body case 2. As the power source, a USB power cord 6 is used to use a USB power source.

FIG. 2 shows an embodiment other than for the eyelid, in which the shape of the pad 3 is larger than that for the eyelid, and the power source is a dry battery in order to make it a handy type, which is a skin disease caused by insufficient blood flow. It can also be used as an angiosurgery device for pressure ulcers or for hair growth. Also, depending on the size of the skin disease, a plurality of red light lamps 1 can be used.

Hereinafter, the use procedure will be described. 1 and 2 are the same. First, connect the USB power cable 6 to the AC adapter or check the batteries, then turn on the power switch 5 of the main body case 2 to turn on the 740 nm red LED 4. After confirming the lighting, apply to the eyelid or a part other than the eyelid for one minute. A use time of one minute is sufficient, but one minute or more can be used. If necessary, a one-minute timer can be incorporated.

Table 1 above shows the measured values of the eyelid skin temperature after use by applying the red light ampoule to the eyelids for 1 minute, and the skin temperature is increased 10 minutes after use. The skin temperature was measured with a thermocouple thermometer.

The following Table 2 is a table of (skin tissue and infrared radiation ratio) of Non-Patent Document 1, and since the unit of the wavelength is indicated by a micrometer (μ), 740 nm becomes 0.74 μ. From this table, the wavelength around 0.75μ penetrates the skin tissue most deeply, reaches 25% in the subcutaneous tissue, and reaches 5% in the deep tissue and is absorbed, thereby promoting blood circulation in the subcutaneous vascular network. A comparison of the blood flow with 700 nm light and 740 nm light shows that 740 nm is increased by 5 to 10%.

Claims (1)

  With a short treatment time of 1 minute, it reaches the subcutaneous vascular network of the skin and is absorbed, and the peak wavelength for promoting blood circulation is 740 nm to 760 nm. As a method of promoting blood circulation and confirming an increase in blood flow after treatment, an increase in blood flow can be confirmed by measuring changes in skin temperature.
