Abstract

[Problem] There is currently no clear evaluation of the blood circulation promotion effect, which is the purpose of eyelid massagers. In addition, there is no easy-to-use measuring device to check the blood circulation promotion effect on the spot.
[Solution] Since eyelid temperature and blood flow are correlated, the change in eyelid temperature can be confirmed on the spot from the change in eyelid temperature by using a digital thermo tape attached to the light-squeezing device. The far-infrared 740 nm LED used in the light-squeezing device has a large radiant heat generating power, and has a large effect on promoting blood circulation along with its ability to penetrate the skin. In addition, the digital thermo tape does not measure accurate temperature, but has a fast reaction speed, making it suitable for knowing temperature changes. As a result, the light-squeezing device for eyelids of the present invention is used in eye clinics to treat eye fatigue, etc., but can also be used in beauty salons due to its effect of promoting blood circulation around the eyes, and can also be used for eye health management at home.

Description

The present invention relates to an optical eyelid massager equipped with a digital thermotape that promotes blood circulation in the skin and allows the results to be confirmed.

As for eyelid massage devices, hot eye masks and other thermotherapy using heat stimulation are the most widely used, but because conductive heat transfer from thermal stimulation is absorbed by the skin surface, it is said that they cannot be expected to have an effect on promoting blood circulation in the eyelids (Non-Patent Document 1).

Regarding thermal stimulation to the skin, the change in average skin temperature accompanying bathing shows that the skin temperature rises during bathing, but falls below the skin temperature before bathing 10 minutes after the water is removed (Non-Patent Document 2). However, the body temperature remains higher than before bathing until 10 minutes after the water is removed. For this reason, it is thought that thermal stimulation to the skin does not promote blood circulation, and the rise in skin temperature cannot be maintained.

On the other hand, eyelid skin temperature is correlated with eyelid blood flow, and as eyelid blood flow increases, eyelid skin temperature also increases (Non-Patent Document 3). As a result, in actual test results, the eyelid skin temperature increases due to light stimulation, and the increased temperature is maintained even after 10 minutes.

A conventional eyelid light stimulator (Patent Document 1) uses 740 nm and 750 nm far-red LEDs as light stimuli, but only the use of a 740 nm far-red LED is effective [0014] [Table 1]. Also, a 34°C digital thermo tape is used as a skin thermometer, but in order to expand the measurement temperature range, it is necessary to add a 36°C digital thermo tape.

Conventional eyelid massagers mainly use heat stimulation, and there is no clear evaluation of their intended effect of promoting blood circulation. On the other hand, there is an issue with massagers that use light stimulation, in that it is not possible to confirm their effect of promoting blood circulation.

The purpose of this invention is to confirm the change in skin temperature at a certain surface contact pressure using digital thermo tape attached to glasses as a result of promoting blood flow to the skin of the eyelids and other areas through the light stimulation of a light pressure massager.

As shown in Figure 1, the ampo-ki device of the present invention has a means of placing one 740 nm LED, which acts as a light stimulus, on a substrate for both eyes, and placing digital thermotapes of 34°C and 36°C on the heater pad surrounding it, making it possible to confirm changes in eyelid temperature due to light stimulus.

The effect of 740 nm light in the present invention is shown in [Table 1] of [0014], in the example of "radiant heat generation from 700-800 nm LEDs" which is considered to be far-red. In the example, each LED from 700 nm to 800 nm was irradiated for 1 minute, and the temperature difference before and after irradiation was measured with a thermistor thermometer. As a result, it is considered that 740 nm light has a large radiant heat generation power, and has a large effect on promoting blood circulation as well as its penetration into the skin.

By adding a 36°C digital thermo tape to the 34°C digital thermo tape used in the present invention for measuring eyelid temperature, as shown in Figure 1, it is possible to confirm temperature changes in the range of 32.5 to 36.0°C, which is the limit of skin temperature rise of approximately 36°C. In addition, a memo card [0016] [Table 2] is used to record the color change of the digital thermo tape before and after using the light ampoule, and the memo card on the right of [Table 2] shows an example of using a paper clip. The digital thermo tape does not measure accurate temperature, but has a fast response speed, making it suitable for finding out temperature changes.

By concentrating the far-infrared light used in the eyelid light massager into a 740 nm LED, it is possible to shorten the light stimulation time to one minute, and by using a contact-type, power-free digital thermotape as a skin thermometer, it is possible to check eyelid temperature changes on the spot.

FIG. 13 is an explanatory diagram showing an embodiment of an optical ambo tool equipped with a digital thermo tape.

Fig. 1 shows an embodiment of the optical eyelid ampoule of the present invention. In Fig. 1, the optical eyelid ampoule 1 is configured by attaching a substrate 3 on which a sponge pad 4 and a far-red 740 nm LED 5 are mounted to glasses 2, and attaching digital thermo tapes 6 of 36°C and 34°C to the sponge pad 4. The sponge pad 4 is removable and can be switched between left and right. Power is connected to the substrate 3 from an AC adapter (not shown) via a switch box 7.

The procedure for use is as follows: Before attaching the eyelid light ampoule 1 and putting on the glasses 2, cover the glasses 2 with food wrap film, which is safe, hygienic, and has good adhesion, to prevent the digital thermo tape 6 from coming into direct contact with the skin.

First, wear the glasses 2 with the eyelid light pressure device 1 attached for 30 seconds, and read the eyelid temperature before use from the digital thermo tape 6 and record it on a memo card. Next, put on the glasses 2 and turn on the switch 8 of the switch box 7 connected to the AC adapter. The far-red 740 nm LED 5 lights up, and after one minute the buzzer sounds and goes off. Then read the digital thermo tape 6 and record it on a memo card to confirm the change before and after use.

In the embodiment, the eyelid temperature after use with the eyelid light ampoule 1 increases by 0.5 to 1.0°C, and depending on the conditions, the temperature may increase even more. However, the extent of the increase varies depending on the room temperature, physical condition, etc.

The reading of the Digital Thermo Tape 6 is quick (within 1 second) in response to temperature changes, and changes over time, so if there is a delay, put the glasses back on your eyes for about 5 seconds and check. The reading of the Digital Thermo Tape 6 is done by reading the color that changes every 0.5°C, and recording the corresponding temperature display point from the color of the memo card and the skin temperature with a paper clip, and checking the changes before and after use.

The optical eyelid massager of the present invention is used in eye clinics because of its effect of improving blood flow to treat tired eyes, but it can also be used in beauty salons because of its effect of promoting blood flow around the eyes, and it can also be used at home to manage eye health by knowing the state of eye blood flow.

Claims (1)

This light-based eyelid massager uses light stimulation from far-red LEDs, which are contained in sunlight and have a peak wavelength of 740 nm, to promote blood flow to the eyelid skin. By attaching digital thermotapes measuring 34°C and 36°C to the light-based eyelid massager as a skin thermometer to measure changes in skin temperature due to promoted blood circulation, the effect of promoting blood circulation and the associated changes in skin temperature can be confirmed on the spot.
