Photothermal puffer for eyelids

Abstract

At present, no clear evaluation has been made on the blood circulation-promoting effect of the conventional thermal or optical palpebral polyp. In addition, there is no simple eyelid thermometer capable of confirming the blood circulation promoting effect on the spot.SOLUTION: Since the blood flow and the temperature are correlated in the anterior eye tissue, it is possible to significantly increase the lid temperature by using the heat stimulus in addition to the light stimulus of 740nm that increases the lid temperature. In addition, by using digital thermotapes of 34 °C and 36 °C as a thermometer of the eyelid, it is possible to check a change in eyelid temperature on the spot after the use of the intraocular pressure monitor for eyelid. As a result, it is possible to recover or improve eyesight due to eye fatigue or the like and to use the device as a blood flow checker of the eye. In addition, it can also be used for improving poor blood circulation sites other than the eyelid.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a photothermal and light-activated eyelid anpo device that promotes blood circulation in the eyelid by using both light and heat stimulation, and the resulting increase in eyelid temperature can be confirmed using digital thermotape. [Background technology]

[0002] Recently, eyelid massagers that incorporate a massage function in addition to the heat stimulation provided by hot eye masks have been commercialized. However, it has been pointed out that these devices are heavy and large in size due to the load of vibration and pressure functions.

[0003] Regarding the light and heat stimulation caused by the hot eye mask, the light stimulation is a photothermal effect of 740 nm, and a comparison of "700-800 nm LED radiation heat (℃)" on the thumb shown in [Table 1] of

[0014] as an example in [Patent Document 1, Patent Application No. 2023-81899] shows that the skin temperature rises due to the radiation heat of 740 nm.

[0004] On the other hand, in [Non-Patent Document 1], the results showed that thermal stimulation did not result in any effects such as recovery of eye accommodation function. However, thermal stimulation around the eyes is said to induce a pleasant feeling. However, light stimulation is not a thermal stimulation, so it cannot induce a pleasant feeling due to heat.

[0005] Regarding the relationship between blood flow and temperature in the anterior segment of the eye, as shown in [Non-Patent Document 2], "blood flow and temperature are correlated in the anterior segment of the eye tissue," and an increase in temperature indicates an increase in blood flow.

[0006] Furthermore, it was previously thought that there was no relationship between visible light stimulation and thermal stimulation, but as shown in [Non-Patent Document 3], it has been shown that the combined use of thermal stimulation and optical (visible light) stimulation significantly increases the power.

[0011] It is difficult to achieve a blood circulation promoting effect by heat stimulation to the eyelids alone, and it is also difficult to induce a positive emotion in the brain by light stimulation alone.

[0012] The present invention aims to provide a combined light-and-heat anpo device for the eyelids that uses both heat and light stimulation, increasing the eyelid temperature by promoting blood circulation to the eyelids and simultaneously inducing a feeling of well-being in the brain, and further incorporating a thermometer so that the user can check the change in eyelid temperature for themselves. [Means for solving the problem]

[0013] The ampo device of the present invention is an ampo device that adds thermal stimulation to the conventional light stimulation of the eyelid light ampo device, and can be used as a light-heat ampo device by covering the eyelid light ampo device with a hot eye mask that provides thermal stimulation, as shown in Figure 1. It can be combined with a hot eye mask that uses steam or electric heat as a thermal stimulation. [Effects of the Invention]

[0014] [Table 1]

[0015] The effect of the photothermal and light-induced eyelid anpou device of the present invention is shown in the example of "Eyelid temperature increase (°C) due to photothermal and combined photothermal stimulation" in [Table 1] of

[0014] . In the example, when a photothermal stimulation using both light and heat was compared with a light stimulation using only light and a heat stimulation using only heat, the photothermal stimulation produced the highest increase in eyelid temperature, and the increased eyelid temperature was maintained for approximately 30 minutes.

[0016] As shown in the examples in [Table 1] of

[0014] , the result of the increase in eyelid temperature using a photothermal eyelid ampoule is thought to be similar to the phenomenon reported in the research report in [Non-Patent Document 3], whereby irradiating a heated object with visible light (740 nm in the example) further increases the power of the object.

[0017] Eyelid temperature is measured by placing a photothermal eyelid pressure device with a digital thermo tape attached on the eyelid for approximately 30 seconds before and after use.

[0018] Record the temperature on the memo card in [Table 2]. To use, slide the paper clip on the memo card on the right of [Table 2] to record the changes before and after use. The measurement temperature range is based on the upper limit of eyelid temperature being approximately 36°C.

[0018] [Table 2]

[0019] The blood circulation-promoting effect of the eyelid light-heat combination ampoule is expected to be effective in slowing the progression of myopia and improving poor blood circulation in areas other than the eyelids. [Brief explanation of the drawings]

[0020] [Figure 1] FIG. 1 is an explanatory diagram of a light-heat combination eyelid anpō device 1 showing an embodiment in which an eyelid anpō device 4 and a steam hot eye mask 2 are combined.

[0021] [Figure 2] FIG. 1 is an explanatory diagram of an embodiment of an eyelid ampoule 1 with both light and heat, in which an eyelid ampoule 4 is incorporated into an electric hot eye mask 3. DETAILED DESCRIPTION OF THE INVENTION

[0022] Figure 1 shows a disposable steam hot eye mask 2 that uses steam heat to warm the eyelids. By covering a conventional eyeglass-type light eyelid ampoule 4, it can be used as a light and heat ampoule 1 for the eyelids.

[0023] Figure 2 shows a conventional eyelid anpō 4 with the glasses 5 removed and incorporated into an electric hot eye mask 3, which is also used as a light-heat combined eyelid anpō 1.

[0024] The optical eyelid ampoule 4 used in Figures 1 and 2 is configured by attaching a sponge pad 7 and a board 6 equipped with a 740 nm far-red light LED 8 to glasses 5, and attaching digital thermo tape 9 of 34°C and 36°C to the sponge pad 7.

[0025] When attaching the eyelid light ampoule 4 to the electric hot eye mask 3 as shown in Figure 2, it is attached to the inside of the electric hot eye mask 3 instead of the glasses 5. The sposipad 7 is removable and can be attached to either the left or right side. Power is supplied from an AC adapter (not shown) or the like.

[0026] The procedure for use is explained below. The eyelids are closed when using the device. Before placing the eyelid light-heat and ampoule device 1 shown in Figures 1 and 2 on the eyelids, for safety and hygiene reasons, cover the eyelid light-heat and ampoule device 1 with food wrap that adheres to the skin to prevent the digital thermo tape 6 from coming into direct contact with the skin.

[0027] The usage time is set using a timer, and the temperature is measured for approximately 30 seconds before use. In the case of [Figure 1], the steam hot eye mask 2 is removed from the eyelids after 5 minutes of use, and the temperature is measured for approximately 30 seconds after use and recorded on a memo card. In the case of [Figure 2], the temperature is measured before use as in [Figure 1], and the eyelid light anpowder 4 is turned off after 1 minute of use, and then the electric hot eye mask 3 is turned off after a further 4 minutes of use (5 minutes in total), and the temperature is measured for approximately 30 seconds after use and recorded on a memo card.

Claims

[Claim 1] To promote blood circulation in the eyes, which is effective for restoring eyesight, a 740nm light stimulation anpo, which emits visible red light onto the eyelids, is used in combination with a conventional heat stimulation anpo to promote blood circulation, significantly increasing eyelid temperature, and this increased temperature can be maintained for approximately 30 minutes.At the same time, by attaching digital thermo tape measuring 34°C and 36°C to the light-heat anpo, the user can immediately check the change in eyelid temperature.
