Photothermal fomentation instrument for eyelids

Abstract

To solve the problem that the blood circulation promoting effect of a conventional heat or light based eyelid fomentation instrument is not clearly evaluated at present and to solve the problem that there is no simple eyelid thermometer capable of confirming a blood circulation promoting effect on the spot.SOLUTION: Since the blood flow and the temperature are correlated with each other in the anterior ocular segment tissue, it has become possible to significantly increase the temperature of the eyelids by using the thermal stimulation in combination with the light stimulation of the 740 nm that increases the temperature of the eyelids. In addition, by using digital thermo tapes of 34°C and 36°C as a thermometer of the eyelid, it is possible to confirm a change in the eyelid temperature on the spot after using a photothermal fomentation instrument for eyelids. As a result, the photothermal fomentation instrument for eyelids cannot only relive an eyestrain, but also can be used as a home eye thermometer as a blood flow checker.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a light-heat combination eyelid anpo device that promotes blood circulation in the eyelid by using both light and heat stimulation, and the results of which 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 bulky due to the load of vibration and pressure functions.

[0003] Regarding thermal and optical stimulation (patent documents, Patent Application No. 2023-81899 and non-patent documents), when comparing the changes in skin temperature due to the blood circulation promoting effects of thermal and optical stimulation, it is said that the radiant power to the skin from 740 nm optical stimulation is greater than that of thermal stimulation.

[0004] On the other hand, no effects such as recovery of eye accommodation function due to thermal stimulation were observed, but thermal stimulation around the eyes is said to have an effect that cannot be obtained with light stimulation, affecting brain activity and inducing pleasant emotions (Non-patent document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent application 2023-81899 [Non-patent literature]

[0006] [Non-Patent Document 1] Research report "Thermal stimulation around the eyes and its influence on visual fatigue depending on the location" Chiba University Graduate School of Engineering Laboratory Journal of the Japanese Society of Physiological Anthropology Vol. 23, No. 4, 2018, 11 P143-147 (P146 4 Discussion) DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] 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.

[0008] The present invention aims to provide a combined light-and-heat eyelid stimulator that uses both heat and light stimulation to increase eyelid temperature by promoting blood circulation to the eyelids, while simultaneously inducing a pleasant feeling in the brain, and furthermore, by incorporating a thermometer, to enable the user to confirm changes in eyelid temperature. [Means for solving the problem]

[0009] 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]

[0010] The effects of the photothermal and eyelid anpo device of the present invention are as follows:

[0011] This is shown in the example of [Table 1], "Eyelid temperature increase (°C) due to light-heat and combined light-heat stimulation." In the example, when a combined light-heat stimulation using light and heat was compared with a light-only stimulation and a heat-only stimulation, the combined light-heat stimulation produced the highest eyelid temperature increase, and the increased eyelid temperature was maintained for approximately 30 minutes.

[0011] [Table 1]

[0012] In the examples of the present invention, the light stimulation time was 1 minute, and the heat stimulation time was 5 minutes. When light and heat stimulation were used in combination, the light and heat stimulations were started simultaneously, and the light source was turned off after 1 minute, and the heat source was turned off after 5 minutes. Measurements were taken every 5 minutes for 40 minutes using a thermocouple thermometer. Note that the light stimulation time of 1 minute did not change the effect even if the stimulation time was longer than 1 minute.

[0013] The eyelid light-heat combination anpo device induces a pleasant feeling through thermal stimulation, and allows the user to check changes in eyelid temperature using digital thermo tape. The digital thermo tape can be brought into surface contact with the eyelid, providing stable measurement results. In addition, since it does not require a power source and has a fast response speed, it is suitable for measuring temperature changes.

[0014] To measure eyelid temperature, a photothermal eyelid ampoule with 34°C and 36°C digital thermotapes attached is placed on the eyelid for approximately 30 seconds before and after use, and the results are recorded on a memo card.

[0015] Using [Table 2], you can slide a paper clip onto the memory card on the right of [Table 2] to record the changes before and after use.

[0015] [Table 2] [Brief explanation of the drawings]

[0016] [Figure 1] FIG. 1 is an explanatory diagram of a light and heat combination eyelid anpō device 1 showing an embodiment in which a light eyelid anpō device 4 and a steam hot eye mask 2 are combined. [Figure 2] FIG. 1 is an explanatory diagram of a light-heat combination eyelid anpō device 1 showing an embodiment in which a light-heat eyelid anpō device 4 is incorporated into an electric hot eye mask 3. DETAILED DESCRIPTION OF THE INVENTION

[0017] Figure 1 shows a disposable steam hot eye mask 2 that is heated by steam heat. By covering a conventional eyeglass-type light eyelid ampoule 4 with the steam hot eye mask 2, it can be used as a light and heat combined ampoule 1 for the eyelids.

[0018] Figure 2 shows a conventional light-operated eyelid ampoule 4 with the glasses 5 removed and incorporated into an electric hot eye mask 3, which is also used as a light-operated eyelid ampoule 1.

[0019] The light eyelid ampoule 4 used in Figures 1 and 2 is configured by attaching a substrate 6 equipped with a sponge pad 7 and a far-red LED 8 to glasses 5, and attaching digital thermo tape 9 of 36°C and 34°C to the sponge pad 7. When attaching the light eyelid ampoule 4 to an electric hot eye mask 3, it is attached to the inside of the electric hot eye mask 3 instead of the glasses 5. The sponge pad 7 is also removable, and can be swapped between left and right. Power is supplied from an AC adapter (not shown) or the like.

[0020] The procedure for use is explained below. Before placing the light-heat and ampoule device 1 for eyelids (Fig. 1 and Fig. 2) on the eyelids, cover the light-heat and ampoule device 1 with food wrap film, which is safe, hygienic, and adheres well to the skin, to prevent the digital thermo tape 6 from coming into direct contact with the skin.

[0021] The procedure for use is the same as for the eyelid light mask 4, but the usage time can be set by a timer or a separate buzzer. In the case of [Figure 1], remove the steam hot eye mask 2 from your eyelids after 5 minutes, and in the case of [Figure 2], turn off the electric hot eye mask 3 after 5 minutes.
