Description

Description Technical field of eye heater

The present invention is directed to an ophthalmic function improving heater for improving the eye function and improving the eye function. Landscape technology

Recently, the importance of visual information has been increasing due to the spread of display devices, and the cold weather has led to a stable life throughout the year. The number of people experiencing eye illness and eye strain due to such changes in life swelling is increasing, and the demand for treatments to alleviate and prevent fatigue is increasing.

In particular, i ^ D of dry eye, which can not maintain the normal condition of the eye surface with a little tears, is remarkable, but as a treatment for this dry eye, it is necessary to prevent clogging of the meibomian gland that produces oil on the surface of the eye. Heat treatment using steamed evening ol has been performed.

The Meibomian glands are small glands around the eyelids, and the oil produced there covers the entire tear film that forms on the surface of the eyes and prevents water from evaporating. Therefore, for example, if this gland is clogged, the tears will build up in the oil layer, causing tears to be easily emitted, causing dry eye. In order to promote the secretion of the meibomian glands, only the meibomian glands need to be warmed.

According to the heat treatment by steaming, the warming of the eyelids

By being solidified It dissolves the secretions of the meibomian glands and helps to keep the tear film normal.

In addition, a thermal treatment device called an anthropic device was also used in ophthalmology. This is a dryer-type device that uses infrared radiation. It is resistant to near-infrared rays by holding it with one hand and using it while holding it. Although this method was used to convert styes and others, it was made possible by the popularization of eye drops for substance f. In addition, it was pointed out that the effect of this method was too small because of the low rise of the bean paste.

On the other hand, infrared heaters for living bodies such as shoulders and hips are still commonly used today, and the main types of shellfish are infrared heaters of the type, infrared heaters of the ceramic type, and infrared rays. There are a heater and an infrared heater of the LED diode type.The one that has been used in ophthalmology from the thread is a red t-ray treatment device of the required type.

However, in the treatment of rat fever with Yuru Oru, the heat

It took a long time to reach the meibomian gland located 4 mm inside, and the heat radiated to the outside was large and the temperature jg ± rise was unstable and ineffective.赤外線 Infrared heaters used by ず only reach a few millimeters from the skin surface ^^, and it is thought that heat gradually penetrates into the skin by transduction. For this reason, there was a problem that it took a long time and the surface of the eyelid became too hot.

Also, the previous products we have been selling are: cM, which must be hand-held and not easy to use.

Therefore, the present invention is intended to provide a heater for a good L and B gizzard, which is not too hot, has a good time and is safe, and is good for use. It is.

In order to achieve the above object, the ophthalmic function-improving heater of the present invention includes a cover having a plurality of near-infrared light emitting diodes capable of increasing the temperature of the eyelid and the eye on an inner surface thereof.装着にに IS IS 装着 IS 装着装着 IS 装着 IS 構成装着構成構成構成構成構成構成 IS IS IS IS IS IS 構成構成 IS IS 構成 IS IS IS IS IS 構成It can be used as a heat treatment device for improving eye function.

It is also possible to separate the armor into two parts and to use the self-attaching hand! According to this, the position of each patient's eyes and near infrared rays can always be used in correspondence with each other, and it is a cross-over.

In addition, it is possible to have a hook for the B, and the ilS mounting means can be a frame for the B profession. This allows the self-eye function to be improved while using the fins. And the ability to easily adjust to the eye position.

In addition, there is a hole in the hole corresponding to the eye, and a near-infrared diode is placed around the periphery of the hole. According to this, it can be used with the eyes open.

In addition, the peak wavelength is near 850 nm to 950 11111, which is near red and blue. Use of a diode is effective for the function of the surface of the eye, which is 3 to 4 mm deep from the surface. Able to warm related tissues to the chest.

Near-infrared LEDs have low light energy compared to laser light, and have sufficient penetration into i¾f by decomposing a constant amount of light. Xie is small. In addition, when the near-infrared ray is used as the specific wavelength, compared to the conventional case where long-infrared rays are used, the light received by the living body is deeper and more effective as a heater. Be a sharp Ka is known. This is because the infrared light in the near-infrared region has a negative effect on light to the living body.

For example, using a peak wavelength of 94 O nm, the depth to reach J¾f is said to be about 6 mm, and if heat is further recited, it is thought that it will be pushed to 20 mm away.

For this reason, the LED therapy device penetrates deep into the thermoelectric body in a short time, and the surface of the J¾f is not excessively covered as in the case of conventional infrared rays. It can be said that it can be used with confidence. Brief description of

FIG. 1 shows a conceptual diagram of an ophthalmic function improving heater according to one embodiment of the present invention. FIG. 2 shows a cross-sectional view of the cover of the ophthalmic function improving heater which is the same embodiment as FIG. 1 of the present invention. FIG. ³ is a view showing an ophthalmic function improving heater according to another embodiment of the present invention, wherein (a) shows a partial plan view and (b) shows a front view of a cover thereof. BEST MODE FOR CARRYING OUT THE INVENTION

The eye function improving device 1 is composed of two covers L ゝ 7 in which a plurality of near infrared rays diodes 5 are arranged in the recess 3 and a lead wire 9 from each of the ilSH ヽ, and a socket 11 is connected. Power adapter — (Fig. ^:). A magic tape 13 (see FIG. 2) is occupied on the surface opposite to the concave portion 3, and is detachably attached to the mounting veg 15 provided with the magic tape. The knitting 7 here is made of plastic of about 7 × 5 centimeters, and as shown in the cross-sectional view of FIG. 2, the recess 3 has 16 near red light emitting diodes 5 and 3 Red light emitting diode 6 strengths are self-built. For example, in addition to plastic, a material that is capable of being produced with rubber, for example, is a non-heat-transfer power wheel. In addition, the iisa infrared diode 5 varies depending on the number per unit 碰, and the more the number, the more energy can be used to increase the thermal effect, but it is used for eye use. It is easy to set the size and number to ^^.

As described above, a total of 19 miaa infrared diodes 5 and ji self-red ^: diodes 6 are installed on the substrate 19 inside the cover 7, and the lead wire 9 is led out from one end of the cover 7. Have been. Of the wavelengths in the near-infrared region of about 760 nm to 250 nm, the wavelength that is particularly easy for the skin is the near-infrared ray of 800 nm to 1200 nm. (3) As a good heater, a near infrared ray having a peak wavelength of 850 nm to 9500 nm is used. In a difficult example, there are 16 near-infrared light emitting diodes having a peak wavelength of 940 nm (hereinafter, referred to as 940 nm), and a peak wavelength of 660 nm (hereinafter, 6). 60 nm) Three red diodes are used. Since the near-infrared light of 940 nm is colorless, it is easy to determine the power ON / OFF by using three red ¾ ^ diodes of 660 nm. The red light emitting diode 6 may be used as long as it does not feel dazzling at the time of use and does not impair the effect of near-infrared rays. Also good ヽ. Also, if the red diode 6 is provided only on the outside of the cover L and 7, the patient will not feel dazzling when using.

鼠 When using the self-eye function improving rat fever 1, attach a cover 7 to the magic tape section 17 of the self-attached belt according to the position of the patient's eyes, The wearing belt 15 is used by being wrapped around the head. The belt 15 has a magic tape section 17 "^" or on the front, It is made of stretchable material, so adjust the tightening ^ 好み according to your preference. Also, the mounting belt 15 can be of an eye mask type, and this ^^ is provided with a magic tape [U 7] to attach a 7 inside the eye mask. After the installation of the Zeniyo Kiyo Zenyo Warmer 1, plug the power adapter into a household power source and use it for about 5 to 15 minutes. At this time, if the power is turned on / off by installing a switch near the socket 11 or the socket, it can be easily operated at hand. If a switch is provided on each of the covers 7, it is possible to erase only one of them in the middle as necessary. In addition, the evening image can be attached to the ^^ of the heater 1 for improving the self-eye function. Since the switch becomes 0 FF, it is possible to prevent irradiation more than '. By providing a buzzer or the like to notify the end of use, it will be easier to know that the use is completed.

Since the cover 7 is fixed to the head with the wearing belt, it is not supported by a hand or the like, and can be used while sitting on a computer. Of course, it is possible to move within the range of the lead wire 9. When used, the amount of light slightly increases, but there is no arrangement of near infrared rays or heat, so it is safe.

Using the Satsumi eye function improvement heater, the light is turned from the skin surface to a depth of 6 mm to warm. Therefore, the skin surface is warmed only by its guidance, so it is safe to use, for example, for a longer period of time than normal, since it does not become hot enough to cause burns or other dangers. is there. In addition, even after removing the self-eye function improving heater, the conventional force from the skin surface α temperature]: I do. For example, in dry eye treatment, the meibomian gland is supposed to be 力 strength ^, skin 、 strength, etc., to a depth of about 10 mm. Therefore, if the wavelength in the near infrared region is used, thermal treatment suitable for the power of the meibomian gland can be performed. Also, in the treatment of dry eye, it can improve the blood flow not only in the meibomian glands but also in the vicinity of the meibomian glands and around the eyes. Giving eyes Iffi labor is eased. Further, the heater for improving ocular function according to the present invention can reduce the power consumption by requesting infrared rays, so that Kasumihara can be made portable as a battery. Infrared diode used L を ta Heater for improving the function of one's own eyes 1 to 5ino 1 5 eyes Apologize for the fact that there is no view to eye safety.

For example, with the center of the wavelength at 950 nm, and using about 2.3 light emitting diodes / cnf that emit 93% or more of infrared light in the area of 950 ± 50 nm, a unit per unit is used. However, this near-infrared radiant energy is 2 to 4 times the energies of radiant energy in the same wavelength range that the skin receives from the sun for the welfare. However, 5 minutes is equivalent to 10 to 20 minutes of sunbathing, and it is not uncommon for people to be exposed to sunlight for more than 1 B temple a day with their eyelids open even in daily life Given that, there is no view to eye safety. In addition, the total amount of near-infrared energy that can easily penetrate into the sun can be reduced by using the jl-self-diode to heat the eye-function-improving heater and the sun. The amount of radiant energy of the sun corresponds to about the same amount to half of the amount of energy at the same wavelength of the sun (here, ^^ of 800 to 120 O nm).

The result of using the heater for improving ocular function which is the first example of the present invention described above is shown.

Dry eye patients with harm to my volume 2 Improved eye function according to the present invention in 2 patients In the morning and evening, I was asked to use the heater twice, 5 minutes each, and observed improvement in my subjective and objective findings.

The status before use had a score of 7.5 ± 1.8, but after a two-week use, decreased significantly to 4.8 ± 2.8. The score means a sharp score judged based on the user's self-symptoms, with 9 points being the most straight and 1 being the best value.

The tear break time (BUT) before use was 4.1 ± 2.5 seconds, but improved to 10.4 ± 4.9 seconds two weeks after use.

Tear breakup time (BUT) is a measure of how long tears begin to cover the surface of the eye. To do this, have the patient apply a fluorescein dye and look straight ahead with the eyes open. Then, the surface of the eyes gradually dries, and the flarescein disappears or disappears. This time until the appearance of fluorescein is called tear film break up time (BUT).

The number of blinks measured at the same time was 28.5 ± 11.9 times / min before gluing, but the force was reduced to 22.4 ± 11.2 times / min, indicating that the treatment effect was stubborn.

Table 1 shows a table of the measurement results obtained when the anchorage device and the steamed oar used in Table 1 and the heater for improving ocular function according to the present invention were used by the same officer.
