Description

  The present invention relates to a soft contact lens removing device for removing a soft contact lens attached to an eye.

  In recent years, the wearing population of contact lenses has increased from 15 million to 18 million, and it is estimated that one out of every eight people wears contact lenses. With the rapid spread of TVs, PCs, games, e-books, smartphones, etc., our young people's vision is on the decline. In addition, although the eyesight has fallen, it has become natural that boys who play sports choose contacts instead of glasses and start using young contact lenses. Incorrect knowledge, easy hurdles, filthy handling, and accompanying this, eye disorders due to contact lenses are rapidly increasing, and it is estimated that 10 or more of the contact lens wearers have one or more eye problems. Yes. (It is just a statistical report, and the obstacle is presumed to be the tip of the iceberg because of its progressive nature.)

  In addition, according to a survey on contact lens wearing conditions conducted for elementary and junior high and high school students nationwide, the number of elementary and junior high and high school students wearing significantly increased in all grades. One in four high school students wears contact lenses, and the number of elementary and junior high school students is increasing. In recent years, the number of wearers of color contact lenses with a sense of fashion is increasing rapidly, mainly among elementary, middle and high school students. In major job hunting activities in urban areas, there are reports that almost 100% of women use contact or color contact lenses for beauty “eye power”.

  In this way, contact lenses, whose wearers are becoming younger, are highly medical devices, but many of them are available at drugstores without a prescription at a low price. doing. For this reason, the hurdle of acquisition and mounting is low. Inevitably, there are increasing cases of wearing without knowledge. In addition, there is no mention of eye damage in the instruction manual of the product, and it is said to "ophthalmologist if there is an abnormality", and there is almost no risk of easy usage or wrong eye warnings. It is. In some cases, there is no detailed explanation of how to attach and remove. In addition, regular ophthalmic visits are required once every three months, but the current situation is that the system allows easy access to contacts without seeing them. It is in a state of a product that feels comfortable wearing eyelashes.

  However, recently, many eye problems associated with wearing contact lenses have been reported and attracted attention. Many current ophthalmology emergency outpatients are due to contact problems, especially those that cannot be removed, and require treatment that they have entered the back of the eyeball while messing around with their fingers. It has become a thing. Inadequate hygiene management, contamination with Pseudomonas aeruginosa, etc., leaving you busy and troublesome, enduring with eye drops, and if you continue to wear and become serious, you will see a university hospital. Examples of ocular disorders include punctate superficial keratopathy, corneal endothelial dysfunction, corneal infiltration / corneal ulcer, giant papillary conjunctivitis, corneal neovascularization, corneal epithelial erosion, corneal edema, and the like. In particular, corneal endothelial dysfunction, which occurs reliably, is familiar and progressive, is a problem. This is because the visual acuity is significantly reduced, and eventually it causes blindness.

  For example, failures as shown in FIGS. 9 and 10 have been reported. In FIG. 9, the dotted sites indicated by arrows represent corneal disorders. In FIG. 10, corneal damage is seen over a wide area.

  A corneal endothelial disorder is generally caused by a lack of oxygen supply to the cornea. However, in many cases, the cells are physically damaged by continuous friction against the eye, particularly stimulation by direct pressure that squeezes out when the contact lens is removed.

  Here, corneal endothelial cells will be described. Corneal endothelial cells are the innermost cells of the black eye that are responsible for the respiration and metabolism of the black eye and maintain the transparency and visual acuity of the black eye. It is an irreversible cell that does not regenerate once it is reduced. When corneal endothelial cells continue to be damaged, they gradually decrease, failing to maintain the transparency of black eyes, edematous, cloudy, and painful.

  As a treatment, there is only the worst and ultimately corneal transplantation, but the supply of cornea is small, and even if corneal transplantation is done, the establishment rate is very low, and it will not be established even after 10 treatments. Although not done, it eventually leads to blindness. There is a high possibility that the number of corneal endothelial cells, which are usually 2500 to 3000 per 1 mm 2, decreases to 2000 or less after 10 years of contact lens wear (entering the category of long-term users in 10 years). If the number is less than 1500 per 1 mm 2, LASIK cannot be performed, and if the number is less than 1000, surgery such as cataract cannot be performed in the future.

More specifically, there are impaired corneal endothelial cells as shown in FIG. It can be seen that the shape of the cell is destroyed. In addition, allergic conjunctivitis, corneal wounds, and corneal ulcers as shown in FIG. 12 have been reported. As shown in the lower part of FIG. 12, the cell density is 3,448 / mm ² when no contact lens is used, whereas the cell density is 708 / mm ² when the contact lens is worn for 20 years.

As described above, there is a concern that if the population that starts wearing contact lenses at an early stage without knowledge due to the aging of the population increases, it will become a young blindness society with a large population that will be blind in the 40s. Many people who live outside work, such as full-time housewives, do not use contacts on a regular basis. Blindness is equivalent to "Disabled Class 1" and can lead to a loss of working population. It also increases the social security burden. It can be a great loss of national interest.
Therefore, in order to alleviate eye damage from a young age and protect the eyes of children and young people, I would like to recommend the device of the present invention to the habitual use especially from the early age, especially from the beginning of using contact lenses.

  As an instrument for removing a contact lens, for example, a contact lens mounting aid of Patent Document 1 is known. The contact lens mounting aid of Patent Document 1 has a bifurcated upper end, and is configured to remove the contact lens by pinching the contact lens on the eyeball.

Japanese Patent No. 5208320

However, in the configuration of Patent Document 1 described above, the pinch with fingers is pinched toward the center of the black eye with a tweezer-like instrument, but it is removed by hand in order to give a stimulus that oozes out to the eyes. Same as the case. In addition, there was a catch when pinching, and it was painful. Use is skillful, relatively complex and unsuitable for children. Even troublesome teens and drunk office workers feel difficult. At present, there is no detailed ophthalmic data on how much eye irritation causes damage to the eyeball, and it is emphasized that there is only oxygen deficiency as an adverse effect of contact lenses, Stimulation is also thought to have a major effect on eye damage.
The aforementioned patent can also be thought of as a specialized hygiene that does not use fingers directly. The cornea has no blood vessels and is a special organ that touches the surface of the human body. For example, the pain is completely different when you apply pressure on your fingers with your fingers and when you apply pressure on your eyes with your fingers even after you close the eyelids.
The fingers are not engorged by physical pressure, but the eyeball is engorged easily.

Therefore, the present invention provides a soft contact lens removing device capable of removing the soft contact lens so as not to give a stimulus to the eyes and a method of using the soft contact lens removing device. It is an object. By not squeezing out, chronic physical irritation is reduced.
The present invention is a device in which a small balloon is applied to the contact wearing surface, the contact is adsorbed together with tears on the surface by negative air pressure, and is easily removed.

  In order to achieve the above object, a soft contact lens removing device of the present invention is a soft contact lens removing device for removing a soft contact lens attached to an eye, and a suction cup portion for adsorbing the soft contact lens And it has a suction cup part which has a small hole which penetrates, and a pump part which takes air in and out through the small hole.

  Further, the method of using the soft contact lens removing device of the present invention includes the step of discharging the air in the pump part from the small hole by squeezing the pump part formed in a spherical shell shape with a finger. A step of bringing the sucker portion into contact with the soft contact lens attached to the eye, and loosening a hand grip and returning the crushed pump portion to a spherical shell shape, whereby the soft contact lens is moved by the sucker portion. Adsorbing, and separating the soft contact lens removal device from the eye while adsorbing the soft contact lens.

  As described above, the soft contact lens removing device of the present invention is a soft contact lens removing device for removing the soft contact lens mounted on the eye, and is a suction cup portion that adsorbs the soft contact lens, and is penetrating. And a suction part having a small hole and a pump part for taking air in and out through the small hole. For this reason, a soft contact lens can be removed so that the irritation | stimulation which oozes out to an eye may not be given.

  Further, the method of using the soft contact lens removal device of the present invention includes a step of discharging air in the pump part from the small hole, a step of bringing the suction cup part into contact with the soft contact lens, and a pump part in a spherical shell shape. A step of adsorbing the soft contact lens by the sucker part by returning and a step of separating the soft contact lens removal device from the eye while adsorbing the soft contact lens. For this reason, a soft contact lens can be removed so that the irritation | stimulation which oozes out to an eye may not be given.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Structure of eye and soft contact lens)
First, a state where the soft contact lens 6 is attached to the eye 5 will be described with reference to FIG.

  The eye 5 includes a cornea 51, an anterior chamber 52, a crystalline lens 53, a vitreous body 54, a retina 55, and an optic nerve 56. When looking at things, the light that enters the eyes is adjusted by the iris, refracted by the lens 53 that adjusts the focus, passes through the vitreous body 54, and focuses on the macula of the retina 55. The light is transmitted to the brain as a signal through the optic nerve 56. The shape of the cornea 51 is not an accurate spherical surface, but is generally an aspherical surface with a curvature that increases from the center to the periphery.

  The soft contact lens 6 is a flexible contact lens made of a synthetic polymer compound containing water. The moisture content varies depending on the material, but is about 55 to 70%.

  The soft contact lens 6 is formed in a dish shape or a spherical shape as a whole so as to match the shape of the front surface of the cornea 51. The shape of the soft contact lens 6 is generally defined by a base curve that is the radius of curvature of the rear surface of the lens, the lens diameter of the entire lens including the peripheral portion, and the center thickness that is the thickness of the center portion of the lens.

  For example, the lens diameter is about 13 to 14.5 mm, which is larger than the cornea 51 and covers the conjunctiva portion. The base curve is generally 8.5 to 8.6 mm, and the center thickness is generally 0.070 to 0.085 mm (in the case of −3.00 D). The base curve and diameter of each company's products are almost unchanged.

The contact lens is attached to the eye 5 by the surface tension of tears. Therefore, it can be said that the soft contact lens has a larger surface tension than the hard contact lens and has a larger surface tension than the hard contact lens. In the mounted state, the soft contact lens 6 is deformed according to the surface shape of the cornea 51.
(Configuration of the removal device)

  Next, the overall configuration of the soft contact lens removing device 1 of the present invention will be described with reference to FIG. As shown in FIG. 2, the soft contact lens removal device 1 of the present invention is a soft contact lens removal device 1 for removing the soft contact lens 6 attached to the eye 5, and adsorbs the soft contact lens 6. The suction cup section 2 includes a suction cup section 2 having a small hole 22 that passes therethrough, and a pump section 3 that draws air in and out through the small hole 22.

  The suction cup portion 2 is formed of a synthetic resin, and includes a morning glory portion 21 that expands in a trumpet shape and a small hole 22 that opens the bottom of the morning glory portion 21. The suction cup portion 2 is bonded to the pump portion 3 around the small hole 22 or is formed integrally with the pump portion 3.

  The vicinity of the outer edge of the morning glory 21 has a concave surface shape that follows the convex front shape of the soft contact lens 6. The outer diameter of the outer edge of the morning glory portion 21 is slightly smaller than the outer diameter of the soft contact lens 6.

  The small hole 22 communicates with the inside of the spherical shell-shaped pump unit 3. The diameter (inner diameter) of the small hole 22 is set to such a size that the soft contact lens 6 does not enter the pump portion 3 when the soft contact lens 6 is adsorbed.

  In addition, the part which contacts the soft contact lens 6 of the suction cup part 2 does not need to be formed in a trumpet shape, and has a dish-like shape having a concave surface shape along the convex front shape of the soft contact lens 6 ( It is also possible to form an aspherical surface but close to a spherical surface. In this case, the small hole 22 can be formed as a through hole provided in the bottom portion (substantially center) of the dish.

  Speaking about the material in detail, the sucker part 2 is a gel-like silicon polymer or gel that has self-adhesiveness (without using a solvent and the material itself has adhesiveness) with water adhering to the surface. It is formed of a super soft urethane rubber or the like. It is preferable that the adhesive force with respect to the soft contact lens 6 exhibited by the suction cup portion 2 is equal to or higher than the adhesive force (due to surface tension) between the soft contact lens 6 and the eye 5.

  The pump part 3 is made of a synthetic resin having flexibility, a spherical shell part 31 formed in a hollow spherical shape (spherical shell shape), a communication part 32 that is a hole provided in the spherical shell part 31, It has.

  The spherical shell portion 31 is formed of natural rubber, urethane rubber, silicon rubber, synthetic rubber or the like having a flexibility that can be crushed by a finger. At the same time, the spherical shell portion 31 tries to return to its original shape when the force grasped by the fingers is loosened. In addition, the pump part 3 (spherical shell part 31) can also be integrally molded with the same material as the suction cup part 2. The outer diameter of the spherical shell portion 31 is considered to be a size that can be easily grasped by hand, for example, about 3 cm in diameter.

  The communication part 32 is a hole provided in the spherical shell part 31 and communicates with the small hole 22 of the suction cup part 2. That is, the internal space of the spherical shell portion 31 is connected to the external space only through the small holes 22. Therefore, when the spherical shell portion 31 is crushed with a finger, the internal volume is reduced, so that the internal air is discharged to the outside through the small hole 22. When the hand grip is loosened, the internal volume increases, so that external air is sucked into the inside through the small hole 22. At this time, if there is an object that closes the suction cup portion 2 (small hole 22), the internal air pressure becomes lower than the external air pressure, so that the object is sucked to the suction cup portion 2.

(How to use the removal device)
Next, a method of using the soft contact lens removing device 1 of the present embodiment will be described with reference to FIGS. 4 to 7, for convenience of explanation, the soft contact lens removing device 1 and the eye 5 are drawn as a cross-sectional view, and only the hand is drawn as a plan view.

  First, the step of discharging air will be described with reference to FIG. In the step of discharging air, the air in the pump unit 3 is discharged from the small holes 22 by squeezing the pump unit 3 formed in a spherical shell shape with fingers. That is, before the suction cup 2 is brought into contact with the eye 5 in advance, air is discharged by crushing the spherical shell 31 with a finger.

  Next, the step of bringing the suction cup portion 2 into contact will be described with reference to FIG. In the step of bringing the sucker unit 2 into contact, the sucker unit 2 is brought into contact with the soft contact lens 6 attached to the eye 5. That is, the hand holding the soft contact lens removing device 1 while squeezing it is slowly brought closer to the eye 5 with the suction cup 2 facing the eye 5, and the suction cup 2 is brought into contact with the soft contact lens 6.

  At this time, since the pump part 3 is formed in a spherical shell shape, it is easy to change the position of the suction cup part 2 relative to the pump part 3. Therefore, even if the suction cup part 2 is too close to the soft contact lens 6, the suction cup part 2 moves so as to sink into the pump part 3, so that the drag on the eye 5 is relaxed. In addition, since there is a constricted part (reduced diameter part) between the suction cup part 2 and the pump part 3, even if the suction cup part 2 is tilted and contacts the soft contact lens 6, the suction cup part 2 follows the tilt. You can move as you do.

  Next, the step of adsorbing the soft contact lens 6 will be described with reference to FIG. In the step of adsorbing the soft contact lens 6, the soft contact lens 6 is adsorbed by the suction cup part 2 by loosening the grip of the fingers and returning the crushed pump part 3 to a spherical shell shape.

  That is, when the suction part 2 is in contact with the soft contact lens 6 when the pump part 3 tries to return to the original shape, the small hole 22 is closed, and the atmospheric pressure in the pump part 3 decreases. Then, the soft contact lens 6 is pushed from the outside toward the suction cup part 2 by the atmospheric pressure, and is thus attracted to the suction cup part 2.

  In addition, although the surface of the soft contact lens 6 is wet with tears, since the tears can be sucked into the pump unit 3 through the small holes 22, the soft contact lens 6 is reliably adsorbed by the sucker unit 2. .

  Thus, in more detail, the step of sucking includes the step of sucking tears and the step of sucking the soft contact lens 6.

  Furthermore, when the hand grip is loosened, the suction cup 2 moves by a small amount in the direction of the pump 3 as the pump 3 returns to its original shape. By this movement, a step away from the eye 5 described later is promoted.

  Next, the step of separating the soft contact lens removal instrument 1 from the eye 5 will be described with reference to FIG. In the step of separating the soft contact lens removal device 1 from the eye 5, the soft contact lens removal device 1 is separated from the eye while the soft contact lens 6 is adsorbed. That is, the hand holding the soft contact lens removing device 1 is slowly moved away from the eye 5 with the suction cup 2 facing the eye 5, and the soft contact lens 6 is removed from the eye 5.

  At this time, the soft contact lens 6 is in a state of being adhered to the suction cup portion 2 and is separated from the eye 5 while maintaining the shape along the suction cup portion 2. In other words, the soft contact lens 6 is removed so that the eye 5 is not stimulated to ooze.

  Then, the soft contact lens 6 adsorbed by the suction cup part 2 can be removed from the suction cup part 2 by crushing the pump part 3 again. The removal device 1 may be washed with water, drained and dried naturally. The removed soft contact lens 6 is washed as usual and stored in a washing case (cleaning liquid).

(effect)
Next, the effect which the soft contact lens removal instrument 1 of a present Example show | plays is enumerated and demonstrated.

  (1) The soft contact lens removing device 1 according to the present embodiment is a soft contact lens removing device 1 for removing the soft contact lens 6 attached to the eye 5, and a suction cup for adsorbing the soft contact lens 6. The suction cup part 2 which has the small hole 22 which is the part 2 and penetrates, and the pump part 3 which draws air in and out through the small hole 22 are provided. For this reason, the soft contact lens 6 can be removed so as not to give the eye 5 a stimulus to ooze out.

  (2) The pump part 3 includes a spherical shell part 31 made of a flexible material. Since the inside of the spherical shell part 31 communicates with the small hole 22, the pump part 3 enters the pump part 3 through the small hole 22. Since the tears can be sucked, the soft contact lens 6 is reliably adsorbed by the suction cup 2.

  From this point of view, it is preferable that the small hole 22 has a small diameter to such an extent that it can suck in tears. That is, if the diameter of the small hole 22 is too large, there is no pressure difference between the inner surface of the suction cup portion 2 and the small hole 22, so that it is difficult to suck tears, so the diameter of the small hole 22 is reduced.

  Moreover, when the pump part 3 is formed in a spherical shape as a whole, when the soft contact lens removing device 1 is brought close to the eye 5, fear can be relieved. That is, when a rod-like object is brought closer to the eye 5, a feeling of fear of being struck by the eye 5 is felt, but if it is spherical, there is no possibility of being struck by the eye 5, so that the fear can be relieved. Children can also be viewed as fun.

  (3) By further providing a cap (not shown) for covering the suction cup part 2, the suction cup part 2 can be used in a sanitary manner, and the soft contact lens removing device 1 can be easily carried in a pocket or the like. It is also possible to do.

  (4) The soft contact lens removal instrument of the present embodiment is a method of using any of the soft contact lens removal instruments 1 described above, and grips the pump part 3 formed in a spherical shell shape with fingers. The step of discharging the air in the pump unit 3 from the small hole 22 by crushing, the step of bringing the suction cup unit 2 into contact with the soft contact lens 6 attached to the eye 5, and the pump crushed by loosening the grip of the fingers A step of adsorbing the soft contact lens 6 by the suction cup portion 2 by returning the portion 3 to a spherical shell shape, and a step of separating the soft contact lens removal device 1 from the eye 5 while adsorbing the soft contact lens 6; It has. For this reason, the soft contact lens 6 can be removed so as not to give the eye 5 a stimulus to ooze out.

  (5) The step of adsorbing the soft contact lens 6 includes the step of sucking tears into the pump unit 3 and the step of adsorbing the soft contact lens 6 to the surface of the suction cup unit 2. As a result, the soft contact lens 6 that is wet with tears is adsorbed.

  Hereinafter, with reference to FIG. 8, a soft contact lens removal tool 1 </ b> A that is smaller than the first embodiment will be described. In addition, the description which attaches | subjects the same code | symbol about the description of the same thru | or equivalent part as the content demonstrated in Example 1, and demonstrates.

  First, the configuration will be described. The soft contact lens removal tool 1A of the present embodiment includes a suction cup portion 2 and a pump portion 3 as in the first embodiment.

  The suction cup portion 2 is formed of a synthetic resin, and includes a morning glory portion 21 that expands in a trumpet shape and a small hole 22 that opens the bottom of the morning glory portion 21. The suction cup portion 2 is bonded to the pump portion 3 around the small hole 22 or is formed integrally with the pump portion 3.

  The pump part 3 is made of a synthetic resin having flexibility, a spherical shell part 31 formed in a hollow spherical shape (spherical shell shape), a communication part 32 that is a hole provided in the spherical shell part 31, It has. In addition, the pump part 3 (spherical shell part 31) can also be integrally molded with the same material as the suction cup part 2.

  And the pump part 3 (spherical shell part 31) of the soft contact lens removal instrument 1A of the present embodiment is compared with the pump part 3 (spherical shell part 31) of the soft contact lens removal instrument 1 of Example 1, It is formed to be smaller. In other words, the pump part 3 (spherical shell part 31) of the soft contact lens removal instrument 1 of Example 1 had an outer diameter substantially the same as the outer diameter W2 of the eye 5, but The pump part 3 (spherical shell part 31) of the soft contact lens removal instrument 1A has an outer diameter W1 that is smaller than the outer diameter W2 of the eye 5.

  More specifically, the outer diameter of the pump part 3 (spherical shell part 31) of the soft contact lens removing device 1A of the present embodiment is preferably in the range of 1 cm to 2 cm, more preferably about 1.5 cm. is there. That is, it is preferable that the outer diameter of the pump part 3 (spherical shell part 31) of the soft contact lens removing device 1A is substantially the same as the outer diameter of the soft contact lens 6 or the outer diameter of the cornea 51.

  Thus, since the size of the soft contact lens removal tool 1A of the present embodiment is close to the size of the cornea 51 and the soft contact lens 6, the feeling of fear decreases when the eye 5 is brought close. Further, since the soft contact lens removal tool 1A itself is small, it is easy to aim at the soft contact lens 6. Furthermore, it is easy to carry and store the soft contact lens removal instrument 1A when not in use.

  In addition, since it is as substantially the same as Example 1 about another structure and an effect, description is abbreviate | omitted.

  The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to the present invention. included.

  For example, in the embodiment, the case where the suction cup part 2 is bonded to the pump part 3 has been described. However, the present invention is not limited to this, and the suction cup part can be configured to be replaceable.

Although not described in the embodiment, a pattern or an illustration can be drawn on the surface (outer surface) of the spherical shell portion 31. It can be a familiar medical device that is more familiar and can be designed with beautiful colors and patterns, with names, or with Swarovski stones. Because there is no medical concern for the spherical shell, enjoy illustrations of animals such as cats, dogs and bears, wearing cat ears, and drawing trendy characters so that children can enjoy and enjoy easy to use Both are possible.
Moreover, in use, it is practical and simple.
