Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a cleaning device for contact lenses such as soft contact lenses.

[Prior art and its problems]

As for soft contact lenses, at present, soft contact lenses are washed daily with a so-called soft cleaner, a soft contact lens cleaning solution, and after the above-mentioned washing, rinsed with tap water and then rinsed. It is required that the lenses be stored in soft contact lens stock solution and sterilized by boiling. However, as is well known, soft contact lenses have the property of swelling from the surface of the material. Therefore, when proteins or lipids, etc., adhere to the surface of soft contact lenses, unlike the case of hard contact lenses, this stain becomes It has been pointed out that it cannot be removed easily. That is, when the contact lens is contaminated with protein and lipid components attached to the contact lens, the degree of removal of the stain is completely different depending on whether the contact lens is a hard contact lens or a soft contact lens, It is said that in the case of soft contact lenses, it is extremely difficult to remove stains due to proteins and the like as compared with the case of hard contact lenses. Therefore, conventionally, for protein stains attached to the surface of a soft contact lens, a proteolytic enzyme has been added to a soft contact lens cleaning solution, and the protein attached to the surface of the soft contact lens by the action of the proteolytic enzyme. However, even if such a soft contact lens cleaning solution is used, it is not one that can cleanly clean the soft contact lens stains even if such a soft contact lens cleaning solution is used. There are drawbacks.

FIG. 1 is a schematic perspective view of the whole, FIG. 2 is a sectional view, and FIG. b) is a schematic perspective view of a main part. In each figure, 1 is a soft contact lens made of an appropriate swelling material such as 2-HEMA. 2 is a holder corresponding to the shape of the outer surface of the swollen soft contact lens 1, for example, a holder having a concave portion 2a having a radius of curvature of 7 to 11 mm, 3 is corresponding to the shape of the inner surface of the soft contact lens 1. , For example, the radius of curvature is 7 ~
This is a holder having a convex surface portion 3a of 11 mm, and the swollen soft contact lens 1 is arranged in the space between the concave surface portion 2a and the convex surface portion 3a of these holders 2, 3. Further, in the state where the swollen soft contact lens 1 is arranged in the space between the concave surface 2a of the holder 2 and the convex surface 3a of the holder 3, the soft contact lens composed of the holder 2 and the holder 3 A holder so that there is a gap through which liquid can flow in and out between the installation space of 1 and the outside, and further, the surface of the swollen soft contact lens 1 and the concave surface portion 2a and the convex surface portion 3a are not pressure-bonded. 2,
Make up three. The holders 2 and 3 are appropriately molded using polyethylene, polypropylene, silicon resin, acrylic resin, polysulfin, polycarbonate, polyester, fluorine resin, etc., which can withstand heating at about 80 to 100 ° C., for example. It is configured using means. Reference numeral 4 is a fine abrasive provided on the surfaces of the concave surface portion 2a and the convex surface portion 3a, for example, having a particle size (diameter) of 1 to 5 μm. Incidentally, as means for providing the abrasive 4 on the surfaces of the concave surface 2a and the convex surface 3a, a binder such as an abrasive, a vinyl chloride resin, an acrylic resin, or other appropriate bonding resin,
And a paint consisting of an appropriate organic solvent such as toluene
2A and the surface of the convex portion 3a may be applied to a predetermined thickness, that is, a thickness smaller than the particle diameter of the abrasive 4, and dried to form a coating layer containing the abrasive 4, or a vacuum vapor deposition method or sputtering. A method such as a law may be used. Then, as the abrasive used, for example, silica, alumina, boron carbide, silicon carbide, talc or the like can be used. Since attachment of proteins and the like caused by wearing the soft contact lens 1 on the eye is mainly on the outer surface side of the soft contact lens 1, the abrasive 4 is provided only on the concave surface 2a side of the holder 2, Convex part 3a of holder 3
It may not be provided on the side. A bar-shaped magnet 5 is embedded in the lower portion of the holder 2. Reference numeral 6 denotes a holder storage cup in which two chambers are constituted by an internal partition wall. As shown in FIG. 2, the soft contact lens 1 held and held by the holders 2 and 3 is stored in each chamber. It has become so. Incidentally, 7 is a lid of the holder storing cup 6. Also, although not shown in the drawings, each chamber of the storage cup 6
A pipe communicating with a wash water tank 8 for rinsing, a soft contact lens preservative solution tank 9 and a drain tank (not shown) is provided. 10 is a motor, 11 is a motor shaft, 12 is a driving force transmission means provided on the motor shaft 11, 13 is a force from the driving force transmission means 12 so as to rotate about an imaginary line indicated by an alternate long and short dash line It is a magnet provided. That is, when the motor 10 is turned on by pressing the start button 14 and starts to rotate, the magnet 13 starts to rotate about the imaginary line indicated by the alternate long and short dash line, whereby the magnet 5 faces the magnet 13.
The holder 2 in which is embedded is configured to start to rotate about the virtual line indicated by the alternate long and short dash line as the central axis. A heating mechanism 15 is provided below the holder storage cup 6. Further, 16 is a cleaning pilot lamp and 17 is a heating pilot lamp. When the contact lens cleaning device is configured as described above, for example, a conventionally provided soft contact lens cleaning liquid is placed in the holder storage cup 6, and the soft contact lens 1 contaminated with protein or the like is stored in the holder 2. Place it on the concave part 2a, and from this top, hold the holder 3
Cover the convex surface 3a of the soft contact lens 1 so that it faces the soft contact lens 1, and put it in the holder storage cup 6 containing the cleaning liquid for the soft contact lens. Then, close the lid 7 and press the start button 14. The rotation starts, and the dirt attached to the surface of the soft contact lens 1 is removed. In particular, it becomes possible to cleanly remove even stains of protein firmly attached to the surface of the soft contact lens 1. That is, even if the stain is hard to be removed by the conventional cleaning liquid such as protein on the surface of the soft contact lens 1, this stain is easy because the abrasive 4 is provided on the concave surface 2a. Can be removed. Moreover, at the time of this removal, the soft contact lens 1 and the concave surface portion 2a of the holder 2 are not strongly pressure-bonded to each other, so that the material of the soft contact lens 1 itself is not greatly polished, and the optical It does not have the drawback of drastically changing the sex. Further, the driving force from the motor 10 is not directly transmitted to the holder 3, but this is because when the holder 2 rotates, the soft contact lens 1 also rotates accordingly.
Therefore, there is a relative rotation between the holder 3 and the soft contact lens 1, whereby the stains on the inner surface side of the soft contact lens 1 can be removed. As described above, since the inner surface side of the soft contact lens 1 is less contaminated by adhesion of proteins and the like than the outer surface side, the holder 3 does not need to be directly rotated by the force of the motor 10, that is, the holder 2 and the soft contact lens. Contact lens 1
It is sufficient that the relative velocity between the holder 3 and the soft contact lens 1 is smaller than the relative velocity between. Then, when the motor 10 stops its operation after a predetermined time,
The soft contact lens cleaning liquid in the storage cup 6 is discharged to the drainage tank, then clean water is supplied from the cleaning water tank 8 into the storage cup 6, and the motor 10 is operated for a predetermined time to rinse the soft contact lens 1. Washing is performed, and after this rinse for a predetermined time, the heating mechanism 15 is operated for a predetermined time while the clean water is contained in the storage cup 6, and the soft contact lens 1 is boiled at a temperature of about 80 to 100 ° C. After sterilizing for a predetermined time, this water is drained to the drainage tank, then the soft contact lens preservative solution is supplied from the soft contact lens preservative solution tank 9 into the storage cup 6, and in this state the soft contact lens 1 is preserved until the next day. Will be done.
