Abstract

PURPOSE:To prevent a lens from being cracked by storing an object to be washed in a storage case together with washing liquid, inserting the storage case into a washing vessel and applying oscillation to wash the object by supplying the output of an oscillation circuit to an oscillator. CONSTITUTION:In the body case 1, an oscillator 3 which is oscillated by the high frequency voltage generated in an oscillation circuit member 2 is held by an oscillator supporting base part 1C projected from the inside of the bottom part 1A of the body 1 via a vibration-proof member 4 which is engaged in the annularly recessed part 1D formed on the upper part of the part 1C. In the case that a contact lens 6 is put in the washing vessel 5, the lens 6 is held in a transparent cylindrical storage case 8 by being seized with the arcuate chucks 9 provided on the lower plane of each cap 10 of the case 8. The washing liquid is charged in the storage case 8 with the contact lens 6 held by the chuck part 9, and the whole of the storage case 8 is put in the washing vessel 5 filled up with water, so that the contact lens 8 is held is the washing liquid without being directly brought into contact with the washing vessel 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cleaning device for cleaning contact lenses.

BACKGROUND OF THE INVENTION Conventionally, contact lenses have been cleaned by hand using a special cleaning agent, or by soaking them in a cleaning solution and rinsing them with water.

It is being

Problems to be Solved by the Invention However, with long-term use, secretions in lachrymal fluid, especially proteins, adhere to the surface of the lens, degrading the performance of the lens. In particular, oxygen-permeable hard contact lenses and soft contact lenses have proteins attached to their permeable pores, which cannot be removed with ordinary cleaning solutions. To do this, we have to use an enzyme-based protein remover and soak the lens in the solution for 3 to 10 hours to remove the protein and prevent the lens from becoming cloudy, a process that must be carried out once a week. Must be.

However, this process alone cannot completely remove the protein adhesion, and if this process is repeated for a long period of time, oxygen permeability will deteriorate. In addition, the protein removal agent has a high drug price per treatment, making it expensive in the long run.

In addition, a cleaning device called an ultrasonic cleaner is often used to remove stuck dirt, and it is used to clean glasses and dentures other than contact lenses. As shown in FIG. 5, this container is large, making it difficult to use for cleaning small items such as contact lenses, and also requiring a large overall space, which is inconvenient for use on a trip. Also, with commercially available ultrasonic cleaners, the energy of the ultrasonic imaging is too strong, so if there is even a small scratch on the lens, the lens will break from that scratch. There was a problem with it being put away.

Means for Solving the Problem The present invention provides a cleaning container into which a removable object to be cleaned can be inserted together with a storage case so as to protrude from the upper surface of the main body.
A vibrator that vibrates at high frequency in contact with the bottom of the cleaning container is disposed, a high frequency oscillation circuit is built in the main body, and the output of the oscillation circuit is supplied to the vibrator, while a storage for the object to be cleaned is provided. A case is provided, the object to be cleaned is stored in the storage case together with a cleaning liquid, the storage case is inserted into the cleaning container, water is poured therein, and the object is cleaned while being photographed.

Effect The effect of the technical means of the present invention is to store the object to be cleaned together with the cleaning liquid in the storage case, fill the cleaning container with water, and vibrate it.
Chives to wash. In addition, a vibrator vibrated at high frequency by an oscillation circuit emits ultrasonic vibrations to the cleaning container, and the ultrasonic waves are transmitted to the contact lens through the liquid filled in the cleaning container to remove dirt.

Embodiment Fig. 1 is a sectional view of an embodiment of the cleaning device of the present invention, Fig. 2 is a perspective view of the same, Fig. 3 is a perspective view of a storage case containing contact lenses, and Fig. 4 is a perspective view of the contact lenses. The figure shows.

The structure of the cleaning device of the present invention will be explained.

1, 2, 3, and 4, inside the main body case (1) is a vibrator (3) that vibrates due to the high frequency voltage generated by the oscillation circuit member (2). It is attached via a vibration isolator (4) fitted into an annular recess ID provided inside the upper part of the vibrator support part 1C which integrally projects inward.

The transducer support IC is attached to the main body cover IB of the main body case (1).
A cleaning container (5) with a rectangular hole located directly above it and an opening protruding from the main body cover IB is attached to the transducer support part I.
The vibrator (3) K fitted into the vibration isolator (4) of C is mounted. Ultrasonic vibrations are transmitted to the cleaning container (5) by the vibrator (3). α3 is a battery for power supply.

Cleaning container (5) for cleaning contact lenses (6)
) until the object to be cleaned is completely submerged in the liquid, and place the contact lens (6) into it. Then, turn the timer switch (7) to set the time and turn on the switch. Contact lenses (6)
can remove dirt stuck to itself using ultrasonic vibrations.

When putting the contact lens (6) into the cleaning container (5),
Usually, as shown in Figure 3, a transparent cylindrical case (8) that stores a contact lens (6) has a chunk provided on the lower surface with an arc-shaped tip that holds the contact lens (6). A cap with part (9) (stores 11).

While holding the contact lens (6) in the chunk part (9)K of the cap (full), pour the cleaning liquid into the storage case (8), and fill the storage case (8) with the cleaning container (5) filled with water.
You can also wash it by putting it in it. Contact lenses (8
) can be held in the cleaning liquid without directly touching the cleaning container (5).

The cleaning container (5) K is provided with an annular locking portion Q+l on the lid of the main body, which locks on B, so that the main scale (t) K does not fall down.

In the present invention, after storing contact lenses in a cleaning container,
Turn the timer switch (7) to select the time and turn on the switch. The contact lens (6) can remove dirt stuck to itself by ultrasonic vibration. Since the cleaning container (5) of the present invention is placed together with the case (8), the cleaning container (5) is slightly larger than the case (8). It is cordless so you can carry it with you when traveling.

Effects of the Invention According to the present invention, contact lenses can be cleaned quickly and reliably using ultrasonic waves. Furthermore, since the cleaning container can be made smaller, a smaller amount of cleaning liquid can be used. Since the vibration energy can be controlled specifically for contact lenses, there is no chance of accidental breakage of contact lenses, an advantage that ordinary ultrasonic cleaners do not have. Also,
The main body itself can be made smaller and space-saving because it is exclusively used for contact lenses.
