Description

Contact lens putting on and taking off device {APPARATUS FOR WEARING AND DETACHING CONTACT LENS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact lens attaching and detaching device, and more particularly, to a contact lens attaching and detaching device capable of easily attaching and detaching a contact lens to the eye.

In general, the contact lens is used as a substitute for the eyeglasses by directly attaching the lens directly to the front of the eyeball.

Unlike normal glasses, such contact lenses have no aberration because the optical axis of the eye and the lens always coincide with each other, and there is no difference in the size of the retina due to the difference in refraction on the left and right, so that the object is not seen or doubled, so the field of view is wide. Losing has the advantage. In addition, the contact lens provides the advantage that even if there are irregularities or light turbidity on the eye's cornea surface, the diffuse reflection is improved and the vision is improved, while the detachment and detachment of the lens are not apparent. It is used to make good.

However, in order to wear such contact lenses to the eye, the contact lenses stored in physiological saline or preservatives are caught by the hand and worn on the eyeballs, so there is a risk of foreign substances flowing between the eyeballs and the contact lenses, which is unsanitary, and wearing the contact lenses. There is a problem that is inconvenient to do.

Accordingly, it is an object of the present invention to provide a contact lens attaching and detaching device which can detachably attach and detach a contact lens to an eyeball.

The link 55 has a bar shape, one end of which is rotatably coupled to the link supporting portion 21 of the main body 11 of the arm 10 by a rotation pin 57, and the other end of the link 55 is connected to the connecting pin 59. It is coupled with the link coupling rod 49 by the. Accordingly, as the main body 11 of the arm 10 approaches each other, the link 55 pivots around the pivot pin 57, thereby raising and lowering the movable part 40.

On the other hand, the contact lens attachment and detachment device 7 according to the present invention, the pair of arms (10) and the spring 61 which is elastically urged in the direction in which the arms 10 are spaced apart from each other, and a pair of arms ( It further has a guide (65) provided between the 10 to guide the lifting of the movable portion (40).

In this embodiment, the spring 61 is provided in pairs, and each end of the spring 61 is supported by the spring support 23 of the main body 11 of the arms 10 which face each other.

The guide 65 is made of a tubular body, and is penetrated through the penetrating portion 15 of the pivot shaft coupling portion 13 of the arm 10. The auxiliary spring 51 of the movable portion 40 is accommodated on the inner circumferential surface of the guide 65, and the lens attaching and detaching rod 47 and the link coupling rod 49 are partially accommodated. The outer circumferential surface of the guide 65 is slidably supported by the pair of pivot shafts 17. Accordingly, the rods 47 and 49 and the auxiliary springs 51 of the movable part 40 are guided up and down along the inner circumferential surface of the guide 65.

With this configuration, the operation of the contact lens detachable apparatus according to the first embodiment of the present invention will be described.

First, in order to wear the contact lens 9 on the eyeball, as shown in FIG. 4, the handles 25 of the pair of arms 10 are held, and the main body 11 of the pair of arms 10 is held. Rotate to approach each other.

At this time, as the main body 11 of the pair of arms 10 approaches each other, the spring 61 for elastically interconnecting the pair of arms 10 is compressed and the pair of arms 10 The extensions 31 are spaced apart from each other. At the same time, as the rods 47 and 49 and the auxiliary springs 51 of the movable portion 40 are raised, the lens detachable portion 41 is also raised so that the lens detachable portion 41 is an extension of the pair of arms 10. It protrudes from the end area of 31, and the lens attachable / detachable part 41 and the extension part 31 of the arm 10 do not mutually generate | occur | produce.

Next, in a state in which the extension portions 31 of the pair of arms 10 are spaced apart from each other, the lens detachable portion 41 may use the contact lens 9 stored in a physiological saline solution, a preservative solution, a contact lens container, or the like using surface tension. To the lens mounting portion 45.

Subsequently, the upper and lower eyelids of the eye are supported by the eyelid support 33 of each arm 10 so as to open the eyeball, and then the contact lens 9 mounted on the lens detachable portion 41 approaches toward the cornea of the eyeball. The contact lens 9 is attached to the cornea of the eyeball while appropriately adjusting the approaching distance of the pair of arms 10 and separating the upper and lower eyelids of the eyeball. At this time, the contact lens 9 is detached from the lens attachment / detachment part by the surface tension with the eyeball, and is in close contact with the cornea of the eyeball.

When the contact lens 9 is in close contact with the cornea of the eye, the contact lens attachment and detachment device 7 is separated from the eye, and the force applied to the pair of arms 10 to approach each other is removed. The main body 11 of the pair of arms 10 are separated from each other by the tension force, and each extension 31 of the arm 10 is approached to each other. At this time, as the rods 47 and 49 and the auxiliary springs 51 of the movable portion 40 descend, the lens attachable / detachable portion 41 also descends, so that the lens attachable / detachable portion 41 extends the pair of arms 10. It is located between the portions 31, the lens detachable portion 41 and the extension portion 31 of the arm 10 does not cause mutual interference.

As a result, the contact lens attaching and detaching device 7 returns to its original state, as shown in FIG.

On the contrary, in order to detach the contact lens 9 from the eyeball, the lens attaching and detaching part 41 is rotated so that the main body 11 of the pair of arms 10 approaches the contact lens 9 of the eyeball. The contact lens 9 is detached from the eye by bringing the detachable portion 41 into close contact with the eye contact lens 9 and then separating the contact lens attaching and detaching device 7 from the eye.
