Description

INJECTOR DEVICE FOR CONTACT LENSES.-

OBJECT OF THE INVENTION

The following invention, as expressed in the statement of the present specification, refers to a contact lens injector device, which is useful for the placement of contact lenses in the eyeballs, being conceived and performed in order to obtain numerous and notable advantages over other existing means of analogous purposes.

Thus, the device has as an essential object that the contact lenses are properly attached to it and can be placed in the eyeballs, without having to manipulate the eyelids or the lenses with the fingers.

Thus, the contact lens injector device has as an essential objective to open the eyelids and place the corresponding contact lens in a simultaneous maneuver.

For this, the injector device has a hollow cylindrical body in general, to which the eyelid opening clamps are rotatably joined and through which a carrier cylindrical piece, by one of its bases, of the receiver of the contact lens is movable and which by its other base is rotatably fixed to a pair of strips that, at its other end, are rotatably joined to one end of the clamps.

Likewise, in a variant of practical execution of the invention, the contact lens injector devices are based on three pieces joined together, so that between them the lens is fixed and in turn we can apply them to the eyes.

SCOPE.

The contact lens injector device is of special application for the placement of contact lenses in the eyeballs without the need for manipulation of the eyelids or the lenses.

BACKGROUND OF THE INVENTION

Many are the users of glasses who cannot use contact lenses due to difficulties or problems in vision because they do not accept contact lenses, so the only possibility is to continue with glasses. Likewise, we can not only consider this inconvenience but also the disadvantage that when placing the contact lenses with the hands, a large amount of bacteria can be transferred to the eyes, which can cause vision problems.

On the other hand, some devices or means are known for carrying out the fixation of the lens in the eye but none of them resolves the opening and fixing of the eyelid.

Thus, as is known, the eyelid is a reflex muscle that cannot be controlled, so that existing devices only fix the lens to a membrane so that it is attached to the apparatus.

In this way, we can consider the Spanish Utility Model documents U0234746, U0278057 and ES 1018997, so that in document U0234746 a "inserter for all types of contact lenses on the cornea", constituted by a trunk body, is described - hollow conical provided on its lateral surface of a shaft or rod topped in a suction cup in which the lens to be placed is placed.

In document U0278057 a "device for the placement of contact lenses on the eye" is described, constituted by a hollow cylindrical body that by one of its ends has a support adapted to receive a lens and that lets the ambient light pass and whose inner wall is reflective.

In document ES 1018997 a "contact lens device" is described, consisting of an elongated single piece body provided with an axial hole with respect to one of its bases provided with a radial expansion for the location of a lens and whose axial hole extends from radial form, in proximity to the base opposite to that of the expansion to obtain the vacuum.

Likewise, we can consider the invention patent ES 2058022 in which a "contact lens extractor" is described, which is constituted by a body with a cylindrical side endowed with a notch that defines both arms with their free ends in bevel and equipped with a curved concavity and on the other hand defines a handle.

Likewise, we can consider documents DE 10021504 and FR 2710259, so that in document DE 10021 504 in which a device for the insertion of contact lenses is described, which is constituted by a hollow trunk-conical body in which a finger and a location element of the lens is inserted for placement, while in the document FR 2710259 describes a device for the insertion of a contact lens, consisting of a base body, generally cylindrical, into which an outstanding member has been inserted by both bases of the base body, which at one of its ends has several arms with support surfaces on which the lens is located.

Regarding the eyelid opening tweezers, there are numerous systems to tighten the eyelashes, including different clinical medical elements that achieve the support of the eyelids although the solution to do so has not been given in a frontal way since the elements that exist are always lateral supports

DESCRIPTION OF THE INVENTION

In order to solve the drawbacks cited herein, a contact lens injector device is described which has a new structure based on which it is achieved that the contact lenses are fixed to the eyeballs with great efficiency, in a simple manner. and without any problem.

In this way, the device comprises:

4 a hollow cylindrical body;

4 a cylindrical body housed inside the hollow cylindrical body;

4 a contact lens receiver, and;

4 a clamp with its arms associated with the hollow cylindrical body, whose arms, at one end, are finished off in a slightly curved support.

In a preferred embodiment of the invention, the cylindrical body housed inside the hollow cylindrical body has, on one of its bases, the contact lens receiver.

On the other hand, the hollow cylindrical body has on its outer lateral surface and in axial position two pairs of lugs facing diametrically to which the arms of the clamp are rotatably joined by one of whose ends are finished off in the support - A - slightly curved and at whose other end they are rotatably joined to one end of respective strips that at their other end are rotatably joined to the cylindrical body by the base opposite the contact lens receiver.

The contact lens receiver provided in one of the bases of the cylindrical body housed inside the hollow cylindrical body has a curved-concave external surface.

The base provided with the contact lens receiver of the cylindrical body is in proximity to the end of the arms of the clip that are finished off in a slightly curved support.

In this way, with a contact lens on the receiver of the corresponding contact lens for placement and with the slightly curved supports of one end of the arms of the clip on the eyelids, when acting on the other end of the arms will cause the opening of the eyelids and the simultaneous displacement of the cylindrical body until the contact lens is positioned in the eyeball.

According to the execution described in the same maneuver, that is, when acting on the clamp, the opening of the eyelids and the placement of the contact lens in the eyeball occurs.

In a practical variant of the invention, the hollow cylindrical body has, in one of its bases, the contact lens receiver, which is provided with a central hole communicated with the hollow cylindrical body emptying.

Likewise, in this practical embodiment, the cylindrical body housed inside the hollow cylindrical body exerts a pneumatic pressure, similar to the mechanism of a syringe, on the corresponding contact lens housed in the receiver of the hollow cylindrical body.

In this practical embodiment, the clamp-forming arms that at one end are finished in a slightly curved support, at the other end, are axially movable by the external surface of the hollow cylindrical body manually.

With this configuration and with a contact lens in the receiver of the corresponding contact lens the cylindrical body will be removed keeping the lens under pressure in position, so that with the Slightly curved support of one end of the arms of the clip on the eyelids when acting on the arms of the clip will cause the opening of the eyelids and then with the displacement of the cylindrical body until positioning the contact lens in the eyeball and back impulse of the cylindrical body into the hollow cylindrical body will be positioned the lens in the eyeball.

Thus, once the contact lens is placed in the receiver, the cylindrical body (button) is operated, according to an extraction movement, which will generate sufficient pressure to create a vacuum by fixing the contact lens in avoidance of a free fall. .

In addition, once the device is in this arrangement, the same is placed in front of the eye, placing the symmetrical curved supports on the eyelids and when the slider is operated, the opening of the eyelids is forced at the same time as the lens of the eye contact Once in this position, the button is operated in the opposite direction as it had been done so that the air pressure fixes the lens on the eyeball, that is, introducing it into the tubular body.

According to this execution, the opening of the eyelids will occur in a first maneuver and in a second maneuver the contact lens approach to the eyeball will be produced and, finally, with the insertion of the cylindrical body, the Ia contact lens.

Logically, the receiver of the contact lenses has a central hole communicated with the displacement hole of the button to create the vacuum and drive the lens.

In order to complete the description that will then be made or in order to help a better understanding of the characteristics of the invention, the present descriptive memory of a plane set based on whose figures will be more easily understood innovations and advantages are attached of the device object of the invention.

DESCRIPTION OF A PREFERRED EMBODIMENT. In view of the aforementioned figures and according to the numbering adopted we can observe how the device 1 is constituted by a hollow cylindrical body 2, a cylindrical body 3 housed inside the hollow cylindrical body 2, a contact lens receiver 4 and a clamp 5 with its arms associated with the hollow cylindrical body 2, whose arms, at one end, are finished off in a slightly curved support 6.

Thus, in a practical embodiment of the invention, the cylindrical body 3 housed inside the hollow cylindrical body 2 has, on one of its bases, the receiver 4 of the corresponding contact lens.

On the other hand, the hollow cylindrical body 2 has on its external lateral surface and in axial position two pairs of lugs 7 diametrically facing those that rotatably join, through axis 9, the arms of the clamp 5 by one of whose ends they are finished off in the support 6 slightly curved and at whose other end they are rotatably joined to one end of respective strips 8 which at their other end are rotatably joined to the cylindrical body 3 by the base opposite to the contact lens receiver 4.

The contact lens receiver 4 provided in one of the bases of the cylindrical body 3 housed inside the hollow cylindrical body 2 has a curved-concave external surface facilitating the positioning of the contact lenses.

The base of the cylindrical body 3 provided with the contact lens receiver 4 is in proximity to the end of the arms of the clip 5 that are finished off in the support 6 slightly curved opening of the eyelids 10.

Starting from this configuration, with a contact lens on the receiver 4 of the corresponding contact lens 1 1 for placement and with the slightly curved supports 6 of one end of the arms of the clip 5 on the eyelids 10 when acting on the Another end of the arms will cause the opening of the eyelids and the simultaneous displacement of the cylindrical body 3 until the contact lens is positioned in the eyeball 12.

Thus, according to this configuration, in a single maneuver, the opening of the eyelids 10 and the placement of the contact lens 1 1 in the eyeball 12 will be allowed. In a practical variant of the invention, the hollow cylindrical body 2 has, in one of its bases, the contact lens receiver 4, which is provided with a central hole 10 communicated with the hollow 13 of the hollow cylindrical body 2.

Likewise, the cylindrical body 3 housed inside the hollow cylindrical body 2 exerts a pneumatic pressure, similar to the mechanism of a syringe, on the corresponding contact lens 1 1 housed in the receiver 4 of the hollow cylindrical body 2, causing a vacuum and allowing the contact lens to be in position to avoid possible falls thereof.

The forming arms of the clamp 5 which at one end are finished off in a slightly curved support 6, at the other end, are axially movable by the external surface of the hollow cylindrical body 2, so that in its axial displacement the opening / closing of the pair of supports 6.

Thus, with a contact lens 1 1 in the receiver 4 of the corresponding contact lens, the cylindrical body 3 will be removed keeping the lens under pressure in position when causing a vacuum.

In this way, with the slightly curved supports 6 of one end of the arms of the clip 5 on the eyelids 10 when acting on the arms of the clip 5, the opening of the eyelids 10 will be caused and then with the displacement of the hollow cylindrical body 2 until the contact lens is positioned in the eyeball 12 and subsequent impulse of the cylindrical body 3 into the hollow cylindrical body 2, the lens 1 1 will be positioned in the eyeball 12.

Thus, in this variant, the contact lens injector device 1 is defined by three interlocking parts, defined by a hollow cylindrical body 2 (tubular body 2) with a cylindrical body 5 (push button), in whose hollow cylindrical body 2 A contact lens receiver 1 1 and a clip 5 with a support 6 have been placed at one of its ends for opening the eyelids 10.

On the one hand, inside the hollow cylindrical body 2 incorporates a mechanism, cylindrical body 3 (push button), of pneumatic pressure similar to the mechanism of a syringe.

In Figure 4 relative to an isometric perspective of device 1 the cylindrical body 3 (button) is not observed but, it is observed in figures 5 and 7.

Thus, it can be seen that at the opposite end of the cylindrical body 3 (push-button) to the hollow cylindrical body 2, a receiver 4, of concave curved external surface, is fixed for the placement of the corresponding contact lens 1 1. On the lateral surface of the tubular body 2, in proximity to the end of the receiver 4 of the contact lenses, it has a pair of arms, as a clamp, with one end provided with a curved configuration support and with a protector of gelatinous material with a limited opening, whose function is to place on the eyelids

10 and with minimal pressure, open the eyelids with a sufficient but limited margin and prevent them from closing automatically.

The receiver 4 of the contact lenses can be embedded inside the hollow cylindrical body 2 (tubular body) or fixed on the surface.

The unitary device relative to the practical execution variant relative to figures 4 to 9, is formed by three pieces associated with each other.

The pair of supports 6 are mounted on the outer surface of the hollow cylindrical body 2 in symmetrical and equidistant position, so that the opening mechanism is based on a limited strap that conditions

The maximum opening.

Logically, the receiver 4 has a central hole 10 communicated with the hollow 13 of the hollow cylindrical body 2 through which the cylindrical body 3 is moved (push button in order to create the pressure on the contact lens located therein and its subsequent drive.
