The present invention is generally related to a self-adhering occlusion eye patch such that the self-adhering occlusion eye patch has a three-sided diamond shape or rounded triangle shape. In particular, the occlusion eye patch includes a base layer of woven material having a front side screen printed with at least one Food and Drug Administration (FDA) compliant graphical design with a sealant applied over the graphical design, an adhesive layer applied to the entire backside of the base layer such that the adhesive is applied in a horizontal striped arrangement, a black cotton layer is attached on one side to the adhesive layer such that the black layer is smaller in surface area than the base layer, and a white cotton layer is attached to the other side of the black layer such that the black layer and the white layer are approximately 1 mm wide, wherein the white cotton layer is substantially the same in surface area as the black cotton layer. The horizontal striped arrangement of the adhesive creates a self-adhering adhesive surface for the occlusion eye patch that allows the eye patch to be firmly and securely attached to the eye socket area around the eye but also allows the occlusion eye patch to be easily removed. Furthermore, the black layer provides excellent light occlusion properties for the occlusion eye patch. Finally, the overall shape of the self-adhering occlusion eye patch allows the self-adhering occlusion eye patch to be easily and firmly attached to the end user/patient and is comfortable but not too bulky for the end user/patient to wear.
A common known eye ailment among both children and adults is called Amblyopia, which is also known as lazy eye. Amblyopia is the most prevalent neurological defect of vision in children and adults, affecting 2-5 percent of the population. Amblyopia is characterized by reduced vision that cannot be corrected by eye glasses or contact lenses and is not the result of an eye disease. Furthermore, amblyopia can cause a loss of depth perception. Early detection (comprehensive eye examinations) and treatment are the best chances for curing amblyopia. Some of the most well-known treatments include eye glasses, eye drops, eye patches and/or vision therapy.
Prior to the present invention, as set forth in general terms above and more specifically below, it is known, to employ various types of eye patches for use in a variety of medical treatments. See for example, U.S. Pat. No. 3,068,863 by Bowman, U.S. Pat. No. 3,092,103 by Mower, U.S. Pat. No. 3,908,645 by Sandvig, U.S. Pat. No. 4,599,746 by Stoner, U.S. Pat. No. 4,944,040 by Riedel et al., U.S. Pat. No. 5,429,592 by Jenson, U.S. Pat. No. 6,890,551 by Lenz et al., and U.S. Pat. No. 7,584,754 by Pellegrini et al. While these various eye patches may have been generally satisfactory, there is nevertheless a need for a new and improved, self-adhering occlusion eye patch which includes a base layer of woven material having a front side screen printed with at least one FDA compliant graphical design with a sealant applied over the graphical design, an adhesive layer applied to the backside of the base layer such that the adhesive is applied in a horizontal striped arrangement, a black cotton layer attached on one side to the adhesive layer such that the black layer is smaller in surface area than the base layer, and a white cotton layer attached to the other side of the black layer such that the black layer and the white layer are approximately 1 mm wide, wherein the white cotton layer is substantially the same in surface area as the black cotton layer.

The preferred self-adhering occlusion eye patch, according to various embodiments of the present invention, offers the following advantages: ease of use; lightness in weight; durability; improved comfort; improved graphical designs; improved heat dissipation from the eye through the eye patch; reduction in adhesive marks around the eye socket; improved ability to fit around the eye socket; improved breathability; excellent light occlusion characteristics; excellent self-adhering adhesive characteristics; the three-sided diamond shape or rounded triangle shape of the self-adhering occlusion eye patch; and the ability to use the eye patch on children and adults. In fact, in many of the preferred embodiments, these advantages are optimized to an extent that is considerably higher than heretofore achieved in prior, known eye patches.
The above-mentioned features and steps of the invention and the manner of attaining them will become apparent, and the invention itself will be best understood by reference to the following description of the embodiments of the invention in conjunction with the accompanying drawings, wherein like characters represent like parts throughout the several views and in which:
In order to address the shortcomings of the prior, known eye patches, reference is made now to
As shown in
With respect to outer non-woven fabric layer 4, as shown in
A unique aspect of the present invention is the use of the self-adherent adhesive strips 6 on the outer non-woven fabric layer 4 (
With respect to the front side of outer non-woven fabric layer 4, as shown in
Another unique aspect of the present invention is that the use of at least one graphical design 8 allows a wide variety of self-adhering occlusion eye patches 2 to be produced that will appeal to both children and adults. In particular, graphical designs 8 that appeal to adults can be placed on the front of the self-adhering occlusion eye patches 2 as well as graphical designs 8 that appeal to children can alternatively be placed on the front of the self-adhering occlusion eye patches 2.
Located over the at least one graphical design 8 is a conventional sealant layer 10 (
A further unique aspect of the present invention is the use of the sealant layer 10. The sealant layer 10 not only protects the at least one graphical design 8 and allows the non-woven fabric layer 4 to be breathable but the sealant layer 10 protects the self-adhering occlusion eye patch 2 against dirt, dust and other debris that comes into contact with the self-adhering occlusion eye patch 2.
Regarding
A still further unique aspect of the present invention is the use of the inner black padding layer 50. Inner black padding layer 50 substantially prevents (blocks) any light of a preselected wavelength from entering into the eye upon which the self-adhering occlusion eye patch 2 is located but is thin enough such that the overall size of the self-adhering occlusion eye patch 2 is still relatively thin so that the end user should not experience any discomfort when wearing the self-adhering occlusion eye patch 2 and the self-adhering occlusion eye patch 2 will not look to be too bulky.
With respect to
An even further unique aspect of the present invention is the use of the inner white non-woven layer 100. Inner white non-woven layer 100 is breathable but is thin enough such that the overall size of the self-adhering occlusion eye patch 2 is still relatively thin so that the end user should not experience any discomfort when wearing the self-adhering occlusion eye patch 2 and the self-adhering occlusion eye patch 2 will not look to be too bulky. Furthermore, the breathability of inner white non-woven layer 100 allows the self-adhering occlusion eye patch 2 to efficiently dissipate any heat that is created around the eye upon which the self-adhering occlusion eye patch 2 is located.
Regarding the construction of self-adhering occlusion eye patch 2, reference is made to
Once the at least one graphical design 8 and the sealant layer 10 are applied to the front side of outer non-woven fabric layer 4 and the adhesive strips 6 are applied to the back side of outer non-woven fabric layer 4, the inner black padding layer 50 is then centered on the back side of outer non-woven fabric layer 4 and attached to the back side of outer non-woven fabric layer 4 by pressing or forcing one side of inner black padding layer 50 onto the back side of outer non-woven fabric layer 4. It is to be understood that inner black padding layer 50 is retained on the back side of outer non-woven fabric layer 4 by a portion of adhesive strips 6.
After the inner black padding layer 50 has been adhered to the back side of outer non-woven fabric layer 4, the inner white non-woven layer 100 is then conventionally attached to the inner black padding layer 50 by conventional adhesives (adhesive layer 60 in
A still further unique aspect of the present invention is that the centering of the inner black padding layer 50 and the inner white non-woven layer 100 on the back side of outer non-woven fabric layer 4 (
With respect to
Another unique aspect of the present invention is that the self-adhering occlusion eye patch 2 completely fits the area around the eye due to the three-sided diamond shape or rounded triangle shape of the self-adhering occlusion eye patch, but is not of such a size and shape that it creates an unsightly appearance for the end user. It is to be further understood that the overall size of the self-adhering occlusion eye patch 2 can be adjusted so that the self-adhering occlusion eye patch 2 will properly fit either an adult or a child. For example, the overall size of self-adhering occlusion eye patch 2 can be made smaller so that the self-adhering occlusion eye patch 2 can properly fit a child.
A still another unique aspect of the present invention is the overall shape of the self-adhering occlusion eye patch 2. In particular, the overall shape of the self-adhering occlusion eye patch 2 allows the self-adhering occlusion eye patch 2 to be easily and firmly attached to the end user/patient and is comfortable but not too bulky for the end user/patient to wear. This is because the overall shape of the self-adhering occlusion eye patch 2 allows the self-adhering occlusion eye patch 2 to fit more efficiently within the eye socket of the end user/patient due to the very small thickness of the self-adhering occlusion eye patch 2 (the overall thickness of the self-adhering occlusion eye patch 2 is less than 4 mm (preferably less than 3 mm)). Furthermore, the overall shapes of the outer non-woven fabric layer 4, the inner black padding layer 50, and the inner white non-woven layer 100 allow the self-adhering occlusion eye patch 2 to fit more efficiently within the eye socket of the end user/patient. In particular, the outer non-woven fabric layer 4, the inner black padding layer 50, and the inner white non-woven layer 100 are shaped to include a wider portion at the top of the outer non-woven fabric layer 4, the inner black padding layer 50, and the inner white non-woven layer 100 and a narrow potion at the bottom of the outer non-woven fabric layer 4, the inner black padding layer 50, and the inner white non-woven layer 100. Finally, the outer non-woven fabric layer 4, the inner black padding layer 50, and the inner white non-woven layer 100 include curved edges that allow the self-adhering occlusion eye patch 2 to fit more efficiently within the eye socket of the end user/patient.
