Field

A system and method of providing a toilet aid to individuals who have visuoperceptual challenges. The visual aid is a yellow-green colored attachment that fits on the toilet bowl rim or seat providing an outline of the toilet bowl, thus making it is easier to see and perceive when using the toilet.

Background

When the brain is cognitively compromised by disease or time as a result of dementia, Alzheimer's, age and the like, the transmission of visual information to the brain can be interrupted resulting in reduced or distorted vision. The difficulties that some individuals experience are directly related to the type of dementia they have. For example, Posterior Cortical Atrophy starts in the parietal and occipital lobes, thus compromising depth of perception and visual input. Other dementias affecting vision include Alzheimer's,

Parkinson's disease dementia, dementia with Lewy Bodies, and vascular dementia. Changes to the visual field, problems directing or changing a gaze, reduced ability to detect colors, and depth perception are examples of visuoperceptual challenges individuals face.

Visuoperceptual problems can greatly reduce the quality of life for people with dementia and those with limited vision. Visually impaired or limited vision occurs because of refractive errors, cataracts, glaucoma, age-related macular degeneration, corneal clouding, diabetic retinopathy, as well as neurological conditions due to stroke and trauma. Reduced vision because of dementia or physiological reasons causes complications with toileting.

As the brain loses its ability to process visual data, depth perception becomes difficult for visuoperceptual-challenged individuals. Without contrasting color tones, the toilet appears flat. As a consequence, urinating in a toilet is compromised, especially for men. If a toilet cannot be seen, it is hard to maintain continence. In addition, individuals with visuoperceptual challenges lose their ability to visually process color. Research has shown that the eye is most sensitive to the yellow-green color. The use of the yellow-green color has been effective in assisting Alzheimer's and visually-challenged individuals maintain autonomy. The yellow-green color is represented by pantone colors: 802-C, 2287-C, 2421- C, and 2271-C. The following chart illustrates how the eye responds to light.

https://en.wildpedia.org/wiki/Color_vision^ Many visuoperceptual-challenged individuals desire to live as independently as possible within their limitations. Thus, it is important to enable any such patient to function with as little intervention as possible while improving their quality of life. As such, it is helpful to provide these individuals with a visual aid in using the toilet as their depth perception and their ability to detect colors diminish. In many instances, the color of the toilet bowl and the color of the bowl are the same. For someone with extremely limited chromatic vision, the toilet bowl appears flat against the floor. There is a need to provide a visual aid for use by individuals who are visuoperceptual-challenged to use the toilet independently and effectively. Brief Description of the Drawings

The embodiments described herein are directed to a removable sleeve designed to fit over the rim of the toilet porcelain base. The first embodiment 10 is shown in Fig. 1. The first embodiment 10 includes a u-shaped channel 12. The channel has ends 14 and a length 16. The channel 12 has a cross-section shown in Fig. 3. The cross-section of the channel 12 has sides 18 and a top surface 20. The dimensions of the cross-section are sized to fit over the porcelain rim 22 of a standard toilet 24. The toilet has a standard seat 26 and lid 28 hingedly attached to the rim 22. The toilet rim 22 is adjacent to the opening 30 in the toilet 24. The toilet rim 22 is the top of the toilet basin 32 having inner 34 and outer 36 basin walls. The first embodiment 10 is preferably made of a medical grade polymer for easy cleaning and minimal capacity to retain bacteria and the like. Moreover a medical grade polymer will retain its shape and not easily degrade when exposed to the rigors of sanitization and urine. The first embodiment 10 is preferably yellow-green in color. This can be accomplished with colored polymer or coating the embodiment with a dye or paint of that color. The yellow- green color targets the middle wavelengths of the spectrum, thus maximizing and enhancing the visual perception of the Alzheimer's or visually impaired patient. Preferably the yellow- green color is identified by one or more of the following Pantone colors: 802-C, 2287-C, 2421-C and 2271-C. In use, the user first lifts the seat 26 and lid 28 upwardly to fully expose the toilet rim 22 and basin 32. Then the user positions the first embodiment 10 over the opening 30 of the toilet 24. The ends 14 are positioned adjacent to the hinge for the seat 26 and lid 28. The length 16 of the u-shaped channel 12 is positioned above the rim 22. In addition, the first embodiment 10 is positioned so that the sides 18 are pointed downwardly towards the rim 22 of the toilet 24.

To attach the first embodiment 10 to the toilet 24, the user pushes the first embodiment 10 downwardly so that the sides 18 receive the toilet rim 22. The sides 18 slidingly engage the inner 34 and outer 36 walls of the toilet basin 32. As the user pushes the first embodiment 10 downwardly, the sides 18 receive the toilet rim 22 and travel stops when the top surface 20 rests against the rim 22. In this position, the sides 18 are in frictional engagement with the inner 34 and outer 36 walls of the basin 32. The first embodiment 10, when fully installed, appears as a horse-shoe shaped insert over the toilet rim 22. Once the first embodiment 10 is installed, the patient can see the first embodiment 10 as it rests over the rim 22. This provides a visual aid to the patient and enables him to urinate into the toilet basin 32 with greater accuracy. After the patient has used the first embodiment 10 it may be removed for cleaning. The first embodiment 10 is removed by pulling upwardly on the length 16. This causes the sides 18 to move upwardly relative to the rim 22. As the sides 18 move upwardly they disengage from contact with the inner 34 and outer 36 basin walls. Once the first embodiment 10 is completely removed from the toilet 24, it can be wiped or cleaned as needed. To reuse, the first embodiment is inserted onto the toilet rim 22 as described above. A second embodiment 40 is disclosed in Figs. 4-6. As shown in Fig. 5, the second embodiment 40 includes a top surface 42, inner side surface 44 and outer side surface 46. The second embodiment 40 is shaped to fit over a toilet bowl 50 having a rounded rim 52. Turning to Fig. 4, the top surface 42 is oval-shaped and sized to fit onto the opening of the toilet bowl 50. A flat section 48 is located along a portion of the top surface 42. The fiat section 48 is designed to fit adjacent to the hinges for the toilet seat 26 and lid 28 when installed, as shown in Fig. 6.

To install the second embodiment 40, the toilet seat 26 and lid 28 are moved upwardly so that the toilet bowl opening 50 is accessible. The second embodiment 40 is placed over the toilet bowl opening 50. The shape of the second embodiment 40 is aligned with the shape of the toilet bowl opening 50. In particular, the flat section 48 is placed adjacent to the hinges for the toilet seat 26 and lid 28. Once the second embodiment 40 is aligned with the toilet bowl opening, the user pushed down on the top surface 42 causing the inner 44 and outer 46 walls to slide along the inner and outer rims of the toilet bowl respectively. This is done until the top surface 42 is in contact with the rounded rim 52. Once installed, the patient uses the second embodiment 40 in the same manner as the first embodiment 10.

It should be appreciated that some toilets may have variations in the shape of the bowl and rim. In such cases, the shape of the body of the embodiment will be shaped to accommodate the shape of the toilet bowl and the cross-section of the embodiment will be shaped to accommodate the shape of the rim. This should include but not be limited to oval, squared, rectangular and the like. Moreover, while the embodiments have referred to porcelain toilet bowls, it is appreciated that the embodiments herein described may equally be used on stainless steel, plastic or other toilet bowls. In addition, it should be appreciated that the embodiments described herein would apply equally to toilets or commodes in campers, on boats, portable and bedside toilets and the like.
