Definitions

  • This invention relates to the maintenance and hygiene of the eye, specifically washing proteins, eyelash and foreign objects from the eye. Background—of the invention
  • Sacks discloses device with an eye chamber in which eyewash liquid moves in a direction transverse to the axis of the chamber opening and along the eye surface. Mr. Sacks tried to achieve an effective eye washer design but the design is still inadequate. It may be expensive to make. There are possibilities of flaws such as focusing of eyewash liquid towards the eye improperly and if filter 8 is clogged, it could damage the eyeball due to the pressure build up in chamber 3. Further possibilities of eyewash liquid contamination, high quantity of eyewash liquid utilization due to separate sump for the eyewash liquid and a pump to pump the eyewash liquid etc. Comparing to Mr. Sacks's device, The Handheld Eye Washing apparatus covers all of the eye and area around the eye.
  • an eyecup has a stirring mechanism to stir the eyewash liquid inside of it during utilization and it has an appropriate opening with an appropriate width rim contoured to fit the eye orbital. It has ample room for the eyelids and eyeball movement. Its rim compensates orbital variation, seals better and comforts around the eye. Further, an optional soft-liner may be added to the rim.
  • the stirring mechanism consists of an agitator and a driver for the agitator. The agitator is inside and the driver and its operating necessities are outside the eyecup. In some cases eyecup is made separable from driver means as an adapter eyecup, similar to electric toothbrush head from the driver and electric toothbrush driver is used as a driver for this eyecup. Its access port is made according to the brand to be utilized.
  • Last but not least an eyecup is built around the toothbrush head and bristles of the toothbrush head are replaced with an agitator.
  • the contour of the left and right eyes is different.
  • This device has a universal rim; it may be made contoured to the left and right eye individually or joint for both eyes.
  • the eyecup of this apparatus has a grille between the rim and the agitator to protect the eye injury from the moving parts.
  • a magnetic strip to attract ferrous Mattel during the utilization.
  • components of the Handheld Eye Washing Apparatus may be laid out differently and an eyewash liquid warmer may be added to this apparatus. Depending on consumer and the manufacturing needs, this eyecup can be made in sections and assembled accordingly.
  • a single driver may be used with multi eyecups by making the driver detachable from the eyecup.
  • To utilize user doesn't need to move head side to side or tilt backward. Just fill the eyecup with eyewash liquid or even with clean water at room temperature. Tilt the head forward to place the eyecup, rim matching against the eye orbital, hold it firmly, bring the head straight up, operate the stirring mechanism and it is done. To remove the eyecup for cleaning storage reverse the procedure.
  • the object of this invention is to provide a handy, portable and an inexpensive hygiene-aiding apparatus for the eye and it is well achieved. It provides an effective flow of eyewash liquid to flush out the proteins and foreign materiel from the eye and it is a boon for the contact lens wearers.

Abstract

L'invention concerne un appareil d'irrigation oculaire comprenant une oeillère. Cette oeillère renferme un liquide de lavage oculaire permettant de procéder à des lavages oculaires. OEillère présente un rebord plus large profilé pour l'orbite de l'oeil et repose sur la zone de l'orbite de l'oeil. De plus, cette oeillère comprend un dispositif agitateur interne, il permet de brasser le liquide de lavage oculaire pendant l'utilisation. Les éléments du dispositif agitateur sont fixés à cette oeillère en conséquence. La puissance et la durée du brassage sont prédéterminées de manière à éviter tout dommage de l'oeil. L'appareil susmentionné est conçu pour permettre le mouvement des paupières et du globe oculaire à l'intérieur de oeillère, au cours de son utilisation. Le rebord de oeillère compense les irrégularités de l'orbite et élimine la sensation d'inconfort autour de l'oeil. Le rebord peut être pourvu d'un revêtement d'étanchéité permettant d'augmenter le confort et l'étanchéité du liquide autour de l'oeil. En outre, une grille placée entre le rebord et l'agitateur permet de tenir l'utilisateur à distance de l'agitateur, une bande magnétique peut être placée à proximité de la partie inférieure du rebord afin d'attraper des particules métalliques ferreuses lorsque l'appareil est utilisé dans un environnement industriel. Dans certains cas, oeillère ne comprend pas mécanisme d'entraînement, ainsi elle peut s'adapter au mécanisme d'entraînement d'un support de brosse à dents électrique.
