  • the first part of the present invention is the composition of an effervescent tablet.
  • the effervescent tablet has the following properties it cleans, it keeps sterile solutions, sterile, it moistens the contact lenses and it preserves contact lenses.
  • the second part of the present invention is directed to the use of a special filter system that filters a measured amount of running tap water; the water has to be drinkable.
  • the filter is so chosen that the filtered water becomes sterile.
  • This sterile water is directly available in an inner container wherein the effervescent tablet is put in.
  • the soiled contact lenses are put separately in a standard holder for contact lenses; the holder is than screwed on top of the inner container.
  • the second part of the invention what refers to the special filter system, may be best understood by referring to the drawings.
  • Fig.l shows a standard holder for contact lenses wherein the left contact lens is separate from the right contact lens. Usually the standard holder for contact lenses is assembled in the stopper.
  • the special filter system exist of two containers namely an inner container (fig.2) witch have a special filter in his bottom and an outer container (fig.3).
  • the inner container have an outer screw tread witch can be screwed in the outer container witch is made with an inner screw tread that fits.
  • Running tap water if it is drinkable
  • the inner container is screwed in the outer container with the water inside; the pressure that then occurs filters the water trough the filter in the bottom of the inner container.
  • the stopper with the separate contact lenses is screwed on the top of the inner container.
  • the stopper can be screwed on the inner container; witch contains the filtered running tap water.
  • the present invention is a combination of the use of an effervescent tablet with the properties of a multi purpose solution for cleaning and disinfection of contact lenses and the special filter system that gives a container with the adjusted amount of sterile water a container wherein the standard holder for contact lenses is screwed. 1. EFFERVESCENT TABLET.

Abstract

L'invention concerne un comprimé effervescent « tout-en-un » stable pouvant être utilisé dans un système de filtre spécial. L'unité de filtre comprend un contenant interne et un contenant externe. Il y a également un support normalisé destiné aux verres de contact placé dans la fermeture du contenant interne. Celui-ci comprend un filetage de vis sur l'extérieur et le contenant externe un sur l'intérieur. Le contenant interne peut être vissé dans le contenant externe. Le contenant interne comprend également un filtre membrane (diamètre des pores 0,2µm) dans le fond. Le vissage du contenant interne dans le contenant externe, rempli d'eau du robinet jusqu'à la marque, permet d'obtenir la quantité exacte d'eau stérile permettant de dissoudre le comprimé effervescent. La fermeture, au niveau de laquelle les verres de contact sont placés de manière distincte, est vissée sur le contenant interne par la suite. Cette procédure permet de nettoyer, désinfecter, rincer ou conserver les verres de contact.
