Abstract
E' reso noto un dispositivo di riscaldamento e di mantenimento del calore per il trattamento di rimozione delle proteine per lenti a contatto comprendente un recipiente termoisolato avente un'apertura superiore per introdurre l'acqua ad alta temperatura. E' fornito un coperchio termoisolante per chiudere l'apertura superiore per preservare l'energia termica dell'acqua ad alta temperatura dentro al recipiente. Un portalenti avente due contenitori separati, ognuno dei quali è riempito con una certa quantità di soluzione per il trattamento di lenti a contatto morbide e in ciascuno dei quali viene deposta una lente, viene introdotto nel recipiente di acqua ad alta temperatura per avere i due contenitori immersi nell'acqua ad alta temperatura e per scaldare la soluzione trattante ad una temperatura di avviamento della reazione così da avviare la reazione tra la soluzione trattante e i residui contaminanti sulle lenti a contatto. Le lenti a contatto così trattate possono poi essere ulteriormente pulite strofinandole con le mani in una soluzione convenzionale per la pulizia di lenti a contatto morbide. Le lenti a contatto così pulite sono poi immerse in soluzioni di immersione convenzionali per diluire i residui di soluzione trattante.A heating and heat maintaining device for the treatment of removing the proteins for contact lenses comprising a heat-insulated container having a superior opening for introducing the water at high temperature is disclosed. A thermal insulating lid is provided to close the upper opening to preserve the thermal energy of the high temperature water inside the container. A lens holder having two separate containers, each of which is filled with a certain amount of solution for the treatment of soft contact lenses and in each of which a lens is deposited, is introduced into the high temperature water container to have the two containers immersed in high temperature water and to heat the treating solution to a reaction starting temperature so as to start the reaction between the treating solution and the contaminating residues on the contact lenses. The contact lenses thus treated can then be further cleaned by rubbing them with your hands in a conventional solution for cleaning soft contact lenses. The contact lenses thus cleaned are then immersed in conventional immersion solutions to dilute the residues of the treating solution.
