Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sterilizing and disinfecting method for preventing microbial contamination of contact lenses.

[0002]

2. Description of the Related Art Conventional sterilization of contact lenses is 2
Two methods are used. One is disinfection by boiling,
Usually, it is carried out by using a boiling disinfecting device which can be washed by rubbing with a dedicated cleaning agent, immersed in a rinse solution or physiological saline and boiled at 100 ° C. for 10 to 20 minutes. The other method is chemical disinfection with a 3% hydrogen peroxide solution, which is a dipping treatment for 30 to 60 minutes,
A method of neutralizing with sodium thiosulfate or catalase is used. In addition, disinfection with thimerosal is also used overseas. These methods have proven themselves over many years and are effective sterilization methods.

[0003]

It is said that boiling sterilization, which is the mainstream in Japan, is highly safe in that it does not use harmful compounds. However, the heat treatment called boiling accelerates the deterioration of the contact lens itself. It has the effect of shortening the lens life and also denaturing and fixing biofouling components such as proteins, lipids, mucins and calcium adhered to the contact lens, which may cause deformation and discoloration of the contact lens. Furthermore, wearing such a contact lens causes eye damage and is dangerous. The chemical sterilization method using hydrogen peroxide has a lesser effect than the boiling sterilization in terms of contact lens deterioration, but deterioration due to oxidation is recognized. Furthermore, since hydrogen peroxide itself has a denaturing effect on living tissues, it must be neutralized. If the neutralization process is insufficient, it poses a high risk because it may cause serious eye damage.

Further, Japanese Patent Laid-Open No. 57-14821 discloses a sterilization method using chlorine dioxide. Chlorine dioxide has a strong bactericidal action and a bleaching action, but it needs to be sufficiently neutralized, which is dangerous. JP-A-56-6845
No. 4, JP-A-57-153653, JP-A-KAI-3
JP-A-21246 discloses a method of generating hypochlorite by passing an electric current through saline. However, in these methods, since the negative electrode part and the positive electrode part are not separated from each other, there is a drawback that hypochlorite is generated only in the vicinity of the electrode and sufficient disinfection cannot be performed.

Therefore, the present invention has been achieved through intensive research with the object of providing a safer and more reliable sterilization method and apparatus.

By electrolyzing an aqueous solution of electrolyzed water, alkaline ionized water is produced on the cathode side and acidic ionized water is produced on the anode side. In the alkaline ionized water, a positive electrolyte (Na ⁺ , C
It includes a ^2+, etc.), the acidic ionic water anionic electrolyte (Cl ^-, S ^-
Etc.) are included. It is generally known that alkaline ionized water exhibits a riching action, a dissolving power, a penetrating power and a detergency for softening a substance, and acidic ionized water has a cleaning action, a bactericidal action and a bleaching action. A device for producing this ionized water is already on the market and can be purchased from Omco Co., Ltd., Asahi Glass Engineering Co., Ltd., and the like.

The present invention focuses on the bactericidal action, cleaning action and bleaching action of acidic ionized water, and this acidic ionized water is originally produced by electrolysis of inorganic salts and compounds contained in water. To expect a more sufficient disinfecting effect, an aqueous solution of saline, boric acid or the like can be used.
When salt water is used, hypochlorite is generated on the positive electrode side and hydroxide ions are generated on the cathode side. Since the production concentration of hypochlorite depends on the electrolysis time and the salt concentration, the optimum concentration can be obtained by adjusting these.

Actually, the disinfecting effect of acidic ionized water is that if the pH is about 5, E. coli and the like can be easily disinfected,
Further, when the pH is about 3 or less, salmonella, methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa can be disinfected in a short time. Furthermore, the cleaning action and the bleaching action are useful in terms of cleaning care of contact lenses.

Part 11 is a packing for partition walls. The structure of the device B of the present invention is basically the same as that of the device A, but is characterized in that the lid is a screw cap type. Although these are the basic configurations, there is no limitation whatsoever even if a difference in schematic structure and a component configuration that can be easily simplified by conventional techniques are used.

The device configuration of the device C of the present invention is shown in FIGS. The device consists of an electrolyzer unit and a power unit, and the electrolyzer unit is the device A and B.
The power supply unit has a configuration similar to that in which a plug, an electric control circuit, and the like are housed. Both of these unit parts have a structure that can be attached and detached by connecting terminals.
