Description

[Detailed Description of the Invention] The present invention relates to a two-electrode connection structure of a contact lens electrolytic sterilizer, in which the main body housing the power supply unit and the disinfection container can be attached and detached each time it is used.

Conventionally, when contact lenses are electrolytically disinfected, a method of washing and disinfecting them with a sodium hypochlorite solution obtained by electrolyzing saline is used, but contact lens electrolysis using this type of disinfection method is The sterilizer is equipped with a connection structure for the purpose of supplying electricity to the main body, which houses the sterilization container and the power supply, because it is attached and detached each time it is used. However, this type of connection structure has a contact point molded from a material such as conductive rubber in the fitting recess provided on the main body side, so it cannot be used with physiological saline or electrolytic solution used for disinfection. Even if a small amount of the sodium hypochlorite solution adheres to or drops onto this contact, it will be able to conduct electricity, and if the disinfection container is fitted and disinfected, electrolysis will occur between the contacts on the main body, and the disinfection will continue. Because of this, the electrolysis inside the container becomes unstable and a disinfectant solution with a normal concentration is not produced, and even if contact lenses are cleaned and disinfected with the disinfectant solution, it is not sufficiently effective and the lenses may be worn with contaminated bacteria remaining. There is a danger of damaging your eyes. Further, if electrolysis occurs between the contacts on the main body side, there is also a drawback that the contacts are extremely worn out.

The present invention has been made to eliminate these drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a sterilization container made of synthetic resin, and 2
is an electrode body for supplying electricity to the disinfection container 1;
This has a structure in which the electrolytic electrode 3 is baked onto the top surface of the ceramic substrate, and the sterilization container side contact 4 is baked onto the bottom surface of the ceramic substrate, and in order to conduct electricity from the bottom surface to the top surface, it is possible to conduct electricity by providing a conductive hole on the side surface or both sides of the ceramic substrate. This electrode body 2 is fixed to the upper surface of the sterilization container 1 via a packing 5 using an outer cover 6. Reference numeral 7 has a power supply part 8 on the main body side with a structure such as storing a battery inside, and 9 is a drainage groove provided at the bottom of the insertion part of the disinfection container 1 on the main body side 7. .
This drain groove 9 is also provided with a drain port 10. In addition, the electrode body 2 is inserted into the outer cover 6.
The sterilization container 1 is attached and detached each time it is used. Reference numeral 11 denotes a pair of contacts on the main body side, the core of which is made of conductive rubber or the like into a cylindrical shape, and the periphery of this is supported by a support part protruding from the drain groove 9 on the main body side 7. ing. Therefore, the main body side contact 11 and the disinfection container side contact 4 are connected to the disinfection container 1.
It has a structure that allows easy connection and energization if it is connected to the fitting part on the main body side 7 each time it is used.

By the way, in such a separate type contact lens electrolytic sterilizer, the main body side 7 and the disinfection container 1 are repeatedly connected and detached each time they are used, so that each time the disinfectant solution leaks from the disinfection container 1 and reaches the contact point with the main body side 7. However, in the present invention, a protrusion is provided on the main body side 7, and a main body side contact 11 is provided on this protrusion, and a drain groove 9 and a drain port are provided on the bottom of the protrusion. 10, the above-mentioned defective electrolysis does not occur, and since no foreign matter is allowed to enter here, the structure is such that problems related to conduction do not occur.

As is clear from the above structure and usage conditions, the present invention has the following effects.

In other words, in this invention, since the main body side contact point is provided that protrudes from the bottom of the main body side drain groove, even if washing water or physiological saline drips between both contacts, the main body side contact head and the electrode body can be easily removed. Stable electrolytic disinfection can be carried out without any accidents such as adhesion between the contact point of the device and the structure of the present invention.In addition, with the structure of the present invention, the cleaning water and physiological saline dripped into the drain can be drained from the drain hole provided on the bottom. Since it is discharged, it is easy to clean and has the effect of preventing the adhesion of foreign matter and dirt.
