[Detailed description of the device] [Industrial applications]

The present invention relates to a method for producing a contact lens preservation solution.

[Background of device]

Contact lens preservatives have been used for the storage of contact lenses. This type of contact lens preservative has hitherto been treated with a water-soluble bactericidal agent or preservative (hereinafter, antibacterial agent). The added one is used. The purpose of adding the antibacterial agent is to impart an antibacterial effect to the preservative solution when the contact lens wearer uses the preservative solution for a long time, so that the contact lens preservative solution can be used for a long period of time. However, although the antibacterial effect of the antibacterial agent is exerted and the preservative solution can be used for a long time, the antibacterial agent is also simultaneously discharged from the container when the preservative solution is discharged. Therefore, there remains a problem in adding an antibacterial agent to a preservation solution. It should be noted that if no antibacterial agent is added, there is no problem of allergic disorder, but there is a problem in storing the preservation solution for a long period of time. From such a viewpoint, although a container for a contact lens preservative solution to which a disinfection filter is attached has been proposed,
The problem of allergic disorders has been pointed out when antibacterial agents are mixed. If the antibacterial agent is not mixed, even if a container for a contact lens preservation solution equipped with an antibacterial filter is used, the propagation of bacteria is unavoidable in the container, and there is a problem of contamination of various bacteria. However, a container equipped with a sterilization filter cannot be said to be sufficient, and further ones are desired.

[Disclosure of device]

A first object of the present invention is to provide a contact lens preservative solution which avoids the propagation of bacteria and substantially eliminates the problem of contamination by various bacteria. A second object of the present invention is to provide a contact lens preservative solution which does not cause the problem of allergic disorders even if an antibacterial agent is mixed in, in order to avoid the growth of bacteria. The object of the present invention comprises a container body, a sterilization filter provided at the outlet of the container body, and a water-insoluble antibacterial agent contained in the container body, and contains a water-insoluble antibacterial agent. The contact lens preservative solution is obtained by discharging the aqueous solution through the sterilization filter to the outside of the container body.

【Example】

FIG. 1 is a schematic view of one embodiment of a contact lens preservation solution manufacturing apparatus according to the present invention. In the figure, 1 is a container body made of plastic, 2 is a lid provided at the opening of the container body 1, 3 is a sterilization filter attached to the spout of the lid 2, and 4 is a water-insoluble antibacterial Agent 5 is water. The above-mentioned sterilization filter 3 is usually used for sterilization in 0.2 µm or 0.45
It is possible to remove bacteria, fungi or microorganisms such as amoeba, and inorganic or organic dust by using a material having a membrane pore of μm. The water-insoluble antibacterial agent 4 is in the form of fine particles, spheres, rods or porous particles, and metal ions such as silver ions, zinc ions and copper ions are exposed on the surface thereof. Ions suppress the growth of microorganisms. The water-insoluble antibacterial agent 4 having the above structure
Granules or tablets having a preservative solution for contact lenses are put in the container body 1, a certain amount of water is poured, and the side surface of the container body 1 is pressed, and a clean contact lens is sterilized through the sterilization filter 3. A stock solution is obtained. Therefore, the contact lens preservative solution thus obtained is kept clean because the growth of bacteria and the like due to the antibacterial agent is suppressed in the first place, and dead bodies of bacteria and foreign substances mixed during preparation are disinfected by the filter. It is a clean one removed by 3. Furthermore, antibacterial agent 4 added to suppress the growth of bacteria
Since it is water-insoluble, the antiseptic agent 4 is not contained in the contact lens preservative solution that has been removed by the sterilization filter 3 and has come out from the container body 1, and the problem of allergic disorder does not occur.

【effect】

The contact lens preservation solution manufacturing apparatus according to the present invention comprises a container body, a sterilization filter provided at an outlet of the container body, and a water-insoluble antibacterial agent contained in the container body. Since the contact lens preservative solution is obtained by discharging the aqueous solution containing the antibacterial agent from the container body through the sterilization filter, the contact lens preservative solution thus obtained is originally antibacterial. Growth of bacteria etc. is suppressed by the agent, it is kept clean, and dead bodies of bacteria and foreign substances mixed in during preparation are clean ones removed by a sterilization filter, and the growth of bacteria etc. is suppressed. Since the antibacterial agent added for this purpose is water-insoluble, it is removed by the sterilization filter, and the contact lens preservation solution that comes out of the container body is Not contain bacteriostatic agent, allergic disorders problems be those not occur, it has a feature that can be a problem on the health obtain very small contact lens storage solution.
