Description

[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. An object of the present invention is to provide a container body, a filter, and an adsorbent that adsorbs an antibacterial agent, and to put an aqueous solution containing the antibacterial agent in the container body through the adsorbent and the filter. A contact lens preservative solution is obtained by discharging the contact lens preservative solution to the outside.

【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 sterilization filter 3. Is a nozzle (passage) on the tip side of the adsorbent 4, and 6 is water. The adsorbent 4 is for adsorbing an antibacterial agent such as a preservative. For example, if the antibacterial agent is benzalkonium chloride, a cation exchanger is used as the adsorbent (adsorbent). Further, the above-mentioned sterilizing filter 3 is usually used for sterilizing in 0.2 μm or 0.45 μm in pharmaceutical production.
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. Then, in the above-mentioned constitution, granules or tablets having an antibacterial agent (water-soluble) such as benzalkonium chloride or a preservative solution for contact lenses are put in the container body 1, and a certain amount of water is poured to the container body 1. When the side surface is pressed, a clean contact lens preservative solution that has been adsorbed and sterilized through the adsorbent 4 and the sterilization filter 3 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, the antibacterial agent added to suppress the growth of bacteria and the like is removed by the adsorbent 4, and the contact lens preservative solution that has come out of the container body 1 does not contain the antibacterial agent, causing the problem of allergic disorders. Absent. Further, since the nozzle 5 is present on the tip side of the adsorbent 4, even if the movement of water due to thermal movement or the like occurs in the container body 1 during storage, it is difficult for water to enter the nozzle 5. The antibacterial agent such as the antiseptic agent in the container body 1 is hard to be captured by the adsorbent 4, and therefore, the antibacterial agent is effectively dispersed in the water in the container body 1 and has good storability. Furthermore, since the antibacterial agent such as the preservative is rarely trapped by the adsorbent 4 insignificantly, the adsorbent 4 need not be frequently replaced.

【effect】

An apparatus for producing a contact lens preservation solution according to the present invention comprises a container body, a filter, and an adsorbent for adsorbing an antibacterial agent, and the aqueous solution containing the antibacterial agent contained in the container body is used for the adsorbent and the filter. The contact lens preservative solution can be obtained by discharging it to the outside of the container body through the contact lens preservative solution. Kept clean, and the carcasses of bacteria and foreign substances mixed in during preparation were removed by a sterilization filter, and the antibacterial agent added to suppress the growth of bacteria was removed by an adsorbent. The antiseptic agent is not contained in the contact lens preservative solution that has come out of the container body, and the problem of allergic disorder does not occur. Having features that can be a problem on obtaining a very small contact lens storage solution.
