Abstract

The present invention discloses a nursing liquor for contact lenses and its production process. It is formed from 0.3-2% of cellulose, 0.2-2% of boric acid, 0.01%-1% of borax, 0.1%-2% of borneol and 93-98% of distilled water. It production process includes the following steps: firstly, dissolving borneol, heating distilled water to 85-90 deg.C, then dissolving cellulose, boric acid and borax in the heated distilled water, uniformly stirring them, then adding the borneol solution into the above-mentioned solution, disinfecting and cooling, and bottling so as to obtain the invented product.

Description

Contact lens care solution and production technology thereof

Technical field

The invention belongs to the nursing materials class, be applicable to before people wear contact lenses and splash into intraocular or drop in the lens inboard, can alleviate or eliminate the damage of contact lens, or eliminate the contact lens care solution that foreign matter stimulates symptoms such as caused eye is nervous, eye is dry and astringent cornea.

Background technology

The contact lens care solution of present domestic development mostly is cleaning, flushing, sterilization greatly and preserves the liquid of contact lens.In these liquid, most antiseptic and sanitizers that all contain some, and the use meeting for a long time of these materials produces within the eye and accumulates, and causes cornea to form other pathology.

Summary of the invention

Purpose of the present invention, mainly be to solve above-mentioned corrosion-proof and sterilization agent to harm that human body produced, improve vast contact lens wearers daily life quality, and provide safe in a kind of use, effective, comfortable, and can alleviate or eliminate the contact lens care solution of contact lens to the damage of cornea.

For realizing above-mentioned goal of the invention, this conditioning liquid is formed (content meter by weight percentage) by following component:

Cellulose 0.3%～2%; Boric acid 0.2～2%;

Borax 0.01%～1%; Borneol 0.1%～2%;

Distilled water 93～98%;

Its cellulose is: methylcellulose or Hydroxypropyl methylcellulose or carboxymethyl cellulose.

Cellulose: can effectively play lubricated, moisture-keeping function in the present invention.It is the glutinous albumen polymer substitute preferably in the human body tear.

Boric acid: the osmotic pressure of scalable solution, not only improved and reduced the shortcoming of viscosity, and alleviated the spread effect of solution to eye.This material can also release hydrogen ions enter cells of microorganisms inside in solution in addition, produces the bacteriostasis of certain energy.

Borax: mainly play and regulate pH value and antisepsis, in many antiseptics, boric acid and borax are used, and are comparatively desirable bacteriostatic agent in eye drops.

Borneol: play refrigerant to eye, lubricated comfortable effect.And also have clearing away heat to and alleviating pain, the inducing resuscitation effect of having one's ideas straightened out.

The processing step of producing contact lens care solution is as follows successively:

A), with borneol 0.1%～2% usefulness glycerine or dissolve with ethanol, borneol and glycerine or proportion of ethanol are 1: 0.5;

B), aforementioned proportion distilled water is heated 80～90 ℃, successively cellulose 0.3%～2%, boric acid 0.2～2%, borax 0.01%～1% joined in the distilled water, fully stirring; With borneol liquid, progressively join in the above-mentioned solution in the process that stir on the limit, after continuing fully to mix, in the airtight container of packing into, place after 24 hours flowing steam sterilization 30 minutes under the room temperature.

C), with above-mentioned sterilization cooled solution, in the aseptic eye drop bottle of packing into after the filtration.

The present invention compared with prior art beneficial effect is as follows:

1, this conditioning liquid prescription is reasonable, technology is simple, before wearing contact lenses, splashes into 1～2 of intraocular or eyeglass inboard, can prevent to produce bubble between eyes and the eyeglass, and form oxygen permeable layer.Can alleviate or eliminate of the damage of contact lenses sheet, or alleviate the intra-ocular foreign body excitement, keep the lubricated of cornea cornea; Non-contact lens wearers, the discomfort that because long-time excess eye-using, the eye that causes is dry and astringent, eye produced after kopiopia and bathing, the swimming.Drip in 1～2 of intraocular, can feel more comfortable salubrious.

2, the contact lenses sheet is immersed in this solution, do not find through detecting to observe as yet, this conditioning liquid produces chemistry and variation physics to contact lens, contrasts through soaking lens down with former existing soak solution, and it is fabulous to be smooth surface, pliability appropriateness, penetrability.With suitable dynamics tractive, flawless, the not damaged phenomenon takes place.

3, this product on probation through contact lens wearers and non-contact lens wearers all reaches the Expected Results of product design requirement, is subjected to user's favorable comment.

Embodiment

Embodiment 1

At first with borneol 1.% usefulness glycerine or dissolve with ethanol, between ratio be 1: 0.5; With 85 ℃ of distilled water 97% heating, successively Hydroxypropyl methylcellulose 0.5%, boric acid 1%, borax 0.5% are joined in the distilled water, fully stir; With borneol liquid, progressively join in the above-mentioned solution in the process that stir on the limit, after continuing fully to mix, in the airtight container of packing into, place after 24 hours flowing steam sterilization 30 minutes under the room temperature; With above-mentioned sterilization cooled solution, in the aseptic eye drop bottle of packing into after the filtration.

Embodiment 2

At first that borneol 0.5% usefulness is an amount of glycerine or dissolve with ethanol, between ratio be 1: 0.5; Distilled water 98% is suitably heated 88 ℃, successively methylcellulose 0.5%, boric acid 0.5% borax 0.5% are joined in the distilled water, fully stir; With borneol liquid, progressively join in the above-mentioned solution in the process that stir on the limit, after continuing fully to mix, in the airtight container of packing into, place after 24 hours flowing steam sterilization 30 minutes under the room temperature; With above-mentioned sterilization cooled solution, in the aseptic eye drop bottle of packing into after the filtration.

Points for attention:

1, when using this product, burning sensation is arranged, should stop using if splash into intraocular.Main cause wherein: (1), may be because improper storage for this product, liquid produces due to the chemical change in the eye drop bottle.(2), reach the special physique personnel of minority and may produce uncomfortable induction or allergic phenomena for this product.This kind situation can not produce damage to eye.

When 2, intraocular splashed into this product, bottleneck did not please touch eye, polluted in order to avoid produce.
