DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye-washing sheet used for removing dust from eyes, preventing and removing eye oils, and cleaning eyes and surroundings of eyes. To a portable eyewash.

[0002]

2. Description of the Related Art The eye is an important information-gathering organ for humans.
It covers the corneal surface and maintains the optical function of the cornea, (2) flushes out foreign substances on the conjunctiva and corneal surface, (3) gives glucose and oxygen to the cornea, and (4) provides an antibacterial effect. But,
As urbanization progresses and the automobile society becomes everyday, various dusts are scattered in the atmosphere, making it difficult to protect eyes and maintain abilities by the natural self-cleaning action alone as described above. Various drugs, i.e., eye drops, have been frequently used in proportion to the number of drugs.

[0003] Eye drops are largely divided into (a) eye drops and (b)
Eye wash (eye lotion / eye wash), (c) eye ointment
t). All are sterile preparations because they are used for particularly sensitive eyes (especially cornea). (a) Eye drops are mainly used for treatment and diagnosis for the purpose of astringent (convulsion), sterilization, anti-inflammatory, mydriasis, miosis or local anesthesia. Depending on the form, it can be divided into aqueous or aqueous suspension ophthalmic solution and oily or oily suspension ophthalmic solution. Ordinarily, the eye drops are filled in a container in a liquid state. In order to prevent the tip of the container from being in contact with the eyelids and the like and being contaminated, the eye drops are used only at a certain height away from the eyes. The main component is methylcellulose. If the active ingredient is unstable in water, it is tabletted or powdered, and used again after mixing with the dissolution solution at the time of use.

(B) The eyewash is an aqueous solution of boric acid or sodium chloride (boric acid aqueous solution or physiological saline). Like ophthalmic solutions, since they are given directly to the eye, it is required that the osmotic pressure and pH be as close as possible to physiological conditions. It is mainly used for sterilization and cleaning of the eyes or surroundings of the eyes. (c) Ophthalmic ointment is a sterile ointment applied to the conjunctival sac, and is based on petrolatum or the like. Many contain bactericides, antibiotics, antihistamines, anti-inflammatory drugs, mydriatics, miotics and the like. It has the feature of long duration of efficacy because it stays locally for a long time.

[0005]

The residue that has dried on the secretions from the eyes and adhered to the margins of the eyelids and eyelashes is called eye oil. Secretions to the conjunctival sac include tears, oily fluids from the tarsal gland (my home gland) and the sebaceous glands of the lid margin, and mucin from the conjunctival goblet cells. About 25 of these secretions
% Evaporates from the exposed keratoconjunctiva, and the remaining solid content becomes eye oil. The properties of eye oils vary from liquid to solid, usually only slightly when they wake up, but with extraocular disease, tears increase due to release of lysozyme, which has an antibacterial effect, and Fat increases. In addition, even if the eyelid glands or sebaceous glands are inflamed, the amount of eye oil increases, and the use of eye drop ointment also increases the amount of eye oil.

[0006] In recent years, as described above, as the amount of dust flying in the atmosphere increases, a large amount of secretions, particularly tears, increases, and frequent generation of eye oils has come to be seen. For this reason, eye drops that have the effect of replacing tears are sometimes used, but many people simply rub the grease around the eyes with their hands or wipe them with a tissue, which is the most important thing. And unsanitary for the eye as a sensitive organ. What is generally referred to as eye drops is an aqueous ophthalmic solution, and its main purpose is to restore or improve eye functions such as removing eye fatigue and blurring. For this reason, there is no need to carry another eye drop, eyewash, or even eye ointment again to remove dust from the eyes or remove or prevent eye oils. He simply rubbed it with his hand and wiped it with a tissue.

Therefore, dust or grease is sanitarily wiped off,
At the same time, we developed a drug product in a form clearly different from conventional eye drops so that we can supply drugs to prevent the generation of eye oils. A study was made to make it easily portable with a highly usable usage form.

[0008]

As a result of the study, what has been developed comprises an eyewash sheet of a predetermined shape and size impregnated with a liquid eyewash and a sealable wrapper for accommodating the eyewash sheet. A portable eyewash device provided with an eyewash sheet taking-out opening in the bag so that the eyewash sheets can be taken out one by one from the package containing the eyewash sheets. In this portable eyewash device, a base sheet made of gauze, absorbent cotton, nonwoven fabric, woven fabric or paper impregnated with a liquid eyewash is used as an eyewash sheet. This portable eyewash will be referred to as "wet eyewash"
Call.

On the other hand, an eyewash sheet having a predetermined shape and size containing a water-soluble solid eyewash, and a wrapper for storing the eyewash sheet, wherein a plurality of eyewash sheets are stored. The eyewash sheet may be a portable eyewash device provided with an outlet for the eyewash sheet so that the eyewash sheet can be taken out one by one. In this portable eyewash device, a base sheet made of gauze, absorbent cotton, nonwoven fabric, woven fabric or paper containing a water-soluble solid eyewash is used as the eyewash sheet. This portable eyewash is hereinafter referred to as “dry eyewash”.

[0010] The portable eyewash of the present invention makes it possible to carry an eyewash sheet for removing eye oil in particular. From the viewpoint of hygiene, the used eyewash sheet is disposable, and therefore, the base sheet is made of gauze, absorbent cotton, nonwoven fabric, woven fabric or paper that is inexpensive, suitable for mass production, and can be discarded as a combustible material.
Each of the base sheets has water absorbency, and in a wet eyewash, the base sheet is impregnated with a ready-made liquid eyewash (boric acid water or physiological saline) to form an eyewash sheet (wet), which is sealed. By storing in a possible wrapper, it is possible to carry a plurality of eyewash sheets at all times. An example of a wrapping bag in a wet eyewash device is a wrapping bag made of a synthetic resin film or the like as seen in a pocket tissue and having an outlet formed by a fitting fastener. In this wet eyewash, the osmotic pressure of the liquid eyewash impregnated in the base sheet and the
Since the pH can be adjusted close to physiological conditions in advance, it has the advantage of enabling more effective eyewashing.

In the dry eyewash, since the same base sheet as that of the wet eyewash is used, and a water-soluble solid eyewash is contained to form the eyewash sheet (dry type), airtightness is provided in the wrapper for storing the eyewash sheet. Is not required. An eyewash sheet in a dry eyewash device is, for example, a liquid obtained by drying and powdering the above-mentioned liquid eyewash, and also including a base sheet impregnated with the liquid eyewash with only moisture removed and dried. Good. This eyewash sheet (dry type) is used by dissolving the solid eyewash in water by taking out (take out or soaking in water) water after taking out from the outlet of the wrapper.
This dry eyewash, unlike wet eyewashes, does not need to worry about drying of the eyewash sheet, is suitable for long-term carrying and storage, and of course it is cheaper because the opening of the wrapper can be a simple opening. There is an advantage that it can be manufactured.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a wet eyewash 1 of the present invention, and FIG. 2 is an eyewash sheet.
(Wet type) 3 is a flow chart showing the manufacturing process, FIG. 3 is a perspective view corresponding to FIG. 1 showing a state in which the eye wash sheets 3 are taken out one by one from the wrapper 2, and FIG. It is a use state reference drawing showing the state which wipes the eye 4 and the periphery of the eye 4 by using.

As shown in FIG. 1, the wet eyewash 1 of the present embodiment has a fitting fastener 5 as a take-out opening that can be sealed at the center.
An eyewash sheet 3 (FIG. 2)
10) are folded and stored, so that it has the appearance of a so-called pocket tissue and is easy to carry in a jacket pocket or bag.
As shown in FIG. 2, the eyewash sheet 3 is manufactured by impregnating a base sheet 6 obtained by cutting a polyester nonwoven fabric into a size of about 5 × 5 cm with a boric acid solution (liquid eyewash) 7. The impregnation of the base sheet 6 with the liquid eyewash 7 is performed, for example, by
Examples of the method include a method in which a base sheet is bundled and immersed in a pool of boric acid water or physiological saline, or a method in which the liquid eyewash is sprayed on a plurality of base sheets being transported on a conveyor. In addition, in this example, the eyewash sheet 3
Is folded as shown in FIG. 2 in order to compactly store it, but an eyewash sheet adapted to the planar shape of the wrapper may be laminated as it is.

Since the eyewash sheet 3 is impregnated with the boric acid solution 7, the zipper 2 is usually kept airtight by a fitting fastener 5 so as not to be dried. When using, please refer to Fig.
As shown in FIG. 2, the fitting fastener 5 is opened again, the eyewash sheets 3 are taken out one by one, and then the fitting fastener 5 is re-opened.
To close. As described above, since the wrapper 2 is always sealed, there is no possibility that the boric acid solution 7 oozes out of the eyewash sheet 3 and contaminates the pocket or the bag. As shown in FIG. 4, the taken out eyewash sheet 3 is, for example, held in a hand and traced along the eye 4 to wipe off dust and grease entering the eye 4 and clean the eye 4 and the periphery of the eye 4. Clean and disinfect. Since the used eyewash sheet 3 cannot be reused, it is simply discarded in a trash can.

FIG. 5 is a perspective view showing another example of the dry eyewash 6, FIG. 6 is a flowchart showing the manufacturing process of the eyewash sheet (dry) 10, and FIG. FIG. 4 is a use state reference diagram showing a state in which a water-soluble solid eyewash 12 that is contained is dissolved.

As shown in FIG. 5, the dry eyewash 8 of this embodiment is a polyethylene wrapping bag 9 having a perforation 13 in the center.
Further, like the above wet eyewash, the eyewash sheet 10 (see FIG. 2) is folded and accommodated in 10 sheets. Eyewash sheet 10,
As shown in FIG. 6, a base sheet 14 obtained by cutting a polyethylene open-cell foamed sheet into a size of about 5 × 10 cm contains boric acid (a water-soluble solid eyewash) 12. To manufacture. Solid eyewash 12 on base sheet 14
The inclusion of, for example, a method of drying a base sheet impregnated with boric acid water or physiological saline, or a method of dipping the base sheet in the powder of the solid eyewash and spraying. it can. The eyewash sheet 10 of the present embodiment may be folded as shown in FIG. 2 or an eyewash sheet adapted to the planar shape of the wrapper may be laminated as it is.

Since the eyewash sheet 10 only contains boric acid 12, it is not necessary to strictly maintain the airtightness of the wrapping bag 9. Therefore, in the wrapping bag 9 of this example, if the outlet is formed by breaking the perforation 13, the outlet is kept open. In use, the eyewash sheet 10 taken out of the opening of the wrapper 9 is, as shown in FIG.
For example, boric acid 12 is dissolved by applying tap water 11,
The eyewash sheet 10 impregnated with the boric acid water 7 is made on the spot. Thus, the eyewash sheet 10 impregnated with the boric acid water 7
Can be used similarly to the eyewash sheet 3 of the above-mentioned wet eyewash 1 (see FIG. 4), and can be discarded in a trash can after use. When using the eyewash sheet 10 of this example, water is essential, but in reality, water supply is found everywhere in public places, so there is no particular inconvenience, rather, rather than worry about drying of the eyewash sheet 10. There is the advantage that it is not necessary.

The shape of the eyewash sheet is not limited as long as the size of the eyewash sheet is small when it is carried in consideration of portability as a portable eyewash. As in the above example, the eyewash sheet 3 larger than the wrapper 2 is folded to the size of the wrapper (see FIG. 2), or as described above, the eyewash sheets approximately equal in size to the wrapper are laminated. It may be. As shown in FIG. 8, a long eyewash sheet 15 having a width substantially equal to that of the wrapper is folded at the length of the wrapper, and the fold line is perforated.
As 16, it may be cut at the perforation 16 when taking out from the wrapper. In this example, if necessary, the eyewash sheet 15 can be separated and used at a predetermined length, and the size (in particular, the length) can be used such that two sheets or three sheets can be collectively separated and used. It has usage characteristics that can be freely selected.

[0019]

The portable eyewash of the present invention can provide a simple eye drop which can be carried and used as if it were a pocket tissue. In particular, for portable eyewashes that wash the eyes and the area around the eyes with the primary purpose of wiping dust and grease, the basic chemicals, boric acid or sodium chloride (boric acid solution or saline), are available at low cost. It is easy to manufacture base sheets and wrappers, and can be produced very cheaply and in large quantities, making it a very convenient product as a disposable eyewash. Thus, the portable eyewash of the present invention has one aspect as a product that is easy to provide.

In the past, the back of the hand was used to get dust into the eyes and wipe off the greasy eyes, but this is obviously unsanitary. INDUSTRIAL APPLICABILITY The portable eyewash of the present invention not only removes dust and grease in a sanitary manner but also functions to clean the eyes and the periphery of the eyes. Further, depending on the eyewash impregnated or contained in the eyewash sheet, generation of eye oil can be further prevented. Such eye drops as portable eye washers can be easily taken out and sanitized to clean eyes even in public places where use in the city is refrained like conventional eye drops. It has the convenience of use regardless of the use (eye drops must face up).
