Description
Foreliggende oppfinnelse vedrører et rengjørings- og desinfiseringssystem for hårde og myke kontaktlinser, samt en fremgangsmåte for rengjøring og desinfisering med dette system. The present invention relates to a cleaning and disinfection system for hard and soft contact lenses, as well as a method for cleaning and disinfection with this system.
Kontaktlinser bæres direkte på øyets hornhinne. Øyets binde-hinnevæske inneholder i tillegg til anorganiske salter også tallrike organiske stoffer såsom proteiner og lipider. Disse stoffer lagrer seg ved lengre tids bæring på kontaktlinsen, Contact lenses are worn directly on the cornea of the eye. In addition to inorganic salts, the conjunctival fluid of the eye also contains numerous organic substances such as proteins and lipids. These substances are stored when the contact lens is worn for a long time,
og disse nedslagene hindrer sikten og kan også danne en nær-ingsbunn for bakterier, hvilke kan føre til øyeinfeksjoner. and these impacts obstruct vision and can also form a breeding ground for bacteria, which can lead to eye infections.
Det er derfor nødvendig å foreta en grundig rengjøring og desinfisering av kontaktlinser, i det minste en gang hver dag. Særlig må man da kunne nedbryte de avleirede proteiner, lipider, og myciner, slik at de kan fjernes ved hjelp av spyleløsninger. It is therefore necessary to carry out a thorough cleaning and disinfection of contact lenses, at least once every day. In particular, one must then be able to break down the deposited proteins, lipids and mycins, so that they can be removed using flushing solutions.
Rengjøringen av såkalte myke kontaktlinser er særlig kritisk, fordi det myke hydrofile materiale i linsen absorberer rengjør-ingsmiddelet og til og med bevirker en konsentrering av dette, med senere avlevering til øyet når kontaktlinsen er satt på plass. Kontaktlinsen kan på denne måten skades eller deform-eres, og ømfintlige vevavsnitt av hornhinnen kan også irri-teres og til og med beskadiges. The cleaning of so-called soft contact lenses is particularly critical, because the soft hydrophilic material in the lens absorbs the cleaning agent and even causes a concentration of this, with later delivery to the eye when the contact lens is put in place. In this way, the contact lens can be damaged or deformed, and sensitive tissue sections of the cornea can also be irritated and even damaged.
Det er derfor vanligvis ikke mulig å anvende rengjøringsmidler av den type som anvendes for hårde kontaktlinser, som har lite eller ikke absorberende flater. It is therefore usually not possible to use cleaning agents of the type used for hard contact lenses, which have little or no absorbent surfaces.
Fra DE-OS 24 17 844 er det kjent en fremgangsmåte til ren-gjøring av myke kontaktlinser. Kontaktlinsene legges i en iso-tonisk vandig løsning som inneholder en virksom proteasemengde. Som protease anvendes fortrinnsvis enzymet papain. Her skjer altså oppløsningen av de forstyrrende avleiringer ad enzymat-isk vei. From DE-OS 24 17 844 a method for cleaning soft contact lenses is known. The contact lenses are placed in an isotonic aqueous solution that contains an effective amount of protease. The enzyme papain is preferably used as protease. Here, the disturbing deposits are dissolved by enzymatic means.
I DE-OS 28 54 278 foreslås det å forbedre løsningsvirkningen til et rengjøringsmiddel som inneholder protease, derved at det tilsettes et ikke-ionogent befuktningsmiddel. Rengjørings-middelet skal foreligge i form av et pulver, som tablett eller som et flytende konsentrat, som forbrukeren kan løse opp i vann henholdsvis kan tynne ut med vann. In DE-OS 28 54 278 it is proposed to improve the dissolving effect of a cleaning agent containing protease, whereby a non-ionic wetting agent is added. The cleaning agent must be available in the form of a powder, as a tablet or as a liquid concentrate, which the consumer can dissolve in water or thin out with water.
Fra DE-PS 24 43 147 er det kjent en fremgangsmåte for rengjør-ing av kunststoff-kontaktlinser. Linsen som skal rengjøres behandles først med en basisk vandig løsning av en perforbindelse som avgir aktivt surstoff. Deretter bringes linsen inn i en sur vandig løsning av en perforbindelse som avgir aktivt surstoff. Linsen tas så ut av denne løsning, behandles med en ikke-ionisk detergent og spyles til slutt med vann. From DE-PS 24 43 147, a method for cleaning plastic contact lenses is known. The lens to be cleaned is first treated with a basic aqueous solution of a per-compound that emits active oxygen. The lens is then brought into an acidic aqueous solution of a percompound that emits active oxygen. The lens is then removed from this solution, treated with a non-ionic detergent and finally rinsed with water.
Denne fremgangsmåte er relativt komplisert, særlig fordi det er nødvendig å benytte tre ferdige løsninger. Fremgangsmåten har imidlertid den fordel at den kan anvendes både for myke og hårde kontaktlinser, selv om selve gjennomføringen vil være forskjellig, særlig med hensyn på tid og temperatur. This method is relatively complicated, particularly because it is necessary to use three ready-made solutions. However, the method has the advantage that it can be used for both soft and hard contact lenses, although the implementation itself will be different, particularly with regard to time and temperature.
Hensikten med foreliggende oppfinnelse er å tilveiebringe et rengjørings- og desinfiseringssystem for hårde og myke kontaktlinser, hvilket system på en sikker og rask måte medfører en fjerning av kontaktlinse-avleiringer, kan anvendes for alle typer kontaktlinser og dessuten ikke gir irritasjoner på øyet. The purpose of the present invention is to provide a cleaning and disinfection system for hard and soft contact lenses, which system safely and quickly removes contact lens deposits, can be used for all types of contact lenses and also does not cause irritation to the eye.
Dette oppnår man med et system som angitt i krav 1, med de i karakteristikken i krav 1 angitte trekk. This is achieved with a system as stated in claim 1, with the features stated in the characteristic in claim 1.
Patentkravene 2 og 3 angir stoffer som på særlig fordelaktig måte kan benyttes som reduksjonsmiddel i den i krav 1 angitte Patent claims 2 and 3 indicate substances which can be used in a particularly advantageous way as a reducing agent in the specified in claim 1
tablett B.tablet B.
Et eksempel for doseringen av de anvendte substanser er angitt i de respektive krav 4 og 5. Krav 6 vedrører en fordelaktig utforming av rengjøringsbeholderen, mens krav 7 gir et eksempel på hvordan rengjøringen kan gjennomføres. An example for the dosage of the substances used is given in the respective claims 4 and 5. Claim 6 relates to an advantageous design of the cleaning container, while claim 7 gives an example of how the cleaning can be carried out.
Ved rengjøringssystemet ifølge oppfinnelsen blir rengjørings-løsningene i hvert anvendelsestilfelle fremstilt i bruksøye-blikket. Anvendelsen av tabletter og den ferdige koksalt-løsning letter en slik fremstilling og medfører at man på en enkel måte kan få løsninger med nøyaktig like konsentrasjoner. With the cleaning system according to the invention, the cleaning solutions are prepared in each case of use at the moment of use. The use of tablets and the ready-made saline solution facilitates such preparation and means that solutions with exactly the same concentrations can be obtained in a simple way.
Anvendelsen av tabletter medfører den ytterligere fordel at rengjøringssystemet blir enkelt og sikkert å transportere, og at rengjøringssystemet alltid vil være optimalt virksomt. Dessuten blir forbruket så sparsomt som mulig. The use of tablets has the further advantage that the cleaning system will be easy and safe to transport, and that the cleaning system will always be optimally effective. In addition, consumption is as sparing as possible.
Tablett A tjener ifølge den i krav 4 angitte fremgangsmåte til fremstilling av de første løsning, som den tilsmussede kontaktlinse legges i. Det i denne tablett inneholdte urinstoffperoksohydrat kan betegnes som "fast vannstoffperoksyd", som utmerker seg ved en langt bedre holdbarhet enn den ferdige løsning har. According to the method specified in claim 4, tablet A is used for the preparation of the first solution, in which the soiled contact lens is placed. The urea peroxohydrate contained in this tablet can be described as "solid hydrogen peroxide", which is characterized by a far better shelf life than the finished solution hair.
Ved løsingen av tabeltt A i koksaltløsningen C fremkommer det en løsning som medfører en oksydativ spalting av proteiner, lipider og myciner og som dessuten, som følge av inne- When tablet A is dissolved in sodium chloride solution C, a solution is produced which causes an oxidative cleavage of proteins, lipids and mycins and which, moreover, as a result of
holdet av urinstoff, bevirker en spesifik avløsing av protein-komponenter fra kontaktlinsematerialet. the retention of urea causes a specific detachment of protein components from the contact lens material.
Kontaktlinsen blir etter den beskrevne første rengjørings-prosesslagt opp i en andre løsning. Denne andre løsning fremkommer ved å legge en tablett B i koksaltløsningen C. Den i tablett B ifølge krav 3 inneholdte L (+) ascorbinsyre (vitamin C) bevirker en rask reduktiv spalting av resterende vannstoffperoksyd. L (+) ascorbinsyre vil som et relativt lite molekyl trenge inn i kontaktlinsematerialet og ødelegge restene av vannstoffperoksyd. Denne virkningen av L (+) ascorbinsyre understøttes av at det ved oppløsingen av nc.triumbikarbona.t-andelen utvikles kulldioksyd, hvorved kontaktlinsen beveges på en skånsom måte i løsningen. After the first cleaning process described, the contact lens is placed in a second solution. This second solution is obtained by placing a tablet B in the sodium chloride solution C. The L (+) ascorbic acid (vitamin C) contained in tablet B according to claim 3 causes a rapid reductive cleavage of residual hydrogen peroxide. As a relatively small molecule, L (+) ascorbic acid will penetrate the contact lens material and destroy the remains of hydrogen peroxide. This effect of L (+) ascorbic acid is supported by the fact that carbon dioxide is developed during the dissolution of the triumbicarbonate portion, whereby the contact lens is moved in a gentle manner in the solution.
Den samme reduksjonsprosess oppnås ved anvendelsen av en tablett B som angitt i krav 2, idet man dog her ikke oppnår den nevnte "brusevirkning". I den andre løsning B/C blir altså The same reduction process is achieved by the use of a tablet B as stated in claim 2, although here the mentioned "shower effect" is not achieved. In the second solution B/C thus becomes
det resterende vannstoffperoksyd spaltet på en så fullstendig måte at senere irritasjoner av øyet utelukkes. Denne ned-brytingen skjer også i selve kontaktlinsematerialet, noe som er særlig viktig i forbindelse med myke kontaktlinser. the remaining hydrogen peroxide decomposed in such a complete way that later irritation of the eye is excluded. This breakdown also occurs in the contact lens material itself, which is particularly important in connection with soft contact lenses.
Den påfølgende lagring av kontaktlinsen i koksaltløsningen C bevirker en fullstendig avløsning av de nedbrutte avleirings-substanser, og linsen blir ekvilibrert. The subsequent storage of the contact lens in the sodium chloride solution C causes a complete detachment of the decomposed deposit substances, and the lens is equilibrated.
Oppfinnelsen skal forklares ytterligere under henvisning til tegningen som viser et utførelseseksempel av et rengjørings- The invention shall be further explained with reference to the drawing showing an exemplary embodiment of a cleaning
og desinfiserings-sett.and disinfection kit.
I tegningsfiguren er det vist et "brev" som er betegnet med 1 og som inneholder et antall tabletter A. Hver tablett ligger omhyllet av alu/PE-folie. Hver tablett består av 1 g urinstoffperoksohydrat. I "brev" 2 er det anordnet enkelttabletter B. Hver slik tablett består enten av en blanding av 0,1 til 0,5 g In the drawing, a "letter" is shown which is denoted by 1 and which contains a number of tablets A. Each tablet is wrapped in alu/PE foil. Each tablet consists of 1 g of urea peroxohydrate. In "letter" 2, single tablets B are arranged. Each such tablet consists either of a mixture of 0.1 to 0.5 g
L (+) ascorbinsyre (vitamin C) og 0,1 til 0,5 g natriumbikarbonat eller av 0,1 til 0,6 g natriumascorbat. I beholderen 3 er løsningen C plassert. Denne løsning C består av en konservert puffet 0,9%-koksaltløsning. 4 er en beholder som inneholder 10 ml opptil fyllestreken 5. Til denne beholder hører et lokk 6. Lokket 6 har som vist et fremspring 7 som er forsynt med en holder 8 for den kontaktlinse som skal rengjøres. L (+) ascorbic acid (vitamin C) and 0.1 to 0.5 g of sodium bicarbonate or of 0.1 to 0.6 g of sodium ascorbate. In container 3, solution C is placed. This solution C consists of a preserved puffed 0.9% saline solution. 4 is a container that contains 10 ml up to the fill line 5. This container includes a lid 6. As shown, the lid 6 has a projection 7 which is provided with a holder 8 for the contact lens to be cleaned.
For rengjøring blir den med 9 betegnede kontaktlinse lagtFor cleaning, the contact lens marked 9 is placed
inn i holderen 8. En tablett A legges i beholderen 4 og beholderen fylles opp til streken 5 med løsning C. Lokket 6 settes på og kontaktlinsen 9 holdes ca. 15 min i beholderen 4, idet man rister beholderen av og til. into the holder 8. A tablet A is placed in the container 4 and the container is filled to the line 5 with solution C. The lid 6 is put on and the contact lens 9 is held approx. 15 min in container 4, shaking the container occasionally.
Lokket 6 tas så av og løsningen A/C helles ut. DeretterLid 6 is then removed and the solution A/C is poured out. Then
fylles beholderen 4 opptil streken 5 med løsning C, en tablett B settes til, og lokket 6 legges på igjen. Ved anvendelse av en tablett som inneholder natriumbikarbonat sørges for at beholderen 5 ikke lukkes helt. Linsen 9 i holderen 8 holdes ca. the container 4 is filled up to the line 5 with solution C, a tablet B is added, and the lid 6 is put back on. When using a tablet containing sodium bicarbonate, ensure that the container 5 is not completely closed. The lens 9 in the holder 8 is held approx.
5 min. i løsningen B/C.5 min. in solution B/C.
Deretter helles løsningen ut og beholderen 4 fylles opp til streken 5 med løsning C. Lokket 6 skrus på og linsen oppbe-vares nå ca. 5 min. i løsningen C. The solution is then poured out and the container 4 is filled to the line 5 with solution C. The lid 6 is screwed on and the lens is now stored for approx. 5 min. in solution C.
Etter dette vil linsen 9 være rengjort og desinfisert og kan settes på plass på øyet etter uttak fra beholderen 8. After this, the lens 9 will be cleaned and disinfected and can be put back on the eye after removal from the container 8.
Det er også mulig å la linsen 9 være i holderen 8 etter at løs-ningen C er helt ut og legge linsen 9 på plass i beholderen 4, som fylles med en oppbevaringsløsning. It is also possible to leave the lens 9 in the holder 8 after the solution C is completely used up and place the lens 9 in place in the container 4, which is filled with a storage solution.
Av det forangående vil det gå frem at rengjørings- og des-infiseringsprosessen kan gjennomføres på en enkel og rask måte. Resultatet er en skikkelig behandlet kontaktlinse som kan settes på plass på øyet uten fare for irritasjoner. From the above, it will appear that the cleaning and disinfection process can be carried out in a simple and fast way. The result is a properly treated contact lens that can be placed on the eye without risk of irritation.
