Opfindelsen angår medicinske klæbemidler indeholdende syntetisk gummi, fyldstof og blødgøringsmiddel.The invention relates to medical adhesives containing synthetic rubber, filler and plasticizer.

Mere specielt angår den et klæbemiddel, som bl.a. kan anvendes til at fastklæbe hjælpemidler til en dyrekrop.More particularly, it relates to an adhesive which, among other things, can be used to adhere aids to an animal body.

5 Det er ofte nødvendigt, at tilvejebringe en klæ beforbindelse til en dyrekrop, sædvanligvis det menneskelige legeme, for at fastgøre et medicinsk hjælpemiddel eller apparat. Selv om der kendes mange klæbemidler, er meget få af disse egnede til anvendelse på menneske-10 hud. Kravene til et sådant klæbemiddel er strenge; det skal binde kraftigt til menneskehud, men dog kunne aftrækkes uden at beskadige hudoverfladen. Endvidere må det ikke give inflammation, selv ved langvarig kontakt, og det skal have en minimal tendens til at fremkalde 15 allergi. Det skal være uden indhold af ethvert stof, som kan være carcinogent. Kravet om at det ikke må fremkalde allergi er særligt vanskeligt at opfylde, og de fleste klæbemidler, som står til rådighed, har tendens til at fremkalde allergier hos en væsentlig del af patienterne.It is often necessary to provide an adhesive connection to an animal body, usually the human body, to attach a medical aid or apparatus. Although many adhesives are known, very few of these are suitable for use on human skin. The requirements for such an adhesive are strict; it must bind strongly to human skin, but could be pulled off without damaging the skin surface. Furthermore, it should not cause inflammation, even during prolonged contact, and it should have a minimal tendency to cause 15 allergies. It must be free from any substance which may be carcinogenic. The requirement that it should not cause allergies is particularly difficult to meet, and most of the available adhesives tend to cause allergies in a significant proportion of patients.

20 Når patienten har tendens til allergi, kan det være nødvendigt at prøve et antal klæbemidler, før der findes et, som er foreneligt. Dette er tidskrævende for lægen, og i mellemtiden er patienten udsat for ubehag som følge af allergiske reaktioner.20 When the patient is prone to allergies, it may be necessary to try a number of adhesives before finding one that is compatible. This is time-consuming for the physician, and in the meantime, the patient is exposed to discomfort due to allergic reactions.

25 Det er fra GB-patentskrift nr. 554.186 og nr.25 It is from GB Patent No. 554,186 and no.

585.184 almindelig kendt at anvende blandinger af syntetisk gummi, fyldstof, blødgøringsmiddel og harpiks som medicinske klæbemidler, og det er desuden almindelig kendt at anvende polyalkylacrylatharpikser i medicinske 30 lægemidler.585,184 are commonly known to use blends of synthetic rubber, filler, plasticizer and resin as medical adhesives, and additionally, it is well known to use polyalkyl acrylate resins in medical drugs.

Sådanne klæbemidler har imidlertid som nævnt vist sig at have tendens til at fremkalde allergi hos en væsentlig del af patienterne.However, as mentioned, such adhesives have been found to tend to cause allergies in a significant proportion of patients.

Fra US-patentskrift nr. 3.092.250 er det kendt at 35 fremstille trykfølsomme klæbemidler indeholdende chlore- 148403 2 ret gummi og acrylatesterpolymer. Disse klæbemidler anvendes til fremstilling af klæbebånd, der anvendes til tekniske formål f.eks. lyd- og vibrationsdæmpning i fly.From U.S. Patent No. 3,092,250, it is known to produce pressure-sensitive adhesives containing chlorinated rubber and acrylate ester polymer. These adhesives are used for making adhesive tapes used for technical purposes e.g. sound and vibration attenuation in aircraft.

Hensigten med opfindelsen er at angive et medi-5 cinsk klæbemiddel med "hvilket der opnås den fordel, at det ikke klæber under tilstedeværelse af vand, har en god vedhæftning og er fuldstændig fri for allergene virkninger.The object of the invention is to provide a medical adhesive having "the advantage of not adhering in the presence of water, having a good adhesion and being completely free of allergenic effects.

Dette opnås ifølge opfindelsen med et medicinsk 10 klæbemiddel indeholdende syntetisk gummi, fyldstof og blødgøringsmiddel, som er ejendommeligt ved, at det består a£ en geleret blanding af: a) 16 - 84 g polyethylmethacrylat, b) 100 ml butyl-phthalyl-butyl-glycollat eller 15 butyl— benzyl-phthalat, c) 6 - 16 g colloidt silica, og d) .16- 67 g chloreret polyisopren.This is achieved according to the invention with a medical adhesive containing synthetic rubber, filler and plasticizer which is characterized in that it consists of a gelled mixture of: a) 16 - 84 g of polyethyl methacrylate, b) 100 ml of butyl-phthalyl-butyl glycollate or butylbenzyl phthalate, c) 6-16 g of colloidal silica, and d) 16-67 g of chlorinated polyisoprene.

Polyethylmethacrylatet er et skørt fast stof, som fortrinsvis har en molekylvægt i området 50.000-20 1.000.000, mere foretrukket i området 100.000-500.000, f.eks. ca. 200.000.The polyethyl methacrylate is a brittle solid which preferably has a molecular weight in the range 50,000-20,000,000, more preferably in the range 100,000-500,000, e.g. ca. 200,000.

Butyl-phthalyl-butyl-glycollat eller butyl-ben-zyl-phthalat er en blødgøringskomponent. Denne er en væske, som er fysiologisk tålelig, og som tjener til at 25 blødgøre polyethylmethacrylatet. Butyl-phthalyl-butyl-glycollat og butylbenzylphthalat kan fås fra Monsanto som henholdsvis "Santicizer ® B16" og "Santicizer ® 160".Butyl-phthalyl-butyl-glycollate or butyl-benzyl-phthalate is a softening component. This is a physiologically tolerable liquid which serves to soften the polyethyl methacrylate. Butyl phthalyl butyl glycollate and butyl benzyl phthalate are available from Monsanto as "Santicizer ® B16" and "Santicizer ® 160" respectively.

Disse blødgøringsmidler er fysisk forenelige med 30 de andre komponenter i midlet og er fysiologisk tåleligt, herunder non-allergene.These plasticizers are physically compatible with the other components of the agent and are physiologically tolerable, including non-allergenic.

Colloidt silica er et indifferent partikkelfor-met fyldstof, der tjener til at stabilisere midlet i form af en sammenhængende gel. Fyldstoffet formindsker 35 også midlets klæbrighed, og mængden og arten af fyld- 148403 3 stoffet skal vælges, således at der frembringes den krævede grad af klæbrighed. Uden fyldstof er klæbningen meget kraftig, og adhesionen til den menneskelige hud er vanskelig at bryde uden at beskadige huden.Colloidal silica is an inert particulate filler which serves to stabilize the agent in the form of a coherent gel. The filler also reduces the tackiness of the agent, and the amount and nature of the filler must be selected so as to produce the required degree of tackiness. Without filler, the adhesive is very strong and the adhesion to the human skin is difficult to break without damaging the skin.

5 Den chlorerede polyisopren forbedrer klæbrigheden og sammenhængsevnen for midlet. Foretrukne chlorerede polyisopren-typer er kraftigt chlorerede polyisoprener såsom den højt chlorerede polyisopren, som fås fra Imperial Chemical Industries som "Alloprene® 20", 10 Mængden af de forskellige komponenter i midlet er pr. 100 ml butyl-phthalyl-butyl-glycollat eller bu-tyl-benzyl-phthalat ifølge opfindelsen som følger: Poly-ethylmethacrylat 16-84 g, fortrinsvis 20-45 g, silica 6-16 g, fortrinsvis 8-12 g, og chloreret gummi 16-67 g, 15 fortrinsvis 20-40 g. De relative forhold mellem mængderne skal indstilles inden for disse intervaller til opnåelse af produkter med de ønskede egenskaber. De optimale indbyrdes forhold til opnåelse af enhver specielt ønsket kombination af egenskaber kan bestemmes ved simple eks-20 perimenter.5 The chlorinated polyisoprene improves the tackiness and cohesiveness of the agent. Preferred chlorinated polyisoprene types are highly chlorinated polyisoprene, such as the highly chlorinated polyisoprene available from Imperial Chemical Industries as "Alloprene® 20". 100 ml of butyl-phthalyl-butyl-glycollate or butyl-benzyl-phthalate according to the invention as follows: Polyethylmethacrylate 16-84 g, preferably 20-45 g, silica 6-16 g, preferably 8-12 g, and chlorinated gums 16-67 g, 15 preferably 20-40 g. The relative proportions of the amounts must be adjusted within these ranges to obtain products having the desired properties. The optimum interrelationships for achieving any particularly desired combination of properties can be determined by simple experiments.

Midlet kan fremstilles ved at dispergere og opløse polyethylmethacrylatet, i pulverform, i blødgørings-midlet til dannelse af en gel. Fyldstoffet og det chlorerede gummi kan tilsættes på ethvert trin, fortrinsvis 25 medens viskositeten stadig er tilstrækkelig lav til at muliggøre en grundig blanding. Ved en foretrukken blandingsmetode blandes fyldstoffet med blødgøringsmidlet, hvorpå polyethylmethacrylatet tilsættes, hvorefter til slut det chlorerede gummi tilsættes.The agent can be prepared by dispersing and dissolving the polyethyl methacrylate, in powder form, in the plasticizer to form a gel. The filler and chlorinated rubber can be added at any stage, preferably while the viscosity is still low enough to allow a thorough mixing. In a preferred mixing method, the filler is mixed with the plasticizer to which the polyethyl methacrylate is added and finally the chlorinated rubber is added.

30 Blandingen er initialt en stiv pasta, som omdan nes til en homogen gel, når blødgøringsmidlet opløser polyethylmethacrylatet. Denne omdannelse forløber langsomt ved stuetemperatur og accelereres ved opvarmning, f.eks. til 40-80°C. Højere eller lavere temperaturer kan 35 anvendes, hvor dette er bekvemt. Ved 60°C kan omdannel- 4Initially, the mixture is a rigid paste which is converted to a homogeneous gel as the plasticizer dissolves the polyethyl methacrylate. This conversion proceeds slowly at room temperature and is accelerated by heating, e.g. to 40-80 ° C. Higher or lower temperatures can be used where convenient. At 60 ° C, conversion 4

sen typisk afsluttes i løbet af 4-5 timer. Omdannelsestiden afhænger i høj grad af, hvor findelt polyethyl-methacrylatet er. Fortrinsvis anvendes dette materiale i form af et pulver i området 50-400 mesh (britisk stan-5 dard sigte), fortrinsvis under 200 mesh.the latter typically ends in 4-5 hours. The conversion time depends to a large extent on how finely divided the polyethyl methacrylate is. Preferably, this material is used in the form of a powder in the range 50-400 mesh (British Standard Sieve), preferably below 200 mesh.

Efter omdannelsen er midlet en halvgennemsigtig flexibel gel med gummiagtig konsistens, og det føles klæbrigt. Det har god adhesion til menneskehud, men er let af trækkeligt. Materialet er stabilt, dvs. det for-10 bliver sammenhængende, flyder ikke ud, og det har stor koncentration af fyldstof og bevarer sin klæbrighed og adhesivitet efter langvarig lagring og anvendelse.After the transformation, the agent is a semi-transparent flexible gel with a rubbery texture and it feels sticky. It has good adhesion to human skin, but is easily removable. The material is stable, ie. it becomes cohesive, does not flow out, and has a high concentration of filler and retains its tackiness and adhesiveness after prolonged storage and use.

Det er ofte bekvemt at overføre midlet i geltilstand in situ på overfladen, som skal gøres klæbende.It is often convenient to transfer the gel in situ to the gel on the surface which must be made adhesive.

15 Alternativt kan midlet før omdannelsen udspredes på en overflade med et overtræk af et slipmiddel og overføres i geltilstand i form af et lag, som derpå kan lamineres på den artikel, der skal gøres klæbende. En anden måde at påføre midlet på er at danne en dispersion af midlet 20 i et organisk opløsningsmiddel, som opløser alle midlets komponenter bortset fra fyldstoffet, f.eks. et chloreret carbonhydrid, så som chloroform eller raethylendichlorid, påføre dispersionen på en genstand, som skal gøres klæbende, og afdampe opløsningsmidlet. Andre egnede opløs-25 ningsmidler er lavere aliphatiske ketoner, f.eks. acetone, aliphatiske ethere, f.eks. diethylether, og lavere alkanoler, f.eks. ethanol. Ofte vil man foretrække at undgå anvendelse af et opløsningsmiddel, da nogle patienter udviser allergiske reaktioner mod almindelige or-30 ganiske opløsningsmidler. Derfor kan det være fordelagtigt at udvalse midlet i pastaform til et tyndt lag mellem overflader med et som sliplag virkende overtræk, og påføre midlet på den genstand, som skal gøres klæbende, enten før eller efter omdannelse af blandingen til en 35 gel.Alternatively, prior to conversion, the agent may be spread on a surface of a release agent and transferred in a gel state in the form of a layer which may then be laminated to the article to be adhered. Another way of applying the agent is to form a dispersion of the agent 20 in an organic solvent which dissolves all the components of the agent except the filler, e.g. a chlorinated hydrocarbon, such as chloroform or ethylene dichloride, apply the dispersion to an article to be adhered and evaporate the solvent. Other suitable solvents are lower aliphatic ketones, e.g. acetone, aliphatic ethers, e.g. diethyl ether, and lower alkanols, e.g. ethanol. Often, it is preferred to avoid using a solvent, as some patients exhibit allergic reactions to common organic solvents. Therefore, it may be advantageous to select the agent in paste form into a thin layer between surfaces with a coating-acting coating and to apply the agent to the article to be adhered either before or after conversion of the mixture to a 35 gel.

148408 5148408 5

Midlet liar et bredt anvendelsesområde som klæbe-middel, specielt, men ikke udelukkende til anvendelse på menneskehud, f.eks. som klæbende overtræk på klæbebånd til kirurgisk anvendelse og andre medicinske og kirurgi-5 ske forbindinger, afdækninger og hjælpemidler. Et sådant kirurgisk klæbebånd eller forbinding vil omfatte et bøjeligt underlag, som bærer det omhandlede klæbemiddel på den ene flade. Substratet kan være et stof eller en formstoffilm, specielt en microporøs formstoffilm. Når 10 der kræves en forbinding med et aktivt medikament, kan et sådant inkorporeres i klæbemidlet. Eksempler på sådanne medikamenter omfatter antibiotika, antiseptika, kultjærederivater (som er af værdi ved visse dermatologiske lidelser) og antiinflammatoriske forbindelser, 15 f.eks. steroider. Sådanne forbindinger kan anvendes til at dække sår eller andre beskadigede hudområdser, f.eks. bensår såsom varikøse sår. Til sådanne anvendelser har klæbemidlet den fordel, at det ikke klæber under tilstedeværelse af vand. Hvis en forbindig derfor anvendes til 20 at dække et beskadiget eller væskende område af huden, vil den ikke klæbe til det beskadigede område, men vil kun klæbe til ubeskadiget hud rundt om dette.The agent has a wide application as an adhesive, especially but not exclusively for use on human skin, e.g. as adhesive coatings on adhesive tapes for surgical use and other medical and surgical dressings, covers and aids. Such a surgical adhesive bandage or bandage will comprise a flexible substrate which carries the present adhesive on one face. The substrate may be a substance or a plastic film, especially a microporous plastic film. When a compound with an active drug is required, such can be incorporated into the adhesive. Examples of such drugs include antibiotics, antiseptics, coal tar derivatives (which are valuable in certain dermatological disorders) and anti-inflammatory compounds, e.g. steroids. Such dressings can be used to cover wounds or other damaged skin areas, e.g. leg ulcers such as varicose ulcers. For such applications, the adhesive has the advantage of not sticking in the presence of water. Therefore, if a dressing is used to cover a damaged or fluid area of the skin, it will not adhere to the damaged area, but will only adhere to undamaged skin around it.

En særlig fordelagtig anvendelse for det omhandlede klæbemiddel er til fastgørelse af en ostomipose til 25 huden rundt om stoma på en patient. Efter en ostomiope-ration, f.eks. ileostomi, colostomi eller ureterostomi, har patienten en åbning, hvorigennem der sker en udtømning. Det udtømte opsamles i en pose, som udskiftes periodisk. Der har været betydelige vanskeligheder med 30 at sikre posens fastgørelse til patienten på en komfortabel men tæt måde.A particularly advantageous application of the present adhesive is to attach an ostomy bag to the skin around the stoma of a patient. After an ostomy operation, e.g. ileostomy, colostomy or ureterostomy, the patient has an opening through which a discharge occurs. The depleted is collected in a bag which is replaced periodically. There have been considerable difficulties in securing the bag's attachment to the patient in a comfortable but tight manner.

En anvendelse af klæbemidlet ifølge opfindelsen beskrives i det følgende under henvisning til tegningen, som illustrerer et klæbende element forsynet med klæbe-35 middel ifølge opfindelsen vist i tværsnit.An application of the adhesive according to the invention is described below with reference to the drawing, which illustrates an adhesive element provided with adhesive according to the invention shown in cross section.

148408 6 På tegningen betegner 1 underlivsvæggen hos en patient, som ved kirurgisk indgreb er forsynet med en stoma 2. Det klæbende element omfatter en skive 3 af formstof med en central åbning 4. Åbningen 4 er omgi-5 Vet af 2 koncentriske baner 5 og 6 som danner en rende, hvori findes en ring af karaya-gummi 7. Den ydre del af skiven er fastgjort til underlivs væggen med et lag klæbemiddel 8 ifølge opfindelsen med den nedenfor anførte sammensætning. Den anden flade 9 af skiven 10 står til rådighed til påklæbning af en pose passende til den udtømning, som skal opsamles.In the drawing, 1 denotes the abdominal wall of a patient, who is surgically fitted with a stoma 2. The adhesive member comprises a disc 3 of plastic with a central opening 4. The opening 4 is surrounded by 2 concentric webs 5 and 6 forming a gutter containing a ring of karaya rubber 7. The outer part of the disc is attached to the abdomen wall with a layer of adhesive 8 according to the invention with the composition given below. The second surface 9 of the disc 10 is provided for affixing a bag suitable for the discharge to be collected.

Adhesivet strækker sig noget ud over skiven 3 for herved at holde enheden i god kontakt med underlivsvæggen .The adhesive extends slightly beyond the disc 3 to keep the device in good contact with the abdominal wall.

15 Klæbemidlets sammensætning er f.eks. som følger, idet dele refererer til ml for såvidt angår væsker og til g for såvidt angår faste stoffer:The composition of the adhesive is e.g. as follows, parts referring to ml for liquids and g for solids:

Pastaen 5 blev derpå udvalset mellem to lag siliconeovertrukne papirark til en tykkelse på ca. 1,5 mm og henstillet til omdannelse i 6 timer i en ovn ved 60°C.First, the silica was mixed with butyl-phthalyl-butyl glycolate, and the polyethyl methacrylate and "Alloprene" were then added sequentially. A very viscous paste appeared which was mixed mechanically. The paste 5 was then rolled between two layers of silicone coated paper sheets to a thickness of approx. 1.5 mm and allowed to convert for 6 hours in an oven at 60 ° C.

Eksempel 2Example 2

En anden klæbemiddelsammensætning er som følger: 10 Butyl-benzyl-phthalat 6 mlAnother adhesive composition is as follows: 10 Butyl benzyl phthalate 6 ml

Polyethyl-methacrylat 2 g "Alloprene ® 20" 2 gPolyethyl methacrylate 2 g "Alloprene ® 20" 2 g

Colloid silica 0,5 gColloid silica 0.5 g

Polyethyl-methacrylatet var det samme som blev 15 anvendt i eksempel 1. Blande- og omdannelsesproceduren var også som i eksempel 1.The polyethyl methacrylate was the same as used in Example 1. The mixing and conversion procedure was also as in Example 1.

Eksempel 3Example 3

En tredie klæbemiddelsammensætning er som følger: Butyl-phthalyl-butyl-glycolat 100 ml 20 Polyethyl-methacrylat 42 g "Allopren ® " 33 gA third adhesive composition is as follows: Butyl phthalyl butyl glycolate 100 ml Polyethyl methacrylate 42 g Allopren® 33 g

Colloid silica 8 gColloid silica 8 g

Blande- og omdannelsesproceduren var også i dette tilfælde som i eksempel 1.The mixing and conversion procedure was also in this case as in Example 1.

25 Efter afkøling forelå klæbemidlerne i de tre ek sempler som et sammenhængende, særdeles klæbrigt lag, som kunne skæres i den ønskede størrelse og facon. Disse klæbemidler tåles særdeles godt af det menneskelige legeme. Faktisk er der ikke hidtil iagttaget nogen uheldig 30 reaktion over for dem selv hos patienter, som er allergiske over for mange sædvanlige medicinske klæbmidler.After cooling, the adhesives were present in the three samples as a coherent, highly adhesive layer that could be cut to the desired size and shape. These adhesives are extremely well tolerated by the human body. In fact, no adverse reaction has been observed so far to them even in patients who are allergic to many common medical adhesives.

Klæbemidlerne har gode flydeegenskaber, er som nævnt faste, men "flyder" alligevel godt ind i ar og hudfolder.The adhesives have good flow properties, as mentioned, are solid, but still "flow" well into scars and skin folds.
