Den foreliggende opfindelse angår en klæbende hudplade til at fastgøre en stomi-pose til huden af en stomipatient, idet hudpladen omfatter en fleksibel plade, som omfatter et lag af et hudvenligt klæbmiddel og har en åbning til optagelse af en stoma af patienten, en ringformet koblingsring med en indre og en ydre periferi og ind-5 rettet til udløseligt at indgribe med et tilsvarende koblingsorgan af stomiposen, idet koblingsringen er fastgjort til den fleksible plade med koblingsringens plan hovedsagelig parallelt med planet af den fleksible plade og hovedsagelig koncentrisk med åbningen til optagelse af stomaen, og et filter til at deodorisere flatusgas eller tarmluft.The present invention relates to an adhesive skin plate for attaching an ostomy bag to the skin of an ostomy patient, the skin plate comprising a flexible plate comprising a layer of a skin-friendly adhesive and having an opening for receiving a stoma of the patient, an annular coupling ring with an inner and an outer periphery and arranged to releasably engage with a corresponding coupling member of the ostomy bag, the coupling ring being attached to the flexible plate with the plane of the coupling ring substantially parallel to the plane of the flexible plate and mainly concentric with the opening for receiving the the stoma, and a filter to deodorize flatus gas or intestinal air.

Da deodorisingsfilteret er forholdsvis dyrt, er det ønskeligt at genbruge filteret i forbindelse med flere på hinanden følgende bortsmidelige stomiposer ved at fastgøre filteret til hud pladen i stedet for til stomiposen således, at filteret ikke bortsmides sammen med den fyldte stomipose.Since the deodorizing filter is relatively expensive, it is desirable to reuse the filter for several consecutive removable ostomy bags by attaching the filter to the skin plate rather than to the ostomy bag so that the filter is not removed together with the filled ostomy bag.

15 US patent nr. 4.232.672 beskriver en hudplade af den omhandlede type, hvor koblingsringen er forsynet med et sideværts fremspring, som omfatter et filterkammer, der indeholder filtre, som står i forbindelse med to flatusgaspassager, som strækker sig gennem koblingsringen til den indre periferi heraf. Manuelt betjenelige ventil- 20 organer tillader, at flatusgassen strømmer gennem passagerne og gennem filtrene.U.S. Patent No. 4,232,672 discloses a skin plate of the type in which the coupling ring is provided with a lateral projection comprising a filter chamber containing filters communicating with two flatus gas passages extending through the coupling ring to the inner periphery thereof. Manually operated valve means allow the flatus gas to flow through the passages and through the filters.

Dette er en relativt kompliceret og dyr konstruktion, som kræver manuel aktivitet for at udlufte flatusgassen. Dimensionen af koblingsringen vinkelret på dennes plan er også forholdsvis stor for at rumme udluftningsmekanismen, og hudpladen er således relativt fyldig, hvilket er uønskeligt.This is a relatively complicated and expensive construction that requires manual activity to vent the flatus gas. The dimension of the coupling ring perpendicular to its plane is also relatively large to accommodate the vent mechanism and thus the skin plate is relatively full, which is undesirable.

25 US patent nr. 4.826.495 beskriver også en hudplade af den omhandlede type med en relativt tyk holdeplade, som har et ringformet fremspring, som indeholder en ringformet kanal, som står i forbindelse med det indre af en stomipose fastgjort til koblingsringen gennem flatusgasindløbsåbningerne i det ringformede fremspring.U.S. Patent No. 4,826,495 also discloses a skin plate of the type with a relatively thick holding plate having an annular projection containing an annular channel communicating with the interior of an ostomy bag attached to the coupling ring through the flatus gas inlet openings in the the annular projection.

30 Den ringformede kanal står i forbindelse med et filter, som er anbragt i en udsparing tilvejebragt i legemet af holdepladen. Dette er også en forholdsvis dyr og kompliceret konstruktion, som også er forholdsvis fyldig.The annular channel communicates with a filter arranged in a recess provided in the body of the retaining plate. This is also a relatively expensive and complicated construction, which is also relatively full.

Det er et hovedformål med opfindelsen at tilvejebringe en klæbende hud plade med et integreret flatusgasdeodoriseringsfilter, som er forholdsvis enkel at fremstille, er forholdvis billig og har en forholdsvis lille maksimumsdimension vinkelret på planet af koblingsringen, således at hele hudpladen ikke er uhensigtsmæssigt fyldig (lav-5 profil).It is a principal object of the invention to provide an adhesive skin plate with an integral flatus gas deodorization filter which is relatively simple to manufacture, is relatively inexpensive and has a relatively small maximum dimension perpendicular to the plane of the coupling ring so that the entire skin plate is not inappropriately full (low 5 profile).

Ifølge opfindelsen opnås dette formål ved at tilvejebringe en eller flere flatusgas-passager, som strækker sig mellem koblingsringen og den fleksible plade fra den indre periferi til den ydre periferi og gennem filteret, og et rum, som har en ydre del, 10 som er anbragt uden for den ydre periferi, og en indre del, som er anbragt mellem koblingsringen og den fleksible plade, idet et flatusgasudløb er tilvejebragt i en væg af den ydre del, idet rummet udgør en del af flatusgaspassagen, og filteret er anbragt inden i rummet, således atflatusgasudløbet spærres af filteret.According to the invention, this object is achieved by providing one or more flatus gas passages extending between the coupling ring and the flexible plate from the inner periphery to the outer periphery and through the filter, and a compartment having an outer portion 10 disposed therein. outside the outer periphery, and an inner portion disposed between the coupling ring and the flexible plate, a flatus gas outlet being provided in a wall of the outer portion, the compartment forming part of the flatus gas passage, and the filter being disposed within the compartment, so that the outlet gas outlet is blocked by the filter.

15 Herved tilvejebringes der et flatusgasfilterhus uden at kræve fyldige og dyre modifikationer af koblingsringen.Hereby, a flat gas filter housing is provided without requiring full and expensive modifications of the coupling ring.

Ved den for tiden foretrukne udførelsesform af en hudplade ifølge opfindelsen defineres den ydre del af rummet af en første filmstrimmel af plastmateriale, fortrinsvis 20 indrettet til at definere en pung.In the presently preferred embodiment of a skin plate according to the invention, the outer part of the compartment is defined by a first film strip of plastic material, preferably 20 adapted to define a purse.

Herved tilvejebringes der et særligt billigt filterhus, som har en lav profil og let kan fremstilles og med små pladskrav.This provides a particularly inexpensive filter housing, which has a low profile and can be easily manufactured and with small space requirements.

25 Ved et andet aspekt angår den foreliggende opfindelse en klæbende hudplade til at ~ fastgøre en stomipose til huden af en stomipatient, idet hudpladen omfatter en fleksibel plade, som omfatter et lag af et hudvenligt klæbemiddel og har en åbning til optagelse af en stoma af patienten, en koblingsring, som har en indre og en ydre periferi og er indrettet til udløseligt at indgribe med et tilsvarende koblingsorgan af 30 stomiposen, idet koblingsringen er fastgjort til den fleksible plade med planet af koblingsringen hovedsagelig parallel med planet af den fleksible plade og generelt koncentrisk med åbningen til optagelse af stomaen, et filter til deodorisering af flatus-gas, et flatusgasudluftningsrum i form af en pung eller en pose og fremstillet af en I- ---- DK 176079 B1 første film af et plastmateriale og forløbende udad forbi den ydre periferi, idet den første film er forsynet med en flatusgasudløbsåbning, og en flatusgaspassage, som strækker sig fra den indre periferi til det indre af udluftningspungen og gennem både filteret og filatusgasudløbsåbningen, idet filteret er anbragt således, at i hovedsagen \ 5 al flatusgassen udluftet gennem flatusgasåbningen strømmer gennem filteret.In another aspect, the present invention relates to an adhesive skin plate for attaching an ostomy bag to the skin of an ostomy patient, the skin plate comprising a flexible plate comprising a layer of a skin-friendly adhesive and having an opening for receiving a stoma of the patient. , a coupling ring having an inner and an outer periphery and adapted to releasably engage with a corresponding coupling member of the ostomy bag, the coupling ring being attached to the flexible plate with the plane of the coupling ring substantially parallel to the plane of the flexible plate and generally concentrically with the opening for receiving the stoma, a filter for deodorizing flatus gas, a flatus gas venting chamber in the form of a purse or a bag and made of an I----- DK 176079 B1 first film of a plastic material and extending outwardly beyond the outer periphery, the first film being provided with a flatus gas outlet orifice and a flatus gas passage extending from the inner periphery to the interior of the vent bag and through both the filter and the filatus gas outlet opening, the filter being arranged such that substantially all the flatus gas vented through the flatus gas opening flows through the filter.

Herved tilvejebringes der en enkel og billig hudplade med integreret filter og med lav profil.This provides a simple and inexpensive skin plate with integrated filter and low profile.

10 Flatusgaspassagen kan strække sig mellem koblingsringen og den fleksible plade, eller den kan strække sig i det mindste delvis gennem en kanal, som strækker sig gennem en del af koblingsringen fra et kanalindløb til et kanaludløb.The flatus gas passage may extend between the coupling ring and the flexible plate, or it may extend at least partially through a duct extending through a portion of the coupling ring from a duct inlet to a duct outlet.

I dette sidste tilfælde kan en kant af pungen være fastgjort til en mod legemet ven-15 dende eller proksimal flade af koblingsringen vendende mod den fleksible plade, og den modstående kant af pungen kan være fastgjort til en distal flade af koblingsringen vendende bort fra den fleksible plade, idet kanaludløbet er placeret mellem den proksimale og den distale flade, således at flatusgas, som træder ud af kanalen, trænger ind i pungen.In this latter case, an edge of the purse may be attached to a body facing or proximal face of the coupling ring facing the flexible plate, and the opposite edge of the purse may be attached to a distal surface of the coupling ring facing away from the flexible plate, the channel outlet being positioned between the proximal and the distal surface so that flatus gas exiting the channel enters the scrotum.

15 På tegningerne henvises der til lignende elementer ved forskellige udførelsesformer ved hjælp af de samme henvisningstal.15 In the drawings, reference is made to similar elements in different embodiments by the same reference numerals.

Der henvises til alle udførelsesformerne af en hudplade ifølge opfindelsen ved 20 hjælp af tallet 1, og de omfatter et lag 2 af et trykfølsomt, hudvenligt klæbemiddel.Reference is made to all embodiments of a skin plate according to the invention by the number 1 and comprises a layer 2 of a pressure-sensitive, skin-friendly adhesive.

Klæbemiddellaget 2 kan være dannet af ethvert passende trykfølsomt klæbemiddel, som i almindelighed anvendes til at fastgøre hudplader af stomiindretninger til de peristomale hudflader af en bruger. F.eks. kan der anvendes et hypoallergent 25 acrylisk klæbemiddel af medicinsk kvalitet. Det er imidlertid at foretrække, at klæbemiddellaget dannes af et blødt, hudvenligt klæbende materiale, som indeholder hydrokolloid og er i stand til at absorbere fugtighed og er klæbende både i våd og tør tilstand. Et sådant materiale kaldes i almindelighed en hudbarrieresammen-sætning og omfatter typisk en kontinuerlig elastomerklæbemiddelfase, som har 30 hydrokolloidpartikler dispergeret overalt i den kontinuerlige fase. Den initiale klæbeevne, som normalt refereres til som værende "tør klæbeevne", tilvejebringes af den kontinuerlige fase, men, da sådan en sammensætning er okklusiv eller ikke-gasgennemtrængelig (non-breathable), vil klæbning til huden afbrydes af sved og DK 176079 B1 væskeformig stomaudflåd, hvis det ikke var for de dispergerede hydrokolloider, som absorberer væsker og derved vedligeholder og muligvis forbedrer den klæbende fastgørelse til huden. US patent nr. 4.551.490 og andre referencer beskriver, at passende vandabsorberende og vandkvælbare hydrokolloidharpikser kan inkludere 5 natriumcarboxymethylcellulose, pektin, gelatine, guarharpiks, johannesbrødharpiks og lignende. Elastomererne anvendt i den kontinuerlige fase kan være polyisobuty-len, naturgummi, siliconegummi, acrylonitrilgummi og andre elastomerer kendt inden for det tekniske område for at have lignende egenskaber.The adhesive layer 2 may be formed by any suitable pressure-sensitive adhesive which is generally used to attach oblique skin plates to the peristomal skin surfaces of a user. Eg. a hypoallergenic medical grade acrylic adhesive can be used. However, it is preferable that the adhesive layer be formed from a soft, skin-friendly adhesive material which contains hydrocolloid and is capable of absorbing moisture and is both wet and dry in adhesive. Such a material is generally called a skin barrier composition and typically comprises a continuous elastomer adhesive phase having 30 hydrocolloid particles dispersed throughout the continuous phase. The initial adhesiveness, usually referred to as being "dry adhesive", is provided by the continuous phase, but since such a composition is occlusive or non-breathable, adhesion to the skin will be interrupted by sweat and DK 176079 B1 liquid stoma effluent if it were not for the dispersed hydrocolloids which absorb fluids and thereby maintain and possibly improve the adhesive attachment to the skin. U.S. Patent No. 4,551,490 and other references disclose that suitable water-absorbing and water-swellable hydrocolloid resins may include sodium carboxymethyl cellulose, pectin, gelatin, guar resin, locust bean resin and the like. The elastomers used in the continuous phase may be polyisobutylene, natural rubber, silicone rubber, acrylonitrile rubber and other elastomers known in the art to have similar properties.

10 Et siliconebehandlet slipark 3 af plastmateriale påføres den mod legemet vendende eller proksimale flade af klæbemiddellaget 2 til at beskytte klæbemiddellaget 2, indtil hudpladen skal påføres huden af en bruger deraf.A silicone-treated release sheet 3 of plastic material is applied to the body-facing or proximal surface of the adhesive layer 2 to protect the adhesive layer 2 until the skin plate is applied to the skin by a user thereof.

" En bærefolie 4 af varmeforsegleligt plastmateriale er fastgjort til den distale flade af 15 klæbemiddellaget 2. En åbning 5 til optagelse af en stoma af en bruger af hudpladen er tilvejebragt i laget 2 og i arkene 3 og 4."A heat-sealable plastic carrier 4 is attached to the distal surface of the adhesive layer 2. An aperture 5 for accommodating a stoma by a user of the skin plate is provided in the layer 2 and in sheets 3 and 4.

En koblingsring 6 af et fleksibelt plastmateriale og med en ydre periferi 7 og en indre periferi 8 er indrettet til at indgribe med en tilsvarende koblingsring på en ikke vist 20 stomipose til at fastgøre posen til brugeren, således at stomamateriale kan samles i posen, når hudpladen 1 med posen fastgjort til hudpladen klæbes til den peristo-male hud af brugeren.A coupling ring 6 of a flexible plastic material and having an outer periphery 7 and an inner periphery 8 is arranged to engage with a corresponding coupling ring on an ostomy bag (not shown) to secure the bag to the user, so that the ostomy material can be collected in the bag when the skin plate 1 with the bag attached to the skin plate is adhered to the peristomal skin by the user.

Under henvisning til fig. 1-2 er koblingsringen 6 fastgjort til klæbemiddellaget 2 ved 25 hjælp af en første ringformet strimmel 9 af film af et varmeforsegleligt plastmateriale med en kant 10 fastgjort ved varmeforsegling til en kant 11 af en anden ringformet strimmel 12 af film af et varmeforsegleligt plastmateriale, hvilken kant 11 igen er fastgjort til bærefolien 4 ved varmeforsegling. Koblingsringen 6 er fastgjort til filmstrimlen 9 ved 13 ved varmeforsegling, hvorved koblingsringen 6 er fleksibelt fast-30 gjort til klæbemiddellaget 2.Referring to FIG. 1-2, the coupling ring 6 is attached to the adhesive layer 2 by a first annular strip 9 of film of a heat sealable plastic material with an edge 10 attached by heat seal to an edge 11 of a second annular strip 12 of film of a heat sealable plastic material which edge 11 is again attached to the carrier foil 4 by heat sealing. The coupling ring 6 is attached to the film strip 9 at 13 by heat sealing, whereby the coupling ring 6 is flexibly attached to the adhesive layer 2.

Kanterne 14 og 15 af strimlerne hhv. 9 og 12 modsat kanterne hhv. 10 og 11 er varmeforseglet til hinanden, således at der dannes et ringformet rum eller kammer DK 176079 B1 16, som har en indre del 16a placeret mellem koblingsringen 6 og klæbemiddellaget 2 og en ydre del 16b i form af en pung placeret uden for den ydre periferi 7 af koblingsringen 6. Filmstrimlerne 9 og 12 kan være i ét stykke, således at varmefor-seglingen af kanterne 14 og 15 kan undgås.The edges 14 and 15 of the strips, respectively. 9 and 12 opposite the edges, respectively. 10 and 11 are heat sealed to each other so as to form an annular space or chamber DK 176079 B1 16 which has an inner portion 16a located between the coupling ring 6 and the adhesive layer 2 and an outer portion 16b in the form of a purse located outside the outer periphery 7 of the coupling ring 6. The film strips 9 and 12 may be integral so that the heat sealing of the edges 14 and 15 can be avoided.

Et flatusgasdeodoriseringsfilter 17 er anbragt i den ydre del 16b af rummet 16 og er klæbet til filmstrimlen 12, således at det dækker en flatusgasudløbsåbning 18 tilvejebragt i filmstrimmel 12. To flatusgasindløbsåbninger 19 og 20 anbragt med indbyrdes afstand er tilvejebragt i den del af filmstrimlen 9, som er placeret inden for 10 den indre periferi 8 af koblingsringen 6. Indløbsåbningerne 19 og 20 er placeret fjernt fra udløbsgasåbningen 18. Indløbsåbningerne 19 og 20 laves ved at skære et krydsformet snit i filmstrimlen 9.A flatus gas deodorization filter 17 is disposed in the outer portion 16b of the space 16 and is adhered to the film strip 12 to cover a flatus gas outlet opening 18 provided in film strip 12. Two flatus gas inlet openings 19 and 20 are provided in that portion of film strip which is located within 10 the inner periphery 8 of the coupling ring 6. The inlet openings 19 and 20 are located distant from the outlet gas opening 18. The inlet openings 19 and 20 are made by cutting a cross-shaped section in the film strip 9.

Under brugen fjernes sliparket 3 fra klæbemiddellaget 2, og den proksimale flade af 15 laget 2 påføres den peristomale hud af en bruger, således at stomaen optages i åbningen 5. En opsamlingsstomipose fastgøres dernæst til hudpladen 1 ved at bringe koblingsringen af posen i indgreb med den tilsvarende koblingsring 13.During use, the release sheet 3 is removed from the adhesive layer 2 and the proximal surface of the layer 2 is applied to the peristomal skin of a user so that the stoma is accommodated in the opening 5. A collecting ostomy bag is then attached to the skin plate 1 by engaging the coupling ring of the bag with the corresponding coupling ring 13.

Stomamateriale bestående af fast materiale, væske og flatusgas ledes dernæst fra 20 stomaen ind i opsamlingsposen. Det faste materiale og væsken falder ned i posen, medens flatusgas ledes ud af posen gennem flatusgaspassagerne defineret af indløbsåbningerne 19 og 20, den indre rumdel 16a og den ydre rumdel 16b, filteret 17 og flatusgasudløbet 18. Strømmen af flatusgas er vist ved hjælp af pile.Stoma material consisting of solid material, liquid and flatus gas is then fed from the stoma into the collection bag. The solid material and liquid fall into the bag while the flatus gas is discharged from the bag through the flatus gas passages defined by the inlet openings 19 and 20, the inner compartment 16a and the outer compartment 16b, the filter 17 and the flatus gas outlet 18. The flow of flatus gas is shown by arrows. .

Filteret 17 er af typen beskrevet i US patent nr. 6.506.184 inkorporeret heri ved 25 henvisning. En hvilken som helst anden type deodoriserende filter kan imidlertid anvendes.Filter 17 is of the type disclosed in US Patent No. 6,506,184 incorporated herein by reference. However, any other type of deodorizing filter can be used.

I denne udførelsesform og udførelsesformeme vist i fig. 3-12 og fig. 17-20 er koblingsringen fleksibelt fastgjort til den fleksible plade 2,3,4 med de fordele, som er 30 forbundet med denne udformning som forklaret og beskrevet i medejede US patenter nr. 4.419.100 og 5.730.735 herved inkorporeret heri ved henvisning.In this embodiment and the embodiments shown in FIG. 3-12 and FIGS. 17-20, the coupling ring is flexibly attached to the flexible plate 2,3,4 with the advantages associated with this design as explained and described in co-owned US Patents Nos. 4,419,100 and 5,730,735 hereby incorporated by reference.
