Abstract

A primary packaging for a surface-stabilized surgical dressing (3) comprises a carrier layer (4), a contact surface with adhesive regions on the side nearer the skin which is protected, before the surgical dressing is used, by a detachable covering layer (6), and a supporting film (7) which comprises at least one layer detachably applied to the surface of the carrier layer (4) farther from the skin and which can be removed from the surgical dressing (3) after application. The supporting film (7) forms part of the protective packaging of the surgical dressing (3).

Bar* v__—- ; — “* I DK 175334 B1 I 1 I Opfindelsen angår en primaeremballage til fladestabiliserede I forbindsstoffer, hvilken primaeremballage omfatter et bære- I lag og en kontaktflade, der vender mod huden, og som har I klæbeområder, hvilken kontaktflade er beskyttet af et I 5 aftageligt dæklag, før forbindsstoffet tages i brug, og en I aftagelig understøttende folie med mindst ét lag, hvilken I folie er anbragt på bærelagets overside, der vender bort I fra huden, og kan fjernes fra det applicerede forbindsstof.Bar * v __—-; The invention relates to a primer package for surface stabilized dressings, which primer comprises a support layer and a contact surface facing the skin, which has adhesive areas, which contact surface is protected by an I 5 detachable cover layer prior to use of the dressing, and a removable support film of at least one layer, which film is placed on the upper surface of the support layer which faces away from the skin and can be removed from the applied dressing material.

I Den understøttende folie fjernes fra det applicerede for- I 10 bindsstof efter at have opfyldt sin fladestabiliserende I funktion i forhold til bærelaget.The supporting film is removed from the applied binder after fulfilling its surface stabilizing function relative to the support layer.

I Forbindsstofferne kan inddeles i to hovedgrupper. Den ene I gruppe omfatter de forbindsstoffer, der bliver fikseret på I applikationsstedet ved hjælp af yderligere indretninger I 15 eller foranstaltninger, medens fikseringen i den anden I gruppe sker ved hjælp af klæbeområder på selve forbinds- I stoffet. For den sidste gruppes vedkommende har kravet om I tynde og fleksible bærelag, som sikrer en acceptabel vand- I dampsgennemtrængelighed og en god tilslutning til applika- I 20 tionsstedets konturer, givet vanskeligheder ved applika- I tionen. Efter at dæklaget er blevet fjernet, sker der I således for eksempel let indrulning af kantområder, indbyr- I des sammenklæbning af klæbeområder og sammenfoldning, I hvilket gør det pågældende forbindsstof uanvendeligt.In the dressing materials can be divided into two main groups. One in the group comprises the adhesives which are fixed at the application site by means of additional devices I or measures, while the fixation in the other I group is done by means of adhesive areas on the fabric itself. For the latter group, the requirement for thin and flexible carriers, which ensure an acceptable water vapor permeability and a good connection to the application site contours, has given application difficulties. Thus, for example, after the cover has been removed, you easily roll in edge areas, interlocking adhesive areas and folding, rendering the adhesive in question unusable.

I 25 En forbedring har her kunnet opnås ved anvendelse af en I såkaldt understøttende folie til fladestabilisering (jfr.I 25 An improvement has been achieved here by the use of a so-called support stabilizer for surface stabilization (cf.

I Det må ganske vist anses for at være ufordelagtigt, at den I understøttende folie bliver kastet bort efter at være I fjernet fra det applicerede forbindsstof, og den fladesta- I biliserende funktion deraf dermed begrænses.

In addition to impervious paper, polymers or metal-containing materials, such as are generally used, which in structural terms H can be attributed to textile, flat parts. The material selected for the supporting foil and the other packaging need not be the same, but must be adapted to the given requirements.

Emballagen kan på kendt måde være udstyret med mindst én åbningshjælpeanordning, fx rivetråde, perforeringer eller 15 lignende.

In a particularly preferred embodiment, the dressing contains at least one active substance. It may be in a transdermal therapeutic system where a piecemeal wrap is unavoidable.

I Opfindelsen forklares nærmere nedenfor ved hjælp af den H 20 medfølgende tegning.The invention is explained in more detail below by means of the accompanying drawing.

I Som vist i fig. 1 er et bærelag 4 bestående af et tekstil- I materiale belagt med et klæbende lag 5, som kan indeholde I en farmakologisk virksom substans, og som har et dæklag 6 I 30 på den side, der vender mod huden, hvilket dæklag her I består af et papir, der er gjort ikke-klæbende ved siliko- I nisering. Den understøttende folie 7 rager ud over bærela- 5 DK 175334 B1 get 4 på alle sider og består af et i forhold til bærelaget stift flerlagsfoliemateriale. Folien er ved varmeforsegling forbundet med bærelaget 4 på stederne 8, der er fordelt efter et forudbestemt mønster, idet der under varmeforseg-5 lingen dannes en forseglingskant 11 med den underliggende emballagefolie 10.I As shown in FIG. 1 is a support layer 4 consisting of a textile I material coated with an adhesive layer 5 which may contain a pharmacologically active substance and having a coating layer 6 I 30 on the side facing the skin, which coating layer here consists of of a paper made non-sticky by siliconization. The supporting foil 7 extends beyond the support layer 4 on all sides and consists of a rigid multilayer foil material in relation to the support layer. The foil is, by heat sealing, connected to the support layer 4 at the locations 8 distributed according to a predetermined pattern, forming a sealing edge 11 with the underlying packaging foil 10 during the heat sealing 5.

I figur 2 er vist en yderligere foretrukken udførelsesform ifølge opfindelsen, hvor den understøttende folie 7 har samme størrelse som bærelaget. Emballagefolien 10 omslutter 10 forbindsstoffet og er sammenklæbet med den understøttende folie 7 langs kanterne af oversiden deraf. Klæbelaget 5 har her intet særligt dæklag, idet emballagefolien 10 overtager funktionen som beskyttelseslag. Umiddelbart efter emballagens åbning kan forbindsstoffet appliceres.Figure 2 shows a further preferred embodiment of the invention, wherein the supporting film 7 is the same size as the support layer. The packaging foil 10 encloses the connector fabric and is adhered to the supporting foil 7 along the edges of the upper side thereof. The adhesive layer 5 has no special covering layer here, since the packaging foil 10 assumes the function of protective layer. Immediately after opening the package, the dressing material can be applied.

In one or two consecutive steps, the rim seal and the release of the detachable are then performed between the supporting foil and the support layer.
