Abstract

A dressing suitable for topical application to the body, including a carrier substrate having a first side and opposing second side; and a layer of a foamed adhesive composition applied to the second side of the carrier substrate, where the layer of foamed adhesive composition includes a substantially homogeneous distribution of closed cells having an inert gas contained therein.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A dressing suitable for topical application to the body, comprising:
 a carrier substrate having a first side and opposing second side; and   a layer of a foamed adhesive composition applied to the second side of the carrier substrate, wherein the layer of foamed adhesive composition comprises a substantially homogeneous distribution of closed cells comprising an inert gas contained therein.   
     
     
         2 . The dressing of  claim 1  wherein the closed cells are ovoid, spherical, circular or elongate in structure. 
     
     
         3 . The dressing of  claim 1  wherein the closed cell comprises a cell dimension selected from the group consisting of average diameter, length and width. 
     
     
         4 . The dressing of  claim 3  wherein the cell dimension is from about 1 to about 10 micron. 
     
     
         5 . The dressing of  claim 3  wherein the cell dimension is from about 2 to about 5 micron. 
     
     
         6 . The dressing of  claim 1  wherein the layer of the foamed adhesive composition has a thickness from about 20 to about 200 micron. 
     
     
         7 . The dressing of  claim 1  wherein the layer of the foamed adhesive composition has a thickness from about 30 to about 100 micron. 
     
     
         8 . The dressing of  claim 1  wherein a ratio of the thickness of the layer of the foamed adhesive composition to the cell dimension is from about 0.005 to about 0.50. 
     
     
         9 . The dressing of  claim 1 , wherein a ratio of the thickness of the layer of the foamed adhesive composition to the average cell diameter is from about 0.03 to about 0.1. 
     
     
         10 . The dressing of  claim 1 , wherein the foamed adhesive composition has a density from about 0.14 to about 0.80 g/cm 3 . 
     
     
         11 . The dressing of  claim 1 , wherein the foamed adhesive composition has a density from about 0.19 to about 0.55 g/cm 3 . 
     
     
         12 . The dressing of  claim 1  wherein the Inert gas is selected from the group consisting of nitrogen, carbon dioxide, noble gases, hydrocarbons and air. 
     
     
         13 . The dressing of  claim 1  wherein the layer of foamed adhesive composition comprises from about 15% to about 70% by volume of the inert gas. 
     
     
         14 . The dressing of  claim 1  wherein the layer of foamed adhesive composition comprises from about 20% to about 60% by volume of the inert gas. 
     
     
         15 . The dressing of  claim 1  wherein the layer of foamed adhesive composition comprises from about 20% to about 40% by volume of the inert gas. 
     
     
         16 . The dressing of  claim 1  having a static shear of about 100 minutes or more. 
     
     
         17 . The dressing of  claim 1  having a static shear of about 300 minutes or more. 
     
     
         18 . The adhesive dressing of  claim 1  having a static shear of about 1500 minutes or more. 
     
     
         19 . The dressing of  claim 1  having a static shear of about 20% to about 80% of the static shear of an adhesive dressing comprising the carrier substrate and a layer of non-foamed adhesive composition, wherein the non-foamed adhesive composition is substantially similar to the foamed adhesive composition. 
     
     
         20 . The dressing of  claim 1  having a static shear of about 60% to about 80% of the static shear of an adhesive dressing comprising the carrier substrate and a layer of non-foamed adhesive composition, wherein the non-foamed adhesive composition is substantially similar to the foamed adhesive composition. 
     
     
         21 . The dressing of  claim 1  wherein the adhesive layer has a basis weight of from about 20 to about 150 g/m2. 
     
     
         22 . The dressing of  claim 1  wherein the adhesive layer has a basis weight of from about 30 to about 100 g/m2. 
     
     
         23 . The dressing of  claim 1  wherein the adhesive layer has a basis weight of from about 30 to about 60 g/m2. 
     
     
         24 . The dressing of  claim 1  wherein the closed cells comprise about 90% or more of the total number of cells in the adhesive layer. 
     
     
         25 . The dressing of  claim 1  wherein the closed cells comprise about 95% or more of the total number of cells in the adhesive layer.
