Definitions
- the present invention refers to a skin-friendly bandage or dressing for covering wounds, burns or similar damages of the human skin, or ostomi openings.
- a skin-friendly dressing comprising a water soluble or water swellable hydrocolloid, a water-insoluble, viscous elastomeric binder and optionally also a tackifying resin.
- This known dressing is formed as a sealing pad having bevelled outer edges and optionally also, if annular, a bevelled inner edge.
- An object of the present invention is to provide a bandage or wound dressing having a high moisture absorbing capa ⁇ city and simultaneously a high degree of flexibility for covering surface areas of the human body.
- the skin-friendly bandage or dressing comprises a moisture absorbing, to skin and mucous membranes adhering adhesive sheet, consisting of a layer of a water swellable colloid which is dispersed in or mixed with a water insoluble viscous elastomer binder and, if desired, usual auxiliary materials, the adhesive sheet at one outwardly directed surface being firmly connected to a non-adhesive water impervious cover layer, and the other against the skin or mucous membrane directed ad ⁇ hesive surface being provided with a removable protecting sheet.
- the bandage or wound dressing is specificly characterized in that the adhesive sheet is provided with one or several grooves or ditches that fully or partly surround the central part of the adhesive sheet.
- the swellable colloid particles preferably consist of one or more water soluble or water swellable hydrocolloid polymers or gums. Suitable examples are carboxy ethylcellulose, dextran, pectin, guar gum and polyvinylalkohol. Further examples of such materials are mentioned in US 4 867 748, EP 0 122 344.
- the elastomer binder acting as a medium for dispersing the hydrocolloid particles, is any known water-insoluble elastomeric substance, preferably a polymer or copolymer. Suitable examples are polyisobutylene, silicone rubber, acrylonitride rubber, polyurethane etc. Further examples may be derived from the above mentioned EP 0 122 344.
- any common used auxiliary material may be included as a component of the dressing, such as antioxidants, for example butylated hydroxyamisole or hydroxytoluene, deodorants such as chlorophyllins, or perfume agents. It is also common practice to add pharmacologically active ingredients in the adhesive composition, such as antibiotic or antimicrobial agents, such as neomycin, an antiseptic agents such as povidone iodine, and/or an antiinflammatory agent such as hydrocortisone or triamcinolone acetomide.
- antibiotic or antimicrobial agents such as neomycin
- an antiseptic agents such as povidone iodine
- an antiinflammatory agent such as hydrocortisone or triamcinolone acetomide.
- the impervious cover layer may consist of any known useful material for the purpose. Examples of such materials are any film forming polymer, such as polyethylene, polypro ⁇ pylene, polyester, pol vinylchloride, polyvinyliden- chloride, polyvinylacetate, polyamide, polyvinylether and polyurethane.
- the impervious cover layer may also be a foam, such as polyurethane foam or polyether foam.
- the bandage or wound dressing may, according to an embodiment of the invention, have a hole in the central part.
- the groove's or ditches may preferably have such a depth that the thickness of the sheet at the bottom of the ditch is less than 1/4 of the thickness of the sheet between the ditches.
- the width of the grooves or ditches is up to three times the depth and, preferably, the width has the same size as the depth. A maximum of flexibility is thus obtained.
- the grooves or ditches impart highly increased flexibility to the dressing.
- Fig. 1, 4 and 5 are three different embodiments of the bandage according to the invention, seen from above,
- Fig. 2, 3 and 6 illustrate various forms of grooves or ditches in the bandage
- Fig. 7 illustrates a special embodiment in which only a distal part of the bandage has grooves.
- the bandage illustrated in fig. 1 consists of a circular sheet with an outer edge 1 and two grooves 2, 3.
- the central part 4 has a uniform maximum thickness.
- the grooves may have different profiles such as V- or U-shapes.
- An impervious cover layer 6 consisting of a polymer film or a thin foam layer is placed on top of the outer surface.
- the surface to be placed against the skin is provided with adhesive layer 8 covered by a protective removable film 7.
- One or two concentric grooves improves considerably the resistance to radial swelling. This property may be measured by a method described below.
- the central part 4 may be a hole as illustrated in fig. 4.
- This embodiment is suitable as bandage for ostomi open ⁇ ings. Increased flexibility is obtained due to cencentric ditches 3 as well as radial ditches 2. Such a bandage can be rather thick having a high absorption capacity and still being highly flexible.
- the bandage shown in fig. 5 has an elliptical outer edge 1.
- the bandage shown in fig. 7 is intended to be placed at a vertical surface of a body area, the distal part directed downward in order to minimize swelling in the downward direction.
- the dressings according to the invention may be manufactured in various ways, e.g. by a die-casting process or a pressing process. An adequate method of manufacturing the dressing is disclosed by US 4 867 748.
- An apparatus of a sheet of glass (25 x 25 cm) with a cen ⁇ tral hole of 20 mm is connected to a reservoir of water via a tube mounted on to the said hole.
- the product to be tested is applied with the hole as centrum.
- Physiological saline is introduced to the product adhering to the glass sheet by elevating the reservoir for said saline to a position above the product.
- a pressure of 2-10 cm of water column is applied to the product and the radially swelling from the hole out through the product may be determined.
- the test is perfomed at 37 °C and readings are taken at the times; 6 hours, 24 hours, 2, 3 and 4 days.
- the glass plate is placed horizontally in the test.
- a test product from the category of hydrocolloid dressings and with a content of 40% particles of sodiumcarboxy- methyl-cellulose dispersed in an elastomeric binder con- sisting of polyisobutylene and covered by a polyurethane film of 30 u was tested as a plane sheet and formed with 2 grooves as shown in fig. 1.
- the grooves are concentric and centrally placed with deformation diameters of 24 mm and 34 mm.
- the radial swellings at 12 hours are identical for the two dressings. However, when passing the first deformation after 24 hours a decrease in radial swelling velocity of 13% is observed for the deformed version and this decrease has after further 3 days further increased to a level of 30%.
