Abstract

SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA. This patent application proposes a self-adhesive dressing (1) equipped with a spacing structure to protect the wound area, said spacing structure being defined as a contoured and raised border (5), which incorporates an outer wall (6) that is supported internally by a profiled border (7); the profiled border (7) has a horizontal base face (8) that is coplanar with the surface (4) of the self-adhesive and elastic bandage (2), said horizontal base face (8) has a vertical orthogonal branch (9) that configures the support for the contoured border (10) of the outer wall (6) of the contoured and raised border (5), which defines and frames an area (11) that is closed by a mesh fabric sector (12) analogous to gauze; the surrounding and elevated surface (5) may have an outer wall (6) based on a solid profile (19); the purpose of the dressing (1) is to maintain a spacing area (20) between the mesh fabric sector (12) or mesh structure (25) and the wound to be protected.

Claims (8)

  1. 1. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, the dressing (1) is defined by a self-adhesive and elastic bandage (2), which has micro-perforations (3) along its surface (4); the adhesive surface (13) of the self-adhesive and elastic bandage (2) is protected by two plastic film sectors (14) and (15), each of which has a region of mutual overlap (16) in which the straight edge (14A) of the plastic film sector (14) overlaps the corresponding region of the straight edge (15A) of the plastic film sector (15), the dressing (1) being characterized by the self-adhesive and elastic bandage (2) having a contoured and raised edge (5), which incorporates an outer wall (6) that is supported internally by a profiled edge (7); The profiled edge (7) has a horizontal base face (8) that is coplanar with the surface (4) of the self-adhesive and elastic bandage (2), said horizontal base face (8) has a vertical orthogonal branch (9) that forms the support for the contouring edge (10) of the outer wall (6) of the contouring and raised edge (5), which defines and frames an area (11) that is closed by a section of mesh fabric (12) analogous to gauze; the contouring and raised surface (5) may have the outer wall (6) based on a solid profile (19).
  2. 2. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, the dressing (1) being characterized by having a defined spacing area (20).
  3. 3. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, characterized in that the dressing (1) has a variant in which it assumes a circular shape (21) with a circular bandage border (21A).
  4. 4. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, characterized in that the dressing (1) has a variant in which it assumes a square shape (22) with a square-shaped border (22A).
  5. 5. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, characterized in that the dressing (1) has a variant in which it assumes a rectangular shape (23) with a rectangular border (23A).
  6. 6. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, characterized in that the dressing (1) has a variant in which it assumes a circular shape (24) with projecting cross bandage tabs (24A).
  7. 7. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 1, characterized in that the dressing (1) alternatively incorporates and replaces the mesh fabric section (12) a mesh structure (25) that may be semi-rigid and may be made of plastic.
  8. 8. “SELF-ADHESIVE DRESSING WITH SPACING STRUCTURE TO PROTECT THE WOUND AREA”, according to claim 7, characterized in that the mesh structure (25) of the dressing (1) has a domed-convex shape (26).

Description

FIELD OF APPLICATION [001] This Patent Application refers to a self-adhesive bandage, of the type popularly known by the brand name “BAND-AID”, which generally falls within the field of products related to products and procedures intended for the application of wound dressings. PREAMBLE [002] This patent application is intended to provide a self-adhesive dressing, of the “BAND-AID” type, which innovates by incorporating a structure that promotes the spacing of part of its covering that rests on the wound, thus contributing positively to an improved condition for wound healing. This dressing is intended for, but not exclusively, use on wounds that present as blisters or similar. STATE OF THE ART [003] Currently, self-adhesive bandages known as "BAND-AIDs" are very popular and widely used. This type of bandage was developed in the 1920s by Johnson & Johnson employee Earle Dickson and basically consists of a self-adhesive and elastic bandage with micro-perforations along its surface, which allow the skin to breathe. In the center of the bandage there is a thicker lining that acts both as protection and also allows the skin to breathe, particularly at the site of the wound. The adhesive surface of the bandage is normally protected by two sections of plastic film that are removed and discarded when the bandage is actually used. [004] Although the term “BAND-AID” is a registered trademark owned by Johnson & Johnson, it has come to be used by the general public as a synonym for this type of bandage, even though there are other manufacturers that also produce their own versions which, however, do not deviate from the classic basic structure that has characterized the product since its inception. [005] The current state of the art can be defined by several patent applications, but in the present case it is concretized by the specific citation of two documents, one of which is the American patent US20120283614, granted on 02/05/2011 and entitled “BAND-AID”, while the other document, also as a way of demonstrating the wide diversity of this type of product that even goes beyond its use in humans, is the document MU79032206-0, filed on 13/04/1999 and entitled “APPLICATOR OF NUTRIENT PESTICIDES IN THE FORM OF A BAND-AID OR PLASTER FOR PLANTS IN GENERAL”. STATE OF THE ART PROBLEMS [006] Band-Aids have been widely used for over a hundred years and undoubtedly represent a practical way to protect minor wounds, thus providing ideal conditions for their healing. [007] It turns out that the layer of material that actually comes into contact with the wound area and that has characteristics that allow the skin to breathe also acts, in a way, to smother the wound. [008] It also happens that the classic configuration of “BAND-AID” bandages does not fully adequately protect wounds in the form of blisters or those in areas where there is, for example, friction with clothing. OBJECTIVES OF THE INVENTION [009] In view of the state of the art described above, one of the objectives of this Patent Application is to propose a “BAND-AID” type dressing, which innovates by dispensing with the thicker material layer as a means of protection and by adopting a contoured and raised border incorporated into the self-adhesive bandage, which frames a section of mesh material that allows total air circulation and maintains a space in relation to the wound area, being particularly suitable for use in the case of wounds that have a blister shape or similar. [010] Another objective of this Invention Patent application is to propose a “BAND-AID” type dressing that, by adopting a contoured and raised border that acts as a spacing structure in relation to the skin, allows the injured area to be kept away from contact with clothing and similar items, thus increasing the possibility of healing the wound itself. BRIEF DESCRIPTION OF THE INVENTION [011] Based on the context described above, the object of this Patent Application was developed, which describes a SELF-ADHESIVE DRESSING WITH A SPACING STRUCTURE TO PROTECT THE WOUND AREA. The dressing is defined by a self-adhesive and elastic bandage with micro-perforations along its surface, which allow the skin to breathe. At the center of the bandage is a contoured and raised border that acts as a spacing structure. The contoured and raised border defines an area that is closed by a section of mesh fabric. The adhesive surface of the bandage is protected by two sections of plastic film that are removed and discarded when the dressing is actually used. DESCRIPTION OF THE FIGURES [012] The self-adhesive dressing with spacing structure to protect the wound area, the subject of this Patent Application, will be described in detail with reference to the drawings below, in which: - Figure 1 illustrates a perspective view of the dressing proposed herein; - Figure 2 illustrates a top view of the dressing that is the subject of this Patent Application; - Figure 3 illustrates a side view of the dressing presented herein,
