A device for the protection of skin lesions of various kinds, in particular lesions following biopsy interventions, comprising: a first sheet having a central opening; a spacing element on the first sheet, made of a non-rigid material soaked with substances having bacteriostatic, bactericidal, germicidal or fungicidal activity, and having a central opening of smaller size than the central opening in the first sheet, and the center of which is essentially coincident with the center of the opening in the first sheet, so that part of the spacing element comes into contact with the skin in an area surrounding the lesion; and a second sheet, made with a material having micro-porosity preferably lower than 0.5 μm, placed over the spacing element so as to close the top of the central opening in said spacing element and to form, when the device is in contact with the skin, a closed chamber. |

1. A device for protection of skin lesions, comprising:
a first sheet of a flexible and gas-permeable material having an opening in its central part, said first sheet having an outside face and a skinside face opposite said outside face, a discontinuous deposit of an adhesive material present on said skinside face, said first sheet opening having a first perimeter; a spacing element placed over the outside face of the first sheet, of thickness between 0.2 and 2 cm and having lateral size equal to or lower than that of said first sheet, being soaked, or being covered with a material soaked, with a substance having biocidal activity, said spacing element having an opening in its central part, said spacing element opening having a second perimeter of smaller size than said first perimeter, said spacing element placed onto and resting on the first sheet outside face in such a position that a center of said spacing element opening is coincident with a center of said first sheet opening, that said second perimeter is completely encircled in said first perimeter, and that a portion of the spacing element outside said second perimeter extends into the first sheet opening; and a second sheet, permeable to gases but impermeable to liquid water and made of, or comprising, a metalized material opaque to UV rays, placed over said spacing element and fixed either to the spacing element, or to the first sheet along a third perimeter surrounding a contact area between said spacing element and said first sheet, wherein said second sheet and said spacing element opening form a hollow chamber with one open face, with an arrangement such that an outer edge of the spacing element is protected from contact with an external atmosphere. |
