    摘要: As a wound dressing that includes a perforated material having through-holes, in which the perforated material can be coated with a low-adhesive resin without closing the through-holes, and that has excellent adhesion prevention properties to wounds, provided is a wound dressing 1 that includes a sheet-shaped perforated material 11 having through-holes 111 and a low-adhesive resin 12 with which at least one face of the perforated material 11 is coated without closing the through-holes 111, the perforated material 11 is a knitted fabric or a woven fabric formed of a multifilament, and the perforated material 11 has an average opening area of the through-holes 111 of 0.02 to 1.2 mm 2 and an average number of through-holes of 40 to 220 cm -2 . By designing the opening area of the through-hole 111 and the number of through-holes 111 in the perforated material 11 within the particular numerical ranges, such a wound dressing can be prevented from adhering to granulation tissues that invade the through-holes 111 and can ensure sufficient permeation properties of exudate through the through-holes 111.

    摘要: The invention relates to a breathing adhesive sheet material comprising a sheet layer having apertures and an adhesive coating layer with apertures corresponding to at least part of the apertures of said sheet layer, provided on one side of said sheet layer having apertures, wherein said apertures in said adhesive coating layer constitute portions of a substantially continuous adhesive coating layer separated there from by remaining adhered to a protective sheet layer upon removal thereof.
    The invention also relates to a composite sheet material comprising such adhesive sheet material with a removable protective sheet layer provided to separate portions from the continuous adhesive layer upon separation thereof from the adhesive sheet material.
    The invention also relates to a method for manufacturing such an adhesive sheet material comprising the steps of applying a layer of uncured adhesive material to a sheet layer having apertures and a layer of protective sheet material, and submitting the sheet layer having apertures, the layer of protective sheet material and the layer of uncured adhesive material to a curing operation, thereby causing the layer of adhesive material to preferentially adhere to the sheet layer having apertures outside the apertures, and to adhere to the protective sheet layer at said apertures.
