PROBLEM TO BE SOLVED: To provide a wound dressing being less prone to cause discomfort, inflammation, traumatic tattoo, and hyperplastic scar on a skin after treatment, further substantially eliminating a patients pain when being used on a wound surface, preventing the wound surface from getting excessively wet, and capable of sustainedly releasing various types of ions with sterilization and cell proliferation effects to the wound surface.SOLUTION: The wound dressing is formed by superposing a first layer composed of a porous film, and a second layer composed of a glass material. The porous film includes micropores with a core diameter of less than 800 μm, formed on the film, and the glass material is composed of glass including B2O3 or CaO as glass compositions, where the first layer is located at a wound site side.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】治癒後の皮膚に違和感や炎症、外傷性刺青、肥厚性瘢痕を引き起こしにくく、さらに創面に使用時に患者の痛みが殆どなく、創面が過湿潤になるのを防ぐとともに、殺菌あるいは細胞増殖効果のある種々のイオンを創面に徐放可能な創傷被覆材を提供する。【解決手段】多孔フィルムからなる第1層とガラス材からなる第2層とが積層された創傷被覆材であって、前記多孔フィルムは、フィルムに形成される微細孔の孔径が800μm未満であり、前記ガラス材はガラス組成としてB2O3あるいはCaOを含有するガラスからなると共に、前記第1層が創傷部位側となることを特徴とする。【選択図】図1
