PROBLEM TO BE SOLVED: To provide a wound covering material that can form a wet environment necessary for the growth of epidermal cells as well as can suppress pH rise in the wound surface due to elution of alkaline components and in addition can elute wound healing components and antibacterial components.SOLUTION: The wound covering material is characterized in that a glass material containing, as a glass composition, B2O3 and CaO is contained in a matrix layer composed of a water-soluble or hydrophilic polymer having an acidic functional group.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】表皮細胞の増殖に必要な湿潤環境を形成するとともに、アルカリ成分の溶出による創面のpH上昇を抑制し、しかも創傷治癒成分及び抗菌性成分を溶出可能な創傷被覆材を提供する。【解決手段】酸性官能基を有する水溶性又は親水性の高分子で構成されるマトリックス層中に、ガラス組成としてB2O3とCaOを含有するガラス材が含まれていることを特徴とする。【選択図】図1
