PROBLEM TO BE SOLVED: To provide a wound covering material capable of retaining a wounded part in a moist state.SOLUTION: The wound covering material includes: a front surface sheet 2 located on a wounded part side of a wearer, allowing a transuding fluid from the wounded part to permeate a rear surface sheet 3 located on the outer surface side opposite from the wounded part side of the wearer and an absorber 4 disposed between the front surface sheet 2 and the rear surface sheet 3, capable of absorbing the transuding fluid permeating the front surface sheet 2. The front surface sheet 2 has a porous sheet 5 to abut to the wounded part and the skin surface of the wearer. An plurality of openings 7 through which the transuding fluid can pass are disposed at positions corresponding to the absorber 4 on the porous sheet 5. The diameter of each opening 7 on the porous sheet 5 is at least 0.3 mm and not more than 1.0 mm. The unopened part length L from an end of one opening 7 to an end of the closest other opening 7 on the porous sheet 5 is at least 3.3 mm and not more than 11.0 mm.COPYRIGHT: (C)2011,JPO&INPIT【課題】創傷部を湿潤な状態に維持できる創傷被覆材を提供する。【解決手段】装着者の創傷部側に位置し、この創傷部からの浸出液が通過可能な表面シート2と、装着者の創傷部側とは反対の外面側に位置する裏面シート3と、これら表面シート2および裏面シート3の間に配設され、表面シート2を通過した浸出液を吸収可能な吸収体4とを備える。表面シート2は、装着者の創傷部および肌面に当接する有孔シート5を有する。この有孔シート5における吸収体4に対応する位置に浸出液が通過可能な複数の開孔部7を設ける。有孔シート5の各開孔部7の直径を0.3mm以上1.0mm以下にする。また、有孔シート5の一の開孔部7の縁部から最も近くに位置する他の開孔部7の縁部までの非開孔部間距離Lを3.3mm以上11.0mm以下にする。【選択図】図1
