PROBLEM TO BE SOLVED: To provide a hemostatic device which can improve a hemostatic effect by restricting a reduction of blood flow amount in a radial artery while providing an appropriate pressing force to both arteria of the radial artery and an ulnar artery, thereby further improving the hemostatic effect.SOLUTION: A hemostatic device 10 includes: a flexible belt-like part 20 which can be wound around an arm inside which a radial artery 210 and an ulnar artery 230 travels through a fixing part 30 for fixing the belt-like part wound around the arm a first expansion part 50 connected to the belt-like part, the first expansion part 50 expanding by injecting a fluid therein to press a hemostatic part of the radial artery and a second expansion part 60 configured to be positioned at a position different from the first expansion part in a longitudinal direction of the belt-like part, the second expansion part being configured to press the ulnar artery. At least one of the belt-like part and the second expansion part includes a connection holding part 170 for movably holding the second expansion part in a longitudinal direction of the belt-like part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】橈骨動脈の血流量の減少を抑制して止血効果を高めるとともに、橈骨動脈および尺骨動脈の両動脈に対して適切な押圧力を付与することを可能にし、止血効果をより一層向上させる止血器具を提供する。【解決手段】止止血器具10は、橈骨動脈210および尺骨動脈230が走行する腕に巻き付けることが可能な可撓性を備える帯体20と、帯体を腕に巻き付けた状態で固定する固定部30と、帯体に連結されて流体を注入することにより拡張して、橈骨動脈の止血すべき部位を押圧可能な第1拡張部50と、帯体の長手方向において第1拡張部と異なる位置に配置可能に構成され、かつ、尺骨動脈を押圧可能な第2拡張部60と、を備え、帯体および第2拡張部の少なくとも一方は、帯体の長手方向に第2拡張部を移動可能に保持する連結保持部170を有する。【選択図】図1
