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 an ulnar artery, thereby reducing a palsy or a pain caused by pressing the ulnar artery.SOLUTION: A hemostatic device 10 includes: a flexible belt-like part 20 which can be wound around an arm 200 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 an expansion part 50 connected to the belt-like part, the expansion part 50 expanding by injecting a fluid therein to press a hemostatic part 220 of the radial artery and a pressing member 60 configured to be positioned at a position different from the expansion part in a longitudinal direction of the belt-like part, the pressing member 60 being configured to press the ulnar artery. The pressing member is composed of a main body 61 and a salient part 62 provided to the main body and formed so as to project to the main body.SELECTED DRAWING: Figure 2COPYRIGHT: (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、尺骨動脈に対して適切な押圧力を付与することを可能にすることで、尺骨動脈の押圧によって生じるしびれや痛みを軽減することのできる止血器具を提供する。【解決手段】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200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220を押圧可能な拡張部50と、帯体の長手方向において拡張部と異なる位置に配置され、尺骨動脈を押圧可能な押圧部材60と、を備える。押圧部材は、本体部61と、本体部に配置され、前記本体部に対して突出した形状を有する凸部62と、から構成される。【選択図】図2
