PROBLEM TO BE SOLVED: To provide a hemostatic device capable of excellently keeping the strength of an expansion part and temporally reducing compression force applied to a site where bleeding should be stopped so as to prevent vascular occlusion without needing an operation by a doctor or a nurse.SOLUTION: A hemostatic device 10 includes a belt body 20 wound around a puncture site P of the wrist W, fixing means 30 for fixing the belt body in the state of being wound around the wrist, and an expansion body 40 connected to the belt body that expands by the injection of fluid. The expansion body includes an expansion part 43 that can expand by the injection of fluid, and a joint part 50 formed at a portion of a peripheral edge part of the expansion part. The joint part includes a first joint part 51, a second joint part 52 whose joining strength is smaller than that of the first joint part, and a peeling start part 53 formed from the expansion part to the second joint part side so that the second joint part can be peeled temporally by keeping the expansion body in an expanded state.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】拡張部の強度を良好に保つことができ、かつ、医師や看護師が操作することなく、血管閉塞を防止できる程度に止血すべき部位に作用する圧迫力を経時的に低減可能な止血器具を提供する。【解決手段】止血器具10は、手首Wの穿刺部位Pに巻き付けるための帯体20と、帯体を手首に巻き付けた状態で固定する固定手段30と、帯体に連結され、かつ、流体を注入することにより拡張する拡張体40と、を備え、拡張体は、流体の注入によって拡張可能な拡張部43と、拡張部の周縁部の一部に形成された接合部50と、を有する。接合部は、第1接合部51と、第1接合部よりも接合力が小さい第2接合部52と、拡張体を拡張した状態に維持することで、第2接合部が経時的に剥離できるように拡張部から第2接合部側に向かって形成される剥離開始部53と、を有する。【選択図】図1
