PROBLEM TO BE SOLVED: To provide a hemostatic device capable of temporally and automatically reducing pressing force applied to a site whose bleeding is to be stopped, without using a dedicated instrument as a separate body from the hemostatic device.SOLUTION: A hemostatic device 10 includes: a belt body 20 to be wound around a puncture site of a wrist a hook-and-loop fastener 30 for fixing the belt body with it wound around the wrist a pressing part 40 connected to the belt body and pressing the puncture site and a control mechanism 50 that controls movement of the pressing part with respect to the puncture site so as to control the pressing force of the pressing part to the puncture site. The control mechanism includes a spring mechanism 60 for transmitting force to the pressing part and having a spiral spring member, and an operation part 70 applying the force to the spring member in response to the rotating operation.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】止血器具とは別体の専用の器具を使用することなく、止血すべき部位に付与する押圧力を経時的かつ自動的に減少させることが可能な止血器具を提供する。【解決手段】止血器具10は、手首の穿刺部位に巻きつけるための帯体20と、帯体を手首に巻きつけた状態で固定する面ファスナー30と、帯体に連結され、かつ、穿刺部位を押圧する押圧部40と、押圧部の穿刺部位に対する押圧力を制御できるように、押圧部の穿刺部位に対する移動を制御する制御機構50と、を備え、制御機構は、押圧部に力を伝達し、かつ、渦巻き状のバネ部材を有するゼンマイ機構60と、回転操作に伴いバネ部材に力を付与する操作部70と、を有している。【選択図】図2
