Kind Code:
A1
Abstract:
Provided is a hemostasis device having such a configuration that an extension part in a shrunk state can be properly aligned with a puncture site even when the extension part is extended and shrunk repeatedly. The hemostasis device (10) is provided with: a cover member (100) that is configured so as to cover a first puncture site (p1); and a pressing member (200) that is connected to the cover member (100) and is configured so as to apply compression to the first puncture site (p1). The pressing member (200) has: an extension part (210) that is configured so as to be extended and shrunk by the injection of a fluid; and an injection part (270) that is configured so as to inject a fluid into the extension part (210). When the extension part (210) is in an extended state, the extension part (210) has: a bottom surface part (220); a column part (230) that rises from the bottom surface part (220); and a curved surface part (24) that forms an upper surface of the column part (230). The extension part (210) is configured such that the thickness (D1) of the curved surface part (240) becomes smaller than the thickness (D2) of the column part (230).
