HEMOSTATIC INSTRUMENT

[Problem] To prevent an external force from being unintentionally applied to a puncture site and/or to prevent a hemostatic device from shifting due to unintentional application of the external force to an inflatable member, when an operator attaches a tube portion to and detaches the tube portion from a tube fixing portion in a state in which the hemostatic device is attached to a hand of a patient.[Means for Resolution] A hemostatic device (100) includes a tube fixing portion (300) that is provided to a fixing member which fixes an inflatable member (110).The tube fixing portion includes a first member (310), a second member (320) that is located closer to the inflatable member than is the first member, a slit portion (330), and a tube holding portion (340).A part of the first member is further away from the inflatable member than is the second member in a direction perpendicular to a virtual plane (S) defined by the slit portion. A first distal-end surface (313) includes a first region (313a) not facing a second distal-end surface (323), and a second region (313b) facing the second distal-end surface. A first curved portion (312) has a first curved surface (312a) curved toward the second member and facing the second distal-end surface (323) .
