1. A hemostatic device that closes a puncture hole extending to skin from an opening formed in a blood vessel, the hemostatic device comprising:
a first tubular member extending in an extending direction;
a positioning member, a part of which is provided inside the first tubular member, the positioning member including
an extending section extending in the extending direction, and
an engagement section provided at a distal end section of the extending section and engageable with the opening;
a hemostatic agent disposed further to a proximal end side than the engagement section of the positioning member;
a push-out member including a push-out distal end positioned further to the proximal end side than the hemostatic agent, and able to push out the hemostatic agent from a distal end section of the first tubular member, using the push-out distal end, when the push-out member moves relatively to a distal end side with respect to the first tubular member;
a housing configured to house at least a part of each of the first tubular member, the positioning member, and the push-out member;
a first operation unit configured to be operated by a user in order to perform each of
a first distal end operation that relatively moves the first tubular member and the push-out member to the distal end side with respect to the housing and the positioning member, and
a second distal end operation that relatively moves the push-out member to the distal end side with respect to the housing and the positioning member;
a switching mechanism configured to restrict the second distal end operation at least until the first distal end operation is complete, and to release the restriction of the second distal end operation and cause the second distal end operation to be executable once the first distal end operation is complete;
a coupling section coupled to a second tubular member through an interior of which at least a part of each of the first tubular member, the positioning member, and the push-out member is inserted; and
a second operation unit that is operated in order to perform a coupling proximal end operation that moves the coupling section to the proximal end side with respect to the housing, the first tubular member, the positioning member, and the push-out member,
wherein the switching mechanism further restricts the coupling proximal end operation until the second distal end operation is complete, and releases the restriction of the coupling proximal end operation and causes the coupling proximal end operation to be executable once the second distal end operation is complete.
