a third band configured to be connected to the pressing member;

the pressing member including an inflatable member configured to compress the puncture site and a support member configured to fix the pressing member;

the support member including a first region in which the pressing member is located, and a second region which is located outside the first region and to which the first band, the second band, and the third band are connectable;

the third band extending in a different direction from the first band and the second band in a state where the third band is connected to the second region;

wherein the support member includes a projection protruding toward the pressing member on a third band side of the first region;

wherein the projection extends from the third band side of the first region to a center point side of the first region; and

wherein a thickness of the projection decreases from the third band side of the first region toward the center point side of the first region.

2 . The hemostatic device according to claim 1 , wherein

the projection has an inclined portion that extends from the third band side of the first region toward a central region located at a center of the first region and comes into contact with the pressing member;

the inflatable member is configured to be inflated by injecting a fluid, and

a thickness of the projection is larger than a thickness of the central region located at the center of the first region of the support member.

3 . The hemostatic device according to claim 1 , wherein

the projection has an external shape bilaterally symmetrical with respect to a major axis of the third band.

4 . The hemostatic device according to claim 1 , wherein

the inflatable member has a peripheral edge portion located at a peripheral edge of a portion that is configured to be inflated by injecting a fluid, and

a peripheral edge of the projection has a shape matching the peripheral edge portion of the inflatable member.

5 . The hemostatic device according to claim 1 , wherein

the inflatable member is configured to be inflated by injecting a fluid,

the projection has an inner surface located in a direction of facing the pressing member, and

the inner surface of the projection has at least one guide groove configured to hold a part of an elongated medical device.

6 . A hemostatic method comprising:

providing the hemostatic device of claim 1 ;

positioning the pressing member on the support member of the hemostatic device over the puncture site formed in the patient; and

attaching the pressing member on the support member of the hemostatic device to the patient with the first band, the second band, and the third band.

7 . A hemostatic device comprising:

a pressing member configured to compress a puncture site formed in a patient;

a first band configured to be connected to the pressing member;

a second band configured to be connected to the pressing member;

a third band configured to be connected to the pressing member;

the pressing member including an inflatable member configured to compress the puncture site and a support member configured to fix the pressing member;

the support member including a first region in which the pressing member is located, and a second region which is located outside the first region and to which the first band, the second band, and the third band are connectable;

the third band extending in a different direction from the first band and the second band in a state where the third band is connected to the second region;

wherein the support member includes a projection protruding toward the pressing member on a third band side of the first region;

wherein the first region of the support member includes a central region located at a center of the first region and a curved region curved in a direction away from the pressing member from the central region toward a peripheral edge of the support member; and

the projection is located in the curved region, and at least a part of the projection protrudesto a pressing member side relative to the central region.

8 . A hemostatic device comprising:

a pressing member configured to compress a puncture site formed in a patient;

a first band configured to be connected to the pressing member;

a second band configured to be connected to the pressing member;

a third band configured to be connected to the pressing member;

the pressing member including an inflatable member configured to compress the puncture site and a support member configured to fix the pressing member;

the support member including a first region in which the pressing member is located, and a second region which is located outside the first region and to which the first band, the second band, and the third band are connectable;

the third band extending in a different direction from the first band and the second band in a state where the third band is connected to the second region;

wherein the support member includes a projection protruding toward the pressing member on a third band side of the first region;

wherein the projection has an inner surface located in a direction of facing the pressing member; and

the inner surface of the projection has a shape in which a cross section in a direction intersecting with a direction in which the third band extends is curved in a concave shape away from the pressing member.
