1. A hemostatic device comprising:
a main body belt configured to be wound around at least a part of a hand and a wrist of a patient, the main body belt having an inner surface that faces a surface of the patient when the main body belt is wound around at least the part of the hand and the wrist of the patient, the main body belt also having an outer surface that is opposite the inner surface;
a pressing member configured to be disposed at a site of the hand where bleeding is to be stopped to compress the site where bleeding is to be stopped;
the main body belt including a distal region and a proximal region that are positioned relative to one another so that when the pressing member is at the site on the hand where bleeding is to be stopped the proximal region of the main body belt is disposed at a position farther away from a fingertip of the hand of the patient than the distal region of the main body belt;
the distal region of the main body belt including an anchor portion that includes
overlying material that overlies a part of the inner surface of the main body belt before the main body belt is wound around at least the part of the hand and the wrist of the patient, the overlying material and the part of the inner surface of the main body belt defining a space portion configured to receive the finger of the patient so that the finger is positioned in the space portion before the main body belt is wound around at least the part of the hand and the wrist of the patient, the overlying material extending between a most proximal end of the overlying material and a most distal end of the overlying material,
an insertion port that is opened toward the proximal region and that communicates with the space portion to allow the finger of the patient to be inserted into the space portion, the insertion port being located at the most proximal end of the overlying material, and
a distal opening that communicates with the space portion to allow the fingertip of the finger of the patient inserted into the space portion to protrude distally beyond the anchor portion, the distal opening being located at the most distal end of the overlying material;
the pressing member being configured to allow the site where bleeding is to be stopped to be viewed from outside in a state in which the pressing member is disposed at the site where bleeding is to be stopped; and
the pressing member being fixed to the distal region of the main body belt at a position spaced on a proximal side from the insertion port and being fixed on the inner surface of the main body belt.
