1. A hemostatic device attachable to a hand of a patient, comprising:
a covering member configured to cover a site where bleeding is to be stopped on a hand of a patient;
a securing member configured to secure the covering member to the hand when the covering member covers the site;
an inflatable member connected to the covering member and inflatable by injection of a fluid; and
a deformable auxiliary member having a smaller outer shape than an outer shape of the inflatable member, wherein
the covering member includes a main body, a first arm portion protruding from a first side of the main body, and a second arm portion protruding from a second side of the main body, wherein the first and second sides are opposite sides of the main body,
the main body includes a first end portion located on a distal side of the main body between the first arm portion and the second arm portion, and a second end portion located on a proximal side of the main body between the first arm portion and the second arm portion,
the inflatable member is connected to the second end portion of the main body, and
the auxiliary member is connected to the first end portion of the main body and is interposed between the main body and the inflatable member, the auxiliary member being located closer to a distal end of the main body than a proximal end thereof.
 
11. A hemostatic device attachable to a hand of a patient, comprising:
a main body below which first and second inflatable members are attached, wherein
the first inflatable member is connected to a proximal end of the main body and to be in contact with the hand,
the second inflatable member is connected to a distal end of the main body and sandwiched between the main body and the first inflatable member, and
the second inflatable member is located closer to the distal end of the main body than the proximal end thereof;
a first arm member extending from a first side of the main body that extends between the proximal and distal ends thereof; and
a second arm member extending from a second side of the main body that extends between the proximal and distal ends thereof,
wherein the first and second arm members are configured to be wrapped around the hand of the patient and exposed ends of the first and second arm members are attached to each other to secure the main body to the hand of the patient.
 
18. A method of securing a hemostatic device to a hand of a patient, the hemostatic device including: a covering member to be worn on the hand of the patient, a securing member that secures the covering member to the hand of the patient, an inflatable member connected to the covering member, and a deformable auxiliary member having a smaller outer shape than an outer shape of the inflatable member, wherein
the covering member includes a main body, a first arm portion protruding from a first side of the main body, and a second arm portion protruding from a second side of the main body, the main body including a first end portion located on a distal side of the main body between the first arm portion and the second arm portion, and a second end portion located on a proximal side of the main body between the first arm portion and the second arm portion,
the inflatable member is connected to the second end portion of the main body, and
the auxiliary member is connected to the first end portion of the main body while being interposed between the main body and the inflatable member, the auxiliary member being located closer to a distal end of the main body than a proximal end thereof, the method comprising:
placing the hemostatic device on the hand of the patient so that the main body is located at a site where bleeding is to be stopped on the hand of the patient;
securing the hemostatic device to the hand by connecting the first arm portion to the second arm portion; and
connecting a syringe to a tube connected to the inflatable member and injecting a fluid into the inflatable member using the syringe to inflate the inflatable member and the auxiliary member.
