1. A hemostatic device comprising:

  • a flexible band configured to be wrapped around a wrist of a patient at a site where bleeding is to be stopped so that the flexible band is in a wrapped state on the patient'"'"'s wrist;

    a fastener to secure the flexible band in the wrapped state around the patient'"'"'s wrist;

    a curved plate possessing an inner surface and an outer surface, the curved plate defining a concave curve along the inner surface;

    a balloon positionable between the curved plate and the patient'"'"'s wrist in the wrapped state of the flexible band, the balloon including a center, the balloon being inflatable upon introducing gas into the balloon when the flexible band is in the wrapped state with the balloon positioned between the patient'"'"'s wrist and the plate to apply a compressive force to the site where bleeding is to be stopped;

    a marker located to position the center of the balloon at the site where bleeding is to be stopped;

    the band, the balloon and the curved plate being fabricated from substantially transparent materials permitting visualization of the site where bleeding is to be stopped when the flexible band is in the wrapped state with the balloon positioned between the patient'"'"'s wrist and the curved plate; and

    the balloon being made of a gas permeable material selected so that after the balloon is inflated by the gas, the gas in the balloon is gradually released through the gas permeable material to outside the balloon to gradually decrease the compressive force applied to the site where bleeding is to be stopped.
