1. A hemostatic device comprising:

  • a flexible band adapted to be wrapped around a wrist of a patient at a puncture site on the wrist where bleeding is to be stopped;

    a fastener for securing the band in a wrapped state to the patient'"'"'s wrist;

    a curved frame having an inner peripheral side, the curved frame is made of a material such that the curved frame is more rigid than the band, and at least a portion of which is curved toward the inner peripheral side;

    the curved frame possessing a first curved portion in a first half of the curved frame located between a center and a first end of the curved frame, a second curved portion in a second half of the curved frame located between the center and a second end of the curved frame, and an axis traversing from the first end of the curved frame, through the center, to the second end of the curved frame;

    a first balloon provided on the inner peripheral side in the first half of the curved frame at a position deviated to the center of the curved frame from the first end of the curved frame in a lengthwise direction of the band, the first balloon having a plurality of linear sides and is connected to the band by a first connector only on a first linear side of the first balloon, said first linear side of the first balloon being adjacent the center of the curved frame and perpendicular to the axis of the curved frame, the first balloon having a first surface and at least a second linear side in contact with the band, wherein the first balloon inflates when a fluid is introduced therein and upon inflation the first surface and at least the second linear side of the first balloon are capable of moving out of contact with the band; and

    a second balloon provided on the inner peripheral side in the second half of the curved frame at a position deviated to an edge of the curved frame from the center of the curved frame in a widthwise direction of the band, the second balloon having a plurality of linear sides and is connected to the band by a second connector only on a first linear side of the second balloon, the second balloon having a second surface and at least a second linear side in contact with the band, wherein the second balloon inflates when the fluid is introduced therein and upon inflation the second surface and at least the second linear side of the second balloon are capable of moving out of contact with the band.
