Apparatus and method to stop bleeding
First Claim
1. A hemostatic device comprising:
- a 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 compression member having an inner peripheral side, the compression member made of a material such that the compression member is more rigid than the band, andat least a portion of the compression member is curved toward the inner peripheral side;
the compression member possessing a first curved portion in a first half of the compression member located between a center and a first end of the compression member, a second curved portion in a second half of the compression member located between the center and a second end of the compression member, and an axis traversing from the first end of the compression member, through the center, to the second end of the compression member;
a first balloon provided on the inner peripheral side in the first half of the compression member at a position offset to the center of the compression member from the first end of the compression member, the first balloon comprising a plurality of linear sides, wherein the first balloon is connected to the band by a first connector only on a first linear side of the first balloon; and
a second balloon provided on the inner peripheral side in the second half of the compression member, the second balloon comprising a plurality of linear sides, wherein the second balloon is connected to the band by a second connector only on a first linear side of the second balloon;
wherein the first linear side of the first balloon is perpendicular to the axis of the compression member and the first linear side of the second balloon is perpendicular to the axis of the compression member.

Abstract
A hemostatic device is provided to stop bleeding at a puncture site on the wrist of a patient, the device comprising a transparent flexible band to be wrapped at the site where the bleeding is to be stopped, a curved frame having an inner peripheral side and possessing a first curved portion in its first half and a second curved portion in its second half, a first balloon provided on the inner peripheral side in the first half of the curved frame and a second balloon provided on the inner peripheral side in the second half of the curved frame. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and the blood flow in the first artery is increased by compression of a second artery using inflation of the second balloon.
