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.

First claim

The invention claimed is:

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, and
at 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.

2. The hemostatic device of claim 1 , wherein the first linear side of the first balloon is adjacent the center of the compression member.

3. The hemostatic device of claim 2 , wherein the first linear side of the second balloon is adjacent the center of the compression member.

4. The hemostatic device of claim 3 , wherein the second balloon is at a position offset to the center of the compression member from the second end of the compression member.

5. The hemostatic device of claim 1 , wherein the first linear side of the second balloon is adjacent the center of the compression member.

6. The hemostatic device of claim 5 , wherein the second balloon is at a position offset to the center of the compression member from the second end of the compression member.

7. The hemostatic device of claim 1 , wherein the compression member is a curved frame comprising a plurality of rungs.

8. The hemostatic device of claim 1 , wherein the compression member is a curved plate.

9. The hemostatic device of claim 1 , wherein the width of the first balloon is about the same as the width of the band and the width of the second balloon is less than the width of the band.

10. The hemostatic device of claim 9 , wherein the width of the second balloon is less than 70% of the width of the band.

11. The hemostatic device of claim 1 , wherein a radius of curvature of the first curved portion of the compression member is about the same as a radius of curvature of the second curved portion of the compression member.

12. The hemostatic device of claim 1 , further comprising a first sleeve including a double layer construction defining a compression member holder, and the compression member is positioned in a gap in the double layer construction such that the compression member is held in the compression member holder.

13. The hemostatic device of claim 12 , further comprising a first tube communicating with an interior of the first balloon, a first adapter connected to the first tube and into which a first syringe is insertable to introduce a first fluid in the first syringe into the first balloon by way of the first tube, and a second tube communicating with an interior of the second balloon, a second adapter connected to the second tube and into which a second syringe is insertable to introduce a second fluid in the second syringe into the second balloon by way of the second tube.

14. The hemostatic device of claim 13 , further comprising a second sleeve including a double layer construction defining an adapter holder for the first adapter and the second adapter, and the first adapter and the second adapter are positioned in a gap in the double layer construction of the second sleeve such that the first and the second adapter are held in the adapter holder.

15. The hemostatic device of claim 13 , wherein the first adapter is identifiably different from the second adapter, wherein the identifiable difference comprises color, shape, texture or combination thereof.

16. The hemostatic device of claim 1 , further comprising a marker for positioning the first balloon at the site where bleeding is to be stopped.

17. The hemostatic device of claim 1 , wherein a surface of the first balloon that will contact skin at the puncture site is disposed with at least a vasodilator medication.

18. The hemostatic device of claim 1 , wherein the fastener comprises a hook material and a loop material, wherein the hook material is placed at a first end of the band and the loop material is placed at a second end of the band.

19. The hemostatic device of claim 1 , wherein the width of the band is greater than 40 mm.

20. The hemostatic device of claim 1 , wherein the width of the first balloon is about the same as the width of the band and the width of the second balloon is about the same as the width of the band.

21. 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, and at 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;
a second balloon provided on the inner peripheral side in the second half of the compression member at a position offset to the center of the compression member from the second end of the compression member, the second balloon comprising a plurality of linear sides;
wherein the first balloon is connected to the band only by a first connector on a first linear side of the first balloon, and the first linear side of the first balloon is adjacent the center of the compression member and perpendicular to the axis of the compression member; and
the second balloon is connected to the band only by a second connector on a first linear side of the second balloon, and the first lin
