Abstract

A hemostatic device is provided to stop bleeding at a puncture site on an artery 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 compression member 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 compression member and a second balloon provided on the inner peripheral side in the second half of the curved compression member. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and 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 flexible band configured to be wrapped around an individual's arm in which a radial artery and an ulnar artery are located, the flexible band possessing a longitudinal extent that extends in a longitudinal direction;
the flexible band including two parts that engage one another when the flexible band is wrapped around the individual's arm in a wrapped state to secure the flexible band to the individual's arm;
a compression member connected to the flexible band, the compression member being more rigid than the flexible band, the compression member including a first portion and a second portion that are spaced apart from one another in the longitudinal direction;
a first inflatable member connected to the flexible band and possessing an interior, the first portion of the compression member overlying the first inflatable member so that the first inflatable member is positioned between the first portion of the compression member and the individual's arm when the flexible band is wrapped around the individual's arm in the wrapped state;
a first lumen in communication with the interior of the first inflatable member to introduce fluid into the interior of the first inflatable member when the flexible band is wrapped around the individual's arm in the wrapped state to expand the first inflatable member and press a part of the radial artery to be subjected to hemostasis, the first inflatable member possessing an exterior surface;
a second inflatable member connected to the flexible band and possessing an interior, the second portion of the compression member overlying the second inflatable member so that the second inflatable member is positioned between the second portion of the compression member and the individual's arm when the flexible band is wrapped around the individual's arm in the wrapped state;
a second lumen in communication with the interior of the second inflatable member to introduce fluid into the interior of the second inflatable member when the flexible band is wrapped around the individual's arm in the wrapped state to expand the second inflatable member and press a part of the ulnar artery; and
an auxiliary balloon possessing an interior and expandable upon being inflated in response to introducing fluid into the interior of the auxiliary balloon, the auxiliary balloon being disposed between the second portion of the compression member and the second inflatable member so that the auxiliary balloon presses the second inflatable member on the ulnar artery when the auxiliary balloon is inflated.

2. The hemostatic device according to claim 1 , wherein at least a part of the auxiliary balloon overlaps with the second inflatable member.

3. The hemostatic device according to claim 1 , wherein the second inflatable member includes two ends, one of the ends being located closer to the first inflatable member in the longitudinal direction of the band than the other end, the auxiliary balloon including opposite end portions, one of the end portions of the auxiliary balloon being located closer to the first inflatable member in the longitudinal direction of the band than the other end portion of the auxiliary balloon, the one end portion of the auxiliary balloon overlapping the one end of the second inflatable member.

4. The hemostatic device according to claim 1 , further comprising a communication path communicating the interior of the auxiliary balloon with the interior of the second inflatable portion.

5. The hemostatic device according to claim 1 , wherein the second inflatable member includes two ends, one of the ends being located closer to the first inflatable member in the longitudinal direction of the band than the other end, the auxiliary balloon including opposite end portions, one of the end portions of the auxiliary balloon being located closer to the first inflatable member in the longitudinal direction of the band than the other end portion of the auxiliary balloon, the other end portion of the auxiliary balloon extending beyond the other end of the second inflatable member.

6. The hemostatic device according to claim 1 , wherein the compression member possesses an inner surface, the inner surface of the first and second portions of the compression member being curved.

7. The hemostatic device according to claim 1 , wherein the first inflatable member is connected to the flexible band by virtue of one end portion of the first inflatable member being fixed to the flexible band, and the second inflatable member is connected to the flexible band by virtue of one end portion of the second inflatable member being fixed to the flexible band.

8. The hemostatic device according to claim 1 , further comprising an auxiliary compressing member expandable upon being inflated in response to introducing fluid into an interior of the auxiliary compressing portion and disposed between the flexible band and the first inflatable member at a position in which at least a part of the auxiliary compressing member overlaps the first inflatable member to press the first inflatable member when the auxiliary balloon is inflated.

9. A hemostatic device comprising:
a flexible band configured to be wrapped around an arm in which a radial artery and an ulnar artery are located, the flexible band possessing a longitudinal extent that extends in a longitudinal direction;
a securing portion that secures the flexible band on the arm while the flexible band is wrapped around the arm in a wrapped state;
a first inflatable member connected to the flexible band and expandable upon being inflated in response to introducing fluid into an interior of the first inflatable member to press a part of the radial artery to be subjected to hemostasis, the first inflatable member possessing oppositely facing surfaces, the first inflatable member possessing an interior and an outwardly facing outer surface;
a second inflatable member disposed at a position spaced from the first inflatable member in a longitudinal direction of the band and expandable upon being inflated in response to introducing fluid into an interior of the second inflatable member, the first inflatable member possessing oppositely facing surfaces; and
an auxiliary balloon expandable upon being inflated in response to introducing fluid into an interior of the auxiliary balloon and disposed between the flexible band and the second inflatable member at a position in which at least a portion of the auxiliary balloon overlaps the second inflatable member to press the second inflatable member when the auxiliary balloon is inflated.

10. The hemostatic device according to claim 9 , wherein all or part of the auxiliary balloon overlaps the second inflatable member.

11. The hemostatic device according to claim 10 , wherein the second inflatable member includes one end portion located closer to the first inflatable member in the longitudinal direction of the band and an opposite end portion, the auxiliary balloon including one end portion located closer to the first inflatable member in the longitudinal direction of the band and an opposite end portion, the one end portion of the auxiliary balloon overlapping the one end portion of the second inflatable member.

12. The hemostatic device according to claim 9 , wherein the interior of the auxiliary balloon communicates with the interior of the second inflatable portion.

13. The hemostatic device according to claim 9 , wherein the auxiliary balloon is connected to the second inflatable member.

14. The hemostatic device according to claim 9 , further comprising a compression member that is more rigid than the
