Apparatus and method to stop bleeding
First Claim
1. A curved frame configured for placement in a double layer construction defining a curved frame holder of a flexible band, said flexible band adapted to be wrapped around a wrist of a patient at a puncture site on a radial artery where bleeding is to be stopped using a first balloon to compress on the puncture site and a second balloon to compress on an ipsilateral ulnar artery, a first part of the curved frame overlapping the first balloon and a second part of the curved frame overlapping the second balloon, wherein the curved frame does not maintain a substantially fixed shape while a device comprising the flexible band and the curved frame is in operation applying ulnar and/or radial compression to a wrist during a hemostasis procedure, and wherein during operation the curved frame flexes with the balloons as the balloons expand and contract with pressure.

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.

- 1. A curved frame configured for placement in a double layer construction defining a curved frame holder of a flexible band, said flexible band adapted to be wrapped around a wrist of a patient at a puncture site on a radial artery where bleeding is to be stopped using a first balloon to compress on the puncture site and a second balloon to compress on an ipsilateral ulnar artery, a first part of the curved frame overlapping the first balloon and a second part of the curved frame overlapping the second balloon, wherein the curved frame does not maintain a substantially fixed shape while a device comprising the flexible band and the curved frame is in operation applying ulnar and/or radial compression to a wrist during a hemostasis procedure, and wherein during operation the curved frame flexes with the balloons as the balloons expand and contract with pressure.

11. A curved frame configured for placement in a double layer construction defining a curved frame holder of a flexible band, said flexible band adapted to be wrapped around a wrist of a patient at a puncture site on a radial artery where bleeding is to be stopped using at least a first balloon to compress on the puncture site and at least a second balloon to compress on an ipsilateral ulnar artery, a first part of the curved frame overlapping the at least first balloon and a second part of the curved frame overlapping the at least second balloon, comprising:
-
the curved frame being made of a material more rigid than the flexible band; the curved frame not maintaining a substantially fixed shape while a device comprising the flexible band and the curved frame is in operation applying ulnar and/or radial compression to a wrist during a hemostasis procedure; and the curved frame flexing with the at least first balloon and/or the at least second balloon during operation as the at least first balloon and the at least second balloon expand and contract with pressure, whereby in operation when the at least first balloon expands and compresses the puncture site on the radial artery to stop bleeding, the curved frame performs by keeping the flexible band pressing the wrist thereby facilitating compression of the ulnar artery while the at least second balloon expands. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A curved frame configured for placement in a double layer construction defining a curved frame holder of a flexible band, said flexible band adapted to be wrapped around a wrist of a patient at a puncture site on a radial artery where bleeding is to be stopped using at least a first balloon to compress on the puncture site, the at least first balloon positioned underneath a first half of the curved frame holder, comprising:
-
the curved frame being made of a material more rigid than the flexible band; the curved frame flexing with the at least first balloon as the at least first balloon expands and contracts with pressure; and wherein in operation when the at least first balloon expands and compresses the puncture site to stop bleeding, the curved frame performs by keeping at least a portion of the flexible band defining a second half of the curved frame holder pressing on at least a portion of a base of a palm of the wrist, thereby facilitating compression of an ulnar artery. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
