Apparatus and method to stop bleeding
First Claim
1. A frame comprising:
- (i) a plurality of rungs;
(ii) at least two beams holding said plurality of rungs;
said frame being a compression member in a hemostasis device comprising at least one radial balloon attached to a band, a portion of the band defining a frame holder, the frame holder holding the frame, the at least one radial balloon configured to compress a radial artery at a puncture site on a wrist to attain hemostasis, the at least one radial balloon positioned underneath a first half of the frame holder, wherein during operation, when the at least one radial balloon expands and compresses the puncture site to stop bleeding, the frame performs by keeping at least a portion of the band defining a second half of the frame holder pressing on at least a portion of a base of a palm of the wrist, thereby facilitating compression of an ulnar artery.

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.

11. A frame comprising:
-
(i) a plurality of rungs; (ii) at least two beams holding said plurality of rungs; (iii) curved solid pieces at proximal and distal ends of the frame, with the plurality of rungs being in a center portion of the frame; and said frame being configured for placement in a frame holder of a hemostasis device, the hemostasis device comprising at least one radial balloon to compress a radial artery at a puncture site on a wrist to attain hemostasis, the at least one radial balloon positioned underneath a first half of the frame holder, wherein during operation, when the at least one radial balloon expands and compresses the puncture site to stop bleeding, the frame performs by flexing whereby at least a portion of the band defining a second half of the frame holder remains pressing on at least a portion of a base of a palm of the wrist. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A curved frame compression member configured for placement in a curved frame holder of a flexible band, a portion of the flexible band defining the curved frame holder, the flexible band adapted to be wrapped around a wrist of a patient at a puncture site where bleeding is to be stopped using at least a radial balloon to compress on the puncture site, comprising:
-
(i) a plurality of rungs; (ii) two beams holding said plurality of rungs; (iii) curved solid pieces at proximal and distal ends of the curved frame, with the plurality of rungs being in a center portion of the curved frame; and
the radial balloon positioned underneath a first half of the curved frame holder, wherein during operation, when the radial balloon expands and compresses the puncture site to stop bleeding, the curved frame performs by flexing whereby at least a portion of the flexible band defining a second half of the curved frame holder remains in contact with at least a portion of the wrist, thereby facilitating compression of an ulnar artery. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
