[0051] The belt is made of a substantially transparent polyvinyl chloride sheet material having a thickness of 0.5 mm. The length of the belt is 240mm and the width is 55mm. The radial artery balloon and the ulnar artery balloon were each made of a substantially transparent polyvinyl chloride sheet material having a thickness of 0.25 mm. The dimensions of the radial artery balloon are 38mm x 55mm and the dimensions of the ulnar artery balloon are 38mm x 38mm. The radial artery balloon, ulnar artery balloon, and bands are welded together where necessary to form a Figure 5 constructed hemostatic device. Two adapters with non-return valve via eg Figure 5 The catheter shown is connected to two balloons. The adapter is configured to lock with a luer lock syringe. The curved frame was made from 2mm diameter rungs with spaces between the 2mm rungs (center to center distance between rungs was 4mm). The crosspiece is held between two parallel beams of 3mm diameter. The frame i...

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 first balloon being larger than the second balloon. The bleeding from radial artery is stopped by compressing the radial artery at the puncture site using inflation of the first balloon and radial artery flow is increased by compression of ipsilateral ulnar artery using inflation of the second balloon.
