The HemaClear ™ OHK Medical Device HemaClear™, approved by FDA, consists of a silicon ring wrapped in a stockinet sleeve and pull straps (Fig.1). It performs three functions - blood removal (exsanguinations), arterial flow occlusion, and placement of sterile stockinet 30. The ring is placed on the extremity and then straps are pulled proximally. The silicone ring rolls up the limb while the stockinet sleeve unfolds onto the limb. During the rolling up process, the ring exerts pressure and squeezes the blood away from the limb. Application of the device takes less than a minute.
