Abstract: A compression orb for use in combination with known bandage means to simulate manual digital pressure hemostasis following an arterial or venous puncture. The orb is formed from transparent plastic and is shaped as a hollow dome having a central, raised bulb or second, smaller dome which is integrally formed with and extends from the first domed portion. The flat, circular surface of the orb is releasably attached to the bandage means and the raised bulb portion of the orb is pressed upon the puncture site by means of the secured bandage. The bandage means includes a transparent window through which the orb and puncture site may be viewed without having to lift the bandage and orb from the wound to check for bleeding.
