ABSTRACT:
A flashback structure of the type primarily designed to be used in combination with a catheter assembly and more specifically structured to provide clear visual indication of blood flow along a circuitous path of fluid flow which is indicative of proper placement of the sharpened tip of a needle in a blood vessel. Blood flow is retained within the path of fluid flow by a cover sleeve disposed in covering relation to the flow path.
