Cannula and method for bidirectional blood flow |
摘要 |
A cannula and method for bidirectional blood flow, the cannula being constructed so as to provide a bifurcated flow path, each branch of the flow path independently communicating through telescoping cannulae and a venipuncture needle initially projecting beyond the exterior cannula to facilitate venipuncture and thereafter being displaceable away from the venipuncture site to permit unobstructed simultaneous fluid flow in opposite directions through each of the bifurcated flow paths.
