Summary:Improved catheter system particularly adapted for multiple blood sample comprises a cannula defining a lumen having a side opening intermediate its ends, and an obturator slidably insertable in the lumen, the obturator being movable in the lumen between a first position wherein its proximal end extends proximally of the side opening and a second position wherein its proximal end terminates distally of the side opening. The side opening includes a tulip-shaped extension to permit the complete and efficient cleansing of the opening between multiple samplings of blood. Means for adapting the catheter system for continuous intravenous therapy are also disclosed.
