摘要:
A venous access device includes a hub and a bifurcated cannula. The hub includes a bifurcated connecting arm, a blood sampling arm connected to the bifurcated connecting arm, a fluid transfer arm connected to the bifurcated connecting arm, a blood sampling channel and a fluid transfer channel. The blood sampling channel passes through the blood sampling arm and the bifurcated connecting arm. The fluid transfer channel passes through the fluid transfer arm and the bifurcated connecting arm. The bifurcated cannula is coupled to the bifurcated connecting arm and includes a blood sampling lumen having a blood sampling port, a fluid transfer lumen having a fluid transfer port, and a dividing member separating the blood sampling lumen from the fluid transfer lumen. The blood sampling port is 2 mm to 20 mm proximal from the fluid transfer port. The blood sampling channel is fluidly connected to the blood sampling lumen, and the fluid transfer channel is fluidly connected to the fluid transfer lumen.
