CATHETER SYSTEM TO FACILITATE BLOOD COLLECTION AND RELATED METHODS

Abstract:

A catheter system may include a catheter adapter, which may include a distal end, a proximal end, a lumen extending through the distal end and the proximal end, and a side port in fluid communication with the lumen. A catheter may extend distally from the catheter adapter. A septum may be disposed within the lumen. The septum may include a first slit generally aligned with a longitudinal axis of the catheter and a second slit offset from the longitudinal axis of the catheter. An introducer needle may be secured within a needle hub and may extend through the catheter and the first slit of the septum. A winged needle set may include: a body; a needle extending distally from the body and through the second slit of the septum; an extension tube extending from the body; and a blood collection device coupled to the extension tube.
