Abstract
PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.
Claims5
An IV access device comprising:
- a catheter adapter having a proximal end and a distal end and a sidewall forming a lumen that extends therebetween;
- a catheter that extends from the distal end;
- a side port that extends outwardly from the sidewall of the catheter adapter, the side port being in fluid communication with the lumen of the catheter adapter;
- and
- a flow diverting feature configured to divert fluid flowing through the side port and into the lumen in a proximal direction, wherein the flow diverting feature comprises a diverter that is positioned centrally within an opening of the side port to thereby form a distal channel and a proximal channel around the diverter for fluid flowing from the side port and into the lumen, wherein a cross-section of the diverter comprises a first face aligned with a longitudinal axis of the catheter adapter, a second face proximate the first face and aligned with a longitudinal axis of the side port, and a third face extending between the first face and the second face and angled with respect to the first face and the second face.
