Adapter to Facilitate Blood Draw and Infusion, Related Systems, And Methods

Abstract:

An adapter configured to couple to a catheter assembly. The adapter may include a first proximal port, a second proximal port, and a distal port. An infusion fluid pathway may extend between the first proximal port and the distal port. A blood withdrawal fluid pathway may extend between the second proximal port and the distal port. The adapter may include a one-way septum disposed in the first proximal port and configured to open to allow fluid flow in a distal direction at a pressure differential across the one-way septum. The one-way septum is disposed within the infusion fluid pathway. The adapter may include a two-way septum disposed in the second proximal port. The two-way septum may be disposed within the blood withdrawal fluid pathway.
