Abstract
Catheter assemblies may include introducer needles having a notch or similar structure that allows flashback blood to enter the annular space between a catheter tube and an introducer needle of an IV catheter. The presence of flashback blood in this annular space can provide a clinician with an early, visible indication that a needle has entered a vein. The notch, however, may create a leak path for blood to escape outside of the catheter assembly, unless contained. Disclosed herein is a notch containment that prevents the notch from providing a leak path for blood to escape outside of the catheter during or after needle withdrawal.
