Abstract: An arterial catheter system may include a catheter assembly, which may include a catheter adapter. The arterial catheter system may include an arterial catheter extending from a distal end of the catheter adapter. The arterial catheter system may include a needle assembly, which may include a needle hub and an introducer needle. The arterial catheter system may include an arterial hemoshield device coupled to the catheter assembly. The arterial catheter system may include a fluid pathway within the arterial catheter, the catheter adapter, and the arterial hemoshield device. A first fluidic resistance within a portion of the fluid pathway within the arterial hemoshield device may be greater than a second fluidic resistance within the fluid pathway distal to the portion of the fluid pathway.

Abstract: An arterial catheter system may include a catheter assembly, which may include a catheter hub and an arterial catheter. The arterial catheter system may include a needle assembly, which may include a needle hub and an introducer needle. The arterial catheter system may include an extension tube coupled to the catheter assembly and a fluid pathway extending through the arterial catheter, catheter hub, and the extension tube. A first fluidic resistance within a portion of the fluid pathway within the extension tube may be greater than a second fluidic resistance within the fluid pathway distal to or proximal to the portion of the fluid pathway. The extension tube may have a length L and an inner diameter D. A geometric factor Gf of the portion of the fluid pathway may equal L/D4 and may be selected to reduce hemolysis during blood draw from an artery.
