Vascular catheter/cannula flush solution, anticoagulant, non-antimicrobial

Vascular catheter/cannula flush solutions with anticoagulants are sterile liquids designed to keep intravenous access devices open and functional. Clinically, they prevent clotting in the lumen of peripheral IV cannulas or central venous catheters by introducing a low-dose anticoagulant, ensuring uninterrupted fluid administration or medication delivery.

These solutions are typically single-use, supplied in small containers or prefilled syringes, and regulated as medical devices rather than drugs. They are classified based on their intended use and risk profile, with variations in concentration and formulation depending on the manufacturer’s design and jurisdiction-specific requirements.
