BD PosiFlush 3ml Heparin Lock Flush Syringe ( 100 Usp Units/ ml)

This product is a pre-filled syringe designed for the maintenance of intravenous (IV) catheter patency. Each syringe contains 3 milliliters of a heparinized saline solution, standardized to 100 USP units of heparin per milliliter. The syringe is specifically engineered to deliver a controlled volume and concentration of heparin, which acts as an anticoagulant to prevent blood clots from forming within indwelling vascular access devices.

The design aims to minimize the risk of catheter occlusion, thereby ensuring the continued functionality of IV lines for medication administration and fluid delivery. The syringe is intended for single use to maintain sterility and prevent cross-contamination. The plunger mechanism is designed for smooth operation, allowing for precise dispensing of the flush solution.

The connection to the IV catheter is typically a Luer-lock fitting, ensuring a secure and leak-free attachment. The heparin concentration is a critical component, providing sufficient anticoagulant activity to keep the catheter lumen clear without causing systemic anticoagulation effects in most patients. The 3ml volume is a standard amount used for flushing most peripheral and central venous catheters.

The product is manufactured to meet established medical device standards for safety and efficacy.
