Kurin PIV sets are sterile, single-use blood culture collection sets that include the Kurin Lock®, a 4- or 6-inch flexible tubing extension set, an attached blood culture bottle holder, and a male luer intended for direct connection to a freshly placed peripheral IV (PIV) catheter to obtain blood culture samples. The Kurin Lock sidelines the initial flash of blood upon first access to the peripheral catheter. This device is to be used for blood collection ONLY. It is NOT to be used for infusion, IV administration or transfusion. The Kurin Lock for PIV should be used for ONLY freshly placed peripheral IVs, prior to any infusion.
