Freshly Placed Peripheral Catheter Collections

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.


Inspect and open the packaging.
Visually inspect the device and packaging to confirm there is no damage (device is not cracked, broken). If the packaging appears to be damaged (punctured, torn) do not use the device.

Peel the label to remove the device.


Secure connections.
Ensure that the blood culture bottle holder is secure before use.

Although best practice supports maintaining a closed system in blood culture collection, if it is necessary to collect the blood specimen with a syringe, the blood culture bottle holder may be removed.


Perform skin antisepsis.
Disinfect and prep the site for IV insertion.


Attach syringe or blood culture bottle holder.
A blood culture bottle holder comes pre-attached to the Kurin PIV set to aid in maintaining a closed system for collection. If it is necessary to collect the blood specimen with a syringe, the blood culture bottle holder may be removed.


Insert peripheral IV catheter and connect the Kurin extension set.
Place the peripheral IV in accordance with hospital protocol and connect the luer lock of the Kurin Set to the PIV catheter.


Watch for the blood flow to stop.
Once the Kurin set is connected, observe the flow of blood into the U-shaped side channel. Watch for the blood flow to stop at a variable distance in the sampling channel.

The set is now ready for blood sample collection.


Collect the ordered specimens.
Attach blood collection vials to blood culture bottle holder to collect blood samples or draw blood using a syringe and fill each bottle according to policy.

If collecting additional labs, ensure blood cultures are collected first and then collect additional specimens ordered.

If the device includes an extension set:

  • Complete the collection, engage the clamp and disconnect the Kurin device.
  • Attach needleless connector to extension set and flush according to hospital policy.

Dispose of the set.
Dispose of the set in accordance with hospital protocol.
