Inserting a Hep lock, also known as a heparin lock, involves gaining access to the bloodstream through a vein, typically in the arm. Here's a breakdown of the process:
- Vein Access: A needle is inserted into a vein, usually in the arm.
- Catheter Insertion: A catheter is then passed directly into the lumen (the inside space) of the vein.
- Needle Removal: The needle is removed, leaving the catheter in place.
- Locking the Catheter: The catheter is "locked" to prevent blood from flowing backward and potentially clotting inside the catheter.
Essentially, a Hep lock provides a port for administering medications or drawing blood without repeated needle sticks.
