On iv lock意思

"IV lock" is a term used in healthcare and specifically in the context of intravenous (IV) therapy. It stands for "intravenous lock" or "IV catheter lock." This term refers to a procedure where a small catheter (a thin, flexible tube) is inserted into a vein, typically in the arm, to provide direct access to the bloodstream for the administration of fluids, medications, or nutrients.

The IV lock procedure involves flushing the catheter with a solution, such as heparin (a blood thinner), after the completion of an IV infusion to keep the catheter open and prevent blood clots from forming inside it. This allows the catheter to be used again for future IV treatments without the need for a new insertion, which can be painful and increase the risk of infection.

An IV lock is often used when patients require intermittent IV therapy over a period of time, such as in the case of chemotherapy treatments, long-term antibiotic therapy, or when fluids and medications need to be administered periodically. It is a common practice in hospitals, clinics, and sometimes at home for patients who require ongoing IV treatments.
