What's the fuction of a heparin cap?

A heparin cap is a sterile medical device used to seal the end of an intravenous (IV) catheter/cannula.

Core Functions:

1.Prevent Catheter ClottingIt contains a small amount of heparin (anticoagulant) to stop blood from clotting inside the IV line, keeping the catheter patent (open) for repeated use.

2.Seal and Protect the IV PortSeals the end of the IV catheter to block bacteria, dirt, and air entry, reducing risk of infection and air embolism.

3.Maintain Vascular AccessAllows the IV line to be locked and kept in place when not in use (no continuous infusion), enabling quick access for future medication, injection, or blood drawing without reinserting a new IV.

4.Needleless Safe ConnectionWorks with needleless connectors to avoid needlestick injuries for medical staff.
