Heparin Lock

Heparin lock consists of a short catheter placed inside the vein and a locking valve. This valve allows healthcare providers to connect a syringe or infusion containing medication, and after the injection is complete, they can seal it without removing the catheter from the patient’s body. To prevent blood clotting inside the catheter, a heparin solution (an anticoagulant) is used to fill its interior, which is why this device is known as a “heparin lock.”

Some heparin locks feature additional elements, such as a “micro filter” to prevent microorganisms from entering the bloodstream. There are two main types of heparin locks:

Heparin lock with a screw-on cap: This type features a screw-on cap that provides a secure connection, preventing medication leakage and contaminants from entering the catheter.
Heparin lock with a locking system without heparin: Some newer heparin locks use designs that reduce the need for heparin injections, known as saline-locks.

Heparin locks offer many benefits, especially for patients who require frequent intravenous injections. By using a heparin lock, the frequency of vein punctures is reduced, minimizing patient discomfort and pain. Additionally, this device helps reduce the risk of infection and blood clot formation, providing stable and reliable venous access for healthcare providers.

Heparin lock is an efficient tool for long-term venous access that reduces the number of vein punctures, lowers pain and infection risks. Available in various types and sizes, it is used in different hospital departments, particularly for patients requiring long-term injections.
