A single lumen has one tube, or lumen, through which fluids or gases can be administered, removed, or measured. Single-lumen catheters can be made of various materials, such as silicone or polyurethane, and they are available in different sizes and lengths to meet the needs of different patients and medical procedures.
Single-lumen catheters can be used in a variety of medical procedures, including intravenous (IV) therapy, blood transfusions, and certain diagnostic tests. They are typically made from materials that are biocompatible and can be safely used within the body, such as silicone or polyurethane. Single-lumen catheters may be designed for either short-term or long-term use, depending on the specific medical needs of the patient.
