IV Set Extension, Extension Tube IV & IV Extension Set - Sterile Medical Tubing Kits

Light-proof extension tubes are specialized infusion accessories designed to shield light-sensitive medications from harmful light exposure during delivery, ensuring the stability and efficacy of the drugs. These tubes are constructed with a multi-layered material, where an inner layer of medical-grade PVC is combined with an outer light-blocking layer, typically made of opaque polypropylene or a pigmented polymer, to prevent ultraviolet (UV) and visible light penetration.

A key feature is their ability to block over 99% of light in the 200-700nm wavelength range, which is critical for medications such as certain antibiotics, chemotherapy drugs, and vitamins that degrade when exposed to light. This protection starts from the moment the medication enters the tube, maintaining the drug’s chemical integrity throughout the infusion process, reducing the risk of ineffective treatment or adverse reactions caused by light-induced degradation.

Like standard extension tubes, they come with secure luer lock connectors at both ends, ensuring a tight fit with infusion sets, pumps, or IV catheters. The tubing maintains flexibility despite the light-blocking layer, allowing for easy handling and positioning without compromising the light-proof effect. Some models also include clear windows at specific points, enabling medical staff to monitor fluid flow and check for air bubbles without exposing the entire length of the tube to light.

Available in lengths from 80cm to 180cm, light-proof extension tubes are widely used in oncology, neonatal care, and critical care units where light-sensitive drugs are frequently administered. They are disposable and pre-sterilized, adhering to strict safety standards to prevent contamination. By preserving the potency of light-sensitive medications, these extension tubes play a vital role in ensuring the success of infusion therapies that rely on such drugs.
