Abstract
Intravenous (IV) catheters are critical for delivering medications directly into the bloodstream, but they pose a significant risk of catheter-related bloodstream infections (CRBSIs), which can lead to severe complications, prolonged hospital stays, and increased healthcare costs. With the IV catheter market projected to grow from USD 8.6 billion in 2022 to USD 17.8 billion by 2032, there is an urgent need for safer, more effective catheter systems. Lumenous Technologies offers a novel solution: an IV catheter connector equipped with a UV-C sterilization module designed to disinfect fluids before they enter the bloodstream. The device targets pathogens like E. coli and S. aureus using UV-C LEDs (270–280 nm) coiled around a central quartz glass tube housed within a reflective, 3D-printed PLA casing. The system is fully compatible with standard IV setups using male and female Luer lock adapters and is engineered for easy integration, low power usage, and high sterilization efficiency. The prototype underwent two verification tests: one assessing leak resistance and Luer lock compatibility, and another measuring sterilization effectiveness. Results showed zero leakage and a 100% fluid transfer rate through the device. Sterilization tests using E. coli-contaminated saline demonstrated an average bacterial reduction of 99.5%, meeting the benchmark for partial success. These results confirm the prototype has potential to meet its design goals and demonstrates promising potential as a continuous sterilization solution to reduce CRBSIs in clinical settings.
