Infusion needle vents are self-sealing components integrated into the sheaths of infusion needles. These vents allow air or gases to pass freely through the porous medium; however, upon contact with liquid, they activate a self-sealing mechanism that blocks fluid passage, thereby preventing unintended liquid flow. Infusion sets equipped with such needle vents enhance operational ease and safety, significantly improve nursing efficiency, reduce medication waste, and help prevent environmental contamination from drug residue.
