The MaxPlus® opaque needlefree connector is a pioneer in positive displacement connector technology, and the number one needlefree valve in the United States, which provides a bolus of fluid to clear the catheter tip upon disconnection from the device. This helps reduce the risk of occlusions due to reflux. Patented Tru-Swab technology offers a flat, smooth surface free of nooks, crannies and slits that may harbor bacteria. Patented dual seal design helps reduce microbial ingress. One internal component helps reduce the risks associated with multiple moving parts that can hide contaminants and prevent complete flushing.
