Prior studies have linked microbial contamination of intravenous (IV) ports and stopcocks with postoperative infections. Existing technologies to address contamination are not consistently utilized because of the time and effort they require. Herein, novel barrier devices were created that form a protective shell to passively prevent contact between injection sites and practitioner hands or environmental surfaces while still allowing rapid connection of a syringe for injection of medications via an opening in the shell. Prototypes were tested using a grossly contaminated environment and adenosine triphosphate (ATP)-bioluminescence assay. For eight pairs of unshielded versus shielded IV ports/stopcocks, average contamination was 4102 versus 35 RLU (p < 0.02), respectively, indicating that the devices could significantly reduce IV port/stopcock contamination.
