The ONGUARD Contained Medication System with TEVADAPTOR components from B. Braun is a closed system drug-transfer device that helps protect clinicians from exposure to hazardous drugs-whether liquid, gaseous, or particulate-during admixture, transport, administration, and disposal. A closed system for drug reconstitution and administration, ONGUARD meets the National Institute for Occupational Safety and Health (NIOSH) definition of a closed system drug transfer device. ONGUARD supports compliance recommendations made by NIOSH, USP<797>, and ASHP for handling hazardous medications. ONGUARD is easy to use and helps protect clinicians using passive needle safety while providing tactile and audible feedback to confirm secure connections.
