The Safety Is In The Details

OnGuard® Closed System Transfer Device (CSTD) is designed with your safety in mind—whether you’re a healthcare professional or a patient. 

Simple, Safe, and Secure


Safety by Design

Unlike other closed system transfer devices (CSTDs), OnGuard locks with a simple click during handling, so there's no question you're protected. Only OnGuard CSTD was tested with hazardous drugs for vapor containment. Designed to provide simple, safe, easy-to-use protection for nurses, pharmacists, and your patients. 


Safety Made Simple

OnGuard CSTD was designed to provide simple, safe technology that helps you meet USP <800>, as well as protect against:

  • Harmful inhalation
  • Skin absorption
  • Ingestion
  • Accidental injection (needle stick)

Safety in Reduced Numbers

The OnGuard system has a minimal number of SKUs, for streamlined compounding. In fact, most hazardous drug compounding can be done with just three SKUs—promoting safety through SKU reduction, because sometimes, less is more.
