Equashield's new SU-1 is a 1-mL closed system transfer device (CSTD) syringe that offers hazardous drug protection in pediatric oncology settings, where dosing is a fraction of what is required in adult chemotherapy treatments. The syringe allows for precision while maintaining the safety of the medical professionals administering the hazardous drugs. The SU-1 is a CSTD with closed pressure equalization and "dry" connectors integrated into a unique syringe. The encapsulated syringe barrel prevents plunger contamination and accidental disconnections. The pre-assembled syringe connects with a single motion to corresponding adaptors for vials, IV bags, and tubing.
