EQUASHIELD®’s Vial Adaptor firmly snaps onto a standard vial with a unique mechanism that prevents angled or non-centered spiking. The vial adaptor provides a safe and contamination-free vial access port for the Syringe Unit. As part of EQUASHIELD®’s connector system, the vial adaptor’s elastomeric membrane serves a dual purpose; to serve as a microbial barrier preventing microbial ingress, while remaining drug residue-free for up to 10 repeated connections in 7 days.

Preventing the Escape of Vapor

Unlike bulky balloon systems, EQUASHIELD® has streamlined the design by creating a unique closed internal equalization system which makes it sleek and easy to use.

To offset the pressure differential during withdrawal, the short needle draws medication out of the vial while the air needle replaces the liquid with an equal amount of air to maintain equilibrium. The sterile air is automatically drawn from the syringe’s sealed air chamber and injected into the vial. During reconstitution of lyophilized powder, the process is reversed; the short needle injects liquid into the vial, while the long air needle offsets overpressure by drawing toxic vapors into the air chamber at the back of the syringe. 

EQUASHIELD® ensures constant equilibrium.
