EQUASHIELD® - AN INNOVATIVE CLOSED SYSTEM TRANSFER DEVICE

The EQUASHIELD Closed System Transfer Device was developed as a result of years of in-depth research through including assessment of potential routes of exposure, safety factors, and analysis of leading Closed System Transfer Devices on the market. The result is a completely airtight, leakproof and user friendly Closed System Transfer Device that complies with the strictest aseptic technique requirements and guidelines set forth by NIOSH and OSHA. EQUASHIELD’s CSTD Syringe Unit has two chambers, the proximal liquid chamber, and the distal air chamber that is located at the end of the piston. A dual needle system for the air to liquid exchange communicates with each chamber respectively. As the piston moves, one chamber’s volume increases, while the other chamber’s volume decreases by precisely the same amount. Consequently, any displacement of liquid from the vial is supplanted by an equivalent amount of air that is added to or subtracted from the vial, respectively. A typical chemotherapy session requires the transfer of a cytotoxic drugs from a vial to a syringe, and then to the infusion bag. The typical pressure disparity during drug transfer expels vapors, droplets and aerosols into the work environment, one of the main routes of exposure. Maintaining constant pressure equalization inside the vial, the EQUASHIELD Closed System Transfer Device prevents the escape of vapors and aerosols providing full protection against these harms.

EQUASHIELD’s CSTD design also relies on the proven concept of tight seal double membranes to keep connectors and residual free despite multiple entries.
