How EQUASHIELD Closed System Transfer Device (CSTD) Works

Superior Safety
and Ease of Use Use your mouse’s scroll wheel or the arrow keys on your keyboard to advance the animation. Unparalleled Safety
and Ease of Use with
EQUASHIELD’s CSTD EQUASHIELD’s unique CSTD Syringe Unit features an integrated barrier type pressure equalization system, a leak-preventing dry disconnection mechanism, and an encapsulated closed back syringe with a metal plunger rod to mitigate hazardous drug contamination, preventing vapor escape and plunger contamination. EQUASHIELD is FDA cleared under ONB product code and CE marked.
 Covers More Routes of
Exposure The EQUASHIELD® Syringe Unit is uniquely designed with a closed-back structure and a fixed connector, preventing plunger detachment. With this feature EQUASHIELD® Syringe Unit eliminates more routes of hazardous drug exposure than alternative systems, providing enhanced safety while also enabling them to use the most accurate syringe size for compounding and administration procedures. Encapsulated Plunger No Plunger Contamination Undetachable Plunger Faster Compounding
While Preventing Spills The EQUASHIELD Syringe Unit features a factory-welded connector, streamlining setup and saving time [2] in comparison to the process of opening two packages and assembling a connector onto a regular off-the-shelf syringe. Furthermore, the welded EQUASHIELD Syringe Unit eliminates the risk of luer disconnection and potential spills.
Nothing In – Nothing Out EQUASHIELD’s system is FDA-cleared for preventing microbial ingress for up to 7 days [6]. In tests, Vial Adaptor membranes were exposed to bacteria over 10 times in 770 syringe units across 7 days [7]. Its telescoping spike ensures accurate vial entry, avoiding angular errors and bulky fixtures. Separate drug and gas channels are divided by a hydrophobic barrier to prevent liquid passage.
 The Vial Adaptor’s elastic membrane port has been validated for up to 10 connections with the Syringe Unit, ensuring no leaks or drug residuals on its surfaces [3], and effectively preventing transfer of environmental contaminants into the vial [4,5].
 Nothing in Nothing Out Uncontaminated 7 Days Centered Spiking Single Motion Connectors A simple, straight motion effortlessly connects and disconnects any EQUASIHELD components. The expansive flow channels in all system components facilitate swift transfers with minimal effort. Dry Connectors Needle Safe Safety Locks 10 Dry Connections &
Needle Safe The EQUASHIELD® connectors, through 10 repeated activations, have been proven to exhibit no leaks or drug residuals on external surfaces [3] They also efficiently prevent the introduction of environmental contaminants [7,8].

The FDA has acknowledged the effectiveness of the EQUASHIELD® system, labeling it as capable of Preventing Microbial Ingress for up to 7 days [9]. When the Syringe Unit connects to the Adaptor, internal needles pierce both membranes within a secure housing, reducing needlestick risk. On disconnection, the self-sealing membranes ensure a dry, drug-free surface. Closed Pressure Equalization Prevents the Escape of Vapors EQUASHIELD® Syringe Units maintain a closed pressure equalization that prevents the escape of vapors and aerosols during compounding and administration. A unique dual-needle, air-to-liquid exchange system, combined with a closed-back sterile air chamber behind the syringe, ensures that pressure is equalized in a system throughout the hazardous drug handling process.
 Pressure Equalization Internal Equalization Dry Disconnection With this feature EQUASHIELD® Syringe Unit eliminates more routes of hazardous drug exposure than alternative systems, providing enhanced safety while also enabling them to use the most accurate syringe size for compounding and administration procedures. The system’s closed Syringe Unit prevents intended and unintended syringe plunger detachment and can be used safely up to its maximal nominal volume with hazardous drugs [1]. The EQUASHIELD® Syringe Unit is uniquely designed with a closed-back structure and a fixed connector, preventing plunger detachment. Adaptors for All Central to these offerings is the shared closed mechanism for connection and disconnection, ensuring a seamless and uniform process. EQUASHIELD® offers an extensive array of Adaptors, Connectors, and Tubing sets to cater to various drug transfer scenarios, accommodating diverse vial sizes, IV Bags, and IV pushes.
