Overview

The Antimicrobial MicroClave needlefree connector contains silver that is impregnated into both the split septum silicone seal and internal blunt cannula, which provides an even and continuous distribution of silver ions. Silver escapes into all areas surrounding the silicone including the internal fluid path and area between the silicone and housing.

The design of your needlefree intravenous (IV) connectors plays a substantial role in your ability limit hospital-acquired bloodstream infections (HA-BSI).² During the production process, ionic silver is integrated into both the split-septum and internal fluid path for a continuous 96-hour use life. Not only does the Antimicrobial MicroClave provide enhanced patient safety through innovative technology, but it has also been proven to provide an effective microbial barrier against bacteria transfer and contamination.^3,4

Additional Features:

The Antimicrobial MicroClave can be used on all peripheral, arterial, and central venous catheters for the administration of IV fluids or medications, and can be used with blood products and power injectors.
Does not require a change in clinical practice or technique and may help you address recent concerns raised by the FDA regarding the safety of positive displacement connectors.⁵

How it works

Unique features of the Antimicrobial MicroClave that may help reduce the risk of bacterial contamination:

Ionic silver additive is integrated into both the split-septum and internal fluid path for a continuous 96-hour use life.
Split-septum is noted in the CDC draft guidelines as a preferred design feature for connectors.⁶
Straight fluid path allows for clearing of blood and blood residual with low flush volumes.⁷
Minimal deadspace (also referred to as residual volume) of 0.04 mL allows for lower flush volumes.
Flat smooth swabable surface for ease of disinfection.
Approved for use with power injectors.

Accessing the Fluid Path

When Antimicrobial MicroClave is not being accessed, the silicone seal forms a safe, swabbable barrier to bacterial ingress.
Upon luer access, the silicone seal is depressed and the fluid path windows are exposed through the device's split septum.
Fluid is either infused or aspirated through the connector and catheter via the dedicated straight internal fluid path.

Product Reference

Disinfect to Protect

When placing a new Antimicrobial MicroClave on a catheter, disinfect the catheter hub and prime the Antimicrobial MicroClave.
Before accessing a Antimicrobial MicroClave, always disinfect the injection site with the approved antiseptic per facility protocol.
Scrub the injection site in accordance with facility protocol for appropriate scrubbing and dry times.

Disinfect to Protect

Administer or Aspirate

Attach IV tubing, syringe or blood tube holder to Antimicrobial MicroClave by inserting the luer and twisting ¼ turn, or until a friction fit is achieved.
Do not over-tighten a luer beyond the friction fit as this may damage both the luer and the Antimicrobial MicroClave.
To disconnect, grasp Antimicrobial MicroClave and then twist the mating luer counterclockwise away from Antimicrobial MicroClave until loose. Do not hold catheter hub during disconnect as this may cause accidental removal of Antimicrobial MicroClave from hub.

Administer or Aspirate

Flush After Each Use

Flush the Antimicrobial MicroClave with normal saline or in accordance with facility protocol. After blood use, the Antimicrobial MicroClave can be flushed clean and does not require change-out.
Use routine flushing in accordance with facility protocol in order to maintain catheter patency.
Change Antimicrobial MicroClave in accordance with facility protocol and CDC guidelines.
