MicroClave Clear  | Neutral Displacement Connector

The Clear Choice to Help You

Visualize Connector Flushing

And Reduce the Risk of Bloodstream Infection

Intravenous (IV) therapy is essential to patient care, but accessing your patient’s bloodstream may increase the risk of infection.

The placement of an indwelling vascular access device may elevate a patient’s risk for bloodstream infection by creating a portal for bacterial entry. As a result, the design of your needlefree intravenous (IV) connectors plays a substantial role in your ability to prevent bacterial ingress and lower the risk of hospital-acquired bloodstream infections (HA-BSI).2

MicroClave’s proven needlefree IV connector technology can be an important element in your efforts to minimize the risk of bloodstream infections.

MicroClave Clear combines proven Clave® technology with a clear housing to help you visualize connector flushing after blood draws or administration while providing an effective microbial barrier against bacteria transfer and contamination.3,4,5
Ideal for a wide range of clinical applications and patient populations, MicroClave Clear is the optimal
facility-wide needlefree IV connector.

No Change in Clinical Practice or Technique

By allowing a single protocol to be used with all patient populations, MicroClave minimizes clinical training and in-servicing, while maximizing patient safety.

Use On All
Vascular Catheters

MicroClave can be used on all peripheral, arterial, and central venous catheters for blood draws or administration of IV medications.

Visualize Connector Flushing

The clear housing of the MicroClave allows for visualization of the internal fluid path upon flushing the connector.

Help Reduce Risk
of Infection

A mechanically and microbiologically closed system provides a safe and effective microbial barrier to help minimize infection risks.

Product Reference


Disinfect to Protect

  • When placing a new MicroClave Clear on a catheter, disinfect the catheter hub and prime the MicroClave Clear.
  • Before accessing a MicroClave Clear, 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

Adminster or Aspirate

  • Attach IV tubing, syringe or blood tube holder to MicroClave Clear 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 MicroClave Clear.
  • To disconnect, grasp MicroClave Clear and then twist the mating luer away from MicroClave Clear until loose. Do not hold catheter hub during disconnect as this may cause accidental removal of MicroClave Clear from hub.

Adminster or Aspirate

Flush After Each Use

  • Flush the MicroClave Clear with normal saline or in accordance with facility protocol. After blood use, the MicroClave Clear 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 MicroClave Clear in accordance with facility protocol and CDC guidelines.
