MicroClave Clear

MicroClave Clear

Neutral Displacement Connector

The clear choice to help you visualize connector flushing and reduce the risk of bloodstream infections.

  • Effectively clears blood and blood residual with low flush volumes.1
  • Does not require a change in clinical practice or technique.
  • Saline flush option can eliminate the use of heparin.
  • Minimal blood reflux in the catheter tip.


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.

Clinically Preferred Design.  Infection Control Performance You Can Trust.

  • 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.
