3M™ Curos™ Disinfecting Port Protectors

Curos disinfecting port protectors are alcohol-containing caps that twist onto I.V. access points for disinfection and protection. Consistent use of Curos disinfecting caps on I.V. needleless connectors is associated with decreased central line associated bloodstream infections (CLABSIs).

  • Disinfects in 1 minute. Protects ports for up to 7 days.

    Each Curos disinfecting port protector contains 70% isopropyl alcohol (IPA). The IPA bathes the surfaces of the port and disinfects it in 1 minute.

All patients, all access points, all the time.

  • 3M's Curos disinfecting port protectors is the only brand on the market that has offerings to help reduce risks across all intraluminal access points.

3M™ Curos™ Disinfecting Port Protectors achieved a 99.99% reduction in 6 microbes commonly associated with CLABSI*

  • The effectiveness of Curos disinfecting port protectors was tested in vitro against**: Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, and Candida glabrata. All test samples exceeded the minimum 4-log reduction after one minute. (3M data on file.)

Advantages Over Scrubbing

The traditional standard of care in port disinfection has been a thorough manual scrub of the port with an alcohol pad, often referred to as “scrubbing the hub.“ Curos disinfecting port protectors provide several advantages over the scrub the hub protocol:

  • Nurse using Curos on patient
    Save time

    Curos alcohol-impregnated caps provide fast passive disinfection, saving nurses valuable time compared to most scrub the hub protocols. In addition, no drying time is required to achieve disinfection.

  • Curos laying on a flat surface
    Provide a physical barrier
    They provide a physical barrier to contamination between accesses, for up to 7 days.
  • Curos cap being twisted
    Remove user technique variation

    Once a Curos cap is twisted into place, it provides consistent disinfection.

  • Patient in hospital bed on Curos
    Provide visual confirmation

    Curos caps’ bright color help caregivers verify that a port is clean at a glance.

Infusion Nurses Society (INS) Infusion Therapy Standards of Practice 2021 Update

Standard 36 – Needleless Connectors
Practice Recommendation G
- Disinfect needleless connectors attached to any vascular access device (VAD) to reduce introduction of intraluminal microbes using either active or passive disinfection. Perform passive disinfection by applying a cap or covering containing a disinfection agent. Disinfection caps create a physical barrier to contamination between uses. (Level 1)
