BD Nexiva™ Diffusics™ closed IV catheter system

Achieve performance under pressure

Contact Us

The BD Nexiva™ Diffusics™ closed IV catheter system is built upon the BD Nexiva™ closed IV catheter system with the added benefit of a diffusion catheter tip to address computed tomography (CT) challenges during power-injection procedures, without increasing the risk of IV complications.1,2

Features and Benefits

Reduced risk of infiltration / extravasation

The catheter tip features multiple teardrop-shaped holes to diffuse flow and reduce forces that can cause catheter motion in the vein by up to 67%.*3

Higher performance

The IV catheter enables higher flow rates with a smaller gauge catheter (22 to 24 G)*

Confirmed vessel entry

BD Instaflash™ needle technology incorporates a notched needle, which may improve first-stick success and reduce painful hit-and-miss insertions.

Dwell times

Proprietary BD Vialon™ biomaterial softens up to 70% in the vein, enabling longer dwell times and reducing the chance of mechanical phlebitis by up to 50%.4†

Diffusion Catheter tip

  • Features multiple teardrop-shaped holes to diffuse flow and reduce forces that can cause catheter motion in the vein by up to 67% during contrast enhanced CT procedure.
  • Enables higher flow rates on smaller gauge catheters (22 to 24 G) for power injection.*

Integrated system

  • The system features an all-in-one catheter and extension set built for your power injector's 325 psi setting.
  • An integrated closed system designed to address common CT IV challenges during power injection procedures.*
  • Needs fewer add-on devices, minimizing the number of manipulations which may lead to touch contamination and accidental disconnections.6,7 *

Stabilization platform

  • The BD Nexiva Diffusics system incorporates a built-in stabilization platform.
  • Minimizes catheter motion in the vein and not due to the built-in stabilization platform.2**

BD Instaflash™ needle technology

  • Designed to confirm immediate vessel entry.
  • Quick blood visualization may help improve insertion success and therefore reduce insertion attempts.

BD Vialon™ catheter material

  • Clinically demonstrated to dwell up to 144 hours.1
  • Reduces the chance of mechanical phlebitis by up to 50%.4†

Luer adapter

  • The system features a luer adapter with indication of maximum power injection flow rates and pressure setting.

Best practices

Increased Catheter Stabilisation

Catheter stabilisation is recognised as an intervention to decrease the risk for complications and may be advantageous in preventing catheter-related bloodstream infections (CRBSIs).6,8

Integrated Configuration

The Infusion Nurses Society recommends limiting the use of add-on devices to reduce the potential for contamination, additional manipulation, and disconnection.6

Increased Clinician Safety

98% reduced blood exposure during insertion due to the BD Nexiva Diffusics IV catheter preassembled system.5*
