CAPIOX® NX19

Oxygenator

Description

Ultra performance. No compromise.TM

​The Capiox® NX19 oxygenator with UltraPrime™ Technology is our smallest, most advanced fullsize adult oxygenator to date. Building on Terumo’s oxygenator legacy, the Capiox® NX19 oxygenator features high gas transfer utilizing new proprietary hollow fiber, enhanced gaseous microemboli (GME) removal technology, and a highly efficient heat exchanger that delivers the standard of safety1 and performance that you trust from Terumo.

By uniquely combining materials and technologies engineered to deliver Ultra performance, the Capiox® NX19 oxygenator is everything you expect in a fullsize oxygenator with the benefit of the lowest prime volume available2.

Characteristics

​Smaller hollow fiber with high efficiency

Hollow fiber is the heart of the oxygenator. With decades of experience of in-house hollow fiber development and manufacturing, Terumo now created a smaller hollow fiber with higher efficiency. This innovative hollow fiber – woven in a unique pattern – provides low priming volume and surface area reduction while delivering high gas exchange performance in combination with a lower transmembrane pressure drop.

Lower priming volume

  • Minimizes hemodilution – resulting in fewer red blood cell (RBC) transfusions, which are associated with infection, ischemic postoperative morbidity, longer hospital stays, and higher hospital costs3
  • Maintains higher hematocrit – potentially educing acute kidney injury (AKI)4,5

Less foreign surface area

  • Reduces risk of inflammatory reaction6
Highly efficient heat exchange

Terumo‘s choice of polymer material and small capillary design  increases performance in warming and cooling.2 Clinicians can be confident in the heat exchanger‘s efficiency with the benefit of low prime in a smaller device.

Innovative air removal technology

Plastic heat exchangers retain air bubbles in the spaces between the heat exchange layers. Leveraging our own hollow fiber technology, Terumo has developed a new patent-pending pre-heat-exchanger air removal technology. This technology in combination with our original self-venting technology and Prime Assist™ feature ensures excellent GME removal.

 Pre-heat-exchanger air removal technology

  • Removes air and prevents it from becoming trapped in the heat exchanger – reducing the potential for inflammatory reactions7

Proven self-venting technology and integrated arterial filter

  • Provides the safety2 of arterial filtration with less foreign surface area and no added prime volume – simplifying the circuit and assuring that the oxygenator is fully primed

Prime AssistTM feature

  • Enables easier prime – efficiently removing air without tapping and manipulation
