Membrane Oxygenation System (The product name)

The design of Kewei Oxygenation System aims at a reliable and consistent performance. Priming volume, surface area and pressure drop have been considered as three important parameters, which must balance against each other. 2㎡, 1.2㎡, 0.7㎡of membrane area are selected for adult type, pediatric type and infant type, giving sufficient oxygen transferring to different ranges of patients, and require low priming volumes. The integral design allows fast and easy assemblage the operation. The parallel positioning of gas exchanger and heat exchanger provides an impact structure and reduces the priming volume effectively. The360 degree rotatable inlet panel idealizes the flexibility and convenience during the operation.

 

Product Features

  • Imported hollow fiber membrane, with good O2 and CO2 transfer and less damage to blood

  • Highly efficient heat exchanger

  • Parallel design of heat-exchange chamber and gas-exchange chamber, with clear blood flow route and easy priming procedure

  • Six suction connectors which can rotate 360º, more convenient to user.

  • Low priming volume

     

Indications

It is a device used indirect-view open heart surgery under extracorporeal circulation to change venous blood to arterial blood.
