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.
