Development of extracapillary blood flow type polyproplene hollow fiber membrane oxygenator(PHO)

comparison with HF-4000 Mera Silox, Capiox II.

Abstract

We have developed a new extracapillary blood flow type oxygenator. It consisted of a Single polypropylene hollow fiber bundle. It was compact, and prime volume was approximately 280ml, and was easy for use. And, it was low transmembrane blood phase pressure gradient. We compared PHO to HF-4000, Sit ox, Capiox II on hematologic con cequence and efficicancy of gas transfer in clinical use and compared on transmembrane blood phase pressure gradient in previous data. Then electron microscopic examination was performed in four types of hollow fiber membrane oxygenator.
