Abstract
This paper describes development of a membrane oxygenator using a silicone hollow fiber which has a small diameter and a thin wall thickness. The hollow fiber is 300μm in outer diameter and 50μm in wall thickness.
The prototype of membrane oxygenators using the hollow fiber were developed. The membrane surface area of the oxygenators are 1.6m2 (type I) and 2.0m2 (type II). The in-vitro tests were conducted. The O2 transfer rate was 195mL/min, and the CO2 transfer rate was 161mL/min at a blood flow rate of 3L/min(typeII). The oxygenator is considered applicable to long term lung support.
