Blood gas simulator

摘要

A test system for testing the efficiency of blood oxygenators. The system includes a deoxygenator having a mixing section, a defoaming section and a collection section. Blood and deoxygenating gas are supplied to the mixing section. Mixed blood and gas exiting the mixing section enters the defoaming section where the mixture is defoamed. A portion of the deoxygenated and defoamed blood is directed to the oxygenator under test and the remainder is directed to an overflow reservoir. Blood exiting both the oxygenator and the reservoir is recirculated to the mixing section of the deoxygenator. Test sites are provided immediately upstream and downstream of the oxygenator under test so that the condition of the blood can be checked at both points and the efficiency of the oxygenator determined.
