An artificial placenta using a sheep model

我们的目的是开发一种无泵动静脉体外生命支持回路形式的人工胎盘，其中婴儿自身的血压证明了该系统。在长期仪器化胎羊的动物实验中，我们可以证明该系统可以支持气体交换并维持胎儿循环15~30小时。长期支持保证脑氧输送将需要一个基于低电阻氧合器的并联电路。

Our purpose was to develop an artificial placenta in a form of a pumpless arteriovenous extracorporeal life support circuit, in which infant's own blood pressure droved the system. In an animal experiment using the chronically instrumented fetal sheep, we could demonstrate that this system could support gas exchange and maintain fetal circulation for 15~30 hours. Prolonged support assured cerebral oxygen delivery would require a parallel circuit based on a low resistance oxygenator.
