Scientists Create the Most Successful Artificial Womb Yet
a plastic bag is a far cry from a uterus, no matter how many advanced systems it’s outfitted with. During pregnancy, a mother’s blood flows to her baby, giving the baby oxygen and clearing its lungs of carbon dioxide. This isn’t an easy process to re-create, not least because the blood pressure has to stay within a narrow range to avoid damaging the baby’s heart.
To clear these significant hurdles, researchers connected the lamb fetus’s umbilical blood vessels to an apparatus that oxygenated them. The baby’s heartbeat was able to power blood flow, eliminating the need for an external pump.
Besides the oxygenator, the Biobags have two other crucial components: continuous fluid exchange and an umbilical cord connection. Each Biobag is a single-use, closed, sterile environment, with liquid continuously flowing out of the bag to be purified—just as a mother’s kidneys would do during pregnancy.
