Artificial womb system and placenta

An artificial womb system for supporting newborns, in particular extremely premature infants between the 21/0 and 28/0 week of gestation, comprising:

• a chamber of the artificial womb, said chamber being formed by an at least partially ultrasound-permeable wall and comprising a lumen for maintaining a physiologically intraamnial pressure and for receiving the artificial amniotic fluid and a newborn or a premature infant,
• at least one access configured for supplying the premature infant in the artificial womb with nutrients,
• an oxygenator and/or a gassing device for supplying oxygen to the newborn or premature infant,
• said artificial womb system configured to maintain an intraamnial pressure of >0 mbar in addition to the atmospheric pressure acting on the newborn in the chamber of the artificial womb, and to apply an oxygen containing gas mixture or O2 treatment to the amniotic fluid of the artificial womb, either before delivery into the chamber of the artificial womb, or by treatment of amniotic fluid, which is already present in the chamber of the artificial womb.
