Artificial womb system and placenta

An artificial womb system for supporting newborns or premature infants between 21 and 28 weeks of gestation, comprising:

• a chamber of the artificial womb system, 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 artificial amniotic fluid and a newborn or a premature infant,
• at least one access configured for supplying the newborn or premature infant in the artificial womb system with nutrients,
• an oxygenator and/or a gassing device for supplying oxygen to the newborn or premature infant,
• a dialysis device, wherein the oxygenator and the dialysis device are connected to a port system which is configured to be connected to an umbilical cord of the newborn or premature infant, said port system comprising:
• at least two catheters configured for connecting to an umbilical vein and at least one umbilical cord artery of the newborn or premature infant, and
• a stent, which is connected to the at least two catheters for fixing the port system to the umbilical cord,
• said artificial womb system configured to maintain an intraamnial pressure of >0 mbar in addition to the atmospheric pressure acting on the newborn or premature infant in the chamber of the artificial womb system, and to apply an oxygen containing gas mixture or O2 treatment to the artificial amniotic fluid of the artificial womb system, either before delivery into the chamber of the artificial womb system, or by treatment of amniotic fluid, which is already present in the chamber of the artificial womb system.
