Embodiment Construction

[0071] figure 1The device according to the invention and its individual components are shown. The device comprises a container 10 in which a flow-through system 21 is arranged. By means of a pump system, modified amniotic fluid (preferably preheated) is introduced through the connector 12 into the through-flow system 21 via the line 14 and the connecting cannula 18 . Oxygenation of the amniotic fluid can be performed through the oxygen line 16 . It is also provided that the artificial chamber inside the container can be supplied with medical breathing air through the inherent gas connection. Flow system 21 itself comprises more than 20 available O 2 and CO 2 Permeable fluid permeable element. These elements are preferably membranes arranged in layers or a plurality of small tubes with integrated micropores for gas exchange. The catheter connection for the umbilical vein catheter 32 and the two umbilical artery catheters 30.1, 30.2 to the umbilical cord 36 of the fetus is...

Abstract

The present invention relates to a device and a method for supporting a human being, preferably a newborn, in particular an extremely premature infant between the 21 / 0 and 28 / 0 week of pregnancy (SSW), comprising at least one through-flow system (21), comprising a number of fluid-permeable elements (22) and connecting elements (26, 28) for the connection to an umbilical arterial catheter (30) and an umbilical venous catheter (32) of the newborn and a through-flow lumen (20) for passing modified amniotic fluid enriched with oxygen or a oxygen-containing gas mixture through the fluid-permeable elements (22), and at least one connection (12) for introducing the modified amniotic fluid enriched with oxygen or an oxygen-containing gas mixture into the through-flow system (21), wherein the through-flow system (21) is configured in such a way that the amniotic fluid modified with oxygen or an oxygen-containing gas mixture is guided through the fluid-permeable elements (22) of the through-flow system (21) while the foetal blood is passed along the outer side of the fluid-permeable elements (22), but directed past the through-flow lumen, whereby a gas exchange occurs.

Description

technical field [0001] The present invention relates to a device and a method for life support of a human being, preferably a neonate, especially a very preterm infant of 21 / 0 to 28 / 0 weeks of gestation (SSW). Background technique [0002] Births of babies less than 24 weeks' gestation (SSW), weighing less than 500 g and without vital signs, are considered "late miscarriages" and are not statistically recorded as births. Late miscarriage affects millions of babies in developed countries around the world. Premature babies are at much higher risk of developing health complications immediately after birth or later than full-term babies. The earlier a baby is born, the less developed his organs are, and the higher the risk of health problems. 40% of very preterm infants (ie less than 28 / 0 SSW) die within the first five years (WAO report "Born to Soon", 2011). Furthermore, 91% of preterm infants born at 23 weeks of gestation and 67% of premature infants born at 24 weeks of ges...
