Abstract
Es werden Verfahren und Sammlervorrichtungen zur Gewinnung von Nabelschnurblut beschrieben, bei denen Gewebe, welches das Nabelschnurblut enthaelt, in einer Kammer (10) einem Druck ausgesetzt wird, unter dessen Wirkung das Nabelschnurblut in mindestens eine Auffangeinrichtung (20) fliesst, wobei der Druck in der Kammer gleichfoermig auf die Oberflaeche des Gewebes wirkt.

 

WO2004080304 A UPAB: 20041019 NOVELTY - To take blood from the umbilical cord, to yield stem cells, the placenta is placed within a chamber under a gas pressure to force out all the blood through a pressure compensation channel into a receptacle. DETAILED DESCRIPTION - To take blood (3) from an umbilical cord, the placenta tissue (1) with the umbilical cord (2) is subjected to pressure from a gas in a chamber (10) so that the umbilical core blood flows from the tissue through an opening (11) in the chamber wall into a receptacle (20). The pressure is applied evenly to the whole tissue material in the chamber, from a compressed gas bottle or a pump (30). The blood flows through a pressure compensation channel (21) into the receptacle. USE - Blood is taken from the umbilical cord to yield stem cells for therapeutical applications. ADVANTAGE - The technique recovers a large blood volume with a total evacuation of the placenta through the pressure bearing on it in the chamber which forces out all the blood.
