Abstract
A placental blood extractor consists of an outside box having plurality of plastic bags for compressing the placenta and mounted to the top of the box. The lower part of the box has possibility to use several different circularly movable plates for mechanically facilitating the flow of the blood in the collecting veins on the fetal side of the placentas toward the central main umbilical cord vein. The box has an opening in the central lower part of the box and the lower area mechanical tray for the umbilical cord to exit the box. Blood is collected from umbilical cord and is to be collected into commercial collection bags. The area of the bag for collection of blood may be under negative pressure to facilitate the collection of blood but also gravity force may be used for that purpose. Both, the first part with the compression chambers as well as the second part, the Collector of Blood have pumps and manometers controlled by computer in their operations.
