  • Patent number: 5372581
    Abstract: The present invention relates to an apparatus and a method for the withdrawal of placental blood from an umbilical cord vein. More specifically, the apparatus has a valve housing and a valve member. A needle is attached to a first port in the valve housing and a blood collection bag is attached to a second port in the valve housing. Additionally, a first syringe is attached to a third port, and a second syringe is attached to a fourth port. When the plunger on the first syringe is withdrawn it causes blood to flow from the umbilical vein through the needle and into the syringe. The valve member is then rotated, thereby sealing the needle from the blood collection bag and the syringes. Subsequently, the plunger in the second syringe, which contains an anticoagulant, is pressed. This causes the anticoagulant to mix with the blood. The blood is then stored in the attached storage bag.
