Patent ID: 7654968

Claim:
A placental blood extractor for collection of umbilical and placental blood, said blood extractor comprising: a round outside box, said box having a top section and a bottom section and having an opening in said bottom section, a plurality of inflatable compression chambers concentrically mounted within said top section and a corresponding plurality of inflatable compression chambers concentrically mounted within said bottom section, each of said compression chambers having a valve attached thereto, a sterile bag for holding a placenta, said bag being mounted between the compression chambers of said bottom section and said top section upon closure of said top and bottom sections, said sterile bag having a central closure on a first side and a leader for an umbilical cord on a second side, said leader mounted within said opening in said bottom section, a blood collection system attached to said leader, said system having a transparent, firm plastic box for insertion of the sterile collection bags for the collected blood, said collection bags having commercially available anti-coagulates for preventing coagulation of the collected blood, said box having a negative pressure to facilitate the flow of blood from the umbilical cord, a pump attached to each of said plurality of compression chambers for sequentially applying pressure to each of said concentrically mounted compression chambers within said top section and said bottom section, wherein sequentially applying pressure comprises always having the pressure in the next inwardly central compression chamber lower than in the adjacent outer compression chamber, a manometer for determining the pressure to be applied to the compression chambers, a computer for maintaining the levels of the pressure applied to different compression chambers and the time of these applied pressures as the blood is being extracted from the placenta; and for controlling the pressure within said system, and a vibrator mounted within said system for gentle shaking of said blood collection system.
