Systems for processing and storing placenta/umbilical cord blood
First Claim
1. An assembly for processing cord blood comprisinga blood processing container,a holding container for holding a cryopreservative solution,a first tube coupling the blood processing container to a source of cord blood, the first tube having a first interior diameter, anda second tube coupling the blood processing container to the holding container, the second tube having an entire length and a second interior diameter less than the first interior diameter substantially along the entire length, the second interior diameter and the entire length restricting passage of the cryopreservative solution during gravity flow from the holding container to the blood processing container to achieve a metered flow rate without external metering instrumentality.

Abstract
Assemblies and methods process cord blood in a sterile fashion to avoid exposure to bacterial contamination. A transfer tube couples a cord blood processing container to an other container, which, in use, holds a cryopreservative solution. The transfer tube has an interior diameter that is restricted substantially along its entire length, to meter the introduction of cryopreservation solution into cord blood at a desired rate, thereby avoiding damage or trauma to the cord blood cells.
