A blood sample processing system and method for processing of umbilical cord blood is disclosed. The processing system is configured to ensure reliable processing of the blood sample from collection to testing, and includes a blood bag housing device, an isolation device, and a cryopreparation device. The blood bag housing device provides a secure and reliable housing for a blood sample bag while in the bucket of a centrifuge. The isolation device provides a simple and repeatable system for the isolation of the blood components separated during centrifugation. The isolated blood component sample from the isolation device is transferred into a cryobag and is ready for the administration of the cryoprotectant. The cryopreparation device provides a system with controlled temperature, ensuring precise conditions for the administration of cryoprotectant to the isolated blood component sample from the isolation device.

The present invention provides a liver hypothermic machine perfusion preservation device and a method. The device includes a perfusion loop and a controller, wherein the perfusion loop includes a main pump, a main reservoir, an auxiliary pump and an auxiliary reservoir. The main pump is connected to an inlet of the main reservoir and configured to pump a perfusate from an organ cassette into the main reservoir; an outlet of the main reservoir is connected to a portal vein and a hepatic artery of a liver, and the main reservoir is configured to supply the perfusate to the portal vein and the hepatic artery; and the auxiliary reservoir and the auxiliary pump provide an additional hepatic artery perfusion flow path. According to the present invention, for a poor internal environment of the hepatic artery, the main reservoir and the auxiliary reservoir cooperate with each other to carry out perfusion, so that the perfusion efficiency and effect of the hepatic artery can be improved. The device according to the present invention also has a molecular-sieve oxygen generation function, and a free adjustment range of oxygen concentration from 21% to 90% can be achieved by means of combined control of a molecular-sieve oxygen generation channel and an air channel, thus providing a more flexible solution for the perfusion.

Provided is a method for storing or transporting renal cells that have a high cell viability, maintain a physiological function of the kidney, and can be used as a drug evaluation system, at a temperature lower than a culture temperature. An aspect of the present invention is a method for storing or transporting renal cells, the method including a maintenance step of managing a liquid containing aggregates of the renal cells to a temperature that is a maintenance temperature and lower than a culture temperature of the renal cells and at which the liquid is not frozen.
