Abstract
The equipment of the present invention has a plurality of storing cases in which the blood is stored and which is refrigerated by respectively provided Stirling refrigerator, in a keeping-cool room kept at a low temperature. According to the present invention, it is possible to obtain a very low temperature condition less than the recrystallization temperature of the ice in each of the storing cases, refrigerating each storing case wherein the blood is stored by each Stirling refrigerator with high performance coefficient in a very low temperature. A very low temperature condition is realized at a low cost and a high recovery is obtained, which results in that a great deal of blood is stored stably. Furthermore, taking blood in and out is carried out automatically and without the necessity of the operator's entering the keeping-cool room, by providing means for putting the blood in each storing case and taking it out from each storing case and performing the remote control of this means.
