The present invention relates to a blood centrifugation container. The invention comprises: an upper case of which the upper end is sealed by means of a sealing cap and the lower end opens downwards via a link-through port a lower case which is joined to the upper case and of which the lower end is open a rising-and-falling cap which is fitted in a way that allows position adjustment in the lower case, and which adjusts the volume inside the lower case via position adjustment relative to the lower case a first check valve which is fitted to the rising-and-falling cap and allows collected blood to pass through so as to be received in the lower case an opening-and-closing part which opens or blocks the link-through port of the lower case a second check valve for sucking out blood plasma held in the upper case and a suction tube which is provided in the inner space of the upper case, is fitted at the upper end thereof to the second check valve, and extends downwards in the length direction. The blood centrifugation container of the present invention, which is configured as described above, allows blood to be injected and suctioned even without using a syringe needle and thus the invention can be used with greater peace of mind since the risk of infection is commensurately eliminated, and the pressure of the sealed inner space can be maintained at atmospheric pressure such that blood injection and suction takes place smoothly.La présente invention concerne un récipient pour la centrifugation du sang. Linvention comprend : un boîtier supérieur dont lextrémité supérieure est scellée au moyen dun capuchon détanchéité et lextrémité inférieure souvre vers le bas par lintermédiaire dune ouverture au travers du lien un boîtier inférieur qui est lié au boîtier supérieur et dont lextrémité inférieure est ouverte un bouchon ascendant et descendant qui est fixé de manière à permettre lajustement de la position dans le boîtier inférieur, et qui ajuste le volume à lintérieur du bo
