Blood collection container

摘要

The present invention provides a blood collection container capable of allowing blood to coagulate in a short time and preventing blood from coagulating with bubbles contained therein and thus preventing formation of bubbly clots when used to collect blood therein. A blood collection container 1 stores a blood coagulation promoting agent 4 for promoting blood coagulation and an antifoaming agent 5, which is a polyoxyalkylene or a derivative thereof. The amount of the antifoaming agent 5 is 2.0×10−3 to 0.2 mg per mL of blood to be collected in the blood collection container 1.

主权项

1. A blood collection container comprising:
a tubular container having an opening at one end and a bottom at the other end opposite to the one end and a blood coagulation promoting agent (A) being a hydrolase capable of hydrolyzing the bond between arginine and any amino acid residue and/or the bond between lysine and any amino acid residue in peptide chains; and an anti foaming agent, said antifoaming agent being a polyoxyalkylene or a derivative thereof, wherein the amount of said antifoaming agent is 2.0×10−3 to 0.2 mg per mL of blood to be collected in the blood collection container, and a blood coagulation promoting agent-containing composition comprising said blood coagulation promoting agent (A) and an antifoaming agent-containing composition comprising said antifoaming agent are housed in said tubular container so that a lowermost portion of said blood coagulation promoting agent-containing composition with respect to said bottom of the tubular container is located nearer to the opening end as compared to a lowermost portion of said antifoaming agent-containing composition with respect to said bottom of the tubular container.
