BLOOD TEST CONTAINER

WIPO Patent Application WO/2019/107509

A1

[Problem] To perform, with the same accuracy as current tests and using blood collected once from one blood collection tube, a test based on a blood plasma component and a test based on a blood cell component, and to enable tests to be easily performed with good accuracy even when using self-collected blood. [Solution] A blood collection bottle 1 is formed from a bottomed cylindrical container with an open distal end 3, and a separating agent 15 is applied to the inner circumferential wall thereof. A separation float 7 is movably accommodated within the blood collection bottle 1, and a cup 9 obtained by spherically notching a surface that receives blood 21 is formed on the separation float 7. The center portion of the separation float 7 is provided with a communication hole 11, and the cup 9 and a bottom surface 5a of the blood collection bottle 1 are in communication with one another via the communication hole 11. A bottom-side opening surface 13 of the blood collection bottle 1 is formed by enlarging the communication hole 11. To separate the blood 21, the separating agent 15 adheres to the bottom surface of the separation float 7 and the surface of the enlarged hole 13, and the upper portion and lower portion within the blood collection bottle 1 are thus completely hermetically sealed with the separation float 7 as a boundary therebetween. Thus, two blood components can be collected and measured with high accuracy.
