Patent ID: 8501112

Claim:
A body fluid analysis fixture having: a cartridge main body is provided with a container holder part that holds a liquid container for analysis that is sealed by a sealing member and is provided with a flow path through which a liquid for analysis flows; a slide body is slidably provided in the cartridge main body and slides with respect to the container holder part; and wherein the slide body is provided with a penetrating member that is configured to selectively penetrate the sealing member of the liquid container for analysis held by the container holder part, and a quantity determining capillary flow path that has a predetermined flow path volume for quantifying blood that is alternately drawn in and released from the quantity determining capillary flow path; wherein with sliding of the slide body, the penetrating member moves between a hole making position that is an upper side in an out-of-plane direction of the sealing member and a receding position that is separated from the hole making position in a direction orthogonal to the out-of-plane direction of the sealing member; and wherein the penetrating member moves to a penetrating position in order to penetrate the sealing member when the penetrating member is located in the hole making position; and wherein at the receding position the quantity determining capillary flow path is communicatively connected to a body fluid inlet to draw the blood into the quantity determining capillary flow path, and at the hole making position, the quantity determining capillary flow path is communicatively connected to the flow path through which the liquid for analysis flows for releasing the blood as the liquid for analysis to the flow path.
