Further, the blood passes through the capillary valve 210 and flows into the blood cell separation chamber 20.
- the blood that has flowed into the blood cell separation chamber 20 is subjected to the action of centrifugal force and is separated into blood cells that are solid components and plasma that is a liquid component.
- the force of a part of the plasma separated in the blood cell separation chamber 20 flows into the flow channel 110. While the centrifugal force is acting, the liquid level of the plasma in the flow channel 110 is the plasma in the blood cell separation chamber 20 It is not possible to get closer to the rotation center of the panel than the liquid level. Therefore, the plasma does not reach the curved portion 11 1 closer to the panel center than the blood cell separation chamber 20.
- the plasma in the blood cell separation chamber 20 and the flow path 110 flows through the flow path 110 by the capillary force of the flow path 110. After centrifuging, go to quantification chamber 30.
- the capillary force of the flow path 110 stops working and stops.
- the panel 10 for measuring cholesterol concentration is rotated by the spindle motor 810.
- it flows into the quantitative chamber 30 after being centrifuged by the plasma force centrifugal force in the flow path 110.
- the plasma in the blood cell separation chamber 20 flows into the quantitative chamber 30 after centrifugation through the flow path 110 by the siphon effect while the centrifugal force is applied.
- the plasma in the quantification chamber 30 after centrifugation flows into the reagent holding chamber 40 in the same manner that the zero plasma flows into the quantification chamber 30 after centrifugation.
- the plasma flowing into the reagent holding chamber 40 comes into contact with the ChE layer held in the reagent holding chamber 40, dissolves the ChE layer, and the reaction of “Chemical 1” occurs.
- the spindle motor 810 is stopped to stop the rotation of the measurement panel 10, and then
- the plasma in the reagent holding chamber 40 flows into the reagent holding chamber 50 in the same manner as the plasma in the quantitative chamber 30 flows into the reagent holding chamber 40 after centrifugation. To do.
- the plasma that flows into the reagent holding chamber 50 is the ChD held in the reagent holding chamber 50.
- the ChDH layer In contact with the H layer, the ChDH layer is dissolved to cause the reaction “ii 2”.
- the spindle motor 810 is stopped to stop the measurement panel 10 from rotating.
- the reagent holding chamber 5 is in the same manner as the plasma of the reagent holding chamber 40 flows into the reagent holding chamber 50.
- the plasma flowing into the reagent holding chamber 60 is stored in the WST held in the reagent holding chamber 60.
- the WST-9 layer is dissolved to cause the reaction of “ii ⁇ 3”.
- the plasma in the reagent holding chamber 60 and the flow path 150 is measured by the capillary force of the flow path 150. It flows in the flow path 150 toward the chamber 70.
- the capillary force of the flow path 150 does not work and the plasma in the flow path 150 stops.
- the plasma in the flow path 150 flows into the large-diameter portion 152 by centrifugal force, and further It flows into the measurement chamber 70 and the waste liquid channel 80.

- the analyzer 800 moves the optical pickup 820 (see Fig. 4) parallel to the rotation surface and vertically with the feed motor 830 (see Fig. 4). Move in any direction. While moving, the optical pickup 820 irradiates the plasma in the measurement chamber 70 with a light beam, and the analyzer detects the transmitted light. From the detected transmitted light, the reaction state of the reagent is detected and analyzed.

As shown in FIG. 7, each flow path may connect the chambers linearly without forming a curved portion. When each chamber is connected with a straight flow path, the plasma is transferred using the resistance force when plasma in the chamber flows into the flow path and the centrifugal force due to the rotation of the panel.
