発明の名称 (英語) BLOOD ANALYSIS DEVICE AND BLOOD ANALYSIS METHOD
発明の概要(英語)

A blood analysis device for centrifugally separating plasma in a channel, wherein conveyance of blood, plasma and calibration liquid is effected within the device without using a pump or the like. The calibrator solution is reliably discharged from a sensor portion so as to make high precision analysis possible. A sensor section is provided in a plasma separating section and disposed on the side associated with a first centrifugal pressing direction as seen from a blood reservoir and a calibrator solution reservoir, while a calibrator solution waste reservoir is disposed in a second centrifugal pressing direction as seen from the plasma separating section (sensor section). The calibrator solution is conveyed to the sensor section by centrifugal operation in the first centrifugal direction.

After sensor calibration, the calibrator solution can be reliably discharged from the sensor section by effecting centrifuging in the second centrifugal direction. After the calibrator solution discharge, centrifuging is effected again in the first centrifugal direction, thereby conveying the blood in the blood reservoir to the sensor section and effecting separation of blood cells and plasma. In the case of providing a plurality of sensors, a blood introducing channel from the blood reservoir is branched downwardly of a sensor groove for communication, with the blood cells being fractionated in the branch section. The individual sensors can be isolated from each other by blood cell fraction, making higher precision analysis possible. <IMAGE>
