HEMANALYSIS APPARATUS AND METHOD OF HEMANALYSIS

摘要

A hemanalysis apparatus comprising a base plate; a hemocyte plasma separation part disposed on a lower end side of the base plate; a sensor part disposed on an upper end side of the base plate in relationship communicating with the hemocyte plasma separation part; a calibration solution reservoir disposed below the sensor part; and a waste calibration solution reservoir disposed above the sensor part. A first centrifugal axis is positioned above a hemocyte fraction accommodation portion of the hemocyte plasma separation part but below an upper end of a plasma fraction accommodation portion thereof. A second centrifugal axis is positioned inside the sensor part or at a locality proximal thereto. In the transfer/discharge of the calibration solution, the centrifugal force applied to the sensor can be reduced by carrying out low-revolution centrifugation round the first centrifugal axis remote from the sensor part. In the high-revolution centrifugal operation for hemocyte separation, the centrifugal force applied to the sensor part can be reduced by carrying out centrifugation round the second centrifugal axis. By such centrifugal operations, there can be accomplished hemocyte plasma separation and transfers of plasma and calibration solution as well as secure discharge of the calibration solution from the sensor to thereby realize high-precision analysis. Any sensor damaging attributed to strong centrifugal force at hemocyte plasma separation is avoided.
