Apparatus for measuring blood cells and immunity from whole blood

In conventional apparatuses for measuring blood cells and immunity from whole blood, CRP cell is used for the final cleaning of a nozzle, and CRP measurement - cleaning of CRP cell - final cleaning of nozzle are performed in this order in the CRP cell. In contrast, in the present invention, an exclusive cleaning chamber A for immunity measurement is further provided for cleaning nozzle 36 after completion of dispensing the specimen and the reagent(s) for CRP measurement to CRP cell. Thus, a configuration is adapted wherein the outer surface and inner surface of the nozzle 36 are cleaned in the cleaning chamber A for immunity measurement while the immunity measurement is performed in CRP cell 19. Since the final cleaning of nozzle 36 is performed in parallel with the CRP measurement, the time conventionally necessary for the final cleaning of the nozzle can be shortened.
