APPARATUS FOR MEASURING BLOOD CELLS AND IMMUNITY FROM WHOLE BLOOD

摘要

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

主权项

1. An apparatus for measuring blood cells and immunity from whole blood, comprising: an immunity measuring part comprising an immunity measuring cell; reagent container(s) containing reagent(s) for the immunity measurement; and a blood cell counting-measuring part comprising blood cell counting-measuring cell(s);
wherein the immunity measuring part, the reagent container(s) and the immunity measuring part are placed at predetermined positions, and wherein the apparatus is configured such that a single sampling nozzle moves to the predetermined positions and moves downwardly and upwardly to suck and discharge a specimen and the reagent(s), and an immunity measurement in the immunity measuring cell and counting and measuring of the blood cells in the blood cell counting-measuring cell(s) are performed, the apparatus further comprising: a cleaning chamber for immunity measurement exclusively for finally cleaning the sampling nozzle after completion of dispensing the specimen and the reagent(s) to the immunity measuring cell(s); and a control configuration such that an outer surface and an inner surface of the sampling nozzle are cleaned in the cleaning chamber for immunity measurement, while the immunity measurement in the immunity measuring cell is performed.
