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 blood cell counting-measuring part are placed at predetermined positions, and a controller configured to control 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 first cleaning chamber for blood cell count-measurement, which is for cleaning the sampling nozzle, the sampling nozzle being in a state possibly having blood thereon after dispensing for counting and measurement of the blood cells; anda second cleaning chamber for immunity measurement, which is different from the first cleaning chamber, and is a separate and dedicated 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), wherein the controller is configured to control such that a diluting liquid or a diluting liquid containing a cleaning agent fills the second cleaning chamber to a predetermined level and is discarded therefrom; the controller is configured to control such that the sampling nozzle is immersed in the diluting liquid or the diluting liquid containing the cleaning agent, and an outer surface and an inner surface of the sampling nozzle are cleaned in the second cleaning chamber for immunity measurement, by an operation of the sampling nozzle including sucking and discharging the diluting liquid supplied in the second cleaning chamber or the diluting liquid containing the cleaning agent supplied in the second cleaning chamber, while the immunity measurement in the immunity measuring cell is performed, and the controller is configured to control such that cleaning of the sampling nozzle immediately after use for immunity measurement is not performed in the first cleaning chamber, and cleaning of the sampling nozzle immediately after use for blood cell count-measurement is not performed in the second cleaning chamber.
