Apparatus for measuring blood cells and immunity from whole blood

摘要

A diluted cleaning solution is contacted with the inner wall surface of an immunity measuring cell every time an immunity measurement treatment of a specimen is performed. Therefore, a diluting liquid is injected in advance, then a cleaning solution is injected, whereby a diluted cleaning solution is produced in the immunity measuring cell. As a result, the inner wall surface of the immunity measuring cell is maintained in a preferable state and the interval of the routine cleanings can be prolonged.

1. An apparatus for measuring blood cells and immunity from whole blood and performing an immunity measurement in an immunity measuring cell and counting and measuring of blood cells is performed in blood cell counting-measuring cell(s), comprising:
an immunity measuring part comprising the immunity measuring cell; a reagent container containing a latex reagent for the immunity measurement; reagent container(s) containing other necessary reagent(s) for the immunity measurement; a blood cell counting-measuring part comprising the 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 programmed to control a single sampling nozzle to move to the predetermined positions to suck and discharge a specimen and the reagent(s), and control the immunity measuring cell to perform an immunity measurement, and control the blood cell counting-measuring cell(s) to perform counting and measuring of the blood cells, a cleaning solution tank containing a cleaning solution and a cleaning agent for the aforementioned latex reagent; wherein the controller is further programmed to, every time immunity measurement of one specimen is completed in the immunity measuring cell and the specimen is discharged, control an injecting device to first inject a predetermined amount of a diluting liquid into the immunity measuring cell and then to inject a predetermined amount of the cleaning solution into the immunity measuring cell, whereby the cleaning solution diluted to a predetermined concentration contacts an inner wall surface of the immunity measuring cell, and then, control the immunity measuring cell to discharge the diluted cleaning solution.
