Problems solved by technology

[0013] However, in the conventional whole blood hematology immunoassay device, the moving speed of the sampling nozzle and the suction and discharge speed are appropriate, and each processing step is necessary, therefore, the reaction time of the reagent, the measurement time, and the cleaning frequency are not reduced room for waiting

Embodiment Construction

[0034] In the whole blood hematocyte immunoassay device described in the above-mentioned Patent Document 1, as Figure 4 with Figure 5 As shown, the sampling nozzle cleaning device configured to clean the outer surface of the sampling nozzle with a diluent is attached with the sampling nozzle. The outer surface of the sampling nozzle 36 is cleaned as necessary in each step. For cleaning, a chamber (in particular, a WBC chamber 27 for leukocyte measurement) in the blood cell count measurement unit is used. That is, the WBC chamber 27 also functions as a waste liquid chamber (funnel-shaped opening) for receiving the waste liquid and the dilution liquid from the nozzle cleaning device. The above-mentioned waste liquid etc. are transferred to the final waste liquid container ( Figure 4 18) in (a).

[0035] Although the above-mentioned Patent Document 1 does not clearly state it, generally, in the CRP chamber 19 rather than in the WBC chamber 27, the sampling nozzle (including ...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application is based on Patent Application No. 2013-093773 filed in Japan, the contents of which are incorporated herein in its entirety. technical field [0003] The present invention relates to a whole blood hematology immunoassay device comprising an immunoassay unit for automatically measuring the immunity of a blood sample and a blood cell counting unit for automatically counting and measuring blood cells such as sorting and counting blood cells. Background technique [0004] When an inflammatory reaction or tissue destruction occurs in the body, a diagnosis is made based on the detection of so-called inflammatory markers as indicators. A representative example of the marker is C-reactive protein (hereinafter referred to as CRP). CRP is a serum protein secreted into the blood by the liver and associated with ailments such as autoimmune diseases such as rheumatoid arthritis, malignant tumors, and mainly bacte...
