Problems solved by technology

However, when analyzing various samples, the assigned analysis conditions are not necessarily the conditions most suitable for the samples to be analyzed
Therefore, there is a defect that the analysis accuracy may not be sufficient if the analysis conditions are not optimal
[0007] Using the blood analyzer disclosed in U.S. Patent No. 6391263, when the reliability of the analysis results based on the detection data obtained with the set detection sensitivity is low, it is necessary to pipette the sample again and measure again
Therefore, there is a problem that the user takes the sample that needs to be measured again and performs the measurement, etc., which is cumbersome.
Although the particle analyzer disclosed in Japanese Patent Publication No. 2002-277381 describes the technology for accurately measuring a sample containing a large number of bacteria, it neither discloses nor suggests a technology for changing conditions to detect particles contained in a sample

Embodiment approach 1

[0044] FIG. 1 is a schematic perspective view of the structure of a sample analyzer according to Embodiment 1 of the present invention. As shown in FIG. 1 , the sample analyzer according to the first embodiment includes a measurement device 1 and a calculation display device 2 capable of data communication with the measurement device 1 .

[0045]The measurement device 1 and the calculation display device 2 are connected by a communication line not shown. The calculation and display device 2 controls the operation of the measurement device 1 through data communication with the measurement device 1, processes the measurement data output by the measurement device 1, and obtains analysis results. The measurement device 1 and the calculation display device 2 may be connected via a network, or may constitute a single device as a whole, and transmit and receive data through inter-process communication or the like.

[0046] The measurement device 1 detects characteristic information ...

Embodiment approach 2

[0098] The sample analyzer according to Embodiment 2 of the present invention will be specifically described below with reference to the accompanying drawings. The structure of the sample analyzer according to the second embodiment of the present invention is the same as that of the first embodiment, so the same symbols are assigned and detailed descriptions are omitted. Embodiment 2 of the present invention differs from Embodiment 1 in that instead of generating a plurality of classification data with different reduction ratios in advance, a plurality of classification data with the same reduction ratio but with different detection conditions when detecting feature information is generated .

[0099] Figure 13 It is a flowchart of the processing procedures of the controller 91 of the base control unit 9 and the CPU 21 of the calculation display device 2 of the measurement device 1 according to Embodiment 2 of the present invention. When the controller 91 of the measurement...

Abstract

The present invention provides a biological sample analyzer and computer program product which can exactly analyze the sample by selecting appropriate analyzing conditions during analyzing various samples. The sample analyzer, comprises: a sample preparing section for preparing a measurement sample from a sample and a reagent; a detector for detecting a predetermined component contained in one measurement sample prepared by the sample preparing section; and a data processing section being configured to perform operations comprising: (a) generating a plurality of analysis data for analyzing the predetermined component based on a detection result by the detector; (b) selecting one analysis data from the plurality of analysis data; (c) analyzing the predetermined component based on at least the one analysis data selected in the operation (b); and (d) outputting an analysis result obtained in the operation (c).

Description

Technical field: [0001] The invention relates to a sample analyzer and a sample analysis method for analyzing samples such as blood and urine. Background technique: [0002] Conventionally, particle analyzers that classify particles in samples such as blood and urine into multiple types of particles have been disclosed. [0003] For example, U.S. Patent Publication No. US2007 / 0111197 discloses a hematology analyzer, which stores the analysis conditions corresponding to the animal species in advance, and can change the setting to the correct one when the sample is analyzed with the wrong analysis conditions. For animal species, reanalyze the sample using analytical conditions appropriate for the changed animal species. Specifically, this hematology analyzer changes the setting range of the classification criteria for classifying particles in the particle distribution diagram according to the animal species. [0004] US Patent No. 6391263 also discloses a blood analyzer, whi...
