Abstract

PURPOSE:To speed up the searching of a sample data as desired and to facilitate the examination of data by making it possible to define a plurality of conditions for identifying a sample with an external input/output device in the analysis of the sample. CONSTITUTION:A screen for setting sample identifying conditions is displayed on a CRT 117. Identifying conditions are set through a keyboard 120 and undergoes a parameter conversion thereof with a computer 114. An analysis data is read out from a memory 119 to check an identification parameter attached to a data with the computer 114. When the data involved is found, it is outputted to the CRT 117.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer capable of defining a condition characterizing a sample and using the condition as a sample identification, and particularly has a storage device capable of storing a large amount of analysis results. The present invention relates to an automatic analyzer.

[0002]

2. Description of the Related Art A sample is analyzed by giving a recognizable identification of an analyzer to a sample, and from the request for analysis to the output of results, all the identifications are given. The identification that can be recognized by the analyzer is a sample number that determines the analysis order of the samples or a bar-coded label number. In the past, since the analyst was the main body, in addition to this identification, by defining the character or name that characterizes the sample, the lack of identification information was supplemented, but this is not the main reason for data retrieval. There was no data retrieval method based on numbers.

[0003]

In the above prior art, the identification number given to the sample must be taken into consideration first, and it is not easy to match the number and the sample especially when searching for data.

In the present invention, the conditions characterizing the sample are defined, and the data retrieval using the conditions is facilitated to facilitate the work of data examination and consideration, and to diversify the data retrieval method and improve the efficiency. The purpose is to plan.

[0005]

In order to achieve the above object, a screen for setting conditions for characterizing a sample is provided, and analysis is performed when the conditions are set on the screen or when the conditions have already been set. When a sample list is displayed, in order to select the analysis sample according to the condition, the setting condition is recognized and symbolized, and this is AND logic to select the target sample,
The parameters for reading from the external storage device are optimized, and the analysis result management database for editing the information that can be output on the screen is created accordingly.

[0006]

In the automatic analyzer according to the present invention, the database for managing the analysis results reads the corresponding sample from the external storage device according to the condition set in the condition setting screen characterizing the sample, and the screen displays this, When a condition is further added on the condition setting screen, the database selects the sample and reads it from the external storage device in order to cope with this.

By combining the setting conditions of the analysis sample in this way, the sample display method is diversified, the target sample can be quickly extracted, and the examination and consideration of the analysis result are facilitated.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view of the principle of the automatic analyzer. In FIG. 1, 101 is a reaction disk, and a plurality of reaction vessels 102 are installed on the concentric circumference. The reaction disk 101 is kept at a predetermined temperature by a constant temperature bath 103. Reference numeral 104 is a reagent disk, and a plurality of reagent bottles 105 containing various reagents are installed on the concentric circumference thereof. Around the reaction disk 101, a reagent dispensing probe 106, a stirring device 107,
The cleaning device 108, the light source 109, and the multi-wavelength photometer 110 are
Each is arranged. A reagent dispensing probe 111 is arranged between the reaction disc 101 and the reagent disc 104. A reagent disk 112 is installed on the circumference of rotation of the reagent dispensing probe 106 and adjacent to the reagent disk 104. All of these mechanical actions are
It is controlled by the computer 114 via the interface 113.

A plurality of sample containers 115 containing samples are installed in the sample disk 112.

The sample dispensing probe 106 includes a sample container 11
The sample contained in 5 is dispensed into the reaction container 102 by a certain amount. When the dispensing for one sample container 115 is completed, the sample disk 112 is rotated so that the next sample container 115 is located directly below the sample dispensing probe 106. The reaction container 102 into which the sample has been dispensed rotates and moves on the reaction disk 103 by the rotation operation of the reaction disk 103. Meanwhile, for the sample in the reaction vessel 102,
Dispensing the reagent in the reagent bottle 105 by the reagent dispensing probe 111, stirring the reaction solution by the stirring device 107, and the light source 1.
09 and the multi-wavelength photometer 110 are used to measure the absorbance, and the washing device 108 later cleans the reaction container 102 after the analysis. The measured absorbance signal is A /
It enters the computer 114 via the interface 113 via the D converter 116. This absorbance signal is
It is converted into concentration data of the measurement target component in the sample based on a calibration curve prepared from the absorbance signal of the standard sample solution that has been measured by an analysis method set in advance for each analysis item. The density-converted data is displayed on the screen of the CRT 117 via the interface 113 or the printer 1
It is printed out from 18 and stored in the storage device 119.

Next, a method of setting conditions for characterizing a sample according to the present invention will be described.

FIG. 2 shows an embodiment of a screen for implementing the present invention. From the five types of search condition buttons 201, the keyboard 120 is operated to select a necessary condition.
When all the selections are completed, the setting of the setting / cancel button 202 is selected, and the condition input is completed.

FIG. 3 is a processing flow chart showing a processing method for realizing the present invention. The sample search condition is set 301 via the CRT 117 and the keyboard 120. The setting conditions are stored in the storage device 11 via the interface 113.
9 is stored. After that, the condition content including the natural language setting condition is symbolized 302, and this is repeated 303 until the last condition is taken out. When all the symbolization of the condition value is completed, the analysis data stored in the storage device 119 is taken out, the optimum parameter is created 304 for efficiently checking the set condition, and the data is terminated. The data reading 305 is performed until the confirmation 306. The data is read by the sample number, but since the data has a name that characterizes the sample and the analysis date and time,
These are applied to the parameters created in 304, it is judged 307 whether or not the conditions are met, and if they are met, edit 308 is made for output. This is the end of analysis data 306
By repeating the above, it becomes possible to retrieve the analysis data corresponding to the arbitrary condition setting, and the data retrieval method becomes diversified.

[0015]

As described above, according to the present invention,
By converting the identification information of the sample, which was not conventionally used to retrieve sample analysis data, into searchable parameters, the data retrieval method is expanded from one to multiple, and the target sample can be extracted by combining the identification information. Can be done quickly,
This makes it easy to examine and consider the analysis results.
