Description

Description: TECHNICAL FIELD The present invention relates to an automatic biochemical analysis system that issues a worksheet, processes and outputs analysis data of an analyzer set based on the worksheet.

[Conventional technology]

In recent years, a device capable of analyzing a large number of items and a large number of samples at a high speed of several hundred samples / hour has been put to practical use by improving an automatic biochemical analyzer.

First, an outline of a conventional flow of an inspection using an automatic biochemical analyzer will be described.

FIG. 4 is a diagram for explaining an outline of a conventional inspection system.

Usually, biochemical automatic analyzers require testing,
After the doctor's consultation. That is, only when the doctor examines the patient A as shown in FIG. 4, it is determined that the patient A needs to be analyzed for items such as a, b, c, d, and e. And
By instructions based on this judgment, blood collection and urine collection are performed,
Analysis of a, b, and c for serum (sample a) of patient A (A
Abc), and the analysis of d and e (Arode) is performed on the urine (sample b) of the same patient A.

Therefore, the sample and the test request item, that is, the test item, are passed to the reception of the examination room. At the reception, for example, the identification number M is given to the sample A of the patient A, and similarly, the sample B is sent to the sample B of the patient A. The identification numbers N are respectively assigned. as a result,
The analysis item abc is made to correspond to the reception number A and M,
Similarly, a worksheet for associating the analysis item de with the reception number A is issued. Then, based on this worksheet, the analysis item abc for serum A (patient A, sample A, analysis number m) for serum, and the analysis item A for urine (patient A, sample B, analysis number n) The analysis item de is set in (), and an analysis instruction is issued to the analyzer.

Since the reports of the results of the analysis performed in this way have different reception numbers, the analysis data is output for each sample as [A Mabc] and [A Nde].

[Problems to be solved by the invention]

As described above, in the conventional automatic biochemical analysis system, even if the patient is the same, different specimens are assigned different identification numbers, and each is reported as an independent analysis result. In many cases, not all of the results could be obtained.

That is, depending on the test items, desired data may be obtained by mutually calculating the results of the analysis items of different samples of the same patient. Conventionally, for such data, it has been necessary to output the analysis result once, extract necessary data again from the analysis result, and issue a predetermined calculation instruction to the extracted data. As described above, it takes time and effort because a human judgment step is involved in the middle of obtaining the data that requires calculation, and it takes a considerable amount of time to finally obtain the necessary analysis results. there were.

The present invention is to solve the above-mentioned problem, and to provide a biochemical automatic analysis system capable of obtaining final data obtained by performing an inter-item operation even when a plurality of specimens of the same patient are handled. It is intended for.

[Means for solving the problem]

To this end, the present invention provides an item developing means for developing a sample type corresponding to a test item, an analysis item, and the content of an inter-item calculation, and a developing means for each reception number when a reception number and a test item are input. Analysis setting means for setting sample types, analysis items, contents of calculation between items, and analysis numbers corresponding to each sample type, and a worksheet for creating a worksheet having information on the reception number, sample type, and analysis number Creating means, analyzing means for determining an analysis item corresponding to the analysis number set by the analysis setting means based on the analysis number of the sample cup into which the sample has been injected, and executing the analysis, and analysis data by the analysis means And data processing means for outputting, for each reception number, data obtained by performing the inter-item operation on the analysis data, wherein an analysis number set by the worksheet is provided. By setting the sample cup to said analyzing means and is characterized by being configured to output the data of the inspection items for each of the reception number.

[Action]

In the automatic biochemical analysis system of the present invention, when a reception number for identifying a patient and a test item are input, the analysis setting means sets the sample type, the analysis item, the content of the inter-item calculation, and the analysis number for each reception number. Then, a worksheet having information on the analysis number and the sample type is created by the worksheet creating means. When the analysis is performed by determining the analysis item from the analysis number by the analysis means, the analysis data and data obtained by performing an inter-item operation of the set content with respect to the analysis data are received from the data processing means by the reception number. Output every time. Therefore, by simply inputting the reception number and the test item, the data of the test item can be automatically and collectively obtained without being particularly conscious of the relationship between the subsequent analysis number, sample type, and analysis item.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an embodiment of an automatic biochemical analysis system according to the present invention, FIG. 2 is a diagram for explaining an operation procedure of the automatic biochemical analysis system, and FIG. FIG. 4 is a diagram for explaining an outline of processing in FIG.

In FIG. 1, 1 is an input unit, 2 is a worksheet creation unit, 3 is an allocation table, 4 is an allocation data file, 5 is an analyzer, 6 is an arithmetic processing unit, and 7 is an output unit.

The input unit 1 is for inputting data necessary for analysis. For example, a key input unit or a card reading unit is used. In the biochemical automatic analysis system according to the present invention, a reception number indicating a patient and its A patient's examination item (request item) is input. The allocation table 3 is a table having information in which analysis items, sample types, contents of calculation between items, and the like are developed from test items. Here, the test item is, for example, an item relating to analysis data finally required by the doctor, and the analysis item is an item corresponding to an analysis operation actually performed by the analyzer. Therefore, the test items include, for example, data obtained by directly using the results of analysis performed by the analyzer, and data obtained by performing an inter-item operation on the data of the analysis items. The worksheet creation unit 2 associates the analysis items, sample types, and the contents of the inter-item calculations developed in the allocation table 3 with the test items, assigns an analysis number to each sample type, and receives the input from the input unit 1. A worksheet is created from the information of the numbers and the inspection items, and the analysis number, the analysis items, the contents of the calculation between items, and the like are registered in the allocation data file 4 in correspondence with each reception number and the inspection items. Here, the analysis number is a number used as a reference when the analyzer performs an analysis operation, and is, for example, the number of a sample cup of the analyzer in which each sample is stored.

When receiving an analysis instruction, the analyzer 5 analyzes the analysis item registered in the allocation data file 4 by recognizing the analysis number. When the results of analysis for each item are taken in, the necessity of an inter-item operation is checked from the contents of the allocation data file 4, and if the inter-item operation is required, the operation of the designated content is performed and the operation data is output to the output unit 7. Those that are transferred and do not require inter-item calculations are those that transfer the data as it is to the output unit 7. The output unit 7 collects the data fetched through the arithmetic processing unit 6 for each reception number of the allocation data file 4, that is, for each patient and outputs the data of the examination items.

FIG. 2 shows an outline of the operation procedure of the above system.

As shown in FIG. 2, the operation procedure of the above system is as follows. I. First, an operator (analyst) inputs a reception number representing a patient and an examination item for which the doctor has instructed the patient from an input unit.

II. The system generates and outputs a worksheet with information on the analysis number, sample type, and analysis item from this test item.

III. The operator sets a sample in the analyzer based on the analysis number and the sample type of the worksheet, and issues an analysis instruction.

IV. The system performs a predetermined analysis by associating the analysis item with the analysis number, executes the calculation for items requiring inter-item calculation, and arranges and outputs the data of the inspection items for each reception number. .

Thus, between the operator and the system, when the operator inputs the reception number and the inspection item, the system creates a worksheet. Based on the worksheet, the operator sets the analyzer and gives an instruction. Is output together. The worksheet contains the patient identification number, sample type (serum, urine,
The type of processed serum, etc.) and the analysis number
The operator sees this worksheet, and is used to inject and set various samples of each patient into the sample cup of the designated analysis number (cup number).

Fig. 3 shows the flow of processing on the system side. When the system inputs the reception number and test item, the system number is required to obtain the analysis number, sample type, analysis item, and test item data. Determine the contents of the operation between items, store them in a file (memory), and output a worksheet (~
).

Here, the sample type is output on the worksheet together with the reception number as instruction information to the operator, and the contents of the analysis items and the calculation between the items are instructed to obtain test item data from the analysis result when the analysis is performed on the analyzer. The information is stored in a file together with the reception number. Therefore, subsequent instructions to the operator and the analyzer are performed using the analysis number.

When the worksheet is output, the operator injects the specified sample based on the worksheet into the sample cup of the specified analysis number, and instructs the system to start the analysis when all the samples have been injected. When receiving the analysis start instruction, the system first reads the sample cup number and recognizes the analysis number (（).

An analysis item corresponding to the analysis number recognized based on the stored information is instructed to the analyzer, and the analysis result is taken in (to
).

It checks whether there is an inter-item operation on the analysis results taken in, and performs a predetermined operation if there is an inter-item operation, and outputs the inspection item data without any inter-item operation as inspection item data for each reception number. Yes (~).

When performing an inter-item operation as described above, it is necessary to determine which analysis number result and which analysis number result are to be calculated, and which analysis number result and which inter-item operation are to be output collectively. It is files that are managed.

Next, T.CHO (total cholesterol), HDL.CHO (high-density lipid cholesterol), and H / T as test items for one reception number (a)
The case where (%) is input will be described.

In this case, T-CHO and HDL-CHO perform the same cholesterol analysis (for example, analysis items), but serum (sample type A) without pretreatment is used for T-CHO.
The processed serum (specimen type b) is used for L · CHO.
Therefore, for example, two analysis numbers N and N 'are required, and a worksheet having the analysis number and the sample type of N and N' is output. As a result, the operator sets the analysis number N for the serum before the sample B and the analysis number N 'for the serum after the sample B and issues an analysis start instruction.

According to the above instruction, the analyzer executes the analysis item when recognizing the analysis number N, and executes the analysis item similarly to recognizing the analysis number N '. When the analysis results of N and N ′ are obtained, for example,
If it is 0 or 140, H / T
(%) = 55 is obtained. Therefore, finally, T ・ CHO; 250 HDL ・ CHO; 140 HDL ・ CHO / T ・ CHOT (%) = 55 is output as data corresponding to the examination item of the patient with the reception number (a).

In this way, the reception number is a number that can identify the patient, and the test items are items designated for each patient to be examined by a doctor, such as T-CHO, HDL-CHO, GOT, GPT, serum glucose, urine glucose, etc. It is. In this way, T ・ CHO
And HDL / CHO, serum glucose and urine glucose are different test items, respectively. These are the same analysis items performed in the same measurement procedure. Therefore, even if the analysis items are the same, the sample includes serum (without pretreatment), serum (with pretreatment), urine, etc. from one patient, and an analysis number is assigned to each sample. Are collectively handled for the same sample.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the reception number, the sample type, and the analysis number are used as the output information of the worksheet. However, the analysis items, and further the patient and other information can be output to the worksheet so that the operator can recognize the analysis items. Needless to say, this may be done.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, the contents of the analysis item and the calculation between items are determined by the system only by inputting the reception number and the inspection item, and finally the calculation between the items is performed for each reception number. Thus, even if there are a plurality of specimens, related heterogeneous specimens can be automatically allocated and data can be processed. for that reason,
A quick and accurate test result can be obtained without identifying the identity of the sample and the patient or determining whether or not the calculation between items is necessary.
