PURPOSE:To centrally control the registration and reference of the data on each patient by independently applying the functions identifying the patient ID and the sample type respectively to a sample container. CONSTITUTION:When a sample collected from a patient is put into a sample container 1, the bar code 2 for the patient ID is stuck to the container 1, and a holder 4 stuck with the bar code 3 for the corresponding sample type is fitted to the container 1, and the sample container l is stored in a sample container holding disk 6. These actions are repeated for sample types, the patient information such as the patient ID, name, and sex, the sample type, and analysis items corresponding to it are stored in a patient information control table and a sample type table respectively, and they are registered for each sample. When the same patient has multiple sample types, the patient information is not required to be inputted for each sample type, and only the sample type and analysis items are required to be inputted. When the bar codes 2, 3 are read by a reader 5 for each sample, the sample to be analyzed and the sample data can be correlated, and they can be centrally controlled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic analyzer equipped with a sample container holding disk, and to an automatic analyzer sample identification method for identifying a sample by an ID number.

[0002]

2. Description of the Related Art When registering a sample in an automatic analyzer having a sample container holding disk, a sample type, a sample ID number, and an analysis item are input one by one from a keyboard and stored sequentially, and then the sample is stored. The position of the sample container on the sample container holding disk is stored in the storage area corresponding to the ID number input above by sequentially reading the ID numbers attached to the sample containers contained in the container holding disk by the reader. The analyzed data is stored in a predetermined storage area. When referring to the data, it is searched by specifying the ID number of the sample and is output to the output device.

Conventionally, there is one type of sample (for example, serum), and the sample to be analyzed has been given an ID number to identify and manage the sample (ie patient). However, recently, a plurality of sample types (for example, urine and cerebrospinal fluid) have been analyzed at once, and a plurality of sample types can be analyzed for one patient. Therefore, in the automatic analyzer equipped with the sample container holding disk, the sample ID number becomes the ID of the sample sample itself (that is, the specific sample type of the specific patient), and the data management is also based on the ID of the sample sample itself. It is the current situation. In addition, as a system including the host computer, the patient computer I
Under the present circumstances, the D number and the ID number of the specimen sample itself are associated with each other to centralize the management of patient data.

In an automatic analyzer having a rack for accommodating a sample container, the type of sample is recognized by the rack as disclosed in Japanese Patent Laid-Open No. 3-255366.

[0005]

As described above, since the ID number of the sample is read and the position of the sample container holding disk is recognized, the sample having the same ID cannot be stored on the same disk. Therefore, the ID corresponds to the specimen sample itself, and the patient ID cannot be used.
Therefore, the current situation is that the management of registration and reference of multiple samples for one patient is not unified. Also,
Even in the system including the host, it is necessary for the customer to associate the patient identification number with the ID of the sample specimen itself. Therefore, an object of the present invention is to solve the above problems by taking a configuration in which the patient ID and the sample type are independently identified and data management based on the patient ID is possible.

[0006]

A feature of the present invention is that in an automatic analyzer having a sample holding disk, a sample container is provided with a patient ID and a sample type identification mark separately, and a reader for reading them is provided and read. Data from patient I
The data is stored in a data management table based on D, and management such as registration and reference of patient data can be performed based on the patient ID.

[0007]

By providing the patient ID recognition mark and the sample type recognition mark separately for one sample, it is possible to have the patient ID and sample type information separately. Therefore, when registering a plurality of samples for one patient from a keyboard or the like, it is not necessary to input patient information such as a patient ID number or patient name for each sample. Patient I when referencing patient data
By inputting D, the data of a plurality of specimens of the patient can be viewed at one time, and the technician or the like can easily make a comprehensive diagnosis of the patient. Even in a system including a host, there is no need to manage with two identification numbers, the patient ID number and the ID number of the specimen sample itself.

S1 to S6 in FIG. 6 are steps showing the analysis processing steps.

Before starting the analysis, as shown in S1,
At the time of injecting the sample into the sample container 1, the patient ID barcode label 202 is attached to the sample container 1, and the holder 204 to which the corresponding sample type barcode label 203 is attached is attached to the sample container 1 of FIG. And the sample container holding disk 6 (FIG. 2). This is repeated for the number of samples.

On the other hand, in S2, the sample to be measured is registered. From the screen shown in FIG. 4, patient information such as patient ID 4-1, name 4-2 and sex of the sample is input. These are stored as patient information in the patient information management table T-1 in FIG. Next, the sample type 4-3 is input. Analysis item groups 4-5 are displayed according to the sample type, and analysis items are selected and input. Each sample type table T-2 according to the sample type
The analysis item is stored in. This is registered for each sample. When there are a plurality of samples for the same patient, it is not necessary to input patient information for each sample, and only the sample type and analysis item need be input.

In step S3, the patient ID barcode label 202 and the sample type barcode 203 attached to the sample container 1 are read. The sample container holding disk 6 in which the sample container 1 is stored in S1 is designed to rotate sequentially, which allows the patient ID bar code label 202 and the sample to be tested one by one using the conventional bar code reader 26. Both the type barcode label 203 are read (in this case, only one reader is required). The read signal is input through the interface 16 and sequentially stored in the hard disk 24. The stored location is T- in FIG.
The position of the read sample container on the sample disk is stored in the place of the sample type table T-2 that matches the patient ID of 1 and the sample type. Thereby, the sample to be analyzed and the data of the sample are associated with each other.

The analysis is performed in S4. The sample container holding disk 6 is controlled by the microcomputer 15 via the interface 16. The sample container holding disk 6 transfers a predetermined sample to the sample dispensing position. The sample dispensing mechanism operates according to a command from the microcomputer 15 to dispense a predetermined amount of sample from the sample container 1 to the reaction container 3-2.
After dispensing, wash the sample dispensing nozzle. Next, the reaction disk 3-1 rotates so that the reaction container 3-2 into which the sample has been dispensed reaches the reagent dispensing position. In response to a command from the microcomputer 15, the reagent dispensing mechanism 10 moves to dispense and add a predetermined amount of reagent from the reagent container of the reagent disk mechanism 9 to the reaction container 3-2. After dispensing, wash the reagent dispensing nozzle. Then, the sample is rotated to the stirring position, and the stirring mechanism 11 stirs and mixes the sample and the reagent. This stirred reaction vessel 3-
When the 2 crosses the photometric position, the absorbance is measured by the multi-wavelength photometer 12. The detected absorbance signal is Log-converted, A / D-converted, and then created via the interface 16 from the absorbance of the standard sample measured by the microcomputer 15 by the analytical method designated in advance for each item. Based on the obtained calibration curve, it is converted into concentration data.
This component concentration data is used for printer 3-22 and CRT2.
At the same time that the data is output to the HDD 3, the data is stored in the hard disk 24. At the time of storage, the area of the sample type table T-2 is determined from the patient information table T-1 corresponding to the measurement sample, and the concentration data is stored in the area corresponding to the analysis item. Reaction container 3 containing the sample that has been measured
-2 moves to the position of the cleaning mechanism 14 and is used for the next analysis after cleaning. This is repeated continuously for the number of registered samples.

When it is desired to refer to the measurement result data of a certain patient, a reference display button is installed, and when the button is pressed, the screen shown in FIG. 5 is displayed. From this screen, when the ID of the patient to be referred to is input to 5-1 the information table T-1 of the patient ID that matches the ID and all sample type tables registered in it are read out, and patient information is read. The patient name is displayed as 5-2, each sample type and the analysis item corresponding to it, and the result data of each analysis item is 5-3.
Are displayed in batch. As a result, inspection engineers etc.
It is convenient to make a comprehensive patient diagnosis from the data results of a plurality of samples.

Needless to say, not only can the patient data be registered and referred to, but also the patient information can be easily changed or deleted for one patient.

In the above-mentioned embodiment, the patient ID and the sample type bar code are provided separately, but as shown in FIG. 8, one bar code is used for the sample type (a) and the patient ID (b).
The sample type and patient ID may be recognized by determining the number of digits of the barcode in advance. For example, as shown in FIG. 8 and FIG. 9, if the upper 2 digits (a) are used for the sample type and the remaining digits (b) are used for the patient ID, they are set after being read by the barcode reader. The number of digits is divided into the sample type and the patient ID, and each is recognized.

Further, as shown in FIG. 10, the position at which the sample container is installed on the sample container holding disk 6 may be set in advance for each sample type to be identified. For example, before installing the sample container on the sample container holding disk, the disk position range for each sample type is set from the screen of FIG. In FIG. 12, the disc position number obtained at the time of reading the ID barcode is subjected to the sample type determination processing according to the position range set above. The information storage table T-2 is searched by the identified sample type and the patient ID number read by the barcode reader, and the disc position is stored.

[0020]

According to the present invention described in detail above, the patient ID (ID for one patient) is stored in the sample container when two or more samples to be analyzed are executed when one analyzer is operated. By independently providing the sample type mark, it is possible to centrally perform management such as data registration and reference for each patient based on the patient ID. Thus, when registering a plurality of specimens for one patient, the technician does not have to input patient information such as patient ID and name for each specimen. It is convenient to make a comprehensive patient diagnosis from the data results of a plurality of samples.
