Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an automatic chemical analyzer that reacts a sample with a reagent and measures the concentration of a specific component in the reaction solution.

(Prior art) For example, an automatic system that uses serum collected from a human body as a sample, reacts it with a desired reagent, and then measures the concentration of a specific component in the reaction solution for diagnosis. Chemical analyzers are known. In performing such chemical analysis, reagents are selected according to the analytical items to be measured, and many types are stored in reagent containers at room temperature or in the refrigerator to suit the measurement of various items. Reagents are available outside. Information on these reagents (item, capacity, date of manufacture, lifespan, etc.) is input into an appropriate storage device via a keyboard on a console provided in the analyzer.

(Problems to be Solved by the Invention) However, in conventional analyzers, information on reagents is recorded by artificial means. Since the information is entered in the H position, there is a problem in that it is difficult to input information accurately.

For example, when inputting data via a keyboard, operators look at reagent data sheets or memo sheets before inputting data, but this often leads to data being overlooked, resulting in many mistakes. Input is often performed. In addition, inputting information is performed alternately between the keyboard surface and the sheet surface, which is time consuming and inconvenient.

The present invention has been made in response to the above-mentioned problems.
The purpose of this invention is to provide an automatic chemical analyzer that can accurately input information on reagents.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides a barcode on a reagent container that stores a reagent, and a barcode reader in the middle of the transfer route of the reagent container. It was designed to be installed.

(Function) By providing a barcode on the reagent container and installing a barcode reader midway along the transfer path of the reagent container, this barcode is read by the league whenever a reagent is required. Therefore, since the reagent information is inputted to the electric means without using artificial means, the reagent information can be inputted accurately.

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

FIG. 1 is an external view, not showing an embodiment, of an automatic chemical analyzer according to the present invention. A sample to be analyzed (not shown) is loaded into a circular sampler 1 of the analysis mechanism section A while being housed in a sample container. A 1-sample ID reader 2 is placed around the 1-non-plastic 1, and a sample dispensing arm (not shown) in which the ID of the rotated sample is placed at a desired position allows the sample to be transferred to a dilution section (not shown). sample) and diluted by sample dilution arm 4. From this dilution section, a sampling arm 3 disposed adjacent thereto performs rimple dispensing to a reaction cell (not shown) immersed in a constant temperature bath 5. Although this embodiment shows an example in which a pair of constant temperature 4fi5 is provided, their configurations are completely the same. Further, a reagent dispensing arm (not shown) is similarly arranged at a different position from the sampling arm 4 around the constant temperature bath 5, and a desired reagent is dispensed into the reaction cell. A reaction solution consisting of a sample and a reagent dispensed into the reaction cell is stirred by a stirring bar 6. The details of the sample dispensing mechanism and reagent dispensing mechanism in the reaction section around the constant temperature bath 5 are omitted because they are not directly related to the gist of the present invention, but they have the same configuration as a normal analyzer.

A reagent storage 6 is provided above the dispensing mechanism section A to store reagent containers containing reagents. - As an example, the reagent storage 6 is shown as being composed of a very warm storage 7 and a refrigerator 8. Many types of -b reagents are used depending on the analysis item, and some have different chemical properties. For this reason, a room temperature storage 7 or a refrigerator 8 can be used depending on the properties of the reagent. FIG. 2 is a perspective view showing details of the interior room 7, with the door 9 open. A large number of reagent containers 14 containing reagents can be stored in the temperature chamber 7. The reagent container 14 is provided with an item label 16 and a barcode 17, and various information about the reagent including an ID is recorded in the barcode. A barcode reader 18 is provided inside the door 9, and by turning on a switch 10 when the door 9 is opened, the reader 18 is enabled to perform a detection operation, and the reagent container is stored in or taken out from the room temperature storage 7. 14 barcodes 17 barcodes can be read. A position switch 19 is provided at the entrance end of the room temperature storage 7 and is used to define the storage position of the reagent container 14. When the door 9 is closed, it is possible to observe the internal state through the window 20 with a temperature rise of 7m7. 1
1 is a reagent pump.

The data processing section B is provided with a console 12 with a display, and is configured to allow analysis data processing by inputting various information via a keyboard 13.

Next, the operation of this embodiment will be explained.

When storing the necessary reagent containers 14 in the cold storage 7, when the door 9 is opened, the switch 10 is turned on and the barcode reader 1 is stored.
8 starts the detection operation. After predetermining the storage position of the reagent container 14 to be stored in this state using the position switch 19, the reagent container 14 is held in a position where the barcode 17 faces the barcode reader 18 and placed in the air temperature outside 7. Transport.

As a result, the information on the reagent in the reagent container 14 is read,
It is sent to the console 12 of the data processing section B together with the position switch 19 information.

According to this embodiment, since the reagent information is read and entered by electrical means, reagent information panning can be performed accurately. Therefore, it is possible to prevent erroneous inputs as in the conventional case, and also to shorten the input time, thereby making it possible to improve the efficiency of input operations.

By removing the reagent container 14 from the seedling warmer, a desired reagent can be supplied from the supply port 15 to the reagent tube prepared in advance in the reaction section.

Based on barcode data input, a means is provided to issue an alarm to the operator when the remaining reagent is below a certain level or when the expiration date of the reagent has passed. You can also do it like this.

In this embodiment, the explanation has been given by taking the air temperature outside 7 of the reagent storage 6 as an example, but the invention can be similarly applied to the refrigerator 8 as well.

[Effects of the Invention] As described above, according to the present invention, since the reagent information is inputted by electrical means, the reagent information can be inputted by n.
It can be entered accurately in one hour.
