Abstract

PURPOSE:To easily and certainly discriminate a specimen by applying bar codes showing mutually different numerical values to respective specimen receiving bags. CONSTITUTION:The specimen receiving bag 1 is formed from a resin film composed of polyethylene or polypropylene and a white solid printing region 2 is formed on the surface of the bag 1 and a bar code 3 is printed on the printing region 2. Since the bar codes 3 show mutually different continuous numerical values, respective receiving bags can be discriminated. Now, a part of produced foods is sampled as specimens to be received in the receiving bag 1 as a specimen. At this time, the bar code 3 is read by a bar code reader and inputted to a computer along with various data. Thereafter, the bar code 3 is read even at the time of the inspection of the specimen and compared with the previously inputted data to make it possible to certainly discriminate the specimen and the process on and after can be efficiently put in practice without generating a mistake.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample storage bag for storing a sample for microbial inspection of food, water, sewage, fertilizer and the like, biochemical and physiological inspection of biological tissue and the like.

[0002]

2. Description of the Related Art Conventionally, in food factories and the like, manufactured foods are appropriately sampled and stored in a sample storage bag,
Microorganisms are tested on the samples in the sample storage bag at an appropriate time. The sample storage bag used here is usually a plastic bag, and when the sample is placed in the sample storage bag, the operator labels the information (product name, manufacturing date, etc.) related to the sample. I had to write it down and attach the label to the sample bag.

[0003]

However, in such a conventional sample storage bag, in order to identify the sample placed in the sample storage bag, the operator must read the characters of the label attached to the sample storage bag. However, there is a problem that identification is troublesome and a reading error may occur.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a sample storage bag capable of easily and surely identifying the stored sample.

[0005]

In order to solve the above-mentioned problems, the present invention is characterized in that each sample bag is provided with a bar code indicating a different numerical value.

[0006]

In the sample storage bag having the above structure, the barcodes attached to the respective sample storage bags are different from each other. Therefore, when the sample is sampled and put in, the barcode attached to each sample storage bag is By reading with a bar code reader and registering it in a sample management computer, each sample can be registered separately, and when inspecting a sample, the bar code is read with a bar code reader and compared with the registered data of the computer. By doing so, the sample can be identified easily and reliably.

[0007]

Embodiments of the present invention shown in the drawings will be described below. FIG. 1 is a schematic plan view showing a sample storage bag 1 according to an embodiment of the present invention. The sample storage bag 1 is made of a resin film such as polyethylene or polypropylene in a bag shape.
A white solid printing area 2 is formed on the surface and a bar code 3 is printed on it by a printing machine or recorded by a printer. Here, as the barcode 3 attached to each of a large number of sample storage bags, those having different numerical values, preferably serial numbers, are used. Therefore, each barcode is stored by this barcode 3. It is possible to distinguish between the bags. White solid print area 2
Is much larger than barcode 3,
The area other than the portion with the bar code 3 is a writing area used for writing. In addition, a frame, an item, or the like may be printed in the writing area, if necessary.
Further, not only the bar code 3 is attached to the white solid printing area 2, but also the number indicating the numerical value of the bar code 3 may be printed or recorded and attached. If you attach numbers like this,
It is convenient for the operator to distinguish each sample storage bag by looking at the number.

The structure of the bag (shape,
The size, seal structure, film material, thickness, etc.) are arbitrary and may be appropriately determined according to the sample to be stored. The sample storage bag 1 may be used only for storing and storing the sample, or may be used when the sample is crushed by the homogenizer. When used for the latter purpose, a predetermined amount of sample is put in the sample storage bag 1 together with a predetermined amount of diluent if necessary, the sample storage bag 1 is set in a homogenizer, and the homogenizer outside the bag. Then, pressing force is repeatedly applied to crush the sample inside to make an emulsion. Therefore, when the sample storage bag 1 is used for this purpose, it goes without saying that a bag having a strength that does not cause damage or the like when a pressing force is applied to the bag from the outside is used. In addition,
If necessary, the sample storage bag 1 is disclosed in JP-A-2-176462.
Similar to the sample storage bag shown in No. 6, an elastic pad or the like that allows the internal sample to be pulled out by an injection needle or the like may be provided.

Next, a method of using the sample storage bag 1 will be described. At a food factory or the like, a part of the manufactured food is sampled as a sample and placed in the sample storage bag 1. At this time, the bar code 3 attached to each sample storage bag 1 is read by the bar code reader, registered in the sample management computer, and information (product name, production date, etc.) for the sample is input to the computer. If necessary, the necessary information is written in the white solid print area 2. Thus, the information on the sample is accumulated in the computer in correspondence with the numerical value of the barcode. After that, when performing a test of a sample (for example, a microbe test), the bar code 3 of the sample storage bag 1 is read by a bar code reader and compared with the registered data of the computer, whereby the sample can be easily and surely identified. , It is possible to operate the subsequent steps efficiently without any mistake.

Recently, the automation of the pretreatment process when conducting a microbiological examination of a specimen has progressed, and a predetermined amount of the specimen is suctioned out from the specimen storage bag, the specimen is dispensed into the culture container, and the predetermined amount into the culture container. An automated device has been developed that automatically performs pretreatment operations such as medium dispensing, mixing of sample and medium dispensed in the culture container, and dilution based on the sample processing command input in advance to the controller. There is. The sample storage bag 1 having the above-described configuration can also be suitably used for this automation device. That is,
If the information of the sample stored in each sample storage bag 1 and the instruction of the sample processing content for the sample storage bag 1 are input to the control device of the automation device together with the information of the barcode 3, the sample storage bag 1 is supplied to the automation device. The bar code 3 attached to the sample storage bag 1 when a predetermined pretreatment is performed on the internal sample
It is possible to identify the sample by reading and to automatically instruct the processing content for the sample, and based on the instruction, a predetermined pretreatment (suction of a predetermined amount of sample from the sample storage bag, transfer to a culture container) Sample dispensing, predetermined amount of medium dispensing to culture container, mixing of sample and medium dispensed to culture container, dilution, etc.) can be automatically performed.

In the above embodiment, the bar code 3 is printed or recorded directly on the sample storage bag 1, but instead of this, by attaching a label on which the bar code is printed or recorded to the sample storage bag 1, The sample storage bag 1 may be provided with a barcode. Using the label in this way has the advantage that the barcode can be printed or recorded easily. On the other hand, if a label is used, the flexibility of the labeled portion of the sample storage bag is impaired, or the label may peel off and fall off, and the barcode may disappear, but as in the illustrated embodiment, Barcode 3
If the sample is directly printed or recorded on the sample storage bag 1, the drawbacks caused by using such a label can be eliminated. Further, in the above embodiment, the sample storage bag 1
The sample storage bag of the present invention is not limited to food samples, but any object to be subjected to a microbiological test, for example, water, sewage, , Fertilizer, etc., and may be used for accommodating a sample for biochemical or physiological examination of biological tissue.

[0012]

As described above, since the sample storage bags of the present invention are provided with the bar codes indicating different numerical values, the sample storage bags need to be attached to each sample storage bag when sampling the sample. By reading the attached barcode with a barcode reader and registering it in the sample management computer, you can register each sample separately,
By reading the bar code with a bar code reader and comparing it with the registered data of the computer during the inspection of the sample, the sample can be identified easily and reliably, and the subsequent steps can be operated efficiently without error. Has the effect.
