Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sample cold storage container for general samples and frozen samples.

(Prior art and its problems) For clinical test samples, it is necessary to keep the temperature below a certain temperature and transport it to a test center in consideration of the influence of temperature change on the sample. Therefore, a cooler box, a refrigerator, or the like is arranged in the transport vehicle so as to have a cooling function so that the sample is not affected by the temperature change.

However, since the sample is stored in the test tube, it is necessary to cool and transport the sample together with the test tube stand, which requires a lot of space, increases equipment costs, and is troublesome to handle.

On the other hand, it is desirable to keep the supernatant serum in a refrigerated storage state even during dispensing after the sample separation test, but since there is no suitable cold storage container, it is left at room temperature and strict test results are required. Not desirable under the current circumstances. Further, in a large hospital, after collecting blood in a treatment room and conducting a test in an examination room collectively, it is desirable not to affect the temperature change so as not to be affected by the change over time after blood collection, but it is preferable that the temperature change is 20 to 30,000. There is no facility to keep the sample in a cold state, and it is inevitably left at room temperature.

(Object of the Invention) The present invention aims to provide a container suitable for storing general samples, frozen samples, etc. in a sample cold storage state and for storage until testing.

Conventionally, as disclosed in Japanese Utility Model Publication No. 58-1499, canned beer and a refrigerant storage body are stood up and stored in a heat-insulating container having an open top, and the top opening is closed with a heat-insulating lid. Cold bag, made in Shokai 60-3826
As disclosed in Japanese Patent Publication No. 6, a packaging container for transportation in which a packaging body of food or the like is tightly stored in a heat-insulating container having a storage recess with an upper surface opened, and the upper surface opening is closed with a heat insulating lid. , Etc. are known.

Therefore, it is conceivable that the test tube rack itself is provided with a cooling function by utilizing such a structure. However, in the structure described in the conventional publication, due to the nature of the packaging body such as canned beer and food, in order to keep cold for a long time after storing canned beer or the like in a container, it is necessary to seal with a lid, If the above-mentioned structure is adopted for the test tube stand that needs to keep 30,000 samples in cold storage one after another, it is necessary to remove the lid each time the test tube containing the sample is stored, and the workability is very high. It gets worse and cannot be hired.

(Means for Achieving the Purpose) Therefore, the sample cold storage container according to the present invention has a structure in which “a plurality of test tube stand cylinders (2) are vertically arranged in parallel at regular intervals and integrated, Each test tube stand cylinder (2)
An opening 21 for inserting a test tube is provided in the upper part of the test tube, and the inner surface of each test tube stand cylinder (2) is formed in a shape that is in close contact with the lower end of the test tube to about 2/3 of the test tube. , The lower side of the plurality of integrated test stand cylinders (2) is surrounded and sealed with a space, and the refrigerant holding body (3) is interposed in the entire space. To do.

The refrigerant medium used in the present invention is preferably a medium that has a large heat capacity (cooling capacity) forming a fluid at least at room temperature, such as chill fast (trade name), which can be used repeatedly, but may have a cooling capacity such as water. It may be possible.

The cylindrical body holding the test tube may be in close contact with the bottom of the container, but it is better to provide a certain gap with the bottom of the container to seal the tip, and to place the refrigerant container between the tip and the bottom. It is preferable because it enhances the effect of keeping the specimen at the tip of the test tube cold.

The cool container can be made of plastic or metal such as aluminum. Although the metal is excellent in the effect of keeping cold, the manufacturing cost is high, and therefore it is preferable to manufacture it from plastic.

The form of the cold insulation container (1) is as shown in FIG.
It is convenient to handle the integrated type that seals the inside of the container without leakage of the refrigerant container to the outside of the container, but as shown in Fig. 4, place the cold container (1) in the test tube stand (2). A plurality of lids 11 arranged in parallel at a constant interval and an upper surface open container 12 for accommodating the refrigerant container may be of a separable type. In the latter case, it is necessary to devise such that the lid 11 and the lower container 12 are detachably engaged and the inside is hermetically sealed, and a medium having a large cold storage capacity that retains fluidity at the time of cooling is used as a refrigerant retaining body. Preferably.

Hereinafter, the present invention will be described in detail with reference to specific embodiments shown in the accompanying drawings.

(Embodiment) FIG. 1 shows an integrated cold-storage container (1), in which a plurality of openings 21 for inserting test tubes are arranged in parallel on the upper surface, for example, 5 rows in length and 10 rows in parallel. A cylindrical body (2) having a sealed tip extending downward is connected inside the container, and the cylindrical body (2) is disposed,
The inner surface of each tube (2) is formed in a shape that is in close contact with the lower end of the test tube to approximately 2/3 of the area to form a test tube stand, and as shown in FIG. 2, the tube (2) The space between the (2) and (2) and the space between the tip and the bottom of the container are filled with at least a refrigerant holding body (3) that is a fluid at room temperature, for example, Chill Arst (trade name), and the space is completely sealed by the outer case 10. Has been done.

As shown in FIG. 3, the cold-insulating container (1) is formed by integrally welding the cylindrical body (2) with the plastic upper body 11 and the plastic lower body 12, and heat-welding them together. Is manufactured as described above. In consideration of expansion during cooling, it is preferable to fill the refrigerant retaining body (2) so as to fill the whole as much as possible.

The cold insulation container (1) can be used repeatedly by cooling it for a predetermined time in a refrigerator or the like. Since the internal refrigerant body (3) is cooled and has a cold insulation function, if the sample test tube (4) is stored in the test tube stand tube (2) through the upper opening 21,
Due to the cooling effect of (3), the sample in the test tube (4) is kept cool at a constant temperature and is not affected by the temperature change.

(Effects of the Invention) As is apparent from the above description, according to the present invention, the refrigerant retaining body is provided in the entire enclosed space surrounding the plurality of test tube stand cylinders arranged in parallel at a constant interval. , The inner surface of the test tube stand cylinder is formed in a shape that is in close contact with the lower end of the test tube to almost 2/3 of the test tube stand so that the test tube stand has a cooling / cooling effect. By inserting into the tube stand cylinder, the sample in the test tube is hardly affected by the outside air temperature, and is sequentially cooled and kept cool without a lid, and it is possible to prevent the sample from being affected by temperature changes during transportation. .

Also, such a cool container can be used repeatedly,
Moreover, since it can be formed compactly, it does not require a space like a refrigerator, and is most suitable for placing a large number of specimens, dispensing and testing.

Furthermore, since it can be safely stored by being stored in a compact transport case, its practical value is immeasurable in the present situation where it is brought into an external testing center and clinical tests are frequently performed.

It should be noted that the cold insulation container according to the present invention can be used as a heat insulation container if the refrigerant body is used as a heat source, and since the cold insulation effect can be maintained for a long time by selecting the refrigerant body, various test tube cold insulation and Of course, it can be widely applied as a heat insulation container.
