Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to a general specimen for clinical examination,
The present invention relates to a sample cooling rack such as a test tube containing a frozen sample or a sample for general experiment.

[0002]

2. Description of the Related Art A specimen for a clinical test usually has to be stored in a refrigerated state and transported to a test center. However, installing a car refrigerator in a transport vehicle and keeping it in a cool state has various problems in handling such as cost, space, etc., so it is often not actually implemented, and also in a cooler box etc. In many cases, the specimen is not actually kept at a predetermined temperature even after being stored.

[0003] Further, even in hospitals and the like, since a sample collected from a patient is often not actually stored in the refrigerator each time, the sample is significantly deteriorated with time and the reliability of test data is significantly reduced. There was a point.

[0004]

[Problem to be solved by the present invention]
An object of the present invention is to provide a rack suitable for preserving a test tube or the like containing a frozen sample or a sample for general experiments in a cold storage.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a rack having a cooling function which can be assembled freely and can be assembled in a desired number.

That is, according to the present invention, a plurality of recesses accommodating the lateral halves of a test tube are provided at regular intervals, (a) a hollow unit rack provided on both side surfaces, and (b) a hollow unit rack provided on one side surface. A unit rack, wherein the hollow interior can be filled with a refrigerant holding medium, and the unit racks of (a) and (b) or (a) can be combined and fixed with the concave portions facing each other. Is a sample cooling rack.

The unit rack can be manufactured by blow molding plastic. Note that the unit racks 1 and 2 described below can be manufactured using the same mold, but in that case, the opening 4 of one unit rack is attached to the opposite side.

As shown in FIG. 1, the rack of the present invention is composed of unit racks 1 and 2 having concave portions on one side and unit racks 3 having concave portions on both side surfaces, if necessary, with the concave portions facing each other. Assembled by allowing the test tube to be inserted into and securing it. When the number of test tubes is large, it is possible to further assemble the unit rack 3. Alternatively, only the unit rack 3 may be combined and fixedly used.

In order to fix the unit racks, a plate 12 as shown in FIG. 5 is adhered to the bottom surface and fixed and integrated, or the unit racks are tied with a tying string 7 and fixed and integrated.

Each unit rack is formed in a hollow shape, and is filled with a cooling medium through the opening 4, and then the opening 4 is closed with a lid, or the opening 4 is sealed by heat welding.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Unit racks 1, 3 and 2 shown in FIGS. 2, 3 and 4 are fixed and integrated as shown in FIG. The recess 14 of the unit rack 3 and the recess 15 of the unit rack 3 and the recess 1 of the unit rack 2 shown in FIG.
The spaces 6 into which the test tubes can be inserted are formed by positioning the respective tubes 6 in opposition to each other, and a test tube stand is formed.

After filling the refrigerant holding body 10 from the opening 4 of the unit racks 1, 2, and 3, the opening 4 may be sealed with a lid, or the opening 4 may be sealed by heat welding. It is desirable that the refrigerant medium has a large heat capacity showing fluidity at normal temperature, but water may be used.

In order to fix and integrate each unit rack,
The projections 8 and the depressions 9 of the seal wax are fitted so as not to be displaced from each other, and are fixed by the binding of the binding cord 7 passed through the groove 5.

Further, in order to secure the fixing, a plate 12 may be adhered to the bottom of the unit rack as shown in FIG. In the case of immobilization by such a method, depending on the purpose of use, it is not necessary to tie the seals 8, 9 and the string.

[0015]

The rack of the present invention has a cooling effect because the hollow body is filled with a cooling medium, so that the effect of a rise in the temperature of the sample during storage and transport of the sample can be avoided.

Further, since the rack can be used repeatedly and is very small, it does not require a large space like a refrigerator, which is advantageous for transportation and storage.

In addition, the combination and number of unit racks can be freely selected and freely assembled in accordance with the number of test tubes to be used, and it is possible to assemble them freely. It is economical.

The mold of the rack is more economical than the injection molding because of the inexpensive blow molding. In addition, since the thickness can be reduced by blow molding, the whole is light, economical, and advantageous in handling.

The rack is usually cooled in a refrigerator in advance and used in a heat insulating case made of a heat insulating material.
In addition to the purpose of cold storage, it can be used for the purpose of filling with hot water and storing at a high temperature, for example.
