Benefits of technology

[0014]According to the present invention, the recipient of the sample can provide the sample low-temperature storage case possible for easily confirming a good condition in quality of the sample at the time of receiving it. According to the present invention, the organism transportation supporting system possible for confirming no contamination in the sample (organism) can be provided.

Problems solved by technology

However, it has a fear of deficiency of oxygen caused by evaporating gases, and it also has a fear of outflow of refrigerant and abnormal evaporation caused by case fall or case rupture in the sample low-temperature storage case using the refrigerant for sublimating or evaporating dry ice, liquid nitrogen, or the like.
As a result, it has a problem to become a large amount of transportation costs in such a way.

first embodiment

[0042]FIG. 1 is a sectional view showing a low-temperature storage case of sample (hereinafter, referred to as a storage case) 100 relating to an embodiment of the present invention. This storage case 100 is approximately provided with a storage case 11 (storage means) for storing a sample storage case S storing a body to be cooled (sample), an introduced case 13 (introduced case of sample) attached to the storage case 11 and providing an opening 12 for putting in or out the sample storage case S in the storage case 11, a lid member 14 (closing means) closing the opening 12 of the introduced case 13, a Stirling refrigerator 15 (coldness generating means) refrigerating the sample storage case S stored in the storage case 11, and an adiabatic case 16 (adiabatic means) storing the storage case 11 and the Stirling refrigerator 15 and controlling a thermal transfer from the outside to the storage case 11 and the Stirling refrigerator 15.

[0043]The storage case 100 is provided near the ope...

second embodiment

[0091]FIG. 5 is a sectional view showing a schematic constitution of the storage case relating to a second embodiment of the present invention. FIG. 5 shows in a same manner as FIG. 2, and parts as not shown is the same as parts in FIG. 1. In points different from the storage case relating to the first embodiment, the catalytic membrane 35 containing titanium oxide (TiO2) etc. coated on a surface (upper surface) of the guide tray 21 to be a bactericidal action is used as a detection element holding member 17 and the window portion 19 as made of quarts glass etc. is provided in the lid member 14 by a wide opening area to radiate a plurality of ultraviolet rays (natural light or illumination light may be applied) on the catalytic membrane 35.

[0092]In this storage case 100a, reactive oxygen generates in a space between the lid member 14 and the guide tray 21 by radiating ultraviolet rays on the catalytic membrane 35. In case where the air containing cells etc. are infiltrated through a...

third embodiment

[0093]FIG. 6 is a sectional view showing a schematic constitution of the storage case relating to a third embodiment of the present invention. FIG. 6 shows in a same manner with FIG. 2. The parts as not shown is the same parts shown in FIG. 1. In different points between this storage case 100b and the storage 100 of the first embodiment, the catalytic membrane 35 containing titanium oxide (TiO2) etc. coated on a surface (upper surface) of the guide tray 21 to be a bactericidal action is used as the detection element holding member 17 and an ultraviolet lamp 37 is provided under the lid member 14 for radiating ultraviolet rays on the catalytic membrane 35. A power source 38 for operating the ultraviolet rays can be fixed to an upper surface etc. of the lid member 14.

[0094]When the ultraviolet rays are radiated on the catalytic rays 35 by putting on the ultraviolet lamp 37, reactive oxygen generates in a space between the lid member 14 and the guide tray 21. Thus, in case where the ai...

Abstract

The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two.

Description

TECHNICAL FIELD [0001]The present invention relates to a sample low-temperature storage case used as a low-temperature transportation and low-temperature storage of samples, and an organism transportation supporting system used therewith.BACKGROUND ART [0002]In general, when organic substance such as cells, microbes, proteins, or the like (hereinafter, referred to as “sample”) is transported from the predetermined place for storing (hereinafter, referred to as “Point A”) to the other place as used (hereinafter, referred to as “Point B”), the sample is transported in a state maintained to be low temperature in order not to deteriorate the quality of samples during transportation. As a sample low temperature storage case for such a use, the storage case with a structure, in which the vacuum adiabatic case is filled with liquid nitrogen as a refrigerant and the sample is refrigerated by this liquid nitrogen, has been known.[0003]In case of using such a sample low-temperature storage ca...
