[0023] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figures 1 - 5 As shown, the specimen refrigerated transportation device of this embodiment includes an open-type containing bag 1 and a cover body 2 connected to the containing bag 1 and capable of covering the open mouth, the containing bag 1 includes a plurality of specimen bag monomers 3 arranged in parallel (the number of specimen bag monomers 3 is 10 in this embodiment as an example), and adjacent specimen bag monomers 3 are connected by a first flexible belt 4, the specimen bag monomers 3 include a plurality of liquid column bags 31 arranged in a circular array and a second flexible belt 32 connected between adjacent liquid column bags 31, the liquid column bag 31 is a sealed bag structure containing a refrigerant, and a plurality of liquid column bags 31 arranged in a circular array enclose a containing cavity 7 for placing a specimen 8, wherein the size of the containing cavity 7 is adapted to the outer size of the specimen 8, so that the specimen 8 can be fixed therein when placed in the containing cavity 7, and the containing bag 1 is also provided with a bottom film 9 for sealing the containing cavity 7 through the bottom.

[0025] In the above embodiment, the specimen bag monomer 3 formed by the liquid column bag and connected by the second flexible belt 32 can produce a certain deformation. When no object is placed in the accommodating cavity 7, Figure 4 and Figure 5 As shown, it is relatively flat. When the object is inserted into the accommodating cavity 7, Figure 6 and Figure 7 As shown, the accommodating cavity 7 is expanded, and a plurality of liquid column bags are wrapped around the outside of the specimen to play a shock absorbing role; a plurality of specimen bag monomers 3 are used side by side to meet the clinical demand of transporting multiple specimens at one time.

[0026] Before using the specimen refrigeration and transportation device of this embodiment, the specimen is placed in a refrigerator for several hours to cool the refrigerant therein. When the specimen needs to be refrigerated and transported, the specimen (such as a test tube with a blood sample collected) is placed in the accommodating cavity 7, and then the cover body 2 is covered. By utilizing the structure of the liquid column bag and the characteristics of the refrigerant filled therein, it can play a shock-absorbing role during the transportation process and meet the refrigeration requirements during the transportation process. The overall structure is simple, the cost is low, and the practicability is strong. In order to facilitate transportation, a handle 10 can also be provided on the cover body 2 for easy hand-carrying transportation.

[0027] In the above embodiments, the first flexible belt 4 and the second flexible belt 32 are both made of PE or PVC film belts, and the bottom film 9 is also a film belt of the same material connected to the specimen bag monomer 3. The adjacent specimen bag monomers 3 are respectively connected by their second flexible belts 32 and the first flexible belt 4 to avoid the influence of the deformation process on the adjacent specimen bag monomers 3.

[0028] In a preferred embodiment of the present utility model, the specimen bag monomer 3 and the first flexible belt 4 are of an integral structure, for example, formed by bonding two-piece PE or PVC film belts. At the first flexible belt 4 and the second flexible belt 32, the two films are bonded together, and at the liquid column bag 31, a film sealed bag is formed by bonding the ends of the two films.

[0029] In a preferred embodiment of the present utility model, one side of the cover body 2 is fixed to the accommodation bag 1 through the first connecting member, and the other side is in an openable and closable structure with the accommodation bag 1, and is fixed to the accommodation bag 1 through the second connecting member. Specifically, the first connecting member is an elastic cord 51 with both ends respectively fixed to the cover body 2 and the accommodation bag 1, and its function is to provide a margin when the length of the accommodation bag changes due to deformation; the second connecting member is an elastic cord loop 52 fixed to the cover body 2 and a fixing buckle 6 connected to the accommodation bag 1 and adapted to the elastic cord loop 52. During use, the end of the elastic cord loop 52 is sleeved on the fixing buckle 6 to complete the fixation, and the operation is simple.
