Description

Technical Field

[0001] The utility model relates to the technical field of pathological sample freezing and storage, and in particular to a pathological sample freezing and storage test tube box. Background Art

[0002] In the biomedical field, pathological samples are important tools for studying disease mechanisms, diagnosing diseases, and evaluating treatment effects. To ensure the long-term preservation and stability of pathological samples, these samples are usually stored in cryovials in liquid nitrogen or ultra-low temperature freezing equipment. These cryovials are then placed in special cryovial boxes, which are then stored in large cryovial tanks for long-term storage.

[0003] However, there is a key challenge in the existing cryopreservation management system: how to quickly and accurately identify and extract specific target cryopreservation tubes from a large number of cryopreservation tubes. The traditional approach is to attach paper or plastic labels to the side walls of cryopreservation tubes to record detailed information of pathological samples, such as sample number, collection date, pathological type, etc. However, since cryopreservation tubes are densely placed in cryopreservation test tube boxes and are usually in a frozen environment, these labels are often difficult to directly observe and read.

[0004] When it is necessary to extract the target cryotube, the operator usually needs to open the cryostat, take out the cryotube box, and then take out the cryotubes one by one to check the labels on them to determine whether they are the desired target samples. This operation method is not only inefficient and increases the workload of the operator, but also has significant risks. For example, if the cryotube is separated from the cryotube box, it will be further separated from the low-temperature environment. Repeatedly taking out and putting back the cryotube from the cryotube box will cause the sample to undergo multiple thawing and freezing processes, which is extremely detrimental to the integrity and biological activity of the sample. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a pathological sample cryopreservation test tube storage box to overcome the deficiencies in the above-mentioned prior art.

[0006] The utility model solves the above technical problems with the following technical solutions: a pathological sample cryopreservation test tube storage box, comprising an outer box body, an upper cover body, a test tube rack and an ejection mechanism; the upper cover body is rotatably arranged above the outer box body, and the test tube rack is arranged in the middle of the outer box body;

[0007] The ejection mechanism includes a telescopic cylinder, a connecting rod, and a top piece. The lower end of the telescopic cylinder is connected to the top piece through the connecting rod. A first through hole is provided in the middle of the test tube rack. A number of tube holes are circumferentially and arrayedly distributed around the first through hole on the test tube rack. The tube holes are communicated with the first through hole through notches. The size of the notches matches the size of the connecting rod so that the connecting rod can pass through the notches. A second through hole is provided in the middle of the upper cover body. The upper end of the telescopic cylinder sequentially passes through the first through hole and the second through hole.

[0008] An extension hole is provided on the upper cover body, and a number of label positions corresponding to the test tubes are provided on the peripheral wall of the outer box body.

[0009] The beneficial effects of the present utility model are as follows: When taking out the target test tube, only need to rotate the telescopic cylinder and the upper cover body so that the top piece and the extension hole correspond to the label position of the target test tube, and then lift the telescopic cylinder upward, and the top piece can eject the target test tube out of the extension hole. This storage box can quickly find and take out the target test tube, and each time only the required target test tube needs to be taken out, without exposing all the test tubes, thus avoiding the repeated freezing and thawing of all the test tubes and affecting the quality of the pathological samples.

[0026] The ejection mechanism 4 includes a telescopic cylinder 41, a connecting rod 42 and an ejection piece 43. The lower end of the telescopic cylinder 41 is connected with an ejection piece 43 through the connecting rod 42; a first through hole 31 is arranged in the middle of the test tube rack 3, and a plurality of tube holes 32 are circumferentially and arrayed around the first through hole 31 on the test tube rack 3. The tube holes 32 are communicated with the first through hole 31 through a notch 33, and the size of the notch 33 matches the size of the connecting rod 42 so that the connecting rod 42 can pass through the notch 33; a second through hole 21 is arranged in the middle of the upper cover body 2, and the upper end of the telescopic cylinder 41 sequentially passes through the first through hole 31 and the second through hole 21;

[0027] There is a protrusion hole 22 on the upper cover body 2, and a plurality of label positions 11 corresponding to the test tubes are arranged on the peripheral wall of the outer box body 1.

[0028] When taking out the target test tube, only need to rotate the telescopic cylinder 41 and the upper cover body 2 so that the top piece 43 and the protruding hole 22 correspond to the label position 11 of the target test tube, and then lift the telescopic cylinder 41 upward. The top piece 43 can then push the target test tube out of the protruding hole 22. This storage box can quickly locate and take out the target test tube, and only the required target test tube needs to be taken out each time, without exposing all the test tubes, thus avoiding the repeated freezing and thawing of all the test tubes and affecting the quality of the pathological samples.

[0029] Embodiment 2 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0030] It further includes a damping rotating shaft 44 arranged at the inner bottom of the outer box body 1. The rotating shaft of the damping rotating shaft 44 is connected with an inner rod 45. The telescopic cylinder 41 is sleeved outside the inner rod 45 and can only move along the length direction of the inner rod 45.

[0031] By setting the damping rotating shaft 44, there will be a damping feeling when rotating the telescopic cylinder 41, and it can be positioned in the rotated direction; in specific implementation, the cross-section of the inner rod 45 and the inner cavity cross-section of the telescopic cylinder 41 are both polygonal structures, so as to limit the rotation of the telescopic cylinder 41 on the inner rod 45 and only move along the length direction of the inner rod 45.
