Description

Technical Field

[0001] The present invention relates to the technical field of sample storage, and in particular to a medical laboratory test sample storage device and a storage method thereof. Background Art

[0002] In modern medical research and clinical practice, the correct storage of medical samples is crucial to ensure the accuracy and reliability of experimental results. Medical samples include blood, urine, tissue sections and other types, which need to be stored under specific conditions to maintain their biological activity and integrity. However, existing sample storage devices have some obvious shortcomings, which affect the efficiency of sample management and use.

[0003] First, when storing test tubes of different lengths, the design of traditional storage equipment often cannot adapt well to containers of different sizes. This leads to the problem of uneven heights at the top of the test tubes. When staff need to select specific samples from the storage equipment, this inconsistency in layout increases the difficulty of identification and sampling, reduces work efficiency, and may cause sample contamination or damage due to improper operation.

[0004] Secondly, in order to maintain a suitable low temperature environment to extend the shelf life of samples, many current storage solutions rely on adding refrigerants to the storage box. Although this method can provide the required cooling effect, it also brings new problems. Whenever the storage box is opened for sample access, outside air will enter the box, causing the internal temperature to rise; at the same time, the refrigerant placed inside continues to release cold energy in an attempt to restore the originally set low temperature state. This not only accelerates the consumption of the refrigerant and shortens its replacement cycle, but frequent temperature fluctuations may also have an adverse effect on the quality of highly sensitive samples. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 4 The present invention is a medical laboratory test sample storage device, comprising a storage box 1, a partition 2 is arranged in the storage box 1, the partition 2 divides the storage box 1 into an upper chamber and a lower chamber, a refrigerant is arranged in the lower chamber, both sides of the partition 2 are provided with through holes 3, a baffle 4 for shielding the through holes 3 is slidably connected in the storage box 1; a plurality of placement blocks 5 are arranged in a linear array on the top of the partition 2, a left chamber 6 is arranged inside the placement block 5, and a left opening communicating with the left chamber 6 is arranged on the top of the placement block 5; a support plate 7 is slidably connected in the left chamber 6, and a driving mechanism for driving the support plate 7 to slide along the height direction is arranged in the placement block 5;

[0032] In this embodiment, during use, when it is necessary to take or place the test tube, the baffle 4 blocks the through hole 3, thereby reducing the cold amount of the refrigerant in the lower chamber flowing out of the lower chamber, and then the test tube is placed in the left chamber 6 along the left opening, and the driving mechanism is operated to adjust the height of each support plate 7 according to the height of each test tube, so that the height of the top of each test tube is level. Compared with the prior art, the baffle 4 is used to reduce the loss of cold amount when taking or placing the test tube, and the replacement cycle of the refrigerant is delayed. At the same time, the support plate 7 with adjustable height is used to ensure that the tops of test tubes of different heights are flush, which not only improves the safety and ease of use of the sample, but also optimizes the space utilization, making the entire operation process more efficient and easy to manage.

[0033] Furthermore, the present invention is improved in that the storage box 1 is rotatably connected to a box cover 8 via a hinge, and both sides of the bottom of the box cover 8 are rotatably connected to one end of a driving rod 9, and the other end of the driving rod 9 is rotatably connected to a slider 10, such as Figure 2 As shown, the driving rod 9 is inclined; rails 11 are fixed on both sides of the inner wall of the storage box 1, and the rails 11 are arranged in the vertical direction. The slider 10 is slidably mounted on the rails 11; the baffle 4 is serrated, such as Figure 2 As shown, when the baffle 4 is staggered with the through hole 3, the through hole 3 is open, and the cold can flow out along the through hole 3. When the baffle 4 overlaps with the through hole 3, the baffle 4 blocks the through hole 3 to reduce the outflow of cold. The baffle 4 is fixed with a fixing plate 12, and the fixing plate 12 is provided with a guide hole, and the guide hole includes an inclined section 13. The slider 10 is fixedly connected with a guide shaft 14, and the guide shaft 14 passes through the inclined section 13. Figure 2As shown, when the box cover 8 is completely closed, the guide shaft 14 is at the bottom end of the inclined section 13, and there is an angle between the inclined section 13 and the moving track of the slider 10 and the guide shaft 14;

[0034] In this embodiment, when in use, when it is necessary to store or retrieve the test tubes, the box cover 8 is first opened. As the box cover 8 is opened, the driving rod 9 drives the slider 10 to move upward along the track 11. Since the slider 10 is connected to the guide shaft 14, and the guide shaft 14 passes through the inclined section 13 in the fixed plate 12 fixed on the baffle 4, when the slider 10 moves upward, the guide shaft 14 moves in the inclined section 13, prompting the baffle 4 and the fixed plate 12 to translate to one side, so that the baffle 4 overlaps with the through hole 3 on the partition 2, thereby closing the through hole 3 and not allowing the cold in the lower chamber to flow into the upper chamber; after the test tubes are taken and placed, the box cover 8 is slowly closed. As the box cover 8 is closed, the driving rod 9 pushes the slider 10 to move downward, and the guide shaft 14 moves downward along the inclined section 13, so that the baffle 4 translates to the initial position again, and the through hole 3 is released again to provide coldness to the storage box 1.

[0035] Furthermore, the present invention is improved in that the guide hole includes a vertical section 15 connected to the inclined section 13, and the vertical section 15 is parallel to the moving track of the guide shaft 14;

[0036] In this embodiment, if Figure 3 As shown, the vertical section 15 is above the inclined section 13. When the box cover 8 is opened, the driving rod 9 drives the slider 10 to move upward along the track 11. Since the slider 10 is connected to the guide shaft 14, the guide shaft 14 passes through the inclined section 13 and the vertical section 15 successively. When passing through the vertical section 15, the moving trajectory of the vertical section 15 coincides with that of the guide shaft 14, and will not affect the positions of the fixed plate 12 and the baffle 4. In summary, when the box cover 8 is opened, the baffle 4 moves first and then stops.

[0037] Furthermore, the present invention is improved in that a fixing rod 16 is fixed to the inner wall of the storage box, and the fixing plate 12 is slidably connected to the fixing rod 16. Figure 3 As shown, the sliding stability of the fixing plate 12 is improved by providing the fixing rod 16 .

[0038] Further, the present invention is improved in that the driving mechanism includes one end of a power rod 17 rotatably connected to the bottom of the support plate 7, the other end of the power rod 17 is rotatably connected to one end of a power rod 2 18, and the other end of the power rod 2 18 is fixed with a driving shaft 19, such as Figure 4As shown, the power rod 17 and the power rod 2 18 form a V shape, and the driving shaft 19 is rotatably connected to the inner wall of the left chamber 6; a worm gear 20 is fixed at one end of the driving shaft 19, a right chamber 21 is arranged inside the placement block 5, and a right opening communicating with the right chamber 21 is arranged at the top of the placement block 5, a connecting shaft 22 is rotatably connected in the placement block 5, and the two ends of the connecting shaft 22 are respectively located in the left chamber 6 and the right chamber 21, and a worm 23 meshing with the worm gear 20 is fixedly connected to the connecting shaft 22; a rotating shaft 24 is rotatably connected in the right chamber 21, and the bottom end of the rotating shaft 24 is transmission-connected to the connecting shaft 22 through a bevel gear set 25, and a hexagonal groove is provided at the top of the rotating shaft 24; a protrusion 26 is fixed to the inner wall of the left chamber 6, and the support plate 7 is slidably connected to the protrusion 26;

[0039] In this embodiment, a hexagonal wrench or other suitable tool is inserted into the hexagonal groove at the top of the rotating shaft 24 in the right opening, and the hexagonal wrench is rotated to drive the rotating shaft 24 to rotate. Since the rotating shaft 24 and the connecting shaft 22 are connected by the bevel gear set 25, the rotation of the rotating shaft 24 will be converted into the rotation of the connecting shaft 22; the worm 23 on the connecting shaft 22 rotates accordingly, and drives the driving shaft 19 to rotate through the engagement with the worm wheel 20; the rotation of the driving shaft 19 drives the power rod 17 to rotate, so that the V-shaped structure formed by the power rod 17 and the power rod 2 18 is deformed, and then pushes or pulls the support plate 7 to slide up and down along the fixed protrusion 26 on the inner wall of the left chamber 6, and the support plate 7 can be adjusted to a suitable position and pulled out. Since the worm wheel 20 and the worm 23 are provided, the adjustment of the support plate 7 has a self-locking function.

[0040] A storage method for a medical laboratory test sample storage device of the present invention comprises the following steps:

[0041] Open the box cover 8. During the opening process of the box cover 8, the shielding sheet automatically shields the through hole 3 to reduce the dissipation of cold air;

[0042] Place the test tube containing the sample into the left chamber 6;

[0043] According to the height of the test tubes, extend the handle into the hexagonal groove and rotate the shaft 24 to adjust the height of the support plate 7 so that the top of each test tube is level;

[0044] Then close the box cover 8.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
