Description

Technical Field

[0001] The utility model relates to the technical field of sample storage, in particular to a tenecteplase sample storage device. Background Art

[0002] Tenaplase is a thrombolytic drug. It is mainly used for thrombolytic therapy, especially for patients with acute myocardial infarction within 6 hours of onset, and has high value. The storage conditions of tenaplase samples are particularly strict, because slight environmental changes may affect its biological activity and stability. Therefore, the storage settings of tenaplase samples are particularly important.

[0003] The utility model patent with authorization announcement number CN218523777U discloses a biological reagent storage box, which includes a box body, a box cover rotatably mounted on the box body, a trapezoidal groove arranged on the box cover, a through hole at the bottom of the trapezoidal groove, a cooling mechanism fixedly mounted in the through hole, and a reagent rack fixedly mounted on the inner wall of the box body, the cooling mechanism includes a heat dissipation component fixed on the inner wall of the through hole, a refrigeration component fixedly mounted at the bottom of the heat dissipation component, and a refrigeration plate embedded and installed between the heat dissipation component and the refrigeration component, the refrigeration component includes a cooling plate and a U-shaped cover welded to the bottom of the cooling plate, the heat dissipation component includes a mesh tube embedded in the through hole and a heat dissipation fan and a heat conductive plate threadedly mounted from top to bottom on the inner wall of the mesh tube, and a negative pressure fan threadedly mounted between the top of the cooling plate and the bottom of the U-shaped cover. By setting up the trapezoidal groove, when multiple boxes are stacked, the trapezoidal groove ensures that the device has space for ventilation, ensuring that the cooling fan can exchange external air to take away the heat on the heat conductive plate, so as to reduce the temperature of the heat conductive plate, so that the refrigeration plate can transfer more heat, and the temperature inside the box can be reduced to a lower level, so that biological reagents such as fetuin A that need to be stored at -20°C can also be stored through the device, thereby expanding the scope of use of the biological reagent storage box.

[0004] Although the biological reagent storage box has expanded the scope of use of biological reagent storage boxes, the device still has the following problems in actual use: the device uses a refrigeration plate to cool the inside of the box, and the medium in the box that is in contact with the refrigeration plate is air. This refrigeration method has the disadvantages of low efficiency and poor refrigeration effect, and cannot meet the low-temperature storage requirements of samples. In view of this, we propose a tenaplase sample storage device. Utility Model Content

The limiting assembly 19 includes a fixed block 190 fixed to the top of the cross plate 11, and a sliding groove 1901 is provided on one side wall of the fixed block 190 close to the top plate 12. A limiting block 191 is slidably installed at the opening of the sliding groove 1901, and the limiting block 191 is pressed against the top of the top plate 12; two guide rods 192 are fixed in the sliding groove 1901, and a second spring 193 is sleeved on the guide rods 192, and a sliding hole 1911 slidingly connected to the guide rod 192 is provided on one side wall of the limiting block 191, and the second spring 193 is pressed against the limiting block 191.

[0035] As a preferred technical solution of the utility model, a connection groove 1902 is provided on the top of the fixed block 190, and a shifting block 194 is slidably installed in the connection groove 1902, and the shifting block 194 is fixedly connected to the limit block 191.

[0036] As a preferred technical solution of the utility model, the air inlet and the heat dissipation fan 18 are located on the same horizontal plane, and a blocking net 103 is installed at the air inlet. The setting of the blocking net 103 can prevent the airflow from driving foreign objects from the outside into the heat dissipation cavity 101.

[0037] As a preferred technical solution of the utility model, the cold plate 14, the fixed tube 13 and the top plate 12 are all made of alloy aluminum, and the fixed tube 13 is tightly bonded to the top plate 12 and the cold plate 14.

[0039] As a preferred technical solution of the present invention, the cross-sectional shape of the notch 110 is rectangular, and the length of the notch 110 is less than the length of the cooling plate 14. This design facilitates the cooling plate 14 to freely pass through the notch 110, and facilitates the placement and access of multiple fixed tubes 13.

The setting of the cover plate 2 plays a role in sealing and protecting the box body 10, and the setting of the connecting bolts 20 facilitates the disassembly and assembly of the cover plate 2.

[0041] It should be added that the two cooling fans 18 in this embodiment are symmetrically arranged, and the airflow directions blown by the cooling fans 18 are opposite when they are in operation. Therefore, when the two cooling fans 18 are in operation, a counter-blowing effect can be formed from both sides of the radiator 16, thereby improving the cooling effect on the radiator 16 and the semiconductor refrigeration plate 15.

[0042] When in use, the user first turns on the power of the radiator 16 and the semiconductor refrigeration sheet 15, and the radiator 16 and the semiconductor refrigeration sheet 15 start to work. The cooling surface of the semiconductor refrigeration sheet 15 cools, and the low temperature is transferred to the fixed tube 13 and the refrigerant in the interlayer 131 through the cold conduction plate 14, and the fixed tube 13 and the refrigerant are cooled, and the tenaplase sample in the fixed tube 13 is cooled at the same time; at the same time, the wind blown by the radiator 16 is blown to the multiple radiators 16, and at the same time, the heat of the heat dissipation surface of the semiconductor refrigeration sheet 15 is transferred to the radiator 16 and taken away by the wind;

[0043] When it is necessary to take out multiple fixed tubes 13, the user first pushes the shift block 194 to one side, and the shift block 194 drives the limit block 191 to slide along the slide groove 1901, and the second spring 193 is compressed. When the limit block 191 is separated from the top of the top plate 12, under the elastic action of the first spring 112, the top rod 122 moves upward and drives the top plate 12 to move upward. At this time, the user lifts the top plate 12 upward, and the top plate 12 drives the multiple fixed tubes 13 and the cold conduction plate 14 to separate from the box body 10, and the fixed tubes 13 can be removed.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
