[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Referring to Figure 1-7 , an embodiment provided by the present utility model: a blood sample storage device, including a storage box 1, a fixing hole is provided at the inner corner of the top end of the storage box 1, as Figure 2 shown, a plurality of mounting holes 8 are provided at the top end of the storage box 1, and a test tube containing a blood sample is inserted into the mounting hole 8 to store the blood sample. A refrigeration chamber 4 is provided at the bottom of the storage box 1, and slots are provided on both sides of the top end of the storage box 1. A sealing plate is hinged at the top of the slot, and the hand rotates the sealing plate to cover the opening of the slot. The sealing plate is made of polystyrene foam plastic.

[0036] A plurality of ice bags after being frozen are respectively placed into the refrigeration chamber 4 and the slot, so that the ice bags can cool the air inside the refrigeration chamber 4 and the slot, so that the air around the mounting hole 8 is in a low-temperature state, and the blood sample in the mounting hole 8 is refrigerated through the side wall of the mounting hole 8, so that the temperature inside the mounting hole 8 is maintained at 2-10 degrees Celsius.

[0037] A cover plate 3 is hinged on one side of the refrigeration chamber 4. The cover plate 3 is made of rigid polyurethane foam insulation board. The cover plate 3 is rotated to block the refrigeration chamber 4. Since the cover plate 3 is made of rigid polyurethane foam insulation board, it can reduce the loss of cold air inside the refrigeration chamber 4 from the opening of the refrigeration chamber 4.

[0038] At the opening of the storage box 1, an inner cover 5 is connected by bolts. A plurality of through holes 6 are provided on the inner cover 5. The axes of the through holes 6 are on the same straight line as the axes of the mounting holes 8, so that the test tube containing the blood sample can pass through the through holes 6 and be inserted into the interior of the mounting holes 8, and the part of the test tube with a label pasted on the top end extends out from the interior of the through holes 6, facilitating medical staff to quickly find the required blood sample.

[0039] The inner cover 5 is fixed to the top of the storage box 1, so that the inner cover 5 can form a closed low-temperature chamber with the top of the refrigeration chamber 4. As Figure 7 shown, the test tube inserted into the interior of the mounting hole 8 is always kept inside the low-temperature chamber, so that the blood sample inside the test tube can be kept at a low temperature. Moreover, the inner cover 5 made of rigid polyurethane foam insulation board can isolate the hot air outside the storage box 1, reduce the loss of cold air inside the low-temperature chamber, reduce the heat exchange with the outside temperature, and ensure that the temperature inside the storage box 1 is relatively constant.

[0040] At the two sides of the bottom of the through hole 6, two mounting plates 11 are respectively fixedly connected. A rotating shaft 10 is fixedly connected between the two mounting plates 11. On the outer sides of both ends of the rotating shaft 10, baffle plates 7 are rotatably connected. The baffle plates 7 are made of rigid polyurethane foam insulation board. The baffle plates 7 are arranged in a semi-circular structure, and the flat surfaces of two adjacent baffle plates 7 are mutually attached to form a circular structure. The top end of the circular structure is attached to the bottom of the through hole 6 to block the through hole 6. In this embodiment, a hook groove is provided at the bottom end of the baffle plate 7, and a torsion spring 9 is wound around the outer side of the rotating shaft 10. One end of the torsion spring 9 is fixedly connected to the bottom end of the inner cover 5, and the other end of the torsion spring 9 is inserted into the hook groove. The torsion spring 9 can provide torsion for the baffle plate 7 to make the baffle plate 7 closely attached to the bottom plate of the through hole 6.

[0041] When the test tube containing blood is inserted into the interior of the mounting hole 8 through the through hole 6, the bottom of the test tube will push the baffle plate 7 to rotate downward around the rotating shaft 10, and push the torsion spring 9 to deform, so that the baffle plate 7 rotates downward to open the through hole 6, enabling the test tube containing the blood sample to pass through the through hole 6 and be inserted into the interior of the mounting hole 8. The blood test tube is inside the low-temperature chamber, realizing the low-temperature preservation of the blood sample.

[0042] After the test tube containing blood is taken out from the mounting hole 8 and the through hole 6, the torsion springs 9 on both sides of the through hole 6 will push the baffle plates 7 to rotate upward due to their own elastic force and be attached to the bottom of the through hole 6 to block the through hole 6, reducing the loss of cold air inside the storage box 1 from the mounting hole 8 (i.e., the hole of the test tube rack) and reducing the heat exchange with the external environment to ensure that the temperature inside the storage box 1 is relatively constant.

[0043] And after inserting the test tube containing the blood sample into the installation hole 8, under the action of the elastic force of the torsion spring 9 itself, the baffle 7 has a tendency to rotate upward, making the flat surface of the baffle 7 contact with the side wall of the test tube to generate a squeezing force on the test tube, so as to clamp and fix the test tube.

[0044] A box cover 2 is hinged to the top end of the storage box 1. The box cover 2 is set as a cavity structure with an opening at the bottom plate. The cavity structure of the box cover 2 enables the test tube extending out of the through hole 6 not to contact the side wall of the box cover 2 when the box cover 2 is closed, so that the box cover 2 can be closed. A heat preservation board is fixedly connected to the inner wall of the box cover 2. The heat preservation board is made of polystyrene foam plastic. The hand rotates the box cover 2 to cover the top opening of the storage box 1, reducing the loss of cold air inside the storage box 1 from the opening of the storage box 1, and the heat preservation board made of polystyrene foam plastic in the box cover 2 can improve the heat preservation effect of the box cover 2.

[0045] When it is necessary to store the blood sample, the hand rotates the box cover 2, rotates the cover plate 3 to place the ice pack into the refrigeration chamber, and also places an ice pack in the slot, then rotates the cover plate 3 again to seal the refrigeration chamber, and at the same time rotates the sealing plate to block the slot, and then passes the test tube containing the blood sample through the through hole 6 into the installation hole 8 to store the blood sample, and then rotates the box cover 2 again to cover the storage box 1.

[0046] When it is necessary to detect the blood sample inside the installation hole 8, the box cover 2 can be opened and the test tube can be taken out from the installation hole 8 and the through hole 6. At this time, the torsion spring 9 will push the baffle 7 to rotate due to its own elastic force to block the through hole 6, reducing the loss of cold air inside the storage box 1 when taking the blood sample and reducing the heat exchange with the external temperature, ensuring that the temperature inside the storage box 1 is relatively constant.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
