Description

Technical Field

[0001] This utility model relates to the field of hematology technology, and in particular to a bone marrow smear storage device for hematology. Background Technology

[0002] Hematology is a branch of internal medicine that primarily treats diseases of the hematopoietic system, i.e., blood disorders. With the continuous development of science and the interdisciplinary integration, the field of hematology is constantly expanding, and diagnostic methods are becoming increasingly sophisticated. In clinical hematology, the diagnosis of common blood disorders such as leukemia, anemia, multiple myeloma, and thrombocytopenia or thrombocytopenia all require bone marrow examination. Bone marrow examination can also be used for certain infectious diseases, such as infective endocarditis, and bone marrow culture helps improve the positive rate of diagnosis for these diseases.

[0003] Existing bone marrow smear storage devices, such as the Chinese utility model with application number 202120376499.1, use an electric telescopic rod to extend, causing the lower pressure plate to move to the bottom, which in turn moves the piston inside the lifting slot to the top. A linkage rod then guides the glass tray out of the lifting slot, facilitating the retrieval and storage of bone marrow smears. While this solves the problem of smear retrieval, it still has the following drawbacks:

[0004] 1. The structure is too complex, resulting in an excessively large storage device that cannot be transported.

[0005] 2. There is no vertical limiting mechanism, so the vertical position of the smear cannot be limited during the transfer process.

[0006] This invention addresses these issues by proposing a bone marrow smear storage device for hematology, which aims to solve the aforementioned problems. It features a simple structure, small size, and easy transport, while also facilitating the placement, removal, and fixation of smears. Utility Model Content

[0007] To address the aforementioned shortcomings in the existing technology, this utility model provides a bone marrow smear storage device for hematology.

[0008] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0009] A bone marrow smear storage device for hematology includes a box body and a box lid.

[0010] The box body is provided with a placement plate, and the placement plate is provided with a partition one and a partition two that are perpendicular to each other. The partition one and the partition two cooperate with the box body and the placement plate to form independent cavities.

[0011] A lifting plate is slidably connected below the placement plate inside the box. A lifting block is provided on the upper surface of the lifting plate at a position corresponding to the cavity. The lifting block is slidably connected to the placement plate. A height adjustment component is provided below the lifting plate inside the box. The height adjustment component adjusts the height of the lifting plate. The lifting plate pushes out the slurry in the cavity through the lifting block.

[0012] The first and second partitions are provided with limiting components, which limit the position of the smear placed in the cavity.

[0013] As an improvement, the height adjustment assembly includes an adjustment rod and a cam. The adjustment rod is rotatably connected to the lower part of the lifting plate inside the box, and the upper end of the adjustment rod is provided with a cam that fits against the lifting plate.

[0014] As an improvement, one end of the adjusting rod protrudes from the box body, and a knob is provided on the protruding end of the adjusting rod.

[0015] As an improvement, the four corners of the lower end face of the lifting plate are connected to the box body by springs.

[0016] As an improvement, the limiting component includes a first slot, a second slot, a transmission rod, and a limiting rod. The first slot is provided on one side of the partition, and the second slot is provided on the inner surface of the partition and the inner surface of the box. The second slot is connected to the first slot. The transmission rod is slidably connected in the first slot, and the limiting rod is slidably connected in the second slot. The limiting rod is connected to the transmission rod, and one end of the transmission rod protrudes from the box.

[0017] As an improvement, a positioning component is provided on the side of the box body, which fixes the position of the transmission rod.

[0018] As an improvement, the positioning component includes an end plate and a magnetic ring. The end plate is disposed on the end of the transmission rod that protrudes from the box body, and the magnetic ring is provided on the side of the box body.

[0019] Compared to traditional technologies, the advantages of this utility model are:

[0020] 1. The cam is driven to rotate by rotating the adjusting rod. The cam adjusts the height of the lifting plate. The lifting is achieved by lifting the coating in the cavity through the lifting block, which facilitates the loading and unloading of the coating. At the same time, the structure is simple, which effectively reduces the size of the device and facilitates transportation.

[0021] 2. By pushing the transmission rod, the transmission rod drives the limiting rod to move above the smear in the cavity, thereby limiting the vertical position of the smear in the cavity and ensuring that the sample on the smear will not spill during the transfer process.

[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0030] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0031] Example 1

[0032] Combined with appendix Figure 1-4 The box body 1 is provided with a placement plate 3, and the placement plate 3 is provided with a first partition 4 and a second partition 5 that are perpendicular to each other. The first partition 4 and the second partition 5 cooperate with the box body 1 and the placement plate 3 to form independent cavities.

[0033] A lifting plate 6 is slidably connected below the placement plate 3 inside the box body 1. A lifting block 7 is provided on the upper end surface of the lifting plate 6 at the position corresponding to the cavity. The lifting block 7 is slidably connected to the placement plate 3. A height adjustment component is provided below the lifting plate 6 inside the box body 1. The height adjustment component adjusts the height of the lifting plate 6. The lifting plate 6 pushes out the slurry in the cavity through the lifting block 7.

[0034] The height adjustment assembly includes an adjustment rod 8 and a cam 9. The adjustment rod 8 is rotatably connected to the lower part of the lifting plate 6 inside the box 1. The upper end of the adjustment rod 8 is provided with a cam 9, which is in contact with the lifting plate 6.

[0035] When picking up or placing the smear, rotate the adjusting rod 8, which drives the cam 9 to rotate. The cam 9 lifts the lifting plate 6, and the lifting plate 6 drives the lifting block 7 to move upward. The lifting block 7 is exposed from the placement plate 3, and the smear is removed from the lifting block 7 or placed on the lifting block 7, which facilitates the picking up and placing of the smear.

[0036] Combined with appendix Figure 1-3 The first partition 4 and the second partition 5 are provided with limiting components, which limit the position of the smear placed in the cavity;

[0037] The limiting assembly includes a first slot 12, a second slot 13, a transmission rod 14, and a limiting rod 15. The first slot 12 is provided on the side of the first partition 4, and the second slot 13 is provided on the inner surface of the second partition 5 and the box body 1. The second slot 13 communicates with the first slot 12. The transmission rod 14 is slidably connected in the first slot 12, and the limiting rod 15 is slidably connected in the second slot 13. The limiting rod 15 is connected to the transmission rod 14, and one end of the transmission rod 14 protrudes from the box body 1.

[0038] During the transfer process, the transmission rod 14 is pushed into the box 1. The transmission rod 14 moves within the slot 12 and drives the limiting rod 15 out of the slot 13. The limiting rod 15 is located above the smear in the cavity, limiting the vertical position of the smear and preventing the sample from spilling. When picking up or putting down the smear, the transmission rod 14 is pulled outward, causing the limiting rod 15 to return to the slot 13.

[0039] Example 2

[0040] Combined with appendix Figure 1-4 One end of the adjusting rod 8 protrudes from the box body 1, and a knob 10 is provided on the end of the adjusting rod 8 protruding from the box body 1;

[0041] The lifting plate 6 is connected to the box body 1 at the four corners of its lower end face by springs 11.

[0042] Based on Embodiment 1, the adjustment rod 8 can be easily rotated by the knob 10. Under the tension of the spring 11, when the cam 9 does not lift the lifting plate 6, the lifting block 7 on the upper surface of the lifting plate 6 does not protrude from the placement plate 3.

[0043] Combined with appendix Figure 1-2 The box body 1 is provided with a positioning component on its side, which fixes the position of the transmission rod 14;

[0044] The positioning component includes an end plate 16 and a magnetic ring 17. The end plate 16 is disposed on the end of the transmission rod 14 that protrudes from the box body 1, and the magnetic ring 17 is provided on the side of the box body 1.

[0045] During the transfer process, the transmission rod 14 drives the end plate 16 to move towards the box 1. The magnetic ring 17 on the side of the box 1 magnetically attracts the end plate 16, thereby fixing the position of the transmission rod 14 and then fixing the position of the limiting rod 15 to ensure the limiting effect on the coating.

[0046] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
