Description

Technical Field

[0001] This utility model relates to the field of cell smear technology, and in particular to a cell smear preparation device. Background Technology

[0002] Blood smears are a common procedure in clinical laboratory testing and an essential preliminary step for observing the morphology of blood cells under a microscope.

[0003] Utility model patent application publication number 202321769627.4 discloses a cell smear preparation device, relating to the field of preparation device technology. This utility model includes a protective plate, inside which a base plate is movably mounted. The upper surface of the base plate has an anti-slip coating, and a glass slide is movably mounted on the anti-slip coating and the upper surface of the base plate. A lifting mechanism is fixedly mounted at the bottom end of the base plate. The lifting mechanism includes four evenly arranged sliding rods, the top ends of which are fixedly connected to the bottom end of the base plate. By setting a rotating handle, rotating rods, a first helical gear, and a second helical gear, rotating the handle drives the rotating rods to rotate, which in turn drives the second helical gear to rotate. The second helical gear drives a screw to rotate, causing the screw to rise and cooperate with the connecting plate to raise the four sliding rods outside the fixed rods. This adjusts the distance between the glass slide and the pusher, controls the thickness of the blood droplet spread, and allows the pusher to evenly spread the blood droplets on the glass slide.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that after the pusher spreads the blood droplets flat, it is not convenient to disassemble and clean it. This makes it easy for blood stains left over from the previous spreading to remain on the surface, resulting in uneven spreading of the blood droplets in the future and easy contamination of the blood droplets, which affects the effect of smear preparation.

[0005] Therefore, it is necessary to invent a cell smear preparation device to solve the above problems. Utility Model Content

This allows for effective smearing, resulting in more uniform smears. A plug-in rod is provided at the top for easy fixing and quick disassembly of the pusher. This allows for easy disassembly, replacement, and cleaning after each smearing operation, effectively improving the cleanliness of subsequent smearing operations. This addresses the problem in the background art where the pusher is inconvenient to disassemble and clean after spreading and flattening blood droplets, leading to residual blood stains on the surface and uneven spreading of blood droplets, which can cause contamination and affect the smear preparation effect.

[0033] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0034] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0036] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0037] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0038] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0039] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0040] like Figures 1-4 As shown, a cell smear preparation device disclosed herein may include: a base 1, a leveling component, a driving component, a mounting component, a lifting component, and a supporting component, etc.

[0041] like Figure 2 and Figure 3 As shown in this disclosure, the flattening assembly includes a push plate 52, and a plug-in rod 521 is fixedly connected to the top of the push plate 52. The mounting assembly includes a connecting rod 57, an inner groove 571 is provided on the inner side of the connecting rod 57, the plug-in rod 521 is provided on the inner side of the inner groove 571, and a fastening bolt 6 is provided on one side of the connecting rod 57. The fastening bolt 6 is threadedly connected to the inner side of the connecting rod 57 and the plug-in rod 521.

[0042] Therefore, the slope of the push plate 52 is set at 30°, and the top of the push plate 52 is fixedly connected to the plug rod 521. The plug rod 521 is inserted into the inner side of the inner groove 571 for limiting. At the same time, the plug rod 521 is fixed to the inner side of the connecting rod 57 by inserting the fastening bolt 6 into the inner side of the connecting rod 57. This facilitates the fixing of the push plate 52 and the plug rod 521, and also facilitates the quick disassembly and replacement of the push plate 52.

[0043] like Figure 3 As shown, in a preferred embodiment, the drive assembly includes a drive motor 53, which is fixedly connected to one side of the connecting plate 5. A lead screw 54 is fixedly connected to the output end of the drive motor 53. A limit block 541 is provided on the outer side of the lead screw 54.

A pressure plate 51 is fixedly connected to the bottom end of the connecting plate 5, and a pusher plate 52 is disposed at the bottom end of the pressure plate 51.

[0048] Therefore, the hydraulic cylinder 2 can effectively drive the connecting plate 5 to move up and down, thereby driving the pusher 52 at the bottom to move up and down, so that the pusher 52 is close to the glass slide 4 that needs to be coated, and then the subsequent coating work is completed.

[0049] like Figure 1 and Figure 4 As shown in this disclosure, the supporting component includes a supporting plate 3, which is fixedly connected to the top of the base 1. A groove 31 is provided on the inner side of the supporting plate 3, and a glass slide 4 is provided on the inner side of the groove 31.

[0050] Therefore, by setting up a support plate 3, two sliding grooves 31 are symmetrically arranged on the inner side of the support plate 3, which can simultaneously place two glass slides 4 for positioning, facilitating subsequent coating work. The top of the support plate 3 also has two sets of pushing components corresponding to the sliding grooves 31, which can be used for coating work independently.

[0051] like Figure 3 and Figure 4 As shown in this disclosure, the bottom end of the connecting plate 5 is provided with a groove 56, the plug rod 521 is slidably connected to the inner side of the groove 56, and one side of the connecting plate 5 is provided with a through groove 511, which is correspondingly provided with the fastening bolt 6.

[0052] Therefore, the through groove 511 can effectively tighten the fastening bolt 6, facilitate the disassembly of the fastening bolt 6, and thus facilitate the disassembly of the plug rod 521.
