Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a low-cost and simple coating pusher. Background Technology

[0002] Blood cell morphology examination is of great value in routine blood tests, differential diagnosis of hematologic diseases, infectious diseases, anemia, and in identifying pathogenic factors. Its applications are extremely wide, especially in the diagnosis of hematologic disorders. High-quality blood smear preparation is fundamental to blood cell morphology examination; the quality of the blood smear directly affects the examination and diagnostic results. Currently, clinical testing typically uses manual smear preparation. This involves using a scraper at a certain angle to drop blood onto the smear and spread a thin blood film. While simple, this method carries certain biological risks, and the angle and speed of the scraping are inconsistent, affecting the smear preparation and easily leading to uneven blood film thickness, cell degeneration, or rupture.

[0003] Existing similar products are characterized by their fully or semi-automatic operation, high efficiency, and good slide preparation quality. However, these devices are complex in structure and expensive, making them suitable only for large hospitals or large medical testing centers. In contrast, many primary healthcare institutions lack the financial resources to purchase such equipment and rely primarily on manual slide preparation. The result of manual blood smear preparation is inconsistent quality, which can easily affect subsequent interpretation and diagnosis. Therefore, this invention addresses the pain point of inconsistent smear quality at a low cost, making it potentially suitable for widespread adoption in primary healthcare institutions. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a low-cost and simple tablet pusher, which solves the problems of unstable tablet coating quality and high cost.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] This utility model discloses a low-cost, simple slide pusher, comprising a horizontally arranged base plate with a cover plate, an X-axis linear module fixedly mounted on the base plate, and a Z-axis linear module located on one side of the X-axis linear module. The X-axis linear module has a placement plate for placing glass slides, which slides in conjunction with the X-axis linear module. The Z-axis linear module has a rotating assembly that slides in conjunction with the Z-axis linear module. A clamp is hinged to the rotating assembly, and a slot for mounting a scraper is provided at the end of the clamp near the placement plate. During vertical movement of the rotating assembly, the lower end of the scraper contacts the glass slide.

[0007] In the above solution, by setting the clamp, the rotating component is first rotated to pre-adjust and fix the angle between the clamp and the horizontal plane. Then, the slide is placed on the placement plate, and the scraper is installed into the clamp slot. A small amount of anticoagulant blood is dripped onto the designated position on the slide. The Z-axis linear module is driven to press the clamp down. After the scraper presses onto the slide, the X-axis linear module is driven to pull the slide back slowly and then push it forward quickly. After the operation is completed, the Z-axis linear module is driven to move the clamp back to the initial position, and the slide can be removed. The slides obtained by this slide pusher have stable quality, and the slide pusher has a simple structure and high working efficiency, which helps to greatly reduce costs, thereby solving the problems of unstable slide quality and high cost.

[0008] The Z-axis linear module includes a vertically arranged column, a first slider is slidably connected to the column, a first drive mechanism is provided at the upper end of the column, and the column is connected to the output shaft of the first drive mechanism.

[0009] In the above scheme, the first driving mechanism is used to drive the first slider to slide in the vertical direction.

[0010] The rotating assembly includes a first circular plate, a second circular plate, and a third circular plate. The first circular plate is fixedly connected to the first slider. A fixing nut is provided on the first circular plate. When the fixing nut is loosened, the first circular plate and the second circular plate are rotated together. When the fixing nut is tightened, the first circular plate and the second circular plate are fixed together. The second circular plate and the third circular plate are fixed together.

[0011] In the above scheme, the rotating component is used to pre-adjust the angle between the clamp and the horizontal plane. Loosening the fixing nut and rotating the second circular plate will drive the third circular plate to rotate, thereby adjusting the angle between the clamp and the horizontal plane. The first drive mechanism is matched with the clamp and can freely select different adaptation angles to adapt to blood samples of different concentrations.

[0012] The third circular plate is provided with a horizontally arranged first rotating shaft, and the end of the chuck away from the scraper is provided with a second rotating shaft. A spring connects the first rotating shaft and the second rotating shaft, and the spring achieves hinge connection.

[0013] The above solution achieves a flexible connection between the rotating component and the chuck by using a spring.

[0014] A spring clip is provided near the edge of the end of the chuck that is close to the placement plate.

[0015] The above solution uses a spring clip to ensure that the scraper blade does not easily fall off and can be easily replaced.

[0016] The X-axis linear module includes a horizontally arranged crossbar, on which a second slider is slidably connected. A second drive mechanism is provided at one end of the crossbar, and the crossbar is connected to the output shaft of the second drive mechanism. The placement plate and the second slider are in a sliding fit.

[0017] In the above scheme, the second driving mechanism is used to drive the second slider to slide in the horizontal direction, so as to execute the pushing action in a precise and controllable manner.

[0018] The placement plate is provided with grooves.

[0019] The above scheme uses grooves to hold glass slides.

[0020] The above solution has the following advantages:

[0021] 1. The present invention provides a low-cost, simple slide pusher comprising a horizontally arranged base plate, on which an X-axis linear module is fixedly mounted. A Z-axis linear module is located on one side of the X-axis linear module. A placement plate for placing glass slides is mounted on the X-axis linear module, and the placement plate slides in contact with the X-axis linear module. A rotating assembly is mounted on the Z-axis linear module, and the rotating assembly slides in contact with the Z-axis linear module. A clamp is hinged to the rotating assembly, and a scraper is mounted at the end of the clamp near the placement plate. The slide is placed on the placement plate, and the scraper is installed in the gap of the clamp. A small amount of anticoagulant blood is dropped onto the designated position on the slide. The Z-axis linear module is driven to press the clamp down. After the scraper is pressed onto the slide, the X-axis linear module is driven to pull the slide back slowly and then push it forward quickly. After the operation is completed, the Z-axis linear module is driven to move the clamp back to the initial position, and the slide can be removed. The slides obtained by this slide pusher are of stable quality, and the slide pusher has a simple structure, high working efficiency, and helps to greatly reduce costs.

[0022] 2. The rotating assembly includes a first circular plate, a second circular plate, and a third circular plate. The first circular plate is fixedly connected to the first slider. A fixing nut is provided on the first circular plate. The rotating assembly is used to adjust the angle between the chuck and the horizontal plane. Loosening the fixing nut and rotating the second circular plate will drive the third circular plate to rotate, thereby adjusting the angle between the chuck and the horizontal plane. Tightening the fixing nut will fix the first and second circular plates together, and the second and third circular plates together. The first drive mechanism matches the chuck and can freely select different adaptation angles to adapt to blood samples of different concentrations. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In specific embodiment 1, such as Figures 1-5As shown, this utility model discloses a low-cost, simple pusher for sheet feeding, comprising a horizontally arranged base plate 1, a cover plate 2 on the base plate 1, an X-axis linear module 3 fixedly mounted on the base plate 1, and a Z-axis linear module 4 located on one side of the X-axis linear module 3 on the base plate 1. The Z-axis linear module 4 includes a vertically arranged upright rod 41, a first slider 42 slidably connected to the upright rod 41, a first drive mechanism 43 at the upper end of the upright rod 41, and the output shaft of the upright rod 41 connected to the first drive mechanism 43. The first drive mechanism 43 is used to drive the first slider 42 to slide vertically. The X-axis linear module 3 includes a horizontally arranged crossbar 31, a second slider 32 slidably connected to the crossbar 31, a second drive mechanism 33 at one end of the crossbar 31, and the output shaft of the crossbar 31 connected to the second drive mechanism 33. A placement plate 5 is slidably engaged with the second slider 32, and the second drive mechanism 33 is used to drive the second slider 32 to slide horizontally, for precise and controllable sheet feeding action.

[0032] like Figure 4 As shown, the X-axis linear module 3 is provided with a placement plate 5, which has a groove 13 for placing a glass slide. The placement plate 5 is slidably engaged with the X-axis linear module 3. The Z-axis linear module 4 is provided with a rotating assembly 6, which is slidably engaged with the Z-axis linear module 4. The rotating assembly 6 includes a first circular plate 61, a second circular plate 62, and a third circular plate 63. The first circular plate 61 is fixedly connected to the first slider 42, and a fixing nut 64 is provided on the first circular plate 61. Loosening the fixing nut 64 allows the nut to be detached from the slider. Nut 64, first circular plate 61 and second circular plate 62 are rotatably engaged. Tightening the fixing nut 64 fixes the first circular plate 61 and second circular plate 62 in a fixed manner; second circular plate 62 and third circular plate 63 are fixedly engaged. Loosening the fixing nut 64 allows the second circular plate 62 to rotate, thereby driving the third circular plate 63 to rotate, which is used to adjust the angle between the clamp 7 and the horizontal plane. The first drive mechanism 43 is matched with the clamp 7 and can freely select different adaptation angles to adapt to blood samples of different concentrations.

[0033] like Figure 4 , 5 As shown, a chuck 7 is hinged to the rotating assembly 6. A slot for mounting a scraper 8 is provided at one end of the chuck 7 near the placement plate 5. During vertical movement of the rotating assembly 6, the lower end of the scraper 8 contacts the glass slide. The glass slide is placed on the placement plate 5, and the scraper 8 is installed into the slot of the chuck 7. A small amount of anticoagulant blood is dripped onto a designated position on the glass slide. The Z-axis linear module 4 is driven to press the chuck 7 down. After the scraper 8 is pressed onto the glass slide, the X-axis linear module 3 is driven to pull the glass slide back slowly and then push it forward quickly. After this process is completed, the Z-axis linear module 4 is driven to move the chuck 7 back to its initial position, and the glass slide can be removed. The slides obtained by this slide pusher have stable quality, and the slide pusher has a simple structure and high working efficiency, which helps to significantly reduce costs.

[0034] In a specific embodiment 2, such as Figure 4 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, a first rotating shaft 9 is arranged horizontally on the third circular plate 63, and a second rotating shaft 10 is arranged at the end of the chuck 7 away from the scraper. A spring 11 is connected between the first rotating shaft 9 and the second rotating shaft 10, and the hinge is achieved through the spring 11, thereby realizing the flexible connection between the rotating component 6 and the chuck 7.

[0035] In a specific embodiment 3, such as Figure 1 As shown, the difference between this embodiment and embodiments 1 and 2 is that, in this embodiment, a spring piece 12 is provided near the edge of the end of the clamp 7 close to the placement plate 5, which is used to ensure that the scraper 8 is not easy to fall off and that the scraper 8 can be easily replaced.

[0036] In specific embodiment 4, the difference between this embodiment and embodiments 1, 2, and 3 is that the first drive mechanism 43 and the second drive mechanism 33 in this embodiment can be a servo motor, a cylinder, or any drive mechanism in the prior art.

[0037] During operation, first loosen the fixing nut 64, rotate the second circular plate 62, pre-adjust the angle between the clamp 7 and the horizontal plane. After adjusting to the appropriate angle, tighten the fixing nut 64 to fix the position of the clamp 7. Place the slide in the groove 13 of the placement plate 5, install the scraper 8 into the gap of the clamp 7, and drop a small amount of anticoagulant blood onto the designated position on the slide. Activate the first drive mechanism 43 to drive the first slider 42 to move vertically downward, thereby causing the clamp 7 to press down until the scraper 8 abuts against the slide. Activate the second drive mechanism 33 to drive the second slider 32 to move horizontally, thereby causing the slide to be pulled back slowly and then pushed forward quickly. After the operation is completed, the first drive mechanism 43 moves the clamp 7 to the initial position, remove the slide, and the smear is complete.

[0038] The angle between the chuck 7 and the horizontal plane is generally adjusted to 30-45°. During normal use, there is no need to adjust the angle between the chuck 7 and the horizontal plane. Simply adjust the vertical downward movement of the Z-axis linear module 4 to complete the coating.

[0039] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components, and can be direct connections or indirect connections through an intermediate medium. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0040] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
