Description

Technical Field

[0001] This utility model belongs to the field of medical tool technology, specifically relating to an angle-fixing push plate for blood smear preparation. Background Technology

[0002] Blood smears are a fundamental procedure in clinical laboratory testing for observing blood cell morphology. Their quality directly affects the uniformity of cell distribution, clarity of morphology, and diagnostic accuracy under a microscope. Traditional blood smear preparation relies on manual operation. The specific steps are as follows: a drop of blood is placed on one end of a glass slide, and another slide is used to push it forward at a certain angle (theoretically optimal angle is 25°-30°) at a uniform speed to spread the blood evenly into a thin layer.

[0003] Traditional manual slide preparation has the following significant drawbacks: angle control relies on experience, requiring precise control of the slide angle, but different operators have vastly different techniques (e.g., beginners often cause the angle to be too large or too small due to nervousness), and even the same operator is prone to angle deviations due to hand tremors when performing repeated operations; the quality of the smear is unstable, as angle deviation directly affects the smear thickness. An excessively large angle results in an overly thick smear (cell overlap, making it difficult to observe individual cells), while an excessively small angle results in an overly thin smear (sparse cell distribution, requiring repeated searching of the field of view); the operation is inefficient, as unqualified smears need to be re-prepared, wasting samples, reagents, and time (a single smear takes about 2 minutes, and repeated operations can increase time costs by more than 30%); training costs are high, as new employees need extensive practice (usually 1-2 weeks) to master a stable angle, hindering the efficiency of departmental manpower allocation. Therefore, there is an urgent need for a simple, low-cost auxiliary tool to solve the problem of the difficulty in standardizing the slide angle. This necessitates the development of an angle-fixing slide preparation plate for blood smear preparation to address the aforementioned issues. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an angle-fixing slide pusher for blood smear preparation, which features simple structure, low cost, and good smear effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-fixed slide pusher for blood smear preparation, comprising a U-shaped operating frame, with symmetrically arranged sliding grooves on both inner walls of the U-shaped operating frame, a slot on the bottom surface of the inner wall of the U-shaped operating frame, a support plate inserted into the inner side of the sliding groove, an inclined flat cylinder inserted into one side of the support plate, a scraper penetrating the inner side of the inclined flat cylinder, a glass slide being engaged with the inner side of the slot, the lower end of the scraper being located on one side of the glass slide, and clamping components symmetrically fixed to the sidewall of the inclined flat cylinder, the clamping components comprising a connecting plate, a first elastic plate, and a second elastic plate, one end of the connecting plate being fixedly connected to the first elastic plate, one end of the first elastic plate being fixedly connected to the inclined flat cylinder, the other end of the connecting plate being fixedly connected to the second elastic plate, one end of the second elastic plate being fixedly connected to the inclined flat cylinder, and a compression pad fixed to the sidewall of the first elastic plate, the compression pad being attached to the sidewall of the glass slide.

[0006] As a preferred technical solution of the angle-fixing slide pusher for blood smear preparation according to this utility model, the support plate has a slot on one side wall, and the inclined flat cylinder has rectangular plates symmetrically arranged on its side wall, with the rectangular plates inserted into the inside of the slot.

[0007] As a preferred technical solution of the angle-fixing slide pusher for blood smear preparation according to this utility model, a sliding plate is fixed to the other side wall of the support plate. The sliding plate is inserted into the inner side of the slide groove, and one end of the slide groove passes through the side wall of the U-shaped operating frame.

[0008] As a preferred technical solution of the angle-fixed slide pusher for blood smear preparation according to this utility model, two support plates are symmetrically arranged, the width of the slide plate is adapted to the width of the slide groove, and the size of the rectangular plate is adapted to the inner size of the slot.

[0009] As a preferred technical solution for the angle-fixing pusher plate for blood smear preparation according to this utility model, L-shaped silicone pads are symmetrically fixed on the bottom edge of the U-shaped operation frame.

[0010] As a preferred technical solution for an angle-fixed slide pusher for blood smear preparation according to this utility model, one end of the L-shaped silicone pad is fixedly connected to the bottom of the U-shaped operating frame, and the other end of the L-shaped silicone pad is fixedly connected to the side wall of the U-shaped operating frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, this utility model employs a U-shaped operating frame, a support plate, an inclined flat cylinder, a glass slide, and a scraper. The support plate is symmetrically engaged on the inner walls of both sides of the U-shaped operating frame, allowing it to slide inside the frame. The inclined flat cylinder is then inserted into the side walls of the support plate via rectangular plates on both sides, supporting it within the operating frame. The inclined angle of the flat cylinder is fixed at 30 degrees. The operator engages the glass slide inside the operating frame, drips blood onto the top right side of the slide, inserts the scraper into the flat cylinder, and moves the cylinder to bring the scraper into contact with the blood. The operator then pushes the cylinder at a constant speed to spread the blood evenly. The fixed scraper angle eliminates human error, improves the pass rate of smear preparation, reduces reliance on experience, and allows novices to master standard operations with short training, shortening the training cycle. Furthermore, the single-smear success rate is high, reducing the need for duplicate slides. In addition, the overall tool structure is simple, has low operating costs, is easily promoted to primary hospitals, and is highly practical.

[0013] In addition, operators can slide the support plate inside the groove until the support plate is moved out of the U-shaped operating frame. At the same time, the inclined flat cylinder can be easily pulled out from the side wall of the support plate. The whole tool is easy to disassemble. When operators need to change the inclined flat cylinder with different inclination angles, 25-degree and 30-degree scrapers can be prepared in advance for flexible use. The easy-to-disassemble tool is convenient for subsequent cleaning and disinfection. Attached Figure Description

[0021] 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. Example 1

[0022] Please see Figures 1-5 This utility model provides the following technical solution: an angle-fixing slide pusher for blood smear preparation, comprising a U-shaped operating frame 1, with symmetrical sliding grooves 12 on both inner walls of the U-shaped operating frame 1, and a slot 13 on the bottom surface of the inner wall of the U-shaped operating frame 1. A support plate 2 is inserted into the inner side of the sliding groove 12. See attached drawing for details. Figure 1 and attached Figure 2 The support plate 2 can slide along the slide groove 12. An inclined flat cylinder 3 is inserted into one side of the support plate 2 at an inclination angle of 30 degrees. A scraper 4 passes through the inner side of the inclined flat cylinder 3, also at an inclination angle of 30 degrees. A glass slide 6 is engaged with the inner side of the slot 13. The lower end of the scraper 4 is located on one side of the glass slide 6. When preparing blood smears, the operator inserts the scraper 4 (i.e., another slide) into the inner side of the flat cylinder at an inclination angle of 30 degrees. Then, the operator moves the flat cylinder so that the lower end of the scraper 4 rests against the blood droplet on the top surface of the glass slide 6. The operator then moves the flat cylinder at a uniform speed to drive the scraper 4 to scrape the blood droplet evenly. The operation is simple and convenient. At the same time, the angle of the scraper 4 is fixed, and even novices can perform standard operations after a short training period, improving the success rate of smears and making it highly practical.

[0023] Reference Figure 2 , Figure 3 and Figure 5As shown, specifically, one side wall of the support plate 2 is provided with a slot 21, and the side wall of the inclined flat cylinder 3 is symmetrically provided with a rectangular plate 31. The rectangular plate 31 is inserted into the inside of the slot 21 for easy disassembly and assembly. The other side wall of the support plate 2 is fixed with a sliding plate 22, which is inserted into the inside of the slide groove 12. One end of the slide groove 12 passes through the side wall of the U-shaped operating frame 1, which also facilitates the removal and disassembly of the support plate 2. There are two symmetrical support plates 2. The width of the sliding plate 22 is adapted to the width of the slide groove 12, and the size of the rectangular plate 31 is adapted to the inner size of the slot 21. This solution, through the easily disassembled support plate 2 and inclined flat cylinder 3, not only facilitates subsequent cleaning, but also allows operators to prepare inclined flat cylinders 3 with different tilt angles in advance. Different tilt angle flat cylinders can be flexibly inserted and installed according to the needs of the coating, which is suitable for different scenario requirements.

[0024] Reference Figure 1 As shown, specifically, L-shaped silicone pads 11 are symmetrically fixed to the bottom edge of the U-shaped operating frame 1. One end of the L-shaped silicone pad 11 is fixedly connected to the bottom of the U-shaped operating frame 1, and the other end of the L-shaped silicone pad 11 is fixedly connected to the side wall of the U-shaped operating frame 1. The silicone pads can improve the friction between the U-shaped operating frame 1 and the external operating table, prevent the operating frame from moving easily when the scraper 4 is pushed, and improve the stability of operation. Example 2

[0025] In another embodiment of this solution, refer to Figure 2 and Figure 4 As shown, specifically, clamping components 5 are symmetrically fixed to the sidewalls of the inclined flat cylinder 3. The clamping components 5 include a connecting plate 51, a first elastic plate 52, and a second elastic plate 53. One end of the connecting plate 51 is fixedly connected to the first elastic plate 52, and one end of the first elastic plate 52 is fixedly connected to the inclined flat cylinder 3. The other end of the connecting plate 51 is fixedly connected to the second elastic plate 53, and one end of the second elastic plate 53 is fixedly connected to the inclined flat cylinder 3. The three plates form a triangle. A compression pad 521 is fixed to the sidewall of the first elastic plate 52. The squeezing pad 521 is attached to the side wall of the glass slide 6. Before inserting the scraper 4 into the inside of the flat cylinder, the operator presses one end of the connecting plates 51 on both sides, causing the first elastic plate 52 to unfold elastically to the outside, thereby causing the squeezing pads 521 on both sides to move outward. Then the operator inserts the scraper 4 into the inside of the flat cylinder until the lower end of the scraper 4 abuts against the glass slide 6. Then the connecting plates 51 are released, so that the squeezing pad 521 clamps and fixes the scraper 4, making the scraper 4 more stable when moving to spread the slide, and further improving the stability of the spread.

[0026] The working principle and usage process of this utility model are as follows: When preparing blood smears, the operator places the U-shaped operating frame 1 on the operating table, then snaps the glass slide 6 into the slot 13 on the operating frame. Next, the operator snaps the sliding plate 22 on the support plate 2 into the groove 12. The inclined flat cylinder 3 is then inserted into the support plate 2 via the rectangular plate 31, so that the inclined flat cylinder 3 is located inside the operating frame. The operator then moves the flat cylinder to the right side of the glass slide 6, and drips blood onto the top right end of the glass slide 6. The operator then inserts the scraper 4 into the inside of the flat cylinder, so that one end of the scraper 4 rests against the blood droplet on the top surface of the glass slide 6. The operator then slides the flat cylinder at a uniform speed, causing the scraper 4 to scrape the blood droplet evenly. The overall structure is simple and the operation is convenient.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
