Description

Technical Field

[0001] This utility model specifically relates to a medical examination smear device, belonging to the field of medical device technology. Background Technology

[0002] In the field of medical testing, smears are an important sample processing method. They involve spreading blood, body fluids, secretions, and other test samples evenly on the surface of a glass slide, followed by fixation, staining, and other subsequent processing. Then, the samples are observed under a microscope to identify cell morphology, pathogen characteristics, and other features, providing a basis for disease diagnosis.

[0003] The operation of medical smears must follow a strict procedure. First, a clean glass slide is selected and labeled. Then, a quantitative sample to be tested is drawn up with a sampling tool and dropped onto a specific area of ​​the glass slide. Next, a pusher is used to push the sample smoothly from the point where it was dropped onto the other end of the glass slide at an appropriate angle and speed, so that the sample forms a uniform thin layer on the surface of the glass slide.

[0004] Currently, most smear operations in clinical practice rely on manual labor. This method is highly dependent on the operator's experience and skills. Even slight differences in the angle, force, and speed of pushing the slide can lead to uneven smear thickness and disordered cell distribution. Although some existing automated smear equipment can drive the slide to move automatically, the slide sizes vary depending on the test requirements. Most equipment lacks adjustment and fixation for slides of different sizes, which can easily cause the slide to shift during the push-slide movement, resulting in smear failure and making it difficult to meet the diverse test requirements in clinical practice. Therefore, this application provides a medical test smear device. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-5As shown, a medical smear device includes a base 1, a placement groove 2 on the top surface of the base 1, a glass slide can be placed in the placement groove 2, a fixing mechanism for fixing different types of glass slides is installed in the placement groove 2, fixing blocks 4 are symmetrically fixedly connected to the top surface of the placement groove 2, adjusting columns 5 are slidably connected in both fixing blocks 4, connecting columns 6 are slidably connected to the top of the two adjusting columns 5, connecting shafts 7 are rotatably connected to the opposite surfaces of the two connecting columns 6, a push plate clamp 8 is fixedly connected to the outer wall of the connecting shaft 7, a push plate can be fixedly clamped in the push plate clamp 8 by bolts, a moving mechanism for uniform smearing is installed in the fixing blocks 4, a controller 23 is fixedly connected to one side of the base 1, and all electrical components are electrically connected to the controller 23; The fixing mechanism includes clamping plates 11 that are symmetrically slidably connected inside the placement slot 2. Electric push rods 12 are fixedly connected to both sides of the base 1. The output ends of the two electric push rods 12 are fixedly connected to one side of the corresponding clamping plate 11. Guide rods 13 are symmetrically fixedly connected to one side of the two clamping plates 11. Multiple guide rods 13 are slidably connected to the base 1. Protective pads 14 are fixedly connected to the side of the two clamping plates 11 away from the guide rods 13. Secondly, an electric push rod 22 is fixedly connected inside one of the adjusting columns 5. The output end of the electric push rod 22 is fixedly connected to the bottom end of one of the connecting columns 6. A motor 9 is fixedly connected to one side of one of the connecting columns 6. The output end of the motor 9 is fixedly connected to one end of the connecting shaft 7.

[0019] In use, the slide is first placed inside the placement slot 2. Then, the controller 23 can be used to start the two electric push rods 12. At this time, the two electric push rods 12 will push the two clamping plates 11 to slide symmetrically inside the placement slot 2 until the inner walls of the two clamping plates 11 are in complete contact with the sides of the slide, thereby clamping and fixing the slide. At the same time, multiple guide rods 13 will also slide along with the movement of the clamping plates 11, thereby guiding the movement of the clamping plates 11 and keeping it stable. Meanwhile, the protective pads 14 provided on one side of the two clamping plates 11 can increase the friction between the clamping plates 11 and the slide, making the slide more securely fixed and preventing the slide from shifting during the smearing process. By clamping the slide with the clamping plates 11 on both sides, the device can be adapted to slides of different sizes to meet the diverse clinical testing needs. After the slide is fixed, the pusher is secured inside the pusher clamp 8 with bolts. The tilt angle of the pusher can then be input via controller 23. This signal is transmitted to motor 9, which rotates precisely according to the preset angle, thereby rotating the connecting shaft 7, pusher clamp 8, and pusher to the appropriate angle for the smear. Once the pusher angle is adjusted, electric push rod 22 is activated to gradually lower the two connecting columns 6 and the pusher, bringing the pusher into contact with the slide surface. Then, the liquid to be tested, such as 1-2 drops of blood, is dripped onto the center of one end of the slide using an external dropper. The moving mechanism is then activated to move the pusher towards... When the liquid approaches and comes into contact with the slide, the moving mechanism reverses, causing the pusher to move quickly and smoothly in the opposite direction to the liquid being tested. This movement of the pusher pulls and spreads the liquid evenly onto the surface of the glass slide, forming a uniform thin layer. This facilitates subsequent fixation, staining, and microscopic observation, thus achieving automated slide preparation. This avoids uneven preparation caused by differences in experience and skill during manual operation, improving the quality of the preparation and the accuracy of the test. After preparation, the fixation of the glass slide and the clamping of the pusher are quickly released. If any liquid drips or sticks inside the device, it is wiped clean and disinfected in time to avoid affecting subsequent use and causing cross-contamination.

[0020] Reference Figure 1 , Figure 2 and Figure 3 Multiple vacuum suction cups 15 are symmetrically and fixedly connected to the bottom surface of the placement slot 2. The multiple vacuum suction cups 15 are distributed on both sides of the through hole 3. The bottom ends of the multiple vacuum suction cups 15 on both sides of the through hole 3 are fixedly connected to the connecting air pipes 16. Vacuum pumps 17 are symmetrically and fixedly connected to the bottom surface of the base 1. The output ends of the two vacuum pumps 17 are fixedly connected to the two connecting air pipes 16 respectively.

[0021] In use, after the slide is placed inside the placement groove 2 and clamped by the two clamps 11, the bottom surface of the slide will be in contact with multiple vacuum suction cups 15. Therefore, the two vacuum pumps 17 can be started. At this time, the two vacuum pumps 17 will evacuate the air inside the multiple vacuum suction cups 15 through the two connecting air pipes 16, so that the multiple vacuum suction cups 15 form a negative pressure. This allows the multiple vacuum suction cups 15 to adsorb and fix the bottom surface of the slide, thereby increasing the stability of the slide placement and preventing the slide from shifting axially during the slide preparation process. At the same time, the multiple vacuum suction cups 15 are evenly distributed on the bottom surface inside the placement groove 2, which can effectively increase the contact area with the bottom surface of the slide and improve the adsorption and fixation effect.

[0022] Reference Figure 1 and Figure 4The moving mechanism includes a second motor 19 fixedly connected to one end of one of the fixed blocks 4. A lead screw 18 is fixedly connected to the output end of the second motor 19. The lead screw 18 is located inside the fixed block 4. Slider 20 is fixedly connected to the bottom end of each of the two adjusting columns 5. The slider 20 at the bottom end of one of the adjusting columns 5 is threadedly connected to the outer wall of the lead screw 18. A sliding rod 21 is fixedly connected inside the fixed block 4 opposite to the lead screw 18. The slider 20 opposite to the lead screw 18 is slidably connected to the outer wall of the sliding rod 21.

[0023] In use, the motor 19 can be started to drive the lead screw 18 to rotate. Since one of the sliders 20 is threadedly connected to the outer wall of the lead screw 18, the rotation of the lead screw 18 will drive one slider 20 and the top adjusting column 5 to move together. The other slider 20 will slide together on the outer wall of the slide rod 21 according to the pull of the connecting shaft 7 and the push plate clamp 8. At the same time, it plays a guiding and stabilizing role in the movement of the two adjusting columns 5, ensuring that the two adjusting columns 5 can move smoothly and simultaneously in a straight line along the inside of the fixed block 4, thereby driving the push plate to move and realizing the operation of uniform coating.

[0024] Reference Figure 1 and Figure 4 A camera 10 is fixedly connected to one side of the push plate clamp 8, and the camera 10 is electrically connected to the controller 23.

[0025] During use, as soon as the smear is completed, the camera 10 immediately captures an image of the smear and transmits the information to the controller 23. The controller 23 then uses internal program algorithms and AI recognition to quickly analyze the thickness uniformity and cell distribution density of the smear and provides real-time feedback on whether the smear is qualified. This allows for a rapid quality assessment after the smear operation is completed, avoiding misjudgments caused by the subjectivity of human judgment and differences in experience, and further improving inspection efficiency and accuracy.

[0026] As a technical optimization of this utility model: First, the glass slide is placed inside the placement groove 2. Then, the controller 23 can be used to start the operation of two electric push rods 12. At this time, the two electric push rods 12 will push the two clamping plates 11 to slide symmetrically inside the placement groove 2 until the inner walls of the two clamping plates 11 are completely in contact with the sides of the glass slide, thereby clamping and fixing the glass slide. At the same time, multiple guide rods 13 will also slide along with the movement of the clamping plates 11, thereby guiding the movement of the clamping plates 11 and keeping them stable. Meanwhile, protective pads 14 are provided on one side of each of the two clamping plates 11, which can increase the friction between the clamping plates 11 and the glass slide, making the glass slide more securely fixed and preventing the glass slide from shifting during the coating process. By clamping the glass slide with the clamping plates 11 on both sides, the glass slide can be mounted securely. The device can accommodate slides of different sizes to meet diverse clinical testing needs. After the slide is placed inside the placement slot 2 and held by two clamps 11, the bottom surface of the slide will be in contact with multiple vacuum suction cups 15. Therefore, two vacuum pumps 17 can be started. At this time, the two vacuum pumps 17 will evacuate the air inside the multiple vacuum suction cups 15 through two connecting air tubes 16, so that a negative pressure is formed inside the multiple vacuum suction cups 15. This allows the multiple vacuum suction cups 15 to adsorb and fix the bottom surface of the slide, thereby increasing the stability of the slide placement and preventing the slide from shifting axially during the slide preparation process. At the same time, the multiple vacuum suction cups 15 are evenly distributed on the bottom surface inside the placement slot 2, which can effectively increase the contact area with the bottom surface of the slide and improve the adsorption and fixation effect. After the slide is fixed, the pusher is secured inside the pusher clamp 8 with bolts. The tilt angle of the pusher can then be input via controller 23. This signal is transmitted to motor 9, which rotates precisely according to the preset angle, driving the connecting shaft 7, pusher clamp 8, and pusher to the appropriate angle for the smear. Once the pusher angle is adjusted, electric push rod 22 is activated to lower the two connecting posts 6 and the pusher, bringing the pusher into contact with the slide surface. Then, the liquid to be tested, such as 1-2 drops of blood, is dripped onto the center of one end of the slide using an external dropper. Motor 29 is then activated to rotate the lead screw 18. Since one slider 20 is threaded to the outer wall of the lead screw 18, rotation of the lead screw 18 will move one slider 20 and the top adjusting post 5 together. The other slider 20 will move according to the pull of the connecting shaft 7 and pusher clamp 8, moving along the slide rod 2. The outer wall slides together, guiding and stabilizing the movement of the two adjusting columns 5. This allows the adjusting columns 5 to approach and contact the liquid. After the push plate contacts the liquid, the droplets turn into strips and collect on the contact end between the push plate and the slide. At this point, the motor 19 can be reversed immediately to drive the push plate to move quickly and smoothly in the opposite direction to the liquid being tested. By pulling the push plate, the liquid being tested is moved and evenly coated on the surface of the slide, forming a uniform thin layer. This facilitates subsequent fixation, staining, and microscopic observation, thus achieving automatic slide preparation and avoiding uneven preparation caused by differences in experience and skills during manual operation. This improves the quality of the slide preparation and the accuracy of the inspection. After the preparation is completed, the fixation of the slide and the clamping of the push plate are quickly released. If any liquid drips or sticks inside the device, it is wiped and disinfected in time to avoid affecting subsequent use and causing cross-contamination.
