Description

Technical Field

[0001] This utility model relates to the field of blood smears, and in particular to an automatic slide pushing device. Background Technology

[0002] When testing blood, a drop of blood is first placed on a glass slide. Another glass slide is then tilted and used to spread the blood evenly, forming a single-cell layer. This is allowed to air dry for a few minutes before the test reagent is applied. One glass slide is then placed on top of the other and moved horizontally to push the blood drop into a straight line, before being moved horizontally in the opposite direction to spread it evenly. Currently, manual slide spreading relies heavily on experience and requires training; otherwise, the cell layer formed by this pushing process will be uneven in thickness, failing to form a stable single-cell layer.

[0003] Chinese patent application date: November 9, 2023, publication number: CN221148240U, discloses a blood slide applicator. Its technical solution includes: a placement seat fixedly installed on the top of a seat, with a slot on the top of the placement seat; a slide rail fixedly installed on one side of the top of the seat, with a support frame slidably mounted on the top of the slide rail via a sliding block; a fixing rod fixedly installed on one side of the top of the support frame, with a locking hole on the top of the fixing rod, and a pressure plate fixedly installed inside the locking hole via a support spring; and a drying seat fixedly installed on the back of the seat. This invention, through the combination of various structures, allows for quick-release installation and removal of the load slide, facilitating the replacement of auxiliary slides according to the blood smear conditions, increasing the functionality of the device. Furthermore, this device can accelerate the drying process of the load slide after smearing, increasing the drying speed of the smear on the load slide and improving efficiency.

[0004] In this technical solution, although no experience is required to complete the slide pushing operation, the fixed height of the fixing rod makes it difficult to adjust the distance between the two slides. During the slide pushing process, the pressure on the two slides is easily too high or there is a gap between the two slides, resulting in poor slide pushing effect. Multiple operations are required to push the slides, which reduces the slide pushing efficiency. Utility Model Content

[0020] 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.

[0021] like Figures 1-5 As shown, an automatic slide pusher includes a stage 100, a support column 200 fixedly mounted on the top of the stage 100, a top plate 300 fixedly mounted on the top of the support column 200, and a clamping and limiting member 400 provided on the top of the stage 100 for clamping and limiting a slide containing blood. A reciprocating drive member 500 is provided at the bottom of the top plate 300, and a slide mounting base 600 is slidably connected to the output end of the reciprocating drive member 500 for mounting another slide. Transverse guide members 700 are provided on both the front and rear sides of the slide mounting base 600, and a height adjustment member 800 is provided between the transverse guide member 700 and the top plate 300. By adjusting the height of the transverse guide member 700 through the height adjustment member 800, the distance between the slide on the slide mounting base 600 and the slide inside the clamping and limiting member 400 is adjusted, allowing the two slides to fit together.

[0022] In use, the clamping and limiting component 400 includes a tray 401, and a receiving groove 402 is provided on the top of the platform 100. The tray 401 is slidably connected in the receiving groove 402. A U-shaped baffle 403 is fixedly installed on the top of the platform 100. A step plate 404 is provided at the top front end of the tray 401. The step plate 404 is slidably connected in the U-shaped baffle 403. A groove 405 is provided on the upper surface of the step plate 404. The groove 405 facilitates the nail to be caught on the step plate 404, thereby facilitating the sliding of the tray 401 in the receiving groove 402.

[0023] By placing a glass slide with a drop of blood on top of the support plate 401, pressing a finger against the groove 405 at the top of the stepped plate 404, and pushing the support plate 401 backward until the glass slide is against the rear end of the U-shaped retaining frame 403, the glass slide is clamped and fixed by the cooperation of the stepped plate 404 and the U-shaped retaining frame 403. Furthermore, the thickness of the rear end of the stepped plate 404 and the U-shaped retaining frame 403 is less than the thickness of the glass slide, preventing the glass slide on the slide mounting base 600 from being blocked by the stepped plate 404 or the U-shaped retaining frame 403 when the two glass slides are attached.

[0024] In practice, the reciprocating drive 500 includes a motor 501, which may be model HG-AK0236. A rotating shaft 502 is connected to the left output end of the motor 501. A rotating cylinder 503 is fixedly mounted on the rotating shaft 502. An annular groove 504 is formed on the surface of the rotating cylinder 503. A sleeve 505 is fitted around the outside of the rotating cylinder 503. A sliding ball 506 is fixedly mounted on the inner wall of the sleeve 505 and slidably connected within the annular groove 504. A vertical plate 507 is fixedly mounted at the bottom of the sleeve 505. The sleeve 505 and the vertical plate 507 serve as the output ends of the reciprocating drive 500. A slide mounting base 600 is slidably connected to the vertical plate 507.

[0025] The slide mount 600 is guided by the transverse guide 700 to prevent the slide mount 600, sleeve 505, and vertical plate 507 from rotating with the rotating drum 503. Thus, when the motor 501 drives the rotating shaft 502 and rotating drum 503 to rotate one revolution, the sliding ball 506 slides along the annular groove 504, causing the sleeve 505, vertical plate 507, and slide mount 600 to reciprocate once along the transverse guide 700. That is, the slide mount 600 first moves from left to right along the transverse guide 700, and then from right to left.

[0026] Specifically, the annular groove 504 includes a first inclined groove 5041 and a second inclined groove 5042 formed on the surface of the rotating cylinder 503. The distance between the first inclined groove 5041 and the second inclined groove 5042 gradually increases from left to right. The left ends of the first inclined groove 5041 and the second inclined groove 5042 are connected by a first arc-shaped groove 5043, and the right ends of the first inclined groove 5041 and the second inclined groove 5042 are connected by a second arc-shaped groove 5044. The arc centers of the first arc-shaped groove 5043 and the second arc-shaped groove 5044 are both coincident with the axis of the rotating cylinder 503.

[0027] During the rotation of the rotating drum 503, if the sliding ball 506 is located inside the first inclined groove 5041 or the second inclined groove 5042, the sliding ball 506 will be subjected to the squeezing force of the side wall of the first inclined groove 5041 or the second inclined groove 5042, causing the sleeve 505, the vertical plate 507 and the slide mounting base 600 to slide laterally along the transverse guide 700; if the sliding ball 506 is located inside the first arc groove 5043 or the second arc groove 5044, the sliding ball 506 will slide relative to the first arc groove 5043 or the second arc groove 5044, and the sleeve 505, the vertical plate 507 and the slide mounting base 600 will remain relatively stationary with respect to the transverse guide 700.

[0028] The slide mount 600 includes a slider 601 slidably connected to a vertical plate 507, with an annular groove 504 passing through the center of the slider 601. A tilting arm 602 is fixedly mounted at the lower left corner of the slider 601, with a tilt range of 30°-45°. A slot 603 is provided on the front side of the tilting arm 602, and a fastening screw 604 is threaded onto the top of the tilting arm 602. A slide can be inserted into the tilting arm 602 through the slot 603, and then the fastening screw 604 can be tightened to fix the slide inside the tilting arm 602.

[0029] In reality, each transverse guide 700 includes a mounting plate 701. The surface of the mounting plate 701 is provided with a first horizontal groove 702, a third inclined groove 703 and a second horizontal groove 704 running through it from right to left. The second horizontal groove 704 is higher than the first horizontal groove 702. The two ends of the third inclined groove 703 are respectively connected to the first horizontal groove 702 and the second horizontal groove 704. The slide mounting base 600 is fixedly installed with extension plates 705 on both the front and rear sides. The surface of the extension plate 705 is fixedly installed with sliding posts 706. The sliding posts 706 are slidably connected in the first horizontal groove 702, the third inclined groove 703 and the second horizontal groove 704.

[0030] The slide mount 600 is driven by the reciprocating drive 500 to move from left to right first, and then from right to left. When the slide mount 600 moves from left to right, the slide column 706 first slides along the second horizontal groove 704, with the bottom of the slide on the slide mount 600 positioned above another slide. When the slide column 706 slides along the third inclined groove 703, the slide on the slide mount 600 gradually moves closer to the other slide. When the slide column 706 slides along the first horizontal groove 702, the slide on the slide mount 600 slides against the top of the other slide. Moreover, when the slide column 706 slides to the right end of the first horizontal groove 702, the two slides remain in contact.

[0031] The height adjustment component 800 includes an arched plate 801, two mounting plates 701 fixedly mounted on the bottom of the arched plate 801, and two sliding rods 802 fixedly mounted on the top of the arched plate 801. The sliding rods 802 are slidably connected to the top plate 300. A threaded rod 803 is rotatably connected to the center of the top of the arched plate 801, and the threaded rod 803 is threadedly connected to the top plate 300. By turning the threaded rod 803, the sliding rods 802 slide relative to the top plate 300, thereby adjusting the height of the mounting plate 701.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
