Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, and in particular to a medical testing microbial smear staining device. Background Technology

[0002] During the medical testing process, microbial cells are colorless and transparent under a microscope, and there is no obvious color contrast with the background of the slide. Therefore, it is difficult to observe microbial cells with a regular optical microscope. To facilitate the observation of microbial cells under a regular microbial microscope, it is necessary to stain the microbial samples so that the morphology and structure of the microbial cells can be clearly observed. This process is called microbial smear staining. Microbial smear staining plays a very important role in the preliminary identification of pathogenic microorganisms. Commonly used staining methods include Gram staining, acid-fast staining, and weakly acid-fast staining.

[0003] A search revealed that Chinese patent number CN223259376U discloses a microbial smear staining device for medical testing, relating to the technical field of microbial smear staining devices. The device includes a base, a fixed frame fixedly connected to the upper end of the base, a nozzle slidably connected inside the fixed frame, a disassembly mechanism on the fixed frame, a turntable fixedly connected to the upper end of the output shaft of the base, a glass slide in contact with the upper end of the turntable, a baffle fixedly connected to the upper end of the turntable, and a fixed plate fixedly connected inside the turntable.

[0004] In order to improve work efficiency, the aforementioned public document uses a roundabout to install glass slides, so that multiple glass slides can be cyclically dyed. During this process, only the box needs to be manually placed and the glass slides removed. Although this can improve efficiency to a certain extent, it requires manually removing each dyed glass slide one by one before placing a new glass slide. This operation requires repeated operation of the limit frame, which is too cumbersome and cannot automate the removal of glass slides. It is very inconvenient to use.

[0005] To address the aforementioned issues, this application proposes a medical testing microbial smear staining device. Utility Model Content

[0028] Please see Figure 1-8 The technical solution provided by this utility model specifically includes the following embodiments:

[0029] A medical testing microbial smear staining device includes a mounting base 1, a fixed support 2 fixedly mounted on the top of the mounting base 1, a nozzle 3 fixedly mounted on the bottom of the fixed support 2, an alternating mechanism mounted below the nozzle 3, the alternating mechanism being located on the top of the mounting base 1 and extending into the interior of the mounting base 1, two symmetrically positioned lifting mechanisms fixedly mounted inside the mounting base 1, two storage boxes 13 arranged horizontally connected through the top of the mounting base 1, the storage boxes 13 extending into the lifting mechanisms, multiple vertically distributed trays 14 fixedly connected to both sides of the interior of the storage boxes 13, and two horizontally distributed pushing mechanisms fixedly mounted on the top of the mounting base 1, the pushing mechanisms being located in front of the alternating mechanism.

[0030] A liquid supply pipe 4 is fixedly connected to the rear side of the nozzle 3. The liquid supply pipe 4 passes through the fixed bracket 2 and extends to the rear of the fixed bracket 2. The liquid supply pipe 4 is used to supply the dyeing solution to the nozzle 3. The liquid supply pipe 4 is connected to the dyeing solution container. The nozzle 3 can be controlled by the controller 23 to drip the dyeing solution in a quantitative manner.

[0031] The alternation mechanism includes a base 5, which is slidably connected to the top of the mounting base 1. Two left-right distributed support frames 6 are fixedly connected to the top of the base 5. Each support frame 6 is composed of two left-right distributed T-shaped plates and is used to place glass slides. The top of the mounting base 1 has a first opening 10 located below the base 5. The alternation mechanism also includes a connecting block 7 that passes through the first opening 10. The top of the interior of the mounting base 1 is movably connected to a first threaded rod 8 through a bearing seat. The first threaded rod 8 passes through the connecting block 7 and the connecting block 7 and the first threaded rod 8 are threadedly connected. The top of the interior of the mounting base 1 is fixedly connected to a first motor 9. The output shaft of the first motor 9 and one end of the first threaded rod 8 are fixedly connected through a coupling.

[0032] Slides are placed on the support frame 6. When the base 5 moves left and right with the two support frames 6, the slide on one support frame 6 will always be below the nozzle 3, while the slide on the other support frame 6 will always be in front of one of the storage boxes 13. The slide below the nozzle 3 is used for staining operations, and the slide in front of the storage box 13 can be pushed into the storage box 13 by the pushing mechanism. Then, a new slide can be placed on the support frame 6. The left and right movement of the base 5 is driven by the first motor 9, the first threaded rod 8 and the connecting block 7. The first opening 10 guides the connecting block 7 while it moves, and can also position the maximum stroke of its left and right movement, so that it stops at the most suitable position each time it moves to the maximum distance.

[0033] The lifting mechanism includes a limiting sleeve 11, which is fixedly connected inside the mounting base 1, and the top of the limiting sleeve 11 is connected to the top of the mounting base 1. The storage box 13 is located above the mounting base 1 and extends into the limiting sleeve 11. A bracket 17 is connected through one side of the mounting base 1 and is located at the bottom of the storage box 13. A second opening 12 is opened on one side of the limiting sleeve 11, and the bracket 17 passes through the second opening 12. The lifting mechanism also includes a second threaded rod 16, which is movably connected inside the mounting base 1. The second threaded rod 16 is located on the side of the limiting sleeve 11 with the second opening 12, passes through the bracket 17, and is threadedly connected to the bracket 17. A second motor 18 is fixedly connected to the bottom of the mounting base 1. Both the output shaft of the second motor 18 and the outer end of the second threaded rod 16 are fixedly connected to bevel gears 19, which are located below the bracket 17 and mesh with each other.

[0034] When the storage box 13 is placed inside the limiting sleeve 11, it can maintain a vertical position and can only move up and down. Inside the limiting sleeve 11, the storage box 13 is supported by the bracket 17 and kept at a suitable height. After a glass slide is placed inside the storage box 13, the second motor 18, bevel gear 19, and second threaded rod 16 can drive the bracket 17 to move the storage box 13 down a certain distance, so that the upper support plate 14 inside the storage box 13 can be moved down to the appropriate position for the next glass slide to be pushed in and supported. When the bracket 17 is driven to move up and down, it is guided and limited by the second opening 12 to prevent the bracket 17 from rotating and affecting the support effect on the storage box 13.

[0035] The pushing mechanism includes an electric push rod 20, which is fixedly connected to the top of the mounting base 1. A push block 21 is fixedly connected to the end of the piston rod of the electric push rod 20. A protective cover 22 is fitted over the electric push rod 20 and is fixedly connected to the top of the mounting base 1.

[0036] When the stained slide moves to the front of the storage box 13, the electric push rod 20 in the corresponding pushing mechanism will automatically start, and then push the slide into the storage box 13 by pushing the push block 21. After the pushing is completed, the electric push rod 20 will return to its original position with the push block 21, at which time a new slide can be placed on the corresponding support frame 6.

[0037] The top of the mounting base 1 is fixedly equipped with a controller 23, which is located between the two pushing mechanisms. The controller 23 is electrically connected to the nozzle 3, the first motor 9, the second motor 18 and the electric push rod 20. The mounting base 1 can have a built-in power supply (not shown in the figure) to supply power to each electrical component. In addition to controlling each component, the controller 23 can also set the running program. The specific program steps are set by the actual operation requirements and will not be described in detail here.

[0038] The slides described above all contain microbial smear samples and are not simply slides.

[0039] Working principle:

[0040] In use, the operating logic of the alternation mechanism, lifting mechanism, and pushing mechanism can be set by the controller 23. Then, a slide is placed on the idle support frame 6 manually. When the alternation mechanism is running, the first motor 9 drives the first threaded rod 8 to rotate. Then, through the transmission between the connecting block 7 and the first threaded rod 8, the base 5 and the two support frames 6 above the base 5 can move back and forth left and right. When the left support frame 6 moves to the front of the corresponding storage box 13, the electric push rod 20 starts automatically and pushes the slide on the support frame 6 backward through the push block 21 and into the storage box 13. Then, the slide is supported by the corresponding tray 14 inside the storage box 13. After the slide is pushed, the electric push rod 20 retracts back to its original position. At this time, the support frame 6 is idle, and a slide can be placed on the support frame 6 for later use. During this period, the slide on the right support frame 6 is located directly below the nozzle 3. The nozzle 3 drips staining solution onto the microbial image on the slide for staining. The staining solution is applied to the slides on the left side of the support frame 6 by the spray nozzle 3, while the slides on the right side of the support frame 6 are pushed into the corresponding storage box 13 by the corresponding pushing mechanism. When a slide is inserted into the storage box 13, the second motor 18 will start automatically and drive the second threaded rod 16 to rotate through the meshing of two bevel gears 19. When the second threaded rod 16 rotates, it moves the bracket 17 down a certain distance. Since the storage box 13 is supported by the bracket 17 inside the limiting sleeve 11, the storage box 13 will move down synchronously when the bracket 17 moves down, until the idle tray 14 above moves down with the storage box 13 to the same height as the support frame 6. At this time, the storage box 13 can be used to insert more slides. The above steps are repeated until the storage box 13 is full of slides. Then, the storage box 13 full of slides can be lifted out and transferred for use by the handle 15.
