Description

Technical Field

[0001] The invention relates to the technical field of smear staining, in particular to a microbial smear staining device. Background Art

[0002] Microorganisms are a general term for a type of organism, including bacteria, viruses, fungi, etc., covering many types of beneficial and harmful organisms. They are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, and sports, and are closely related to humans. In the daily inspections of the hospital laboratory, for the inspection of microorganisms in specimens such as blood, since microorganisms are nearly colorless and difficult to distinguish from the background, it is difficult to observe the microorganisms. It is necessary to use a glass slide coating and then staining treatment, and then do microscopic examination. Usually, Gram staining and Wright staining are used, and staining devices are often used in the slide staining process.

[0003] For example, the Chinese utility model patent with publication number CN220437939U discloses a microbial smear staining device, which can support and install the microbial smear with the help of a rotatable supporting mechanism, and the supporting mechanism is composed of a mounting rod, a supporting mechanism, a mounting shaft, a fixing rod, and a limiting rod. The microbial smear can be placed obliquely, which is conducive to staining through a dropper and rinsing with a storage bucket and a faucet, thereby improving the staining efficiency. However, in actual use, only a single number of smears can be stained, and it will be difficult to complete the staining of a large number of slides. It has certain limitations, and the function is relatively single, which is inconvenient to use. Summary of the invention

[0043] In the daily inspection of the hospital laboratory, for the inspection of microorganisms in specimens such as blood, since the microorganisms are almost colorless and difficult to distinguish from the background, it is difficult to observe the microorganisms. It is necessary to use a glass slide coating and then staining treatment, and then do a microscopic examination. Usually, Gram staining and Wright staining are used, and staining devices are often used in the slide staining process.

[0044] In the related art, the microbial smear can be supported and installed with the help of a rotatable supporting mechanism, and the supporting mechanism is composed of a mounting rod, a supporting mechanism, a mounting shaft, a fixing rod, and a limiting rod. The microbial smear can be placed obliquely, which is conducive to staining through a dropper and rinsing with a storage bucket and a faucet, thereby improving the staining efficiency. However, in actual use, only a single number of smears can be stained, and it will be difficult to complete the staining of large quantities of slides. It has certain limitations, and the function is relatively single, which is inconvenient to use.

[0045] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a microbial smear staining device. When in use, the structure pre-installed on the slider 21 and a specified number of sliders 21 are installed on the slide rail 20, and multiple smears are installed on multiple groups of clamping mechanisms 24. Then the staining operation can be performed, which is more convenient and quick, and improves the convenience of the device.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] Combination Figure 1-Figure 5The embodiment of the present application provides a microbial smear staining device, including: a staining table 10, a water tank 11 is fixedly connected to the top of the staining table 10, a tube body 12 is arranged on one side of the water tank 11, an extension tube 13 is arranged at one end of the tube body 12, a drain pipe 14 is arranged at the bottom of the staining table 10, and valves are arranged on the tube body 12 and the drain pipe 14, a slide rail 20 is fixedly connected to the staining table 10, a slider 21 is slidably connected to the slide rail 20, a plate body 22 is fixedly connected to one side of the slider 21, a plate body 6 23 is slidably connected in the plate body 1 22, a clamping mechanism 24 is arranged at one end of the plate body 6 23, the clamping mechanism 24 is used to fix the smear, a plate body 25 is arranged on one side of the clamping mechanism 24, a plate body 3 26 is slidably connected in the plate body 1 22, and the plate The body three 26 is rotatably connected with the plate body six 23, and a spring 27 is provided in the plate body one 22, and the two ends of the spring 27 are respectively fixedly connected with the plate body three 26 and the plate body one 22, and a threaded rod 31 is rotatably connected to the slider 21, and a cavity 30 is opened in the slider 21, and a push plate 32 is slidably connected in the cavity 30, and the threaded rod 31 is threadedly connected with the push plate 32, and the push plate 32 is tightly attached to the slide rail 20, and a rod body 40 is rotatably connected in the plate body one 22, and a bevel gear 41 is fixedly connected to one end of the rod body 40 and the outer side of the threaded rod 31, and the two bevel gears 41 are meshed, and a push block 42 is threadedly connected to the outer side of the rod body 40, and a limiting rod 43 is fixedly connected in the plate body one 22, and the limiting rod 43 passes through the push block 42.

[0048] The slider 21 and the structure above it are installed in advance and placed in a designated storage box. When the smear needs to be stained, a designated number of sliders 21 are taken out and cleaned and disinfected first. After the multiple sliders 21 are docked with the slide rail 20, the sliders 21 are pushed to slide on the slide rail 20. After the multiple sliders 21 are arranged regularly, the smears that need to be stained are fixed in turn through multiple groups of clamping mechanisms 24, and crystal violet dye is dripped and stained for 1-2 minutes. Then, the extension tube 13 is bent and one end of the extension tube 13 is placed directly above the smear. The valve on the tube body 12 is opened to allow the liquid in the water tank 11 to flow out and drip onto the smear. At this time, the clamping mechanism 24 is pulled outward to clamp the smear. The mechanism 24 drives the plate body 6 23 and the plate body 3 26 to slide outward, and at the same time pulls the spring 1 27 until one end of the plate body 6 23 slides out from the plate body 1 22, and then rotates the clamping mechanism 24, so that the plate body 6 23 rotates 20 degrees on the plate body 3 26, so that the clamping mechanism 24 is in an inclined state, and then the water dripping from one end of the extension tube 13 continues to fall on the smear, and after the smear is washed with water, iodine solution is dripped on the smear, and after staining for 1-2 minutes, the above-mentioned washing steps are repeated, and subsequent washing, decolorization, washing, re-staining and final washing are carried out in sequence, and after the smear is dried, the smear is removed and microscopic examination is performed. The Gram staining step and microscopic examination belong to the prior art, so they are not described in detail;

[0049] When the position of the slider 21 needs to be fixed, the threaded rod 31 is rotated, and the push plate 32 is threadedly connected with the threaded rod 31, so that the push plate 32 slides in the cavity 30 until the push plate 32 contacts the slide rail 20, which limits the left and right positions of the slider 21 (reference direction). Figure 1 ), thereby limiting the clamping mechanism 24 and the smear, making it convenient to drop the liquid on the smear;

[0050] When the threaded rod 31 is rotated, the threaded rod 31 drives the rod body 40 to rotate through the bevel gear 41, and then the rod body 40 is connected with the push block 42 through the thread, and the limit rod 43 limits the push block 42, so that the push block 42 can only slide left and right (direction reference Figure 2 ), so that the push block 42 pushes the plate body three 26 and the plate body six 23 to slide from the plate body one 22 to the outside, and when the limit on the position of the slider 21 is cancelled, the push block 42 pushes the plate body three 26 and the plate body six 23 to slide out from the plate body one 22, so that when the smear on the clamping mechanism 24 is washed with water, the clamping mechanism 24 is pushed horizontally to facilitate the discharge of residual water on the smear. Conversely, when the position of the slider 21 is limited, the plate body six 23 and the plate body three 26 slide into the plate body one 22 to prevent the position of the clamping mechanism 24 from shifting, which is convenient for the drip dyeing operation.

[0051] Specifically, the extension tube 13 is a stainless steel hose, has plasticity, and belongs to the prior art, so it will not be described in detail.

[0052] In some embodiments, a rubber pad is provided at the bottom of the push plate 32. When the rubber pad on the push plate 32 contacts the slide rail 20, the rubber pad is deformed to increase the friction with the slide rail 20 and improve the limiting effect.

[0053] In some embodiments, the clamping mechanism 24 includes: a plate body four 241 fixedly connected to one end of the plate body six 23; a slide groove 242 is opened in the plate body four 241; the plate body five 243 is slidably connected in the slide groove 242; a spring two 244 is arranged in the slide groove 242, and the two ends of the spring two 244 are respectively fixedly connected to the plate body four 241 and the plate body five 243.

[0054] When the smear needs to be clamped, the plate body 5 243 is pulled outward to slide the plate body 5 243 out of the slide groove 242, and the spring 244 is pulled. Then, the smear is placed between the two plate bodies 5 243, and the plate body 5 243 is clamped by the rebound force of the spring 244.

[0055] In some embodiments, a guide plate 50 is fixedly connected to the dyeing table 10. During washing, the liquid flows along the guide plate 50 to the drain pipe 14 to prevent the liquid from accumulating at the bottom of the dyeing table 10 and causing water splashing after washing again, thereby affecting normal dyeing.

[0056] In some embodiments, the cross-section of the slide rail 20 is T-shaped to prevent the slider 21 from detaching from the slide rail 20 .

[0057] In some embodiments, a limiting groove 60 is provided on the top of the dyeing table 10, and a plate body 61 is slidably connected in the limiting groove 60, a shell 62 is provided at one end of the plate body 61, an air inlet pipe 63 is fixedly connected to the top of the shell 62, a fan is provided in the air inlet pipe 63, a mounting block 64 is slidably connected to the bottom of the shell 62, an air outlet pipe 66 is fixedly connected to the bottom of the mounting block 64, an accordion cover 65 is provided between the side of the mounting block 64 and the shell 62, and the accordion cover 65 is also provided between two adjacent mounting blocks 64, and the interior of the air inlet pipe 63 and the air outlet pipe 66 are communicated with the interior of the shell 62.

[0058] When washing is completed or drying is required, the fan in the air inlet pipe 63 is turned on to suck external air into the shell 62, and then the valve on the corresponding position of the air outlet pipe 66 is opened, and then the air in the shell 62 is discharged from the designated air outlet pipe 66 and blown onto the corresponding smear to achieve air drying operation and improve work efficiency. The mounting block 64 can be directly pushed to drive the air outlet pipe 66 to slide in the shell 62 to adjust the position of the air outlet pipe 66. During the adjustment, the accordion cover 65 automatically extends or contracts to facilitate the discharge of air from the air outlet pipe 66.

[0059] In some embodiments, the plate body 61 is a telescopic plate to facilitate adjustment of the position of the shell 62.

[0060] In some embodiments, the plate body 7 61 is tilted so that when the air outlet pipe 66 discharges air, it does not affect the normal staining operation of other smears.

[0061] In some embodiments, a telescopic rod 70 is fixedly connected to the mounting block 64 , and a hole 71 is opened on the top of the plate body 22 .

[0062] When the air outlet pipe 66 is used, the telescopic rod 70 is pulled to insert one end of the telescopic rod 70 into the hole 71, so that the relative position between the smear and the mounting block 64 is fixed, so that the air discharged from the air outlet pipe 66 can directly act on the smear, thereby improving efficiency.

[0063] In some embodiments, the distance from one end of the slide rail 20 to the inner side of the dyeing table 10 is greater than the length of the clamping mechanism 24 , so as to facilitate the installation and disassembly of the slide block 21 .

[0064] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0065] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
