Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a rapid preparation device for multi-specification microbial smears. Background Technology
[0002] When medical staff perform pathological diagnosis, they generally need to collect samples to prepare specimens in order to determine the patient's pathological condition. Specimen collection generally involves liquid samples such as blood and solid samples such as tissue sections. At present, the preparation method is still relatively traditional. After collecting blood smear samples, they are placed directly on the table or on various file racks. They are then sorted and collected after drying before being placed in the freezer.
[0003] Traditional drying methods involve directly heating the slide with a hairdryer. However, this method has drawbacks. When the heated air blows onto the slide, it can cause the slide to shift or become too hot in certain areas, which can damage the microorganisms. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a rapid preparation device for multi-specification microbial smears.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A rapid preparation device for multi-size microbial smears, including:
[0007] The base has multiple slide slots arranged in an array on its top surface;
[0008] A through-hole plate is fixedly installed in the middle of multiple slide slots in the vertical direction, and a cavity is formed between the bottom of the multiple slide slots and the through-hole plate.
[0009] A drying component, which is connected to the base via a snap-fit mechanism, includes:
[0010] A rectangular ventilation duct with openings on its left and right sides;
[0011] A fan is provided on the left and right sides of a rectangular ventilation duct, and heating rollers are provided on the moving path of the fan blowing air.
[0012] Two baffles are fixedly installed at the bottom of the rectangular ventilation duct, and the surface of the baffles is provided with holes, with the microbial area of the smear located between the two baffles;
[0013] The air outlet is arranged in an array at the bottom of the rectangular ventilation pipe and is located on the outside of the two baffles, corresponding to the position of the slide slot. The interior of the air outlet is connected to the interior of the rectangular ventilation pipe.
[0014] When the fan starts, hot air enters the air outlet, is pressurized, and is then ejected. The hot air comes into contact with the baffle plate and the through-hole plate, reducing the air speed.
[0015] Preferably, the through holes of the through-hole plate are evenly distributed in an array, and the diameter of the through holes is 0.5mm-2mm. The through holes in the through-hole plate have an inverted conical structure, and the diameter of the hole on the side near the substrate groove is larger than the diameter of the hole on the side near the cavity.
[0016] Preferably, the holes formed on the wind deflector are inclined holes, and the angle between the inclined holes and the bottom of the substrate groove is 120°-150°.
[0017] Preferably, the overall shape of the slide slot is rectangular.
[0018] Preferably, the bottom of the slide tray is provided with an anti-slip pad to prevent the slurry from sliding during the preparation process.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] The perforated plate blocks the hot air blown by the fan. The blocked hot air has a reduced wind speed. Part of the hot air comes into contact with the microorganisms on the top of the smear through the baffle plate for drying, while the other part of the hot air comes into contact with the bottom of the smear through the perforated plate. This achieves all-round coverage of the top, bottom and center of the smear and buffers the wind speed of the hot air. It avoids uneven drying or omissions, ensures consistent drying effect, and prevents strong winds from damaging the sample on the smear. This ensures the integrity and original state of the sample and provides a reliable sample for subsequent observation and analysis. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0028] Example
[0029] like Figure 1 As shown, the multi-size microbial smear rapid preparation device includes:
[0030] The base 1 has multiple slide slots 3 arranged in an array on its top surface;
[0031] A through-hole plate 4 is fixedly installed in the middle of multiple slide slots 3 in the vertical direction, and a cavity is formed between the bottom of the multiple slide slots 3 and the through-hole plate 4.
[0032] Drying component 2, which is connected to base 1 via a snap-fit, includes:
[0033] A rectangular ventilation duct with openings on its left and right sides;
[0034] Fan 5 is set on the left and right sides of the rectangular ventilation duct, and heating rollers 8 are set on the moving path of the fan 5 blowing air.
[0035] Two baffles 6 are fixedly installed at the bottom of the rectangular ventilation pipe, and the surface of the baffles 6 is provided with holes, and the microorganisms on the smear are located between the two baffles 6.
[0036] The air outlet 7 is arranged in an array at the bottom of the rectangular ventilation pipe and is located on the outside of the two baffles 6, corresponding to the position of the slide slot 3. The interior of the air outlet 7 is connected to the interior of the rectangular ventilation pipe.
[0037] When the fan 5 is started, hot air enters the air outlet 7 and is then expelled after being pressurized. The hot air comes into contact with the baffle plate 6 and the through-hole plate 4, and the wind speed decreases.
[0038] Specifically, when drying the film is required, open the clips, and then remove the drying element 2 as a whole using the handle fixed to the rectangular ventilation pipe. Place the film into the film tray 3 above the base 1. After placement, connect the drying element 2 to the base 1 using the clips. At this point, the two baffles 6 contact the surface of the film. The heating roller 8 and fan 5 are then activated, blowing hot air directly to the air outlet 7. The air outlet 7 sprays out the hot air, which is directly blown onto the perforated plate 4. After being blocked by the perforated plate 4, the wind speed decreases, and some of the hot air changes direction towards the perforated plate 4. The hot air moves to both sides, passing directly between the two baffles 6 to contact the central microorganisms of the smear and dry them. A portion of the hot air also passes directly through the perforated plate 4 and enters below it, contacting the lower surface of the smear and drying it. This achieves comprehensive coverage of the smear, including the top, bottom, and center, while also buffering the hot air velocity. This prevents uneven drying or omissions, ensuring consistent drying results while preventing strong winds from damaging the sample, thus maintaining sample integrity and original condition, and providing a reliable sample for subsequent observation and analysis.
[0039] In this embodiment: the through holes of the through-hole plate 4 are evenly distributed in an array, and the diameter of the through holes is 0.5mm-2mm. The through holes at the through-hole plate 4 have an inverted conical structure, and the diameter of the hole on the side closer to the slide groove 3 is larger than the diameter of the hole on the side closer to the cavity.
[0040] Specifically, when hot air enters the cavity directly through the perforated plate 4, it is recirculated and passes through the perforated plate 4 again to reach the bottom of the substrate tray 3. At this time, the inverted conical perforation can guide the hot air to diffuse out after passing through the perforation, increasing the contact area between the hot air and the substrate, allowing all parts of the substrate to fully contact the hot air, and further improving the uniformity of drying.
[0041] In this embodiment: the hole formed on the wind deflector 6 is an inclined hole, and the angle formed between the inclined hole and the bottom of the slide groove 3 is 120°-150°.
[0042] Specifically, hot air comes into direct contact with the smear through the holes in the baffle plate 6. The 120°-150° inclined holes in the baffle plate 6 can precisely guide the hot air through the through-hole plate 4 to the central microbial area of the smear. This angle allows the hot air to enter between the two baffle plates 6 with a specific inclined trajectory, avoiding disorderly diffusion of the hot air and ensuring that the hot air acts on the core detection area of the smear to the greatest extent, improving the drying efficiency and quality of key areas, and ensuring that the sample drying effect meets the detection requirements.
[0043] In this embodiment, the overall shape of the slide slot 3 is rectangular.
[0044] Specifically, the rectangular shape can be adapted to most coatings on the market, thus facilitating the preservation of various coatings and improving the practicality of the device.
[0045] In this embodiment, the bottom of the slide tray 3 is provided with an anti-slip pad to prevent the smear from sliding during the preparation process.
[0046] Specifically, when the smear is placed above the slide tray 3, the lower surface of the smear comes into contact with the upper surface of the anti-slip pad, thereby increasing the friction and effectively preventing the smear from sliding during preparation. This avoids sample damage and changes in microbial distribution caused by smear displacement. Especially in operations such as hot air drying and smear transfer, stable placement can reduce the risk of accidental scratching and contamination of the sample, ensuring that the sample remains in its original state and providing a reliable sample basis for subsequent detection and analysis.
[0047] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
