[0027] The beneficial effects of the present utility model:
[0028] In a first aspect, by providing an ultrasonic transducer on the staining shell and internally installing a resonance member, when the treatment pool needs to be cleaned, first add cleaning liquid into the treatment pool. The cleaning liquid can have a certain effect of soaking and flushing the solid components attached to the side wall of the treatment pool. At this time, start the ultrasonic transducer. The ultrasonic transducer can generate ultrasonic waves, and the ultrasonic waves are transmitted to the resonance member to cause resonance, thereby forming a large vibration. The vibration is then transmitted to the treatment pool to detach the solid components attached to the inner wall of the treatment pool. Then, drain the cleaning liquid. As the cleaning liquid flows, the solid components will be carried away from the treatment pool to complete the cleaning. In this way, when the staining device is being cleaned, there is no need to disassemble the treatment pool. By cooperating with the cleaning liquid, the ultrasonic transducer and the resonance member, the solid components in the treatment pool can be quickly carried away from the treatment pool. This can not only ensure that the solid components do not remain in the treatment pool, effectively reducing the possibility of solid components adhering to the glass slide and reducing the possibility of interference during the observation of the glass slide, but also simplify the process of cleaning the treatment pool, reduce the cleaning difficulty, and improve the cleaning efficiency.

After the sample is dried, the glass slide is placed in the staining device for staining treatment. After the staining is completed, there is no need to disassemble the treatment pool. By cooperating with the ultrasonic transducer and the resonance member, the cleaning of the treatment pool can be quickly completed. This not only effectively reduces the possibility of solid components adhering to the treatment pool, but also avoids disassembling the treatment pool during the cleaning process, effectively simplifies the cleaning process, reduces the cleaning difficulty, and improves the cleaning efficiency.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.
[0041] The embodiment of the present utility model discloses a staining device and a blood smear preparation device.
[0042] Refer to Figures 1 to 4, the staining device includes a staining shell 1, an ultrasonic transducer 2, and a resonance member 3. A plurality of non-communicating treatment pools 4 are distributed at intervals in the staining shell 1, and a solution for treating the glass slide 10 is contained in each treatment pool 4; the ultrasonic transducer 2 is arranged in the staining shell 1 and the transmitting end for emitting ultrasonic waves faces the treatment pool 4; the resonance member 3 is arranged between the staining shell 1 and the treatment pool 4, one side of the resonance member 3 corresponds to the ultrasonic transducer 2, and the other side is connected to the treatment pool 4.
[0043] Specifically, the staining shell 1 can be in a long strip shape or a disc shape, etc., and its top wall is open to facilitate the placement of a plurality of treatment pools 4 in the staining shell 1. The treatment pool 4 can be snap-fitted and fixed to the staining shell 1, or fixed by fasteners such as bolts to form a detachable connection between the treatment pool 4 and the staining shell 1. A plurality of treatment pools 4 can also be fixedly connected together through a connecting portion 41 and installed in the staining shell 1 together. The treatment pool 4 can include two types: a staining pool and a cleaning pool. In this embodiment, five treatment pools 4 are provided, and the specific numbers of the staining pool and the cleaning pool can be set according to the requirements of the staining operation. An opening can be provided at the lower end of the treatment pool 4 to facilitate the discharge of the solution after the treatment is completed. A plurality of convex ribs are also distributed at intervals on the side wall of the treatment pool 4, and the distance between adjacent two convex ribs is slightly larger than the distance between the glass slides 10, so that each treatment pool 4 can insert a plurality of glass slides 10 at the same time.
[0044] The ultrasonic transducer 2 is arranged on the side of the staining shell 1, and its transmitting end is located inside the staining shell 1 and faces the treatment pool 4 directly. Its model and size can be selected according to the shape and size of the staining shell 1. A resonance member 3 is arranged between the treatment pool 4 and the staining shell 1. The resonance member 3 can be in a plate shape, a shell shape, or other shapes, as long as it can resonate with the ultrasonic waves generated by the ultrasonic transducer 2 to achieve the effect of amplifying the vibration. The resonance member 3 can be directly attached to the treatment pool 4 or connected through other connection structures to facilitate the transmission of the vibration to the treatment pool 4.
[0045] By arranging an ultrasonic transducer 2 on the dyeing shell 1 and internally installing a resonance member 3, when it is necessary to clean the processing tank 4, first add a cleaning liquid into the processing tank 4. The cleaning liquid can have a certain soaking and scouring effect on the solid components attached to the side wall of the processing tank 4. At this time, start the ultrasonic transducer 2. The ultrasonic transducer 2 can generate ultrasonic waves, and the ultrasonic waves are transmitted to the resonance member 3 to cause resonance, thereby forming a larger vibration. The vibration is then transmitted to the processing tank 4 to detach the solid components attached to the inner wall of the processing tank 4. Then, drain the cleaning liquid. As the cleaning liquid flows, the solid components will be carried away from the processing tank 4 to complete the cleaning. In this way, when the dyeing device is being cleaned, there is no need to disassemble the processing tank 4. By using the cooperation of the cleaning liquid, the ultrasonic transducer 2 and the resonance member 3, the solid components in the processing tank 4 can be quickly carried away from the processing tank 4. This can not only ensure that no solid components remain in the processing tank 4, effectively reducing the possibility of solid components adhering to the glass slide 10 and reducing the possibility of interference when observing the glass slide 10, but also simplify the process of cleaning the processing tank 4, reduce the cleaning difficulty, and improve the cleaning efficiency.
[0046] Optionally, the resonance member 3 is a resonance shell, and a resonance shell is sleeved outside each processing tank 4.
[0047] Specifically, the shape of the resonance shell can be adapted to the shape of the processing tank 4. In this embodiment, the processing tank 4 is cube-shaped, so the resonance shell is also cube-shaped. It is sleeved outside the processing tank 4, and each processing tank 4 is separately sleeved with a resonance shell, which can reduce the size and weight of a single resonance shell, enabling each resonance shell to form vibrations that meet the cleaning requirements when receiving ultrasonic waves. Moreover, each processing tank 4 being separately provided with a resonance shell can also increase the contact area between the resonance shell and the processing tank 4, thereby improving the vibration transmission effect.
[0048] Optionally, the inner side surface of the resonance shell is attached to the outer side wall of the processing tank 4.
[0049] Specifically, a surface contact is formed between the resonance shell and the processing tank 4 so that the vibration of the resonance shell can be quickly and effectively transmitted into the processing tank 4. It should be understood that in other embodiments, the resonance shell and the processing tank 4 can also be connected in other ways. For example, a very small gap can be formed between the processing tank 4 and the resonance shell to ensure that the resonance shell has enough space to vibrate and can still form effective contact with the processing tank 4 during vibration to transmit the vibration. It can be specifically designed according to the actual installation space as long as it can effectively transmit the vibration.
[0050] Optionally, the side wall of the resonance shell is hollow.
[0051] Specifically, the resonance shell can be made of plastic material. The top wall of the resonance shell is open to accommodate the treatment tank 4, and the four side walls of the resonance shell can all be hollow, and the bottom wall of the resonance shell can also be hollow, so as to effectively reduce the weight of the resonance shell itself, ensuring that the ultrasonic transducer 2 can smoothly cause the resonance of the resonance shell.
[0052] Optionally, an ultrasonic transducer 2 is correspondingly arranged for each treatment tank 4.
[0053] Specifically, a plurality of partitions are distributed at intervals on the inner wall of the dyeing shell 1 to form a plurality of treatment cavities. A treatment tank 4 is placed in each treatment cavity, and an ultrasonic transducer 2 is correspondingly installed in each treatment cavity to improve the working efficiency of the ultrasonic transducer 2. It should be understood that according to the cleaning effect, multiple ultrasonic transducers 2 can also be arranged for each treatment tank 4, and the multiple ultrasonic transducers 2 respectively correspond to different sides of the resonance shell. The specific number and arrangement position of the ultrasonic transducers 2 can be designed according to the actual cleaning effect, and are not limited to the examples given in the embodiments and the drawings.
[0054] Optionally, a plurality of through holes are formed through the resonance member 3.
[0055] Specifically, a plurality of through holes are formed in the resonance member 3, and the plurality of through holes are distributed circumferentially around the resonance member 3. In this embodiment, the five walls of the resonance member 3 are all provided with through holes distributed in an array. The formation of the through holes can not only further reduce the weight of the resonance member 3, but also enable the ultrasonic waves generated by the ultrasonic generator to directly act on the treatment tank 4, so as to further improve the vibration effect of the treatment tank 4. When the through holes are formed, the inner cavity of the side wall of the resonance member 3 is closed to prevent the solution in the treatment tank 4 from flowing into the inside of the resonance member 3.
[0056] Optionally, the resonance member 3 covers the drain port of the treatment tank 4.
[0057] Specifically, a liquid outlet is formed on the side surface of the dyeing shell 1, and a drain channel is arranged inside the dyeing shell 1. The drain ports of the plurality of treatment tanks 4 can all communicate with the drain channel. When the dyeing treatment is completed, the solution can flow to the liquid outlet through the drain port and the drain channel and be discharged along the liquid outlet pipeline. When the glass slide 10 is broken and falls into the treatment tank 4, small particle fragments can be discharged through the through holes of the resonance member 3, while large particle fragments are retained by the resonance member 3. When the resonance member 3 is a resonance shell, it can be sleeved outside the treatment tank 4, so as to effectively retain large particle fragments in the resonance sleeve, reducing the possibility of large particle fragments entering the pipeline and causing damage or blockage.
[0058] Optionally, the dyeing device further includes a detector 5. The detector 5 is disposed on the outer sidewall of the dyeing housing 1, and an induction part 42 corresponding to the detector 5 can be provided on the treatment tank 4. In this embodiment, the five dyeing tanks are divided into two groups, and the dyeing tanks in each group are fixedly connected together through a connecting part 41. Then, two detectors 5 are correspondingly provided, and only one induction part 42 needs to be provided for each group of dyeing tanks. The detector 5 can adopt an optocoupler sensor or other sensors that meet the detection requirements.
[0059] By providing the detector 5, when the treatment tank 4 is installed, as long as it is ensured that the induction part 42 can correspond to the detector 5 and trigger the detector 5, it can be determined that the treatment tank 4 has been installed in place, which is convenient for the operator to install.
[0060] Optionally, the dyeing device further includes a receiving tank 6. The receiving tank 6 is disposed outside the dyeing housing 1 and communicates with a plurality of treatment tanks 4.
[0061] Specifically, the receiving tank 6 is provided outside the dyeing housing 1. The receiving tank 6 can be arranged along the outside of the dyeing housing 1. The top of the receiving tank 6 is open to accommodate the solution overflowing from the treatment tank 4.
[0062] Refer to Figure 4 and Figure 5 Optionally, the dyeing device further includes a drying housing 7, a drying tank 8, and a drying fan 9. The drying housing 7 is disposed on the dyeing housing 1; the drying tank 8 is disposed inside the drying housing 7, and a plurality of ventilation holes 81 are formed through the sidewall of the drying tank 8. The drying fan 9 is disposed in the drying housing 7, and the air outlet of the drying fan 9 faces the air inlet of the drying tank 8.
[0063] Specifically, the drying housing 7 is fixedly provided outside the dyeing housing 1, and the fixing method can be welding, bonding, or bolt connection, etc. The drying tank 8 is inserted into the drying housing 7. A pressing plate 71 is provided on the drying housing 7. The pressing plate 71 is bolted to the top wall of the drying housing 7, and the bottom wall of the pressing plate 71 can press on the top wall of the drying tank 8 to fix the drying tank 8 in the drying housing 7.
[0064] On the inner wall of the drying tank 8, a plurality of convex ribs are distributed at intervals, and a glass slide 10 can be inserted between two adjacent convex ribs. An air inlet is provided on the side of the drying tank 8. At the position corresponding to the air inlet on the drying shell 7, a wind guide port is provided. On the side of the wind guide shell, a connecting plate 72 is connected by bolts, and the drying fan 9 is fixed on the connecting plate 72, and the air outlet of the drying fan 9 corresponds to the wind guide port. The drying fan 9 can be a heating type fan, and a temperature sensor 73 is provided on the drying shell 7 to detect the temperature of the air blown out by the drying fan 9 in real time. Moreover, the drying fan 9 can also adjust the power and temperature to flexibly adjust the operating performance of the drying fan 9 according to the data detected by the temperature sensor 73, so as to ensure that the glass slide 10 is dried in the wind with the best temperature and intensity.
[0065] On the side wall of the drying tank 8, a plurality of ventilation holes 81 are also provided at intervals. The ventilation holes 81 can be waist-shaped, and the plurality of ventilation holes 81 are equally spaced. The ventilation holes 81 can also be circular and arranged in an array. A liquid receiving pool 74 is also inserted into the bottom wall of the drying shell 7. The liquid receiving pool 74 is located below the drying tank 8 to receive the liquid dripping from the glass slide 10.
[0066] By arranging the drying shell 7 outside the staining shell 1, the glass slide 10 can be quickly inserted into the drying tank 8 for drying after the staining treatment is completed. When drying, the wind is generated by the drying fan 9, and the wind blows into the drying tank 8. Moreover, the drying tank 8 is not only provided with an air inlet, but also provided with ventilation holes 81, so that the wind can enter the drying tank 8 from all around to fully contact the glass slide 10, thereby effectively improving the drying efficiency of the glass slide 10 and enabling each part of the glass slide 10 to be dried simultaneously, thus effectively improving the drying effect of the glass slide 10.

The smearing device is used for smearing the glass slide 10; the drying device is used for drying the smeared glass slide 10; the staining device is used for staining the dried glass slide 10.
[0068] When the blood smear preparation device is in use, the sample is coated on the glass slide 10 by using the smearing device. After the sample is dried, the glass slide 10 is placed in the staining device for staining treatment. After the staining is completed, it is not necessary to disassemble the treatment tank 4. The ultrasonic transducer 2 and the resonance member 3 can be used in cooperation to quickly complete the cleaning of the treatment tank 4, which not only effectively reduces the possibility of solid components adhering to the inside of the treatment tank 4, but also avoids disassembling the treatment tank 4 during the cleaning process, effectively simplifies the cleaning process, reduces the cleaning difficulty, and improves the cleaning efficiency.
