Description

Technical Field

[0001] The invention relates to a method and a device for simulating optimal parameters for preparing a chromosome sample slide, and belongs to the technical field of chromosome preparation. Background Art

[0002] The final effect of chromosome preparation needs to be judged by manual microscopic examination. The chromosome preparation process involves three links: culture, harvesting, and slide preparation (staining). Specifically, for the final effect of slide preparation, the current general practice is for professional pre-treatment process personnel to randomly select a slide from the currently prepared batch of slide samples, and use a biological microscope to observe the number of cells, the number and dispersion of mitotic phases, and staining, so as to judge the quality of cell culture harvest and the quality of slide preparation and staining.

[0003] With the development of laboratory automation equipment, chromosome preparation has gradually changed from early manual single operations to manual operation of single-function equipment to achieve a complete process. However, the following problems still exist:

[0004] 1. The preparation process is highly dependent on manual experience, and parameter adjustment is complex and time-consuming.

[0005] The performance of equipment and reagents from different manufacturers varies greatly, and manual exploration is required to improve the production effect, which is time-consuming and laborious. In the cytogenetics laboratory, "probing" is a critical and complex step that directly affects the quality of chromosome preparation.

[0006] Since the operation process is more dependent on manual labor and the factors that affect the final sample preparation effect are more complex, operators need to find the best parameters through repeated experiments and experience accumulation, which greatly increases the time and labor costs of the laboratory. In addition, even if the best parameters are found, due to differences between batches and differences in human operations, they still need to be constantly fine-tuned, which further increases the workload and complexity.

[0007] 2. The process is complicated and lacks an overall automation solution.

[0008] The entire process is relatively complicated. There is currently no equipment on the market that automates the entire process. Most of the equipment in each link exists separately, such as the independent inoculation equipment, incubators, harvesting instruments, slicing equipment, ovens and staining instruments that are commonly seen on the market.

[0009] 3. The equipment module has low integration, requiring frequent manual intervention, increasing the risk of contamination and errors.

[0010] The equipment module has a low integration level and cannot run through the entire process automatically. It requires manual intervention after each process is completed and operates the next process to finally complete the entire sample processing. In addition, manual microscopy is still required to judge the final preparation effect.

[0011] This decentralized equipment configuration and manual operation intervention not only increases the workload of the laboratory, but may also lead to problems such as inconsistent results and poor repeatability. Manual transfer and operation between each link increases the risk of sample contamination and errors, and also prolongs the time of the entire preparation process. In addition, due to the lack of real-time monitoring and automatic adjustment mechanisms, the quality control of the entire process mainly depends on the experience and judgment of the operator, which may lead to batch-to-batch differences and instability.

[0012] The information disclosed in this Background Art is only for understanding the background of the inventive concept and therefore it may include information that does not constitute the prior art. Summary of the invention

[0161] A method for preparing chromosome sample slides, which automatically evaluates the slide making effect, automatically adjusts the process parameters such as culture, centrifugation, drop slide, digestion and staining as needed, and re-slides until the ideal slide making effect is obtained and then enters the batch slide making stage to achieve the best slide making effect; the specific contents are as follows:

[0162] Preliminary slide preparation: The sample enters the slide preparation and staining machine, and preliminary slide samples are prepared through operations such as dropping, baking, digestion and staining.

[0163] Slide preparation evaluation: The sample slide is transferred to the automatic microscopic scanning system, which uses the automatic scanning function to evaluate the number of metaphases, chromosome length, dispersion degree and banding effect on the slide.

[0164] Effect judgment: If the production effect does not meet the standard (such as small number of mitotic phases, too short chromosomes, severe clustering and crossing, or unclear banding), the system automatically enters the parameter adjustment stage; if the effect is qualified, the process enters the batch production stage.

[0165] Parameter adjustment: The system automatically adjusts key parameters such as incubation time and temperature, centrifugation speed and time, drop height and angle, digestion time and staining conditions.

[0166] Re-production: After adjusting the parameters, the system will re-produce the film and re-evaluate the production effect. If the effect is still unsatisfactory, the system will continue to adjust the parameters and re-produce until the result meets the requirements.

[0167] Batch production: Once the optimal production parameters are confirmed, the system will use these parameters as the standard for batch production to ensure that the quality of each batch of samples is consistent and suitable for subsequent karyotype analysis and clinical diagnosis.

[0168] like Figure 3 As shown, the second specific embodiment of the device for preparing chromosome sample slides of the present invention:

[0169] A chromosome sample slide preparation device consists of five main modules: an inoculation culture instrument, an automatic cell harvester, a slide preparation and staining all-in-one machine, an automatic cell microscopic scanning system and a control system.

[0170] Among them, the inoculation culture instrument, automatic cell harvester, slide preparation and staining machine, and automatic cell microscopy scanning system are all controlled by a unified control system, which automatically completes the process and transmission of materials from front to back under program control. The process and transmission process between each module are automated to ensure that the sample completes the preparation process at each stage in each submodule and the series process between each submodule is connected. Specifically, the processing mechanism of each module is as follows:

[0171] The inoculation incubator is used to automatically complete the inoculation and cultivation of samples. The specific processing flow includes:

[0172] Sample inoculation: The manually input blood sample is inoculated on the culture medium through the built-in robotic arm to ensure sterile operation.

[0173] Environmental control: The incubator has built-in temperature and humidity sensors that can automatically adjust the environmental conditions inside the box to maintain appropriate culture temperature and humidity.

[0174] Automatic transfer: After the culture is completed, the culture medium is automatically transferred by the conveyor belt to the next submodule, the automatic cell harvester.

[0175] The automatic cell harvester is responsible for receiving the culture medium from the inoculation culture instrument and performing a series of processing operations. The specific processing flow includes:

[0176] Add colchicine: The system automatically adds an appropriate amount of colchicine to block cell division.

[0177] Centrifugation: Samples are centrifuged to separate the cell pellet and supernatant.

[0178] Discard supernatant: Automatically aspirate to discard supernatant and retain cell pellet.

[0179] Add hypotonic oscillation: Automatically add hypotonic solution and swell the cells by oscillation.

[0180] Add fixative: automatically add fixative to fix cell morphology.

[0181] Centrifuge again and discard the supernatant: Perform a second centrifugation and discard the supernatant to ensure a purer cell population, providing better material for subsequent chromosome preparation and analysis.

[0182] Automatic transfer: After the automatic cell harvesting is completed, the system automatically transfers the samples to the slide preparation and staining machine.

[0183] The slide preparation and staining machine is used to prepare the processed cell samples on the slides and perform digestion and staining to obtain the final slide samples that can be used for chromosome scanning and analysis under the microscope system. The specific processing flow includes:

[0184] Slide preparation: The processed cell suspension is automatically dropped onto a glass slide by a pipette device, and the cells are spread and dispersed on the slide to form a thin layer for observation under a microscope.

[0185] Slide baking: The all-in-one machine integrates a slide baking device with adjustable temperature and time. It automatically places the prepared slides in the preheated slide baking device, dries the samples by constant temperature baking, and quickly fixes the cells, ensuring that the cell morphology and structure remain stable during the preparation process.

[0186] Digestion: Use a robot to grab the frosted area of ​​the slide, place the cell sample area of ​​the slide in a digestion tank, and use trypsin to treat the cells to break down the proteins between cells, separate the cells, remove the connecting substances between cells, and disperse the chromosomes for easy observation and analysis.

[0187] Rinsing: Wash the digested slides with an appropriate buffer (such as phosphate buffered saline) to remove residual enzymes, culture medium components or other impurities, which helps prevent background interference during staining and ensures the clarity of chromosomes.

[0188] Staining: The frosted area of ​​the slide is grabbed by a robot, and the cell sample area of ​​the slide is immersed in a staining jar. The chromosomes are stained with specific dyes (such as Giemsa dye) to make the banding characteristics of the chromosomes more visible and the structure clearer, which is convenient for chromosome analysis and identification.

[0189] Automatic transfer: Automatically transfer the prepared slides to the automatic cell microscopy scanning system.

[0190] The automatic cell microscopy scanning system is used to fully automatically scan and capture images of stained slides for chromosome karyotype analysis. The specific processing flow includes:

[0191] Automatic positioning: The fully automatic slide retrieval assembly pulls the slide to the stage, and the high-precision stage automatically positions the slide scanning area.

[0192] Intelligent scanning: The automatic microscopic imaging system includes a fully automatic stage, an automatic focusing system, optical imaging and a high-definition camera device, which automatically scans the slide scanning area in all directions to obtain high-definition cell images.

[0193] Data storage: Automatically store scanned cell images to facilitate chromosome karyotype analysis and archiving.

[0194] The control system is the core of the entire automated experimental device, which is used to coordinate the operation of each module to ensure the automated operation of the entire process and the unified management of data. It is mainly composed of a central processing unit (CPU), a data processing module, a sensor network, and a security monitoring module, and is responsible for the following functions:

[0195] System integration and process scheduling: The control system coordinates the work of various modules such as the inoculation culture instrument, cell harvester, slide preparation and staining machine, automatic cell microscopy scanning system, etc. in real time through the central processing unit (CPU) and embedded control program to ensure seamless connection according to the predetermined process flow.

[0196] Real-time monitoring and feedback adjustment: The control system integrates a variety of sensors (such as temperature, humidity, pressure, liquid level, position sensors, etc.) to monitor the status and process parameters of each module in real time. Through the feedback data of these sensors, the control system can dynamically adjust the operation of each sub-module. For example, when the temperature deviation during the culture process is collected, the system will automatically adjust the temperature in the incubator; during the preparation process, if the drop height or cell distribution is abnormal, the system will correct it by adjusting the movement of the robotic arm. This type of feedback adjustment mechanism ensures the accuracy and consistency of sample processing.

[0197] Data management and information traceability: The control system integrates a data management module to automatically record and track every step of the sample operation to ensure the uniqueness and traceability of the information. When the sample enters the system, the system will automatically identify and encode it to ensure the uniqueness of the sample information. The system tracks the processing status of the sample in each module, including culture time, harvesting conditions, preparation and staining parameters, to ensure the traceability of the entire process.

[0198] Operational safety and fault handling: The control system uses a built-in safety monitoring mechanism to detect the operating status of the equipment in real time to ensure safety during the work process. The sensor monitors key parameters such as temperature, pressure and liquid level in real time, and automatically alarms and shuts down when an abnormality occurs to prevent sample damage or equipment failure. The system has automatic shutdown and fault self-diagnosis functions, which can save current data, generate fault reports, and prompt operators to perform maintenance in the event of a fault, ensuring the continuity and safety of the work process.

[0199] The control system is not just a simple module coordination device. It ensures the efficient, stable and safe operation of the entire automated experimental device through efficient information processing, real-time monitoring feedback, refined data management and intelligent optimization functions. The system can monitor the progress of sample processing throughout the process and provide an immediate response mechanism in abnormal situations, thereby ensuring the accuracy and traceability of each sample from inoculation to final analysis. Through this highly integrated and intelligent control system, human intervention and operational errors are greatly reduced, and the laboratory's automation level, data reliability and sample processing efficiency are significantly improved.

[0200] A specific embodiment of the method and preparation device of the present invention is as follows:

[0201] The main factors that affect the preparation of chromosome slides include sample quality, inoculation and harvesting time, culture medium and various reagents used (such as colchicine, trypsin, etc.), preparation and staining operations, environmental control, etc. These factors will directly affect the quality of the final chromosomes, and thus affect the accuracy of subsequent analysis. Although some factors can be reasonably controlled through some equipment and standardized operations, changes in the performance of culture media and reagents may still affect the preparation effect, and the impact on the results cannot be completely eliminated.

[0202] To this end, the present invention adds a film scanning system with a film production effect evaluation function to the preparation device to ensure that the best film production effect is obtained in the batch film production process. When the system replaces different reagents, it first produces films according to the set film production conditions, and evaluates the film production effect by scanning the film. If the effect is not up to standard, the system will automatically adjust the film production parameters according to the set influencing factors, and re-produce until the film production effect meets the requirements. Finally, the system will achieve batch production based on the qualified film production parameters.

[0203] Slide preparation effect evaluation function: After slide preparation, the control system automatically transfers the sample slide to the slide scanning system for scanning and analysis. The system automatically detects the number and quality of metaphases on the slide, including chromosome length, dispersion, and banding staining. Slides with a large number of mitotic phases and good quality are more conducive to subsequent analysis and research, so the system will give priority to retaining such slides for karyotype analysis and clinical research. For samples with poor slide preparation, the system will automatically adjust based on influencing factors.

[0204] The main factors that affect the effect of chromosome slide preparation are as follows:

[0205] The effect of chromosome slide preparation is affected by many factors, including the quality of the sample itself, the control of environmental conditions during the preparation process, and the setting of various process parameters. Specifically, the following are several major influencing factors:

[0206] Sample quality: The health, activity and cell status of the sample directly affect the final film production results. Poor quality samples will lead to insufficient number of mitotic phases, affecting the distribution of chromosomes and banding effects.

[0207] Inoculation and harvesting time: The length of culture time and the timing of cell harvesting are crucial to the production effect. If the culture time after inoculation is too short, the cells may not be able to fully proliferate, resulting in insufficient number of mitotic phases; if the culture time is too long, the cells may enter the late mitotic phase, and the chromosomes may be too short to affect subsequent analysis.

[0208] Performance of culture medium and reagents: Colchicine, trypsin and other reagents play a role in blocking cell division and digesting intercellular matrix during the preparation process. The activity of reagents in different batches varies, which will have a direct impact on the state of cell division phase, chromosome dispersion and banding effect.

[0209] Centrifugation conditions: The centrifugal speed and time affect the sedimentation and concentration of cells. If the centrifugation conditions are inappropriate, it may lead to uneven distribution or excessive aggregation of cells, affecting the droplet effect.

[0210] Dropping operation: The height, angle and diffusion of the liquid during the drop directly determine the distribution of cells on the slide. If the drop height is too high, it may cause cell rupture and uneven chromosome dispersion; while if it is too low, it may cause cells to aggregate too much and chromosomes to overlap.

[0211] Digestion time: Digestion time determines the degree of chromosome separation. Too short a digestion time will result in incomplete chromosome separation and severe clustering and crossing; too long a digestion time may lead to over-digestion of chromosome structure and unsatisfactory banding and staining.

[0212] Staining time and environmental conditions: Staining time, dye concentration, temperature and humidity during the staining process affect the chromosome banding effect. If the staining time is too short, the banding will be unclear, while if the time is too long, the staining may be too dark, affecting the resolution of the chromosome.

[0213] Furthermore, the method and preparation device of the present invention are used to dynamically monitor the preparation effect, automatically optimize various key parameters, and ensure high-quality chromosome preparation. The specific process is as follows:

[0214] Step 1. Conduct film production evaluation. The specific method is as follows:

[0215] After completing the preliminary preparation, the system evaluates the preparation effect based on the preset preparation conditions (such as culture temperature, culture time, centrifugal speed and time, drop height and angle, digestion time, staining time, etc.). Through the scanning system, the number of metaphases, chromosome length, dispersion degree and banding quality are analyzed. If the evaluation results show that the number of mitotic phases is large, the chromosome length is moderate and the dispersion effect is good, it means that the preparation is qualified; if the evaluation does not meet the standards, the system will automatically adjust the corresponding parameters.

[0216] Step 2. Adjust the parameters. The specific method is as follows:

[0217] If the production effect is not ideal (such as small number of mitotic phases, chromosomes are too short, severe clustering and crossing, or unclear banding), the system will automatically adjust the following key parameters:

[0218] Culture time and temperature: If the number of mitotic phases is insufficient, the culture time of the cells can be appropriately extended, or the culture temperature can be fine-tuned to promote cell proliferation. Extending the culture time can increase the number of mitotic phases, and adjusting the temperature can optimize cell growth conditions.

[0219] Centrifugation speed and time: Centrifugation conditions affect the sedimentation state of cells. If the cells are unevenly distributed or over-aggregated, the system will reduce the centrifugation speed or shorten the centrifugation time to ensure that the cells are evenly distributed on the slide.

[0220] Droplet height and angle: If the chromosome dispersion is not ideal, the system will optimize the distribution of cells on the slide by adjusting the droplet height or angle. Adjusting the droplet height can improve cell breakage, while adjusting the angle helps cells spread evenly.

[0221] Digestion time: If the chromosomes are poorly dispersed or severely aggregated, the system will extend the digestion time to ensure effective chromosome separation; if the chromosomes are excessively banded, the digestion time should be appropriately shortened.

[0222] Staining time and conditions: If the band is not clear, the system will extend the staining time; if the staining is too dark, it will shorten the staining time. At the same time, the system will also check and adjust the temperature and humidity in the staining environment to ensure the best reaction effect of the stain.

[0223] Step 3. Re-filming and evaluation. The specific method is as follows:

[0224] After the parameters are adjusted, the system will re-perform the production operation and evaluate the production effect again. If the new production effect meets the standard (such as an increase in the number of mitotic phases, moderate chromosome length, good dispersion and clear banding), the system will confirm that the adjusted parameters are effective and enter the next stage; if the effect is still not ideal, the system will continue to make fine adjustments based on feedback until the expected quality is achieved.

[0225] Step 4. Batch production, the specific method is as follows:

[0226] Once the system confirms the optimal production parameters, the adjusted parameters will be used as the standard for subsequent batch production. The system will continue to monitor the quality of the batch production process to ensure that the production effect of each batch is consistent and stable. If the effect fluctuations are detected during the batch production process, the system will automatically make fine adjustments to maintain the high quality output of the samples.

[0227] The present invention can dynamically optimize various key parameters in the production process by combining production effect evaluation and automatic adjustment mechanism to ensure the best chromosome production effect under different conditions. Through real-time feedback and parameter adjustment, the system solves the influence of factors such as reagent variation and environmental fluctuation on the production effect, and significantly improves the stability, efficiency and repeatability of the experiment. After preliminary optimization, the system can achieve efficient batch production, ensure that the sample quality always meets the standard, and provide reliable sample support for subsequent karyotype analysis and clinical diagnosis.

[0228] The present invention provides an automated chromosome preparation device, which realizes the automation and high efficiency of the whole process by integrating the processes of culture, harvesting, slide preparation, staining, microscopic scanning, etc. Compared with the prior art, the present invention is simpler in operation and greatly improves the quality and consistency of slide preparation.

[0229] Furthermore, the present invention adopts an innovative overall integrated design, integrating multiple functional modules such as inoculation, cell harvesting, slide preparation, staining, and microscopic scanning into the same system. Each functional module is seamlessly connected through an automated transmission system, avoiding manual transfer operations between multiple devices. This highly integrated automated design greatly reduces manual intervention, reduces the risk of contamination and operational errors when samples are transferred between different devices, and significantly improves the convenience of operation and the consistency and stability of sample processing.

[0230] The present invention introduces an intelligent slide quality assessment and automatic adjustment mechanism, which can evaluate key indicators on the slide in real time (such as the number of metaphase divisions, chromosome dispersion and band clarity) through an automatic scanning system. If the slide production effect does not meet the standard, the system can automatically adjust the incubation time, centrifugation conditions, drop height, digestion and staining time and other process parameters, and re-slide until the best slide production effect is obtained. This innovative automatic adjustment mechanism ensures the quality consistency of each batch of slide production, greatly reduces the error of human adjustment, and improves the reliability and stability of slide production.

[0231] The present invention realizes the automation of the whole process from sample inoculation, cell harvesting to slide making and staining through an efficient automated operating system, reducing the complexity of manual operation. After optimizing the parameters, the system can perform batch slide making operations to ensure the consistency and efficiency of large-scale sample processing. This innovative automated design greatly improves the laboratory's sample processing capabilities, allowing the laboratory to process a large number of samples in a short period of time, significantly improving work efficiency and meeting the needs of high-throughput experiments.

[0232] Through the above-mentioned innovations, the present invention effectively solves the deficiencies in the prior art, realizes the automation and intelligence of the entire chromosome preparation process, ensures the high quality, stability and consistency of sample processing, and significantly improves the laboratory's work efficiency and operational reliability.
