Description

Technical Field

[0001] The present invention relates to the technical field of laboratory management, and particularly to a laboratory management system and method. Background Art

[0002] There are various types of chemical reagents in the chemical laboratories of pharmaceutical factories or drug research institutions. The storage of chemical reagents is the daily work of laboratory personnel, and requires managers to have a high level of knowledge about chemical reagents. General chemical reagents are stored separately according to simple substances, inorganic substances, organic substances, indicators, etc. The quality of chemical reagents is one of the factors directly affecting the quality of experiments. For some reagents that are not commonly used, managers need to check them regularly to ensure that the reagent packages are intact, the labels are complete, and the handwriting is clear, and to promptly detect whether the chemical reagents have deteriorated for corresponding treatment.

[0003] Currently, the management of reagents in chemical laboratories is usually carried out manually. However, the knowledge levels of different managers in judging the quality of reagents are different, and there is also a large degree of subjectivity in setting the inspection cycle of reagent quality, resulting in poor management effects of laboratory reagents, making it difficult to promptly detect the deterioration of reagents in the laboratory and having an adverse impact on the quality of experiments.

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for use in the embodiments or the description of the prior art. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0035] Figure 1 is a schematic structural diagram of a laboratory management system provided by an embodiment of the present invention;

[0036] Figure 2It is a flowchart for implementing the laboratory management method provided by an embodiment of the present invention. Detailed implementation manners

[0037] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described below through specific embodiments with reference to the accompanying drawings.

[0039] Refer to Figure 1 , which shows a schematic structural diagram of the laboratory management system 1 provided by an embodiment of the present invention. The laboratory management system 1 is applied to a chemical laboratory, and various reagents are stored in the chemical laboratory. The laboratory management system 1 includes an image acquisition module 11, an environmental monitoring module 12, and a management module 13.

[0040] The image acquisition module 11 is configured to acquire reagent images in the chemical laboratory and send them to the management module 13.

[0041] The environmental monitoring module 12 is configured to monitor environmental information in the chemical laboratory and send it to the management module 13.

[0042] The management module 13 is configured to extract the reagent name and appearance information of the reagent from the reagent image, determine the reagent state of the reagent based on the reagent name, appearance information, and environmental information, and manage the reagents in the chemical laboratory based on the reagent state.

[0043] In this embodiment, the reagent specifications in our country are basically divided according to purity (the amount of impurities). There are 7 types in total, namely high purity, spectral purity, primary standard, spectroscopic purity, guaranteed reagent, analytical reagent, and chemical pure. The main 3 types with quality indicators promulgated by the state and competent departments are guaranteed reagent, analytical reagent, and chemical pure.

[0044] ⑴ Guaranteed reagent (GR: Guaranteed reagent), also known as first-class product or guaranteed reagent, with a purity of 99.8%. This reagent has the highest purity and the lowest impurity content, and is suitable for important and precise analytical work and scientific research work. It uses green bottle labels.

[0045] ⑵ Analytical reagent (AR), also known as second-class reagent, with a very high purity of 99.7%. It is slightly inferior to the guaranteed reagent and is suitable for important analysis and general research work. It uses red bottle labels.

[0046] (3) Chemically Pure (CP), also known as third-grade reagent, with a purity of ≥99.5%. The purity is quite different from that of analytical pure, and it is suitable for general analytical work in industrial and mining enterprises and schools. It uses blue (dark blue) labels.

[0047] (4) Laboratory reagent (LR), also known as fourth-grade reagent. In addition to the above four grades, there are currently on the market: Primary Reagent (PT): Specially used as a reference substance and can directly prepare standard solutions. Spectrum pure reagent (SP): Indicates spectral purity. However, since organic substances do not show up in the spectrum, sometimes the main component does not reach more than 99.9%. Attention must be paid when using it, especially when used as a reference substance, calibration must be carried out. Reagents with a purity much higher than that of guaranteed reagent are called high-purity reagents (≥99.99%).

[0048] Currently, the specifications of chemical reagents produced by foreign reagent factories tend to be classified according to their uses. The common ones are as follows: Biochemical reagent (BC), Biological reagent (BR), Biological Stain (BS), For Complexometry (FCM), For chromatographic purpose (FCP), Fluorescence analysis (FIA), For microbiological use (FMB), For microscopic purpose (FMP), For synthesis (FS), Gas chromatography (GC), High Pressure Liquid chromatography (HPLC), Indicator (Ind), Infrared absorption (IR), Liquid chromatography (LC), Nuclear magnetic resonance (NMR), Organic analytical standard (OSA), Pro analysis (PA), Practical use (Pract), Pure (purum pure), Puriss (Purissmum extra pure), Synthesis (SYN), Technical grade (Tech), Thin Layer chromatography (TLC), Spectroscopically pure, Optically pure, Ultra violet pure (UV).

[0049] The primary task in laboratory reagent management is procurement. Therefore, a laboratory should first have a complete system for requisition, approval, purchase, acceptance, warehousing, and requisition. Special attention should be paid to purchasing reagents from regular reagent stores with regular supply channels and producing reagents in accordance with national standards and the industry standards of the Ministry of Chemical Industry. The reagent label should indicate the name (including common name), category, product standard, content, specification, manufacturer, and production batch number (or production date); for some reagents, the shelf life should also be marked.

[0050] General chemical reagents are stored separately according to elements, inorganic substances, organic substances, indicators, etc. Inorganic and organic substances should be stored separately according to the type and specification of the reagents. For some reagents that are not commonly used, the management personnel should conduct regular inspections to ensure that the reagent packaging is intact, the label is complete, and the handwriting is clear. Solid reagents should not show moisture absorption or deliquescence; liquid reagents should not have precipitates. Otherwise, the sealing condition of the reagent should be checked. Special attention should be paid to the inspection of certain reagents, such as whether the oil seal on the surface of potassium and sodium, and the water seal on the surface of white phosphorus and mercury meet the requirements to avoid danger.

[0051] Generally, the remaining reagents after opening are more likely to deteriorate, including:

[0052] a. The change in the shape and state of the reagent, such as sodium hydroxide changing from crystals to powder.

[0053] b. The change in the volume of the reagent, including volatilization and sublimation, such as the reduction of the reagent in the bottle containing iodine, and c. The change in color, such as the discoloration of the test paper after long-term storage, the precipitation in the solutions of mercury dichloride (HgCl2) and silver nitrate (AgNO3); the appearance of white precipitate in the solution of stannous chloride (SnCl2) and the browning of the solution of ferrous sulfate (FeSO4), etc. When the above phenomena occur in the reagent, it can be judged that the reagent has volatilized or deteriorated.

[0054] There are many reasons for reagent deterioration. Different reagents have different reasons for deterioration and cannot be generalized. Sealing, light exposure, moisture absorption, temperature rise, etc. of the reagent may all cause the reagent to deteriorate. Some reagents are prone to volatilization and deterioration even though they are well-sealed (such as ether, carbon disulfide, tetrahydrofuran, isopropyl ether, etc.). The production date and shelf life should be marked on the labels of these reagents, and the management personnel should conduct regular inspections. There are a wide variety of indicators used in chemical reagents. Generally, solid indicators (except test papers) are not easily deteriorated after long-term storage. In addition, the solutions prepared from some complexometric indicators will undergo polymerization or oxidation reactions after long-term storage. Generally, the phenomenon is the appearance of turbidity or flocculent precipitate, making it difficult to indicate the titration end point sensitively.

[0055] As can be seen from the above, the chemical properties of the reagent itself, the storage environment, whether it is strictly sealed, etc. are all factors that cause the reagent to deteriorate. Therefore, the laboratory management system in this embodiment monitors these factors to analyze the deterioration risk of various reagents and manage the reagents in the laboratory automatically and accurately.

[0056] Specifically, the image acquisition module 11 can identify the appearance information of the reagent, perform sensory intelligent analysis instead of the human eye, and effectively judge whether the form of the reagent has changed, such as discoloration, deliquescence, caking, precipitation, etc.

[0057] The environment monitoring module 12 may include:

[0058] Gas sensors are installed at multiple positions to collect the gas at each detection point and detect whether there are harmful gases, which can judge whether there is leakage of volatile reagents;

[0059] Infrared sensors and temperature sensors monitor the temperature and light around the reagent to facilitate judging whether the reagents sensitive to temperature and light are affected;

[0060] Vibration sensors are installed on the laboratory tabletop and storage area to monitor whether the reagent is vibrated;

[0061] Pressure sensors are installed in the reagent storage area to monitor the quality change of the reagent.

[0062] The management module 13 performs text or label recognition in the reagent image to determine the reagent name, and comprehensively processes the above appearance information and environment information to judge whether the reagent is adversely affected by multiple factors, and makes a qualitative judgment on whether each reagent has a deterioration risk, providing a reference for subsequent reagent use and disposal.

[0063] In the embodiment of the present invention, the appearance information and storage environment information of the reagents in the laboratory are respectively collected through the image acquisition module and the environment monitoring module. Combining with the reagent name, the storage deterioration characteristics of the reagent can be determined. Whether the reagent has significantly deteriorated is judged through the appearance information, and whether the reagent is adversely affected by environmental factors during the storage process is judged, so as to timely and accurately judge the quality of the reagent and improve the reagent management effect.

[0064] In a possible implementation manner, the management module 13 is specifically used for:

[0065] Determine the storage container template, appearance information evaluation interval and environment information evaluation interval of the reagent based on the reagent name;

[0066] Correct the reagent image based on the storage container template to obtain the appearance image of the reagent, and extract the appearance information of the reagent from the appearance image;

[0067] Compare the appearance information with the evaluation range of the appearance information of the reagent to obtain the reagent appearance diagnosis result of the reagent;

[0068] Compare the environmental information with the evaluation range of the environmental information of the reagent to obtain the storage environment diagnosis result of the reagent;

[0069] If both the reagent appearance diagnosis result and the storage environment diagnosis result of the reagent are abnormal, it is determined that the deterioration risk of the reagent is high.

[0070] In this embodiment, chemical drugs must be stored separately according to their chemical properties and scientific storage methods should be adopted. For example, those sensitive to light and liable to deterioration should be packed in light-proof containers, usually brown glass bottles; those volatile and soluble should be sealed; those not used for a long time should be sealed with wax; glass bottles containing alkalis cannot use glass stoppers, etc. Since different types of reagents use different types of storage containers, the container type used for the reagent can be determined according to the reagent name, and the light-transmitting characteristics of the container can be used to process the image to accurately extract the reagent appearance image inside the image.

[0071] For example, the containers can be divided into brown glass bottles, transparent glass bottles, and transparent plastic bottles. For each type of container, images of various items inside and outside the container of this type are collected to form a training set to train the convolutional neural network. Finally, the convolutional neural network corresponding to the category is determined according to the reagent name, and the trained convolutional neural network is used to process the reagent image to extract the reagent appearance image inside the reagent image.

[0072] After obtaining the reagent appearance image, the appearance characteristics of the reagent, such as color, texture, shape, etc., can be extracted from the appearance image and compared with the evaluation range of the appearance information corresponding to the reagent to determine whether the reagent is actually deteriorated in appearance. For example, sodium hydroxide is liable to absorb water vapor in the air and deliquesce and deteriorate with carbon dioxide, changing from crystals to powder, mercury dichloride (HgCl2), silver nitrate (AgNO3) solution shows precipitation, stannous chloride (SnCl2) solution shows white precipitation and ferrous sulfate (FeSO4) solution turns brown, etc. These phenomena can determine that the reagent has deteriorated.

[0073] The sealing, light exposure, moisture absorption, temperature rise, etc. of the reagent may all cause the reagent to deteriorate. Monitoring the light, temperature, humidity, and sealing conditions of the reagent storage environment can also determine whether the reagent may deteriorate due to environmental impacts. The evaluation range of the environmental information of the reagent can be determined according to the storage environment required by the reagent. If it is monitored that a certain reagent sensitive to light decomposition has the light intensity and duration exceeding the light intensity and duration in the environmental information evaluation range during the historical period, it is determined that the storage environment diagnosis result is abnormal. The judgment of conditions such as temperature, humidity, and vibration is the same.

[0074] The reagent appearance diagnosis results and storage environment diagnosis results of the reagent can be used as judgment indicators of reagent deterioration in different aspects. When both are abnormal, it can be determined that the risk of reagent deterioration is high, which can prompt the staff to further verify and deal with it.

[0075] If the reagent appearance diagnosis result of the reagent is abnormal but the storage environment diagnosis result is normal, the reagent may be deteriorated due to other factors; if the reagent appearance diagnosis result of the reagent is normal but the storage environment diagnosis result is abnormal, the reagent may have deteriorated but has not yet been reflected in the appearance. The staff still needs to further confirm the specific situation of the reagent and adjust the storage environment.

[0076] In a possible implementation, the appearance information includes a shape; and the management module 13 is specifically configured to:

[0077] If the reagent is a block reagent, edge detection and connected domain analysis are performed on the appearance image. If there are blocks in the appearance image, whether they are damp and sticky is determined based on the distance between the blocks. If there are no blocks in the appearance image, it is determined that the reagent has changed from a block to a powder or liquid.

[0078] If the reagent is a powdered reagent, edge detection and connected domain analysis are performed on the appearance image. If there are lumps in the appearance image, it is determined that the reagent is agglomerated.

[0079] In this embodiment, edge detection can identify lines in the image, and connected domain analysis can identify closed areas in the image, thereby determining whether there are blocks or cracks in the image. The distance between the edges of each block can be used as the distance between blocks. If the distance between blocks is close to 0, moisture adhesion may have occurred. Whether the block is cracked can also be determined based on whether there are cracks in the block.

[0080] In a possible implementation, the appearance information further includes color distribution; and the management module 13 is specifically configured to:

[0081] If the reagent is a liquid reagent, the RGB values ​​of multiple positions in the appearance image are compared to determine whether there is a precipitate in the reagent.

[0082] In this embodiment, when the liquid reagent has a uniform texture, the colors of the various parts in the appearance image are similar, and the RGB values ​​should also be similar. If there is a precipitate, there may be multiple pixels with RGB values ​​of A and multiple pixels with RGB values ​​of B, that is, there are at least two colors with large differences in the appearance image. If the precipitate has been generated for a long time, there may also be obvious color partitions in the upper and lower parts of the appearance image.

[0083] In a possible implementation, the environment monitoring module 12 includes a weighing unit, which is arranged below the reagent;

[0084] The management module 13 is also used to determine whether the mass of the reagent has changed based on the weighing data collected by the weighing unit at multiple times.

[0085] In this embodiment, the weighing unit may be a pressure sensor, and the weighing data, i.e., the weight of the reagent, is determined by the pressure generated when the reagent is placed above the pressure sensor. For gas reagents, the weight of the gas cylinder storing the gas may be monitored. If the weight of the gas cylinder changes too much, there may be a gas leak or the gas cylinder may be placed in the wrong position.

[0086] In one possible implementation, the environment monitoring module 12 includes a vibration sensor;

[0087] The management module 13 is also used to determine the vibration intensity to which the reagent is subjected based on the placement position of the vibration sensor and the collected vibration signal.

[0088] In this embodiment, concentrated sulfuric acid, hydrofluoric acid, liquid chlorine, liquid bromine and other substances. Such substances should be handled with care, and collision, drop and strong vibration are strictly prohibited. Multiple vibration sensors can be used to determine the source location and vibration intensity of the vibration signal, and the vibration intensity transmitted to the reagent placement can be calculated in combination with the vibration conduction characteristics of the laboratory environment.

[0089] In a possible implementation, the management module 13 is further configured to:

[0090] Extract the shelf life of the reagent in the reagent image and determine the remaining shelf life of the reagent;

[0091] The remaining shelf life is adjusted based on the reagent status of the reagent to obtain the remaining usage time of the reagent.

[0092] In this embodiment, the labels of the reagents should be marked with the production date and shelf life.

[0093] The deterioration of reagents is a gradual process, and the shelf life is the reference period that the reagent manufacturer promises that the reagent quality will not change. It cannot accurately indicate the specific time when the reagent deteriorates. When it is recognized that the state of the reagent has changed, the remaining shelf life can be adjusted according to the specific degree of the state change, which more accurately indicates the length of time the reagent can continue to be used normally. Specifically, the remaining use time of the reagent can be determined based on the following formula:

[0094] Remaining usage time = Remaining shelf life * Deterioration rate * Remaining shelf life ratio / Opening time ratio Where:

[0095] Deterioration rate = deterioration ratio / opening time

[0096] The deterioration ratio may be the percentage of reduction in the concentration of the active ingredient in the reagent.

[0097] Ratio of remaining shelf life = Remaining shelf life / Total shelf life

[0098] Ratio of opening duration = Opening duration / (Opening duration + Remaining shelf life)

[0099] In a possible implementation, the image acquisition module 11 is further configured to acquire images of personnel in the chemical laboratory;

[0100] The management module 13 is further configured to identify the identity of the personnel and the name of the reagent taken by the personnel in the personnel image. If the deterioration risk of the reagent corresponding to the reagent name is high, the personnel is prompted to confirm the reagent status, and the reagent status is corrected based on the reagent status input by the personnel, and the reagent is managed based on the corrected reagent status.

[0101] In this embodiment, the personnel can input the reagent status by voice. Specifically, for the reagent whose image is misidentified as having a precipitate, "no precipitate" can be input, or for the deteriorated reagent, the specific deterioration situation can be input after detection, such as the reagent volume after volatilization. The laboratory management system can continue to manage based on the corrected reagent status.

[0102] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0103] The following is a method embodiment of the present invention. For the details not described in detail, reference can be made to the corresponding system embodiment above.
