In a related scenario, after the operator of the laboratory has finished the task of the laboratory, the operational flow is registered to form an operational record. Further, data corresponding to the operation flow may be derived from the sample analyzer, and this data may be data reflecting the operation of the sample analyzer under the operation of the operator. However, in this way, the operation process and the instrument running condition are recorded afterwards, and the operator can miss or wrongly write the activity record because of forgetting or other reasons when performing the activity record, so that the activity record cannot truly and accurately restore the previous operation process, which brings inconvenience to the management of the clinical laboratory.
In order to solve the above technical problems, an embodiment of the present application provides a laboratory management system, and its architecture, device composition, and device structure may be as shown in fig. 1 to 3. As shown in fig. 1, in a laboratory scene, the activities of a person in the monitoring field of view of the camera may be recorded in an image by the camera, and the instructions input by the person to the sample analyzer may also be recorded by the sample analyzer. Thus, the sample analyzer may be operated by an operator and record instrument operation related information recording any information related to the operation of the instrument, and the camera device may collect laboratory image data of a laboratory scene in which the sample analyzer is located, which laboratory image data records persons, things and any events occurring in the laboratory scene.
The control device in the laboratory management system may obtain the instrument operation related information from at least one sample analyzer of the laboratory management system, and obtain laboratory image data from a camera device of the laboratory management system, and correlate the instrument operation related information with the laboratory image data to generate a laboratory operation record.
Therefore, the control device of the laboratory management system can respectively acquire the instrument operation related information of the sample analyzer and the laboratory image data acquired by the camera device, and correlate the instrument operation related information with the laboratory image data to form laboratory operation records, so that the laboratory operation records can reflect the personnel activity condition and the instrument operation condition of a laboratory, can provide reference basis for laboratory operation condition tracing for laboratory management personnel, is convenient for laboratory management, does not need to manually record personnel operation processes by operators, can avoid error in recorded operation processes caused by personnel forgetting or wrong memory, can avoid error in laboratory operation records, and further improves the accuracy of laboratory operation records, and is favorable for accurate management of the laboratory.
In a preferred embodiment of the present application, the instrument operation related information of the sample analyzer includes at least one of an operation log and sample detection result related information obtained by detecting the biological sample by the sample analyzer. The operation log comprises at least one of operation state change information, system maintenance matters, parameter setting matters, alarm matters and instrument quality control matters in response to operation instrument instructions of an operator, and the sample detection result related information comprises at least one of item result details, alarm information, quality control out-of-control information and reagent consumable information.
The quality control uncontrolled information refers to uncontrolled result information of the sample analyzer to execute quality control test. Specifically, before the sample analyzer performs the sample test of the patient, the quality control test is required to be performed on the test items of the patient, and the quality control test is performed by placing the quality control product into the placing area of the sample analyzer every day by a user, and after the quality control test is completed, the sample analyzer outputs the quality control product to the recycling area of the sample analyzer for the user to take out. The purpose of the quality control test is to check the state of the corresponding item of the instrument, if the result of the quality control test is abnormal, namely out of control, the current state of the instrument cannot guarantee the accuracy of the test result after the patient sample executes the out of control item test, and the out of control item of the instrument is required to be tested again at this time, for example, whether out of control is confirmed, for example, the quality control item is replaced, for example, the reagent is replaced, and the patient sample cannot be tested until the out of control item is in control again, because the instrument can guarantee the accuracy of the item test result of the patient sample at this time.
Therefore, when the quality control is out of control, the information about the sample detection result recorded by the sample analyzer can include quality control out-of-control information, and the quality control out-of-control information can represent the execution time of the quality control test, the information indicating the operator of the quality control test, the quality control product used, the quality control out-of-control result, and the like, so that the laboratory manager can confirm the condition of the quality control out of control and take proper out-of-control treatment.
The system maintenance items refer to maintenance items performed by a person on the sample analyzer, and may include, for example, daily maintenance items such as sample needle cleaning, reagent needle cleaning, liquid path cleaning, and needle blocking detection. By looking at the system maintenance items, the laboratory manager can learn which maintenance operations the sample analyzer performed, whether system maintenance is in place, and so on.
The laboratory image data collected by the camera device at least comprises personnel activity data and interaction behavior data of operators on instruments.
Therefore, through the instrument operation related information and the laboratory image data, the operation matters of the sample analyzer under the instruction of an operator and the actions of the operator in the laboratory can be acquired, so that the associated record of the instrument operation matters and the personnel activity images can be conveniently formed.
In another preferred implementation manner of the embodiment of the present application, the information related to the operation of the apparatus of the sample analyzer is associated with time, and the laboratory image data collected by the image capturing device includes the time of image capturing, and the information related to the operation of the apparatus may be associated with the passing time of the laboratory image data.
Of course, in addition to the time correlation, the instrument operation related information and the laboratory image data may also be correlated by an event, that is, the instrument operation related information and the laboratory image data correspond to the same event, and then the two may be correlated. For example, the instrument operation related information corresponds to an event that an operator takes a sample to be measured and inputs a sample detection instruction to the sample analyzer, and the laboratory image data also shows the personnel activities of the operator taking the sample to be measured and inputting the sample detection instruction to the sample analyzer, so that it can be determined that the instrument operation related information corresponds to the same event as the laboratory image data, and the two can be correlated to form a laboratory operation record.
Besides the correlation between factors such as time and event, the correlation may be performed according to other factors, as long as the correlated instrument operation related information and the laboratory image data can correspond to the same event, and the correlation mode of the embodiment of the application is not limited.
In one way of time-correlation, the control device is specifically configured to extract at least one instrument operation feature from the instrument operation-related information, extract at least one personnel activity feature from the laboratory image data, determine an associated instrument operation feature and personnel activity feature according to a correlation rule, and record the associated instrument operation feature and personnel activity feature to generate a laboratory operation record.
The instrument operation feature represents any feature of the event of the operation of the sample analyzer, for example, the time of the event, the specific content of the event, the personnel information related to the event, and the like. The personnel activity feature represents any feature related to personnel activity, and may include, for example, personnel information, matters and contents of matters of personnel activity, time/place of personnel activity, and any feature information related to personnel activity such as an operating instrument or a used operating tool.
Several ways of correlating instrument operation related information with laboratory image data based on time will be described below.
The association rule may be a determination that the instrument operation related information is associated with the laboratory image data at the same point in time and/or time period. Specifically, the instrument operation feature may include a time point and/or a time period of instrument operation, and the personnel activity feature may include a time point and/or a time period of personnel activity, so that the control device determines that the instrument operation feature with the same time point is associated with the personnel activity feature from at least one instrument operation feature and at least one personnel activity feature; or from at least one instrument operational feature and at least one personnel activity feature, determining that the instrument operational feature of the same time period is associated with the personnel activity feature.
For example, assume 15 for the same day: 00 operating personnel input a sample test instruction on the sample analyzer, then the instrument operation related information of the sample analyzer can record that the sample analyzer receives the sample test instruction input by a user at a certain moment, and meanwhile, the camera device collects personnel moving images of the personnel inputting the sample test instruction on the sample analyzer, so that the control device can extract the instrument operation characteristics of the sample analyzer from the instrument operation related information of the sample analyzer, wherein the instrument operation characteristics can comprise the time point and/or the time period of the instrument operation, namely, the instrument operation characteristics represent the current day 15:00 the operator inputs sample test instructions and extracts personnel activity features from laboratory image data, which may include points in time and/or time periods of personnel activity, i.e., personnel activity features represent the day 15:00 the operator operates the sample analyzer and inputs a sample test instruction on the sample analyzer, so that the operation characteristics of the instrument and the activity characteristics of the operator can be determined to be the same in time, association rules are matched, and the relevant information of the operation of the instrument and the laboratory image data corresponding to the operation characteristics of the instrument and the activity characteristics of the operator can be associated to each other to form a laboratory operation record.
Of course, the associated instrument operation related information and laboratory image data may be for the same period of time that occurs, e.g., person on day 15: 00-15: 30 entering sample information on the sample analyzer, the sample analyzer may generate instrument operation related information to record the activities of the person, while the camera device collects image data of the activities of the person, the control device may extract instrument operation features from the instrument operation related information and extract personnel activity features from the laboratory image data, respectively, and the instrument operation features represent the day 15: 00-15: 30 the person performs an operation of entering sample information on the sample analyzer, the person activity feature representing the current day 15: 00-15: 30 the person operates the sample analyzer and inputs sample information on the sample analyzer, so that the operation characteristics of the instrument and the activity characteristics of the person can be determined to be the same in the occurring time period, association rules are matched, and the operation related information of the instrument and the laboratory image data corresponding to the operation characteristics of the instrument and the activity characteristics of the person can be associated with each other to form a laboratory operation record.
Furthermore, the association rule may also be that the point in time when the personnel activity occurs and/or the instrument operation occurring for a set period of time after the period of time is associated with the personnel activity. Specifically, the instrument operation feature may include a time point and/or a time period of instrument operation, the personnel activity feature may include a time point and/or a time period of personnel activity, and the control device further associates the instrument operation feature of the time period set after the time point of the personnel activity feature with the personnel activity feature; or associating an instrument operational characteristic of a set period of time after the period of time of the personnel activity characteristic with the personnel activity characteristic.
Instrument operation matters after personnel activities are generated are related to the personnel activities, so that personnel can conveniently judge whether the previously generated personnel activities can influence the subsequent instrument operation. For example, if a person wipes a sample needle (the sample needle is used for sucking a sample), if the wiping action is not standardized and does not conform to the standard operation, cross contamination may be caused when the sample is sucked, and thus the detection result of the sample may be affected.
Associating the personnel activities with the subsequent instrument operation, wherein one way may be that at least one personnel activity feature in the laboratory image data comprises a first activity feature of personnel wiping the sample needle, at least one instrument operation feature of the instrument operation related information comprises a first instrument operation feature with sample detection result related information, and the control device may associate the first activity feature with the first instrument operation feature of a set time period after a time point of the first activity feature; or associating the first activity feature with a first instrument operational feature for a set period of time after a period of time of the first activity feature.
The time point or the time period of the first activity feature refers to a time point or a time point when the activity of the person corresponding to the first activity feature occurs, that is, a time point or a time period when the person wipes the sample needle.
Therefore, the first activity feature is associated with the first instrument operation feature to form a laboratory operation record, the personnel activity of personnel wiping the sample needle can be associated with the detection of the sample by the sample analyzer, when the detection result of the sample is abnormal, for example, the detection result of the sample is seriously deviated from a normal value, the laboratory operation record can be checked to trace the personnel activity associated with the detection result of the sample, and if laboratory image data shows that the personnel does have an operation which is not standard and not in line with the standard when the personnel wipes the sample needle, the abnormal sample detection result of the time can be determined to be caused by the personnel wiping the sample needle without the standard.
Associating personnel activities with subsequent instrument operations, which may be another way, wherein at least one personnel activity feature in the laboratory image data comprises a second activity feature of personnel replenishment reagent, wherein at least one instrument operation feature of the instrument operation related information comprises a second instrument operation feature with an operation log, wherein the operation log may comprise alarm events, and wherein the control device may determine that the second activity feature is associated with the second instrument operation feature when an alarm event in the second instrument operation feature for a set period of time after a point in time of the second activity feature comprises a reagent uptake anomaly alarm; or determining that the second activity feature is associated with the second instrument operation feature when the alarm event in the second instrument operation feature for a set period of time after the period of time of the second activity feature includes an abnormal reagent draw alarm.
The time point or the time period of the second activity feature refers to the time point or the time point of the occurrence of the personnel activity corresponding to the second activity feature, that is, the time point or the time period of the supplementation of the personnel with the reagent.
The abnormal reagent sucking can be caused by air suction or mixed air of sucked reagent due to insufficient reagent supplementing amount and the like, or the wrong reagent is sucked due to the fact that personnel supplement wrong reagent and the like, or other types of abnormal reagent sucking scenes which do not meet the reagent sucking specification and do not meet the current reagent sucking requirement.
Therefore, by correlating alarm matters of abnormal reagent suction alarm and the operation actions of personnel for reagent supplement, personnel can conveniently trace and check the reasons of abnormal reagent suction. When the reasons of abnormal reagent suction are examined, the personnel activity characteristics related to the abnormal reagent suction event are called, the corresponding laboratory image data are found, and if the laboratory image data show that the operator does have the abnormal and non-standard reagent replenishing behaviors, the abnormal reagent suction can be determined to be caused by the abnormal behaviors of the operator.
The personnel activities may be associated with a subsequent instrument operation, and the at least one personnel activity feature in the laboratory image data may include a third activity feature of personnel taking the biological sample from the sample analyzer and/or the personnel taking the biological sample from the sample analyzer, and the at least one instrument operation feature of the instrument operation related information may include a third instrument operation feature having an operation log. Thus, when the alarm event in the third instrument operational feature for the set period of time after the point in time of the third activity feature includes a sample draw abnormality alarm, the control device determines that the third activity feature is associated with the third instrument operational feature; or determining that the third activity feature is associated with the third instrument operation feature when the alarm event in the third instrument operation feature for the set period of time after the period of time of the third activity feature includes a sample draw abnormality alarm.
The time point or the time period of the third activity feature refers to a time point or a time point when the activity of the person corresponding to the third activity feature occurs, that is, a time point or a time period when the person takes the biological sample on the machine and/or the person takes the biological sample from the sample analyzer.
The abnormal sample suction may be that the sample cannot be sucked due to the fact that a person places the sample at an incorrect position or the person does not place the sample normally, or that the sample analyzer cannot suck the sample due to the fact that the person recovers the sample to be sucked, that is, a certain sample can be recovered and removed after detection, but an operator removes another sample waiting for sample suction and detection.
Therefore, the personnel can conveniently check and trace the reasons of the abnormal sample suction by associating the activities of the personnel taking the samples from the sample analyzer or the activities of the personnel taking the samples from the sample analyzer with the abnormal sample suction event of the sample analyzer. When the reasons of abnormal sample suction are examined, the related personnel activity features can be traced, laboratory image data corresponding to the personnel activity features can be found, and if the laboratory image data show that an operator does not operate normally when the sample is on-line (such as the sample is placed at an incorrect position or the sample is placed in an incorrect manner), or show that the operator takes the sample waiting for sample suction and detection when the sample is recovered, the abnormal sample suction event at the time can be determined to be caused by the incorrect sample loading or the incorrect sample sampling of the operator.
Therefore, through the association of the abnormal scenes of the instrument operation and the personnel activities, personnel can conveniently check out the occurrence reasons of the instrument operation abnormality, provide the basis and the reference for correcting errors, and improve the laboratory management level.
In other embodiments, when an abnormal feature of an abnormal instrument operation exists in at least one instrument operation feature of the instrument operation related information, the control device may search for a personnel activity feature that causes the abnormal feature to be generated in a time point of the abnormal feature or a preset time period before and after the time period, and associate the abnormal feature with the personnel activity feature that causes the abnormal feature to be generated.
The personnel can preset personnel activity features related to various abnormal features, such as personnel activity features related to personnel supplement reagent when the reagent is sucked abnormally, personnel activity features related to personnel wiping sample needles when the sample detection result is abnormally detected, personnel activity features related to personnel sample loading or personnel sampling when the sample suction abnormality is detected abnormally, and therefore the control device can search the personnel activity features related to the abnormal features in a time point of the abnormal features or a preset time period before and after the time period according to the preset association rules of the personnel, and further determine that the personnel activity features related to the abnormal features are causes for the abnormal features. Therefore, the abnormal characteristics of the instrument operation and the personnel activity characteristics are actively related through the control device, so that personnel can conveniently find out the reasons for causing the instrument operation abnormality, the reason tracing of abnormal events is facilitated, the basis and the reference are provided for correcting the instrument operation abnormality, and the laboratory management level is improved.
In some preferred embodiments, the method of associating the instrument operation related information with the laboratory image data according to the time point or the time period of the instrument operation may further include associating the laboratory image data acquired by the image capturing device during the time period when the at least one sample analyzer is not started up with the instrument operation related information closest to the time period when the at least one sample analyzer is not started up. The purpose of this is that when the sample analyzer is not started, the activity and operation of the operator in the laboratory may affect the operation condition of the subsequent sample analyzer when the sample analyzer is started, for example, the operator wipes the sample needle, at this time, the sample analyzer is not started, but the action of wiping the sample needle may still affect the detection process of the sample by the subsequent sample analyzer, so that the laboratory image data collected by the camera device in the period of time when the sample analyzer is not started can be associated with the relevant information of the instrument operation in the period of time when the sample analyzer is closest to the period of time when the sample analyzer is not started, so that the instrument operation condition represented by the relevant information of the instrument operation in the period of time when the time is closest to the period of time when the sample analyzer is not started can be identified whether the instrument operation condition is affected by the activity of the person in the period of time when the sample analyzer is not started.
For example, the sample analyzer does not execute the sample detection task in the night period, is in a shutdown state, an operator executes the operation of wiping the sample needle at night, and then starts to execute the sample detection task in the early morning period, the laboratory image data of the sample needle, which is collected by the night period image pickup device, can be correlated with the instrument operation related information of the sample analyzer for executing the sample detection in the early morning period, and form a laboratory operation record, when the sample detection result in the early morning period is abnormal (such as seriously deviates from a normal value), a laboratory manager can check whether the sample needle wiping operation in the night period is normal or not through the laboratory operation record, and whether the sample needle wiping operation is the reason for causing the abnormality of the sample detection result is the reason, so that the source for causing the abnormality is detected, and the thought and the reference for correcting the abnormality are provided.
In addition to the above scenario, the laboratory image data collected by the image capturing device during the period when the sample analyzer is not started up is associated with the instrument operation related information at a time point or during the period closest to the period when the sample analyzer is not started up, and another scenario may be that the operation log in the instrument operation related information includes instrument quality control matters and/or instrument calibration matters, and the control device associates the instrument quality control matters and/or instrument calibration matters of the sample analyzer started up on the current day with the laboratory image data collected by the image capturing device during the night time period when the sample analyzer is not started up on the previous day.
The instrument quality control item refers to information related to the sample analyzer performing a quality control test, and includes, for example, information of quality control test results, quality control test personnel, and the like.
By instrument calibration, it is meant that the analysis item needs to be calibrated (i.e., scaled) prior to sample analysis to derive the calibration parameters for the item. And (3) introducing a calibrator and a main curve into the sample analyzer before calibration, selecting a calibration item and a reagent, applying for calibration test, and then starting to execute a calibration detection program to detect a light-emitting value of the calibrator, and then adjusting the main curve according to the actually measured light-emitting value of the calibrator to obtain calibration parameters. The instrument calibration items are information about the sample analyzer performing the calibration test, and include, for example, information about the result of the calibration test, the calibration tester, and the like.
Therefore, by associating the quality control matters or calibration matters of the instrument on the same day with the laboratory image data acquired by the imaging device of the night time of the previous day, a laboratory manager can conveniently confirm whether the quality control or calibration of the instrument on the same day is influenced by the personnel activities of the night time of the previous day, if the quality control is out of control or the calibration fails, whether the personnel activities in the associated laboratory image data accord with the specifications and standards of the quality control operation or the calibration operation can be searched, if the laboratory image data show that the personnel activities do not accord with the quality control operation standards or the calibration operation standards, the quality control out of control or the calibration failure on the same day is influenced by the personnel activities of the night time of the previous day, so that the manager can conveniently check out the reasons of the quality control out of control or the calibration failure.
After the laboratory operational record is formed, this laboratory operational record can be used to manage and trace back personnel activities that have occurred. Several scenarios and embodiments for managing and tracking personnel activities based on laboratory operational records will be described below.
In one application scenario of the laboratory operation record, it may be identified from the laboratory operation record whether the personnel activity is an operation of the operator within his authority. Specifically, the personnel activity characteristics and/or instrument operation characteristics in the laboratory operation records comprise personnel identity information of personnel and personnel activities implemented by the personnel of the identity information, the control device determines the activity authority of the personnel with the identity information according to the identity information of the personnel in the laboratory operation records, judges whether the personnel activities corresponding to the identity information in the laboratory operation records are within the range of the activity authority, and if so, determines personnel activity compliance corresponding to the identity information; if not, generating alarm information to prompt the personnel activity violation corresponding to the identity information.
The activity authority of each operator can be preset and input to the control device, so that the control device can judge whether the operator of the personnel activity is in the range of the activity authority according to the activity authority of each operator.
Therefore, by tracing the personnel activities in the laboratory operation records whether the operators perform personnel activities within the range of the activity authority, the manager in the laboratory can conveniently check out the phenomenon that the operators override to perform the operation, and the manager can conveniently warn the operators aiming at the phenomenon to assist the manager in improving the laboratory management level.
In another application scenario of laboratory operational records, a person may use laboratory operational records to query some or all of the person's activities performed by a person. Specifically, a person can input a person activity inquiry command to the control device, the command carries target identity information, and the control device searches the person activity implemented by the person with the target identity information from the laboratory operation record and returns an inquiry result. The target identity information may be information capable of identifying the identity of the person, such as the name of the person, an identity card number, an ID allocated to the operator by a laboratory, and the like.
Therefore, the application scene can facilitate a manager of a laboratory to search for personnel activities implemented by a certain person and analyze historical personnel activities implemented by the person, and is convenient for the manager of the laboratory to manage the personnel activities.
In another application scenario of laboratory operation records, a person may use the laboratory operation records to query instrument operational matters performed by a sample analyzer. Specifically, a person can input an instrument operation query instruction to the control device, the instruction carries the target analyzer identifier, and the control device searches the laboratory operation record for instrument operation related information executed by the sample analyzer identified by the target analyzer and/or personnel activities executed by the person on the sample analyzer identified by the target analyzer, and returns a query result.
The target analyzer identifier may be any field information capable of identifying a unique sample analyzer, for example, may be an instrument identifier allocated to each sample analyzer by a laboratory, or may be an instrument identifier allocated to each sample analyzer shipped by a sample analyzer manufacturer, which is not limited herein.
Therefore, the laboratory operation record supports the user to inquire the instrument operation matters executed by each sample analyzer and the operations executed by personnel on the sample analyzer, so that the manager can conveniently trace and analyze the historical conditions of the instrument operation, and assist the manager in instrument operation management.
In a preferred implementation of the present application, a pre-trained operational record generation model may be used to generate laboratory operational records. Specifically, the control device obtains a pre-trained operation record generation model, the operation record generation model is obtained by training a plurality of groups of training samples through a machine learning algorithm, each group of training samples comprises laboratory image data, instrument operation related information and label information representing the correlation between the laboratory image data and the instrument operation related information, so that the operation record generation model learns the characteristics of the correlated instrument operation related information and the laboratory image data in the model training process, model parameters are adjusted according to the learned characteristics, model training is stopped when the relation between the predicted label information and the label information in the input training samples meets convergence conditions, and the trained operation record generation model is obtained.
The structure of the operation record generation model may be a convolutional neural network model, a Recurrent Neural Network (RNN), a long-short-term memory network (LSTM), a residual network, or other neural network structure, and the structure of the operation record generation model is not limited.
After the operation record generation model is deployed, the laboratory image data and the instrument operation related information may be input to the operation record generation model, so that the operation record generation model identifies whether the laboratory image data and the instrument operation related information are associated, and the laboratory operation record is output when the laboratory image data and the instrument operation related information are associated.
Therefore, the automatic association of the laboratory image data and the instrument operation related information is realized through the operation record generation model, and the laboratory operation record is automatically generated, so that the generation efficiency of the laboratory operation record is improved.
In another application scenario of the laboratory operational record, it may be identified from the laboratory operational record whether the personnel activities meet laboratory management specifications to determine whether the personnel operations are compliant. Specifically, the control device may obtain a predefined laboratory management specification, compare the generated laboratory operation record with the laboratory management specification, and identify an inconsistent operation behavior in the laboratory operation record.
One way of identifying non-compliant operational behavior in a laboratory operational record may be that the laboratory operational record comprises at least one associated record, each associated record comprising associated instrument operational features and personnel activity features, the instrument operational features being extracted from instrument operational related information, the personnel activity features being extracted from laboratory image data, the laboratory management specification comprising at least one activity scenario and standard operational features corresponding to each activity scenario, the standard operational features being used to represent standard-compliant operations performed by personnel in the activity scenario. Therefore, the control device can determine the target activity scene corresponding to each associated record in the laboratory operation records, and determine at least one standard operation characteristic corresponding to the target activity scene in the laboratory management specification, and if the number of personnel activity characteristics in the associated records is less than the number of standard operation characteristics of the target activity scene, which indicates that personnel activity has missed operation, then the personnel activity in the associated records is determined to be not in accordance with the laboratory management specification; if the number of the personnel activity features in the association record is less than the number of the standard operation features of the target activity scene, but the personnel activity features which are not matched with the standard operation features of the target activity scene exist, the personnel activity is indicated to have misoperation, and the personnel activity in the association record can be determined to be not in accordance with the laboratory management specification; if the number of the personnel activity features in the association record is not less than the number of the standard operation features of the target activity scene and any operation feature to be compared is matched with one standard operation feature of the target activity scene, the personnel activity in the association record is determined to accord with the laboratory management specification.
The activity scene may be any scene of personnel activity, for example, a wiping sample needle scene, a sample analyzer pipeline flushing scene, a sample testing scene, a system maintenance scene, and the like.
For example, laboratory management regulations describe that the normal operation of a person wiping a sample needle is to wipe the sample needle in a top-down direction in order to ensure that the residue of the sample needle mouth is not carried over to the needle cannula so that the residue of the needle cannula is not mixed into the sample the next time the sample is aspirated. And a certain associated record in the laboratory operation records that the personnel activity characteristic is that a certain operator wipes the sample needle from bottom to top, the control device can determine that the personnel activity characteristic of the associated record is not matched with the standard operation characteristic of the target activity scene in the laboratory management specification (namely, the operation of wiping the sample needle from top to bottom of the sample needle wiping scene), so as to further determine that the personnel activity in the associated record does not accord with the laboratory management specification.
The laboratory management system of the embodiment of the application can further comprise an output device which is in communication connection with the control device, and the control device can further control the output device to output prompt information when the personnel activity characteristics in the associated records are not matched with the standard operation characteristics of the target activity scene, wherein the prompt information is used for prompting that the personnel activities in the associated records do not accord with the laboratory management specification.
The output device may be a display screen, a voice output device, or the like, as long as the device can output the prompt information, and the manner of outputting the information is not limited to outputting in the form of voice, text, or the like, and is not particularly limited herein.
Therefore, through comparing the associated record with the laboratory management standard, the operation behaviors which are not in accordance with the standard in personnel activities can be identified, whether the operation behaviors of personnel are in compliance or not and correction is made for the operation behaviors which are not in compliance are convenient for a laboratory manager, the accuracy and the standardization degree of personnel operation are improved, and the laboratory management level is improved.
One way to obtain the laboratory management specification may be to train a deep learning model of the laboratory management specification. Specifically, the control device may obtain historical experimental data of the sample analyzer, where each historical experimental data includes a personnel activity feature and experimental result data corresponding to the personnel activity feature, input the historical experimental data into the initial deep learning model to obtain a laboratory management specification prediction result output by the initial deep learning model, and adjust model parameters of the initial deep learning model according to the laboratory management specification prediction result until the laboratory management specification prediction result output by the initial deep learning model meets a preset condition, and stop training to obtain a target deep learning model of the laboratory management specification.
The personnel activity feature refers to feature information of personnel operation, for example, the personnel activity feature may be a wiping frequency of the sample needle once a week, and the corresponding experimental result data may be a cross infection rate corresponding to the wiping of the sample needle once a week.
Therefore, after the target deep learning model is obtained, the laboratory operation records may be input to the target deep learning model, so that the target deep learning model identifies whether the personnel operation behaviors in the laboratory operation records are compliant according to the laboratory management specification obtained by training, and outputs the identification result.
Therefore, whether the personnel operation behaviors in the laboratory operation records are in compliance or not is identified by using the target deep learning model, so that the identification efficiency of whether the personnel operation is in compliance or not can be improved, and the rapid identification of the personnel operation compliance can be realized.
The other obtaining mode of the laboratory management specification may be that the control device obtains historical experimental data of the sample analyzer, each piece of historical experimental data includes a personnel activity feature and experimental result data corresponding to the personnel activity feature, and if experimental result data in the plurality of pieces of historical experimental data meets a preset condition, the laboratory management specification is generated according to the personnel activity feature in the plurality of pieces of historical experimental data.
The preset condition may be that the experimental result data accords with the expectation of laboratory management personnel and the personnel activity feature corresponding to the experimental result data is used as a standard operation feature when the number of the personnel activity features reaches a threshold value. For example, the personal activity features include a sample needle wiping frequency once a week and a sample needle wiping frequency twice a week, the two personal activity features respectively correspond to different cross infection rates, the sample needle wiping frequency twice a week corresponds to a lower cross infection rate, the sample needle wiping frequency meets the expectations of laboratory management staff, and the number of the personal activity features of the sample needle wiping frequency twice a week in the historical experimental data is higher, the sample needle wiping frequency twice a week is determined as a standard operation feature, and a laboratory management specification is generated by using the sample needle wiping frequency twice a week.
In a preferred embodiment, a laboratory management specification is generated according to the personnel activity features in a plurality of historical experimental data, and the specific operation of the laboratory management specification may be that the control device acquires a plurality of historical experimental data of a laboratory institution, the plurality of historical experimental data corresponds to the same personnel activity feature, the number of experimental result data in the plurality of historical experimental data in each result data range is counted respectively, and a gaussian distribution curve is drawn according to the number of experimental result data corresponding to each result data range; the result data range comprises a preset standard result data range, a target probability value occupied by the standard result data range in a Gaussian distribution curve is determined, if the target probability value is not smaller than the preset probability value, experimental result data corresponding to the standard result data range is determined to be standard experimental result data, personnel activity features in historical experimental data where the standard experimental result data are determined to be standard operation features, and laboratory management specifications are formed by the standard operation features and activity scenes corresponding to the standard operation features.
For example, the same personal activity characteristic for a plurality of historical experimental data may be a sample needle wipe frequency once a week, with the resulting data range representing a range of values for cross-infection rates. Assuming that the control device obtains 100 pieces of historical experimental data, the 100 pieces of historical experimental data comprise a plurality of pieces of historical experimental data corresponding to the personnel activity characteristic of the sample needle wiping frequency once a week and a plurality of pieces of historical experimental data corresponding to the personnel activity characteristic of the sample needle wiping frequency twice a week, the number of the cross infection rate of the 100 pieces of historical experimental data in the numerical range of each cross infection rate can be counted respectively, and a gaussian distribution curve is drawn according to the number of the historical experimental data corresponding to the numerical range of the cross infection rate. The standard result data range may be, for example, a standard data range of a cross infection rate preset by a person, in a gaussian distribution curve, a proportion occupied by the standard result data range is determined, if the standard result data range corresponds to a 2σ interval (i.e., a confidence interval) in the gaussian distribution curve, and the probability value is about 95%, the personnel activity feature corresponding to the standard result data range is determined to be a standard operation feature, for example, assuming that historical experimental data in which the standard result data range is located includes a personnel activity feature of a sample needle wiping frequency twice a week, the personnel activity feature is determined to be a standard operation feature, and a laboratory management specification may be formed.
Based on the historical experimental data, the standard operation characteristics of the laboratory management specification are obtained, and the accuracy and the standardization of the standard operation characteristics are verified by the historical experimental data, so that the standard operation method can be used as the personnel operation standard of a laboratory to standardize personnel activities, and the standardization degree of personnel operation is improved.
In another application scenario of the laboratory operation records, the laboratory supervision report may be generated according to the laboratory operation records, i.e. after the laboratory operation records are generated, the laboratory operation records are generated into the laboratory supervision report according to the report content requirements of the report requester. The report requesting party comprises a laboratory manager, a laboratory supervision organization, a laboratory certification organization and the like.
In a preferred embodiment, the report content requirements may include requirements of the report requester for one or more of a quality control test frequency, a calibration test frequency, and a sample processing flow of the laboratory supervisory report. Thus, the control device can look up the content corresponding to the report content requirement from the laboratory operation record and record the content in the laboratory supervision report.
In another preferred implementation of the embodiment of the present application, the laboratory management system may further comprise a display device, which is communicatively connected to the control device. The control device can receive the activity schedule matters in the preset time period, and when the fact that the current time reaches the starting time of the preset time period is detected, the display device is controlled to display the activity schedule matters in the preset time period, and then a laboratory worker can check the activity schedule in the current time period and develop corresponding laboratory operation.
For example, a person can set an activity schedule item of 8:00 to 12:00 a day to the control device, when the activity schedule item reaches 8:00 a day, the control device controls the display device to display the activity schedule item of 8:00 to 12:00 a day, and a laboratory person can know the operation to be executed and the laboratory activity to be carried out currently by looking at the display device, so that the personnel activity of the laboratory can be carried out orderly and planarly.
In another preferred implementation manner of the embodiment of the present application, the control device may be deployed at the cloud, that is, the cloud processing device receives, as the information about the operation of the instrument sent by the sample analyzer and the laboratory image data sent by the camera device. The control device is deployed at the cloud end, so that the data processing capacity of the control device can be greatly expanded, and the data processing efficiency is improved.
The control device may be disposed at the edge of the sample analyzer and the image pickup device as an edge computing node, and the edge disposition of the control device may be that the control device is integrated on the image pickup device or the sample analyzer, or that the control device is disposed in a local area network where the image pickup device and the analyzer are located, or other edge disposition schemes, which are not limited herein. The edge deployment of the control device can rapidly acquire data sent by the sample analyzer and the camera device, is not easy to be influenced by network fluctuation, and ensures the operation stability of the control device.
In order to solve the foregoing technical problem, an embodiment of the present application further provides a sample analyzer, including: the device comprises an information acquisition device, an objective table, a sample detection device and a control device, wherein the information acquisition device is in communication connection with the control device;
The control device is used for controlling the sample detection device to detect the biological sample carried by the object stage and recording the operation related information of the instrument;
The information acquisition device is used for acquiring the behavior information of the operator and sending the behavior information of the operator to the control device;
The control device is also used for correlating the instrument operation related information with the behavior information of the operator to generate a laboratory operation record.
The information acquisition device may be any device capable of performing information acquisition, for example, may be an image capturing device, where the image capturing device captures image data of personnel activities of an operator, and the image data of personnel activities may extract behavior information of the operator.
The specific implementation manner of associating the instrument operation related information with the behavior information of the operator is similar to the specific implementation manner of associating the instrument operation related information with the laboratory image data by the control device in the laboratory management system, and is not repeated herein.
Therefore, the control device of the sample analyzer can respectively acquire the instrument operation related information of the biological sample detected by the sample detection device and the behavior information of the operator collected by the information collection device, and correlate the instrument operation related information with the instrument operation related information to form a laboratory operation record, so that the laboratory operation record can reflect the personnel activity condition and the instrument operation condition of a laboratory, can provide a reference basis for the laboratory operation condition to trace back for a laboratory manager, is convenient for laboratory management, does not need to manually record the personnel operation process by the operator, can avoid error in the recorded operation process due to personnel forgetting or error memory, can avoid error in the laboratory operation record, and further improves the accuracy of the laboratory operation record, and is beneficial to accurate management of the laboratory.
In order to solve the foregoing technical problem, an embodiment of the present application further provides a laboratory management system, including: the device comprises a camera device, at least one sample analyzer and a control device, wherein the camera device and the sample analyzer are both in communication connection with the control device;
