Description

  The present invention relates to a specimen test preprocessing system, and more particularly, to a method and a processing system for data obtained by a specimen test preprocessing system.

  In hospitals, examinations of specimens such as blood and urine have been introduced before medical treatment for the purpose of quick diagnosis in the clinic. Therefore, it is necessary to promptly report the test result to the doctor. Therefore, a specimen test pretreatment system that automatically preprocesses specimens such as blood and urine has been introduced in hospitals and examination centers to improve the efficiency of examination.

  The system performs preprocessing when a sample is introduced and automatically transports the sample to the automatic analyzer, but the end time of the preprocessing or the arrival time at the automatic analyzer is not known. By checking the end time of the preprocessing or the arrival time at the automatic analyzer by the examination engineer or doctor, it is possible to improve the patient's medical efficiency and the work efficiency.

  In order to solve this problem, there are methods described in JP-A-7-280815 and JP-A-2002-156380. In the former method, the estimated end time is calculated by calculating the sum of the stay time in each processing module. In addition, when there is a processing module in which the sample is congested, the system can cope with the traffic jam by adding the waiting time until processing.

  However, although the staying time changes in actual operation, the former method uses a fixed value, and thus the predicted time may be different from the actual time. The latter method searches the stored data for the test item of the sample to be searched, the type of rack in which the sample is installed, the day of the test, and the sample that matches the input time zone, and averages the end times of the samples found in the search Is the estimated end time. The latter method can reduce the amount of calculation compared with the former method, but has a drawback that the accuracy of prediction is lowered.

Japanese Patent Laid-Open No. 7-280815 JP 2002-156380 A

  In view of the above problems, an object of the present invention is to provide a sample test pre-processing system and a sample test pre-processing method that improve the prediction accuracy of the expected end time when the sample pre-processing is completed.

  The present invention relates to a sample in which a sample transported according to stop-off information is pre-processed by a processing module in a sample inspection pre-processing system that transports a path extending to a rack loading module, various processing modules, and a rack storage module by a transport line. Based on the processing time and the sample transport time during which the sample is transported on the transport line according to the drop-in information, the estimated end time at which the sample pre-test processing ends is calculated.

According to the present invention, the predicted end time is calculated based on the sample processing time for pre-test processing in the processing module and the sample transport time for transporting the sample, so that the predicted accuracy of the predicted end time is improved.
By predicting the time required from when the sample is searched until the processing is completed, it is possible to reduce the waiting time of the patient and improve the work efficiency of the laboratory technician.

  Examples of the present invention are shown below.

  FIG. 1 is a block diagram of a sample test pretreatment system to which an embodiment of the present invention is applied.

  The specimen test pretreatment system is managed by the operation unit 1 including the external input device 21 and the external output device 22. The sample test preprocessing system includes a rack loading module 2, a processing module, 3, 4, 5, 6, 7, 8 and a rack storage module 9. Each module transmits and receives information via the operation unit 1 and the communication cable 15. The rack in which the sample is mounted is dropped according to the drop-in information defined in the operation unit, and processing is performed by the processing module at the drop-off destination.

  3 is a processing module of a centrifuge, 4 is a processing module of a plugper, 5 is a processing module of a dispenser, 6 is a processing module of a labeling machine, 7 is a processing module of a plugging machine, and 8 is a processing module of a sorter It is. A conveyance line made of a conveyance belt or the like carries the rack by way of a route extending to each module.

  Each processing module arriving at the rack reads the bar code when it arrives and reports it to the operation unit 1. The operation unit 1 stores the time when the report is received, that is, the time when the rack arrives, in the in-system rack information database 35 (hereinafter, the database is abbreviated as DB) via the communication processing unit 31 shown in FIG. Further, when a result report is received from each processing module after the process is completed, the result report time is similarly stored in the in-system rack information DB. At this time, the processing time calculation unit 32 obtains the difference between the time when the report arrived at the rack and the time when the result report was received, and stores the difference in the time accumulation DB 34 as the processing time of the processing module.

  Further, the difference between the time when the result report is received and the time when the report arrived at the next processing module is obtained, and the difference is stored in the time accumulation DB 34 as the transport time between the processing modules. The general input module 10 and the buffer modules 11 and 12 shown in FIG. 2 are similarly stored in the time accumulation DB 34 via the processing time calculation unit 32.

  By repeating the above processing, processing time and transport time data are stored in the time storage DB 34. The accumulated processing time of each processing module and the transport time between the processing modules are averaged and standard deviation calculated by the processing time calculation unit 39, and further statistically processed using them, and each result is stored in the processing time DB 38. To do.

  FIG. 6 is a diagram for explaining the outline of an embodiment related to the processing flow of the processing time calculation unit 39.

  The average and standard deviation of each processing time and conveyance time accumulated in the time accumulation DB 34 are obtained (processing 61). Next, data not affected by the stop of the processing module is extracted from each accumulated data (processing 62), and an average and standard deviation thereof are obtained (processing 63). Then, a predicted minimum value and a predicted maximum value of each processing time or transport time are calculated from the average and standard deviation (processing 64 and 65) and stored in the processing time DB 38 (processing 66).

  FIG. 4 shows an example of a screen for outputting and displaying the specimen search and the estimated end time.

  A user inputs a target sample number in the sample number input area 41 for a rack in the sample test pre-processing system that has not been processed, and selects a search button 42 to select a sample to be searched. The estimated time until the number is processed can be known. In addition, by selecting the input sample search button, the end time of the sample to be input can be predicted.

  Here, the term “end of processing” means that all the specimens stop by the processing module to stop by and are stored in the storage module 9 or reach the analyzer 13 or the analyzer 14. Analysis is automatically performed on the sample that has arrived at the analyzer 13 or the analyzer 14, and an analysis result can be obtained. The time taken for analysis by the analyzer 13 or 14 is in the fixed value DB 36, and the test is completed by taking out the fixed time corresponding to the test item of each specimen and adding it to the predicted time when the preprocessing is completed. Time to do.

  The used variable selection button 47 is a button for selecting a variable to be used for calculating the predicted end time. In the case of a fixed value, the value before accumulating the actual result is used, and in the case of the actual measured value, the accumulated actual result is used. Use the value calculated based on. The variable correction selection button 49 is a button for selecting whether or not to use a value corrected with respect to the value selected by the use variable selection button 47. When correction is performed, the corrected value is used. When there is no correction, a value without correction is used.

  The search time display area 43, the current position display area 44, and the estimated end time display areas 45 and 46 are areas for displaying the results of predicting the end time. The search time, the current position of the specimen at the time of search, and the estimated end time, respectively. Displays the shortest and the longest predicted end time.

  FIG. 7 is a diagram for explaining an embodiment relating to a processing flow for predicting the end time of a sample in the system.

  The user inputs a target sample number in the sample number input area 41 and selects the search button 42. At this time, the end time calculation unit 33 in FIG. 3 searches whether the input sample number is in the in-system rack information DB 35 (process 71).

  Further, the current position of the target sample is specified from the in-system rack information DB 35 (process 72), and the current position and the search time are output to the search time display area 43 (process 73). Further, a processing module that stops by the end of the processing is searched (processing 74), and is divided into a transport time between processing modules and a processing time of the processing module (processing 75), and each subdivided time is obtained (processing 76). Thus, by subdividing the time, it is easy to calculate the time required to complete the process.

  The sum of the subdivided times for which initial values have been input in advance is calculated as the required time until the end of the process (process 77), and the range of the estimated required time at which the pre-processing is completed is shown in the end predicted time display areas 45 and 46. (Process 78). At this time, the variable used for the subdivided time is determined by the use variable selection button 47, and the user can select the button. When the selection of the use variable selection button 47 is a fixed value, the value used for the calculation is extracted from the fixed value DB 36, and when the selection is the actual measurement value, the value used for the calculation is extracted from the processing time DB 38.

  If the variable correction selection button 39 is a fixed value, the value before error correction is taken out from the processing time DB 38 or the fixed value DB 36. If the selection is a correction value, the value after error correction is taken. Shall be taken out. When there is a processing module in which the sample is congested, the time for all of the congested samples to end the processing of the processing module is added. As a result, the end time can be predicted even if a traffic jam occurs in the system. Multiple system configurations and traffic jams can be handled.

  When searching for the time required until the processing of the sample to be loaded is completed, the loading sample sample search button 48 is pressed.

  FIG. 8 is a diagram for explaining the outline of an embodiment relating to the processing flow for predicting the end time of the sample to be introduced into the system.

  The search time is output to the search time display area 43, and the current position display area 44 is output as not yet input (process 81). The processing module that stops by the input module 2 before it finishes all the processes is searched (process 82), and the transport time between the processing modules and the processing time of the processing modules are subdivided (process 83). Each time converted is obtained (process 84). After the subdivision, the required time to the process end time is calculated in the same manner as the above procedure (process 85) and output to the predicted end time display areas 45 and 46 (process 86). It is possible to search not only a specific specimen but also all specimens in the system by the same procedure as in FIG.

  FIG. 5 is an example of a screen that displays the estimated end times of all samples in the system.

  By displaying the system status display area 52 and the real-time display area 53 on the system monitor screen 51, the figure of the current position of the specimen and the estimated end time can be known at the same time.

  By displaying the serial number of the sample displayed in the real-time display area 53 on each processing module in the system status display area 52, the current positions of all the samples in the system can be displayed. This makes it possible to provide the current position information of the specimen according to the figure. The real-time display area 53 can always provide the latest information by recalculating the predicted end time every predetermined time and automatically updating it.

  In other words, the user can know the estimated end time of the sample without operating the system monitor screen 51. Further, the output of the result can be not only displayed on the screen but also printed on paper or stored as data, and the user can freely select it.

  When the actual time is out of the predicted time range, the processing time correction unit 37 corrects the difference with respect to the values stored in the processing time DB 38 and the fixed value DB 36. As a result, the difference between the actual time and the predicted time can be reduced as the operation results are accumulated.
