Description

[Technical field]

[0001] SUMMARY OF THE DISCLOSURE The embodiments disclosed herein and in the drawings relate to medical devices and automated analyzers. [Background technology]

[0002] Medical devices are often constructed by combining various structures in a complex manner. For example, an automatic analyzer optically measures the change in color or turbidity caused by the reaction of a mixture of a test sample, such as a test specimen collected from a subject, and a reagent for each test item, for biochemical test items, immunological test items, etc., using a measurement unit 215 such as a spectrophotometer or a nephelometer. This measurement is performed by rotating and translating various arms, mixing various liquids with various other liquids. Then, by optical measurement, test data is generated that indicates the test results represented by the concentration of each test item component in the sample, enzyme activity, etc.

[0003] Since this automatic analyzer operates by combining various components in a complex manner as described above, when an error is suspected to have occurred in the analysis results, it is difficult to determine in which part the error has occurred. For example, an error may occur when a specific number of modules among the various components each perform a specific operation, and finding the cause of such an error is a time-consuming task even for an experienced person.

[0004] More specifically, the measurement accuracy is determined by a combination of multiple performance control factors such as the amount of sample and reagent dispensed into the reaction vessel, and the uniformity and stability of the reagent and standard solution. When an abnormality occurs in the analysis result, it is necessary to identify the causative factor and improve the condition of that factor to improve the abnormality of the measurement result. However, when an abnormality occurs, there are multiple causative factors that the operator must consider, and the time cost of investigating the cause is high. To improve this, it is possible to shorten the time required to investigate the causative factor by extracting and displaying the operating status and event history of the unit used in the measurement in association with the data. In automatic analyzers, whose operations are becoming more complex in order to perform measurements more quickly and efficiently, the effect of these improvement measures is limited.

[0009] Hereinafter, the medical device according to the present embodiment, particularly the medical device provided in the automatic analyzer, will be described with reference to the drawings. In the following description, the aspect ratio of the length, width, and height of each component may be changed for ease of understanding, and the contents of the present disclosure are not limited to those in these drawings or descriptions. Note that the various data handled in this specification are typically digital data. In addition, the processing of these data may be specifically realized by using hardware resources to process information by software, such as by a program stored in a non-transitory storage medium.

[0010] Fig. 1 is a block diagram showing a schematic configuration of an automatic analyzer 1 according to one embodiment. The automatic analyzer 1 includes an analysis unit 2, a drive unit 3, a control unit 4, a data processing unit 5, a system control unit 6, an operation unit 7, a display unit 8, and a measurement operating environment processing unit 9. Fig. 1 is a perspective view mainly showing an example of a specific configuration of the analysis unit 2. The medical device in the present disclosure includes at least a measurement operating environment processing unit 9 that executes processing related to the operating environment from processed data, for example.

[0011] The analysis unit 2 generates blank data by blank measurement, generates standard data by standard measurement that measures a mixture of a standard sample for each test item and a reagent used in the analysis of each test item, and generates test data by test measurement that measures a mixture of a test sample and a reagent. The drive unit 3 drives various constituent units of the analysis unit 2. The control unit 4 controls the drive unit 3. The data processing unit 5 generates analysis data, etc. based on data related to various test items such as blank data, standard data, and test data generated by the analysis unit 2.

[0012] An output section (not shown) equipped with a display section 8 prints the calibration data, analysis data, and the like generated by the data processing section 5 using a printing section, and displays the data on the display section 8.

[0013] The operation unit 7 is an input unit into which a user (operator) inputs instructions and information. Specifically, the user operates the operation unit 7 to input settings for the analysis parameters of each test item, such as the amount of sample dispensed, the amount of reagent dispensed, and the wavelength of the light source. The user also operates the operation unit 7 to input settings for each test item required for testing each test sample.

[0014] The system control unit 6 comprehensively controls the system of the automatic analyzer 1 by integrating the control unit 4, the data processing unit 5, and the output unit.

[0015] A detailed description will be given of an example of the analysis unit 2. The analysis unit 2 includes a sample disk 200, a reagent storage 201, a reagent storage 202, a reaction disk 203, a first reagent dispensing mechanism 204, a second reagent dispensing mechanism 205, a sample dispensing mechanism 206, a first stirring mechanism 207, and a second stirring mechanism 208.

[0016] The sample disk 200 holds a plurality of sample containers 209, and these sample containers 209 contain standard samples, test samples such as serum, etc. The reagent storage 201 is provided with a reagent rack 211 that rotatably holds a plurality of reagent containers 210, and this reagent rack 211 holds the first reagent contained in the reagent containers 210 while keeping it cool. That is, the reagent containers 210 contain, for example, one-reagent and two-reagent first reagents that react with components of test items contained in each sample such as the standard sample and the test sample.

[0017] The reagent storage 202 is provided with a reagent rack 213 that rotatably holds a plurality of reagent containers 212, and this reagent rack 213 holds and cools the second reagent contained in the reagent containers 212. That is, the reagent containers 212 contain the second reagent that forms a pair with the first reagent.

[0018] The reaction disk 203 detachably holds a plurality of holders 216 on a circumference. The holders 216 hold a plurality of reaction vessels 217 in an arc shape at a predetermined interval. In this embodiment, the reaction vessels 217 are held by the holders 216 detachably in the vertical direction. That is, the reaction disk 203 is equipped with a plurality of holders 216 as fixing devices for the plurality of reaction vessels 217, and movably holds the plurality of reaction vessels 217.

[0019] The first reagent dispensing mechanism 204 includes a first reagent dispensing probe, a first reagent dispensing arm, and a washing tank. The first reagent dispensing probe aspirates the first reagent in the reagent container 210 held in the reagent rack 211 and dispenses it into the reaction container 217 from which the sample has been discharged. The first reagent dispensing arm holds the first reagent dispensing probe so that it can rotate and move up and down. The washing tank washes the first reagent dispensing probe every time dispensing of one reagent from the first reagent dispensing probe is completed.

[0020] The second reagent dispensing mechanism 205 includes a second reagent dispensing probe, a second reagent dispensing arm, and a washing tank. The second reagent dispensing probe aspirates the second reagent in the reagent container 212 held in the reagent rack 213 and dispenses it into the reaction container 217 from which the first reagent was dispensed. The second reagent dispensing arm holds the second reagent dispensing probe so that it can rotate and move up and down. The washing tank washes the second reagent dispensing probe every time dispensing of one reagent from the second reagent dispensing probe is completed.

[0021] The sample dispensing mechanism 206 includes a sample dispensing probe, a sample dispensing arm, and a washing tank. The sample dispensing probe aspirates a sample contained in a sample container 209 held on the sample disk 200 and dispenses the sample into a reaction container 217. The sample dispensing arm holds the sample dispensing probe so that it can rotate and move up and down. The washing tank washes the sample dispensing probe every time dispensing of one sample from the sample dispensing probe is completed.

[0022] The first stirring mechanism 207 includes a first stirring bar, a first stirring arm, and a washing tank. The first stirring bar stirs the mixture of the sample and the first reagent dispensed into the reaction vessel 217. The first stirring arm holds the first stirring bar so that it can rotate and move up and down. The washing tank washes the first stirring bar every time stirring of the mixture is completed.

[0023] The second stirring mechanism 208 includes a second stirring bar, a second stirring arm, and a washing tank. The second stirring bar stirs the mixture of the sample, the first reagent, and the second reagent dispensed into the reaction vessel 217. The second stirring arm holds the second stirring bar so that it can rotate and move up and down. The washing tank washes the second stirring bar every time stirring of the mixture is completed.

[0024] The automatic analyzer 1 further includes a reaction vessel cleaning mechanism 214 and a measurement unit 215. The reaction vessel cleaning mechanism 214 performs a cleaning process on the reaction vessel 217 after the test measurement has been completed. Specifically, the reaction vessel cleaning mechanism 214 cleans the reaction vessel 217, dispenses blank water for blank measurement for the next test measurement, and then dries it.

[0025] The measurement unit 215 measures the light that is irradiated onto the reaction vessel 217 that contains a solution such as water or a mixed liquid, and that is transmitted, scattered, or reflected by the reaction vessel 217. The reaction vessel cleaning mechanism 214 performs a cleaning process to clean and dry the inside of the reaction vessel 217 after the measurement of the mixed liquid by the measurement unit 215. In addition, the reaction vessel cleaning mechanism 214 discharges a blank liquid, which is a liquid such as pure water, into the cleaned reaction vessel 217 for blank measurement.

[0026] The measurement unit 215 also generates blank data by blank measurement, which detects light transmitted through the reaction vessel 217 into which a blank liquid has been dispensed. The measurement unit 215 also generates standard data by standard measurement, which detects light transmitted through the mixed liquid in the reaction vessel 217 into which a standard sample and a reagent have been dispensed. Furthermore, the measurement unit 215 generates test data by test measurement, which detects light transmitted through the mixed liquid in the reaction vessel 217 into which a test sample and a reagent have been dispensed.

[0027] The configuration of the automatic analyzer 1 will be described in more detail with reference to FIG. 1. First, the drive unit 3 drives various constituent units in the analysis unit 2 as described above. More specifically, the drive unit 3 rotates the sample disk 200, the reagent rack 211, and the reagent rack 213 individually to move the sample container 209, the reagent container 210, and the reagent container 212, respectively. The drive unit 3 also rotates the reaction disk 203 to move the reaction container 217. Furthermore, the drive unit 3 also vertically and rotates the sample dispensing arm, the first reagent dispensing arm, the second reagent dispensing arm, the first stirring arm, and the second stirring arm individually to move the sample dispensing probe, the first reagent dispensing probe, the second reagent dispensing probe, the first stirring bar, and the second stirring bar, respectively.

[0028] As described above, the control unit 4 controls the drive unit 3 to operate various constituent units of the analysis unit 2. More specifically, in order to perform an examination, the control unit 4 sequentially assigns the test items input from the operation unit 7 for each test sample to the reaction vessels 217 that have been subjected to a cleaning process by the reaction vessel cleaning mechanism 214. Then, the control unit 4 causes the reaction vessel cleaning mechanism 214 to discharge a blank liquid in an amount that is the sum of the dispensed amount of the sample and the dispensed amount of the reagent, which are set as analysis parameters for the test item, to the reaction vessels 217 to which the test items have been assigned. Next, the control unit 215 causes the measurement unit 215 to perform a blank measurement of the reaction vessels 217 into which the blank liquid has been discharged, thereby generating blank data.

[0029] The determination unit determines whether or not the reaction vessel 217 can be used for a test item based on the blank data generated by the measurement unit 215. In this case, since the blank data is collected multiple times, it is determined whether or not the reaction vessel 217 is in a state where it can be used for a test based on the collected multiple blank data.

[0030] If the determining unit 28 determines that the reaction vessel 217 is usable, the analysis control unit 27 dispenses the sample and reagent for the test item assigned to that reaction vessel 217. On the other hand, if the determining unit 28 determines that the reaction vessel 217 is unusable, the analysis control unit 27 stops dispensing the sample and reagent for the test item assigned to that reaction vessel 217. In this case, the analysis control unit 27 further assigns the discontinued test item to the reaction vessel 217 that is to be washed next to the reaction vessel 217 determined by the determining unit 28 to be unusable.

[0031] The data processing unit 5 includes a calculation unit and a data storage unit. More specifically, the calculation unit processes the standard data and test data generated by the measurement unit 215 of the analysis unit 2 to generate calibration data, analysis data, etc. for each test item. The data storage unit stores and holds the collected standard data, test data, etc., and also saves the calibration data, analysis data, etc. generated by the calculation unit.

[0032] The calculation unit generates calibration data for each test item that indicates the relationship between the standard value and the standard data from the standard data generated by the measurement unit 215 and a standard value previously set for the standard sample of the standard data. Then, the generated calibration data is output to the output unit and stored in the data storage unit.

[0033] The calculation unit also reads out calibration data for the test item corresponding to the test data generated by measurement unit 215 from the data storage unit, and generates analytical data represented by concentration values ​​and activity values ​​from the calibration data and the test data. The generated analytical data is then output to the output unit and stored in the data storage unit.

[0034] The data storage unit includes a memory device such as a hard disk, and stores the calibration data generated by the calculation unit for each test item. Also, the data storage unit stores the analysis data for each test item generated by the calculation unit for each test sample.

[0035] The output unit includes a printing unit and a display unit 8. The printing unit prints out the calibration data, analysis data, etc. generated by the calculation unit of the data processing unit 5. That is, the printing unit includes, for example, a printer, and prints the calibration data, analysis data, etc. on printer paper, etc. according to a preset format.

[0036] The display unit 8 includes a monitor such as a CRT (Cathode Ray Tube) or a liquid crystal panel, and displays and outputs calibration data, analysis data, etc. The display unit 8 also displays an analysis parameter setting screen, a test item setting screen, etc., to allow the user to input various information. For example, the analysis parameter setting screen allows the user to input the analysis parameters for each test item, such as the dispensed amount of sample, the dispensed amount of first reagent, or the dispensed amounts of first and second reagents. The test item setting screen allows the user to set the test items set on the analysis parameter setting screen for each test sample.

[0037] As described above, the operation unit 7 is a device for the user to input instructions, information, etc., and includes input devices such as a keyboard, mouse, buttons, and touch panel. The operation unit 7 enables input for setting the dispensing amount of the sample, the dispensing amount of the first reagent, and the dispensing amounts of the first and second reagents as analysis parameters for each test item. The operation unit 7 also performs input for setting information on each test sample to be tested, the test items to be tested for each of the information, etc.

[0038] As described above, the system control unit 6 performs overall control of the automatic analyzer 1. More specifically, the system control unit 6 includes a CPU (Central Processing Unit), a memory circuit, etc., and stores input information such as analysis parameters for each test item and test items input by operation of the operation unit 7 in the memory circuit. Then, based on the stored input information, the system control unit 6 controls the entire automatic analyzer 1 by integrating the control unit 4, judgment unit, data processing unit 5, and output unit.

[0039] The user can check the test results by referring to the results displayed on the display unit 8 or the printed results. If the user determines by referring to these results that an abnormality has occurred in the analysis results, the user may assign an identifier indicating that an error has occurred to the analysis results in which an error has occurred. If the analysis results are shown as numerical values, the measurement operating environment processing unit 9 may extract the data in which an error has occurred based on a threshold value and assign an identifier to it.

[0040] This error occurs as a result of a combination of various factors such as the above-mentioned arms, probes, tanks, tubes through which the liquid passes, or electrical wiring. Furthermore, it may occur due to a combination of how these components are operated and how they are controlled. For this reason, it is not easy to narrow down the cause of this error.

[0041] For this reason, the technology disclosed herein stores the status of the operation of various components and allows the user to access the stored information. By processing the data in this manner, it becomes possible to extract combinations of mechanism operations that may operate non-regularly during analysis.

[0042] The measurement operating environment processing unit 9 stores in the memory unit the analysis results, in association with the results of which mechanism performed which operation. Then, based on this associated data, the measurement operating environment processing unit 9 extracts combinations of mechanisms and operations that may be the cause of errors. The combination of mechanisms and operations may be one operation for one mechanism, or a combination of one operation for each of multiple mechanisms. Moreover, this combination may be a combination of multiple operations for one mechanism, or a combination of one or multiple operations for each of multiple mechanisms.

[0043] The measurement operating environment processing unit 9 may store the operation history itself by linking related operation histories, such as the operating status of an associated mechanism, for each operation. By storing operation histories in this manner, the cause of an abnormality in the analysis result can be estimated as a combination of operations.

[0044] For example, from among the analysis results displayed on the display unit 8, data considered to be normal and data considered to be abnormal are selected, and an identifier indicating normal data and an identifier indicating abnormal data are assigned to each of them. Based on the assigned identifiers, the measurement operating environment processing unit 9 displays measurement operating environment information (information about the combination of the above operations) on the display unit 8. The user may end the processing of the medical device at this point, and determine for himself or herself what the cause is based on the data. Alternatively, the measurement operating environment processing unit 9 may extract and display the combination that is the cause. It is also possible to adopt an embodiment in which the user can specify the results or measurement environment information that he or she wants to compare, and the measurement operating environment processing unit 9 can sort and display the information based on the specification.

[0045] Alternatively, instead of selecting data, the user may classify the data into normal data and abnormal data. In this case, the measurement operating environment processing unit 9 assigns an identifier to each data. The measurement operating environment processing unit 9 may then automatically determine and output information in which a significant difference is recognized between the identifiers.

[0046] In addition, a threshold value may be defined for the discrimination value for the analysis results, and the analysis results shown as numerical values ​​may be automatically judged using this threshold value.

[0047] The combination of the above mechanisms and operations includes, for example, the simultaneous operation state / single operation state of only one side when two or more lines are operated simultaneously, the sampling position, the cleaning line for the inner wall of the probe, the number of operating pulses of the syringe pump, the temperature change due to the injection of constant temperature water, the presence or absence of an interrupt instruction from the operation unit such as a pause instruction during measurement, etc., but is not limited to these. In addition, the output may be made taking into consideration not only the performance viewpoint of the mechanical mechanisms but also the possibility of physical interference with the system. For example, information on possible static electricity may be included.

[0048] Figure 2 is a table showing an example of data in which analysis results and operation history are linked. The two columns on the left show the analysis results, and the column to the right of those shows the operation history. The analysis results record the results for the specimen. For example, this means that a result of 8 was obtained for specimen 01. The operation history records the units (mechanisms) and the operations performed by each unit. For example, this means that for specimen 01, unit X performed an operation of 1, unit Y performed an operation of 1, and unit Z performed an operation of 1. Here, the numerical values ​​for each unit are operations specific to each unit, so the same numerical values ​​do not indicate the same operation.

[0049] The measurement operating environment processing unit 9 associates the result for this specimen with the operation history for the specimen and stores them. Then, processing is performed based on the associated data. For example, if there is a threshold value of 11.5 for the result, and anything below this threshold value is normal, the results of specimens 06 and 08 will contain errors. In such a case, the measurement operating environment processing unit 9 may display the associated data for these results in different colors. For example, as shown in FIG. 2, lines containing errors may be displayed in a different color from normal lines. The display is not limited to colors, and may be easily understood by using shading, bold, italics, or the like.

[0050] Fig. 3 is a table showing another example displayed by the measurement operating environment processing unit 9 on the display unit 8. As shown in Fig. 3, rows containing errors may be sorted, for example, to the top and output. Note that this sorting may be switched to, for example, sorting by unit, etc., by user designation.

[0051] Fig. 4 is a table showing another example displayed by the measurement operating environment processing unit 9 on the display unit 8. As shown in Fig. 4, common items may be automatically extracted for data determined to be erroneous, and displayed in an easily visible and highlighted manner. For example, in the specimen 10, X is also 2 and Y is also 2, but no error is observed. In such a case, possible combinations may be highlighted by further referring to other operation histories.

[0052] In addition, when extracting a combination of actions as shown in Fig. 4, the combination of actions itself may be output instead of the state of the table, for example, "unit X takes action 2, unit Y takes action 2", etc. In this case, the table may be output preliminarily.

[0053] The data displays in FIGS. 2 to 4 are not limited to being used alone, but may be used in combination.

[0054] FIG. 5 is a flowchart showing the process according to this embodiment.

[0055] First, the analysis unit 2 specifies a sample (S100). The analysis unit 2 specifies the sample to be analyzed and executes the analysis operation.

[0056] Next, each unit executes an operation (S102). The operation of each unit indicates various analysis processes as described above. The operation of each unit is executed by the driving unit 3. The driving unit 3 is controlled by the control unit 4. These operations and other operations of the analysis unit 2 may be controlled by the system control unit 6.

[0057] Next, the analysis section 2 stores the operation performed by the unit in the storage section (S104). The operation is stored in association with the designated specimen.

[0058] Next, the analysis unit 2 judges whether all operations have been completed (S106). If all operations related to the measurement have not been completed (S106: NO), the process proceeds to the execution of the next operation. Then, the processes of S102 and S104 are repeated until the operations are completed. One unit is not limited to performing one operation, and one unit may perform multiple operations. In such a case, after one unit has completed its operation, the process proceeds to the operation of the next unit.

[0059] If all operations have been completed (S106: YES), the measurement operating environment processing unit 9 associates the analysis result with the operation history and stores them (S108). Here, the analysis result and the operation history are created as associated data.

[0060] Next, the analysis unit 2 determines whether the measurement and analysis of all the samples are completed (S110). If the analysis of all the samples is not completed (S110: NO), the process from S100 to S108 is repeated. If the analysis of all the samples is completed (S110: YES), the measurement operating environment processing unit 9 processes the operating environment information (S112). In this manner, the above series of processes is executed.

[0061] The timing when the measurement operating environment processing unit 9 links the analysis results with the operation history does not have to be the timing shown in the flowchart. For example, the linking may be performed when storing each operation history, or the analysis results and the operation history may be stored separately, and the linking may be performed for each sample after collecting a predetermined number of samples of data.

[0062] As described above, according to the present embodiment, even when it is difficult to find a correlation by using a medical device that appropriately acquires and processes data, the user can easily find the correlation between the analysis result and the operation history by referring to the operation history categorized by the operation environment. Furthermore, the correlation can be extracted automatically. Furthermore, even when a sudden data failure is encountered, it is possible to rationally and accurately identify the defective part based on the information of the medical device. Therefore, it is possible to reduce time and costs.

[0063] The user may be, for example, a person who performs a test to test a sample. The user at the time of analyzing an error may be a manager who performs maintenance on the device.

[0064] In the above, the object to be stored is one medical device. By analyzing the information of one medical device in this way, it is possible to extract the cause of an error specific to one device, that is, an environment or an individual. However, the technology in the present disclosure is not limited to this. For example, information of multiple identical devices in one medical-related institution (including a testing institution) may be integrated and stored, and errors may be extracted based on this integrated data. In this case, each storage device may be a storage such as a file server provided inside or outside the institution, and data may be aggregated from each device in the storage. Furthermore, information of multiple medical institutions may be acquired and stored in a cloud or the like. In this case, for example, the administrator may obtain permission from the user to upload data by an opt-in or opt-out method. By comprehensively storing and processing data from multiple institutions in this way, it is possible to extract common factors that may cause errors for the same device running in different environments, regardless of the environment.

[0065] The control of the arms to which the sensors and nozzles are connected may be performed by the system control unit 6. That is, the control may be performed by a processing circuit, or the sensors may be controlled via the processing circuit by software processing. This processing circuit may be a CPU as described above, or may be implemented by an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit).

[0066] Although several embodiments have been described above, these embodiments are presented only as examples and are not intended to limit the scope of the invention. The novel device and method described in this specification can be implemented in various other forms. In addition, various omissions, substitutions, and modifications can be made to the forms of the device and method described in this specification without departing from the spirit of the invention. The appended claims and their equivalents are intended to include such forms and modifications that fall within the scope and spirit of the invention. [Explanation of symbols]
