Description

  The present invention relates to an automatic analyzer.

  2. Description of the Related Art An automatic analyzer in the field of clinical testing is used in hospitals and the like to measure the concentration of a specific component from a sample such as blood or urine collected from a patient. In such an automatic analyzer, in order to maintain stable measurement performance, it is important to manage the replacement of disposable or consumable parts for each analysis. For example, in order to perform continuous analysis, it is necessary to manage disposable parts and the like so as not to run out, and to maintain analysis accuracy, it is required to manage consumption of parts and appropriately replace them.

  For example, Patent Literature 1 discloses an illumination device that irradiates light to an imaging position and an imaging device that captures an image at the imaging position while the illumination device is turned on. A serum information measurement system comprising: an image processing device that performs image processing performed by the imaging device; and a storage unit, wherein at least one color sample is provided at the imaging position, and the image processing device controls the illumination.

JP-A-2006-161301

  In the above prior art, for example, for a lighting device, the replacement time of the lighting device is determined by comparing the brightness value of a color sample portion in the entire image captured by the imaging device with the lighting device turned on with a specified brightness value. doing. However, since there are a plurality of factors that can reach the end of the life of the component, it is not sufficient to determine the replacement time of the lighting device based on only one index such as the brightness value as in the above-described related art. For example, for a cylinder used in an automatic analyzer, a resin part (seal piece) that prevents leakage of pressure inside the cylinder by contacting a plunger that is driven to suction and discharge an object to be dispensed into a connected probe. It is necessary to consider that the life of the seal piece is attributable to wear caused by the plunger and to deterioration due to aging which is a characteristic of the resin component. Therefore, in the above-described related art, it is conceivable that the replacement time of components cannot be properly managed.

  The present invention has been made in view of the above, and it is an object of the present invention to provide an automatic analyzer that can appropriately manage the replacement time of parts.

  In order to achieve the above object, the present invention provides an analyzer for analyzing a sample using a reagent, and an automatic analyzer including a controller for controlling the operation of the analyzer, wherein the controller is Component identification information for identifying and identifying a plurality of components used in the automatic analyzer, and an index used for determination of replacement of each of the plurality of components. Information, and a current value of a determination index defined by the information related to the number of times, and a component management information aggregating unit that stores component management information having a determination threshold for component replacement determination using the determination index, A monitoring unit that periodically acquires information related to the determination index of the component management information and updates the current value; and whether a current value of the determination index updated by the monitoring unit exceeds the determination threshold. Judgment, when it is determined that exceeds the determination threshold value is assumed to have a judging unit that notifies the user via the notification unit to replace those parts.

  Since the replacement time of parts in the automatic analyzer can be properly managed, delays can be suppressed by ensuring continuity of analysis processing, and analysis accuracy can be maintained.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram schematically showing an entire configuration of the automatic analyzer according to the present embodiment. FIG. 2 is a functional block diagram showing processing contents of the control device in the automatic analyzer.

  In FIG. 1, an automatic analyzer 100 includes an analyzer 110 having a mechanism such as a probe unit 111 for handling a sample, a reagent, and the like, acquiring information from the analyzer 110 via a communication line 120, and controlling the analyzer 110. And a control device 130 for performing the above. In the present embodiment, the case where the analyzer 110 and the controller 130 constituting the automatic analyzer 100 are provided separately will be described as an example. However, the present invention is not limited thereto. You may comprise so that the function of the analyzer 110 and the control apparatus 130 may be performed.

  The analyzer 110 measures a probe unit 111 for dispensing a sample contained in a sample container 122 or a reagent contained in a reagent cassette 112 to a measurement container 113, and measures a mixed liquid (reaction liquid) contained in the measurement container 113. And a measuring unit 121 for performing qualitative / quantitative analysis of the sample by performing Although the probe unit 111 dispenses a sample contained in the sample container 122 to the measurement container 113 and a device for dispensing the reagent contained in the reagent cassette 112 to the measurement container 113, although strictly different, For simplicity of description, both are represented by the probe unit 111 as a representative.

  The probe unit 111 is for dispensing a reagent from the reagent cassette 112 installed on the analyzer 110 to the measurement container 113, and is a tubular probe for holding the reagent while immersing one end in the reagent and aspirating the reagent. 114, a tube 116 having one end connected to the other end of the probe 114, and a cylinder 115 connected to the other end of the tube 116.

  The cylinder 115 includes a plunger 117 for sucking / holding a reagent or the like in the probe 114 via the tube 116, and discharging the filler held in the probe 114 via the tube 116, and a cylinder 115. A stepping motor 118 that changes the volume in the cylinder by moving the plunger 117; pressure applied to the cylinder 115 leaks from between the cylinder 115 and the plunger 117 (the side of the plunger 117); And a seal piece 119 for preventing the operation.

  The seal piece 119 is for sealing the gap between the cylinder 115 and the plunger 117, and is provided in contact with the cylinder 115 and the plunger 117, and the plunger 117 slides without contact with the seal piece 119 without gap. This prevents the pressure applied to the cylinder 115 from leaking from the side surface of the plunger 117, and prevents air or the like from entering from outside.

  In FIG. 2, a control device 130 includes, as functional units related to component management of the automatic analyzer 100, a management operation unit 210 that allows a user to input and output component management information necessary for component management, and the automatic analyzer 100. A judgment index aggregating unit 230 for storing judgment indices set for each component, a component management information aggregating unit 220 for collecting and storing component management information related to the judgment indices stored in the judgment index aggregating unit 230, A device information storage unit 240 that stores device information that is information relating to the device 100; and edits and sets component management information of components specified by an operation of the management operation unit 210 among information that configures the component management information. A setting unit 201 that performs a process of periodically acquiring information related to the determination index of the component management information from the device information storage unit 240 and storing the information in the component management information aggregating unit 220 The monitoring unit 202 that updates the current value of the judgment index of the management information, the notification unit 250 that notifies the user of various information related to the automatic analyzer 100, and the current value of the judgment index updated by the monitoring unit 202 The determination unit 203 performs a component replacement determination (determination of the necessity of component replacement) based on the notification, and notifies the user via the notification unit 250 that the corresponding component is to be replaced when it is determined that replacement is necessary. And a component management information history storage unit 260 that records the operation history of the management operation unit 210 for the component management information. Here, the setting unit 201, the monitoring unit 202, and the determination unit 203 constitute a component management unit 200.

  The management operation unit 210 has, for example, a display as a display output device and a keyboard as an input device, and the user operates the input device while referring to information displayed on the display output device. Various information can be input and confirmed.

  The setting unit 201 collects information necessary for component management input by a user's operation of the management operation unit 210 and information necessary for component management based on the determination index stored in the determination index aggregation unit 230, and manages the component management information. Is created, and the created component management information is output to the component management information aggregating unit 220 and stored. Further, the setting unit 201 performs an operation (addition, editing, deletion, reset, etc.) of the component management information stored in the component management information aggregating unit 220 based on the operation of the management operation unit 210.

  The component management information is component identification information for identifying and identifying each of a plurality of components used in the automatic analyzer, and an index used for determination of replacement of each of the plurality of components. , The current value of the determination index defined by the information on the physical quantity and the information on the number of times, and a determination threshold value for determining the replacement of the component using the determination index. The monitoring unit 202 periodically acquires information related to the determination index of the component management information and updates the current value. The determining unit 203 determines whether or not the component replacement is necessary by determining whether the current value of the determination index updated by the monitoring unit 202 has exceeded the determination threshold, and determines whether the component replacement is necessary when the determination threshold is exceeded. Is determined to be necessary, the user is notified via the notification unit 250 of the replacement of the corresponding part.

  FIG. 3 is a diagram illustrating an example of a case where the component management information stored in the component management information aggregation unit is displayed on the management operation unit. FIG. 4 is a diagram showing elements constituting the component management information.

  In FIG. 3, a parts replacement management screen 300 displays the parts management information stored in the parts management information aggregating unit 220 and allows the user to operate the parts management information. Etc. are displayed.

  In the parts replacement management screen 300, the parts management information is displayed in the parts management information display unit 301 in the form of a list for each part. For example, the top line of the parts management information display unit 301 displays the parts management information. An element name 302 is displayed, and below that, the content (information) of each element of each component is displayed. Also, a vertical scroll bar 303 and a horizontal scroll bar 304 for operating the display range when the component management information cannot be displayed on the component management information display unit 301 at one time are provided.

  Also, at the bottom of the parts replacement management screen 300, an add button 305 for adding displayed parts management information, an edit button 306 for editing, a delete button 307 for deleting, and a reset for resetting A button 308 is provided. The user operates the parts management information by operating these buttons 305 to 308 on the parts replacement management screen 300.

  As shown in FIG. 4, the component management information includes a component management number (display name), a component management number (Item #), a component name (Item Name), a determination index (Factor), Elements such as a judgment threshold (Period), a warning level (Caution Lv.), An initial value, and a current value (Cur. Count) are included. For example, the judgment index (Factor) is an index for judging the replacement of the part, the judgment threshold (Period) is a threshold for judging the necessity of component replacement for the judgment index, and a warning level (Caution Lv. ) Is a threshold value (warning is specified at a 100% ratio with respect to the determination threshold value) for making a determination that warns replacement (notifies replacement recommendation) at the determination threshold value, and the initial value is the initial value of the determination index. Yes, the current value (Cur. Count) is the current value of the judgment index. Hereinafter, only part of the component management information will be described as needed, and description of other components having the same description will be appropriately omitted.

  In each element of the component management information, whether or not the operation by the management operation unit 210 is possible is set as an operation restriction. For example, a judgment index (Factor) can be added or reset, but editing or deletion can be performed. The operation is disabled, and the determination threshold (Period) can be added, edited, and reset, but cannot be deleted. In addition, all operations of the initial value and the current value (Cur. Count) are disabled.

  Returning to FIG. 3, when the user wants to manage another component, for example, on the component replacement management screen 300, the user presses an add button 305 and newly registers the component management information in the component management information aggregating unit 220 realized by the database. I do. In the new registration, the user inputs an element for which the operation restriction shown in FIG. 4 is permitted (〇). Note that the component management information registered in the component management information aggregating unit 220 includes component management information of different components having the same component ID and component lot numbers having the same component lot number in order to identify the component mounted on the automatic analyzer 100. It is not possible to register component management information of different components. However, the component management information of a component having the same component ID and component lot number is recognized and registered as a plurality of management conditions for the same component.

  For example, a case where component management information of the seal piece 119 is newly registered will be described as an example.

  In the probe unit 111, the contact surface of the seal piece 119 with the plunger 117 is worn by friction each time the plunger 117 operates. Further, when the seal piece 119 has a characteristic of aging such as a resin component, for example, a tear is generated due to aging. When a gap is generated in the contact surface between the seal piece 119 and the plunger 117 due to these factors, the pressure in the cylinder 115 leaks from the gap or air or the like enters, so that the sample sucked and discharged by the probe unit 111 is removed. Since the amount of the reagent changes, the accuracy of the analysis result may change.

  In the case of newly registering the component management information of the seal piece 119 having such characteristics, for example, the seal piece 119 is replaced one year after the exchange on April 1, 2018 until April 1, 2019. It is assumed that replacement is necessary due to aging that has occurred in the meantime, and that the specification requires replacement when the friction distance with the plunger 117 (that is, the total movement amount of the plunger 117) reaches 1000 m. At this time, for example, the user selects the aging deterioration and the plunger movement amount from the candidates of the judgment index presented by pressing the add button 305 on the component replacement management screen 300 when newly registering the component management information. In addition, as the determination threshold, 365 days is input for aged deterioration, and 1000 m is input for the plunger movement amount. When the same part is managed under a plurality of conditions, the same value is input to the part ID and the part lot number.

  The determination index candidates presented on the component replacement management screen 300 are stored in the determination index aggregation unit 230, and are read and displayed on the management operation unit 210 via the setting unit 201. The determination index stored in the determination index aggregation unit 230 includes, for example, information such as a determination index name, a unit of a determination threshold, an initial value, a determination method, an update method, and a component state. When is selected, the corresponding unit is displayed and the initial value is obtained as the initial value of the component management information. For example, in the case of aged deterioration, the unit is day and the initial value is the registration date. For the movement amount of the plunger 117, the unit is m (meter) and the initial value is 0 (zero).

  In addition, the current date and time of the management operation unit 210 is automatically acquired and set as the work date and time of the component management information. As the worker ID, for example, login information input to use the management operation unit 210 is used. As the work ID, a value uniquely determined for the operation on the management operation unit 210 is used. For post-judgment threshold post-processing, make a selection in the input form provided in the check box format.For example, if you check the check box to enable post-judgment threshold post-processing, the replacement threshold for the part will exceed the judgment threshold. In this case (when it is determined that replacement is required), only the analysis that has been requested to the automatic analyzer 100 is continuously performed, and the analysis that has been requested after the determination that replacement is required is not performed. To perform the analysis again, the user operates the reset button 308 or changes the determination threshold by operating the edit button 306.

  A setting value can be set for the warning level of the component management information by the automatic setting function. The automatic setting function is a function that predicts the date and time of reaching the determination threshold from the change transition of the determination index set in the component management information, and automatically sets the timing to warn of component replacement (notify replacement recommendation). It is. For example, when the movement amount of the plunger 117 is used as the determination index, the transition of the movement amount is held every day for one month, and the date and time of reaching the determination threshold is calculated by an approximate expression. The warning of the replacement of parts (notification of replacement recommendation) is one month before that.

  When the user wants to change the content of the component management information already registered and stored in the component management information aggregating unit 220, the component management displayed on the component management information display unit 301 of the component replacement management screen 300 in a list format. After selecting component management information to be changed from the information, an edit button 306 is pressed. Examples of situations in which the component management information is changed include a case where the component management information is registered with wrong information, a case where the component determination threshold value is changed due to a lot defect, and the like. When the edit button 306 of the component replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 acquires the corresponding component management information from the component management information aggregating unit 220, and determines that the user can edit the operation restriction. Perform edit operation on the element that is set. When the editing operation is completed, the changed parts management information is overwritten and stored in the parts management information aggregating unit 220.

  When the user deletes the content of the component management information already registered and stored in the component management information aggregating unit 220, the component displayed in the component management information display unit 301 of the component replacement management screen 300 in a list format. After selecting component management information to be deleted from the management information, a delete button 307 is pressed. Examples of situations in which parts management information is deleted include, for example, cases where incorrect information has been registered, replacement of parts has become unnecessary due to a change in the specification of parts, and management with registered judgment indices becomes unnecessary. and so on. When the delete button 307 of the component replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 does not accept a user operation as it is impossible to delete the operation restriction of the corresponding component management information. The corresponding component management information is deleted from the management information collecting unit 220.

  When the user replaces a component whose component management information is stored in the component management information aggregating unit 220 and has already registered the component, the component displayed in a list format on the component management information display unit 301 of the component replacement management screen 300 is displayed. After selecting the component management information of the replaced component from the management information, a reset button 308 is pressed. If a plurality of parts management information are registered for the same part, one of them is selected. When the reset button 308 of the component replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 acquires the component management information of the corresponding component from the component management information aggregating unit 220 and notifies the user. Changes are made to the elements for which the operation restriction of the component management information can be reset. When the reset is performed, the setting unit 201 sets the initial value acquired from the determination index aggregating unit 230 to the initial value and the current value of the component management information, and sets the component status to normal. A part in which a plurality of parts management information is registered is searched for in the parts management information aggregating unit 220 using the same part ID and part lot, and the initial value and the current value obtained from the determination index aggregating unit 230 are respectively obtained. Set the value. Then, the changed component management information is overwritten and stored in the component management information aggregating unit 220.

  When the management operation unit 210 operates the component management information, the old component management information is stored in the component management information history storage unit 260. In the component management information history storage unit 260, for example, component management information is accumulated without being overwritten in accordance with settings such as a predetermined period or a predetermined data amount. That is, for example, the component management information stored in the component management information history storage unit 260 does not confirm whether component replacement has been correctly performed when a failure due to component damage has occurred, or that an illegal operation has not been performed. Used to confirm that.

  Although not shown, the control device 130 has a function of exporting or importing the component management information stored in the component management information aggregating unit 220. By using this function, the user can export arbitrary component management information stored in the component management information aggregating unit 220 and import it into another system. This is a function for transferring component management information on the analyzer 110 to another controller, for example, when the analyzer 110 of the automatic analyzer 100 is connected to another controller. With this function, component replacement management can be continued even when the analyzer 110 is connected to another control device.

  FIG. 5 is a diagram illustrating an example of a determination index for each component of the automatic analyzer.

  As shown in FIG. 5, in the present embodiment, exchange management can be performed for components other than the seal piece 119 included in the automatic analyzer 100 using the elements of the determination index. For example, the plunger 117 wears in proportion to the amount of movement, similarly to the seal piece 119, and the portion in contact with the liquid is eroded. The pump that draws pure water into the apparatus turns on and off the power as needed, and may be damaged due to the number of switching times and the flow rate. The heat ray cut filter lens used in an optical system or the like deteriorates with the lighting time. In addition, the grease of the movable part other than the parts is consumed by the movable amount and the elapsed time, and as a result, a torque exceeding a design value is applied.

  FIG. 6 is a flowchart showing the processing content related to the current value of the component management in the control device, and FIG. 7 is a flowchart showing the processing content related to the warning.

  6, the control device 130 acquires component management information from the component management information aggregating unit 220 at regular intervals (for example, every one minute) (step S100), and from the device information storage unit 240, the determination index aggregating unit 230. The device information related to the determination index stored in the storage unit is acquired (step S110), and the method of updating the determination index of the component management information is acquired from the determination index aggregation unit 230 (step S120).

  Subsequently, it is determined whether or not the update method acquired in step S120 is “subtraction” (step S130). If the determination result is YES, the value of the device information is subtracted from the initial value of the component management information. The current value is set (step S131), and the process related to the current value ends. As a determination index that uses “subtraction” as the update method, for example, there is an elapsed time, and the current date and time is subtracted from the date and time set as the initial value to obtain the current value.

  If the determination result in step S130 is NO, it is determined whether the update method acquired in step S120 is "accumulated" (step S140). If the determination result is YES, The value of the device information is added to the current value to make the current value (step S141), and the processing related to the current value ends. As a determination index using “accumulation” as the updating method, for example, there is a movement amount of the plunger 117, and the number of pulses (unit: pulse) used for controlling the stepping motor 118 for operating the plunger 117 and the movement per pulse After the amount (unit: μm / pulse) is obtained from the analyzer 110 to calculate the movement amount, the movement amount is added to the current value.

  If the determination result in step S140 is NO, then it is determined whether the update method acquired in step S120 is "specified" (step S150). If the determination result is YES, The dedicated update method individually defined in the component management information is executed, the execution result is set as the current value (step S151), and the processing related to the current value is ended. When “specific” is used as the updating method, for example, in order to accurately manage the life of the seal piece 119, a plurality of pieces of device information such as a reciprocating amount and a temperature are used instead of one information such as only a moving amount only for an elapsed time. There are cases where it is desired to use a judgment index that is obtained by performing four arithmetic operations. The function of performing the calculation may be provided inside the component management unit 200, or a processing unit having the function may be separately used.

  If the result of the determination in step S150 is NO, the value of the device information is set as the current value (step S160), and the processing related to the current value ends. As a determination index for which the information of the apparatus information is used as the current value, for example, there is an index defined as a specification of the automatic analyzer 100 such as the absorbance of a filter lens.

  In FIG. 7, after ending the processing related to the current value shown in FIG. 6, the determination unit 203 of the control device 130 first obtains the determination method defined in the determination index aggregation unit 230 (step S200). The determination method is, for example, information such as an inequality sign for specifying whether to determine that replacement is required when the threshold value is exceeded or to determine that replacement is required when the threshold value is exceeded.

  Subsequently, a threshold (warning value) used for determining a warning is calculated by multiplying the determination threshold stored in the component management information by the 100% ratio of the warning level (step S210). In the present embodiment, two types of notifications are issued: a notification of a warning recommending component replacement and a notification of requesting component replacement.

  Subsequently, the current value and the warning value are compared based on the determination method, and it is determined whether the current value is within the range of the warning value defined by the determination method (step S220), and the determination result is YES. In this case, that is, when it is determined that the replacement of the corresponding part is unnecessary, the processing is terminated.

  If the result of the determination in step S220 is NO, that is, if it is determined that the current value is outside the warning value and the corresponding component requires replacement, it is determined whether the component status of the component management information is normal. It is determined whether it is (step S230). If the determination result in step S230 is YES, the component status of the component management information is set to a value exceeding the warning value (step S231), and a component replacement warning notifying the user of recommendation of replacement of the corresponding component is notified ( Step S232). As a notification method of the part replacement warning, for example, the line background of the corresponding part management information of the part management information displayed in the part management information display unit 301 of the part replacement management screen 300 in a list format is colored yellow or the like. An alarm text including the component name, the current value, and the judgment threshold is displayed above.

  When the determination result in step S230 is NO or when the process in step S232 is completed, the current value and the determination threshold value are subsequently compared based on the determination method, and the current value is determined by the determination method. It is determined whether or not it is within the range of the defined determination threshold (step S240). If the determination result is NO, that is, if it is determined that the notification of the replacement warning of the corresponding part is unnecessary, the processing is performed. To end.

  If the result of the determination in step S240 is YES, that is, if it is determined that the component requires replacement, it is determined whether the component status in the component management information exceeds the warning value (step S250). . If the decision result in the step S250 is YES, the component state of the component management information is set to exceed the threshold value (step S251), and the user is notified that the corresponding component needs to be replaced (step S232), and the process is performed. To end. As a method of notifying that parts need to be replaced, for example, the line background of the corresponding parts management information of the parts management information displayed in a list format on the parts management information display unit 301 of the parts replacement management screen 300 is colored yellow or the like. Then, an alarm text including the component name, the current value, and the determination threshold is displayed on the screen.

  If the result of the determination in step S250 is NO, that is, if it is determined that the component does not require replacement, the process ends.

  Note that the control device 130 determines that the component status of the component management information stored in the component management information aggregating unit 220 is greater than the threshold value for the component for which post-determination threshold excess processing is set in the component management information (ie, If the result of the determination in step S250 is YES), the analysis process after the analysis currently being executed by the analyzer 110 is completed in response to a request from the controller 130. As a result, it is possible to prevent problems due to component damage.

  The operation and effect of this embodiment configured as described above will be described.

  In the prior art, for example, for an illumination device, the replacement time of the illumination device is determined by comparing a brightness value of a color sample portion in an entire image captured by the imaging device with the illumination device turned on with a brightness value. ing. However, since there are a plurality of factors that can reach the end of the life of the component, it is not sufficient to determine the replacement time of the illuminating device based on only one index, that is, the brightness value, as in the above-described related art. It is conceivable that the replacement time cannot be properly managed.

  On the other hand, in the present embodiment, in the automatic analyzer 100 including the analyzer 110 for analyzing a sample using a reagent and the controller 130 for controlling the operation of the analyzer 110, the controller 130 is The component identification information for identifying and identifying a plurality of components used in the automatic analyzer 100, and an index used to determine the replacement of each of the plurality of components.
