Description

The present invention relates to an automated analyzer.

An automated analyzer in the field of clinical examination is used to measure a specific component concentration from a sample such as blood or urine collected from a patient in a hospital or the like. In such an automatic analyzer, in order to maintain stable measurement performance, it is important to manage the replacement of parts that are thrown away or consumed in each analysis. For example, in order to perform continuous analysis, it is required to manage disposable parts so as not to run out, and in order to maintain analysis accuracy, it is required to manage wear of parts and replace them as appropriate.

As a conventional technique for managing such parts and the like, for example, Patent Document 1 describes a lighting device that irradiates an image pickup position with light, and an image pickup device that captures an image of the image pickup position with the lighting device turned on. In a serum information measurement system including an image processing device that performs image processing captured by the image pickup device and a storage unit, the image processing device is provided with at least one color sample at the image pickup position, and the image processing device provides the illumination. The first step of acquiring the brightness value of the color sample portion in the entire image captured by the image pickup device in the lit state and comparing it with the specified brightness value stored in the storage unit to determine the correctness of the lighting device. For the color sample portion in the entire image, the hue value and / or the saturation value detected by each image element of the image pickup apparatus is acquired and compared with the hue specified value and / or the saturation specified value stored in the storage unit. A second step of determining whether the image pickup device is correct or not, and a serum information measurement system for performing a process including the same are disclosed.

Japanese Unexamined Patent Publication No. 2016-16301

In the above-mentioned prior art, for example, for a lighting device, the replacement time of the lighting device is determined by comparing the brightness value of the color sample portion in the entire image captured by the imaging device with the lighting device turned on with the specified brightness value. is doing. However, since there are multiple possible factors for the parts to reach the end of their life, it is not sufficient to determine the replacement time of the lighting device using only one index, which is the brightness value, as in the above-mentioned conventional technique. For example, in a cylinder used in an automated analyzer, a resin component (seal piece) that prevents pressure leakage inside the cylinder by contacting with a plunger that drives to suck and discharge the object to be dispensed into the connected probe. It is necessary to consider that the life of the seal piece is caused by the wear caused by the plunger and the aged deterioration which is a characteristic of the resin part. Therefore, in the above-mentioned prior art, it is conceivable that the replacement timing of parts cannot be properly managed.

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

In order to achieve the above object, the present invention is an automatic analyzer including an analyzer that analyzes a sample using a reagent and a control device that controls the operation of the analyzer. Part identification information for identifying and identifying a plurality of parts used in an automatic analyzer, and an index used for each replacement determination of the plurality of parts, which are information related to the time of each part and physical quantity. A parts management information aggregation unit that stores parts management information having a current value of a judgment index defined by information and information related to the number of times and a judgment threshold for judgment of replacement of parts using the judgment index. Whether or not the monitoring unit that periodically acquires the information related to the determination index of the component management information and updates the current value and the current value of the determination index updated by the monitoring unit exceeds the determination threshold. If it is determined that the determination threshold has been exceeded, it shall have a determination unit for notifying the user of the replacement of the corresponding component via the notification unit.

Since it is possible to appropriately manage the replacement time of parts in the automatic analyzer, it is possible to suppress the delay by ensuring the continuity of the analysis process and maintain the analysis accuracy.

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

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

In FIG. 1, the automatic analyzer 100 acquires information from the analyzer 110 and controls the analyzer 110 via a communication line 120 and an analyzer 110 including a mechanism such as a probe unit 111 for handling a sample, a reagent, and the like. It is roughly configured from the control device 130 that performs the above. In the present embodiment, the case where the analyzer 110 and the control device 130 constituting the automatic analyzer 100 are separated from each other will be described by way of example, but the present invention is not limited to this, and for example, the same control board may be used. It may be configured to perform the functions of the analyzer 110 and the control device 130.

The analyzer 110 measures the probe unit 111 that dispenses the sample contained in the sample container 122 and the reagent contained in the reagent cassette 112 into the measuring container 113, and the mixed solution (reaction solution) contained in the measuring container 113. It has a measuring unit 121 that performs qualitative and quantitative analysis of the sample. Strictly speaking, the probe unit 111 differs between the one that dispenses the sample contained in the sample container 122 into the measuring container 113 and the one that dispenses the reagent contained in the reagent cassette 112 into the measuring container 113. , Both are represented by the probe unit 111 for the sake of brevity.

The probe unit 111 dispenses the reagent from the reagent cassette 112 installed in the analyzer 110 to the measuring container 113, and is a tubular probe for holding the reagent while immersing one end in the reagent and sucking it. It has a 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 and holding a reagent or the like in the probe 114 via the tube 116 and discharging the filler held in the probe 114 through the tube 116, and in the cylinder 115. The stepping motor 118 that moves the plunger 117 to change the volume inside the cylinder, the pressure applied to the cylinder 115 leaks from between the cylinder 115 and the plunger 117 (the side surface of the plunger 117), or air or the like enters the cylinder 115 from the outside. It is composed of 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, is provided in contact with the cylinder 115 and the plunger 117, and the plunger 117 slides without a gap while in contact with the seal piece 119. Therefore, the pressure applied to the inside of the cylinder 115 is prevented from leaking from the side surface of the plunger 117, and air or the like is prevented from entering from the outside.

In FIG. 2, the control device 130 constitutes a management operation unit 210 for inputting / outputting parts management information necessary for parts management by a user as a functional unit related to parts management of the automatic analysis device 100, and an automatic analysis device 100. The judgment index aggregation unit 230 that stores the judgment index set for each part, the parts management information aggregation unit 220 that aggregates and stores the parts management information related to the judgment index stored in the judgment index aggregation unit 230, and the automatic analysis. The device information storage unit 240 that stores the device information, which is the information related to the device 100, and the parts management information for the parts specified by the operation of the management operation unit 210 among the information constituting the parts management information are edited and set. Information related to the setting unit 201 and the judgment index of the parts management information is periodically acquired from the device information storage unit 240, and the current value of the judgment index of the parts management information stored in the parts management information aggregation unit 220 is updated. A parts replacement determination (part replacement) based on the monitoring unit 202, the notification unit 250 for notifying the user of various information related to the automatic analyzer 100, and the current value of the determination index updated by the monitoring unit 202. (Necessity determination) is performed, and when it is determined that replacement is necessary, the determination unit 203 that notifies the user via the notification unit 250 to replace the corresponding part, and the parts management information by the management operation unit 210. It is provided with a parts management information history storage unit 260 for recording the operation history of the above. Here, the setting unit 201, the monitoring unit 202, and the determination unit 203 constitute the parts management unit 200.

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

The setting unit 201 collectively collects information necessary for component management input by the operation of the management operation unit 210 by the user and information necessary for component management from the determination index stored in the determination index aggregation unit 230. Is created, and the created parts management information is output to the parts management information aggregation unit 220 and stored. Further, the setting unit 201 operates (adds, edits, deletes, resets, etc.) the parts management information stored in the parts management information aggregation unit 220 based on the operation of the management operation unit 210.

The component management information is component identification information for identifying and identifying a plurality of components used in an automated analyzer, and an index used for each replacement determination of the plurality of components, and is information related to the time of each component. , The current value of the determination index defined by the information related to the physical quantity and the information related to the number of times, and the determination threshold value for determining the replacement of parts using the determination index. The monitoring unit 202 periodically acquires the information related to the determination index of the parts management information and updates the current value. The determination unit 203 determines whether or not the replacement of parts is necessary by determining whether or not the current value of the determination index updated by the monitoring unit 202 exceeds the determination threshold value, and the determination unit exceeds the determination threshold value to replace the parts. If it is determined that is necessary, the user is notified of the replacement of the corresponding part via the notification unit 250.

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

In FIG. 3, the parts replacement management screen 300 is for displaying the parts management information stored in the parts management information aggregation unit 220 and for operating the parts management information by the user, and is a display of the management operation unit 210. It is displayed in.

On the parts replacement management screen 300, parts management information is displayed in a list format for each part on the parts management information display unit 301. For example, the first line at the top of the parts management information display unit 301 is the parts management information. The element name 302 is displayed, and the content (information) of each element of each component is displayed below it. Further, a vertical scroll bar 303 and a horizontal scroll bar 304 for operating the display range are provided and entered when the component management information cannot be displayed on the component management information display unit 301 at one time.

Further, at the bottom of the parts replacement management screen 300, an add button 305 for adding the displayed parts management information, an edit button 306 for editing, a delete button 307 for deleting, and a reset for resetting are performed. 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 parts management information includes a parts management number (display name), a parts management number (Item #), a part name (Item Name), a determination index (Factor), and a judgment index (Factor) for each part of the automatic analyzer 100. Elements such as judgment threshold (Period), warning level (Caution Lv.), Initial value, and current value (Cur. Count) are included. For example, the determination index (Factor) is an index for determining the replacement of the relevant part, and the determination threshold value (Period) is the threshold value for determining the necessity of component replacement for the determination index, and the warning level (Caution Lv. ) Is a threshold for warning the exchange at the judgment threshold (notifying the recommendation of replacement) (warning is specified at 100% ratio to the judgment threshold), and the initial value is the initial value of the judgment index. Yes, the current value (Cur. Count) is the current value of the judgment index. Hereinafter, the parts management information will be described only for a part of the elements as necessary, and the description of other elements having the same explanation will be omitted as appropriate.

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

Returning to FIG. 3, when the user wants to manage another part, for example, on the parts replacement management screen 300, the add button 305 is pressed and the parts management information is newly registered in the parts management information aggregation unit 220 realized by the database. do. In the new registration, the user inputs an element for which the operation restriction shown in FIG. 4 is possible (◯). The parts management information registered in the parts management information aggregation unit 220 includes parts management information of different parts having the same part ID and the same part lot number in order to identify the parts mounted on the automatic analyzer 100. It is not possible to register the part management information of different parts. However, the part management information of the part having the same part ID and the part lot number can be recognized and registered as a plurality of management conditions for the same part.

For example, a case where the parts 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 rubbed and worn each time the plunger 117 is operated. Further, when the seal piece 119 has a characteristic of aging deterioration such as, for example, a resin part, tearing occurs due to the aging deterioration. Then, when a gap is generated on the contact surface between the seal piece 119 and the plunger 117 due to these factors, the pressure in the cylinder 115 leaks or air enters from the gap, so that the sample sucked and discharged by the probe unit 111 or the like. Since the amount of reagent changes, it is possible that the accuracy of the analysis results will change.

When newly registering the parts management information of the seal piece 119 having such characteristics, for example, from the replacement of the seal piece 119 on April 1, 2018 to April 1, 2019, one year later. It is assumed that the specifications require replacement due to aged deterioration that occurs during the period, and that replacement is required when the frictional distance with the plunger 117 (that is, the total amount of movement of the plunger 117) reaches 1000 m. At this time, for example, the user selects aged deterioration and the amount of movement of the plunger from the candidates for the determination index presented by pressing the add button 305 on the parts replacement management screen 300 when newly registering the parts management information. Further, as the determination threshold value, 365 days is input for aged deterioration, and 1000 m is input for the plunger movement amount. When managing the same part under a plurality of conditions, the same value is input to the part ID and the part lot number.

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

Further, the current date and time held by the management operation unit 210 is automatically acquired and set as the work date and time of the parts management information. For the worker ID, for example, the login information input for using the management operation unit 210 is used. For the work ID, a value uniquely determined for the operation in the management operation unit 210 is used. For post-processing that exceeds the judgment threshold, make a selection in the input form provided in the form of a check box. In this case (when it is determined that replacement is required), only the analysis requested by the automatic analyzer 100 up to that point is continuously performed, and the analysis requested after it is determined that replacement is required is not performed. To perform the analysis again, the reset button 308 is operated or the edit button 306 is operated to change the determination threshold value.

A set 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 arrival from the fluctuation transition of the judgment index set in the parts management information to the judgment threshold value, and automatically sets the timing to warn the replacement of parts (notify the recommendation of replacement). Is. For example, when the movement amount of the plunger 117 is used as a judgment index, the transition of the movement amount is maintained every day for one month, and the date and time when the judgment threshold is reached is calculated by an approximate formula. The timing for warning the replacement of parts (notifying the recommendation of replacement) shall be one month before that.

When the user has already registered and changes the content of the parts management information stored in the parts management information aggregation unit 220, the parts management displayed in a list format on the parts management information display unit 301 of the parts replacement management screen 300. After selecting the parts management information to be changed from the information, press the edit button 306. As a situation where the parts management information is changed, for example, there is a case where the wrong information is registered, or a case where the parts determination threshold value is changed due to a lot defect. When the edit button 306 of the parts replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 acquires the corresponding parts management information from the parts management information aggregation unit 220, and the user can edit the operation restrictions. Edit the element that has become. When the editing operation is completed, the changed parts management information is overwritten and saved in the parts management information aggregation unit 220.

Further, when the user has already registered and deletes the contents of the parts management information stored in the parts management information aggregation unit 220, the parts displayed in a list format on the parts management information display unit 301 of the parts replacement management screen 300. After selecting the parts management information to be deleted from the management information, press the delete button 307. The situation for deleting parts management information is, for example, when incorrect information is registered, replacement is no longer necessary due to a change in the specifications of parts, or management with the registered judgment index is no longer necessary. and so on. When the delete button 307 of the parts replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 does not accept the user's operation as the operation restriction of the corresponding parts management information cannot be deleted, and the parts The corresponding component management information is deleted from the management information aggregation unit 220.

Further, when the user has already registered and replaces a part whose parts management information is stored in the parts management information aggregation unit 220, the parts displayed in a list format on the parts management information display unit 301 of the parts replacement management screen 300. After selecting the part management information of the replaced part from the management information, press the reset button 308. When multiple parts management information is registered for the same part, select one of them. When the reset button 308 of the parts replacement management screen 300 is pressed in the management operation unit 210, the setting unit 201 acquires the parts management information of the corresponding parts from the parts management information aggregation unit 220 and notifies the user, and the user notifies the user. Make changes to the elements that can reset the operation restrictions of the parts management information. When the reset is executed, the setting unit 201 sets the initial value and the current value of the component management information to the initial value acquired from the determination index aggregation unit 230, and normally sets the component state. Parts in which a plurality of parts management information is registered are searched by the same part ID and part lot in the parts management information aggregation unit 220, and the initial value and the current value of each are the initial values obtained from the determination index aggregation unit 230. Set the value. Then, the changed parts management information is overwritten and saved in the parts management information aggregation unit 220.

When the parts management information is operated by the management operation unit 210, the old parts management information is stored in the parts management information history storage unit 260. In the parts management information history storage unit 260, for example, parts management information is stored without being overwritten according to a predetermined period or a setting such as a predetermined amount of data. That is, the parts management information stored in the parts management information history storage unit 260 is not, for example, confirmed whether the parts were replaced correctly when a defect caused by the damage of the parts occurred, or an illegal operation was performed. It is used to confirm that.

Further, although not shown, the control device 130 has a function of being able to export or import the parts management information stored in the parts management information aggregation unit 220. By using this function, the user can export arbitrary parts management information stored in the parts management information aggregation unit 220 and import it into another system. This is, for example, a function for passing component management information about the analyzer 110 to another control device when the analyzer 110 of the automatic analyzer 100 is connected to another control device. With this function, even when the analyzer 110 is connected to another control device, the component replacement management can be continued.

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

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

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

In FIG. 6, the control device 130 acquires parts management information from the parts management information aggregation unit 220 (step S100) at regular intervals (for example, every minute), and the determination index aggregation unit 230 from the device information storage unit 240. The device information related to the determination index stored in is acquired (step S110), and the method for 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), and 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 processing related to the current value is terminated. As a determination index using "subtraction" as the update method, for example, there is an elapsed time, and the current value is obtained by subtracting the date and time set as the initial value from the current date and time.

Further, when the determination result in step S130 is NO, it is subsequently determined whether or not the update method acquired in step S120 is "cumulative" (step S140), and when the determination result is YES, it is determined. The value of the device information is added to the current value to obtain the current value (step S141), and the process relating to the current value is terminated. As a judgment index using "cumulative" as the update 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 acquiring the amount (unit: μm / pulse) from the analyzer 110 and calculating the movement amount, it is added to the current value.

If the determination result in step S140 is NO, then it is determined whether or not the update method acquired in step S120 is "specific" (step S150), and if the determination result is YES, it is determined. A dedicated update method individually defined in the component management information is performed, the implementation result is set as the current value (step S151), and the processing related to the current value is terminated. When "specific" is used as the update method, for example, in order to accurately manage the life of the seal piece 119, not one information such as only the elapsed time and only the movement amount but multiple device information such as the reciprocating amount and the temperature are used. There are cases where you want 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 used separately.

If the determination result in step S150 is NO, the value of the device information is set as the current value (step S160), and the process related to the current value is terminated. As a determination index using the information of the device information as the current value, for example, there is one specified as the specification of the automatic analyzer 100 such as the absorbance in the filter lens.

In FIG. 7, after the processing related to the current value shown in FIG. 6 is completed, the determination unit 203 of the control device 130 first acquires 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 designating whether it is determined that exchange is required when the threshold value is exceeded or exchange is required when the threshold value is exceeded.

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

Subsequently, the current value and the warning value are compared based on the determination method, and it is determined whether or not 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 that case, that is, when it is determined that the replacement of the corresponding part is unnecessary, the process is terminated.

If the determination result in step S220 is NO, that is, if it is determined that the current value is outside the warning value and the corresponding component needs to be replaced, is the component status of the component management information normal? It is determined whether or not (step S230). If the determination result in step S230 is YES, the component status of the component management information is set to exceed the warning value (step S231), and the user is notified of the component replacement warning notifying the recommendation of replacement of the corresponding component (step S231). Step S232). As a method of notifying the parts replacement warning, 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 in yellow or the like, and the screen is displayed. The alarm text including the part name, current value, and judgment threshold is displayed above.

Further, when the determination result in step S230 is NO, or when the process of 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 defined determination threshold value (step S240), and when the determination result is NO, that is, when it is determined that the notification of the replacement warning of the corresponding part is unnecessary, the process is performed. To finish.

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

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

In the control device 130, for the parts for which the determination threshold exceeding post-processing is set in the parts management information, the part state of the parts management information stored in the parts management information aggregation unit 220 exceeds the threshold (that is,). If the determination result in step S250 is YES), the analysis process after the analysis currently being executed by the analyzer 110 is completed by the request from the control device 130 is restricted. This makes it possible to prevent problems due to damage to parts.

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

In the prior art, for example, for a lighting device, the replacement time of the lighting device is determined by comparing the brightness value of the color sample portion in the entire image captured by the imaging device with the lighting device turned on with the specified brightness value. ing. However, since there are multiple possible factors for the parts to reach the end of their life, it is not sufficient to determine the replacement time of the lighting device using only one index, the brightness value, as in the conventional technique. It is possible that the replacement time cannot be managed properly.

On the other hand, in the present embodiment, in the automatic analyzer 100 including the analyzer 110 that analyzes the sample using the reagent and the control device 130 that controls the operation of the analyzer 110, the control device 130 is , Part identification information for identifying and identifying a plurality of parts used in the automatic analyzer 100, and an index used for each replacement determination of the plurality of parts, which is information related to the time of each part and physical quantity. With the parts management information aggregation unit 220 that stores the parts management information having the current value of the judgment index defined by the information and the information related to the number of times and the judgment threshold for the replacement judgment of the parts using the judgment index. , The monitoring unit 202 that periodically acquires the information related to the judgment index of the parts management information and updates the current value, and determines whether the current value of the judgment index updated by the monitoring unit 202 exceeds the judgment threshold.
