Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sample processing system, and more particularly to a sample processing system suitable for processing a sample such as blood or urine.

[0002]

2. Description of the Related Art As an automatic analyzer for measuring the chemical and / or biological characteristics of a substance contained in a sample derived from a living body such as blood or urine, its processing capacity is 10 / hour.
There are various types, from small ones such as 0 test to large ones such as 10000 tests per hour. Further, there are various variations in the scale of the system and the measurement target in the measuring method and the handling method of the reagent used for the analysis. In such a situation, it is common for facilities that carry out inspections to use various types of devices together depending on the application. In such a situation, especially in a large-scale facility, in order to reduce the human labor to transfer the sample to each device, the sample is transferred to each device with a belt conveyor-like device. In recent years, a sample transport system for transferring and sequentially measuring has been introduced.

In a chemical analysis system for measuring the chemical characteristics of a sample, a single analyzer for arranging the sample and performing the measurement has been generally used, but each of these analyzers has the following structure. It was common to have the function of.

1. Functions related to sample processing status 2. Function to select measurement item of sample 3. Function to display and edit measurement results 4. Function to register and manage equipment such as reagents necessary for the device. Function to calibrate the device 6. Function for quality control 7. Among the functions that manage the system settings and function maintenance operations, one of these is the function related to the processing status of the sample. It is a function to manage and display whether or not the measurement result is obtained for those which have been taken and the transportation itself has been completed. Although such a function is mainly handled as a whole system, when a trouble occurs, it is necessary to obtain information about each device from the viewpoint of pursuing the cause.

The function of selecting the measurement item of the second sample is to select the item to be measured in the general system for each of the erected samples, and in the system including the pretreatment, dilution, dispensing, etc. Pre-processing is also included as processing to be selected. This function is a function of managing the entire system. For such a function, an ID assigned to the sample is used by using a computer system higher than the conventional one.
In some cases, the code was read by the system and collated with the request for the sample ID.

The function of displaying and editing the measurement result of 3 handles the result of processing on the sample as a system, and manages the system as a whole. However, when a failure occurs in some of the devices, it is necessary to select and check the results related to that device, and in such a case, it is considered necessary to select and check the device. Such a function is related to the point of handling the measurement result among the functions of managing the state of the sample mentioned as one function.

The function of registering and managing the equipment such as reagents necessary for the device 4 depends on the system configuration, but from the viewpoint of integrating independent devices, that is, each integrated device is originally independent. From the viewpoint of being completed as a device, it is a function that should be handled depending on the device. However, in the case of processing the same function in parallel by load balancing, etc., a function of checking the state of the entire system is also required.

The function of calibrating the apparatus of 5 depends on the method of selecting the calibration target, but when the operator carries out the work of constructing the standard sample for calibration, a plurality of processing units are collectively operated. Since standard samples are installed in the system, it is necessary for the system to collectively manage standard sample requests. Regarding the handling of data, it is necessary to judge whether or not the system has been calibrated normally, so this should also be managed and displayed collectively. However, when the same item is processed in parallel in a plurality of analyzers for the purpose of load balancing, etc., it is necessary to have a function of identifying each device and verifying a data difference between the devices.

The quality control of 6 is substantially the same as the function related to calibration of 5. Also in this case, when the same item is processed in parallel in a plurality of analyzers for the purpose of load balancing, etc., it is possible to specify each device and to mutually verify the data between the devices.

Regarding the function of managing and performing the system setting and the function maintaining operation of 7, there is a complicated relationship between the part handled as the whole system and the part handled as individual devices.
Here, the biggest problem is that when a trouble occurs in each device constituting the system, the cause can be found and recovered as soon as possible.

As described above, setting and display screens are prepared for each function increase. However,
Due to the nature of measuring a sample related to a living body, the frequency of changing the system setting, that is, the setting information such as the relationship between the analyzer and the measurement item and the measurement condition is extremely low. Therefore, although an actual system that processes a large amount of samples has various functions as the system itself,
In actual measurement, extremely fixed processing is performed. The operator uses a very limited part of all the functions, and has been devised so that the operator can operate it more easily. In particular, in the conventional device, it was important to be able to display or easily print the information about the installation of the reagent used for the analysis, the information about the installation of the sample to be calibrated, and the information about the installation of the sample about the quality control. . In the case of this reagent, calibration, and quality control, the series of order of calibrating the installed reagent and performing quality control of measurement items is basically fixed. As described above, in the automatic analysis system, although the function of the device is extremely complicated, it is possible to operate the automatic analysis system without any particular knowledge of analytical chemistry.

[0012]

Conventionally, in such a system, since the originally independent analyzer was connected by a belt conveyor-like portion for transporting the sample, the device for transporting the sample and The analyzer and pretreatment device, which are physically connected, are connected to each other by using the communication function for information related to sample transfer and measurement results, but each has its own operation part and is, so to speak, independent. It was common to control. In this case, the device and the transport line connecting them are each provided with an operating section,
In managing each state, it was necessary to manage each device individually.

In the system having such a structure, basically, the step of transferring the sample is automated, in which the sample is simply installed in each device and, after the processing in the device is completed, is installed in the device in the next step. Was only. Therefore, the integration of various devices with different analysis targets, sensitivities and operation methods by a belt conveyor has been improved in that the operation method of a plurality of devices is learned and each device is managed by different methods. In other words, it is not sufficient from the viewpoint of reducing the workload and the burden on the operator.

Further, in the case where a function of monitoring the entire sample transport section and each analysis section is provided due to the above problems,
In particular, it was necessary to prepare a device such as the operation terminal, connect to each transport mechanism and the analysis unit based on the system configuration, and create a program. However, even in such a case, it is difficult to integrate the information in the individual analysis units because the information that depends on the analysis device is different for each analysis unit, and it is only possible to integrate the measurement data etc. in an extremely limited state. Is only intended.

An object of the present invention is to provide a sample processing system with excellent operability by an operator.

Another object of the present invention is to provide a sample processing apparatus suitable for reducing the number of operation screens.

By operating the operation unit to select the sample processing unit on the state monitoring screen, information about the selected sample processing unit is displayed on the information display screen. To do.

For example, a reagent that was displayed in red is now displayed in blue.

Steps 609, 610, 610-1 and 6
11 and 612 are for the calibration sample and are substantially the same as steps 604, 605, 606, 607 and 608 for the reagents. Therefore, it suffices to read “reagent” as “calibration sample”. In addition, step 61
3, 614, 615, 616 and 617 are for the quality control sample, and step 604 for the reagent,
605, 606, 607 and 608, respectively. Therefore, it is only necessary to read “reagent” as “quality control sample”.

In the figure, the portion is shown by hatching for simplification. After that, when the portion of colorimetric 1 indicated by the diagonal line is selected (501), the image display shown in FIG. 14 is performed. That is, in place of the display of the operation status list 81 of FIG. 13, information regarding the state corresponding to “colorimetric 1” is displayed in that portion, “sample”, “reagent”,
It is displayed for each confirmation item of the sample processing unit called "alarm" (502). The confirmation item is not common to all sample processing units. For example, the confirmation items for “colorimetric 2” are the same as those for “colorimetric 1”, but the confirmation items for “input” and “recovery” are “sample” and “alarm”.
The "Sample" in "Input" indicates whether there is a sample, and the "Sample" in "Recovery" indicates whether the sample recovery tray is installed correctly, whether the recovery tray is full, or whether there is any measurement completed. Represents The "alarm" indicates whether or not there is a hardware failure.

Here, a box button 7 called "alarm"

By selecting "alarm" on the right side of "reagent" in FIG. 14 (503), the alarm screen 60 is selected and displayed from the common information screens 52 to 60 (FIG. 7). In this display, the information corresponding to the currently selected analysis unit (colorimetric 1) is selectively displayed, or the corresponding part (colorimetric 1) is displayed.
The display information is rearranged as a high priority (504, 505, 506).

As described above, by using the common display screen, the operator can operate with a smaller number of screens. With respect to the alarms, all the alarms can be checked without using the status monitoring screen by using the button 71 that is constantly displayed.

As described above, by selecting the display in the process of transition from the status monitoring screen to the information display screen that collectively displays the information of the entire system, the location of the problem can be found more easily. can do.

However, it is not necessary to select all the information from the list, and the reagents relating to each analysis unit may be displayed graphically with good visibility corresponding to the shape according to the apparatus configuration of the analysis unit. In this case, a screen dedicated to the analysis unit concerned may be displayed, which may be different from the screen that is set and managed in a unified manner, but the contents of the list displaying all the information are also updated.

According to the embodiment of the present invention, there is an operation unit common to a plurality of analysis units (sample processing units), and information on a plurality of analysis units is collectively (commonly) used by the operation of this operation unit. Can select and display any of the screens (information display screens) to be handled by the user, and further show each analysis unit in a distinguishable manner and place the analysis unit at a position corresponding to the analysis unit shown. Since you can display the status monitoring screen that shows the status collectively, from the status monitoring screen,
It is possible to selectively indicate the situation regarding the analysis unit based on the information of the screen group that collectively handles the information regarding the plurality of analysis units. Therefore, it is possible to reduce the type of operation screen required and Even in the case of a large sample processing system to which the analysis unit is connected, the desired information of the analysis unit can be easily reached.

Further, the status monitor screen has a status display function in accordance with the operation procedure and in accordance with the work sequence for successively updating the change in the operation status, so that the necessary request information is directly displayed from the display. Or you can print,
Realizes simplification of operation.
