Description

  The present invention relates to an automatic analyzer that performs qualitative / quantitative analysis of biological samples such as blood and urine, and more particularly to an automatic analyzer having a so-called field protection function that changes data input / output according to the level of the apparatus operator.

  Automatic analyzers that perform qualitative / quantitative analysis of specific components in biological samples such as blood and urine are widely used in large hospitals and laboratories due to their high measurement accuracy, high reproducibility, and high processing capacity per unit time. It is spreading as. The analyzer is basically operated by a full-time clinical laboratory technician, but if it is necessary to analyze the sample urgently at night or on holidays, it may be operated by a nurse or doctor unfamiliar with the operation. The In this case, if a parameter unrelated to the analysis is erroneously input / changed, there is a concern that the subsequent analysis may be adversely affected. Therefore, passwords can be set for each operator or for each operator level, such as operators, service personnel, supervisors, etc., and passwords can be requested from the operator when starting up the device, and operations can be performed according to the entered password. For example, Patent Document 1 discloses an automatic analyzer that adopts a configuration that restricts functions.

JP 2000-9735 A

  In the technique described in Patent Document 1, a method of incorporating in screen units as shown in FIG. 2 is adopted. Screen units to be displayed using a screen configuration storage unit 2-1 that defines input / output fields such as buttons and character display areas to be displayed on the screen, and a status signal 2-2 such as the level of the user using the device and the device status The display processing unit 2-3 performs display processing. In the display process, the protection determination process 2-5 is performed on the status signal for each input / output field, and the result is displayed on the display screen 2-4.

  In such a system, since the protection determination processing 2-5 is incorporated in the processing unit of the operation screen, it is not possible to provide operation protection with a high degree of freedom according to the user's operation.

  That is, in a method in which processing is performed in units of operation screens for field protection, it may not be possible to meet the user's change request when the operation is changed according to the status of the device.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic analyzer that ensures the safety of a user interface that is complicated and diversified by allowing the field protection required by the user to be arbitrarily incorporated, reflecting the state of the apparatus at the time of operation. Is to provide.

  The operation screen of the automatic analyzer is composed of input / output fields such as data input, list display, and graph display. These input / output fields are prepared as operation functions, and a target operation screen is created by combining these operation functions.

  Focusing on the fact that operation functions can generally be classified into displayable / not displayable / non-displayable, etc., and by determining the state of the user level, automatic analyzer, etc. and generating this display parameter, Enable field protection.

  By making it possible to define a protection state for each operation screen for this common field protection, it is possible to incorporate field protection requested by the user.

  According to the present invention, the target field protection can be realized only by setting the protection condition without incorporating the field protection required by the user in units of operation screens.

  Also, by preparing a screen for setting protection conditions, it is possible to realize field protection of the operation screen freely at the user level.

  FIG. 1 shows an embodiment of the present invention. The screen configuration storage unit 1-1 stores input / output field (operation function) combination information for each screen. Also, field protection conditions are defined for each screen in the protection condition storage unit 1-2.

  At the time of executing the screen display process, information on the corresponding screen is extracted from the screen configuration storage unit 1-1 and the protection condition storage unit 1-2.

  The field protection processing unit 1-4 refers to state signals 1-3 such as an operator, an operator level, an input value, and a device state, which are factors for determining the state of the input / output field, and is extracted from the protect condition storage unit 1-2. The field protection condition thus determined is determined, the operation possible (E) / operation impossible (R) / non-display (H) are called, and display parameters for the input / output fields extracted from the screen configuration storage unit 1-1 are generated. In the display processing in the display processing unit 1-5, the state of the input / output field is set according to the display parameter, and the target screen 1-6 is displayed. In this way, the field protection process for determining operation protection can be made common to all screens.

  Further, by defining the priority order and judgment formula of the field protection conditions in the judgment logic storage unit 1-7, it becomes possible to realize complicated field protection. Definitions can be registered in the protection condition storage unit 1-2 and the determination logic storage unit 1-7 on the maintenance screen 1-8.

  FIG. 3 shows a processing flow for generating display parameters for the input / output fields of the screen, operable (E) / not operational (R) / non-display (H). Based on the input / output field 3-1 and the state signal 1-3 extracted from the screen configuration storage unit 1-1, display parameters for each state signal are extracted by the parameter extraction process 3-2 from the protection condition storage unit 1-2. . When the display parameter 3-3 is not uniquely determined only by the field protection condition, the determination process 3-4 is performed. Based on the display parameter 3-3, the final display parameter 3-7 of the part is determined by the priority order 3-5 and the determination formula 3-6 registered in the determination logic storage unit 1-7.

An example of a field protection condition registration screen which is one of the maintenance screens 1-8 is shown in FIG. In this example, display parameters 4-3 for the status signals of each component are registered in a matrix format in which screen input / output fields 4-1 are arranged in the vertical direction and status signals 4-2 are arranged in the horizontal direction. Status signals can be added or deleted according to the operation. Display parameters to be registered include component status, operation possible (E) / operation impossible (R) / non-display (H), as well as true (T) / false (F) / non-target (− ) May be registered. When the display parameter is not uniquely determined only by the field protection condition, the determination logic used for the determination process is registered in the logic selection 4-4.

  Examples of screens for registering determination logic are shown in FIGS. FIG. 5 shows an example of a registration screen for status signal priorities. The status signal 5-1 is registered in the priority order 5-2 in descending order of priority. The display parameter of the input / output field subject to field protection is determined according to the registered priority order.

  An example of a screen for registering a judgment formula is shown in FIG. The number of determination formula definitions 6-1 registers the number of formulas used in the determination formula. The judgment formula 6-2 registers logical symbols 6-3, values A and B 6-4, definition contents 6-5, and conditions 6-6 in a matrix. In the logic symbol 6-3, a true / false determination method is registered for the values A and B 6-4. Similar to general logical operations, AND (&&), OR (||), NOT (!), True (TRUE), and false (FALSE) can be registered. The values A and B 6-4 are determined to be true when the display parameters for the state signal registered in the definition content 6-5 match the conditions 1 to 5-6-6. Further, the determination formula 6-2 is determined as AND. Registration of the judgment formula 6-2 is performed in order from the judgment formula 1 in the order of processing. Display parameters for the result of the judgment formula are registered in judgment result 6-7.
