Description

  The present invention relates to an automatic analyzer that performs qualitative and quantitative analysis of biological samples such as blood and urine, and more particularly to an automatic analyzer that has a function of monitoring the analysis state of a specimen (sample).

  The automatic analyzer measures the concentration or presence of a target component in a biological sample such as blood or urine. Compared to measurement by laboratory technicians, analysis speed and analysis accuracy (reproducibility) are higher than those measured by laboratory technicians. Since a general automatic analyzer can analyze a large number of samples in parallel, a large amount of samples can be analyzed in a short time. In that case, it is convenient if it is possible to know (or predict) when the analysis of a specific specimen is finished. As a technique for achieving such an object, Patent Document 1 divides the analysis process into a plurality of sections, stores the average required time of each section, and analyzes the information using the average required time. A technique for predicting the end time (result report time) is disclosed.

JP 2003-279582 A

  The technique described in Patent Literature 1 predicts the analysis end time (analysis result report time) for all samples based on information on the past processing average time for each section (event). However, usually, the operator does not want to know the report time of the analysis result for all analysis results, and in general, the operator wants to know the report time for the sample that wants to know the analysis result in a hurry. In the technique described in Patent Document 1, the report time of analysis results is calculated for all samples and displayed in a table format. In this display, when the result report time of the sample you are interested in is You cannot know at a glance. In addition, calculating the reporting time of the results for all the samples can be a burden on the computer, and there is a concern that other analysis processes may be adversely affected.

  An object of the present invention is to provide an automatic analyzer equipped with a user interface that makes it easy to understand the analysis status of a sample whose report time is desired.

  The configuration of the present invention for achieving the above object is as follows.

An emergency sample monitor display button that is always displayed on the operation screen during operation,
By operating the emergency sample monitor display button, a control means for displaying a list of identification numbers of samples designated as emergency samples and the analysis status of the emergency samples on the operation screen;
Automatic analyzer equipped with.

  Since the guideline of the analysis end time of the urgent sample is known, there is an advantage that the analysis waiting time can be notified to the patient or doctor, and the patient diagnosis can be efficiently scheduled.

  Hereinafter, the present invention will be described in detail with reference to examples.

  FIG. 1 is a schematic configuration diagram of an embodiment of an automatic analyzer according to the present invention.

  In FIG. 1, the automatic analyzer includes a control unit, a storage unit, an analysis unit, and a stirring unit.

  The control unit 115 controls the operation of each unit by an electronic circuit or a storage device that performs detailed operation control of each unit.

The storage unit is composed of a sample storage unit containing the sample container 110 and a reagent storage unit (reagent disk: 103) containing the reagent container 113.

  The analysis unit transmits light from the light source to the reaction between the sample and the reagent in the reaction container 112 of the analysis unit, and performs composition analysis with the spectroscope 107.

  The agitation unit 106 agitates the sample discharged from the sample storage unit into the reaction vessel 112 and the reagent discharged from the reagent storage unit 103 into the reaction vessel 112 using ultrasonic waves generated by a piezoelectric element.

  The reaction vessel 112 in the stirring unit 106 and the analysis unit is immersed in a heat retaining medium typified by water accumulated in the reaction tank, and is maintained at a constant temperature.

  The plurality of reaction vessels 112 are arranged on the reaction disk 104, and are rotated or moved together with the reaction disk 104 by controlling the reaction disk motor by the control unit, so that the space between the stirring unit 106 and the spectroscope 107 is changed. go and come.

  FIG. 2 is a user interface screen display example in the automatic analyzer according to the present invention. An emergency sample monitor button 503 is one of function buttons 502 configured on the operation screen 501. When the user instructs the emergency sample monitor button 503 by an operation such as touching the screen, the emergency sample monitor screen 601 in FIG. 3 is displayed.

  An enlarged view of the emergency sample monitor button 503 is an enlarged view of the emergency sample monitor button 504. The emergency sample monitor button 503 includes a button title 505 and a post-input report time display unit 506. The post-injection report time display unit 506 is a part for easily and easily presenting information on how long an analysis result is output when the user inputs an emergency sample at that time.

  The post-injection report time display unit 506 includes an analysis set name 507 and a post-injection report waiting time 508. The analysis set name 507 is the name of the analysis item configuration set in advance by the user, and the analysis item configuration and analysis set name can be freely edited by the user on the setting screen. The post-injection report waiting time 508 indicates an approximate time until the analysis result is reported in the analysis configuration of the analysis set name 507 when the user inputs an urgent sample at the present time. The post-injection report time display unit 506 allows the user to easily understand how long the analysis result is reported before the emergency sample is input and the user immediately inputs the emergency sample according to the requested analysis item. it can. This makes it possible for the user to use this device to analyze an emergency sample, or to make a decision for selecting whether to analyze with a different device that has a small item but a short time to report the analysis result. .

In addition, by arranging these buttons and displays in places where they are always displayed, such as the function button unit 502, the emergency sample monitor button 503 can be easily and easily switched to the emergency sample monitor screen 601. Thus, it is possible to grasp the reporting time after input, and it is possible to prevent troublesome operations in an emergency.

  For the calculation of the analysis end time, a method similar to the method described in Patent Document 1 can be used. In other words, for each analysis item, an average value of the time required for the analysis for the item in the past is stored, and the average value for all the analysis items assigned to the designated emergency sample is added to obtain the analysis item. is there. In order to calculate the analysis completion time more precisely, it is effective to add the time until the designated emergency sample is actually started to be added to the above average value in each analyzer. Even if it is an urgent sample, the analysis is not always performed by overtaking the normal sample waiting for analysis by each analyzer. By calculating the waiting time for each analyzer, it is possible to improve the accuracy of the expected time of completion of analysis.

  FIG. 3 is a screen display example of the user interface.

In FIG. 3, an emergency sample monitor screen 601 is a screen for showing the analysis status of the emergency sample to the user. The emergency sample monitor screen 601 includes a sample information display unit 603, an information display unit 607 for each analysis item in the selected sample, and the like. The sample information display unit 603 is for displaying information on emergency samples registered in the apparatus, and includes a sample number 604, an analysis status progress bar 613, and a remaining time until all analysis results are reported for each sample. The analysis status progress bar 613 is a bar graph showing how much of the registered analysis items have been analyzed. The bar does not simply expand as the analysis progresses, but the analysis progress bar 613 The display color can be changed to an undispensed display 617, a dispensed display 616, an in-analysis display 615, and an analyzed display 614. This allows the user to visually understand the analysis progress. In addition, in the remaining time 605 until all analysis result reports, an approximate time until all analysis result reports are displayed is displayed.

  Further, the user displays more detailed analysis information of the desired sample in the sample selection frame 606 on the information display unit 607 of each analysis item in the selected sample. The information display section 607 for each analysis item in the selected sample is composed of analysis items 609 and analysis results 610.
