[0037] Below, based on figure 2 This embodiment will be described. figure 2 It is a flowchart explaining the operation control for determining the measurement order of the inspection items according to the present embodiment.

[0038] The flow chart shown in this figure is the analysis from when the user inputs the analysis parameters required for registering the test items to the automatic analyzer 100 via the operation unit 115 in advance, starts the analysis operation after placing the sample and reagent, and ends with the analysis of the sample. Processing flow within the device.

[0039] When the automatic analyzer 100 receives an analysis start instruction from the user, it reads out information (analysis items) assigned to each sample (step S201). An example using a barcode is described here. The information on the item analyzed for the sample is given to the barcode given to the sample, and is read by a barcode reader (not shown). The control unit 116 sends the i...

[0052] In this embodiment, use Figure 4 , Figure 5 A description will be given of an analysis format that can shorten not only the analysis time for all the inspection items requested for a plurality of samples, but also shorten the analysis completion time for each sample.

[0053] Figure 4 It is a flowchart for explaining operation control for determining the measurement order of inspection items in the automatic analyzer according to the present embodiment (second embodiment).

[0054] exist Figure 4 In the flowchart of figure 2 In the flow chart of the above-mentioned part, the description is omitted.

[0055]In the present embodiment, a description will be given of a configuration in which a reaction port for preferentially analyzing a designated test item is provided. Here, as an example, a mechanism for determining a priority port for an inspection item with a short measurement time has been described, but this embodiment is not limited to this example, and it...

Abstract

In blood clotting tests, a reagent is mixed with a sample and a blood clotting reaction is initiated. The time from initiation until the reaction is complete is not fixed. As a result, during analysis, whether or not the blood clotting reaction is complete is judged at fixed intervals based on the measured amount of scattered light. Therefore, if the blood clotting reaction reaches completion morequickly than the predicted measurement time due to reagent or sample conditions, in some cases time is wasted and analysis cannot be conducted efficiently. Provided is an automatic analysis device and method that takes this problem into consideration. When information about a plurality of samples is entered into an operating unit, the device compares the predicted reaction time length of each requested analysis item for the plurality of samples, determines an analysis sequence to carry out the analysis for each analysis item in order from the longest predicted reaction time length, and carries out the analysis on the basis of the determined analysis sequence.

Description

technical field [0001] The present invention relates to a technology related to an automatic analyzer that automatically analyzes components such as blood. Background technique [0002] As a device for analyzing target components contained in biological samples such as blood, the following automatic analyzers are widely used for measuring single or The amount of transmitted light and scattered light of multiple wavelengths. [0003] Here, with regard to the automatic analysis device, in the field of biochemical examination, hematological examination, etc., there are biochemical analysis devices for quantitative / qualitative analysis of target components in biological samples, devices for detecting the coagulation force of blood, which is a sample, and so on. Devices for blood coagulation analysis, etc. [0004] In the case of the inspection items related to the former biochemical analysis, since the reaction time is predetermined, the measurement schedule can be arranged ac...
