Embodiment 1

[0032] A case will be described in which light receivers are placed at positions of 20° and 30° with respect to the light emitted from the light source as multiple light receiving angles for measuring scattered light, and whether the dynamic range or high sensitivity is given priority by the user is based on this Specify the reaction process data measured by the corresponding light receiving angle, and display the quantitative results.

[0033] Figure 5 It is a schematic diagram showing an example of the overall configuration of the automatic analyzer of the present invention. This automatic analyzer is equipped with a scattered light measurement circuit. The automatic analysis device is mainly composed of the following three disks: a sample disk 3, a reagent disk 6, and a storage box disk 9, a dispensing mechanism for moving samples and reagents between these disks, a control circuit 23 for controlling them, and a light-transmitting mechanism. The measurement circuit 24, t...

Embodiment 2

[0051] A case will be described in which light receivers are placed at positions of 20° and 30° relative to the light emitted from the light source as multiple light receiving angles for measuring scattered light, and the calculation is performed as a change in light quantity for a certain period of time based on reaction process data. When the result falls outside the measurement range specified by the lower threshold and upper threshold, the light receiving angle of the reaction process data used to calculate the quantitative value is automatically selected, and the dynamic range is expanded.

[0052] The basic conditions are the same as in Example 1, but the flow before displaying the user's setting screen before the measurement and the quantitative result after the measurement is different.

[0053] exist Figure 9 An example of the user setting screen before measurement in Example 2 is shown in . The user designates an inspection item name for a sample on a sample tray d...

Embodiment 3

[0059] A case will be described in which quantification is performed based on reaction process data at designated light receiving angles, and when these quantitative values ​​differ by a certain value or more, the results of the light receiving angle designated as priority display based on the quantitative values ​​are displayed.

[0060] The basic conditions are the same as in Example 2, but the flow before displaying the user's setting screen before the measurement and the quantitative result after the measurement is different.

[0061] exist Figure 12 An example of the user setting screen before measurement in Example 3 is shown in . It is basically the same as Embodiment 2, but a quantitative warning value for checking whether to display a warning can be set.

[0062] It is also possible to compare the respective quantitative values ​​calculated from the reaction process data of the light receiving angle specified on the setting screen, and display a warning when the dif...

Abstract

It is an object of the present invention to obtain desired quantitative results without changing the device structure and reagents for measurement with a wide dynamic range and high sensitivity. Therefore, in the present invention, an automatic analysis device is provided, which measures the time-series data of the amount of scattered light as the reaction process data, and quantifies the concentration of the substance to be measured according to the change in the amount of light, and has the ability to measure In the reaction process data, select the function for quantifying the reaction process data. By using this function, data can be selected from reaction process data measured with multiple light receivers at different angles according to the high sensitivity priority that prioritizes the concentration or sensitivity of the measurement object, or the dynamic range priority, and the quantitative results can be displayed.

Description

technical field [0001] The present invention relates to an analysis device for measuring the concentration of a measurement substance contained in a sample, for example, an automatic analysis device for quantifying the concentration of a measurement substance contained in blood or urine. Background technique [0002] The following automatic analyzers are widely used. Light from a light source is irradiated to a reaction solution mixed with a sample and a reagent, and the absorbance is calculated from the change in the amount of transmitted light at a specific wavelength, and the concentration of the measured substance is calculated according to the Beer-Lambert law. Quantitative (for example, Patent Document 1). In these devices, a plurality of cassettes holding a reaction solution are arranged on the circumference of a cassette disk that repeatedly rotates and stops, and the transmission light measuring unit arranged at a predetermined position is controlled by the transmit...
