Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an analysis slide and an analysis device.

[Description of Prior Art] As a method for chemically analyzing a liquid sample such as a body fluid sample, an analysis method using a chemical analysis element is known. This analysis method uses a filter paper-type analytical element made of a layered porous material impregnated with a specific reagent, or a sheet made of a transparent support with a reagent layer containing a specific reagent, a porous development layer, etc. An analytical element such as a shaped or film-like (integrated) analytical element (multilayer analytical element) is attached to or housed in a plate-like mount (analytical slide frame). A liquid sample to be detected is spotted or attached, and this is inked to generate a detectable reaction such as a color reaction involving the substance to be detected (analyte) in the sample. By measuring the progress or outcome of a reaction,
This consists of obtaining information such as whether or not an analyte is contained in the liquid sample or its content.

Various means can be used to detect changes caused by the reaction between the liquid sample and the reagent of the analytical element.
Generally, means for optically detecting the level of coloration appearing in a functional layer such as a reagent layer of an analytical element or the rate of coloration reaction is used.

Methods using optical detection means generally include the step of projecting light in a specific wavelength range on the analytical element according to the coloration that appears on the analytical element, and measuring the intensity of the reflected or transmitted light. However, light in this specific wavelength range is usually prepared by a combination of a light source and an optical filter. Therefore, a liquid sample analysis method that combines an analysis slide and an optical detection means as described in Section 2 is generally carried out using an analysis device equipped with a light source and an optical filter. However, an analyzer is not limited to just one type of analysis item, and usually many analysis items are set, so the operation of preparing light in the appropriate wavelength range for each analysis item is likely to be complicated, and errors may occur. etc. are also likely to occur.

[Object of the Invention] The present invention provides an analytical device that uses optical measuring means, which can simplify operation and prevent the occurrence of erroneous operations, and which is suitable for use in combination with the analytical device. The purpose is to provide analysis slides. A further object of the present invention is to provide an analysis method that uses the above-mentioned analysis slide and analysis device to simplify operations and prevent the occurrence of erroneous operations.

On the surface of the slide frame 23 of the analysis slide 21, there is a display means 24 detectable by magnetic means, for example, as shown in the figure. , - one or more magnetic tracks are provided. This magnetic information display means records various information regarding the analysis slide to which it is attached, and this analysis slide display means includes at least an optical filter necessary for optical measurement of the analysis slide. Information indicating directly or indirectly the type of information is recorded. Of course, this information may be recorded in the form of information regarding the type of analysis slide, analysis conditions for analysis item 1, and the like.

In addition, the display means to which analysis slides are attached,
For example, any other information such as the sensitivity of the analysis slide, the measurable range (measurement range), and the type of calibration curve may be recorded.

Since means for attaching magnetic information display means made of magnetic material to the surface of various molded products are already known, a detailed description thereof will be omitted. Note that the magnetic information display means of the analysis slide of the present invention may be provided with an unrecorded portion for writing (recording and accumulating) new information as desired.

A display means (internal record display means) attached to the analysis slide of the present invention that can be detected by magnetic means is provided on at least one side of the slide frame. The surface to which the magnetic recording and display means is attached may be the same as or opposite to the surface on which the sample is deposited on the analysis slide, depending on the analysis system used. Alternatively, a plurality of display means may be provided on one or both surfaces, or may be provided in combination with other known information recording and display means. The magnetic recording display means may be attached not to the slide frame of the analysis slide but to the surface of the analysis element housed therein, or to both.

The magnetic recording display means attached to the analysis slide of the present invention is preferably in the form of one or more lines, but may be any display means such as letters, dots, figures, bar codes, etc. , there is no particular limitation as long as it can be detected by magnetic means.

FIG. 3 is a schematic diagram showing a typical embodiment of the analyzer of the present invention.

The analyzer shown in FIG. 3 includes a measurement site 32 that defines a position for receiving and measuring an analysis slide 31, and a measurement area 32 for measuring a color reaction, etc. in an analysis element housed in an analysis slide placed at the measurement site 32. a light source 33 that projects light, a plurality of optical filters 34 (in FIG. 3, a plurality of optical filters are arranged near the periphery of one disk),

The above-mentioned analyzer has a display means (see Figure 2) that can be detected by magnetic means attached to the analysis slide 311.
For example, a magnetic reading head 36 is placed on a portion of said display means of a loaded analysis slide, and said head 36 is provided with a magnetic reading head 36 for processing the read information. An information processing mechanism 37 is attached.

The information I detected by the information processing mechanism 37 is then sent to the optical filter selection mechanism 35, where an optical filter corresponding to the analysis slide is selected based on the information via a driving means 38 such as a motor. 4) is selected from the plurality of optical letters 34, and the light source 3
It is placed in the optical path from 3. In addition, some kind of display means is attached to each optical filter, and by reading the information displayed by this display means, it is possible to check whether an appropriate optical filter has been selected. A mechanism may also be provided to allow for this.

Next, the state such as coloration appearing on the analysis element in the analysis slide 31 is projected onto the opening of the analysis slide 31 using light having a specific wavelength range that has passed through a filter from the light source 33, and the reflected light is received. Reflection photometry is performed by a photometry mechanism 39 including a mechanism.

In addition, in the above explanation of the analyzer, an example was shown in which the information recorded on the magnetic recording/display means of the analysis slide is read after the slide is placed in the same position as the spectroscopic measurement position, but the actual operation is different. In this case, it is desirable to read the magnetic records of the analysis slides well before the spectroscopic measurement process.Therefore, the operation of reading the above information should preferably be carried out after the analysis slides have been introduced into the analysis system. It is desirable to implement this at an early stage, and it is desirable to provide the reading mechanism at a separate location.

It should be noted that by adding a mechanism for displaying the information recorded on the display means of one analysis slide to the analysis apparatus of the present invention, it is also possible to visually check and confirm the necessary information. By providing such a display mechanism, in carrying out an analysis method using the analysis device of the present invention, first, information regarding the analysis slide recorded and stored in the magnetic information recording means of the analysis slide is read;
After displaying this on a display mechanism to visually confirm the information regarding the analysis slide, the method can be implemented such as performing the next steps such as optical measurements.
