Generally, a biochemical analysis using a reaction reagent is performed on a liquid sample such as blood or serum when it is necessary to know whether or not a specific component is contained in the liquid sample, or the content thereof. Among these methods for liquid samples, the dry method uses a chemical analysis slide, which is a biochemical analysis element (measuring element),
A liquid sample to be analyzed is dripped onto the slide, placed in a thermostatic chamber for reaction, and the liquid sample and reagent are allowed to react. This is a method of measuring and detecting (optical density change at a certain measurement wavelength) using an optical density meter or other means, and is very convenient in that it can actually treat a liquid sample as a solid. . However, conventional chemical analysis slides have a PIIJ shape that has an axis of symmetry (one-point frequent line) when viewed in the insertion direction.
(See Figure 14), there is a possibility of inserting the front and back sides backwards.
The dropping surface of the analysis slide was reversed, causing the drop to be applied to a surface that was not originally intended for dropping, and the photometric surface was reversed, resulting in photometric errors. FIG. 14 shows a schematic diagram of the insertion opening 4 and the analysis slide 1a, which is a biochemical analysis element stacked thereon, from the insertion direction, where 2 is the analysis film, 3 is the mount, and the direction perpendicular to the page is the insertion direction.

Embodiment 1 Next, the present invention will be described based on an embodiment shown in the accompanying drawings. 1 is an analytical element, 102 is a mount cover, 106
The dropping opening 3 for dropping a sample is a mount, and the reference numeral 2 is a chemical analysis film which is a biochemical analysis member. The chemical analysis film 2 is formed by forming a reagent layer 2b on the upper surface of a transparent support 2a and laminating a developing layer 2C on the upper surface of the reagent 12b, as shown in FIGS. 1^ and 1B. This spreading layer 2C is for spreading the liquid sample dropped onto it in the surface direction and causing it to react with the reagent layer 2b. The mount 3 is desirably made by plastic molding from the viewpoint of productivity, operability, cost, etc., and is provided with a constriction section 10 in its central region into which the chemical analysis film 2 can be loaded. This embossed portion 10 is formed by air pressure molding.
The result is the same whether the molding is performed by vacuum forming or press molding. Further, the mount 3 may be molded from a transparent plastic material or from an opaque plastic material. In the former case, since the chemical analysis film 2 loaded in the narrowing section 10 can be seen through from the bottom surface,
Although it is not necessary to provide a through hole for photometry on the bottom of the diaphragm 10, in the latter case, the diaphragm 10 is
A condition is that a through hole 11 for photometry is formed at the bottom of the photometer. The diameter of the through hole 11 is determined in relation to the irradiation area of the photometric light beam during photometry. The chemical analysis film 2 loaded in the constriction part 10 of the mount 3 is joined by appropriate means (for example, adhesion with an adhesive, welding with ultrasonic waves, etc.). Because of this shape, 1 is vertically asymmetrical. FIG. 2 is a front view showing the internal structure of the biochemical analyzer with a part of its outer frame broken away, FIG. 4 is a perspective view of the device, and FIG. 3 is a plan view of the device showing the inside. 20 is an insertion opening into which the slide 1 is inserted, and 21 is a first insertion opening inserted through the insertion opening.
The roller 23 that conveys the same slide 1 as shown in the figure to the conveyor belt 22 is an aperture provided in the conveyor belt 22 so that the measurement light can pass therethrough. 24 is a heat insulating plate (constant temperature plate) for keeping the temperature of the slide 1 constant. The slide)'1 inserted from the insertion port 20 is the roller group 2.
1, the sample 5 is sent to a conveyor belt 22 that performs intermittent movement, and then the sample 5 is dropped from the dripping part by the conveyor belt 22, and after being kept warm for a predetermined time by a heat insulating plate 24, it is transferred to a photometry section 25, where at least light is emitted. Means 26,
After the optical density is measured by a photometric means having a light receiving means 27, it is discharged from the discharge port 28. Measurement results based on optical density are printed out by a printer (not shown). In the above configuration, chemistry slide 1 is vertically asymmetrical (
(does not have a symmetrical plane extending left and right), and the insertion opening 2
0 is also configured vertically asymmetrically (it does not have a symmetry axis extending left and right), so even if you try to insert a chemical slide with the front and back reversed, it will appear as a broken line and cannot be inserted. Here, we have explained a case in which the element (chemical slide) that is transported to the photometric section during photometry as a biochemical analysis unit is vertically asymmetric. However, as described next, chemical slides are not vertically symmetrical like conventional Of course, the present invention also includes a configuration in which the cartridge is vertically asymmetrical when the cartridge is inserted into the insertion port 20. FIG. 5 is a schematic cross-sectional view taken along line XX in FIG. 6 showing the structure of this unit, and 30 is a cartridge having an inner upper part 30-1 made of a sponge or the like so as to be elastically pressed downward. , 1a is a vertically symmetrical analysis slide, and by a predetermined rotating roller of the roller group 21 that is urged upward, the analysis slide is slightly lifted upward against the force of the above-mentioned 30-1, and the cartridge 30, is sent to the other rollers of the roller group 21, and further sent to the conveyor belt 22. (See Figure 6). In this case, as can be seen from the figure, the insertion opening has an upside-down shape compared to that in FIG. 2. 50 is a locking member provided on the cartridge 30. Even with this configuration, the analytical element (slide) can be inserted with the predetermined front and back sides, and does not have the drawbacks of the conventional method. Furthermore, the first
As shown in Figures to Figure 4, in cases where the analysis unit (= analysis element) is directly inserted into the insertion port, the analysis unit (= analysis element) is
A square shape with multiple axes of symmetry in front, as shown in the figure, is preferable because it allows for many insertion directions depending on the number of axes of symmetry, and it can be inserted without making a mistake between the front and back sides as shown in Figure 7. However, if the slide has a code indicating the analysis item (see Japanese Patent Application No. 60-39875), the element surface should be made rectangular to limit the insertion direction, and the width of the insertion opening should be about the length of the short side. It is preferable to use it as an element for a device with Furthermore, if an analytical element 1b shaped like the analytical element 1b, which is asymmetrical both vertically and horizontally in the insertion direction, is used in an insertion opening which is asymmetrical horizontally and vertically as shown in FIG. It is preferable if the element has a code, such as. In addition, f! FIG. 8(A) shows the vertically asymmetrical insertion opening and the vertically asymmetrical slide 1b, and FIG. 8(B) shows a perspective view of the slide 1b. The above example shows an example in which the analysis unit is inserted horizontally, that is, perpendicular to the dripping direction, but next, the analysis unit, specifically,
An example of inserting the analytical element into the insertion section from above is shown in Figures 9-t.
This will be explained using diagrams j & 12. The main body insertion port 20-1 is sufficiently thick (the insertion port 20 has a shape as described later).
It is almost the same as Fig. 4. In this example, the push-in member 33
The slide IC inserted into the insertion slot 20 of is pushed into the closet 20-1 along the rail member 34 and has almost the same shape as the insertion slot 20 provided in the rail member.
It is configured such that it is sent to the transport belt 22 and from there onto the transport belt 22. (See the dashed line in Figure 9) Here,
The insertion port 20 is trapezoidal with no axis of symmetry, and the slide IC is also trapezoidal with no axis of symmetry, so the insertion method is -
If the cord is inserted as shown in FIG. 11 without being inserted upside down, the cord will face in a predetermined direction. In addition, FIG. 9 is a schematic side view (partial cross section) of the main part of this example, FIG. 10 is a schematic plan view of the main part of this example, FIG. 11 is a schematic plan view of the element (slide), and FIG. 12 is a schematic plan view of the main part of this example. FIG. 3 is a perspective view of main parts. Next, the shape of the analysis element and the shape of the insertion port are listed in FIG. avbte indicates an analytical element, a is a perspective view, b is a plan view, C is a front (side) view, and d is the shape of the insertion port. The example shown in the figure is an example of an analytical element and insertion port that are vertically asymmetrical and horizontally symmetrical, the example marked ■ is an example of an analytical element and insertion port that are asymmetrical both vertically and horizontally, and the example marked ■ is an example that has an axis of symmetry in a plane. This is an example of an analytical element that does not have an axis of symmetry and an insertion port that does not have an axis of symmetry. still,
It goes without saying that the position indicated by K may not be a flat member as shown in the figure, but may be a protruding member as shown in FIG. 8(A) 41. The present invention is preferably used in the apparatus disclosed in Japanese Patent Application No. 60-39875, particularly as shown in FIG. 7 of the same apparatus. Furthermore, it goes without saying that a configuration in which a protrusion piece, for example, one protrusion piece is attached to the mount shown in FIG. 14 in order to make it asymmetrical, is also included in the analysis unit of the present invention. Effects of the Invention As described above, according to the present invention, it is possible to eliminate photometry errors and dripping errors caused by inserting the biochemical analysis unit upside down.
