2. Description of the Related Art In recent years, the content of a specific chemical component contained in the sample solution or its activity value, or the content of a formed component is quantitatively analyzed simply by spotting and supplying small drops of the sample solution. A dry-type integrated multi-layer analysis film (also referred to as a multi-layer analysis element or a multi-layer analysis element) that can be used has been developed and put into practical use. In addition, a filter paper type test piece and an improved single-layer or multi-layer test piece have been proposed, and some of them have been put into practical use.

In order to quantitatively analyze chemical components in a sample solution using such a dry analysis film, a sample solution having a development layer in the dry analysis film is used as a development layer.
For those that do not have a spreading layer, after direct spotting on the reagent layer,
This is kept at a constant temperature (incubation) in an incubator (incubator) for a predetermined time to cause a color reaction (a dye formation reaction or a color change reaction of an indicator dye), and then a predetermined biochemical substance in the sample solution and a dry analysis film are included. The chemical analysis slide is irradiated with irradiation light for measurement containing a wavelength preselected according to the combination with the reagent to measure its optical density, and from this optical density, the optical density previously determined and the predetermined biochemistry are determined. The calibration curve showing the correspondence with the substance concentration of the substance is used to determine the substance concentration (content) or activity value of the predetermined biochemical substance in this sample solution.

By the way, the above-mentioned monolithic multi-layer type dry analysis film has a structure in which at least one reagent layer containing a reagent is provided on a support made of an organic polymer, and more preferably, a developing layer is provided above the reagent layer. And is formed on a dry analysis film piece having a predetermined shape such as a square or a rectangle. For automatic operation, the dry analysis film piece is put into practical use as a chemical analysis slide held by an organic polymer mount. In addition, the inventors of the present invention have proposed a technique for directly loading a dry analysis film piece having no mount into a box of a cartridge, storing the cartridge in a film supply device of a biochemical analysis device, and sequentially taking out the measurement. is suggesting.

In supplying the dry analysis film, a large number of dry analysis films can be accommodated in a cartridge in order to load the film supply device and to automate the transport mechanism. US Pat. No. 5,043,143 It is disclosed in the specification, etc., and is sequentially taken out from this cartridge to perform spotting of the sample solution, conveyance, constant temperature maintenance by an incubator, and measurement.

[0006]

However, when a large number of dry analysis films are stacked in a storage container and the dry analysis films having the same shape are accurately overlapped, the dry analysis films are in a close contact state. Therefore, there is a problem that it is difficult to reliably take out the sheets one by one.

Specifically, the dry analysis film is taken out from the storage container by pushing out the plate-shaped slide member to send the dry analysis film located at the end from the side opening of the outlet, or It is conceivable that the dry analysis film at the take-out port is adsorbed and held by the adsorption pad inserted from the opening at the end of the storage container, and is moved laterally to be taken out, or is pulled and pulled out in the axial direction from the end.

However, in any case, in the case where the dry analysis film has a small thickness, in order to take out one by one, the slide member is used,
A slide member thinner than the thickness of the dry analysis film must be used, and the side opening must be set to be larger than the thickness of one sheet and smaller than the thickness of two sheets. The requirement for the size of the side opening is the same for the side opening by the suction pad, and those settings must be changed depending on the thickness of the dry analysis film to be stored.

Therefore, it is necessary to form a storage container corresponding to the thickness of the dry analysis film, which complicates the production and the storage of the adapted dry analysis film. Also,
In addition, it is difficult to separate the dry analysis films that are in close contact with each other by a simple mechanism or method.

The present invention has been made in view of the above circumstances, and a storage container for storing a dry analysis film so that the dry analysis films can be easily and reliably taken out one by one, a storage method for the storage container, and It is an object of the present invention to provide a method for taking out from this storage container.

[0011]

In order to achieve the above object, a container for a dry analytical film according to the present invention is provided for taking out the dry analytical film at one end of a side wall of a box for accommodating a plurality of laminated dry analytical films. In the storage container having a take-out port, the box body has a second dry-analyzing film adjacent to the first dry-analyzing film closest to the take-out port, and the second dry-analyzing film is placed at about 45 ° to about 90 ° to each other. Laminated in a state that they are offset from each other in a direction intersecting at an angle of the range, and similarly for the third and subsequent dry analysis films, the adjacent dry analysis films are also sequentially arranged at an angle of about 45 ° to about 90 °. They can be stacked and stored in a state where they are offset from each other in a direction intersecting with each other, and one of the outlets is provided at one end of each of two different side wall surfaces of the box body, and openings of the two outlets are provided. Width and height are substantially equal The direction in which the dry analytical film is taken out is a direction in which the dry analytical films cross each other at an angle in the range of about 45 ° to about 90 °.

[0012] Preferably, in the storage container, at least one regulating member for holding the laminated state of the dry analysis film is disposed inside the box body. As for the number of the regulating members to be installed, they can be held by providing them in at least one place according to the laminated state of the dry analysis film, but if the regulating members are arranged at the four corners, more reliable holding can be performed.

Further, when the dry analysis films of the dry analysis films which are stacked and stored in the storage container in a shifted state are arranged such that two adjacent dry analysis films intersect each other at an angle of 90 °, the dry analysis film of the storage container is formed. An outlet for taking out the analysis film is provided at one end of each of the two adjacent side wall surfaces of the box body, and the directions for taking out the dry analysis film at the two outlets intersect each other at an angle of 90 °. It is preferable to configure it in the direction to do.

As described above, the first dry analysis film closest to the outlet is crossed with the second dry analysis film adjacent to each other at an angle in the range of about 45 ° to about 90 °. When stacking in a state where they are staggered with respect to each other, the center positions of adjacent dry analysis films, that is, the center positions where the sample solution is spotted in the biochemical analysis device, are made to coincide with each other, and in this state, about 45 ° It is a particularly preferred embodiment that the rotation is offset by an angle in the range of about 90 °.

On the other hand, the method for storing the dry analytical film according to the present invention is as follows, in which the dry analytical film is placed in the container for the dry analytical film, which is the closest to the outlet.
Adjacent second dry analysis films are stacked in a state of being offset from each other at an angle in the range of about 45 ° to about 90 °, and the third and subsequent dry analysis films are also sequentially processed in the same manner. It is characterized in that adjacent dry analysis films are stored in such a manner that they are stacked in a mutually shifted state in a direction intersecting with each other at an angle of about 45 ° to 90 °.

Further, according to the method of taking out the dry analysis film of the present invention, one dry analysis film is stored in the storage container for the dry analysis film in which two adjacent dry analysis films are stacked in a mutually shifted state and stored. The first dry analysis film of the second dry analysis film adjacent to the first dry analysis film when the first dry analysis film closest to the outlet is taken out. It is characterized in that the first dry analysis film is taken out with a part of the region protruding from the edge of the film being pressed.

In the above-mentioned taking-out method, one of the protruding regions of the dry analytical film, which is the second closest to the take-out port in the receiving container, is provided by a holding lever arranged so as to be movable back and forth in the vicinity of the taking-out port of the receiving container. It is preferable to hold down the part.

[0018]

In the storage container of the present invention as described above, the dry analytical films stacked and stored in the storage container are positioned such that they are adjacent to each other at an angle in the range of about 45 ° to about 90 °. By shifting and storing, it is possible to easily separate the first dry analysis film that is closest to the outlet and the second dry analysis film that is adjacent to it by using the shifted position. The dry analysis film can be reliably taken out one by one, and for example, the allowable range of the size of the side opening of the take-out port can be expanded to facilitate the manufacture of the storage container and the dry analysis. The storage container having the same size can be used even if the thickness of the film changes, which increases versatility.

Further, as the dry analysis film, rectangular ones are alternately stacked in a direction orthogonal to each other and accommodated so that the dry analysis film can be displaced from the adjacent dry analysis film, and the length of the short piece at the outlet can be reduced. It is possible to surely take out the dry analytical films one by one by providing openings of a corresponding width at two orthogonal positions and taking out the dry analytical films alternately in the longitudinal direction. When the dry analysis film has a square shape, it can be stored by shifting its position by rotating it at a predetermined angle (for example, 45 degrees) and stacking.

Further, by providing a regulation member for holding the laminated state of the dry analytical film in the box body of the storage container, the position of the dried analytical film laminated and stored in a mutually shifted state can be surely held. Is.

Further, according to the above-mentioned taking-out method of the present invention, when taking out the first dry analytical film closest to the take-out port, the first dry analytical film of the second dry analytical film is taken out. By taking out the first dry analysis film in a state where a part of the region protruding from the edge is pressed, only one dry analysis film can be reliably taken out. By pressing the dry analysis film with a pressing lever that moves back and forth, the dry analysis film to be taken out can be easily separated from the next dry analysis film and only one can be taken out surely.

Bottom opening through which the suction pad 21 on the bottom passes
The width of 18 is formed narrower than the width of the side openings 17a, 17b. The suction pad 21 is moved up with its axis aligned with the center of the storage container 10 and inserted into the central bent portion of the bottom opening 18 to adsorb and hold the central portion of the lowermost dry analysis film 1 and its longitudinal direction. The dry analysis film 1 is taken out by sliding to. At that time, both ends of the second dry analysis film 1 are engaged with both ends of the side opening 17a or 17b in the sliding direction (see FIG. 4).
It is immovable in this sliding direction, and only the first sheet is reliably taken out from the side opening 17a or 17b.

Similarly, after the central portion of the dry analytical film 1 is adsorbed, the dry analytical film 1 is taken out in a direction orthogonal to the previous one, that is, in the longitudinal direction of the dry analytical film 1.

The above-mentioned dry analysis film 1 is provided by coating or adhering a reagent layer on a light-transmissive support made of a plastic sheet such as an organic polymer sheet such as polyethylene terephthalate (PET) or polystyrene, and is developed thereon. A film piece (chip) in which layers are laminated by a laminating method or the like, and does not have a mount corresponding to a mount in a conventional chemical analysis slide.

The above-mentioned reagent layer contains a hydrophilic polymer binder such as gelatin or a porous layer containing a detection reagent which selectively reacts with the analyte and a reagent (chemical analysis reagent or immunoassay reagent) necessary for color development reaction. It is composed of at least one layer. Further, the spreading layer is made of a material resistant to abrasion with the outside, for example, a woven fabric or a knitted fabric made of synthetic fibers such as polyester, a woven fabric made of a blend of natural fibers and synthetic fibers, a knitted fabric, a non-woven fabric, or paper. It functions as a protective layer and spreads so that the sample liquid spotted on the spreading layer can be uniformly supplied onto the reagent layer.

The analysis film 1 may be retracted so as to be released. The present example is also applicable to the case where the dry analysis film 1 is taken out from above the storage container 30.

According to the film take-out method using the presser levers 31 and 32 of this example, except for the dry analysis film 1 held on the suction pad 21, the take-out levers 31 and 32 restrict the take-out, and only the first film is taken out. The dry analysis film 1 can be reliably separated and taken out.

Next, FIG. 9 shows a square dry analysis film 2
An example is shown in which is stored in a storage container 40. The square dry analysis films 2 are stored in the storage container 40 in a state where they are alternately rotated by 45 degrees and displaced from each other.

The storage container 40 is provided with a groove-shaped regulating member (not shown) for holding the displaced position of the dry analysis film 2. In addition, the outlet formed in the lower portion is a side opening portion 42 in which a sideways opening and a diagonally extending opening are continuously formed on the side surface, and a suction pad on the bottom.
A fan-shaped bottom opening 43 for moving 21 is formed.

According to this example, even the square dry analysis film 2 is stored at a different position, so that the second dry analysis film 2 can be taken out depending on the difference in the taking-out direction. The movement of the dry analysis film 2 is prevented, and only the first dry analysis film 2 can be reliably taken out.

FIG. 10 is a bottom view showing a method of taking out the film by setting the holding levers 47 and 48 on the square dry analysis film 2. As in FIG. 9, the square dry analytical films 2 are alternately stacked at 45 degrees in the storage container 50 and stacked, and the stacked dry analytical films 2 are placed at the bottom of the box 51. An outlet 52 having a bottom opening 52a that can be inserted into is formed.

The presser levers 47, 48 are provided with a first set of presser levers 47 arranged on both sides in the lateral direction and a second set of presser levers 48 arranged in four oblique directions. .

Then, as in the case of FIG. 7, when the storage container 50 is loaded into the analyzer and the outlet 52 is opened, the first dry analysis film 2 is shown in FIG. The suction pad 21 is engaged and held by the first set of the presser lever 47.
When the first set of the presser levers 47 is released and then taken out, the second dry analysis film 2 is lowered and retained by the second set of presser levers 48, and the first set of dry analysis films 2 is held. Only 2 can be taken out surely and without any resistance.

In the example of FIG. 10, the dry analysis film 2 is used.
Not only the case of taking out downward, but also the case of taking out upward may be configured similarly.

Next, in the example shown in FIG. 11, the first dry analysis film 1 and the second dry analysis film 2 are separated when the rectangular dry analysis film 1 is taken out from the upper part of the storage container 60. It shows the method of taking out the film of
Pressing members 65 and 66 that operate integrally with the suction pad 21 or in synchronization with the movement thereof are provided.

In the illustrated case, rectangular dry analysis films 1 are alternately stacked at 90 degrees and stacked in a storage container 60, and an opening 61 for taking out is provided on the upper surface of the storage container 60.
An example is shown in which an outlet 61 having a is provided and the dry analysis film 1 is sequentially taken out from above. The pressing members 65, 66 are formed by springs, extend below the tip of the arm 64 fixed to the shaft of the suction pad 21, and have their lower ends abuttable on both ends of the dry analysis film 1. .

When the suction pad 21 descends, before the suction pad 21 sucks the first dry analysis film 1, the lower end portions of the holding members 65 and 66 respectively dry the first and second dry analysis films. It contacts the upper surfaces of both ends of the film 1 and presses it. When the first dry analysis film 1 is adsorbed and the adsorption pad 21 is moved upward, the first dry analysis film 1 is attached to the adsorption pad 21. Although it is held and rises as it is, the second dry analysis film 1 is urged downward by the pressing member 66 and separated from the first dry analysis film 1, and only the first dry analysis film 1 is separated. Is surely taken out.

As the pressing members 65 and 66, in addition to the spring, the suction pad 21 such as a weight is raised to lift the second dry analysis film 1 even when the first dry analysis film 1 is lifted. An urging mechanism having a structure that has an expanding and contracting action such as urging can be appropriately adopted.

Further, the dry analysis film 1 in the storage container 60
May be pushed up sequentially by a plunger member or the like, or the take-out position may be lowered sequentially without having a pushing up mechanism.

[0056]

According to the present invention, the dry analysis film is stored in the storage container while sequentially shifting the position of the dry analysis film from the adjacent dry analysis film, or the dry analysis film of the second dry type is stored by shifting this position. Hold the part of the analysis film that is protruding from the adjacent dry analysis film 1
Since the first dry analysis film is taken out, only the first dry analysis film can be reliably separated and taken out, and a mistake in taking out can be eliminated and reliability can be improved. Further, even if the thickness of the dry analysis film is changed, the influence on the taking-out is small, the taking-out can be performed surely, and the good analysis operation can be obtained without any trouble in the processing in the next step. .
