Description

  The present invention relates to an improvement of a disposable test plate used in an automatic analyzer. The present invention also relates to a test plate assembly in which a plurality of the test plates are stacked.

2. Description of the Related Art Conventionally, in hospitals and the like, various components contained in urine are analyzed, and urine is collected from the patient and analyzed in order to determine the health condition of the patient from the analysis result.
This applicant has invented an automatic urine dispensing device that can fully automatically dispense urine from a Harun cup to a test tube and apply a patient identification label to each test tube, and has already filed a patent application. (Patent Document 1).
However, since urine tests are frequently performed, the consumption of test tubes and labels is considerably increased. For this reason, it is desirable to reduce the consumption of test tubes and labels. However, when all analyzes are performed with a dedicated analyzer as in the prior art, the consumption of test tubes and labels cannot be reduced.
The applicant pays attention to the above-mentioned problems, and can perform qualitative analysis without dispensing urine into the test tube. At the same time, the applicant can transfer from the Harun Cup to the test tube for quantitative analysis or sedimentation analysis, if necessary. Proposed a qualitative analysis device equipped with an automatic dispensing mechanism that can dispense urine and automatically attach a patient identification label to a test tube (Patent Document 2).
In the qualitative analysis apparatus according to Patent Document 2, a plurality of test papers each provided with a plurality of reagent pads are stored on an elongated support, and the stored test papers are taken out one by one and sequentially placed at a spotting position and a measurement position. Configured to send.
However, in order to sequentially take out and send independent test papers one by one in this way, a complicated transfer structure is required, and in the case of individual test papers one by one, since the test paper is small, There is a problem that the test paper may drop or shift, and the test paper is often wasted.
In order to solve the above-mentioned problems, the applicant forms a plurality of test sections for one specimen having a plurality of reagent sections in a radial manner on a disposable disc main body at intervals. A test plate was invented and a patent application was filed (Patent Document 3).
FIG. 8 is a schematic top view of the test plate previously proposed by the applicant, and FIG. 9 is a cross-sectional view taken along line XX in FIG.
This test plate E has a disk-shaped disc body E2 in which an outer peripheral wall E1 extending downward is formed around the test plate E. A flange E3 extending radially outward is formed at the lower end of the outer peripheral wall E1.
On the upper surface of the disk main body E2, a plurality of inspection portions E4 made of elongated concave portions extending in the radial direction are formed at intervals, and a test paper E5 is accommodated in each inspection portion E4.
And, on the upper part of the outer peripheral wall E1 of the test plate, there are six locking portions E6 projecting radially outward at intervals of 60 degrees, and when the test plates E are stacked, the flange of the upper test plate The bottom surface of E3 is locked to the locking portion E6 of the lower test plate so that the upper and lower test plates E are stacked without being fitted to each other.

JP-A-10-142235 JP 2006-275697 A Japanese Patent Application 2011-29846

According to the test plate E described above, a plurality of test plates E can be stacked and stored without being fitted to each other by the locking portion E6 provided on the outer peripheral wall E1.
However, as shown in FIG. 8, the above-described conventional test plate E has a problem that the releasability is poor at the time of molding because the engaging portion E6 is provided on the upper portion of the outer peripheral wall E1.
The inventors have found that the locking portion E6 is formed in the shape of a groove extending in the height direction of the outer peripheral wall E1 in order to solve the problem of releasability. Problems arise.
Here, in order to clarify the problem, the usage state of the test plate will be described.
The test plate configured as described above is usually sold and transported in a packaged state of an assembly in which a plurality of test plates are stacked. And it is stored in the state of the stacked assembly also in the hospital or laboratory, and is set in the analyzer or the like with the stacked assembly in use. Thus, the test plates are in a stacked state until they are actually used in the analyzer. For this reason, for example, a load may be placed on the test plate assembly during transfer or storage before being set in the analyzer, and a force may be applied to the test plate assembly from above and below.
On the other hand, when the engaging portions formed in the groove shape extending in the height direction of the outer peripheral wall as described above are formed at equal intervals on the outer peripheral wall as in the previously proposed test plate, the upper and lower test plates In some cases, the positions of the locking portions may be all matched.
When a force is applied to the test plate assembly from above and below in a state where all the positions of the locking portions are matched, the locking portion of the upper test plate becomes the locking portion of the lower test plate. The problem arises that the upper and lower test plates fit into each other completely.
The present invention solves the above-mentioned conventional problems and can reduce the possibility that the upper and lower test plates are completely fitted to each other even when force is applied from the vertical direction in a state where a plurality of sheets are stacked. An object of the present invention is to provide a plate assembly, and to provide a test plate assembly in which the upper and lower test plates do not completely fit each other even when a force is applied from above and below.

In order to achieve the above-described object, the disposable test plate according to the present invention includes a plurality of test sections for a single sample having a plurality of reagent sections spaced apart from each other on a disposable disc body. A disposable test plate used in an analyzer for spotting a specimen on a test reagent part and optically measuring the color reaction of the test reagent part, wherein the disc body is disposed downward on the outer periphery thereof. The outer peripheral wall has a flange extending outwardly at the lower end of the outer peripheral wall, and the outer peripheral wall has a convex or concave shape extending from the upper end to the lower end of the outer peripheral wall along the height direction of the outer peripheral wall. The engaging portions are arranged at irregular intervals in a plurality of circumferential directions.
In addition, the disposable test plate assembly according to the present invention includes a first test plate in which convex or concave engaging portions are provided on the outer peripheral wall at irregular intervals in a plurality of circumferential directions, and a convex or concave shape on the outer peripheral wall. The locking portion is formed by alternately stacking second test plates that are provided at irregular intervals in a plurality of circumferential directions at intervals different from those of the first test plate.

The disposable test plate according to the present invention comprises a plurality of test parts for one specimen provided with a plurality of reagent parts spaced apart from each other on a disposable disk body, and the specimens are provided in the test reagent parts. A disposable test plate used in an analyzer that optically measures the color reaction of a test reagent part, wherein the disc body has an outer peripheral wall extending downward on the outer periphery thereof, and the outer periphery A flange extending outwardly at the lower end of the wall, and a plurality of convex or concave engaging portions extending from the upper end to the lower end of the outer peripheral wall along the height direction of the outer peripheral wall are arranged at an inappropriate interval on the outer peripheral wall. Therefore, the releasability at the time of molding is good, and the possibility that all the latching parts of the upper and lower test plates match when stacking multiple sheets is extremely low. Plates can fit completely together There is an effect that it is possible to be significantly reduced.
In addition, the disposable test plate assembly according to the present invention includes a first test plate in which a plurality of convex or concave engaging portions are provided on the outer peripheral wall at irregular intervals, and a convex or concave engaging portion on the outer peripheral wall. However, since the second test plate provided at a plurality of unfair intervals is alternately stacked at a different interval from the first test plate, all of the locking portions of the upper and lower test plates are stacked when a plurality of the test plates are stacked. The possibility of matching is completely eliminated, and the upper and lower test plates do not completely fit each other even if a force is applied to the assembly from above and below during transport or storage.
If the analyzer is refilled with test plates, the new assembly will be placed on the rest of the previous assembly, in which case the test plate at the top of the previous assembly will be The test plate at the bottom of the assembly to be replenished may also be the first test plate. However, even in such a case, since the locking portions of the first test plate and the second test plate are provided at inappropriate intervals, all the locking portions of the upper and lower test plates are matched. The possibility is very low and the possibility that the upper and lower test plates fit completely together is very low.

  Hereinafter, an embodiment of a disposable test plate according to the present invention will be described with reference to one embodiment shown in the accompanying drawings.

  1 is a top view of an embodiment of a test plate, FIG. 2 (a) is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 2 (b) is a cross-sectional view taken along the line BB in FIG. 3A is a sectional view taken along the line CC in FIG. 1, FIG. 3B is an end view taken along the line DD in FIG. 1, and FIG. 3C is a sectional view taken along the line EE in FIG. Yes.

As shown in these drawings, the test plate A has a disk-shaped disc main body A2 in which an outer peripheral wall A1 extending downward is formed around the test plate A. A flange A3 extending radially outward is formed at the lower end of the outer peripheral wall A1.
At the center of the test plate A, there is formed a locking portion A4 that is locked to a turntable (not shown) of the automatic analyzer, and a donut-shaped groove A5 is formed so as to surround the locking portion A4. A donut-shaped protrusion A6 is formed around the donut-shaped groove A5. Although not shown, the turntable is equipped with a single test plate A and transports the test plate A from the storage position to the spotting and analysis positions, or the test plate is placed at the spotting and analysis positions. It is configured to rotate.

On the upper surface of the disk main body A2 of the test plate A, a plurality of inspection portions A9 made of elongated concave portions extending in the radial direction are formed at intervals from each other (22 in this embodiment). A plurality of protrusions A10 are formed on the side walls of the recesses forming the inspection portions A9 so as to accommodate and hold the test paper inside.
Each test section A9 is provided with a test paper A12 having a plurality of test reagent sections A11 carrying a reagent that reacts with the substance to be detected in the sample and develops a color on the strip, and each test section A1. Functions as an inspection unit for one specimen. Although the test paper A12 is omitted in FIG. 3, basically, the test paper A12 is attached to all the inspection sections A9.
Further, a label A13 on which an individual identifier converted into an electronic code is printed in the form of a barcode or the like is attached to the disk main body A2 of the test plate A. Further, a color sample serving as an internal standard for optical measurement can be printed on the label A13. In the individual identifier, in addition to the identification information that can identify the individual disposable test plate A, in the case where a color sample is printed, color information relating to the color sample (color sample serving as an internal standard for optical measurement). Can be included. Specifically, the color information of the color sample may be, for example, an RGB value and a light / dark value.
In this embodiment, the label A13 on which the individual identifier and the color sample are printed is affixed to the disc main body A2. However, the individual identifier and the color sample may be directly printed on the disc main body A2, or the individual identifier. May be configured with a tag or the like.

The test plate A has a locking portion between its central portion and its outer peripheral portion.
On the side wall of the doughnut-shaped groove A5 provided in the central portion of the test plate A, inner locking portions A7 projecting radially inward are formed at four positions at an unjustified interval (see FIGS. 1 and 2). ). As shown in FIG. 2, these inner locking portions A7 are formed so as to extend substantially vertically along the height direction of the side wall from the middle position in the height direction of the side wall of the groove A5 to the lower end.
Further, on the outer peripheral wall A1 of the test plate A, groove-shaped outer locking portions A8 that are recessed inward in the radial direction are formed at twelve locations at an inappropriate interval. These outer locking portions A8 are formed so as to extend from the upper end to the lower end of the outer peripheral wall A1 along the height direction of the outer peripheral wall A1 (see FIGS. 1 and 3). In these outer locking portions A8, the intervals between the adjacent outer locking portions A8 are unequal as described above. Specifically, for example, in the illustrated embodiment,
The interval between the locking portion A8-1 and the locking portion A8-2 is 27 °,
The interval between the locking portion A8-2 and the locking portion A8-3 is 30 °,
The interval between the locking portion A8-3 and the locking portion A8-4 is 23 °,
The interval between the locking portion A8-4 and the locking portion A8-5 is 26 °,
The interval between the locking portion A8-5 and the locking portion A8-6 is 30 °,
The interval between the locking part A8-6 and the locking part A8-7 is 29 °,
The interval between the locking portion A8-7 and the locking portion A8-8 is 35 °,
The interval between the locking portion A8-8 and the locking portion A8-9 is 25 °,
The interval between the locking portion A8-9 and the locking portion A8-10 is 21 °,
The interval between the locking portion A8-10 and the locking portion A8-11 is 34 °,
The interval between the locking portion A8-11 and the locking portion A8-12 is 28 °.
As described above, by providing the locking portions A7 and A8, when the test plate A is stacked, the bottom surface of the groove A5 of the upper test plate A is placed on the inner locking portion A7 of the lower test plate A. The outer locking portion A8 of the upper test plate A rests on the disc body A2 of the lower test plate A, and the upper and lower test plates A do not fit completely (see FIG. 4).
Further, since the locking portions A7 and A8 are provided at unequal intervals, the position of the locking portion A8 of the upper test plate A and the locking portion of the lower test plate A when the test plate A is stacked. The possibility that all the positions of A8 match will be very low, so even if a force is applied from above or below to a test plate assembly in which a plurality of test plates are stacked, the upper and lower test plates fit each other. The possibility is very low.
Further, all the inner locking portions A7 are formed so as to extend substantially vertically along the height direction of the side wall from the intermediate position in the height direction of the side wall of the groove A5 to the lower end, and the outer locking portion A8 is formed on the outer peripheral wall A1. Since it is formed so as to extend from the upper end to the lower end along the height direction, the locking portion is not caught by the mold at the time of molding, so that the releasability becomes good and mass production becomes possible.
