Description

  The present invention relates to an analysis substrate and an analysis apparatus for performing analysis of a sample, particularly physical or chemical analysis.

  In recent years, for example, techniques for analyzing samples such as biological samples have been remarkably developed. For example, analyzers that analyze DNA, RNA, proteins, and the like have been developed one after another. Due to the development of analytical technology, there is a growing need for devices that perform assays (analyses) quickly, efficiently, accurately and at low cost.

  As one of such analyzers, by reading an assay element into a part of a compact disc (CD) or digital video disc (DVD), the software pre-recorded on the CD or DVD is read by a reader. An apparatus for controlling a process from before to after an assay using a protocol included in the software has been proposed.

  For example, Patent Document 1 discloses a disk called a biocompact disk as an example of an analysis instrument used in the analysis apparatus. A plan view of this biocompact disc is shown in FIG. As shown in FIG. 12, the biocompact disc 80 includes an assay sector 81 and a software sector 82 which are divided in the circumferential direction. The biocompact disc 80 has a diameter of 20 to 200 mm and a thickness of 0.5 to 3 mm. This biocompact disc 80 is loaded into a conventional CD-ROM or DVD reader and rotates. A central hole 83 is provided in the biocompact disc 80 for loading into such a reader. By controlling rotation with a reader, reagents and samples can be delivered to appropriate sites on the assay sector 81 for incubation, electrophoresis, isoelectric focusing, and the like. Protocols such as rotation speed and rotation timing control are recorded in the software sector 82 in advance.

As described above, there have been proposed devices and biocompact discs that can reduce costs and perform centrifugation by rotating by using a CD or DVD as described above. Therefore, it is possible to accurately perform digital analysis of a sample at a treatment base such as a hospital or at home.
Special Table 2000-515632 (announced on November 21, 2000) JP 2003-66003 A (published on March 5, 2003)

  However, the conventional biocompact disc 80 does not disclose a method for using or storing analytical data as a result of the assay. Therefore, for example, after analysis at a treatment base such as a hospital or at home, the analysis data is part of the medical record, for example, a patient who is an analysis subject (subject, measurement subject), or brought to another treatment base. Cannot be used for diagnosis or treatment.

  Here, in order to hold the analysis data, the read-only software sector 82 in the conventional biocompact disc is replaced with a recording medium in a CD-R or CD-RW to form an information sector which is a recordable area. A method is easily conceived.

  When a plurality of unrelated assays are performed using this recordable biocompact disc, the assay may be performed for each of the plurality of biocompact discs and the analysis result recorded. However, when there is some related information among a plurality of assays, for example, when a time-series sample assay is performed for a single patient, it is better to record progress information for each assay on each biocompact disc. As described above, there is no description about the recording of related information between a plurality of assays in the above conventional example.

  The present invention has been made in view of the above problems, and an object of the present invention is to realize an analysis board and an analysis apparatus that are convenient when performing a plurality of related analyses.

  In order to solve the above problems, an analysis substrate of the present invention includes an analysis area in which a sample can be analyzed and a recording area in which information can be recorded, and the recording area is performed in the analysis area. And a registration information recording area in which registration information, which is information relating to analysis of the sample, is recorded.

  According to said structure, registration information, for example, the sample used for analysis, analysis conditions, a date, etc. are recorded on a registration information recording area. Therefore, for example, when analyzing another sample of the same patient (for example, a sample of a medical condition), first, the registration information is read from the registration information recording area of the first analysis board that has been used for the analysis of the sample of the patient. Later, the analysis can be performed on the second analysis board, which is another new board, and the new registration information can be recorded on the second analysis board based on the registration information of the first analysis board. That is, registration information reflecting information on the analysis on the first analysis board can be recorded on the second analysis board, and related information can be taken over for each of a plurality of analyses. Thereby, the convenience in performing a plurality of related analyzes can be improved.

  When the analysis region includes a plurality of analysis units (analysis chips), the above-described plurality of analysis substrates may be replaced with a plurality of analysis units. That is, after reading the registration information for the first analysis unit from the registration information recording area, the analysis is performed by the second analysis unit in the same analysis board, and the new analysis is performed based on the registration information for the first analysis unit. Registration information (registration information about the second analysis unit) is recorded. Therefore, new registration information reflecting registration information related to the previous analysis can be recorded in the same analysis board, and related information can be taken over for each of a plurality of analyzes in the same board. Thereby, the convenience in performing a plurality of related analyzes can be improved.

  The analysis board may include a dividing unit for separating the analysis area and the recording area.

  According to this, after recording analysis data and registration information in the recording area, the recording area and the analysis area are divided, the recording area is used as analysis data afterwards, and the analysis area is stored to prevent secondary diseases and environmental pollution. It can be stored in a warehouse.

In the above analysis board, the analysis region may be configured to include identification information unique to each analysis board.

  According to this, after the analysis area and the recording area are divided, the analysis area and the recording area can be collated based on the identification information. If collation is possible, falsification of analysis data and creation of forged data in the recording area can be prevented.

  In the above analysis substrate, the recording area may include a data recording area in which analysis data, which is data indicating a result of analyzing a sample in the analysis area, is recorded.

  According to this, not only the registration information but also analysis data can be recorded in association with new analysis data together with the previous analysis data, and convenience is improved.

  The analysis substrate is formed in a disk shape, the analysis area is disposed at an outer position in the disk radial direction, and the recording area is disposed at an inner position in the disk radial direction with respect to the analysis area. The dividing part may be formed between the analysis area and the recording area.

  According to this, since the recording area in which the analysis data is recorded can be a small disc, it can be reproduced by the disc reproducing apparatus. In the analysis disk, the diameter of the small disk including the recording area separated from the dividing area may be set to the standard diameter of the optical disk. For example, the diameter of the entire analysis disc is 12 cm in accordance with the standard of a compact disc or a digital video disc, and the diameter of the small disc including the recording area after division by the division area is the same as the small diameter size (8 cm) of the standard. In this case, a small disk including the recording area can be reproduced by a commercially available CD-ROM device or the like, and convenience is further improved.

  The analysis apparatus of the present invention uses any of the above-described analysis substrates, and the registered information includes information used for control of analysis performed in the analysis region, and analyzes the sample in the analysis region. Analyzing means for performing recording, recording means for recording the registration information in the registration information recording area, reproduction means for reading the registration information, and controlling the analysis operation by the analysis means using the read registration information And a control means.

  According to this, registration information such as a sample used for analysis, analysis conditions, date and time is recorded in the registration information recording area by the recording means. Therefore, for example, when analyzing another sample of the same patient (for example, a sample of a medical condition), first, the registration information is reproduced from the registration information recording area of the first analysis board that has been used for analyzing the sample of the patient. After the reading, the analysis is performed on the second analysis board, which is another new board, according to the instruction of the control means, and the new registration information is recorded on the second analysis board based on the registration information of the first analysis board. be able to. That is, registration information reflecting information on the analysis on the first analysis board can be recorded on the second analysis board, and related information can be taken over for each of a plurality of analyses. Thereby, the convenience in performing a plurality of related analyzes can be improved. The same applies to the case where the analysis region includes a plurality of analysis units (analysis chips).

  In the analysis apparatus, the analysis region includes a plurality of independent analysis units capable of analyzing a sample, and the registration information includes information on whether each analysis unit is used or not. In addition, the control unit may be configured to control the analysis unit so that the analysis is performed in an unused analysis unit indicated by the registration information read by the reproduction unit.

  According to this, when a plurality of analysis units (analysis chips) are provided in one analysis substrate, it is possible to avoid a situation in which analysis is performed in an analysis unit that has already been used. That is, no analysis is performed by injecting a new reagent or sample by mistake into an analyzer that already contains a reagent or an old sample. Therefore, it is possible to reliably select an unused analysis unit and perform analysis.

  In the analysis apparatus, the registration information includes information indicating whether the analysis area is used or not, and the recording unit uses the registration information read by the reproduction unit to store the first analysis board. The configuration may be such that, when it is indicated that all of the analysis area has been used, the registration information is recorded on a second analysis board having an unused analysis area.

  According to this, when all of the analysis area is used on the first analysis board, the registration information can be transferred to the new board (second analysis board). Here, the fact that all analysis areas are used means that if there is only one analysis area (analysis unit) in the analysis area, that area has been used. If a plurality of areas (analyzers) that can be analyzed are provided in the area, it means that all of them are used. According to such a configuration, it is possible to continuously use the plurality of analysis boards while taking over the registration information between the plurality of analysis boards (the first analysis board and the second analysis board).

  The analysis substrate according to the present invention includes an analysis area in which a sample can be analyzed and a recording area in which information can be recorded, and the recording area is information relating to the analysis of the sample performed in the analysis area. A registration information recording area in which registration information is recorded is provided.

  The analysis apparatus of the present invention is an analysis apparatus using the above-described analysis substrate, wherein the registration information includes information used for controlling analysis performed in the analysis area. Analysis means for analyzing a sample, recording means for recording the registration information in the registration information recording area, reproduction means for reading the registration information, and using the read registration information in the analysis area Control means for controlling the analysis of the sample.

  According to said structure, registration information, for example, the sample used for analysis, analysis conditions, a date, etc. are recorded on a registration information recording area. Therefore, for example, when analyzing another sample of the same patient (for example, a sample of a medical condition), first, the registration information is read from the registration information recording area of the first analysis board that has been used for the analysis of the sample of the patient. Later, the analysis can be performed on the second analysis board, which is another new board, and the new registration information can be recorded on the second analysis board based on the registration information of the first analysis board. That is, registration information reflecting information on the analysis on the first analysis board can be recorded on the second analysis board, and related information can be taken over for each of a plurality of analyses. Thereby, the convenience in performing a plurality of related analyzes can be improved.

  When the analysis region includes a plurality of analysis units (analysis chips), the above-described plurality of analysis substrates may be replaced with a plurality of analysis units. That is, after reading the registration information for the first analysis unit from the registration information recording area, the analysis is performed by the second analysis unit in the same analysis board, and the new analysis is performed based on the registration information for the first analysis unit. Registration information (registration information about the second analysis unit) is recorded. Therefore, new registration information reflecting registration information related to the previous analysis can be recorded in the same analysis board, and related information can be taken over for each of a plurality of analyzes in the same board. Thereby, the convenience in performing a plurality of related analyzes can be improved.

  An embodiment of the present invention will be described below with reference to FIGS. The shape of the analysis substrate in the present embodiment may be any shape such as a plate shape, a disk shape, or a cylindrical shape, but in this embodiment, a disk-shaped analysis substrate (hereinafter abbreviated as an analysis disk). ) As an example. The analysis disk is a substrate that is expected to be used in the future because it can be measured while rotating to search a plurality of measurement cells, measurement channels, and the like on the disk at high speed.

  FIG. 1 is a plan view showing an analysis disk 1 according to an embodiment of the present invention. As shown in FIG. 1, the analysis disk 1 includes an analysis area 2, a recording area (data recording area) 3, and a dividing area (dividing part) 4. The dividing area 4 is formed in an annular shape with a narrow width, the inner area in the radial direction with respect to the dividing area 4 is the recording area 3, and the outer area is the analysis area 2.

  The dividing region 4 includes a connecting portion 4a and a cutout portion 4b. The connecting portion 4 a connects the analysis region 2 and the recording region 3, and a plurality of the connecting portions 4 a are formed in the circumferential direction of the dividing region 4. Of course, the number of connecting portions 4a is not limited. Between these connecting portions 4a and the adjacent connecting portion 4a is a notch 4b, that is, a space. Therefore, the analysis disk 1 is separated into a recording area 3 portion (recording substrate) and an analysis area 2 portion (measurement substrate) by the notch 4b, and the recording area 3 portion and the analysis region 2 portion are separated. It is connected by the connecting part 4a. The structure of the dividing region 4 is not limited to that described above. For example, the notched portion 4b is not provided, the connecting portion 4a is continuously formed in the circumferential direction, and the thickness of the connecting portion 4a is determined according to the analysis region 2 or the recording region. The analysis area 2 and the recording area 3 may be easily separated from each other by reducing the thickness of the substrate 3.

  The connecting portion 4a can be easily cut with a blade such as a cutter, and by this cutting, the analysis disk 1 can be separated into the analysis area 2 and the recording area 3 as shown in FIG. It should be noted that a dedicated cutting device can be used to separate the analysis area 2 and the recording area 3. In this case, the structure of the dividing region 4 is not limited to that described above, and may be formed as a region that can be cut by the cutting device.

  In the recording area 3, a recording medium is formed, and after the analysis of the sample, the registration information described below such as analysis data and a unique code for each analysis disk described later can be recorded on the recording medium. ing. In the recording area 3, an optical recording medium similar to an ordinary optical disk (for example, a multilayer film structure) is formed as a recording medium, and tracking grooves, address information, etc. are recorded in, for example, an uneven shape. Yes. As a material of the recording medium, a dye material used for CD-R or DVD-R, a phase change material used for CD-RW, DVD-RW, or the like can be used. The tracking groove has an uneven groove shape, but a wobble pit shape may also be used.

  In order to prevent the analysis data recorded in the recording area 3 from being falsified, erasing or rewriting of the recording area 3 may be prohibited. This can be done by software or hardware techniques. In particular, if a write-once medium such as that used in a CD-R is used, a hardware prohibition function is added, so that the security function is further improved.

  The analysis region 2 includes an analysis chip (analysis unit) 5x, and can analyze the sample. The analysis chip 5x and the analysis method will be described later. In the analysis region 2, a sample other than the analysis chip 5x may be provided as long as the sample can be analyzed.

  In addition to this, on the analysis disk 1, a unique code 92b for each analysis disk is drawn in the analysis area 2. The unique code 92b indicates that drawn in the analysis area 2. That is, the analysis area 2 includes a unique code 92b for each analysis disk. As long as the unique code can identify the analysis disk 1, any code may be drawn by any method. For example, a combination of alphabets and numbers may be drawn so as to be visible. In the present embodiment, as shown in FIG. 1, for example, “FC34P086” is printed with ink. Alternatively, it may be drawn by embossing when the analysis disk 1 is molded.

  When the analysis of the sample is completed in the analysis chip 5x in the analysis region 2 using the analysis device 13 described below, analysis data indicating the analyzed result is recorded in the recording region 3. At this time, information of the unique code “FC34P086” is also recorded. Since the unique code 92b (“FC34P086”) can be visually confirmed, for example, when an analyst (operator) visually confirms this and inputs “FC34P086” from the input unit (for example, keyboard) of the analyzer 13. The input unique code may be recorded in the recording area 3 together with the analysis data. The analysis data is recorded in the data area (not shown) of the recording area 3 and the unique code is recorded in the lead-in area (registration information area) (not shown) of the recording area 3 by optical recording. The unique code 92b is drawn in the analysis area 2. Thereafter, the recording area 3 and the analysis area 2 are separated, and the recording area 3 is held by, for example, a user or patient who is an analysis target, and the analysis area 2 is stored in, for example, a storage (preferably a freezer storage) of an inspection organization. Is done. Thereafter, analysis data holders and analysis data users such as users and patients who are analysis subjects can use only the recording area 3 and use the analysis data.

  When it is desired to search for the analysis area 2 stored in the storage based on the recording area 3 held by the analysis data holder, first, the unique code “FC34P086” recorded in the recording area 3 is reproduced. Is reproduced by an analyzer having a display, and displayed on a display, for example. Next, the analysis area 2 in which the same unique code 92b (“FC34P086”) is drawn is searched from the storage. In this way, if the recording area 3 and the analysis area 2 can be collated, even if the analysis area 2 has a pathogen and is dangerously infected, it is stored in a storage box without being discarded. It is possible to find out.

  The above is an example in which the unique code 92b (“FC34P086”) is printed in the analysis area 2 with ink, or is recorded in the analysis area 2 so as to be visible by embossing. However, recording a different unique code for each analysis disk when manufacturing the analysis disk increases costs. Therefore, an example of an analysis disk provided with a drawing area 91 in which a unique code 91a can be recorded instead of the unique code 92b as follows.

  The analysis area 2 of the analysis disk 1 includes a drawing area 91 on which a recording medium capable of optical recording is formed, instead of including the unique code 92b. When the drawing area 91 is provided, the unique code 92b need not be drawn. As the recording medium material of the drawing area 91, as in the recording area 3, a dye material used for CD-R, DVD-R, etc., and a phase change used for CD-RW, DVD-RW, etc. Material is used. If the recording medium in the drawing area 91 is formed at the same time when the recording medium in the recording area 3 is formed, there is no need to print a different unique code for each analysis disk, and the manufacturing cost can be reduced.

  When the drawing area 91 is in the analysis disk 1, the unique code is first output from the unique code generation circuit 71 of the analyzer 13 described later after the analysis is completed. Here, it is assumed that this unique code is “FC34P086” as described above. Then, the unique code “FC34P086” is recorded in the recording area 3 together with the analysis data. Further, “FC34P086” is drawn in the drawing area 91 in the analysis area 2 as the unique code 92a. It is necessary to make the reflectance or transmittance of the recording medium different between the drawn portion of the drawn unique code 92a (“FC34P086”) and the other non-drawn portions. In this case, the unique code 92a (“FC34P086”) can be visually confirmed by the difference in reflectance and transmittance. When the unique code 92a is drawn, the recording area 3 and the analysis area 2 are separated and stored as described above. Since the collation method of the recording area 3 and the analysis area 2 has been described above, the description thereof is omitted.

  If the recording medium in the drawing area 91 is the same medium as the additional recording type CD-R or DVD-R that is not rewritable, the unique code 92a is prevented from being rewritten and the collation reliability is improved. For example, the unique code 92 a (“FC34P086”) is recorded in the drawing area 91. Deliberately trying to rewrite to a new unique code (for example, “UI81R253”), the drawing area 91 is an additional recordable medium that cannot be rewritten, so the previous unique code 92a (“FC34P086”) remains. There remains evidence that the rewriting was forcibly performed. Further, even when the unique code 92a (“FC34P086”) is erased, the erased trace can be clearly seen by the difference in transmittance and reflectance. Therefore, rewriting and erasing of the unique code can be confirmed. Therefore, falsification of the analysis area 2 can be prevented. Further, even if only the recording area 3 is forged, the forgery becomes clear by collation with the analysis area 2, so that the recording area 3 can be prevented from being impersonated.

  Next, the analysis apparatus 13 for recording the unique code 92a in the drawing area 91 will be described with reference to FIG. Here, generation (output) and recording operations of the unique code will be described, and other operations will be described later. Since this analyzer 13 is a system that uses a disk-shaped analysis substrate, if the analysis substrate is a plate shape or a cylindrical shape, the device configuration is suitable for it.

  FIG. 3 is a block diagram showing a main part of the analyzer 13. The analysis device 13 includes a unique code generation circuit 71 (identification information output means). The unique code generation circuit 71 includes a random number generation circuit therein, and generates a unique code based on the random number. Therefore, the generated unique code changes every time, and the analysis disk 1 is prevented from being falsified. A command signal m for generating a unique code is sent from the controller 56 to the unique code generating circuit 71 in accordance with a flowchart to be described later. In response to this, the unique code generation circuit 71 returns the unique code n to the controller 56. After the end of the analysis operation, the controller 56 outputs the unique code n to the data recording / reproducing circuit 54, and this unique code n is recorded on the analysis disk 1 by the optical pickup 7 together with the analysis data. The analysis data is recorded in the data area of the recording area 3. The unique code “FC34P086” is recorded as registration information in a registration information recording area (for example, a lead-in area). Further, the unique code is drawn so as to be visible in the drawing area 91 of the analysis area 2. As described above, the unique code n generated on the basis of the random number in the unique code generation circuit 71 is recorded in the lead-in area of the recording area 3 and drawn in the drawing area 91 of the analysis area 2, so that it is divided. Can be matched with each other. The description of other parts in this apparatus will be described later, and the flow of the recording operation of the unique code will be described below.

  FIG. 4 is a flowchart showing an operation flow when the unique code 92a is recorded in the drawing area 91 by the analyzer 13 equipped with the unique code generation circuit 71. FIG. 4 is a diagram for explaining in detail a part of FIG. 8 showing the flow of the operation of the entire analyzer 13. Since the operation of the entire analyzer 13 will be described later with reference to FIG. 8, only the unique code recording operation (step 27, hereinafter referred to as S27) will be described here.

  In the analyzer 13, when all the analysis operations are completed and the analysis disk 1 is used, a used display is performed (S17 in FIG. 8). Thereafter, the unique code recording operation is started (S27 in FIGS. 8 and 4). In FIG. 4, when the recording operation of the unique code is started (S20), the unique code generation circuit 71 first generates a unique code based on the random number (S21). Next, the pickup is moved to the analysis area (S22). The generated unique code is drawn and recorded in the display area in the analysis area (S23). The pickup is moved to the recording area (S24). The unique code and unique code drawing end information are recorded in the lead-in area (registered information recording area) in the recording area (S25). The recording of the unique code is terminated (S26). Since the analysis area and the recording area can be separated, a separation display for instructing separation to the user of the analyzer 13 is performed on the display unit (not shown) (S18 in FIG. 8).

  As described above, the analysis area 2 of the analysis disk 1 includes the drawing area 91, and a recording medium capable of optical recording is formed in the drawing area 91. If a unique code for each analysis disk is recorded in this drawing area, the analysis area and the recording area can be collated. Furthermore, since it is not necessary to record a unique code by embossing or the like when manufacturing the analysis disk 1, the manufacturing cost of the analysis disk 1 can be reduced.

  Further, the analysis device 13 includes a unique code generation circuit 71 that generates a unique code, and can record the unique code in the recording area 3 and draw the unique code in the drawing area 91. Therefore, even after the analysis area 2 and the recording area 3 are divided, the analysis area 2 and the recording area 3 can be collated.

  In the analysis disk 1, identifiers as shown below may be used instead of the unique code 92a and the unique code 92b. As shown in FIG. 1, this identifier is printed in an area 93 extending between the analysis area 2 and the recording area 3 of the analysis disk 1 so that it can be visually verified. An enlarged view of the straddled region 93 is shown in FIG. As an example, in FIG. 5, a bar code 95 is used as an identifier instead of the unique code “FC34P086”. The reason for using the bar code is that the bar code is cut in the middle, and then the cut bars are put together so that the identifier can be easily confirmed visually. Of course, the identifier is not limited to a barcode.

  First, the barcode 95 is printed in a state where the analysis area 2 and the recording area 3 are connected by the connecting portion 4a. As shown in FIG. 5, each bar forming the barcode 95 is printed across the analysis area 2 and the recording area 3 in the longitudinal direction of the bar. After the analysis of the sample is completed and the analysis data is recorded in the recording area 3, when the analysis area 2 and the recording area 3 are separated, the bar code 95 is connected to the connecting portion 4a and the notch portion 4b in the dividing region 4. Is cut almost in the middle. If the analysis area 2 and the recording area 3 are to be collated after the analysis area 2 and the recording area 3 are separated, the same barcode 95 can be visually observed if the analysis area 2 and the recording area 3 are matched to each other. It can be verified by checking whether or not. In addition, alphabets and numbers may be recorded across the area 93. Further, the present invention is not limited to this, and a unique pattern may be used. In order to record over both areas, for example, printing is performed by an ink jet printer. According to the printing method, the unique code can be drawn at a low cost at high speed on each analysis disk.

  In this embodiment, a unique code is provided in the analysis area 2 and a unique code is recorded in the recording area 3. That is, in the present embodiment, both the analysis area and the recording area are provided with association information (in this embodiment, a unique code) that can be collated with the other, but at least one area has the other It is only necessary to provide association information that can be compared with the area. Then, after the analysis area and the recording area are divided, it is possible to easily collate each other.

  Here, the association information may be any information as long as it can be collated with the other area in the analysis area and the recording area, and either the analysis area or the recording area. May be provided, or both regions may be provided. Further, when both areas are provided, the association information of both areas may be the same information or different information. In addition, the association information can be collated more easily if it is visible, for example. Note that “comprising” may be an aspect recorded in an area by printing or processing, or an aspect in which a seal or the like is affixed to the area. Further, for example, the dividing portion connecting the analysis area and the recording area may be cut off in a unique shape for each analysis substrate, and then fitted together so that collation can be performed. Here, the separated shape is the “association information”. In addition, since each analysis board is cut off in a unique shape, it means that “the association information is provided”.

  The analysis area of the analysis disk 1 and other configurations of the analysis device 13 will be described in detail below.

  In FIG. 1, the analysis region 2 of the analysis disk includes a plurality of analysis chips 5x, 5x,... Arranged radially from the center of the analysis disk 1. In addition, the analysis region 2 may be provided with another flow path for performing electrophoresis or chromatography, for example, as long as the analysis of the sample is possible, not the analysis chip 5x. However, the present invention is not limited to these.

  In the analysis disk 1 of the present embodiment, for example, eight analysis chips 5x are mounted. The number and size are not limited. Although not shown, a number is assigned to each analysis chip 5x, and the used and unused ones of the analysis chip 5x can be distinguished by referring to the numbers.

  In the present embodiment, a case where the analysis chip 5x is an electrophoresis chip will be described as an example of the analysis chip 5x. In the electrophoresis chip, for example, DNA or protein to which fluorescent molecules are bound can be electrophoresed, and the speed of electrophoresis can be detected by irradiating with excitation light, and the mass and charge can be analyzed. Analysis data indicating the result of analysis in the analysis area 2 is recorded in the recording area 3 as described later.

  The analysis chip 5x includes liquid reservoirs 5a to 5d and a migration path 5e. The structure of the electrophoresis chip is a commonly used structure, and is disclosed in Patent Document 2 together with an analysis example, for example.

  The migration path 5e is formed in a groove shape, and includes a first migration path that extends in the radial direction of the analysis disk 1 and a second migration path that extends in a direction orthogonal to the first migration path, and these form a cross shape. Is arranged. Each of the liquid reservoirs 5a to 5d is arranged at four ends of the migration path 5e so as to communicate with the migration path 5e. That is, a liquid reservoir 5a is disposed at one end of the second migration path, a liquid reservoir 5c is disposed at the other end, a liquid reservoir 5b is disposed at one end of the first migration path, and 5d is disposed at the other end.

  The width and depth of the migration path 5e are several μm to several hundred μm, and the diameters of the liquid reservoirs 5a to 5d are several hundred μm to several mm. Such a thin migration path 5e is generally called a microchannel or a microcapillary. The migration path 5e is sealed by a cover layer as will be described later, while the liquid reservoirs 5a to 5d are exposed on the surface of the analysis disk 1 because a buffer solution and a sample solution are injected.

  In the present embodiment, electrodes (power connection wirings) 6a to 6d connected to the liquid reservoirs 5a to 5d are formed by being drawn out to the outermost peripheral part of the recording area (the outermost peripheral part of the analysis disk 1). Power for electrophoresis is supplied to the extreme part from the analyzer 13 via a connector. Specifically, the electrode 6a is connected to the liquid reservoir 5a, the electrode 6b is connected to the liquid reservoir 5b, the electrode 6c is connected to the liquid reservoir 5c, and the electrode 6d is connected to the liquid reservoir 5d.

  In the present embodiment, an example of an electrophoresis chip is shown as the analysis chip 5x included in the analysis region 2 of the analysis disk 1. However, the present invention is not limited to this, and the analysis chip 5x may include incubation, column chromatography, etc. It may be replaced with a chip.

  FIG. 6 is a perspective view showing a cross section of the migration path 5e and the liquid reservoir 5d in the analysis region 2 (which may be any liquid reservoir, but will be described here using the liquid reservoir d). In the figure, for convenience of explanation, the entire analysis chip 5x is not shown, and as a part thereof, a cross section of the migration path 5e and the liquid reservoir 5d is shown. As shown in FIG. 6, the analysis disk 1 basically has a structure in which a plastic cover layer 42 is bonded to a plastic substrate 41 with an adhesive. The thickness of the substrate 41 is 1.2 mm or 0.6 mm, and the thickness of the cover layer 42 is 0.1 mm. On the substrate 41, the migration path 5e and the liquid reservoir 5d are molded. Further, guide grooves (grooves) 43, 43,... For attracting and scanning the light beam a are formed on the substrate 41 in order to detect the analyzed band in the migration path 5e with the light beam a. Yes. For example, when the wavelength of the light beam a is 400 nm and the numerical aperture of the objective lens in the optical pickup (recording unit, reproducing unit, analyzing unit) 7 is 0.65, the guide groove 43 has a width of 400 to 600 nm. The depth is 40-50 nm. In addition, a reflective film 44 for returning reflected light to the optical pickup 7 is formed on the substrate 41 in order to perform focus servo and tracking servo of the light beam a.

  Note that the metal reflection film 44 is not formed below the migration path 5e. Therefore, the electric field for electrophoresis is not easily generated by the metal reflection film 44. When the reflective film is other than a metal, it is not necessary to consider the influence of the reflective film on the electric field, and the film formation region of the reflective film need not be limited as described above. Further, if the intensity of the reflected light is detected by the optical pickup 7, the presence or absence of the reflective film 44 can be determined. This is due to the following reason. The reflected light is strong if reflected by the reflective film 44, and weak if not reflected. Therefore, a relative difference in reflected light occurs between the region of the guide groove 43 where the reflective film 44 is present and the region of the migration path 5e where the reflective film 44 is absent. Therefore, if the reflected light is detected, the presence or absence of the analysis region 2 can be known. That is, in the analysis disc 1, when the analysis area 2 exists, a high level reflected light amount and a low level reflected light are detected depending on the presence or absence of the reflection film 44, and the analysis area 2 is separated and recorded without being present. When only the region 3 is present, the presence or absence of the analysis region 2 can be determined by detecting only the low-level reflected light amount.

  Further, not limited to the above, for example, if information indicating the presence / absence of the analysis area 2 is recorded in the recording area 3 and recorded in the registration information, the presence / absence of the analysis area 2 is determined by reading the registration information from the recording area 3. I can know. That is, it can be determined by the light beam a from the optical pickup 7 whether it is the analysis disk 1 with the analysis area 2 or the analysis disk 1 having only the recording area 3 after the analysis area 2 is separated. Therefore, it is determined whether the analysis disk 1 has been completely analyzed and no unused analysis chip 5x is present, or is the analysis disk 1 in which the analysis has not been completed and the unused analysis chip 5x remains. Can be determined. As a result, it is possible to prevent malfunction such as the analysis device 13 erroneously performing an analysis operation on the analysis disk 1 that has been analyzed, or erroneously refusing the analysis operation of the analysis disk 1 that has not been analyzed. it can. The registered information is information related to analysis, such as the analysis date and time, detailed information related to the analysis sample (sample), and the number of the analysis chip 5x used. Further, the registered information may include, for example, the name of the analysis subject, the analysis location, and the like.

  Next, the principal part of the analyzer 13 of this Embodiment is demonstrated using FIG. The analysis device 13 is a device that uses a disk-shaped substrate. For example, if the substrate is a plate shape or a cylindrical shape, the analysis device 13 has a device configuration suitable for it. The analyzer 13 includes an optical pickup 7, a connector 9, a data recording / reproducing circuit 54, a servo circuit 55, a controller 56, a light amount detection circuit 57, a memory 58, an electrophoresis power supply circuit 59, and a unique code generation circuit 71.

  As shown in FIG. 3, the optical pickup 7 includes an optical pickup main part 51, an objective lens 52, and an objective lens actuator 53. The optical pickup main part 51 irradiates the analysis disk 1 with a laser beam emitted from a semiconductor laser such as a semiconductor laser, a collimating lens, a beam splitter and a photodetector (not shown) via the objective lens 52 and also through the objective lens 52. A known configuration for obtaining a reproduction signal based on the reflected light from the incident analysis disk 1 is provided.

  The light beam a emitted from the semiconductor laser of the main part 51 of the optical pickup is condensed on the analysis disk 1 by the objective lens 52 in the optical pickup. Focusing servo is performed so that the focused spot is focused on the reflective film 44 in the analysis region 2. As a result, the light beam a is guided to the tracking guide groove 43 to access a desired detection position on the migration path 5e and is scanned. In addition, since the reflecting film 44 and the bottom surface of the migration path 5e are substantially in the same plane, the focusing path 5e can be focused, and highly sensitive analysis and detection are possible.

  In the recording area 3, a recording medium 60 is formed instead of the reflection film 44, and the light beam a is focused on the recording medium 60, and high-density data recording is possible. In the recording area 3, a guide groove (not shown) similar to the guide groove 43 is formed. The technique of recording / reproducing while tracking the guide groove is within the scope of the conventional optical disk technique and is well known, so the description thereof is omitted.

  The reflected light from the analysis disk 1 is converted into an electrical signal by the photodetector of the optical pickup main part 51. This photo detector includes a well-known servo division detector and an information reading detector. The output signal b of the servo division detector is sent to the servo circuit 55, and the error signal h is fed back to the objective lens actuator 53 in order to perform focus servo and tracking servo. The output signal j of the detector for reading information is an electric signal obtained by converting the amount of light detected in the electrophoresis band when the light beam a scans the analysis region 2, and is sent to the light amount detection circuit 57 to be analyzed data d. Is sent to the memory 58 for storage. The output signal j is a signal obtained by reading analysis data and other registration information recorded in the recording area 3 when the light beam a scans the recording area, and is input to the data recording / reproducing circuit 54. The reproduction data and registration information e are sent to the controller (output means) 56. When recording analysis data or registration information, a recording signal c is sent from the data recording / reproducing circuit 54 to the main part 51 of the optical pickup, and a recording laser pulse (light beam a) is sent from the built-in semiconductor laser to the analysis disk 1. The recording area is irradiated and recording is performed.

  The controller 56 performs various controls as follows. First, analysis data is output as will be described later while exchanging command signals and stored data k with the memory 58. Further, the controller 56 outputs a command signal f to the electrophoretic power supply circuit 59, whereby the electrophoretic power supply circuit 59 sends the power supply voltage i to the connector 9, and the power supply voltage is supplied to the liquid reservoir as shown in FIG. i is supplied to control the electrophoresis process. Further, the command signal e is sent to the data recording / reproducing circuit 54 to reproduce the analysis data and registration information stored in the recording area 3 and record the analysis data stored in the memory 58 in the recording area 3. Further, it also serves as an output means for outputting the number of the unused analysis chip 5x according to the reproduced registration information. Further, the unused analysis chip 5x is validated according to the registration information, and also serves as a control means for starting the analysis. Further, a command signal g is sent to the servo circuit, and the light beam a is accessed to an appropriate track in the recording area 3.

  Further, at the time of analysis, the controller 56 accesses the light beam a to a desired detection position of the migration path 5e in the analysis region 2 and detects analysis data. At this time, it also serves as means for determining in advance whether the analysis area 2 remains connected to the analysis disk 1 or only the recording area 3 is cut off based on the reflected light amount signal to the optical pickup 7. The description of this operation is omitted because it has been described above using detection of reflected light from the reflective film 44 in FIG.

  An analysis process for analyzing a sample using the analyzer 13 having the above configuration will be described. First, the buffer solution is injected into the liquid reservoirs 5a to 5d shown in FIG. 1 so that bubbles do not enter, and then the sample solution (solution in which the sample to be analyzed is dissolved) is injected into the liquid reservoir 5a. The injection of the buffer solution sample solution may be performed by an analyst (measuring person) or may be automated and performed under the control of the controller 56. 7 is connected to the electrode 6c from the power cord 10 and the connector 9 shown in FIG. 7, and the electrode 6a is connected to the ground. At this time, the electrode 6b and the electrode 6d are kept open. As a result, a positive voltage (several tens to several hundred volts) is applied to the liquid reservoir 5c, zero volts is applied to the liquid reservoir 5a, and the injected sample (sample, for example, DNA) is transferred to the migration path 5e (microcapillary). The inside migrates from the liquid reservoir 5a toward the liquid reservoir 5c.

  Next, when the sample (for example, DNA) contained in the sample solution reaches the crossing point of the cross in the migration path 5e, the electrode 6d is connected to a + voltage power source (several tens to several kilovolts), and the electrode 6b is connected to the ground. The electrodes 6a and 6c are opened. Therefore, the electrode for electrophoresis is switched from the electrode 6a and the electrode 6c to the electrode 6b and the electrode 6d. As a result, a positive voltage (several tens to several kilovolts) is applied to the liquid reservoir 5d, zero volts is applied to the liquid reservoir 5b, and the injected sample moves through the migration path 5e from the liquid reservoir 5b toward the liquid reservoir 5d. Run. Since the principle of electrophoretic measurement using such a microcapillary is well known, detailed description is omitted. Note that the application of voltage is performed under the control of the controller 56.

  When the electrophoresis is completed in the analysis region 2, the optical pickup 7 provided in the analysis device 13 in FIG. 3 moves to the analysis region 2 of the analysis disk 1, and detection of the migrated band is performed by the light beam (laser beam) a. Do. The sample is usually bound with fluorescent molecules, emitted by a light source such as a laser beam, and separated and detected by a wavelength selection filter in the main part 51 of the optical pickup. The detected data is stored in the memory 58 as will be described later, and the analysis process ends.

  In the analyzer 13, when the analysis process is completed, the recording process is started. In this case, the optical pickup 7 moves to the recording area 3 and records the analysis data in the recording area 3 by the light beam a. At this time, registration information such as the analysis date and time, detailed information about the sample, and the number of the analysis chip 5x used is added and recorded together. For example, when a regular analysis (periodic inspection) is performed on the blood of a single analysis subject (subject), the results of periodic diagnosis for eight times are sequentially recorded in the recording area 3. When eight periodic inspections are completed, there is no unused analysis chip 5x. Therefore, the analysis area 2 is not required in the analysis disk 1, and only the recording area 3 needs to be stored.

  As shown in FIG. 2, the analysis area 2 that is no longer needed is separated from the recording area 3 by cutting the connecting portion 4 a in the dividing area 4. Note that the drawing area 91 is omitted. This separation operation may be performed manually or using a dedicated separation device.

  The overall diameter of the analysis disk 1 (the diameter including the analysis area 2) is 12 cm, which is a size that complies with the standard of a compact disk or digital video disk, and the diameter of the recording area 3 (after being separated from the analysis area 2). If the diameter is set to 8 cm, which is a small diameter size of the same standard, a small diameter size storage disk (recording area 3) on which analysis data is recorded can be reproduced on a commercially available CD-ROM device or DVD-ROM device. The property is further improved. Further, since the storage disk (recording area 3) is small in size, it is suitable for carrying and storage.

  When the above analysis disk 1 is used, if the above diagnostic analysis spreads widely to general households as well as specialized inspection institutions, the patient who is the subject of the analysis and the caregiver himself / herself periodically analyze it at home. It is possible to bring only a small-diameter disk, which is the result of eight regular examinations, to the hospital and receive a diagnosis, and the physical and psychological burdens of the patient and caregiver who are the analysis target can be greatly reduced.

  In analyzing the sample and recording data, the analysis disk 1 is placed on a turntable and rotated. The turntable 11 will be described. FIG. 7 is a perspective view showing the main part of the turntable 11 with the analysis disk 1 mounted in the analyzer 13. The analysis disk 1 is placed on the turntable 11 and fixed to the turntable 11 by connectors 9, 9,. Although only three connectors 9 are shown for convenience, the same number of connectors 9 are actually mounted as the analysis chips 5x. The connector 9 is connected to the electrodes 6a to 6d drawn out and wired to the outermost peripheral portion of the analysis disk 1, and the power supply voltage i is supplied through the power cords 10, 10,. The turntable 11 is rotated by the spindle motor 12 at a predetermined rotation speed.

  Next, the analysis and recording operations performed by the analyzer 13 will be described using the flowchart of FIG. The following operation is performed under the control of the controller 56.

  When analysis of the analysis disk 1 is started by the analyzer 13 (step 1, hereinafter referred to as S1), it is first detected whether or not the analysis disk 1 includes the analysis region 2 (S2). This can be determined based on whether or not a predetermined amount of reflected light when the light beam a is applied to the reflective film 44 in the recording area 3 can be detected as described above. That is, in the analysis disk 1, when the analysis region 2 exists, a high level of reflected light and a low level of reflected light are detected depending on the presence or absence of the reflective film 44, and the analysis region 2 is separated and does not exist. When only the recording area 3 is present, the presence or absence of the analysis area 2 can be determined by detecting only the low-level reflected light amount.

  When it is detected that there is no analysis area on the analysis disc 1 and only the recording area 3 is present, that is, that the analysis area 2 is disconnected (NO in S2), the operation ends (S19).

  If the analysis area 2 exists on the analysis disk 1 (YES in S2), the optical pickup 7 is moved to the recording area 3 (S3), and the registered information is read (S4). It is determined from the registered information whether there is an unused migration path 5e (analysis chip 5x) (S5). When it is determined that there is no unused migration path 5e (analysis chip 5x) (NO in S5), a used display indicating that all analysis chips 5x are used is displayed on a display unit (not shown). (S17). Then, an instruction for separating the analysis area 2 is displayed to the analyst (S18), and the process is terminated (S19). Thereby, although there is no unused migration path 5e, it is possible to prevent a situation in which erroneous analysis data is detected by a residual sample by erroneously injecting a sample into the used migration path 5e.

  If it is determined in S5 that there is an unused migration path 5e (analysis chip 5x) (YES in S5), the number of the unused migration path 5e (analysis chip 5x) is displayed on the display unit (not shown). (S6), and a sample injection instruction is displayed (S7). The injection instruction is given to the analyst. For example, when the injection is automated, it may not be displayed. When the inspector manually injects the sample according to the sample injection instruction, electrophoresis is performed on the sample (analysis sample) (S8). At this time, a desired power supply voltage i is supplied from the electrophoresis power supply circuit 59 to the analysis chip 5x via the connector 9, and electrophoresis is performed.

  When the electrophoresis is completed, the optical pickup 7 is moved to the analysis region 2 (S9), and the fluorescent electrophoresis pattern band is detected as analysis data. In this case, for example, DNA analysis data that can be analyzed by electrophoresis is detected (S10). The analysis data is temporarily stored in the memory (S11).

  Next, the optical pickup 7 is moved to the recording area 3 (S12), and the analysis data temporarily stored in the memory 58 and the registered information such as the number of the used migration path 5e (analysis chip 5x) and the analysis date and time are stored. Recording is performed in the recording area 3 (S13). When the recording is completed, the display of the end of analysis is performed on the display unit (S14).

  Thereafter, it is determined whether or not the unused analysis chip 5x still remains (S15). If it does not remain (NO in S15), a display indicating that all the analysis chips 5x have been used is performed. (S17) After recording the unique code (S27), the recording area is separated and displayed (s18). On the other hand, if unused analysis chips 5x remain (YES in S15), the remaining number of analysis chips 5x is displayed on the display unit (S16), and the process ends (S19). The unique code recording operation (S27) is as shown in FIG.

  As described above, if the number of the unused analysis chip 5x or the used analysis chip 5x is registered in the recording area 3 as registration information together with the analysis data, the registration information reproduced in advance at the time of the next analysis. Based on the above, it is possible to validate the unused analysis chip 5x and perform the analysis process.

  For example, when the same analysis subject performs periodic inspection analysis using the analysis disk 1, based on the registered information, the analysis is performed on the unused analysis chip 5 x and the analysis data is recorded in the recording area 3. To do. In the next analysis, analysis is performed using the remaining unused analysis chip 5 x on the same analysis disk 1, and analysis data is recorded in an empty recording area 3 in the recording area 3. If this is repeated sequentially for each periodic inspection, the recording area 3 and the analysis area 2 are separated after using the entire analysis chip 5x of the analysis disk 1, and the analysis subject stores the results of the periodic inspection in the recording area 3. be able to. Furthermore, if the erasure and rewriting of the recording area 3 are prohibited, the result of the periodic inspection cannot be erased or rewritten by mistake. This erasure and rewrite prohibition operation can be performed by software or hardware. In particular, if the recording area 3 is composed of a recordable medium such as a CD-R or a DVD-R, it is hardware-like. Since the prohibition function is added, the safety of the analysis data is further improved.

  FIG. 9A is a diagram for explaining the flow necessary for the periodic inspection by replacing S6 described with reference to FIG. 8 with another step (S6 ′). FIG. 9B is a diagram for explaining the flow necessary for the periodic inspection by replacing S14 described with reference to FIG. 8 with another step (S14 ′).

  In S6 ', in addition to the display operation (S6) of the unused analysis chip 5x in FIG. 8, the patient name, examination history, and past analysis data are displayed. In S14 ', in addition to the analysis end display operation (S14) in FIG. 8, the patient name, examination history, past analysis data, and the next scheduled examination date are displayed. It should be noted that the past analysis data includes the analysis data analyzed this time. Through the processes of S6 ′ and S14 ′, the same analysis disk 1 is used in periodic inspection, analysis is performed on the remaining unused analysis chip 5x, and analysis data is recorded in an empty area in the recording area 3. By doing so, you can check the progress of the diagnosis every time. Further, after all the analysis chips 5x are used, the recording area 3 and the analysis area 2 can be separated, and the result of the periodic inspection only for the person to be analyzed can be stored in the recording area 3. The stored small-diameter disk (recording area 3) can be safely stored by the person to be analyzed and the diagnostician.

  In the present embodiment, as shown in FIG. 1, an example in which there are eight analysis chips 5x on the analysis disk 1 is shown, but the periodic inspection is not necessarily completed within eight times. That is, it does not necessarily end with one analysis disk 1. If the diagnosis exceeds eight times, the analysis data and registration information for the eight times are first copied to the recording area 3 of the second unused analysis disk 1 and then 9 times on this unused disk. The second analysis is performed and additional recording is performed in the recording area 3. At this time, in order to record that it is the ninth periodic inspection, it is necessary to record by adding 8 to the number of times. If such a number of times of recording is continued on the third and subsequent analysis discs 1, the periodic inspection can be performed until the capacity of the recording area 3 is full.

  In the periodic inspection, it is preferable to analyze one specimen and record analysis data on one analysis disk 1. This is because if analysis data of a plurality of analysis subjects is recorded on one analysis disk 1, the analysis subject himself / herself cannot store the analysis data as personal data. In the future, assuming that the patient who is the subject of analysis moves to a system that stores and manages the chart, it is necessary to analyze one sample and record analysis data on one analysis disk 1.

  When the analysis is performed using the analysis disk 1, it is confirmed whether or not the user is the person including the personal authentication data (including the name) based on the registration information. As a result, sample analysis and analysis data of an analysis subject other than the subject person are not performed.

  As described above, in the present embodiment, the analysis disk 1 including the dividing area 4 has been described. However, additional update of registered information over a plurality of analysis disks 1... And only unused analysis chips 5x based on the registered information. Control of the analysis operation and the like is effective even if the dividing area 4 is not provided.

  Moreover, the analysis substrate according to the present invention can be used not only in electrophoresis but also in other assays such as hybridization, incubation, and column chromatography.

  In this embodiment, the light beam a is applied to the migration path 5e (first migration path) as a cell. However, the light beam a may be applied not to the migration path 5e but to other shaped cells. This example will be described with reference to FIG.

  FIG. 10 is a diagram showing a structure of the analysis substrate 1a on which a small cell 81 for assay (for example, a cell for DNA hybridization) is formed. The analysis substrate 1a shown in FIG. 10 has a disk shape like the analysis disk 1, and includes an analysis area 2a, a recording area 3a, and a dividing area 4c. A large number of assay cells 81 are formed on the analysis substrate 1a instead of the migration path 5e described above. The size of each cell 81 is, for example, 10 μm to 1 mm. The size and number of cells are not particularly limited. A guide groove 82 is provided between the cells 81. Here, the analysis board 1a is also provided with address information (not shown).

  Thus, in addition to the cell 81, the analysis substrate 1a is provided with the guide groove 82 and the address information. Therefore, the analysis substrate 1a can also access the cell 81 at a desired address and irradiate the light beam a.

  In the above description, a disk-shaped analysis disk is taken as an example of the analysis substrate. However, the analysis board according to the present invention is not limited to the disk shape, and may be a card-shaped analysis card 101 as shown in FIG. The analysis card 101 includes an analysis area 102, a recording area 103, a division area 104, a drawing area 105, and an analysis cell (analysis unit) 106. The dividing region 104 includes a connecting portion 104a and a cutout portion 104b.

  The analysis region 102 is provided so that a sample can be analyzed. A large number of assay cells 106 are formed in the analysis region 102 instead of the migration path 5e described above. The size and number of each cell 106 are not limited. The recording area 103 can record data. The connection area 104 connects the analysis area 102 and the recording area 103 in the same manner as the division area 4 and includes a connection portion 104a and a notch portion 104b. The connecting portion 104 a connects the analysis region 102 and the recording region 103, and a plurality of connecting portions 104 a are formed between the analysis region 102 and the recording region 103. Of course, the number of connecting portions 104a is not limited. A notch 104b, that is, a space is formed between the connecting portion 104a and the adjacent connecting portion 104a. Therefore, the analysis card 101 is separated into the analysis area 102 and the recording area 103 by the notch 104b and is connected by the connecting part 104a. The drawing area 105 can record information (analysis card identification information) that can be collated with data recorded in the recording area.
