PROBLEM TO BE SOLVED: To provide an analysis device that can more accurately perform analyses.SOLUTION: An analysis tool A includes a housing 1 that has an insertion part 12 into which an analysis tool 8 is inserted in an x direction, and a display part 51 that is attached to the housing 1 to display information on analysis toward one side in a z direction. The housing 1 further includes a grip part 11 that guides the grip of a user on the other side in the z direction, and a temperature detection part 4 that has an exposed part exposed from the housing 1 to the other side in the z direction at a position other than the grip part 11.

Description

  The present invention relates to an analyzer for a specimen derived from a living body.

  Analysis of biological specimens is widely performed as a means for maintaining the health of living bodies including humans. FIG. 12 discloses an example of such an analyzer (see Patent Document 1). The analysis apparatus X shown in the figure performs analysis for obtaining a blood sugar level using blood collected from a human body as a sample. The analysis apparatus X has a housing 91, and a display unit 92 that displays information related to analysis is provided in the housing 91. An analysis unit 93 is attached to one end of the housing 91. The analysis unit 93 has a configuration in which a light emitting / receiving unit 93a and a temperature sensor 93b are accommodated in a cylindrical body. The light emitting / receiving unit 93a is a part that analyzes a sample spotted on a reagent (not shown) of the analysis chip 94 by an optical method. The cylindrical body is provided with an opening through which light from the light emitting / receiving portion 93a and light reflected by the analysis chip 94 pass. The temperature sensor 93b is for estimating the outside air temperature.

  The temperature at which the sample reacts with the reagent of the analysis chip 94 is greatly influenced by the outside air temperature. On the other hand, the temperature sensor 93 b for estimating the outside air temperature is housed inside the cylindrical body of the analysis unit 93. For this reason, there is a concern that the temperature sensor 93b cannot accurately detect the outside air temperature. For example, when the analyzer X is held by the user for a long time or is stored in the pocket of the user's clothes, the entire analyzer X is warmed to the body temperature of the user. On the other hand, it is assumed that the analysis chip 94 is spotted and attached to the analysis unit 93 in a state where the temperature is substantially the same as the outside air temperature. In such a case, the temperature at which the specimen reacts with the reagent is assumed to be approximately equal to the outside air temperature, but the temperature detected by the temperature sensor 93b is close to the body temperature of the user. Such a situation may impair the accuracy of the analysis result.

Note that the configuration in which the x direction, which is the first direction, and the z direction, which is the second direction, are perpendicular to each other is an example of the present invention. The first direction and the second direction are not limited to a relationship that is perpendicular to each other, and may be any direction that intersects each other, that is, different directions.

  The housing 1 is formed in a size and a shape such that a user such as a medical worker can perform an analysis operation for the hand, and is made of, for example, resin. The housing 1 accommodates an analysis unit 2 barcode reading unit 3, a temperature detection unit 4, a display unit 51, an operation button 52, a USB port 53, an RFID communication unit 54, a power supply unit 55, a control unit 6, and a storage unit 7. ing. The housing 1 has a grip part 11, an insertion part 12, a guide part 13, an opening 14, a peripheral part 15, and a plurality of gap parts 16.

  The grip part 11 is located on the opposite side to the display part 51 in the y direction, and is a part that guides the grip of the user. In the present embodiment, the grip portion 11 is configured such that a relatively wide portion near the center except the portions near both ends in the x direction of the housing 1 is recessed in the y direction. The gripping part 11 has a substantially constant cross-sectional shape in the zx plane.

  The insertion part 12 is a part into which the analysis tool 8 is inserted in the x direction. In the present embodiment, the insertion portion 12 has an opening in the x direction, and has a long rectangular shape in the x direction when the y direction corresponding to the shape of the analysis tool 8 is the longitudinal direction. The guide part 13 is for guiding the insertion of the analysis tool 8 into the insertion part 12. The guide portion 13 is provided adjacent to and immediately below the z direction of the insertion portion 12 and protrudes in the x direction. The guide portion 13 has an elongated shape along the long side of the insertion portion 12 when viewed in the x direction.

  The opening 14 is provided to expose a part of the temperature detection unit 4 to the outside of the housing 1 as an exposed part. The opening 14 is disposed on the side opposite to the display unit 51 in the y direction. The opening 14 is located between the grip portion 11 and the insertion portion 12 in the x direction. In the present embodiment, the opening 14 has a rectangular shape. The peripheral portion 15 is a portion surrounding the opening 14. That is, the surrounding portion 15 surrounds the exposed portion exposed from the opening 14 in the temperature detecting portion 4.

  The plurality of gaps 16 are provided to reduce the contact area between the housing 1 and the temperature detection unit 4 as described later.

  The analysis unit 2 performs an analysis process on a specimen derived from a living body such as blood, urine, and sweat. In the present embodiment, an example will be described in which the analysis unit 2 performs blood glucose measurement using blood collected from a patient as a sample. The analysis when blood is used as a specimen includes, for example, uric acid level measurement in addition to blood glucose level measurement. The analysis unit 2 is disposed behind the insertion unit 12 of the housing 1 in the x direction. Further, the analysis unit 2 has an electrode unit 21. The analysis tool 8 includes, for example, an electrode 81 and a spotting portion 82. The electrode 81 is a portion that is electrically connected to the analysis unit 2 by contacting the electrode unit 21 of the analysis unit 2. The spotting part 82 is a part where blood as a specimen is spotted. Furthermore, the analysis tool 8 has a wiring for connecting the electrode 81 and the spotting portion 82. The analysis tool 8 is provided with a reagent (not shown). As an aspect of this reagent, an aspect provided in the spotting portion 82 can be cited. When blood glucose level measurement is performed, the reagent includes, for example, an enzyme glucose oxidase and potassium ferricyanide as an electron acceptor. With such a configuration, the analysis unit 2 performs blood sugar level measurement processing by a known method using the blood spotted on the analysis tool 8 as a sample. In the analyzer A, the analysis tool 8 is inserted into the insertion portion 12, and then blood as a specimen is spotted on the spotting portion 82. For this reason, although the electrode 81 of the analysis tool 8 is completely accommodated in the housing 1, the spotting portion 82 is configured to protrude from the housing 1.

  The barcode reading unit 3 corresponds to an example of the information reading unit referred to in the present invention. The analysis apparatus A receives data belonging to any of a plurality of attributes accompanying the analysis processing by the analysis unit 2. Examples of the plurality of attributes include an analyst ID for identifying a medical worker, a patient ID for identifying a patient, an analysis tool ID for identifying the analysis unit, and a quality control substance used for quality control for the analysis process Quality control substance IDs for identifying IDs, and analysis process IDs for identifying individual analysis processes. In this embodiment, these data are input by the barcode reading unit 3. That is, data to be input is given as a barcode printed on a medium such as a card, wristband, packing box, paper, etc., and the barcode reading unit 3 reads these barcodes. Typical examples of the bar code here include a one-dimensional bar code composed of a plurality of striped lines and a two-dimensional code composed of a plurality of dots arranged vertically and horizontally.

  The barcode reading unit 3 includes, for example, a light emitting unit, a light receiving unit, and a driver IC. The light emitting unit emits light for reading, and emits linear light including red light, for example. The light receiving unit receives reflected light reflected by the medium with a barcode, and has a configuration in which a plurality of light receiving elements are arranged in a row or matrix. The driver IC forms image data for recognizing a barcode based on an output signal from the light receiving unit. Alternatively, the driver IC may be configured to output data converted into a barcode as digital numerical data by analyzing the image data. Further, this numerical function may be performed by the control unit 6.

  The barcode reading unit 3 is provided on the same side as the insertion unit 12 in the x direction. Further, the barcode reading unit 3 is arranged on the opposite side of the display unit 51 with respect to the insertion unit 12 in the z direction, that is, on the holding unit 11 side. More specifically, the barcode reading unit 3 includes a translucent unit provided in the housing 1. The translucent part transmits the above-described reading outgoing light and the light reflected from the medium, so that the barcode reading part 3 is placed in the x direction with respect to the housing 1. Read the information attached to the medium. For the purpose of facilitating the operation of reading the barcode, the barcode reading unit 3 may be configured to face slightly downward.

  The temperature detection unit 4 detects the temperature, and has a configuration that is particularly intended to detect the outside air temperature more accurately. In the present embodiment, the temperature detection unit 4 includes a temperature sensor 41 and a heat conductor 42. The temperature sensor 41 is an electronic component that performs a temperature detection function, and examples thereof include a thermocouple, a thermistor, and a resistance temperature detector. The heat conductor 42 functions to transmit the outside air temperature to the temperature sensor 41. The heat conductor 42 is made of metal such as stainless steel, iron, copper, and an alloy containing these as main components. In the present embodiment, the heat conductor 42 is a rectangular plate material. When the housing 1 is made of a general resin with respect to the heat conductor 42 having such a configuration, it can be said that the housing 1 is made of a material having a lower thermal conductivity than the heat conductor 42 housing 1.

  5 and 6, the heat conductor 42 is fixed to the housing 1 by means such as adhesion or insert molding in resin molding. The heat conductor 42 has an outer surface 43 and an inner surface 44. The outer surface 43 is a surface facing the outside of the analyzer A, and the inner surface 44 is a surface facing the inside of the analyzer A on the side opposite to the outer surface 43. The heat conductor 42 is fixed to the housing 1 so that the outer surface 43 is exposed from the opening 14. Thereby, in this embodiment, all the outer surfaces 43 of the temperature sensor 41 are exposed portions of the temperature detection unit 4. In a configuration in which a part of the heat conductor 42 is cut into the housing 1, a part of the outer surface 43 becomes the exposed portion.

  Further, as clearly shown in FIG. 5, the outer surface 43 of the heat conductor 42 is located on the upper side in the figure relative to the peripheral portion 15 of the housing 1 in the z direction, that is, on the side where the display unit 51 is located. ing. For this reason, in the analyzer A, the outer surface 43 of the temperature detector 4 is recessed from the peripheral portion 15 of the housing 1.

  A temperature sensor 41 is fixed to the inner surface 44 of the temperature detection unit 4. The temperature sensor 41 is fixed by adhesion, for example. As shown in FIG. 6, four gaps 16 are formed in the housing 1. These gaps 16 are arranged so as to surround the temperature sensor 41. From each gap 16, the inner surface 44 of the temperature detector 4 is exposed to the inside of the analyzer A. Thus, the contact area between the inner surface 44 of the temperature detection unit 4 and the housing 1 is reduced by the amount of the four gaps 16 provided. Further, a frame-like portion is formed in the housing 1 in order to partition the four gap portions 16. This frame-shaped part has a function of specifying the mounting position of the temperature sensor 41.

  The display unit 51 visually provides information to the user. For example, a liquid crystal display or an organic EL display having a plurality of pixels arranged in a matrix is preferably used.

  The operation button 52 is a part used for an operation for a user (analyzer) to make a decision on the operation of the analyzer A. In the present embodiment, the operation button 52 includes, for example, a direction button 52a, a direction button 52b, and an enter button 52c. The direction button 52a and the direction button 52b are for performing an operation of suggesting left and right on the display unit 51. The decision button 52c is used to perform an operation for permitting the operation and processing suggested by the display on the display unit 51.

  The USB port 53 and the RFID communication unit 54 are parts that serve as an interface between the analyzer A and other devices. Examples of other devices include a larger and multifunctional integrated measurement station or a PC installed in a hospital or clinic. The USB port 53 is a port for realizing wired data communication conforming to the USB standard. The RFID communication unit 54 is for realizing wireless short-range data communication using electromagnetic waves. The RFID communication unit 54 includes, for example, a coil antenna and a driver IC.

  The power supply unit 55 supplies power for realizing the operation of the analyzer A. The power supply unit 55 is constituted by a rechargeable lithium ion battery, for example. Further, the power supply unit 55 may be configured by a dry battery or an AC power supply connection unit.

  The controller 6 is for controlling the operation of the analyzer A, and typically comprises a CPU. The control unit 6 controls operations of the analysis unit 2, the barcode reading unit 3, the temperature detection unit 4, the display unit 51, the USB port 53, and the RFID communication unit 54 based on a program stored in the storage unit 7. In addition, the control unit 6 receives an input signal from the operation button 52. In the present embodiment, the following description is given on the assumption that the control unit 6 controls the main operation of the analyzer A, but the present invention is not limited to this. In the present embodiment, the function performed by the control unit 6 may be executed by another CPU provided in each unit such as the analysis unit 2, the barcode reading unit 3, the temperature detection unit 4, and the display unit 51. .

  The storage unit 7 has a program area 71 and a data area 72. For example, a volatile memory or a nonvolatile memory made of a silicon memory is appropriately employed. The program area 71 is an area for storing a program for realizing the operation of the analyzer A. The data area 72 stores data accompanying the analysis.

  In the present embodiment, the control unit 6 calculates the temperature based on the output from the temperature sensor 41. This detected temperature is stored in the data area 72 of the storage unit 7. The control unit 6 reads the detected temperature from the data area 72 in the analysis process using the analysis unit 2 and uses it for temperature correction in the analysis process.

  Next, an example of analysis using the analyzer A will be described below.

  In an example of analysis using the analysis apparatus A, data input processing is performed prior to analysis processing. In this data input process, the control unit 6 uses the barcode reading unit 3 to input data necessary for the analysis process or data to be attached to the analysis data based on the program stored in the program area 71. To do. For example, analyst ID, patient ID, analysis tool ID, etc. are mentioned. In the input data processing, the barcode attached to the medium is read by the barcode reading unit 3. At this time, guidance for guiding the operation of reading the barcode may be displayed on the display unit 51. The control unit 6 stores the data read by the barcode reading unit 3 in the data area 72 of the storage unit 7.

  When the necessary data is input, the control unit 6 executes analysis processing based on the program stored in the program area 71. The analyst inserts the analysis tool 8 into the insertion part 12 and drops blood as a specimen on the spotting part 82 of the analysis tool 8. At this time, the control unit 6 may display an image for guidance stored in the data area 72 on the display unit 51. The analysis unit 2 analyzes the blood sugar level of the blood spotted on the analysis tool 8. Moreover, the control part 6 performs the temperature detection by the temperature detection part 4, and estimates outside air temperature from the detected temperature. And based on this detected temperature, the blood glucose level which is an analysis result is correct | amended by a predetermined method. By the above processing, a blood glucose level is obtained as an analysis result. The control unit 6 stores the blood glucose level in the data area 72 of the storage unit 7 together with accompanying data such as an analyzer ID, a patient ID, and an analysis tool ID. At this time, the temperature detected by the temperature detection unit 4 may be stored in the data area 72 of the storage unit 7 as data accompanying the blood glucose level. Thus, the analysis by the analyzer A is completed.

  Next, the operation of the analyzer A will be described below.

  According to this embodiment, the temperature detection part 4 has the outer surface 43 as an exposed part exposed outside. This exposed portion is provided at a position avoiding the grip portion 11 of the housing 1. For this reason, it is possible to suppress the influence by a user's body temperature and to detect external temperature more correctly. Therefore, according to the analyzer A, a more accurate analysis can be performed. Further, the temperature detection unit 4 is exposed in the z direction, which is a direction intersecting the x direction, which is the direction in which the analysis tool 8 is inserted. For this reason, there exists an advantage that there is little possibility that insertion of the analytical tool 8 will be inhibited by providing the temperature detection part 4. FIG. Further, the temperature detection unit 4 is exposed on the side opposite to the display unit 51. For this reason, it is possible to secure a sufficient display area of the display unit 51 while providing the temperature detection unit 4.

  As shown in FIGS. 3 and 4, the temperature detection unit 4 is provided between the gripping unit 11 and the insertion unit 12 in the x direction, so that the outside in the vicinity of the insertion unit 12 into which the analysis tool 8 is inserted is provided. The temperature can be detected more accurately.

  As shown in FIG. 5, the outer surface 43, which is an exposed portion of the temperature detection unit 4, is provided at a position recessed in the z direction with respect to the peripheral portion 15 of the grip portion 11. Thereby, even if the user's hand holding the holding part 11 unintentionally reaches the position overlapping the temperature detection part 4, it is possible to avoid the user's hand directly touching the outer surface 43 which is the exposed part. It is. Therefore, it is suitable for preventing the user's body temperature from affecting the temperature detection result by the temperature detection unit 4.

  As shown in FIGS. 2 and 4, the barcode reading unit 3 reads information by emitting light in the x direction at a position adjacent to the insertion unit 12. Thus, the user can conveniently insert the analysis tool 8 or spot the sample in the analysis process and read the information from the barcode prior to the analysis process on the same side in the same direction. . In addition, the space for the barcode reading unit 3 can be sufficiently secured in the portion facing the x direction while providing the temperature detection unit 4.

  The outer surface 43 of the heat conductor 42 is exposed to the outside as an exposed portion, and the temperature sensor 41 is attached to the inner surface 44 of the heat conductor 42. Since the outer surface 43 is exposed, it can be expected that the temperature of the heat conductor 42 follows the outside air temperature more faithfully. Further, the temperature sensor 41 attached to the inner surface 44 can more reliably detect the temperature of the heat conductor 42. Therefore, such a configuration is preferable for the temperature detector 4 to detect the outside air temperature more accurately.

  Since the housing 1 is formed of a material having a lower thermal conductivity than the material of the heat conductor 42, the body temperature of the user holding the grip portion 11 is transmitted to the heat conductor 42 via the housing 1. Can be suppressed. In addition to this, the temperature of the heat conductor 42 can be quickly followed by the outside air temperature.

  As shown in FIG. 6, the contact area between the case 1 and the heat conductor 42 is reduced by providing the gap 16 in the case 1. Thereby, it can suppress more reliably that a user's body temperature is transmitted to the heat conductor 42 via the housing | casing 1. FIG. For example, when the analyzer A is brought into a place where the outside air temperature is remarkably different, the temperature of the casing 1 having a relatively low thermal conductivity is difficult to follow the change in the outside air temperature. According to the present embodiment, the contact area between the housing 1 and the heat conductor 42 is reduced, so that the contact with the housing 1 prevents the temperature of the heat conductor 42 from following the outside air temperature. This can be suppressed. Therefore, it is suitable for making the temperature of the heat conductor 42 quickly follow the outside air temperature.

  8 to 11 show a plurality of modifications of the analyzer A. In these drawings, the same or similar elements as those of the analysis apparatus A shown in FIGS. 1 to 7 are denoted by the same reference numerals as those in the above embodiment, and the description thereof will be omitted as appropriate. Naturally, the partial configuration of the example shown in FIGS. 1 to 7 and the plurality of modifications shown in FIGS. 8 to 11 can be combined with each other.

  In the modification shown in FIG. 8, the outer surface 43 of the temperature detection unit 4 is not provided at a position recessed with respect to the peripheral portion 15 of the housing 1, and the outer surface 43 and the peripheral portion 15 of the housing 1 are surfaces. It is a relationship. The configuration in which the outer surface 43 is recessed with respect to the peripheral portion 15 as in the example illustrated in FIG. 5 is suitable for preventing the user's body temperature from being transmitted to the heat conductor 42. Also in this example, since the temperature detection unit 4 is provided at a position avoiding the grip unit 11, an effect of suppressing the transmission of the user's body temperature to the thermal conductor 42 to some extent can be obtained.

  FIG. 9 is an example in which a part that can be recognized as the gap 16 is not provided in the housing 1. However, most of the inner surface 44 of the heat conductor 42 is exposed on the inner side of the housing 1. For this reason, it can suppress that a user's body temperature is transmitted to the heat conductor 42 via the housing | casing 1 also by such a structure. Positioning in attaching the temperature sensor 41 can be appropriately performed by using a separate positioning tool (not shown) or by attaching a positioning mark to the inner surface 44 of the heat conductor 42.

  10 and FIG. 11 is different from the example shown in FIGS. 1 to 7 in the shape of the opening 14. In the example shown in FIG. 10, the opening 14 has an elliptical shape. For this reason, the outer surface 43 of the heat conductor 42 of the temperature detection unit 4 has an elliptical region exposed. In the example shown in FIG. 11, the opening 14 has a substantially triangular shape. For this reason, a substantially triangular region is exposed on the outer surface 43 of the heat conductor 42 of the temperature detection unit 4.

  The analyzer according to the present invention is not limited to the above-described embodiment. The specific configuration of each part of the analyzer according to the present invention can be variously modified.
