Description

Specimen testing device and sample testing system

The embodiments disclosed in this specification and drawings relate to a sample testing device and a sample testing system.

A sample testing device that performs a test to detect the detection target contained in the sample is known. The detection target is collected from, for example, a body fluid component such as a runny nose. Detection targets include test substances such as adenovirus and influenza virus. For example, various tests can be performed by using a plurality of sample testing devices. The sample test device is provided with an input / output device. For example, the input / output device performs various inputs, displays and prints test results. For example, when a plurality of inspections are performed separately by a plurality of devices, input and printing are performed for each device, which is inefficient. Therefore, if the sample testing device is centrally managed by the master and the slave, it is expected that the testing efficiency will be improved.

Hereinafter, embodiments of the sample testing device and the sample testing system will be described in detail with reference to the attached drawings. The embodiment is not limited to the following embodiments. In principle, the contents described in one embodiment are similarly applied to other embodiments.

FIG. 1 is a diagram showing an example of a sample testing system 1 to which the sample testing device 10 according to the present embodiment is applied. As shown in FIG. 1, the sample testing system 1 includes a plurality of sample testing devices 10 and a biological reaction device 2.

The biological reaction device 2 is used to perform a test for detecting a detection target contained in a sample (for example, a body fluid component such as a runny nose). Details of the biological reaction device 2 will be described later. The biological reaction device 2 is an example of a “device”.

As shown in FIG. 1, the sample testing device 10 includes a cover 20, a main body 30, and an indicator 35.

The cover 20 is provided so as to be openable and closable with respect to the sample testing device 10. Specifically, the main body 30 is provided with a table for mounting the biological reaction device 2, and the cover 20 is provided to cover the table. For example, when performing an inspection to detect a detection target, the biological reaction device 2 is attached to the base of the main body 30, and the base is covered with the cover 20. Here, the case where the cover 20 is provided to be openable and closable with respect to the sample test device 10 is taken as an example, but the cover 20 may be provided to be detachably provided with respect to the sample test device 10.

The indicator 35 is provided on the front surface of the main body 30. The indicator 35 will be described later.

In FIG. 1, the plurality of sample testing devices 10 are composed of, for example,

sample testing devices

10A, 10B, and 10C. Of the

sample test devices

10A, 10B, and 10C, the sample test device 10A is the master sample test device 10, and the

sample test devices

10B and 10C are slave sample test devices 10. The sample test device 10A is communicably connected to the

sample test devices

10B and 10C via a network. The

sample testing devices

10A, 10B, and 10C are connected to, for example, an in-hospital LAN (Local Area Network) installed in a hospital or the like to transmit and receive information. For example, it is assumed that the

sample testing devices

10B and 10C are installed in the laboratory in which the sample testing device 10A is installed by additional purchase.

Here, as shown in FIG. 1, the sample test device 10A, which is the master sample test device 10, is provided with the input / output device 40. Since the input / output device 40 has a display, a printer, and the like described later, the cost is high. Therefore, it is preferable that the

sample test devices

10B and 10C, which are the slave sample test devices 10, are not provided with the input / output device 40 from the viewpoint of cost. The input / output device 40 is an example of an “input / output unit”.

Next, the biological reaction device 2 mounted on the base of the main body 30 of the sample testing device 10 will be described. FIG. 2 is a diagram showing an example of the configuration of the biological reaction device 2 shown in FIG.

As shown in FIG. 2, the biological reaction device 2 is mounted on a mounting table 4 which is a table of the main body 30, and has a housing 21, a transparent substrate 22, an optical waveguide 23, and a protective member 24. A part of the lower surface of the housing 21 is open, and a chip in which the optical waveguide 23 and the protective member 24 are formed by thin film technology is fitted on the transparent substrate 22 in the opening. A part of the protective member 24 is open (open end 24a). Further, the reaction vessel 201 is formed by the housing 21, the optical waveguide 23, the protective member 24, and the like. The biological reaction device 2 is configured to be capable of accommodating a sample solution containing a test object (test substance) inside the reaction container 201.

The housing 21 is made of, for example, resin or the like. A first recess is formed on the lower surface of the housing 21. A second recess forming the upper surface and the side surface of the reaction vessel 201 is formed on a part of the upper surface of the first recess. A protective member 24, an optical waveguide 23, and a transparent substrate 22 are arranged in the first recess in this order from the top. Further, a hole 21a for introducing a sample solution, a reagent, or the like is formed in the reaction vessel 201 inside the housing 21 so as to penetrate upward near one end of the upper surface of the second recess, and near the other end. A hole 21b is formed so as to penetrate the housing 21 upward and allow air to escape from the reaction vessel 201. A plurality of

holes

21a and 21b may be formed.

The transparent substrate 22 is formed of, for example, resin or optical glass. The transparent substrate 22 allows light incident from the light source 311 provided in the main body 30 to pass through the optical waveguide 23. Further, the transparent substrate 22 allows the light incident from the optical waveguide 23 to pass through the photodetector 312 provided in the main body 30.

The optical waveguide 23 is formed of a material that allows light to pass through, such as resin or optical glass. As the resin, for example, a phenol resin, an epoxy resin, an acrylic resin or the like can be used. The optical waveguide 23 serves as an optical path for light incident from the transparent substrate 22 and emitted to the transparent substrate 22. That is, the optical waveguide 23 fulfills the same role and function as the core (core material) in the optical fiber. The protective member 24 and the transparent substrate 22 are formed of a material having a refractive index different from that of the optical waveguide 23, totally reflect light at the interface with the optical waveguide 23, and confine the light in the optical waveguide 23. It functions as a clad. Further, the protective member 24 and the transparent substrate 22 physically protect the optical waveguide 23.

The optical waveguide 23 propagates the light incident from the main body 30 through the transparent substrate 22. In the optical waveguide 23, light affected by the concentration of the test substance contained in the reaction vessel 201, that is, the reaction state is propagated.

Further, a grating 23a is arranged on the protective member 24 side near the light incident on the optical waveguide 23. The grating 23a diffracts the incident light L1 incident on the optical waveguide 23 at a predetermined angle. The light diffracted in the grating 23a is incident on the interface between the optical waveguide 23 and the surface composed of the transparent substrate 22, the protective member 24, or the mixture 202 at an angle equal to or less than the complementary angle of the critical angle. As a result, the incident light L1 propagates (waveguides) while being repeatedly reflected in the optical waveguide 23 at the interface of the optical waveguide 23.

A grating 23b is arranged on the protective member 24 side near the light emitted from the optical waveguide 23. The grating 23b diffracts the light optical waveguided by the optical waveguide 23 at a predetermined angle. The light diffracted by the grating 23b is emitted from the optical waveguide 23 to the outside at a predetermined angle.

The protective member 24 has an opening at the position of the second recess of the housing 21. The protective member 24 is arranged in close contact with the upper surface of the optical waveguide 23. The protective member 24 is arranged in close contact with the upper surface of the optical waveguide 23 to form a plane protective layer. Further, as shown in FIG. 2, the protective member 24 has an opening end 24a for exposing the main surface (for example, the upper surface) of the optical waveguide 23. The opening end 24a is a vertical surface that forms an opening inside the protective member 24. The upper surface of the optical waveguide 23 is exposed by the open end 24a.

The upper surface of the reaction vessel 201 is composed of the upper surface of the second recess of the housing 21, the side surface is composed of the side surface of the second recess of the housing 21 and the open end 24a of the protective member 24, and the lower surface is the optical waveguide 23. It is composed of the upper surface of.

The reaction vessel 201 contains the sample solution and the reagent, and reacts the test substance contained in the sample solution with the reagent. A plurality of first antibodies 211 are immobilized on the lower surface of the surface forming the reaction vessel 201, that is, the upper surface of the optical waveguide 23. The first antibody 211 is a substance that specifically reacts with the antigen 212 contained in the test substance by an antigen-antibody reaction. The first antibody 211 is fixed to the upper surface of the optical waveguide 23 by, for example, a hydrophobic interaction or a chemical bond that occurs with the upper surface of the optical waveguide 23.

The reaction vessel 201 is, for example, empty in advance. At the time of measuring the test substance, for example, the mixed solution 202 of the sample solution and the reagent is injected into the reaction vessel 201 from the outside through the hole 21a. The sample solution contains a test substance containing the antigen 212. The reagent includes reagent component 213. The reagent component 213 includes, for example, a second antibody 214 that specifically reacts with the antigen 212 by an antigen-antibody reaction, and magnetic particles 215 to which the second antibody 214 is bound. At least a part of the magnetic particles 215 is formed of a magnetic material such as magnetite. In the magnetic particles 215, for example, the surface of particles formed from a magnetic material is coated with a polymer material. The magnetic particles 215 may be configured to cover the surface of the particles made of a polymer material with a magnetic material. Further, the magnetic particles 215 may be replaced with any magnetic particles 215 as long as they are dispersible in the mixed liquid 202.

By injecting the mixed solution 202, in addition to the first antibody 211 fixed on the upper surface of the optical waveguide 23, the antigen 212 contained in the test substance in the sample solution and the reagent contained in the reagent are injected into the reaction vessel 201. Ingredients 213 are housed. When the mixed solution 202 is injected into the reaction vessel 201, the air in the reaction vessel 201 is discharged to the outside through the holes 21b.

The reagent component 213 moves in a dispersible manner in the mixed solution 202 filled in the reaction vessel 201. At this time, the magnetic particles 215 are selected so that the gravity applied to the magnetic particles 215 is larger than the buoyancy in the mixture 202 applied in the direction opposite to the gravity. The magnetic particles 215 to which the second antibody 214 is bound are fixed near the upper surface of the optical waveguide 23 by binding the second antibody 214 to the first antibody 211 via the antigen 212. The second antibody 214 may be the same as or different from the first antibody 211.

In the biological reaction device 2, the first antibody 211 fixed on the upper surface of the optical waveguide 23 reacts with the antigen 212 contained in the test substance, so that the magnetic particles 215 to which the second antibody 214 is bound are formed in the optical waveguide 23. It is fixed near the top surface. The light guided through the optical waveguide 23 is scattered and absorbed by the magnetic particles 215 fixed in the vicinity of the upper surface of the optical waveguide 23. As a result, the light guided through the optical waveguide 23 is attenuated and emitted from the optical waveguide 23. That is, the incident light L1 is attenuated according to the amount of the antigen 212 that binds the first antibody 211 and the second antibody 214 immobilized on the magnetic particles 215. In other words, the incident light L1 is attenuated according to the amount of antigen 212 contained in the reaction vessel 201.

Hereinafter, in the reaction vessel 201, a region separated by a distance L in the vertical upward direction from the surface of the optical waveguide 23, that is, a region near the surface of the optical waveguide 23 is defined as a sensing area 205.

When light propagates in the optical waveguide 23, near-field light (hereinafter referred to as evanescent light) is generated on the upper surface of the optical waveguide 23. The sensing area 205 is an area where evanescent light can be generated. In the sensing area 205, the first antibody 211 immobilized on the upper surface of the optical waveguide 23 is immobilized on the magnetic particles 215 contained in the reagent component 213 via the antigen 212 contained in the test substance in the sample solution. 2 Binds to antibody 214. As a result, the magnetic particles 215 to which the second antibody 214 is bound are held in the vicinity of the upper surface of the optical waveguide 23.

Next, the influence of the light propagating on the optical waveguide 23 due to the antigen-antibody reaction or the like occurring in the reaction vessel 201 will be described. The first antibody 211, the second antibody 214, and the antigen 212 are very small as compared with the magnetic particles 215. In FIG. 2, in order to schematically show the binding reaction, the first antibody 211, the antigen 212, the second antibody 214, and the magnetic particles 215 are shown as having the same size.

When the magnetic particles 215 enter the sensing area 205, the second antibody 214 immobilized on the magnetic particles 215 binds to the first antibody 211 immobilized on the upper surface of the optical waveguide 23 via the antigen 212. As a result, the magnetic particles 215 to which the second antibody 214 is bound remain in the sensing area 205. When evanescent light is generated on the upper surface of the optical waveguide 23 while the magnetic particles 215 remain in the sensing area 205, the magnetic particles 215 remaining in the sensing area 205 scatter and absorb the evanescent light, and attenuate the evanescent light. .. Scattering and absorption of evanescent light in the sensing area 205 affects the light propagating in the optical waveguide 23. That is, as the evanescent light is attenuated in the sensing area 205, the light optical waveguided in the optical waveguide 23 is also attenuated. Therefore, when the evanescent light is strongly scattered and absorbed in the sensing area 205, the intensity of the light propagating in the optical waveguide 23 decreases. In other words, the greater the amount of magnetic particles 215 that remain in the sensing area 205, the lower the intensity of the light output from the optical waveguide 23.

However, the magnetic particles 215 remaining in the sensing area 205 include the first antibody 211 immobilized on the upper surface of the optical waveguide 23 via the antigen 212 to be measured and the second antibody 214 immobilized on the magnetic particles 215. Is not limited to the combination of. Therefore, in order to measure the accurate concentration of the antigen 212 contained in the test substance, the magnetic particles 215 to which the second antibody 214 that is not involved in the measurement, that is, that is not bound to the antigen 212, is bound is measured in the sensing area 205. You need to stay away from it. As a specific method, for example, there is a method of moving the magnetic particles 215 in which the second antibody 214 is not bound to the antigen 212 by the proximity action by a magnetic field.

As a result, the magnetic particles 215 finally staying in the sensing area 205 are bound to the first antibody 211 fixed on the upper surface of the optical waveguide 23 via the antigen 212 and the second antibody 214. Therefore, the value of the intensity of the light emitted from the biological reaction device 2 and the time-series change in the intensity correspond to the amount and concentration of the magnetic particles 215 remaining in the sensing area 205.

The biological reaction device 2 may have a configuration capable of simultaneously measuring the same test substance on a plurality of channels in parallel for the same measurement item. At this time, the biological reaction device 2 has, for example, an independent optical waveguide for each channel.

Next, the sample testing device 10A, which is the master sample testing device 10, will be described. FIG. 3 is a block diagram showing an example of the configuration of the sample testing device 10A according to the present embodiment.

First, the configuration of the input / output device 40 of the sample test device 10A will be described. The input / output device 40 is mounted on the upper surface of the sample test device 10A, and includes an output device 41 and an input device 42.

The output device 41 has a display 411 and a printer 412. For example, in FIG. 1, the front surface of the input / output device 40 of the sample test device 10A is inclined so that the user can easily see the display 411.

Display 411 displays various information. For example, the display 411 displays various images generated by the processing circuit 34 described later, and displays a GUI (Graphical User Interface) for accepting various operations from the user. For example, the display 411 is a liquid crystal display, an OLED (Organic Light Emitting Diode) display, a CRT (Cathode Ray Tube) display, or the like. The display 411 follows the control of the processing circuit 34 described later, for example, various operation screens, information indicating the light intensity of the emitted light L2 supplied from the photodetector 312 described later, time-series data of information indicating the light intensity, and , Display information about inspection. Information about the test includes, for example, the test result of the test. The test result is, for example, the amount (concentration, weight, number, etc.) or presence / absence of the antigen 212. The display 411 is an example of a “display unit”.

Under the control of the processing circuit 34 described later, the printer 412 has various operation screens displayed on the display 411, for example, information indicating the light intensity of the emitted light L2 supplied from the photodetector 312 described later, and information indicating the light intensity. Print out the time-series data of the above and the test results of the test substance. The printer 412 is an example of a "printing unit".

The input device 42 is realized by, for example, a trackball, a switch, a button, a mouse, a keyboard, a touch pad that performs an input operation by touching an operation surface, a touch panel display in which a display screen and a touch pad are integrated, and the like. The input device 42 outputs an operation input signal corresponding to the user's operation to the processing circuit 34 described later. In this embodiment, the input interface circuit is not limited to the one provided with physical operating parts such as a mouse and a keyboard. For example, an electric signal processing circuit that receives an electric signal corresponding to an input operation from an external input device provided separately from the device and outputs this electric signal to a processing circuit 34 described later is also an example of an input interface circuit. included. The input device 42 is an example of an “input unit”.

Next, the configuration of the main body 30 of the sample testing device 10A will be described.

The main body 30 has a detection unit 31 as shown in FIG. The detection unit 31 includes a light source 311 and a photodetector 312, and a reader 313.

The light source 311 is, for example, a diode such as an LED (Light Emitting Diode) or a lamp such as a xenon lamp. The light source 311 is arranged at a position where light can be incident in the optical waveguide 23 toward the grating 23a shown in FIG. The light source 311 incidents the incident light L1 into the optical waveguide 23 via the transparent substrate 22 of the biological reaction device 2.

The photodetector 312 outputs an electric signal based on the reaction state in the reaction vessel 201 containing the mixed liquid 202. Specifically, the photodetector 312 detects the emitted light L2 emitted to the outside of the optical waveguide 23, and generates an electric signal indicating the intensity of the detected emitted light L2, that is, digital data regarding the light detection intensity. .. The digital data regarding the light detection intensity generated by the photodetector 312 is supplied to the processing circuit 34 described later.

The detection unit 31 may have a configuration capable of simultaneously measuring the same test substance on a plurality of channels in parallel for the same measurement item. At this time, the detection unit 31 may have a light source and a photodetector for each channel, for example, or may share the light source and the photodetector.

Further, the detection unit 31 has a detector that detects the opening / closing of the cover 20 with respect to the main body 30. When the detector detects that the cover 20 has been opened from the main body 30, it outputs information indicating that the cover 20 has been opened to the processing circuit 34, and the cover 20 is closed by the main body 30. When this is detected, information indicating that the cover 20 has been closed is output to the processing circuit 34.

The reading device 313 reads the type of the detection target from the identifier provided in the biological reaction device 2, and outputs the reading information indicating the type of the biological reaction device 2 to the processing circuit 34. Specifically, an identifier that identifies the type of the biological reaction device 2 is provided on the back surface of the biological reaction device 2. For example, when a test substance containing an antigen 212 such as virus A or virus B is targeted for detection, the type of biological reaction device 2 is a biological reaction device 2 for virus A test or a biological reaction device for virus B test. 2 and so on. For example, a QR code (registered trademark) 2a that identifies the type of the biological reaction device 2 is printed on the back surface of the biological reaction device 2. When the biological reaction device 2 is mounted on the mounting base 4 of the main body 30, the reading device 313 reads the type of the biological reaction device 2 from the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2. , The reading information indicating the type of the biological reaction device 2 is output to the processing circuit 34.

For example, the types of detection targets are color-coded, and green and blue are assigned to the biological reaction devices 2 for virus A and virus B inspection, respectively. Specifically, the biological reaction device 2 for virus A test and the package of the reagent to react with the biological reaction device 2 are color-coded in green. Similarly, the biological reaction device 2 for virus B inspection, the package of the reagent to react with the biological reaction device 2, and the like are color-coded in blue.

Here, in the present embodiment, the QR code (registered trademark) 2a is used as an identifier for identifying the type of the biological reaction device 2, but the present invention is not limited to this, and for example, a barcode or the like may be used.

As shown in FIG. 3, the main body 30 further includes a magnetic field generator 32, a storage circuit 33, and a processing circuit 34.

The magnetic field generator 32 is mediated by the reaction in the reaction vessel 201 shown in FIG. 2, that is, the antigen 212 of the second antibody 214 fixed to the magnetic particles 215 and the first antibody 211 fixed to the upper surface of the optical waveguide 23. Generates energy that promotes binding. Specifically, the magnetic field generator 32 has an upper magnetic field generator 32a and a lower magnetic field generator 32b, as shown in FIG. Further, the magnetic field generator 32 has a drive circuit (not shown). The magnetic field generator 32 applies a magnetic field to the reaction vessel 201 under the control of the processing circuit 34.

The lower magnetic field generator 32b is composed of, for example, a permanent magnet and an electromagnet. The lower magnetic field generator 32b is provided below the biological reaction device 2. Specifically, the lower magnetic field generator 32b is provided below the mounting table 4 on which the biological reaction device 2 is mounted. For example, the timing at which the application of the lower magnetic field is started and the timing at which the application of the lower magnetic field is stopped are predetermined. The lower magnetic field generator 32b uniformly generates a vertically downward magnetic field, which is energy for promoting the reaction in the reaction vessel 201, in the horizontal direction. Due to the generated vertical downward magnetic field, the magnetic particles 215 to which the second antibody 214 is bound are lowered by receiving the vertical downward force. At this time, the lower magnetic field generator 32b brings the magnetic particles 215 to which the second antibody 214 is bound closer to the optical waveguide 23 by generating a magnetic field of a predetermined strength.

The upper magnetic field generator 32a is composed of, for example, a permanent magnet and an electromagnet. The upper magnetic field generator 32a is provided above the biological reaction device 2 as shown in FIG. For example, the timing at which the application of the upper magnetic field is started and the timing at which the application of the upper magnetic field is stopped are predetermined. For example, the timing for starting the application of the upper magnetic field is set to the time when a predetermined time has elapsed from the timing when the application of the lower magnetic field is stopped. The upper magnetic field generator 32a uniformly generates a vertically upward magnetic field in the reaction vessel 201 in the horizontal direction. Due to the generated vertical upward magnetic field, the magnetic particles 215 to which the second antibody 214 is bound rise by receiving a vertically upward force. At this time, the upper magnetic field generator 32a selectively moves the magnetic particles 215 to which the second antibody 214 is bound away from the sensing area 205 by generating a magnetic field having a predetermined strength. That is, in the upper magnetic field generator 32a, by adjusting the strength of the generated magnetic field, the first antibody 211 fixed on the upper surface of the optical waveguide 23 and the second antibody 214 that binds via the antigen 212 are bound. It is possible to keep only the magnetic particles 215 in the sensing area 205.

The storage circuit 33 has a recording medium that can be read by a processor, such as a magnetic or optical recording medium or a semiconductor memory. The storage circuit 33 stores a program executed in the circuit of the sample test device 10A. A part or all of the program and data in the storage medium of the storage circuit 33 may be configured to be downloaded via an electronic network.

The storage circuit 33 stores information indicating the light intensity of the emitted light L2 supplied from the photodetector 312, time-series data of information indicating the light intensity, inspection results of the test substance to be measured, and the like.

The storage circuit 33 stores a time schedule for measuring the target test substance. The time schedule is, for example, the timing at which the application of the lower magnetic field generated by the lower magnetic field generator 32b is started, the timing at which the application of the lower magnetic field is stopped, the timing at which the application of the upper magnetic field is started, and the measurement are performed. It's timing. These timings are obtained in advance empirically and experimentally.

The processing circuit 34 is, for example, a processor that controls each constituent circuit of the sample testing device 10A. The processing circuit 34 functions as the center of the sample testing device 10A. The processing circuit 34 calls each operation program from the storage circuit 33 and executes the called program to realize the control function 341, the communication function 342, and the measurement function 343. The control function 341 is an example of a "control unit". The communication function 342 is an example of a "communication unit". The measurement function 343 is an example of an “inspection unit”.

The measurement function 343 performs an inspection for detecting a detection target contained in a sample by using a biological reaction device 2, a light source 311, a photodetector 312, and a magnetic field generator 32.

Specifically, the measurement function 343 and the light source 311 are controlled to generate light under predetermined conditions. In the measurement function 343, the processing circuit 34 continuously or intermittently generates the incident light L1 from the light source 311 from the start of the measurement to the end of the measurement.

Further, the measurement function 343 controls the magnetic field generator 32 according to the time schedule stored in the storage circuit 33, and switches the application state of energy for promoting the reaction in the reaction vessel 201 of the biological reaction device 2. Specifically, as described above, the timing for starting the application of the lower magnetic field, the timing for stopping the application of the lower magnetic field, the timing for starting the application of the upper magnetic field, and the timing for stopping the application of the upper magnetic field are predetermined. Therefore, the timing for starting the application of the upper magnetic field is set to the time when a predetermined time has elapsed from the timing when the application of the lower magnetic field is stopped. The measurement function 343 reads a time schedule from the storage circuit 33, controls the magnetic field generator 32 based on the read time schedule, and generates a magnetic field in the magnetic field generator 32.

Further, the measurement function 343 derives a test result regarding the amount (for example, antigen concentration, etc.) or presence / absence of the test substance from the optical signal supplied from the photodetector 312. For example, the timing for deriving the inspection result is predetermined, and is set to a time when a predetermined time has elapsed from the timing when the application of the upper magnetic field is started. The measurement function 343 reads the time schedule from the storage circuit 33, and derives the inspection result from the optical signal supplied from the photodetector 312 based on the read time schedule.

For example, the measurement function 343 determines whether or not the sample solution is likely to be positive or negative when a predetermined time elapses from the timing at which the application of the upper magnetic field is started, and the determination result is the test result. Derived as. Specifically, the measurement function 343 compares the intensity of the optical signal acquired when a predetermined time elapses from the timing of starting the application of the upper magnetic field with, for example, the threshold value stored in the storage circuit 33. By doing so, the judgment is made. Here, when the intensity of the acquired optical signal is equal to or less than the threshold value, the measurement function 343 determines that there is a high possibility of being positive as the measurement result of the test substance, and derives the determination result as the test result. On the other hand, when the intensity of the acquired optical signal is greater than the threshold value, the measurement function 343 determines that there is a high possibility of being negative as the measurement result of the test substance, and derives the determination result as the test result.

The control function 341 outputs the inspection result to the output device 41. For example, the control function 341 controls the display 411 and the printer 412 as the output device 41, and presents information on the inspection to the user. Specifically, the control function 341 presents the inspection result regarding the amount or presence / absence of the test substance to the user by displaying it on the display 411 or printing it with a printer.

Further, the control function 341 controls the sample inspection device 10A and the

sample inspection devices

10B and 10C, which are its own devices. The control of the control function 341 will be described later.

The communication function 342 communicates with the

sample testing devices

10B and 10C.

Next, the

sample testing devices

10B and 10C, which are the slave sample testing devices 10, will be described. FIG. 4 is a block diagram showing an example of the configuration of the

sample testing devices

10B and 10C according to the present embodiment.

As described above, the

sample test devices

10B and 10C are not provided with the input / output device 40 from the viewpoint of cost.

The measurement function 343 uses the biological reaction device 2, the light source 311, the photodetector 312, and the magnetic field generator 32 to perform an inspection for detecting the detection target contained in the sample. The communication function 342 communicates with the sample test device 10A. The control function 341 operates under the control of the sample testing device 10A. The control of the control function 341 will be described later.

The word "processor" used in the above description is, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an integrated circuit for a specific application (Application Specific Integrated Circuit: ASIC)), a programmable logic device (for example, a simple one). It means a circuit such as a programmable logic device (Simple Programmable Logic Device: SPLD), a composite programmable logic device (Complex Programmable Logic Device: CPLD), and a field programmable gate array (Field Programmable Gate Array: FPGA). When the processor is, for example, a CPU, the processor realizes the function by reading and executing the program stored in the storage circuit 60. On the other hand, when the processor is, for example, an ASIC, the program is directly incorporated in the circuit of the processor instead of storing the program in the storage circuit 60. It should be noted that each processor of the present embodiment is not limited to the case where each processor is configured as a single circuit, and a plurality of independent circuits may be combined to form one processor to realize its function. good. Further, the plurality of components in FIGS. 3 and 4 may be integrated into one processor to realize the function.

Here, since the sample test system includes a plurality of sample test devices 10 composed of a master sample test device 10 and a slave sample test device 10, for example, the user can use the master sample test device 10. By operating only one unit, it is possible to operate a plurality of sample testing devices to perform various tests at the same time, and it is possible to improve the testing efficiency. Further, since the slave sample test device 10 is not provided with the input / output device 40 from the viewpoint of cost, it is possible to inexpensively configure a sample test system capable of performing a plurality of tests at the same time. However, since the input / output device 40 is not provided in the slave sample test device 10, the following problems arise in the above sample test system.

For example, since the input / output device 40 is not provided in the slave sample test device 10, there arises a problem that it is not possible to know what test is planned. Specifically, when the virus B is tested by the sample test device 10B, which is the slave sample test device 10, the user uses a sample test device different from the sample test device 10B due to a mistake or the like. There is a possibility that it will end up. For example, the user may attach the biological reaction device 2 for virus B testing to the sample testing device 10C. For example, the user may attach the biological reaction device 2 for virus A testing to the sample testing device 10B. As described above, in the sample test system of the present embodiment, if the type of the biological reaction device 2 mounted on the sample test device 10 is wrong, the test may be redone and the test efficiency may decrease. ..

Further, since the input / output device 40 is not provided in the slave sample inspection device 10, there arises a problem that it is not possible to know what is being inspected. Specifically, when the virus B is tested by the sample test device 10B, which is the slave sample test device 10, the sample test device 10B has the cover 20 closed at the time of the test, so that the virus B test is performed. It is not possible to confirm the color-coded blue color on the biological reaction device 2 for the virus. In this situation, the user confirms what test item is currently being tested by visually recognizing the screen displayed on the display 411 of the sample test device 10A, which is the master sample test device 10. can do. However, if the user cannot approach the sample test device 10A displayed on the screen because he / she is performing another work or the like, he / she can see at a glance what test item is currently being tested. I can't confirm with. When the user approaches the sample testing device 10A for confirmation, the work performed by the user is interrupted, which may reduce the testing efficiency.

Therefore, in the sample testing system of the present embodiment, an indicator 35 is provided in the main body 30 of the sample testing devices 10A to 10C in FIGS. 1, 3 and 4 in order to improve the testing efficiency. The indicator 35 has a light emitting unit capable of emitting different colors. Examples of the color that the indicator 35 can emit light include green and blue. The light emitting portion of the indicator 35 is formed so that the user can easily see it. For example, the light emitting portion of the indicator 35 is formed in a convex shape so as to protrude from the front surface of the main body portion 30.

Then, in the sample test system in this embodiment, the following processing is performed so that the test efficiency can be improved. The sample test device 10 according to the present embodiment includes a measurement function 343, an input / output device 40, a communication function 342, and a control function 341 in the master sample test device 10. The measurement function 343 detects a detection target included in the sample. The input / output device 40 includes a display 411 that displays information related to inspection, and an input device 42 that receives input of information related to inspection. The communication function 342 communicates with the slave sample inspection device 10. Here, the slave sample inspection device 10 has a measurement function 343. The control function 341 causes the communication function 342 to transmit control information used for controlling the slave sample inspection device 10. For example, the master sample test device 10 and the slave sample test device 10 further include an indicator 35, and the control function 341 of the master sample test device 10 carries out the test by transmitting control information from the communication function 342. The indicator 35 of the sample test device 10 selected as the device to perform the test is controlled so as to emit light in a color corresponding to the type of the detection target of the test. Further, the control function 341 processes the detection result received from the slave sample inspection device 10.

5 to 7 are flowcharts showing the procedure of processing by the sample test system 1 in the present embodiment. 8A to 8G are diagrams for explaining the processing by the sample test system 1 in the present embodiment.

In step S100 of FIG. 5, the control function 341 of the sample test device 10A, which is the master sample test device 10, receives a test order from, for example, a HIS (Hospital Information System) server, and is scheduled to be ordered based on the test order. After displaying the list of inspections, the selection of inspection items is accepted as the detection target. For example, as shown in FIG. 8A, the control function 341 displays a screen for accepting the selection of the inspection item on the display 411, and the control function 341 accepts the selection of the inspection item to be performed via the input device 42.

Specifically, the control function 341 recognizes the operating status of the

sample testing devices

10A, 10B, and 10C, and includes an area 110 for accepting selection of test items and an area 120 for displaying the operating status of the sample testing device 10A. The area 130 for displaying the operating state of the sample testing device 10B and the area 130 for displaying the operating state of the sample testing device 10C are overlapped and displayed on the display 411. For example, the

areas

110, 120, 130, and 140 include tabs having different display positions, and the tabs of the

areas

110, 120, 130, and 140 are used to identify the

areas

110, 120, 130, and 140, respectively. "Item", "1", "2", "3" are written.

First, the control function 341 displays the entire area 110 and only the tabs of the

areas

120, 130, and 140 on the display 411. In this case, the

inspection item columns

111, 112, 113 that accept the selection of the inspection item are displayed in the area 110. For example, the

inspection item columns

111, 112, and 113 are displayed for each line, and the inspection item is selected by selecting the displayed line.

In the test item column 111, the test item "virus A", the ID "111111" of the patient as a sample, the name "YYYY", and the usage status "3" are displayed. Here, the usage state "3" in the test item column 111 means that the sample test device 10C is testing the patient with the ID "111111" and the name "YYYY" for "virus A". means. In this case, the sample test device 10C is a sample test device that is performing the test, and the test item column 111 cannot be selected by the user.

In the test item column 112, the test item "virus A", the patient ID "123456" as a sample, the name "XXXX", and the usage status "standby" are displayed. Here, the usage state "standby" in the test item column 112 means that the test for "virus A" has not been performed on the patient with the ID "123456" and the name "XXXX". Further, in the test item column 113, the test item "virus B", the ID "123456" of the patient as a sample, the name "XXXX", and the usage state "standby" are displayed. Here, the usage state "standby" in the test item column 113 means that the test for "virus B" has not been performed on the patient with the ID "123456" and the name "XXXX". In this case, the

sample test devices

10A and 10B are sample test devices that have not been tested, and the test item columns 112 and 113 are in a state that can be selected by the user.

Here, when the inspection item fields 112 and 113 are selected by the user, the control function 341 accepts the selection of the inspection items "virus A" and "virus B" as detection targets. For example, since the patients displayed in the test item fields 112 and 113 are patients with the ID "123456" and the name "XXXX", when the test item field 112 or the test item field 113 is selected by the user, the control function 341 accepts selection of inspection items "virus A" and "virus B" as detection targets.

In step S101 of FIG. 5, the control function 341 of the sample testing device 10A assigns a test item to each sample testing device as a selected detection target.

Specifically, the control function 341 selects a sample testing device that can be tested from the

sample testing devices

10A, 10B, and 10C. For example, the control function 341 selects the

sample testing devices

10A and 10B to which the instruction described later for causing the indicator 35 to emit light is not sent. Then, the control function 341 assigns the test items “virus A” and “virus B” selected in step S100 to the

sample test devices

10A and 10B, respectively.

Alternatively, the control function 341 displays a list of testable sample test devices from the

sample test devices

10A, 10B, and 10C, and then accepts the selection of the testable sample test device via the input device 42. .. For example, the control function 341 accepts selection of testable

sample testing devices

10A and 10B by operating the input device 42. Then, the control function 341 assigns the test items “virus A” and “virus B” selected in step S100 to the

sample test devices

10A and 10B, respectively.

In step S102 of FIG. 5, the test item "virus A" is inspected by the sample inspection device 10A, and the inspection item "virus B" is inspected by the sample inspection device 10B.

First, the inspection of the inspection item "virus A" by the sample inspection apparatus 10A will be described.

In step S110 of FIG. 6, the control function 341 of the sample test device 10A lights the indicator 35 of the sample test device 10A in green color-coded according to the test item “virus A”.

Specifically, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10A so that it lights up in green before the test of the test item "virus A" is performed. For example, as shown in FIG. 8B, the control function 341 of the sample testing device 10A is green and lights the indicator 35 of the sample testing device 10A.

Note that the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10A so as to light up in a color indicating the test item "virus A", but the present invention is not limited to this. For example, when the indicator 35 has a light emitting unit capable of displaying a character string, the control function 341 of the sample test device 10A displays the test item "virus A" as a character string, so that the indicator 35 of the sample test device 10A is displayed. May be controlled.

In step S111 of FIG. 6, the control function 341 of the sample test device 10A displays the guide information for opening the cover 20 on the display 411 as the guide information of the test performed by the sample test device 10A.

Specifically, as shown in FIG. 8C, the tab of the area 120 displayed on the display 411 of the sample testing device 10A is shown in green. Here, it is assumed that the user has selected the tab of the area 120 indicated in green, which is the same color as the color lit on the indicator 35 of the sample testing device 10A. In this case, the control function 341 causes the display 411 to display the entire area 120 and only the tabs of the

areas

110, 130, and 140. In this case,

columns

121, 122, 123, 124 are displayed in the area 120. The inspection item "virus A" is displayed in column 121. In column 122, the ID "123456" and the name "XXXX" of the patient as a sample are displayed. In the column 123, for example, the message "Please open the cover of the device in which the lamp is lit" is displayed as guide information for opening the cover 20 of the sample testing device 10A. In the column 124, the guide information of the column 123 is displayed as an illustration.

In step S112 of FIG. 6, when the detection unit 31 of the sample inspection device 10A detects that the cover 20 has been opened from the main body 30, it outputs information indicating that the cover 20 has been opened.

In step S113 of FIG. 6, the control function 341 of the sample test device 10A uses the biological reaction device 2 as guide information for the test performed by the sample test device 10A according to the information indicating that the cover 20 has been opened. The guide information for mounting is displayed on the display 411.

Specifically, as shown in FIG. 8D, in the area 120 displayed on the display 411 of the sample test device 10A, the column 123 provides guide information for mounting the biological reaction device 2 on the sample test device 10A. , For example, the message "Please install the inspection cartridge." Is displayed. In the column 124, the guide information of the column 123 is displayed as an illustration.

In step S114 of FIG. 6, the reading device 313 of the sample testing device 10A confirms the type of the biological reaction device 2 mounted on the sample testing device 10A.

Specifically, the reading device 313 is a type of the biological reaction device 2 from the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2 when the biological reaction device 2 is attached to the sample testing device 10A. Is read, and reading information indicating the type of the biological reaction device 2 is output. At this time, the control function 341 of the sample inspection device 10A acquires the reading information output from the reading device 313.

In step S115 of FIG. 6, the control function 341 of the sample test device 10A collates the test item “virus A” assigned to the sample test device 10A with the type of the biological reaction device 2 represented by the acquired read information, and the living body. The display 411 displays the collation result indicating whether or not the type of the reaction device 2 is the device used for the inspection item “virus A”.

For example, it is assumed that the type of the biological reaction device 2 represented by the read information is not the biological reaction device 2 for testing the test item "virus A" assigned to the sample test device 10A. That is, when the biological reaction device 2 for virus A test is not correctly attached to the sample test device 10A (step S115; No in FIG. 6), the control function 341 of the sample test device 10A is attached to the sample test device 10A. The user is notified by, for example, a pop-up screen that the type of the biological reaction device 2 is wrong. After that, the process of step S113 is performed again.

For example, it is assumed that the type of the biological reaction device 2 represented by the read information is the biological reaction device 2 for testing the test item "virus A" assigned to the sample test device 10A. That is, when the biological reaction device 2 for virus A test is correctly attached to the sample test device 10A (step S115; Yes in FIG. 6), the process of step S116 is performed.

In step S116 of FIG. 6, the control function 341 of the sample test device 10A displays the guide information prompting the liquid delivery to the biological reaction device 2 on the display 411 as the guide information of the test performed by the sample test device 10A.

Specifically, as shown in FIG. 8E, in the region 120 displayed on the display 411 of the sample testing device 10A, the column 123 contains the sample solution and the reagent from the hole 21a of the biological reaction device 2 to the reaction vessel 201. As guide information prompting to inject the mixed solution 202 of the above, for example, the message "Please send the solution to the inspection cartridge" is displayed. In the column 124, the guide information of the column 123 is displayed as an illustration.

In step S117 of FIG. 6, the control function 341 of the sample testing device 10A displays the guide information prompting the liquid to be sent to the biological reaction device 2 on the display 411, and when a predetermined time has elapsed, the sample testing device 10A As the guide information for the inspection carried out by the above, the guide information for closing the cover 20 is displayed on the display 411.

Specifically, as shown in FIG. 8F, in the area 120 displayed on the display 411 of the sample test apparatus 10A, the column 123 contains, for example, the message “Close the cover” as guide information for closing the cover 20. Please. The inspection will start. ”Is displayed. In the column 124, the guide information of the column 123 is displayed as an illustration.

In step S118 of FIG. 6, when the detection unit 31 of the sample inspection device 10A detects that the cover 20 is closed in the main body 30, it outputs information indicating that the cover 20 is closed.

In step S119 of FIG. 6, the measurement function 343 of the sample test device 10A starts the test performed by the sample test device 10A according to the information indicating that the cover 20 is closed. At the same time, the control function 341 of the sample test device 10A blinks the indicator 35 of the sample test device 10A in green color-coded according to the test item “virus A”.

Specifically, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10A so as to blink in green during the test of the test item "virus A". In this way, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10A so as to emit light in different light emission modes before and during the test.

In step S119 of FIG. 6, the control function 341 of the sample inspection device 10A monitors whether or not the inspection of the measurement function 343 is completed.

If the inspection of the measurement function 343 is not completed (step S119; No in FIG. 6), the process of step S119 is performed again.

On the other hand, when the test of the measurement function 343 is completed (step S119; Yes in FIG. 6), the measurement function 343 of the sample test device 10A stores the test result of the test item “virus A” in the storage circuit 33, and steps S120. Is processed.

In step S120 of FIG. 6, the control function 341 of the sample test device 10A turns off the indicator 35 of the sample test device 10A.

In step S121 of FIG. 6, the control function 341 of the sample test device 10A causes the output device 41 to output the test result of the test item “virus A” carried out by the measurement function 343. For example, the control function 341 controls the display 411 and the printer 412 as the output device 41, and presents the inspection result to the user. Specifically, the control function 341 presents the inspection result to the user by displaying it on the display 411 or printing it with a printer.

Next, the inspection of the inspection item "virus B" by the sample inspection apparatus 10B will be described. The control function 341 of the sample test device 10A causes the communication function 342 to transmit control information used for controlling the sample test device 10B, which is a slave sample test device, and receives the control information from the sample test device 10B as follows. Process the detection result.

In step S130 of FIG. 7, the control function 341 of the sample test device 10A instructs the sample test device 10B to light the indicator 35 in blue color-coded for the test item “virus B”.

Specifically, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10B so that it lights up in blue before the test of the test item "virus B" is performed. In this case, the control function 341 of the sample test device 10A gives a lighting instruction for lighting the indicator 35 in blue corresponding to the test item "virus B" as a control signal via the communication function 342 of the sample test device 10B. Send to. Here, the control signal or the lighting instruction is an example of "control information".

Note that the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10B so as to light up in a color indicating the test item "virus B", but the present invention is not limited to this. For example, when the indicator 35 has a light emitting unit capable of displaying a character string, the control function 341 of the sample test device 10A displays the test item "virus B" as a character string, so that the indicator 35 of the sample test device 10B is displayed. May be controlled.

In step S131 of FIG. 7, the control function 341 of the sample test device 10B sets the indicator 35 of the sample test device 10B in a color representing the test item “virus B” in response to the lighting instruction transmitted from the sample test device 10A. Turn it on.

In step S132 of FIG. 7, the control function 341 of the sample test device 10A displays the guide information for opening the cover 20 on the display 411 as the guide information of the test performed by the sample test device 10B.

Specifically, as shown in FIG. 8G, the tab of the area 130 displayed on the display 411 of the sample testing device 10A is shown in blue. Here, it is assumed that the user has selected the tab of the area 130 indicated in blue, which is the same color as the color lit on the indicator 35 of the sample testing device 10B. In this case, the control function 341 causes the display 411 to display the entire area 130 and only the tabs of the

areas

110, 120, and 140. In this case,

columns

131, 132, 133, 134 are displayed in the area 130. The inspection item "virus B" is displayed in the column 131. In column 132, the ID "123456" and the name "XXXX" of the patient as a sample are displayed. In column 133, for example, the message "Please open the cover of the device in which the lamp is lit" is displayed as guide information for opening the cover 20 of the sample testing device 10B. In column 134, the guide information of column 133 is displayed as an illustration.

Further, in step S132, the communication function 342 of the sample test device 10A transmits a notification indicating that the guide information for opening the cover 20 is displayed on the display 411 to the sample test device 10B.

In step S133 of FIG. 7, when the detection unit 31 of the sample test device 10B detects that the cover 20 has been opened from the main body 30 of the sample test device 10B, the cover 20 of the sample test device 10B is opened. The information indicating that is output. Here, the notification in step S132 is an example of "control information". For example, the communication function 342 of the sample test device 10B transmits information indicating that the cover 20 of the sample test device 10B has been opened to the sample test device 10A as a reply to the notification in step S132.

In step S134 of FIG. 7, the control function 341 of the sample test device 10A serves as guide information for the test performed by the sample test device 10B according to the information indicating that the cover 20 of the sample test device 10B has been opened. Guide information for mounting the biological reaction device 2 on the sample test device 10B is displayed on the display 411.

Specifically, in the area 130 displayed on the display 411 of the sample test device 10A, column 133 contains, for example, the message "test cartridge" as guide information for mounting the biological reaction device 2 on the sample test device 10B. Please install. ”Is displayed. In column 134, the guide information of column 133 is displayed as an illustration.

Further, in step S134, the communication function 342 of the sample test device 10A transmits to the sample test device 10B a notification indicating that the guide information for mounting the biological reaction device 2 on the sample test device 10B is displayed on the display 411. do.

In step S135 of FIG. 7, the reading device 313 of the sample testing device 10B confirms the type of the biological reaction device 2 mounted on the sample testing device 10B.

Specifically, the reading device 313 of the sample testing device 10B is a living body from the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2 when the biological reaction device 2 is attached to the sample testing device 10B. The type of the reaction device 2 is read, and the reading information indicating the type of the biological reaction device 2 is output. Here, the notification in step S134 is an example of "control information". For example, the communication function 342 of the sample testing device 10B transmits the reading information output from the reading device 313 of the sample testing device 10B to the sample testing device 10A as a reply to the notification in step S134. At this time, the control function 341 of the sample testing device 10A acquires the reading information output from the sample testing device 10B.

In step S136 of FIG. 7, the control function 341 of the sample test device 10A collates the test item “virus B” assigned to the sample test device 10B with the type of the biological reaction device 2 represented by the acquired read information, and the living body. The display 411 displays a collation result indicating whether or not the type of the reaction device 2 is the device used for the inspection item “virus B”.

For example, it is assumed that the type of the biological reaction device 2 represented by the read information is not the biological reaction device 2 for testing the test item "virus B" assigned to the sample test device 10B. That is, when the biological reaction device 2 for virus B test is not correctly attached to the sample test device 10B (step S136; No in FIG. 7), the control function 341 of the sample test device 10A is the main body of the sample test device 10B. The user is notified by, for example, a pop-up screen that the type of the biological reaction device 2 attached to the 30 is wrong. After that, the process of step S134 is performed again.

For example, it is assumed that the type of the biological reaction device 2 represented by the read information is the biological reaction device 2 for testing the test item "virus B" assigned to the sample testing device 10B. That is, when the biological reaction device 2 for virus B test is correctly attached to the sample test device 10B (step S136; Yes in FIG. 7), the process of step S137 is performed.

In step S137 of FIG. 7, the control function 341 of the sample test device 10A guides the liquid to be sent to the biological reaction device 2 mounted on the sample test device 10B as guide information for the test performed by the sample test device 10B. The information is displayed on the display 411.

Specifically, in the region 130 displayed on the display 411 of the sample testing device 10A, the mixed solution 202 of the sample solution and the reagent is injected into the reaction vessel 201 through the hole 21a of the biological reaction device 2 in the column 133. For example, the message "Please send the liquid to the inspection cartridge" is displayed as the guide information prompting the user. In column 134, the guide information of column 133 is displayed as an illustration.

Further, in step S137, the communication function 342 of the sample test device 10A sends a notification indicating that the guide information prompting the liquid to be sent to the biological reaction device 2 mounted on the sample test device 10B is displayed on the display 411 for the sample test. It is transmitted to the device 10B.

In step S138 of FIG. 7, a predetermined time has elapsed since the control function 341 of the sample test device 10A displays the guide information prompting the liquid delivery to the biological reaction device 2 mounted on the sample test device 10B on the display 411. At that time, as the guide information for the test performed by the sample test device 10B, the guide information for closing the cover 20 of the sample test device 10B is displayed on the display 411.

Specifically, in the area 130 displayed on the display 411 of the sample testing device 10A, column 133 contains, for example, the message "Please close the cover" as guide information for closing the cover 20 of the sample testing device 10B. The inspection will start. ”Is displayed. In column 134, the guide information of column 133 is displayed as an illustration.

Further, in step S138, the communication function 342 of the sample test device 10A transmits a notification indicating that the guide information for closing the cover 20 of the sample test device 10B is displayed on the display 411 to the sample test device 10B.

In step S139 of FIG. 7, when the detection unit 31 of the sample test device 10B detects that the cover 20 is closed in the main body 30 of the sample test device 10B, the cover 20 of the sample test device 10B is closed. The information indicating that is output. Here, the notifications in steps S137 and S138 are examples of "control information". For example, the communication function 342 of the sample test device 10B transmits information indicating that the cover 20 of the sample test device 10B has been opened to the sample test device 10A as a reply to the notifications in steps S137 and S138.

In step S140 of FIG. 7, the control function 341 of the sample test device 10A blinks the indicator 35 of the sample test device 10B in blue color-coded according to the test item “virus B”.

Specifically, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10B so as to blink in blue during the test of the test item "virus B". In this way, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10B so as to emit light in different light emission modes before and during the test. In this case, the control function 341 of the sample test device 10A gives a blinking instruction for blinking the indicator 35 in blue corresponding to the test item "virus B" as a control signal via the communication function 342 of the sample test device 10B. Send to. Here, the control signal or the blinking instruction is an example of "control information".

In step S141 of FIG. 7, the control function 341 of the sample test device 10B sets the indicator 35 of the sample test device 10B in a color representing the test item “virus B” in response to the blinking instruction transmitted from the sample test device 10A. Make it blink. At the same time, the measurement function 343 of the sample test device 10B starts the test performed by the sample test device 10B in response to the blinking instruction.

In step S142 of FIG. 7, the control function 341 of the sample inspection device 10B monitors whether or not the inspection of the measurement function 343 is completed.

If the inspection of the measurement function 343 is not completed (step S142; No in FIG. 7), the process of step S119 is performed again.

On the other hand, when the inspection of the measurement function 343 is completed (step S142; Yes in FIG. 7), the process of step S143 is performed.

In step S143 of FIG. 7, the communication function 342 of the sample test device 10B transmits information for reporting that the test performed by the sample test device 10B has been completed to the sample test device 10A.

In step S144 of FIG. 7, the control function 341 of the sample test device 10A turns off the indicator 35 of the sample test device 10B in response to the information for reporting that the test performed by the sample test device 10B has been completed. ..

In this case, the control function 341 of the sample test device 10A transmits, as a control signal, a turn-off instruction for turning off the indicator 35 to the sample test device 10B via the communication function 342. Here, the control signal or the extinguishing instruction is an example of "control information".

In step S145 of FIG. 7, the control function 341 of the sample test device 10B turns off the indicator 35 of the sample test device 10B in response to the turn-off instruction transmitted from the sample test device 10A.

In step S146 of FIG. 7, the communication function 342 of the sample test device 10B transmits the test result of the test item “virus B” carried out by the sample test device 10B to the sample test device 10A in response to the turn-off instruction. The measurement function 343 of the sample test device 10A stores the test result of the test item “virus B” in the storage circuit 33.

In step S147 of FIG. 7, the control function 341 of the sample test device 10A causes the output device 41 to output the test result of the test item “virus B” carried out by the sample test device 10B. For example, the control function 341 controls the display 411 and the printer 412 as the output device 41, and presents the inspection result to the user. Specifically, the control function 341 presents the inspection result to the user by displaying it on the display 411 or printing it with a printer.

According to the above description, in the sample inspection device 10 according to the present embodiment, the measurement function 343 detects the detection target included in the sample. The input / output device 40 includes a display 411 that displays information related to inspection, a printer 412 that prints inspection results of inspection, and an input device 42 that receives input of information related to inspection. The communication function 342 communicates with the slave sample inspection device 10. Here, the slave sample test device 10 has the measurement function 343, but the slave sample test device 10 is not provided with the input / output device 40. In this case, the control function 341 causes the communication function 342 to transmit control information used for controlling the slave sample inspection device 10. For example, the master sample test device 10 and the slave sample test device 10 further include an indicator 35, and the control function 341 of the master sample test device 10 carries out the test by transmitting control information from the communication function 342. The indicator 35 of the sample test device 10 selected as the device to perform the test is controlled so as to emit light in a color corresponding to the type of the detection target of the test. Further, the control function 341 processes the detection result received from the slave sample inspection device 10. In the present embodiment, the case where the slave sample inspection device 10 is not provided with the input / output device 40 has been described, but the slave sample inspection device 10 may be provided with the input / output device 40, or , An input / output device different from the input / output device 40 of the master sample test device 10 may be provided. Further, although the case where the input / output device 40 is not provided in the slave sample test device 10, the slave sample test device 10 may be provided with a printer 412 for printing the test results of the test.

Therefore, in the sample test system of the present embodiment, the test efficiency can be improved by controlling the slave sample test device 10 by the master sample test device 10.

For example, when the master sample test device 10 controls the slave sample test device 10, the user can grasp what test is planned. Specifically, when the virus B is tested by the sample test device 10B, which is the slave sample test device 10, the sample test device 10B causes the indicator 35 to emit light in blue corresponding to the test item "virus B". ing. Therefore, the user can attach the biological reaction device 2 for virus B testing to the sample testing device 10B by visually recognizing the blue light emitted from the indicator 35 of the sample testing device 10B. As a result, in the present embodiment, the risk of the user using a sample testing device different from the sample testing device 10B due to a mistake or the like is reduced. As described above, in the sample test system of the present embodiment, the user can correctly attach the biological reaction device 2 to the sample test device 10, so that the test efficiency is improved.

Further, by controlling the sample inspection device 10 of the master by the sample inspection device 10 of the master, the user can grasp what is being inspected. Specifically, when the virus B is tested by the sample test device 10B, which is the slave sample test device 10, the cover 20 of the sample test device 10B is closed at the time of the test, but the sample test device 10B Is blue according to the inspection item "virus B" and causes the indicator 35 to emit light. Therefore, when the user is performing another work, even if he / she does not approach the sample test device 10A displayed on the screen, the sample test device can determine what test item is currently being tested. It can be confirmed at a glance by the light emission of the indicator 35 of 10B. As described above, in the sample test system of the present embodiment, it is possible to confirm what test item is currently being tested without interrupting the work performed by the user, so that the test efficiency is improved. improves.

In the sample test system of the present embodiment, the test efficiency can be improved even with the sample test device 10 alone.

For example, the master sample test device 10 uses the biological reaction device 2 to perform a test for detecting a detection target contained in the sample, a measurement function 343, an indicator 35 capable of emitting different colors, and a control function 341. By providing, the user can grasp what kind of inspection is planned. Specifically, the control function 341 is a color according to the type of the detection target, and is a color-coded color for the biological reaction device 2 and a color-coded color for the reagent package to react with the biological reaction device 2. The indicator 35 is controlled so as to emit light in the same color. For example, when the virus A is inspected by the sample inspection apparatus 10, the control function 341 is green according to the inspection item "virus A" and is color-coded into the biological reaction device 2 for the virus A inspection. The indicator 35 is made to emit light in the same green color as the color and the color-coded color in the package of the reagent to react with the biological reaction device 2 for virus A test. Therefore, the user can attach the biological reaction device 2 for virus A test to the sample test device 10 by visually recognizing the green light emitted from the indicator 35 of the sample test device 10. As described above, in the sample test system of the present embodiment, the user can correctly attach the biological reaction device 2 to the sample test device 10, so that the test efficiency is improved.

(Other embodiments)
Although the embodiments have been described so far, various different embodiments may be implemented in addition to the above-described embodiments.

In the above-described embodiment, the sample testing device 10A, which is the master sample testing device 10, has described, for example, the processing when a test order is received from the HIS server, but the embodiment is not limited to this. Hereinafter, the processing performed without receiving the inspection order will be described. In the process performed without receiving the test order, for example, the biological reaction device 2 is attached to the sample test device 10 that can be tested among the plurality of sample test devices 10 and is selected by the user. .. In this case, the sample test device 10A, which is the master sample test device 10, accepts the test by the selected sample test device 10.

9 and 10 are flowcharts showing the procedure of processing by the sample test system 1 in the modified example of this embodiment.

Here, a case where the user selects the sample test device 10A as the testable sample test device 10 and attaches the biological reaction device 2 for virus A test to the sample test device 10A will be described with reference to FIG.

In the process of FIG. 9, the process procedure is different from the process of FIG. 6, and for example, steps S111, S112, S114, S200, S110, and S116 to S122 are executed. Here, in the process of FIG. 9, step S200 is executed instead of step S115 of FIG.

Specifically, as shown in FIG. 9, first, steps S111, S112, and S114 are executed. For example, in step S114, when the biological reaction device 2 is attached to the sample test device 10A, the reading device 313 transfers the biological reaction device 2 from the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2. The type is read, and the reading information indicating the type of the biological reaction device 2 is output. At this time, the control function 341 of the sample inspection device 10A acquires the reading information output from the reading device 313. After that, the process of step S200 is performed.

In step S200 of FIG. 9, the control function 341 accepts the inspection of the detection target from the type of the biological reaction device 2 represented by the acquired read information. For example, the type of biological reaction device 2 represented by the read information is a biological reaction device 2 for testing virus A. In this case, the control function 341 accepts the inspection of the inspection item "virus A" as the detection target based on the type of the biological reaction device 2 represented by the read information. After that, the process of step S110 is performed.

For example, in step S110, the control function 341 controls the indicator 35 of the sample inspection device 10A so that it lights up in green before the inspection of the inspection item “virus A” is performed. After that, steps S116 to S122 are executed.

Next, a case where the user selects the sample test device 10B as the testable sample test device 10 and attaches the biological reaction device 2 for virus B test to the sample test device 10B will be described with reference to FIG.

In the process shown in FIG. 10, the processing procedure is different from the process shown in FIG. 7, and for example, steps S132 to 135, S210, S130, S131, and S137 to S147 are executed. Here, in the process shown in FIG. 10, step S210 is executed instead of step S136 in FIG. 7.

Specifically, as shown in FIG. 10, first, steps S132 to S135 are executed. For example, in step S135, the reading device 313 of the sample testing device 10B starts with the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2 when the biological reaction device 2 is attached to the sample testing device 10B. The type of the biological reaction device 2 is read, and the reading information indicating the type of the biological reaction device 2 is output. At this time, the communication function 342 of the sample testing device 10B transmits the reading information output from the reading device 313 of the sample testing device 10B to the sample testing device 10A as a reply to the notification in step S134. At this time, the control function 341 of the sample testing device 10A acquires the reading information output from the sample testing device 10B. After that, the process of step S210 is performed.

In step S210 of FIG. 10, the control function 341 accepts the inspection of the detection target from the type of the biological reaction device 2 represented by the acquired read information. For example, the type of biological reaction device 2 represented by the read information is the biological reaction device 2 for virus B inspection. In this case, the control function 341 accepts the inspection of the inspection item "virus B" as the detection target based on the type of the biological reaction device 2 represented by the read information. After that, the processes of steps S130 and S131 are performed.

For example, in step S130, the control function 341 of the sample test device 10A controls the indicator 35 of the sample test device 10B so that it lights up in blue before the test of the test item “virus B” is performed. In this case, the control function 341 of the sample test device 10A gives a lighting instruction for lighting the indicator 35 in blue corresponding to the test item "virus B" as a control signal via the communication function 342 of the sample test device 10B. Send to.

Next, in step S131, the control function 341 of the sample test device 10B sets the indicator 35 of the sample test device 10B in a color representing the test item “virus B” in response to the lighting instruction transmitted from the sample test device 10A. Turn it on. After that, steps S137 to S147 are executed.

According to the above description, in the sample testing device 10 according to the modified example of the present embodiment, in addition to the above-mentioned effects, the case where the biological reaction device 2 is attached to the sample testing device 10 selected by the user is used as a trigger. It is possible to accept the inspection by the selected sample inspection apparatus 10.

Here, the structure of the indicator 35 will be described.

FIG. 11 is a side sectional view showing a first structure which is an example of the structure of the indicator 35 in the sample inspection device 10 according to the present embodiment. As shown in FIG. 11, the indicator 35 includes a substrate 351 and a multi-color LED (Light Emitting Diode) 352 provided on the substrate 351 and a case 353 that covers the multi-color LED 352.

The substrate 351 is provided on the front surface of the main body 30 of the sample inspection device 10. The multicolor LED 352 is a light emitting unit provided on the substrate 351 and capable of emitting a plurality of colors. For example, the multicolor LED 352 emits an arbitrary color by mixing red (R), green (G), and blue (B), which are the three primary colors of light. In the multicolor LED 352, three color LEDs of red (R), green (G), and blue (B) are arranged in close proximity in order to emit an arbitrary color.

In such a multi-color LED 352, the following cases can be considered when emitting a low-brightness color such as brown or gray. First, for example, it may be difficult for the user to distinguish whether or not the LED is emitting light due to the reflected light when the light from the outside is incident on the multicolor LED 352. That is, when the LED does not emit light, it may not appear dark to the user. Next, since the multi-color LED 352 has a structure in which LEDs of three colors are arranged close to each other, the light may not be uniformly mixed.

Therefore, in the example shown in FIG. 11, the case 353 has a light mixing member 353a and a light shielding member 353b.

The light mixing member 353a has a dome shape and mixes a plurality of colors emitted by the multicolor LED 352. As the light mixing member 353a, for example, a white translucent resin is used. The light-shielding member 353b is provided on the light mixing member 353a and blocks light from the outside. As the light-shielding member 353b, for example, a black light-shielding paint is used. Further, at the top of the dome-shaped case 353, an opening 353c is formed which penetrates the light-shielding member 353b and exposes the light mixing member 353a.

For example, a plurality of colors emitted by the multicolor LED 352 are mixed by the light mixing member 353a while being reflected by the dome-shaped inner wall of the light mixing member 353a. In the structure of the light mixing member 353a, the portion (exposed portion) where the opening 353c is formed is thin, so that the light in which the colors are uniformly mixed by the light mixing member 353a is emitted from the opening 353c.

As a result, in the example shown in FIG. 11, the light in which the colors are uniformly mixed by the light mixing member 353a is emitted from the opening 353c. Further, in the example shown in FIG. 11, since the light shielding member 353b blocks the light incident on the multi-color LED 352 from the outside, the user can distinguish whether or not the LED is emitting light. That is, when the LED does not emit light, it looks dark to the user.

Here, in the example shown in FIG. 11, the light in which the colors are uniformly mixed by the light mixing member 353a is emitted from the opening 353c formed at the top of the dome-shaped case 353, so that the emitted light is emitted. The range of is small. Therefore, in order to improve the visibility, it is necessary to enlarge the exit port for emitting the light in which the colors are uniformly mixed by the light mixing member 353a. Therefore, in the example shown in FIG. 12, the exit port is enlarged to improve visibility.

FIG. 12 is a side sectional view showing a second structure which is an example of the structure of the indicator 35 in the sample inspection device 10 according to the present embodiment. As shown in FIG. 12, the indicator 35 includes a substrate 351 and a multi-color LED 352 provided on the substrate 351 and a case 354 that covers the multi-color LED 352. That is, in the example shown in FIG. 12, the indicator 35 includes a case 354 instead of the case 353 in the example shown in FIG. The case 354 has a light mixing member 354a, a light shielding member 354b, and a dimming member 354c.

The light-shielding member 354b is provided on the side surface of the case 354 to block light from the outside. The light-shielding member 354b is, for example, a case in which a black light-shielding paint is used. The light mixing member 354a is provided at a position facing the multicolor LED 352 of the light shielding member 354b, and mixes a plurality of colors emitted by the multicolor LED 352. As the light mixing member 354a, for example, a white translucent film is used. The dimming member 354c is a member that covers the light-shielding member 354b and the light mixing member 354a, and the light in which the colors are uniformly mixed by the light mixing member 354a is emitted from the dimming member 354c. As the dimming member 354c, for example, a dimming film such as an ND (Neutral Density) filter is used. The light-shielding member 354b and the dimming member 354c are provided to improve the visibility of low-brightness colors.

For example, a plurality of colors emitted by the multicolor LED 352 are mixed by being reflected between the light mixing member 354a and the substrate 351. Alternatively, for example, a plurality of colors emitted by the multicolor LED 352 are mixed by being reflected inside the light mixing member 354a. In the example shown in FIG. 12, since the light mixing member 354a is not shielded from light and the dimming member 354c is provided on the light mixing member 354a, the light in which the colors are uniformly mixed by the light mixing member 354a is reduced. It is emitted from the optical member 354c.

As a result, in the example shown in FIG. 12, the light in which the colors are uniformly mixed by the light mixing member 354a is emitted from the dimming member 354c. Further, in the example shown in FIG. 12, since the light shielding member 354b blocks the light incident on the multi-color LED 352 from the outside, the user can distinguish whether or not the LED is emitting light. That is, when the LED does not emit light, it looks dark to the user. Further, in the example shown in FIG. 12, the exit port for emitting the light in which the colors are uniformly mixed by the light mixing member 354a can be made larger than that in the example shown in FIG. 11, so that the visibility is improved. In addition, by providing the dimming member 354c on the light mixing member 354a, the visibility of low-brightness colors can be improved.

Here, the dimming of the indicator 35 will be described.

FIG. 13 is a diagram for explaining an example of dimming of the indicator 35 in the sample inspection device 10 according to the present embodiment. For example, in the sample test device 10A which is the master sample test device 10, when the user requests the dimming of the indicator 35 using the input device 42, the control function 341 of the sample test device 10A accepts the request and receives the request. The screen 360 as shown in FIG. 13 is displayed on the display 411. In FIG. 13, "LED1", "LED2", and "LED3" on the screen 360 are set by the user as colors for lighting the indicator 35. For example, "LED1" and "LED2" are set by the user as color-coded colors for the inspection items "virus A" and "virus B", respectively.

In the screen 360 shown in FIG. 13, the brightness of the red (R), green (G), and blue (B) LEDs (light sources), which are the three primary colors of light, is displayed in the multicolor LEDs 352 of the

sample inspection devices

10A, 10B, and 10C. Each has an adjusting unit 361 to 363 for adjusting and a setting button 364. Each of the adjusting units 361 to 363 includes a button for the user to adjust the color value using the input device 42, and the larger the set color value, the brighter the light source of the color. In FIG. 13, “0” is displayed as the initial value of the color value. For example, when the user operates the setting button 364 by setting the red (R), green (G), and blue (B) values to the maximum values by operating the adjustment units 361 to 363, the indicator 35 The light emitted from is white.

Further, the user sets the value of red (R) to the maximum value, sets the values of green (G) and blue (B) to the minimum value by operating the adjustment units 361 to 363, and presses the setting button 364. When operated, the light emitted from the indicator 35 turns red. Similarly, the user sets the green (G) value to the maximum value and the red (R) and blue (B) values to the minimum value by operating the adjustment units 361 to 363, and sets the setting button 364. When is operated, the light emitted from the indicator 35 turns green. Similarly, the user sets the blue (B) value to the maximum value and the red (R) and green (G) values to the minimum value by operating the adjustment units 361 to 363, and sets the setting button 364. When is operated, the light emitted from the indicator 35 becomes blue.

In this way, the user sets the values of red (R), green (G), and blue (B) to arbitrary values by operating the adjustment units 361 to 363, and operates the setting button 364. The control function 341 of the sample test device 10A can emit a low-brightness color such as brown or gray as the light emitted from the indicator 35.

Here, the dimming of the indicator 35 is performed, for example, at the time of shipment immediately before the sample test device 10 is shipped, or at the time of installation when the sample test device 10 is installed in a hospital or the like. For example, when the user sets blue as the color-coded color for the inspection item "virus B", the user sets the value of blue (B) to the maximum value by operating the adjustment units 361 to 363, and red (R), Set the green (G) value to the minimum value and operate the setting button 364. At this time, the control function 341 of the sample inspection device 10A identifies the information representing the color set on the screen 360 by the user, the information representing the inspection item, and the type of the biological reaction device 2 used for the inspection of the inspection item. The information representing the QR code (registered trademark) 2a to be used is associated with the information and stored in the storage circuit 33 of the sample testing device 10A.

For example, in the present embodiment, the control function 341 of the sample inspection device 10A receives the inspection item "virus A" or "virus B" when the inspection item "virus A" or "virus B" is selected by the user when the inspection order is received from the HIS server. The indicators 35 of the

sample testing devices

10A and 10B, which are testable sample testing devices, are lit in green and blue, respectively, as the colors coded into "virus A" and "virus B" on the screen 360. ..

Further, in the modified example of the present embodiment, the control function 341 of the sample test device 10A obtains the type of the bioreaction device 2 from the QR code (registered trademark) 2a of the bioreaction device 2 attached to the sample test device 10A. When the reading device 313 receives the inspection of the inspection item "virus A" from the type of the read biological reaction device 2, the user displays the inspection item "virus A" on the screen 360 as a color-coded color. The indicator 35 of the sample testing device 10A, which is a testable sample testing device, is turned on in the set green color.

In this way, when the test item is received from the test order or the QR code (registered trademark) 2a, the control function 341 of the sample test device 10A is set by the user on the screen 360 as a color-coded color for the received test item. The indicator 35 can be turned on with the specified color.

According to at least one embodiment described above, the inspection efficiency can be improved.
