[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, when numbers, quantities, etc. are mentioned, the scope of the present disclosure is not necessarily limited to those numbers, quantities, etc., unless otherwise specified. The same reference numerals are used for the same or equivalent parts, and redundant descriptions may not be repeated. It is intended from the beginning that the configurations in the embodiments may be used in appropriate combinations.

[0010] 1 is a diagram showing a schematic configuration of a test device according to the present embodiment, which is used, for example, for drug susceptibility testing.

[0011] The test device 100 captures an image of each of a plurality of observation points provided on the culture plate 110. At each of the plurality of observation points, an observation target obtained by bringing a test liquid containing bacteria, which is a biological agent, into contact with an agent is placed.

[0012] The testing apparatus 100 includes a testing section 100A that performs testing and a disposal section 100B that collects waste discharged from the testing section 100A. The testing section 100A includes a control device 120, a microscope camera 140, a stage 160, a reading section 180, and an incubator 20. The disposal section 100B includes a disposal device 1, an optical sensor 151, a Hall sensor 152, and a locking mechanism 153. The control device 120 is electrically connected to the microscope camera 140, the stage 160, the reading section 180, the optical sensor 151, the Hall sensor 152, and the locking mechanism 153. Note that some or all of the electrically connected devices may be configured as an integrated unit.

[0013] The control device 120 controls each of the microscope camera 140 and the stage 160 based on the information read by the reading unit 180 in order to capture an image of each observation point on the culture plate 110 .

[0014] The microscope camera 140 includes an objective lens 142 , a focus change mechanism 144 , and an image sensor 146 .

[0015] The objective lens 142 magnifies a part of the culture plate 110 placed on the stage 160. The objective lens 142 is arbitrarily selected depending on the object to be observed.

[0016] The focus change mechanism 144 changes the focus of the microscope camera 140. As an example, the focus change mechanism 144 changes the position of the objective lens 142 in the optical axis direction of the objective lens 142, thereby changing the focus of the microscope camera 140.

[0017] The image sensor 146 is a detector for capturing an image of the object of observation magnified by the objective lens 142, and is, for example, a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor.

[0018] The stage 160 includes an imaging field of view changing mechanism 162 and an illumination device 164. The culture plate 110 is placed on the stage 160. The illumination device 164 is a transmitted illumination device that irradiates the stage 160 with light for observation.

[0019] The imaging field of view changing mechanism 162 changes the imaging field of view of the microscope camera 140. The imaging field of view changing mechanism 162 includes an X-axis movement mechanism 162X and a Y-axis movement mechanism 162Y. The X-axis movement mechanism 162X moves the culture plate 110 placed on the stage 160 in the X-axis direction in Figure 1. The Y-axis movement mechanism 162Y moves the culture plate 110 placed on the stage 160 in the Y-axis direction in Figure 1.

[0020] The reading unit 180 reads the identification information of the culture plate 110. The reading unit 180 is, for example, a barcode reader, a QR code (registered trademark) reader, or a reader compatible with RF (Radio Frequency) tags, and is selected depending on the type of identification code attached to the culture plate 110. The reading unit 180 transmits the read identification information to the control device 120.

[0021] Based on the identification information from the reading unit 180, the control device 120 reads out the imaging conditions corresponding to the identification information, and controls the microscope camera 140 and the stage 160 based on the read-out imaging conditions to capture images of each observation point.

[0022] Specifically, the control device 120 outputs observation point information indicating the position of the observation point to be imaged to the imaging field of view changing mechanism 162. The imaging field of view changing mechanism 162 moves the culture plate 110 in accordance with the output observation point information, and positions the observation point to be imaged within the imaging field of view of the microscope camera 140.

[0023] The control device 120 issues a focus change instruction to the focus change mechanism 144 in accordance with the imaging conditions. At this time, the control device 120 outputs a focus position at which the microscope camera 140 is focused on the observation point of the imaging target to the focus change mechanism 144. The focus change mechanism 144 sets the focus of the microscope camera 140 to the output focus position.

[0024] When the imaging field of view and focus of the microscope camera 140 are set, the control device 120 issues an imaging instruction to the image sensor 146 and obtains image data. The control device 120 obtains the number of bacteria, the shape of the bacteria, and the like as observation results from the image data.

[0025] The incubator 20 sets the culture plate 110 into which the test liquid has been pressed to a temperature suitable for culturing bacteria (for example, 37 degrees).

[0026] The disposal device 1 collects culture plates 110, which are waste materials that have been observed and are no longer needed. An optical sensor 151 is disposed above the disposal device 1. The optical sensor 151 is a sensor that detects whether or not a culture plate 110 is present in the disposal device 1 by means of reflected light. A signal from the optical sensor 151 is sent to the control device 120.

[0027] A Hall sensor 152 is disposed below the disposal device 1. The Hall sensor 152 is a sensor for detecting a magnetic force from a magnet attached to the disposal device 1. A signal from the Hall sensor 152 is sent to the control device 120.

[0028] The disposal unit 100B includes a locking mechanism 153 for fixing the disposal device 1 to the testing device 100. The locking mechanism 153 prevents the disposal unit 100B (disposal device 1) from coming off the testing device 100 during testing when the disposal device 1 is in a lower position. The locking mechanism 153 has a motor (not shown) and a shaft (not shown) that moves up and down when driven by the motor.

[0029] 2 is a plan view of the culture plate 110. The culture plate 110 includes a plate-like member 112 and a flow channel structure.

[0030] The plate-shaped member 112 is made of an acrylic resin such as polymethyl methacrylate resin. The thickness of the plate-shaped member 112 is not particularly limited, but is set to, for example, 1 mm to 6 mm. An identification code 118 for individually identifying the culture plate 110 is attached to the plate-shaped member 112.

[0031] An overview of the test will be described with reference to Figure 1. In this embodiment, the test device 100 is used to observe the state of bacteria after contacting the bacteria with a drug. The culture plate 110 into which the test liquid has been injected is stored in an incubator 20 and is removed from the incubator 20 when it is time to observe.

[0032] In the inspection of this embodiment, the culture plate 110 is removed from the incubator 20, images of each of the multiple observation points on the culture plate 110 are taken using the test device 100, and the culture plate 110 is then returned to the incubator 20, and this process is repeated.

[0033] After observation is completed, the culture plate 110, which is no longer needed as waste, is moved from the incubator 20 to the disposal section 100B. The movement of the culture plate 110 between the incubator 20 and the imaging position, and the movement of the culture plate 110 between the incubator 20 and the disposal section 100B are performed by a moving device (not shown). The moving device moves the culture plate 110 based on a signal from the control device 120.

[0034] 3 is a schematic diagram showing an example of the hardware configuration of the control device 120. As an example, the control device 120 is configured according to a general-purpose computer architecture.

[0035] The control device 120 has, as its main components, a processor 122, a memory 124, and an input / output interface (I / F) 126. These components are connected to each other via a bus 128 so that they can communicate with each other.

[0036] The processor 122 is typically an arithmetic processing unit such as a CPU (Central Processing Unit) or an MPU (Multi Processing Unit). The processor 122 controls the operation of each unit of the test apparatus 100 by reading and executing programs stored in the memory 124. Specifically, the processor 122 realizes each process of the test apparatus 100 by executing the programs. Note that although the example of FIG. 3 illustrates a configuration with a single processor, the control apparatus 120 may also be configured with multiple processors.

[0037] The memory 124 is realized by a storage device such as a random access memory (RAM), a read only memory (ROM), a nonvolatile memory such as a flash memory, or a magnetic disk. The memory 124 stores programs executed by the processor 122, data used by the processor 122, etc. Specifically, the memory 124 stores imaging conditions for imaging each observation point on each culture plate 110.

[0038] The input / output I / F 126 is an interface for exchanging various data with the focus changing mechanism 144 , the image sensor 146 , the imaging field of view changing mechanism 162 , the reading unit 180 , the optical sensor 151 , the hall sensor 152 , and the locking mechanism 153 .

[0039] 4 and 5 are diagrams illustrating the disposal device 1 included in the disposal unit 100B according to this embodiment. The disposal unit 100B (disposal device 1) includes a container 3, a bottom member 5, a first gripping unit 2, a second gripping unit 6, and a guide member 8.

[0040] The container 3 contains the culture plate 110, which is waste, and has an inner surface formed of a material that does not react with drugs. The container 3 is made of a metal such as stainless steel. The container 3 may also be made of a resin or the like that is resistant to drugs. The bottom member 5 forms the bottom of the container 3. The bottom member 5 is made of the same material as the container 3. The materials of the container 3 and the bottom member 5 may be any material that is resistant to drugs used in the testing device 100. The materials of the container 3 and the bottom member 5 may be different.

[0041] The disposal device 1 includes a detachment mechanism that ejects the culture plate 110 contained in the container 3 by attaching and detaching the bottom member 5 from the container 3. The detachment mechanism is a mechanism that discards waste by pulling out the bottom member 5 from the container 3 body.

[0042] The first grip part 2 is a handle that the user grips to remove the disposal device 1 from the storage part 101 of the testing device 100. The second grip part 6 is a handle that the user uses to pull out the bottom member 5 from the container 3.

[0043] The container 3 includes guide members 8. The guide members 8 are arranged on both inner sides of a lower position of the container 3, extending along the direction in which the bottom member 5 is pulled out. The guide members 8 slide between the container 3 and the storage section 101 of the testing device 100. The guide members 8 are formed of a resin with high slidability. The container 3 and the guide members 8 are fixed together with screws. The material of the guide members 8 may be other than resin, and the container 3 and the guide members 8 may be fixed together with a method other than screws.

[0044] The container 3 has a first sliding surface 8a on the guide member 8, which allows the container 3 to slide relative to the testing device 100 when the container 3 is removed from the testing device 100. The container 3 has a second sliding surface 8b on the guide member 8, which allows the bottom member 5 to slide relative to the container 3 when the bottom member 5 is pulled out from the container 3.

[0045] The user can easily remove the container 3 from the testing device 100 by sliding the container 3 away from the testing device 100 using the first sliding surface 8a. The user can easily pull out the bottom member 5 from the container 3 by sliding the bottom member 5 relative to the container 3 using the second sliding surface 8b. The guide member 8 is configured to have both the first sliding surface 8a and the second sliding surface 8b in one member, which allows for a reduction in the number of parts.

[0046] The first gripping unit 2 and the second gripping unit 6 are arranged on opposite sides of the container 3. The direction of movement of the second gripping unit 6 when the bottom member 5 is pulled out from the container 3 is opposite to the direction of movement of the first gripping unit 2 when the container 3 is removed from the testing device 100. This makes it easier to pull out the bottom member 5 from the container 3 body than if the first gripping unit 2 and the second gripping unit 6 were arranged in the same direction.

[0047] A magnet 7 is provided below the bottom member 5. The magnet 7 secures the testing device 100 body and the bottom member 5 together with magnetic force. By providing a magnet on the testing device 100 body in a position facing the magnet 7 when the disposal device 1 is stored in the testing device 100, the disposal device 1 can be secured in an appropriate storage position by magnetic force. The disposal unit 100B is provided with a Hall sensor 152 shown in FIG. 1. The Hall sensor 152 is provided in a position facing the magnet 7 when the disposal device 1 is stored, so it can detect that the bottom member 5 is stored attached to the container 3.

[0048] The disposal device 1 is equipped with a locking portion 154 for preventing the bottom member 5 from being detached from the container 3 during testing. The locking portion 154 is disposed in a position facing the locking mechanism 153 of the disposal unit 100B. The locking portion 154 is a member that extends from the main body of the container 3 toward the bottom member 5 and has a hole formed at its tip. The control device 120 controls the locking mechanism 153, for example, to drive the motor of the locking mechanism 153 during testing, fitting the shaft portion into the hole and fixing the container 3 in the storage position of the testing device 100. After the test is completed or when the power supply is stopped, the shaft portion disengages from the hole, allowing the disposal device 1 to move relative to the testing device 100.

[0049] The testing device 100 is provided with the locking mechanism 153 and the locking portion 154, thereby making it possible to prevent the bottom member 5 from accidentally coming off the container 3 during testing.

[0050] An opening 4 is formed in a part of the side of the container 3, through which the culture plate 110 moved by the moving device passes. An opening 103 is formed along the opening 4 on the opening 4 side of the storage section 101. A guide section 3a that follows the shape of the culture plate 110 is provided inside the container 3. After passing through the opening 4, the culture plates 110 are stacked one after another along the guide section 3a above the bottom member 5. The maximum number of stacked plates is, for example, 48, and the number of stacked plates may be detected by an optical sensor 151.

[0051] 4, guide portions 102 extending diagonally forward from the storage portion 101 are provided on both ends of the first grip portion 2. The guide portions 102 serve as guides when attaching the disposal device 1 to the storage portion 101.

[0052] Next, the flow when removing the disposal device 1 including the containers 3 from the testing device 100 will be described. Figure 6 is a diagram for explaining the procedure for removing the disposal device 1 from the testing device 100. Figure 6(A) shows a state in which the disposal device 1 is stored in the storage section 101 of the testing device 100. From the state shown in Figure 6(A), as shown in Figure 6(B), the user grasps the first gripping section 2 and pulls out the disposal device 1 including the containers 3 toward the user. As a result, the disposal device 1 including the containers 3 is pulled out from the testing device 100 as shown in Figure 6(C).

[0053] As shown in FIG. 6 , when removing the disposal device 1 from the testing device 100 , the user can easily remove the disposal device 1 by gripping the first grip portion 2 .

[0054] 7A and 7B are diagrams illustrating the state of the second gripping part 6 when stored and deployed. As shown in FIG. 6A, a recess 9 for storing the second gripping part 6 is formed at a low position on the back surface of the container 3. The second gripping part 6 is structured so that it can move around the rotating part 6a from the stored state shown in FIG. 6A to the deployed state shown in FIG. 6B. The culture plates 110, which are waste, are solid materials stacked inside the container 3. Multiple culture plates 110 are arranged in a stacked state inside the container 3.

[0055] After removing the disposal device 1 from the testing device 100, the user can grasp the first gripping part 2 provided on the front and the second gripping part 6 stored on the back of the container 3. This allows the user to easily move the disposal device 1 with both hands when it has become heavy due to multiple culture plates 110 being stacked on top of each other.

[0056] 8A and 8B are diagrams illustrating the procedure for pulling out the bottom member 5 from the main body of the container 3. As shown in Fig. 8A, the user holds the first grip portion 2 with one hand (for example, the right hand) and pulls out the second grip portion 6 forward with the other hand (for example, the left hand). As a result, the bottom member 5 is pulled out from the main body of the container 3 as shown in Fig. 8B.

[0057] The user further pulls the bottom member 5 toward the user from the state shown in Fig. 8(B) to completely separate the container 3 from the bottom member 5 as shown in Fig. 8(C) . As the bottom member 5 is pulled out from the container 3 body as shown in Fig. 8(C) , the culture plate 110 falls from the bottom of the container 3 into a waste box 50 disposed below.

[0058] 8 , the testing device 100 can discharge the culture plate 110, which is waste stored in the container 3, by using an attachment / detachment mechanism that attaches and detaches the bottom member 5 from the container 3. This allows the user to safely and easily discharge the waste at a low position in the container 3.

[0059] As shown in Fig. 7, a large number of culture plates 110, which are waste, may be stacked and placed inside the container 3. Stacking increases the weight of the container 3 itself. In the testing device 100, as shown in Fig. 8, the waste can be disposed of by pulling out the bottom member 5 from the container 3 body, so that the waste can be easily disposed of from the bottom side without tilting the heavy container 3.

[0060] As shown in Figures 7 and 8, the first gripping unit 2 and the second gripping unit 6 are arranged on opposite sides of the container 3. In other words, the movement direction of the second gripping unit 6 when the bottom member 5 is pulled out of the container 3 is opposite the movement direction of the first gripping unit 2 when the container 3 is removed from the testing apparatus 100. This makes it easier to pull out the bottom member 5 from the container 3 body than if the first gripping unit 2 and the second gripping unit 6 were arranged in the same direction. For example, if the second gripping unit 6 were located below the first gripping unit 2, it could be accidentally pulled out while the testing apparatus 100 is operating. However, because the first gripping unit 2 and the second gripping unit 6 are arranged on opposite sides of the container 3, it is possible to prevent the bottom member 5 from being pulled out during operation.

[0061] 9A and 9B are diagrams illustrating the state when the second gripping part 6 comes into contact with the testing device 100. As shown in Fig. 9A, the user pushes the disposal device 1 toward the tilting member 104 of the testing device 100. The tilting member 104 is tilted obliquely with respect to the direction in which the disposal device 1 is pushed (the direction of the arrow in Fig. 9).

[0062] 9(B), the second gripping part 6 rotates around the rotating part 6a along the tilting member 104 toward the disposal device 1. As a result, even if a user pushes the second gripping part 6 in the deployed state into the testing device 100, the tilting member 104 can change the second gripping part 6 to the stored state. Note that the testing device 100 may have a structure that does not include the tilting member 104 and is perpendicular to the direction in which the disposal device 1 is pushed in.
