[Embodiment 1]
An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 14. FIG.

(Scope of application of collection system 100)
First, the scope of application of the collection system 100 according to one aspect of the present invention will be described. The collection system 100 is, for example, a system capable of facilitating monitoring of a sample collection operation by a collection device 1 that collects a sample from a subject and management of the collected sample.

Here, "subject" is intended to mean a place, facility, or the like from which a sample of liquid or gas for analysis is taken. For example, the following places, facilities, etc. can be "objects".

・Sewage treatment plants, sewage storage facilities, and water pipes under manholes (samples collected: sewage, gas, etc.)
・Rivers, ponds, lakes, and various waterways (examples of samples taken: water, ambient air)
・Coasts, harbors (example of sample collected: seawater)
・Facilities such as factories that manufacture various products (Examples of collected samples: intermediate products, waste liquids, discharged gases, etc.)
・Space inside a facility or house (example of sample taken: air)
・Various storage tanks, reaction vessels, mixing vessels, and culture vessels (samples collected: reaction solution, culture solution, internal gas, etc.)
For example, feces of an infected person infected with pathogenic viruses and bacteria may contain the viruses and bacteria. For example, by collecting samples (that is, sewage) from sewage treatment plants in each region and extracting and analyzing the genes contained in the samples, it is possible to identify regions with a large number of infected people. Also, by analyzing samples collected periodically, it will be possible to monitor changes in the number of infected people in each region.

In addition, for example, by collecting a sample (that is, exhaust gas) from the exhaust port of a facility such as a factory and analyzing the components contained in the sample, it is possible to evaluate and monitor the effects of the exhaust gas on the environment and organisms (such as health conditions). It is possible.

A sampling system 100 including a sampling device 1 for sampling a sample (for example, sewage) from a sewage treatment facility (target) will be described below as an example.

(Configuration of collection system 100)
First, the configuration of the collection system 100 will be described using FIG. FIG. 1 is a configuration diagram showing a schematic configuration of a collection system 100 according to Embodiment 1 of the present invention.

The collection system 100 includes a collection device 1 that is installed on a target and collects a sample from the target, and a management system 9 . The management system 9 may be, but is not limited to, a cloud system. The management system 9 outputs a collection instruction to the collection device 1, acquires collection completion information from the collection device 1, monitors the sample collection operation of the collection device 1, and manages the collected samples. .

Collection system 100 may include a remote terminal 5 . Remote terminal 5 is a computer used by an administrator who uses collection system 100 . An administrator can access the collection system 100 using a remote terminal 5 from the subject on which the collection device 1 is installed and from a remote location far away from the subject on which the collection device 1 is installed. The remote terminal 5 may be, for example, a personal computer, a tablet terminal, a smart phone, or the like. The remote terminal 5 has a communication function, and can register collection instructions in the management system 9 and view collection completion information. The remote terminal 5 may have, for example, a keyboard, a touch panel, an input unit such as a microphone, and a display unit such as a monitor.

In the collection system 100, the collection device 1 and the management system 9, and the remote terminal 5 and the management system 9 are communicably connected to each other. The remote terminal 5 can also be communicatively connected to the collection device 1 via the management system 9 . For example, as shown in FIG. 1, the management system 9 can connect a plurality of sampling devices 1 (sampling devices 1a, 1b, 1c, . . . ) and a plurality of remote terminals 5 (remote terminals 5a, 5b, . . ) may be communicably connected. The management system 9 and the sampling device 1, and the management system 9 and the remote terminal 5 may be connected by wireless communication, or may be connected by wired communication.

In the sampling system 100, as shown in FIG. 1, sampling devices 1a, 1b, 1c, . It may be a configuration. However, the collection system 100 is not limited to such a configuration. For example, in the sampling system 100, the management system 9 can simultaneously manage the sampling device 1a for sampling liquid and the sampling device 1b for sampling gas. In this case, for example, the management system 9 includes (i) a collection device 1a installed in a sewage treatment facility and collecting sewage from the sewage treatment facility, and (ii) a space inside the facility or house. It is only required that the space is communicably connected to the sampling device 1b that samples the air in the space.

(Appearance of sampling device 1)
Next, the appearance of the sampling device 1 will be described with reference to FIG. FIG. 2 is a perspective view showing an example of the overall configuration of the collection device 1. As shown in FIG. FIG. 2 shows the collecting device 1 viewed from above the front.

The sampling device 1 includes a housing C, a door portion D, a container holding portion 32, a pump 31, and a movement path P. Note that the sampling device 1 incorporates a control unit 10 that controls to execute processing of each function (see FIG. 3). The controller 10 will be described later (see FIG. 5).

The housing C is provided with a control unit 10 that controls the sampling operation and data communication by the sampling device 1, and various components (for example, the pump 31, etc.) that are driven along with the sampling operation. The housing C protects the control unit 10 and various components of the sampling device 1 in the target on which the sampling device 1 is installed. It should be noted that there is a case where there is no suitable place for placing the sampling device 1 in the object. For example, the collection device 1 for collecting sewage from a water pipe under a manhole can be installed above the sewage flowing through the water pipe (that is, behind the manhole cover) by being suspended by a string or chain. In this case, a handle portion may be provided in the center of the upper surface of the housing C, through which a string or chain can be passed or a hook can be hung.

The door portion D is attached to the housing C so as to be openable and closable. The door portion D is opened when the container T or the container holder H containing the sample is installed in the sampling device 1 and when the container T and the container holder H containing the sample are removed from the sampling device 1 . 2 to 4 show the collecting device 1 with the door D opened.

When the door portion D is closed, the container T and the container holder H are held in the space surrounded by the housing C and the door portion D. Therefore, the sample contained in the container T may be unintentionally mixed with foreign matter. can be suppressed. Also, the container T containing the sample can be held without being exposed to the weather. Therefore, it can also be expected that the amount of evaporation of the sample from the container T is reduced.

Samples taken from subjects may contain components that are altered or decomposed by light. The housing C and the door portion D of the sampling device 1 for sampling a sample containing such an unstable component may have a light shielding property. As a result, the sample contained in the container T can be held in the light shielding portion that shields light from the outside. Here, the light-shielding portion is a space surrounded by the housing C having a light-shielding property and the door portion D having a light-shielding property.

The container holding part 32 may include a container holder H and a holder base B. As shown in FIG. The container holder H can hold one or more containers T. As shown in FIG. FIG. 2 shows a case where a container holder H holding six containers T is applied. Container information T1 (identification information), which is identification information unique to each container, is assigned to the container T. As shown in FIG. The container information T1 may be attached to or displayed on each container T. FIG. The container information T1 may be, for example, a QR code (registered trademark), a barcode, a character string readable by a known optical character recognition (OCR) function, or the like. Alternatively, the container information T1 may be RFID or the like. In the following, a case where container information T1 is attached in advance to each container T will be described as an example. For example, when an empty container T attached with container information T1 is set in the container holder H, the container information T1 can be set to face in a certain direction. FIG. 2 shows that the container information T1 of the container T set in the container holder H is directed outward in the radial direction of the container holder. The container information T1 assigned in advance to each container T will be described later (see FIG. 11).

The container holder H is placed on the holder base B. As shown in FIG. When the container holder H can hold a plurality of containers T, the container holding part 32 is moved to the accommodation position so that the sample is accommodated in the second container after the sample is accommodated in the first container at the accommodation position. may move the second container to . Here, the accommodation position is intended to be a position where the sample can be accommodated in the container T. FIG. In the example shown in FIG. 2, the accommodation position is a position where a sample coming out from a second end P2 of a movement path P, which will be described later, can be accommodated.

When the position of the second end P2 of the movement path P is fixed, the container holder 32 may be configured to change the position of each container T as the container holder H moves. In the example shown in FIG. 2, the position of the second end P2 of the travel path P is fixed and the vessel holder H may be rotatable clockwise or counterclockwise. A known drive mechanism (for example, a motor, etc.) can be applied to rotate the container holder H. As shown in FIG. The container holding section 32 may have this drive mechanism. For example, when the container holder H holds the containers T in a row, the container holder H may be configured to slide.

On the other hand, when the container holder H is not movable and the position of each container T is fixed, the container holding part 32 moves the second end P2 of the movement path P to the position corresponding to each container T. It may be configured to be moved. In this case, a plurality of second ends P2 may exist. For example, the configuration may be such that samples are accommodated in separate containers T from each of the plurality of second ends P2. When samples are stored in two containers T at the same time, the sample in one container T can be used as an analysis sample, and the sample in the other container T can be used as a preliminary (or re-analysis) sample.

Note that, as shown in FIG. 2, a configuration in which the container holder H is rotated clockwise or counterclockwise is more compact than a configuration in which the second end P2 is moved to a position corresponding to each container T. The device 1 is easy to implement. This is because, in the former case, a space for moving the second end P2 to a position corresponding to each container T must be secured within the light shielding portion of the collection device 1 .

The pump 31 can put the sample into the movement path P from the object, and can move the sample out of the movement path P from inside the movement path P. As the movement path P, a flexible tube made of silicone or the like can be applied. In this case, a peristaltic pump (registered trademark) may be adopted as the pump 31 . A collection device 1 employing a peristaltic pump is capable of collecting liquid and gas samples. The sampling device 1 employing a peristaltic pump is also capable of returning a sample that has entered the movement path P from a subject to the subject. This operation is used when co-washing the inside of the moving path P. The co-washing operation of the sampling device 1 will be described later.

The path of travel P has a first end P1 on the subject side from which the sample is taken and a second end P2 on the container T side from which the taken sample exits. The movement path P is arranged so that the sample can smoothly move from the first end P1 to the second end. For example, if a large amount of previously taken samples remain in the travel path P, new and old samples will be mixed. It is desirable to arrange the movement path P in the housing C so as to avoid such a situation. The manner in which the movement paths P are arranged in the housing C will be described later (see FIG. 13).

Since it is necessary to install the sampling device 1 on each of a plurality of objects, it is desirable that the manufacturing cost of the installation device 1 is low. Therefore, the housing C, the door portion D, the container holder H, the holder base B, etc. of the collection device 1 may be manufactured using a 3D printer. As a result, the manufacturing cost can be reduced while downsizing the collecting device 1 .

Depending on the object, it is not always possible to secure a sufficient space for installing the sampling device 1, so it is desirable that the sampling device 1 be as lightweight and compact as possible. Therefore, the sampling device 1 may be configured to have only the essential functions by omitting the functions that are not essential for sampling from the object. For example, the housing C and the door part D may have the minimum required strength and waterproof function. Thereby, weight reduction of the sampling device 1 can be achieved.

In recent years, the application of highly sensitive analytical techniques has reduced the amount of sample required for analysis. It suffices if a necessary amount of sample can be collected from a subject for analysis, and it is useless to collect more than the necessary amount of sample. Therefore, the sampling device 1 may be configured to accommodate a sample in a container T capable of accommodating an amount of sample to be analyzed. In this case, since the amount of the sample to be collected is small, the size of the container T containing the collected sample is also small. As a result, weight reduction and compactness of the sampling device 1 can be achieved. A specific example of the container T will be described later (see FIG. 11).

Next, the configuration of the rear portion of the container holder H will be described with reference to FIG. 3 is a perspective view showing an example of the configuration of the rear portion of the container holder H. FIG. FIG. 3 is a front top view of the sampling device 1 of FIG. 2 when the container holder H is removed.

As shown in FIG. 3, the housing C is provided with a camera 331 capable of imaging the container T set in the container holder H. As shown in FIG. The camera 331 can capture an image of the container T immediately before, during, and/or after collection. Camera 331 is, for example, a still camera. Camera 331 may be, for example, a digital camera.

The captured image of the container T may include the container information T1 indicated on the container T. FIG. In this case, the collection system 100 may employ a configuration in which the captured image of the container T captured by the camera 331 itself is used as identification information, or a configuration in which the container information T1 is read from the captured image.

Here, when the container T is cylindrical, the container information T1 is attached to the curved surface, so the container information T1 shown in the captured image is distorted and may not be read as it is. Further, when the container T set in the container holder H is deviated from the predetermined orientation, it can be assumed that the container information T1 appears distorted. Therefore, the collection system 100 may be configured to perform image processing on the container information T1 appearing in the captured image, and read the container information T1 of the container T from the processed captured image. Here, as the image processing, known geometric distortion correction processing (for example, curvature correction processing, etc.) can be applied. By adopting this configuration, the collection system 100 can accurately read the container information T1 of the container T from the captured image.

Further, the captured image of the container T may include the second end P2 of the movement path P, the liquid surface of the sample contained in the container T, and the like. In this case, a configuration may be adopted in which the sampling status of the sample and the amount of the sample that has been sampled are confirmed from the captured image of the container T captured by the camera 331 . Here, the collection status of the sample is intended to mean, for example, uncollected, collected, or the like.

The camera 331 may be capable of capturing moving images. For example, the moving image captured by the camera 331 may show the operation of the container holder H and the state during sampling. In this case, it is possible to monitor the sampling operation, the state of the sample coming out from the second end P2 of the moving path P, and the like, by moving images captured by the camera 331 .

When the housing C and the door portion D of the collection device 1 have a light-shielding property, when the door portion D is closed, the container holder H exists in the light-shielded space (the above-described light-shielding portion). This configuration can prevent the imaging of the container T by the camera 331 from being disturbed by external light. However, in order to image the container T, illumination for illuminating the container T is required. Therefore, as shown in FIG. 3, the housing C may be provided with lighting units 332a and 332b that illuminate the container T to be imaged when the camera 331 images the container T. FIG. In this case, the camera 331 and the illumination units 332 a and 332 b constitute the imaging unit 33 of the sampling device 1 .

When the container T is illuminated and an image is captured by the camera 331, depending on the degree of light reflection, the container information T1 of the container T may not be read, or the liquid surface of the sample in the container T may be difficult to see. can. In such cases, these problems can be resolved by changing the direction of the light that illuminates the container T or by adjusting the intensity of the light. Therefore, the sampling device 1 may include a plurality of illumination units 332a and 332b. FIG. 3 shows a case where two illumination units (illumination units 332a and 332b) are provided. The illumination unit 332a is provided on the ceiling of the housing C and can illuminate the container T from above, and the illumination unit 332b is provided below the camera 331 and can illuminate the container T from below. is. When the camera 331 captures an image of the container T, the sampling device 1 may be able to illuminate the container T from at least one of the illumination unit 332a and the illumination unit 332b. By adopting this configuration, the sampling system 100 can reduce the probability of failure in reading the container information T1 and detecting the water level based on the position of the liquid surface of the sample contained in the container T. Note that the number of illumination units and the arrangement of each illumination unit can be changed as appropriate, and are not limited to this.

Note that the sampling device 1 may include a range sensor for water level detection processing. For example, a TOF (Time of Fright) sensor (not shown) can be applied as such a distance measuring sensor. The TOF sensor includes an emitting portion that projects an ultrasonic wave or an infrared laser pulse toward the container T at the accommodation position, and a light receiving element that receives the ultrasonic wave or the infrared laser. A TOF sensor measures the time required for an ultrasonic wave or an infrared laser to be emitted, reflected by an object to be measured (for example, a liquid surface), and returned to a light-receiving element. The TOF sensor calculates and outputs the distance to the measurement object based on the measured time and the velocity of the ultrasonic wave or infrared laser. When using a TOF sensor for detecting the water level of the sample in the container T, the TOF sensor may be installed on the ceiling of the housing C at a position corresponding to the housing position. Thereby, the TOF sensor can emit an ultrasonic wave or an infrared laser toward the liquid surface in the container T. FIG. The sampling device 1 can identify the position of the liquid surface of the sample in the container T based on the distance output from the TOF sensor, and execute the water level detection process.

Next, the configuration of the holder base B will be described with reference to FIG. FIG. 4 is a diagram showing an example of the configuration of the holder base B. As shown in FIG. FIG. 4 is a top view of the sampling device 1 of FIG.

If an abnormality occurs in the sampling operation of the sampling device 1, a sample that exceeds the capacity of the container T may be discharged, and an event may occur in which the sample overflows from the container T. FIG. Alternatively, the event may occur that the sample exits the second end P2 when the container T is not in the stowed position. Alternatively, an event may occur in which the sample in the container T spills out of the container T due to an earthquake or the like. If such an event occurs, the inside of the sampling device 1 will be contaminated with the sample. Therefore, the upper surface of the holder base B of the sampling device 1 is provided with a groove B1 and a through hole B2 that serve as a flow path for the sample that overflows or spills from the container T. As shown in FIG.

The groove B1 is a concave portion provided on the upper surface of the holder base B. As shown in FIG. It is provided at a position corresponding to each container T held by the container holder H. As shown in FIG. On the other hand, the through hole B2 is a hole that extends from the bottom of the groove B1 to the lower surface of the holder base B. As shown in FIG. Therefore, the sample that has reached the groove B1 can exit the sampling device 1 through the through hole B2. By adopting this configuration, the collection device 1 can avoid contamination of the inside by a spilled or overflowed sample.

(Schematic configuration of sampling device 1)
Next, a schematic configuration of the sampling device 1 will be described with reference to FIG. FIG. 5 is a block diagram showing an example of a schematic configuration of the collection device 1. As shown in FIG. For convenience of explanation, the same reference numerals are given to the same members as those already explained, and the explanation thereof will not be repeated.

The sampling device 1 includes a control section 10 , a storage section 20 and a pump 31 . In addition, the sampling device 1 may further include a container holding section 32 and an imaging section 33 . The control unit 10 is, for example, an MCU (Micro Controller Unit), and controls to execute processing of each function provided in the sampling device 1 . The storage unit 20 is a storage device in which various computer programs read by the control unit 10 and data used in various processes executed by the control unit 10 are stored. The storage unit 20 contains a collection history 21 that indicates the history of sample collection by the collection device 1 . In the following description, the sampling device 1 collects a sample according to a collection instruction acquired from the management system 9. However, the collection device 1 has an input unit (see FIG. not shown). This allows the administrator to directly input the collection instruction to the collection device 1 installed for the object.

The control unit 10 includes an instruction acquisition unit 11 , a collection execution unit 12 , an identification information acquisition unit 13 and a completion report output unit 15 .

The instruction acquisition unit 11 acquires a collection instruction from the management system 9 . Harvest instructions may be entered into management system 9 using remote terminal 5 . The data structure of the collection instruction will be described later (see FIG. 8).

In response to a collection instruction, the collection execution unit 12 stores a sample collected from a target in a container T to which unique container information T1 is assigned in advance. That is, the container information T1 is given to each container T before the sample is accommodated. For example, the collection execution unit 12 controls the driving mechanism of the container holding unit 32 to move the container T to the accommodation position. When the movement of the container T to the accommodation position is completed, the sampling execution unit 12 subsequently controls the pump 31 to move the sample from the object into the container T at the accommodation position.

The identification information acquisition unit 13 acquires container information T1 from the container T containing the sample. The identification information acquiring unit 13 may be configured to acquire the captured image when the container information T1 is shown in the captured image captured by the camera 331 . Alternatively, the identification information acquiring unit 13 may acquire, from a reading device (not shown) capable of reading the container information T1, identification information given to each container T read by the reading device. Note that the reader may be, for example, a QR code reader, a bar code reader, or the like.

The completion report output unit 15 outputs collection completion information including collection time information regarding the collection time when the sample was collected and identification information of the container T containing the sample. For example, the completion report output unit 15 acquires a signal indicating that sample collection is completed from the collection execution unit 12, and the completion report output unit 15 receives the container T containing the sample from the identification information acquisition unit 13. to obtain the identity of The completion report output unit 15 generates collection completion information and outputs it to the management system 9 . The collection completion information is stored in the storage unit 20 as collection history 21 . Collection completion information will be described later (see FIG. 10).

In the case of the collection device 1 having the camera 331 , the control unit 10 has an imaging control unit 14 that controls imaging by the camera 331 . If the sampling device 1 also includes illumination units 332a and 332b, the control unit 10 controls such that the container T is illuminated by at least one of the illumination units 332a and 332b when the camera 331 captures an image of the container T.

(Schematic configuration of management system 9)
Next, a schematic configuration of the management system 9 will be explained using FIG. FIG. 6 is a block diagram showing an example of a schematic configuration of the management system 9. As shown in FIG.

The management system 9 has a control section 90 and a storage section 60 .

The control unit 90 is, for example, a CPU, and controls to execute processing of each function provided in the management system 9 . The control unit 90 includes an instruction output unit 91 , a completion report acquisition unit 92 (reading unit), and a management unit 93 .

The storage unit 60 is a storage device in which various computer programs read by the control unit 90 and data used in various processes executed by the control unit 90 are stored. The storage unit 60 includes a collection instruction 61 , position information 62 and a collection completion information database 63 .

The collection instruction 61 stores a collection instruction to the collection device 1 input from the remote terminal 5 for each collection device 1 to be instructed. The position information 62 is information indicating the target position (that is, the position where the sampling device 1 is installed). A sampling device ID, which is unique identification information, is assigned to each of the sampling devices 1, and the sampling device ID is associated with position information 62 indicating the location where the sampling device 1 is installed. The collection completion information database 63 stores information in which the collection completion information acquired from the collection device 1 and the position information indicating the target position or the collection device ID are associated with each other.

The instruction output unit 91 outputs a collection instruction for collecting a sample to the collection device 1 for collecting a sample from a target into a predetermined container T. FIG.

The completion report acquisition unit 92 obtains collection completion information including collection time information about the collection time when the sample was collected by the collection device 1 and identification information pre-assigned to the container T containing the sample, from the collection device 1. Get from If the completion report includes a captured image of the container T captured at least one of immediately before, during, and after collection, the completion report acquisition unit 92 obtains the identification indicated on the container T. It may have a function as a reading unit for reading information.

The management unit 93 associates the position information indicating the position of the object or the sampling device ID unique to the sampling device 1 with the sampling completion information corresponding to the sampling instruction and stores them in the sampling completion information database 63 .

The management system 9 may be capable of providing the remote terminal 5 with a display screen that prompts the user to enter a collection instruction. In addition, the management system 9 may provide a display screen including the information stored in the collection completion information database 63 to the requesting remote terminal 5 in response to a viewing request from the remote terminal 5 . A display screen for receiving the input of the collection instruction and a display screen for displaying the collection completion information, which are displayed on the display unit of the remote terminal 5, will be described later with specific examples.

(Processing flow of collection system 100)
Next, the processing flow of the collection system 100 will be described using FIG. 7 while referring to FIGS. 8 to 12. FIG. FIG. 7 is a sequence diagram showing the processing flow of the collection device 1 and the management system 9 of the collection system 100. As shown in FIG.

In FIG. 7, first, the management system 9 outputs the collection instruction input by the administrator to the collection device 1 (step S91: collection instruction step). The input collection instruction may be stored in the collection instruction 61 for each collection device 1 that is an instruction target.

<Screen display for accepting input of collection instructions>
FIG. 8 is an example of a screen displayed on the display unit of the remote terminal 5 for receiving an input of a collection instruction. A sampling instruction can be set for each sampling device 1 . Therefore, as shown in FIG. 8, the screen for accepting the input of the sampling instruction has a field R1 for displaying the sampling device ID, a field R2 for inputting the date of sampling, a field R3 for inputting the time of sampling, and a field R3 for inputting the amount of sampling. A column R4 may be included that allows the Further, position information indicating the position where the sampling device 1 is installed corresponding to the sampling device ID (for example, "sewer from facility X", etc.) may be displayed.

As shown in FIG. 8, a column R5 may be provided, and the following information may be displayed in this column R5.
・Map indicating the location where the sampling device 1 is installed ・Information on the specifications and functions of the sampling device 1 assigned the sampling device ID displayed in the column R1 ・List column R1 of sampling instructions input in the past By displaying R5, it is possible to support the input of the collection instruction by the administrator and to input the collection instruction without error. The collection instructions entered at the remote terminal 5 are sent to the management system 9 .

<Data structure of collection instruction 61>
FIG. 9 is a diagram showing an example of the data structure of the collection instruction 61. As shown in FIG. As shown in FIG. 9, the collection instruction 61 stores a collection device ID, a collection date, a collection time, and a collection amount in association with each other.

FIG. 9 shows sampling instructions for the sampling device 1 assigned the sampling device ID [xxxx] and the sampling device 1 assigned the sampling device ID “yyyyy”. For example, the sampling device 1 assigned the sampling device ID [xxxx] is instructed to sample “50 mL” at “daily”, “9:00” and “15:00”. . Also, for the sampling device 1 to which the sampling device ID [yyyyy] is assigned, ``every Monday'', ``100 mL'' at ``7:00'' and ``17:00'', and ``50 mL'' at ``12:00''. It is instructed to collect a sample of

Returning to FIG. 7, the sampling device 1 acquires a sampling instruction (step S11). Then, the sampling device 1 captures an image of the container T at the accommodation position with the camera 331 (step S12). If there is no container T at the accommodation position, the collection device 1 moves the container holder H until the container T is located at the accommodation position.

Next, the collecting device 1 collects a sample in the container T to which unique identification information is assigned in advance according to the obtained collection instruction (step S13: collection execution step).

Subsequently, the sampling apparatus 1 outputs to the management system 9 sampling completion information including sampling time information regarding the sampling time at which the sample was sampled and identification information acquired from the container T containing the sample (Step S14: Completion reporting step).

The management system 9 acquires the collection completion information (step S92), and stores the position information indicating the position of the object or the collection device ID and the collection completion information corresponding to the collection instruction in the collection completion information database 63 in association with each other (step S92). step S93: management step).

<Data structure of collection completion information database 63>
FIG. 10 is a diagram showing an example of the data structure of the collection completion information database 63. As shown in FIG. As shown in FIG. 10, the collection completion information database 63 stores the collection device ID, collection start time, and identification information in association with each other.

FIG. 10 shows the collection completion information obtained from the collection device 1 with the collection device ID [xxxx] and the collection device 1 with the collection device ID “yyyyy”. For example, from the collection device 1 to which the collection device ID [xxxx] is assigned, the fact that collection was started at "9:00" and "15:00" and the identification information are acquired. As the identification information, captured image data obtained by capturing the container information T1 of the container T containing the sample by the camera 331 is acquired.

Note that the sampling device 1 may be configured to output information indicating whether or not an abnormality has occurred in the sampling operation instead of the sampling completion information or attached to the sampling completion information. When information indicating that no abnormality has occurred in the sampling operation is obtained, "OK" is entered as a remark in the sampling completion information database 63, as shown in FIG. On the other hand, when information indicating that an abnormality has occurred in the sampling operation is obtained, "!" is entered. For example, when a "!" It should be noted that the collection system 100 may be configured to transmit a notification of the occurrence of the abnormality to the remote terminal 5 when an abnormality occurs in the collection operation. A notification of the occurrence of an abnormality may be sent as an e-mail or as a message using a social networking service. A notification notifying the occurrence of an abnormality can be sent from the management system 9 to the remote terminal 5, for example.

<Identification Information Unique to Container T>
Here, the configuration of the container T will be described with reference to FIG. 11 . 11A and 11B are diagrams showing an example of the configuration of the container T. FIG. FIG. 11 shows a container T containing a sample.

Individual container information T1 is given to the container T in advance. In FIG. 11, a case where the container information T1 is a QR code will be described as an example, but it is not limited to this, and may be a QR code, barcode, character string display, RFID, or the like.

A female screw portion T2 may be provided in the vicinity of the opening of the container T. The female threaded portion T2 can be screwed with a male threaded portion provided on a predetermined plug (not shown). That is, the container T may be capable of being fitted with a stopper by internal threads T2 to seal the contained sample therein.

Container T may be a transparent or translucent centrifuge tube applicable to the instrument used for sample analysis. For example, container T may be made of polypropylene or polystyrene. Here, the instruments used for sample analysis are intended to include centrifuges, shakers, stirrers, and the like.

If the container T for containing the sample collected from the subject is different from the analysis container (not shown) used for analyzing the sample, the sample must be transferred before analysis. This transfer work is not only troublesome, but also prone to human error because information on the transferred sample and the analysis container used for the transfer work must be accurately recorded. Since the sampling device 1 uses a centrifuge tube or the like that can be used for analysis as the container T, there is no need to transfer the sample, and the risk of human error can be reduced.

The container T may be selected according to the physical properties of the sample collected from the subject. For example, when the sample is a gas, a highly volatile liquid, or the like, a container T capable of containing the gas and the highly volatile liquid in a sealed space (for example, a container T having a hermetic stopper) may be employed. For example, when a container T having a hermetic stopper is employed, the needle provided at the second end P2 penetrates the pierceable portion provided in the hermetic stopper of the container T at the accommodation position, and the sample is transferred to the container T through the needle. It is sufficient to adopt a configuration that is housed inside.

<Display screen for displaying collection completion information>
FIG. 12 is a diagram showing an example of a display screen displaying collection completion information, which is displayed on the display unit of the remote terminal 5. As shown in FIG. Collection completion information is managed for each collection device 1 . As shown in FIG. 12, the screen displaying the collection completion information displays a field R6 for displaying the collection device ID, a field R7 for displaying the collection date, a field R8 for displaying the collection time, and a collection amount. column R9 may be included. Further, position information indicating the position where the sampling device 1 is installed corresponding to the sampling device ID (for example, "sewer from facility X", etc.) may be displayed.

As shown in FIG. 12, a column R10 may be provided in which the picked-up image of the container T included in the collection completion information is displayed. The captured image of the container T captured by the camera 331 may include not only the container information T1 but also the liquid surface (for example, the meniscus) of the contained sample. In this case, an administrator who visually recognizes the display of the collection completion information can easily confirm that the sample collection operation has been properly performed based on the image in the column R10.

The display screen displaying the collection completion information may display information about the collection time for collecting the container T containing the sample. For example, the number of empty containers T set in the container holder H may be displayed. The number of collection completion information acquisition times after the previous collection of the container T containing the sample may be displayed. By adopting this configuration, it is possible to inform the administrator of the timing at which the container T containing the sample should be collected.

When the number of targets is large, or when the targets are far away, monitoring the sample collection operation by the sampling device 1 and managing the collected samples require labor. In addition, for example, mistakes are likely to occur in the work of recording the position of the object and the date and time of collection, and collating the position of the object and the date and time of collection with the container T containing the sample. By adopting the above configuration, based on the identification information given to the container T in advance, the collected sample can be easily managed by associating it with the position of the object, the date and time of collection, and the container T containing the sample. can.

(Modified example: configuration for determining the collection amount from the captured image of the container T)
The collection system 100 may adopt a configuration in which, in addition to reading the identification information of the container T from the captured image of the container T, the appropriateness of the collection amount of the sample is determined. For example, the identification information acquisition unit 13 of the sampling device 1 or the completion report acquisition unit 92 of the management system 9 detects the water level of the sample contained in the captured image of the container T, and determines whether the amount of collection is appropriate. A configuration for making a determination may be adopted. By adopting this configuration, the sampling device 1 itself or the management system 9 can automatically determine whether or not the sampling operation has been performed normally according to the sampling instruction.

(Arrangement example of movement path P)
Next, an arrangement example of the moving paths P will be described with reference to FIG. 13 . FIG. 13 is a schematic diagram showing an arrangement example of the movement path P. As shown in FIG.

The transfer path P is a tube that serves as a passage for the sample collected from the subject to move to the container T. As shown in FIG. As described above, the movement path P has a first end P1 located on the object side from which the sample is collected, a second end located on the container T side from which the collected sample exits toward the container T, have.

A sample that is collected in response to a collection instruction is required to collect a sample that reflects the state of the target at the collection time set in the collection instruction. For example, when the sample is liquid, the sample moves in the movement path P when the sampling device 1 drives the pump 31 . When the amount of sample set in the sampling instruction is stored in the container T, the sampling device 1 stops the pump and ends the sample sampling operation. At this time, if there is a valley where the sample descends and then rises between the first end P1 and the second end P2, the sample gathers and stays in this valley. Old samples remaining in the travel path P can also cause errors in the amount of samples taken in response to a sampling order.

Therefore, in the sampling apparatus 1, as shown in FIG. 13, the sample moving along the movement path P is arranged so as not to have a valley portion (U-shaped or J-shaped portion) where the sample descends and then rises. . As a result, the sample that has entered the moving path P during sample collection returns to the object without remaining in the moving path P. Therefore, when the sampling device 1 collects a new sample in response to a collection instruction, no old sample remains in the moving path P. Therefore, the sampling device 1 can suppress the mixing of an old sample into a newly sampled sample and the occurrence of an error in the amount of sampling.

(Co-wash function)
For example, when collecting a sample of a liquid to be subjected to high sensitivity analysis, the collection amount may be small. However, when the collection amount is small, the influence of the contamination of old samples remaining on the movement path P on the analysis results cannot be ignored. Therefore, the sampling device 1 may perform a co-washing operation for co-washing the moving path P before the sampling operation. A processing flow of a collection system 100 employing such a collection device 1 will be described with reference to FIG. FIG. 14 is a sequence diagram showing the processing flow of the collection device 1 and the management system 9 of the collection system 100. As shown in FIG. For convenience of explanation, the same processes as already explained are given the same reference numerals, and the explanation thereof will not be repeated.

In FIG. 14, the sampling apparatus 1 acquires a sampling instruction (step S11), and when the container T at the accommodation position is imaged (step S12), the sampling execution unit 12 executes the co-washing operation (step S12a), and then A sample is collected in container T at .

The sampling execution unit 12 of the sampling device 1 that has acquired the sampling instruction first drives the pump 31 before the sampling time set in the sampling instruction to fill the moving path P with the liquid that has been sampled from the object. After that, the sampling execution unit 12 drives the pump 31 in the reverse direction to return the liquid filling the movement path P to the object. The action of repeating this several times is the "co-washing action".

The sampling executing unit 12 controls the pump 31 so that the sample does not come out from the second end P2 of the movement path P during the co-washing operation. For example, the sampling device 1 may be preset with the volume of liquid required to fill the movement path P from the first end P1 to the second end P2. In this case, the sampling execution unit 12 may control the pump 31 driven in the co-washing operation so that the volume of liquid less than the volume required to fill the movement path P moves from the object into the movement path P. Alternatively, the sampling device 1 may comprise a sensor (not shown) near the second end P2. In this case, the sampling execution unit 12 may stop the pump 31 and drive it in the reverse direction when the liquid filling the movement path P is detected by the sensor. With this configuration, it is possible to prevent the sample from being unintentionally accommodated in the container T during the co-washing operation.

[Embodiment 2]
When the sample to be collected from the object is a liquid, the sample moved from the object to the movement path P may be mixed with air bubbles. Air bubbles in the movement path P cause an error in the amount of sample collected by the sampling device 1 . Therefore, the collection device 1 may be equipped with a function of detecting air bubbles in the movement path P. FIG.

(Configuration of sampling device 1A)
A sampling device 1A having a function of detecting air bubbles will be described with reference to FIG. FIG. 15 is a block diagram showing an example of a schematic configuration of a collection device 1A according to Embodiment 2 of the present invention. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

The sampling device 1A includes a control unit 10A, a storage unit 20, a pump 31, a container holding unit 32, an imaging unit 33, and an air bubble detection unit . The control unit 10A includes an instruction acquisition unit 11, a sampling execution unit 12A, an identification information acquisition unit 13, an imaging control unit 14, and a completion report output unit 15.

The air bubble detection unit 34 detects air bubbles in the sample moving along the movement path P at any position on the movement path P. FIG. More specifically, the air bubble detection unit 34 is installed between the first end P1 and the second end P2 of the movement path P, and detects a state in which liquid in the movement path P is not detected (that is, air bubbles). The air bubble detection unit 34 may be an ultrasonic sensor, although not limited to this.

For example, in the sampling device 1A, when the volume of liquid required to fill the movement path P from the first end P1 to the second end P2 is set in advance, the sampling execution unit 12A sets the sampling instruction to The pump 31 is driven only for the time required to accommodate the collection amount of the sample in the container T. Then, as shown in FIG. If there is a period during which the air bubble detection unit 34 detects air bubbles, the sampling execution unit 12A may increase the time for driving the pump 31 by the length of the period. As a result, the sampling device 1A can sample the amount of sample set in the sampling instruction into the container T without being affected by air bubbles.

[Embodiment 3]
For example, when a peristaltic pump is employed as the pump 31, the size of the sample moving along the movement path P depends on the height difference between the first end P1 and the second end P2 of the movement path P, the length of the movement path P, and the like. different flow velocities. When the sampling device 1 is installed for each of a plurality of objects, the administrator determines the volume of liquid required to fill the movement path P from the first end P1 to the second end P2, where each sampling device 1 is installed. You have to check and set for each object. Therefore, the sampling device 1 may be equipped with a calibration function that automatically measures the volume of liquid required to fill the movement path P from the first end P1 to the second end P2.

A sampling device 1B having a calibration function will be described with reference to FIG. FIG. 16 is a block diagram showing an example of a schematic configuration of a collection device 1B according to Embodiment 3 of the present invention. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

The sampling device 1B includes a control section 10B, a storage section 20B, a pump 31, a container holding section 32, and an imaging section 33. The control unit 10B further includes a moving route characteristics measuring unit 16 in addition to the instruction acquiring unit 11, the collection executing unit 12B, the identification information acquiring unit 13, the imaging control unit 14, and the completion report output unit 15. The traveling route characteristic measuring unit 16 sets the traveling route characteristic indicating the time required for the sampling execution unit 12B to fill the traveling route P with samples or the collection amount of samples required for filling the traveling route P with samples. measured before getting the first sampling order. The measured travel path characteristics are stored in the travel path characteristics 22 of the storage unit 20B.

The collection executing unit 12B collects an amount of sample obtained by adding the amount of the measured movement path characteristic to the collection amount indicated in the collection instruction, and collects the amount of sample indicated in the collection instruction in the container. Housed in T. As a result, it is possible to save the trouble of measuring the movement path characteristics of each sampling device 1B installed in the object and setting them in the sampling device 1B, so that it is possible to reduce the amount of work when installing the sampling device 1B.
