Description

[Technical Field]

[0001] The present invention relates to an analysis system and an analysis device. [Background technology]

[0002] Conventionally, various analytical devices are provided with a display unit that displays various information related to analysis. For example, Japanese Patent Application Laid-Open No. 2023-124605 (Patent Document 1) discloses a preparative liquid chromatograph having a display unit that displays analysis results. Furthermore, when performing analysis using an analytical device, an operator requires various pieces of information. For example, Japanese Patent Application Laid-Open No. 2020-038199 (Patent Document 2) discloses an analytical procedure manual, which is composed of paper documents or text data and serves as information that an operator refers to when performing chromatographic analysis using a chromatograph device.

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-124605 [Patent Document 2] Japanese Patent Application Publication No. 2020-038199 Summary of the Invention [Problem to be solved by the invention]

[0004] An operator may wish to view the information displayed on the display unit at a location away from the analyzer. For example, an operator may wish to share analysis results with others in various situations. To accommodate such situations, in an analysis system, it is preferable that the conventional display unit be configured as a display device separate from the main body of the analyzer.

[0005] On the other hand, there are cases where an operator wishes to refer to the information displayed on the display unit near the analyzer. For example, there are cases where an operator wishes to immediately refer to the analysis results while watching the operation of the analyzer near the analyzer. In such cases, simply configuring the display unit separately from the main body of the analyzer is likely to result in a dangerous situation. More specifically, there are cases where various chemical containers are placed around the analyzer, and if the display unit is placed among the chemical containers, there is a concern that the display unit may cause a container to tip over.

[0006] The present invention has been devised in view of the above circumstances, and its purpose is to provide a technique for safely displaying information related to analysis in an analysis system. [Means for solving the problem]

[0007] An analysis system according to one aspect of the present disclosure comprises an analysis device having elements used in an analysis operation and a display device that displays information related to the analysis operation, the display device being configured separately from the analysis device, and the analysis device having a holding portion for holding the display device.

[0008] An analytical device according to one aspect of the present disclosure is an analytical device having elements used in analytical operations, comprising a communication unit for communicating with a display device that displays information about the analytical operations, and a holding unit that is configured separately from the display device and for holding the display device. [Effects of the Invention]

[0009] According to one aspect of the present disclosure, techniques are provided for securely displaying information about an analysis in an analysis system. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated.

[0012] [Analysis system configuration] 1 to 6 each show an external view of an analysis system 1 according to an embodiment of the present disclosure. Analysis system 1 includes an analysis device 100 and a terminal device 200 capable of communicating with analysis device 100.

[0013] 1, the analytical system 1 includes an analytical device 100. The analytical device 100 has a protective frame 110 on its top surface, a door 120 on its front surface, and a drawer 140 on its bottom surface. The drawer 140 can accommodate elements such as a solvent container.

[0014] As shown primarily in FIGS. 2, 3, and 6, door 120 is configured to slide in the vertical direction (the direction indicated by double-headed arrow A1). Door 120 opens and closes the opening of storage unit 130 by sliding. Door 120 is an example of a shielding member that covers the opening of storage unit 130. Because door 120 slides vertically, even if another device is installed next to analysis device 100, door 120 can open and close the opening without interfering with the operation of the other device. Although omitted in FIGS. 2, 3, and 6 for convenience of explanation, storage unit 130 houses elements used in the analysis operation of analysis device 100.

[0015] An example of the analytical device 100 is a liquid chromatograph. An example of such an element is a pump that supplies a solvent (mobile phase) to the analytical flow path. Another example of such an element is an autosampler that injects a sample into the analytical flow path. Another example of such an element is a column oven that adjusts the temperature of the column. Another example of such an element is a detector (such as an ultraviolet-visible spectroscopic detector or a fluorescence spectroscopic detector) for detecting one or more components separated from the sample in the column.

[0016] As primarily shown in FIG. 4 , the analyzer 100 has a link mechanism for sliding the door 120 in the vertical direction. The link mechanism includes arms 141, 142, 144, and 145 and bases 143 and 146. One end of each of the arms 141 and 142 is connected to the base 143. The other end of each of the arms 141 and 142 is connected to the frame of the storage unit 130. One end of each of the arms 144 and 145 is connected to the base 146. The other end of each of the arms 144 and 145 is connected to the frame of the storage unit 130.

[0017] As primarily shown in FIG. 5, door 120 includes a main body 121 and a cover 122. Cover 122 opens and closes the front of main body 121 by rotating in the direction indicated by double-headed arrow A2. Cover 122 has a handle 122A on the left end and a handle 122B on the right end. An operator can rotate cover 122 by holding handles 122A and 122B. A window 122C is disposed between handles 122A and 122B.

[0018] The main body 121 has protrusions 123, 124, and 125. In the state shown in Fig. 5 (a state in which the door 120 closes the opening of the storage section 130), the protrusions 123 and 124 extend vertically, and the protrusion 125 extends horizontally. The door 120 holds the terminal device 200 by the protrusions 123, 124, and 125. An example of the terminal device 200 is a tablet terminal.

[0019] In one implementation example, the size of the window 122C is equal to or smaller than the size of the outer edge of the terminal device 200. That is, the window 122C may have the same shape as the outer edge of the terminal device 200, thereby making the entire terminal device 200 visible from the outside, or may cover a portion of the terminal device 200. The window 122C may be, for example, a transparent sheet. This makes the terminal device 200 visible from the outside and prevents reagent from adhering to the terminal device 200. Instead of the window 122C, a hole may be formed in the cover 122. That is, the portion corresponding to the window 122C may be hollow. This allows the operator to view the display on the display 260 of the terminal device 200 from outside the cover 122 when the cover 122 is closed over the front of the main body 121.

[0020] In the analysis system 1, it is sufficient that the terminal device 200 can be seen from outside the cover 122 through the window 122C. That is, the outer edge of the window 122C may be larger than the outer edge of the terminal device 200. If a hole is formed instead of the window 122C, the terminal device 200 may be held by the door 120 by being fitted into the hole. In this case, the terminal device 200 is held by the hole formed in the door 120 (cover 122).

[0021] 6, the terminal device 200 is detachable from the analysis device 100. This allows the operator to use the terminal device 200 at a location away from the analysis device 100.

[0022] [Hardware configuration of the analysis system] 7 is a diagram showing the hardware configuration of the analysis system 1. The hardware configurations of the analysis device 100 and the terminal device 200 will be described with reference to FIG.

[0023] (Analyzer 100) The analysis device 100 includes a control unit 150 , a communication interface 151 , a memory 152 , a driving unit 153 , a detection unit 154 , an output interface 160 , and an input interface 170 .

[0024] Control unit 150 is realized by, for example, one or more processors, and executes calculations for controlling the operation of analysis device 100. Communication interface 151 is realized by, for example, a network card, and functions as a communication interface between analysis device 100 and terminal device 200. Memory 152 non-temporarily stores programs and / or data for the above calculations.

[0025] The driving unit 153 includes one or more elements (e.g., a pump) that are driven for the analytical operation in the analytical device 100. The detection unit 154 includes one or more elements (e.g., the detectors described above) that perform the detection operation related to the analytical operation in the analytical device 100.

[0026] The output interface 160 is realized by, for example, a display and / or a lamp, and outputs the calculation results of the control unit 150. The input interface 170 is realized by, for example, an operation button and / or a touch sensor, and accepts operations from the outside.

[0027] (Terminal device 200) The terminal device 200 includes a control unit 250 , a communication interface 251 , a memory 252 , a display 260 , and an input device 270 .

[0028] The control unit 250 is realized by, for example, one or more processors, and executes calculations for controlling the operation of the terminal device 200. The communication interface 251 is realized by, for example, a network card, and functions as a communication interface between the terminal device 200 and the analysis device 100. The memory 252 non-temporarily stores programs and / or data for the above calculations.

[0029] Display 260 may be any type of display, such as a TFT (Thin Film Transistor) liquid crystal display or an organic EL (Electro Luminescence) display. Display 260 may also be an electronic paper display. There are no particular limitations on the size of display 260, and for example, A4 size (210 mm × 297 mm) may be adopted.

[0030] The input device 270 is realized by, for example, an operation button and / or a touch sensor, and accepts an operation from the outside.

[0031] [Linkage between analytical devices and terminal devices in analytical systems] The analysis apparatus 100 performs an analysis operation in accordance with instructions input to the input interface 170. The analysis apparatus 100 also performs an analysis operation in accordance with instructions input via the communication interface 151. That is, the analysis apparatus 100 can perform an analysis operation in accordance with instructions input from the terminal apparatus 200. This allows the operator to cause the analysis apparatus 100 to perform an analysis operation by operating the input device 270 of the terminal apparatus 200.

[0032] 8 is a diagram showing a first modified example of the analysis system 1. In the example of FIG. 8, the analysis device 100 further includes a charging pad 181 and a switch 182 on the main body 121 of the door 120.

[0033] When terminal device 200 is held by protrusions 123, 124, and 125 (set on door 120) as shown in Fig. 5, switch 182 is pushed into protrusion 124. Analytical device 100 further includes a sensor that detects whether switch 182 is in a state where it is not pushed into protrusion 124 (Fig. 8) or a state where it is pushed into protrusion 124 (Fig. 5). Switch 182 and the above sensor constitute an example of a detection member that detects that a display device is held in the holding section.

[0034] The control unit 150 of the analysis device 100 may control the analysis device 100 to perform an analysis operation (to operate the drive unit 153 for the analysis operation) according to an instruction from the terminal device 200, on the condition that the switch 182 is pressed into the protrusion 124. For example, when the control unit 150 receives an instruction from the terminal device 200, if the sensor detects that the switch 182 is pressed into the protrusion 124, the control unit 150 operates the drive unit 153 according to the instruction, but if the sensor detects that the switch 182 is not pressed into the protrusion 124, the control unit 150 ignores the instruction. This allows the operator to send an instruction for an analysis operation to the analysis device 100 via the terminal device 200, on the condition that the terminal device 200 is set in the door 120, and can prevent the analysis device 100 from becoming inoperable due to conflicting instructions from multiple terminal devices.

[0035] The control unit 150 of the analysis device 100 can transmit information related to the analysis operation to the terminal device 200 via the communication interface 151. The information related to the analysis operation can include information identifying the operator who issued the instruction for the analysis operation, settings related to the operation of the drive unit 153, and the detection results of the detection unit 154.

[0036] The control unit 250 of the terminal device 200 displays on the display 260 information relating to the analysis operation received from the analysis device 100 and information received from devices other than the analysis device 100 .

[0037] That is, in the analysis system 1, information relating to the analysis operation of the analysis device 100 is displayed on the terminal device 200 configured separately from the analysis device 100, and the analysis device 100 has a holding portion (protrusions 123, 124, 125, holes formed in the cover 122, etc.) for holding the terminal device 200. This allows the operator to refer to information relating to the analysis operation whether they are in a location distant from the analysis device 100 or in the vicinity of the analysis device 100, and also prevents the terminal device 200 from knocking over a container placed near the analysis device 100.

[0038] If the display 260 is an electronic paper display, the display 260 may continue to display the information related to the analysis operation even when the terminal device 200 is powered off. For example, when the control unit 250 receives a notification from the analysis device 100 that a specific consumable is running low, the control unit 250 displays the notification on the display 260. If the display 260 is implemented as an electronic paper display, the notification of the low level of the specific consumable may continue to be displayed on the display 260 even when the terminal device 200 is powered off. Furthermore, if a worker inputs a message to another worker into the input device 270, the control unit 250 displays the message on the display 260. If the display 260 is implemented as an electronic paper display, the message may continue to be displayed on the display 260 even when the terminal device 200 is powered off.

[0039] The analytical device 100 may have a mechanism for receiving power from a wall outlet and wirelessly charging the terminal device 200. The mechanism includes a charging pad 181. When the terminal device 200 is set on the door 120, power is supplied from the analytical device 100 to the terminal device 200 via the charging pad 181. This allows wireless charging of the terminal device 200.

[0040] 1, the outer edge of the terminal device 200 is covered with the cover 122, creating a sense of unity between the analysis device 100 and the terminal device 200. This makes it difficult for a third party to assume that the terminal device 200 is separate from the analysis device 100, that is, that the terminal device 200 is configured to be detachable from the analysis device 100. This makes it difficult for a third party to assume that the terminal device 200 will be taken away, reducing the possibility of theft of the terminal device 200.

[0041] FIG. 9 is a diagram showing a second modified example of the analysis system 1. In the example of FIG. 9, the cover 122 is provided with an electronic lock 183 for restricting opening and closing of the cover 122. The personal identification number of the electronic lock 183 is known only to specific workers. The electronic lock 183 can more reliably prevent the terminal device 200 from being taken away. The electronic lock 183 is an example of a locking mechanism that restricts the release of the state in which the cover covers the terminal device 200. The locking mechanism may be realized in other ways, for example, by a key and a cylinder having a keyhole.
