[0056] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present utility model belong to the scope of protection of the present utility model.

[0057] The present utility model provides an extraction device, which is provided with: at least one target position capable of placing a reagent kit and positioning marks respectively corresponding to the target positions, the positioning marks being used to determine the reagent kit corresponding to the target position; and

[0058] a camera, the camera being used to take a photo of the reagent kit at the target position to obtain a first target image, the first target image being used to determine whether the position and / or information of the reagent kit is correct.

[0059] For the above extraction device, when placing the reagent kit into the extraction device, it is necessary to first determine the target position where the reagent kit is placed through the positioning marks, and then the camera can take a photo of the reagent kit to obtain a first target image. Since the first target image can be used to judge whether the position and / or information of the reagent kit is correct, as long as the reagent kit is placed into the extraction device, it is possible to determine whether the reagent kit is the designated reagent kit according to the information in the first target image, thus ensuring the smooth progress of subsequent operations.

[0060] The structure of the extraction device will be described in detail below. As Figures 1 to 5 shown, the extraction device includes a working cavity 1, and the working cavity includes an upper housing 11, a lower housing 12, and a left housing 13 and a right housing 14 respectively connected to the upper housing 11 and the lower housing 12;

[0061] At least one target position 3 capable of placing a reagent kit 2 and positioning marks 4 respectively corresponding to the target positions are provided on the lower housing 12, and the positioning marks 4 are used to determine the reagent kit 2 corresponding to the target position 3;

[0062] A camera 5 is provided on one of the upper housing, the left housing, and the right housing, and the camera 5 is used to take a photo of the reagent kit at the target position to obtain a first target image, the first target image being used to determine whether the position and / or information of the reagent kit is correct.

[0063] In the above structure, due to the provision of the target position and the positioning marks, the camera can be arranged at other positions capable of obtaining the first target image. This structural design enables the user to accurately place the reagent kit in place, more conveniently enables the camera to obtain the first target image, and thus more conveniently determines whether the reagent kit is the designated reagent kit.

[0064] In one embodiment, as Figure 2 shown, a label 6 is provided on the reagent kit 2, and the camera 5 is specifically used to take a photo of the label 6 on the reagent kit 2 to obtain the first target image.

[0065] The acquisition of the first target image is based on the label on the kit. The specific situation of the label will be further described in the following embodiments. Specifically, reference can be made to the further description of the label later.

[0066] By setting the label 6 on the kit 2, it is more convenient to obtain the first target image. Specifically, only need to place the kit at the corresponding target position 3 based on the positioning mark 4, and then the camera 5 takes a picture of the label 6 on the kit 2 to form the first target image.

[0067] In one embodiment, two target positions for placing the kit and two positioning marks respectively corresponding to the target positions are provided on the lower housing 12.

[0068] Setting two target positions and two corresponding positioning marks 4 on the lower housing 12 is one of the best implementation methods in this embodiment. Since two target positions 3 can correspond to placing two kits 2, the positioning mark 4 needs to determine the specific kits 2 placed at the two target positions 3 to avoid misplacing the kits. In this way, after placing the two kits, the camera in the extraction device can take pictures of the labels of the two kits to form the first target image, and the first target image can be used to determine whether the positions and / or information of the two kits are correct, thereby improving the usage efficiency of the camera, and judging two kits at one time also improves the judging efficiency of the kits.

[0069] In one embodiment, the positioning mark 4 on the lower housing 12 is located in front of the target position 3, and the positioning mark includes at least one of numbers, letters, and graphics.

[0070] As Figure 1 shown, when the user operates the extraction device, it is necessary to be able to intuitively determine the placement position of the kit. Therefore, the user needs to be able to directly see the positioning mark 4. In this embodiment, the positioning mark 4 is located in front of the target position 3. When the user operates, the positioning mark is closer to the user, and the user can directly see the positioning mark, and then directly and quickly determine the target position of the kit, thereby improving the placement efficiency of the kit.

[0071] The positioning mark can be at least one of numbers, letters, and graphics. For example, Figure 1 the numbers "1" and "2" shown in

[0072] In one embodiment, the camera is located on the upper housing, and the center point of the camera is perpendicular to the middle dividing line of the two kits so that the photographing range of the camera completely covers part or all of the labels on the two kits to obtain the first target image.

[0073] AsFigure 4 As shown, it is a preferred implementation of this embodiment to locate the camera on the upper housing. Figure 4 The photographing range of the camera is shown, which can completely cover part or all of the labels on the two reagent kits. Thus, the camera can photograph the labels of the two reagent kits at one time, so that the first target image can include the labels of the two reagent kits at the same time. Thus, through the first target image, it can be directly determined whether the positions and / or information of the two reagent kits are correct, thereby improving the judgment efficiency.

[0074] In one embodiment, the extraction device further includes:

[0075] A controller, which is communicatively connected to the camera, is configured to obtain the first target image captured by the camera and determine whether the position and / or information of the reagent kit is correct through the first target image.

[0076] The controller in the extraction device can judge the first target image in real time to determine whether the position and / or information of the reagent kit is correct. If the position is correct, the extraction device can perform the next step. If the position is incorrect, it means that the reagent kit needs to be repositioned. Similarly, if it is controlled to judge that the information of the reagent kit is correct, the extraction device can perform the next step. Otherwise, it means that the information of the reagent kit does not conform, and the reagent kit needs to be reselected. The information of the reagent kit can include the category of the reagent kit, such as "Plasmid Automatic Extraction Kit", "Nucleic Acid Extraction Kit", "Protein Extraction Kit", etc., and can also include different information such as the manufacturer of the reagent kit. This embodiment does not list all the information of the reagent kit one by one. The information of different reagent kits can be different, and it can also include various information such as the production date.

[0077] In one embodiment, the extraction device further includes a magnetic bar and a magnetic bar sleeve. The camera is further configured to obtain a second target image of the magnetic bar inserted into the magnetic bar sleeve, and the second target image is used to determine whether the magnetic bar is inserted into the magnetic bar sleeve.

[0078] The extraction device of this embodiment can be a nucleic acid extractor, etc. Its internal can include components such as a magnetic bar and a magnetic bar sleeve. When the magnetic bar and the magnetic bar sleeve are working, there is a relatively important process, which is to insert the magnetic bar into the magnetic bar sleeve. Moreover, the magnetic bar needs to be inserted to the bottom of the magnetic bar sleeve. The camera can photograph the process of the magnetic bar inserted into the magnetic bar sleeve to determine whether the magnetic bar is inserted into the magnetic bar sleeve and the insertion depth, so as to determine whether the combination of the magnetic bar and the magnetic bar sleeve can perform subsequent work perfectly. Therefore, in this embodiment, the monitoring of the magnetic bar inserted into the magnetic bar sleeve can be realized through the second target image to ensure the smooth combination of the two.

[0079] In one embodiment, after the magnetic rod is inserted into the magnetic rod sleeve, the camera is further configured to acquire a third target image of the movement of the magnetic rod along with the magnetic rod sleeve, and the third target image is used to determine whether there is any abnormality when the magnetic rod moves along with the magnetic rod sleeve.

[0080] When the magnetic rod moves along with the magnetic rod sleeve, if an error occurs during operation, it will affect the extraction device. Therefore, it is necessary to promptly confirm whether an error occurs in the movement of the magnetic rod along with the magnetic rod sleeve. In this embodiment, the camera can take a picture of the movement of the magnetic rod along with the magnetic rod sleeve to generate a third target image, and through the third target image, it can be confirmed in real time whether there is any abnormality when the magnetic rod moves along with the magnetic rod sleeve, so as to ensure the normal operation of the extraction device, and when there is an abnormality, the device operation can be stopped in time.

[0081] In one embodiment, the camera includes a recording unit, and the recording unit is configured to record the sound during the operation of the extraction device when the extraction device is working, and the recording is used to determine whether there is any abnormal sound in the extraction device, and further determine whether there is any abnormality in the extraction device through the abnormal sound when there is an abnormal sound.

[0082] Although the extraction device is equipped with a camera, the photographing range of the camera is limited and cannot photograph all positions inside the extraction device. Therefore, it is impossible to avoid abnormalities occurring in other positions that cannot be photographed. Therefore, a recording unit can be set on the camera to record the sound during the operation of the extraction device. If an abnormal sound is recorded, it indicates that the extraction device is operating abnormally, and at this time, the work needs to be temporarily stopped to handle the abnormality. Thus, in this embodiment, it can be determined in real time whether the extraction device is operating abnormally through recording, so as to jointly monitor the operation of the extraction device with the camera and improve the efficiency of detecting abnormalities in the operation of the extraction device.

[0083] In one embodiment, a track for the movement of the camera is correspondingly provided on one of the upper housing, the left housing, and the right housing, and the camera can move along the track to acquire corresponding target images.

[0084] To facilitate the camera to take pictures, a track can be set on the corresponding housing where the camera is installed. The camera can slide on the track, so that the camera can take pictures at different positions, thereby more conveniently acquiring the above-mentioned first target image, second target image, third target image, and other target images. Thus, the extraction device can be better monitored through the camera, work abnormalities can be promptly discovered, and the normal operation of the extraction device can be ensured.

[0085] This embodiment also provides a label applicable to a kit. The kit is applicable to the extraction device as described above, that is, the kit can be placed into the above extraction device to implement the technical solutions related to the content of the above extraction device.

[0086] The label 6 includes a pasting part 61 and an identification part 62. The identification part 62 is used to determine whether the position and / or information of the kit is correct.

[0087] The pasting part 61 can be pasted to the outside of one side of the kit. When the pasting part is pasted to the outside of one side of the kit, the identification part 62 can enable a camera to take a photo of the identification part to obtain a first target image. Preferably, when in use, the identification part can be perpendicular to the pasting part and in a horizontal state. Further, the identification part can be folded and unfolded relative to the pasting part to the horizontal state.

[0088] When using the above label, it is necessary to paste the pasting part to the outside of one side of the kit. At this time, the identification part is perpendicular to the pasting part and in a horizontal state. In this state, after the kit is placed into the extraction device, the identification part can enable the camera in the extraction device to take a photo of the identification part to obtain a first target image. Further, it can be determined whether the kit is the designated kit from the information in the first target image, so as to ensure the smooth progress of subsequent operations.

[0089] Among them, the pasting part 61 can contain relevant information descriptions about the kit, such as the type of the kit, including plasmid automatic extraction kit, nucleic acid automatic extraction kit, etc.; the pasting part can also include the description of the extraction method, such as whether it is magnetic bead method extraction, etc., and other descriptions, such as whether it is in deep well plate packaging, etc.; the pasting part can also include various information such as production date, production number, manufacturer identification, etc. The specific information can be set according to requirements.

[0090] In one embodiment, the identification part 62 on the label includes a position identification area 621 and an information identification area 622.

[0091] The position identification area 621 corresponds to the positioning mark 4 and is used to determine the kit corresponding to the target position on the lower housing.

[0092] The information identification area 622 is used for the camera to obtain a first target image. Preferably, the photographing range of the camera completely covers the information identification area in the identification part of the label on at least one kit to obtain the first target image. Preferably, the photographing range of the camera completely covers the information identification area in the identification parts of the labels on two kits to generate the first target image. Preferably, the first target image obtained by the camera is used to feedback whether the information identification area it contains is missing or incomplete, so as to determine whether the position of the kit is correct.

[0093] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the position identification area 621 also contains the numbers "1" and "2", which match the positioning mark 4, that is, the position identification areas 621 containing the same numbers match the positioning mark 4. It only needs to place the kit at the target position determined by the corresponding positioning mark. It should be noted that using matching numbers for the position identification area and the positioning mark is only a preferred technical solution in this embodiment, and this embodiment is not limited to other ways.

[0094] The information identification area can be covered by the photographing range of the camera to obtain the first target image. When the information identification area obtained from the first target image is missing or incomplete, it means that the incorrect position of the kit causes this situation. Therefore, the user can be prompted to adjust the position of the kit in time.

[0095] As described above, the above label can determine the position of the kit through the position identification area, quickly and correctly place the kit into the extraction device. Through the information identification area, the camera of the extraction device can obtain the first target image to determine whether the position and / or information of the kit is correct, so as to ensure the correct position of the kit in time and thus the working efficiency of the extraction device.

[0096] In one embodiment, the position identification area 621 contains identification characters, and the identification characters include at least one of numbers, letters, and graphics. The identification characters correspond to the positioning mark and are used to determine the kit placed at the target position on the lower housing, so that the information identification area corresponding to the identification characters can be completely covered by the photographing range of the camera.

[0097] As Figure 2As shown, the identification characters included in the position identification area 621 are numbers, which is just one implementation manner of this embodiment, and other forms are also within the protection scope of this embodiment. The identification characters correspond to the positioning marks, and the two need to be consistent, so that users can quickly determine the target position of the kit. When the camera in the extraction device takes a picture, it needs to completely cover the information identification area corresponding to the identification characters, so as to facilitate the camera to obtain the first target image and quickly confirm whether the position and / or information of the kit is correct.

[0098] In one embodiment, the positions of the position identification area and the information identification area on the identification part are as follows:

[0099] The position identification area 621 is located on the left side of the identification part, and the information identification area 622 is located on the right side of the identification part; or

[0100] The position identification area 621 is located on the right side of the identification part, and the information identification area 622 is located on the left side of the identification part.

[0101] As Figure 2 shown, Figure 2 In the left label, the position identification area 621 is located on the left side of the identification part, and the information identification area 622 is located on the right side of the identification part. Specifically, Figure 2 The position identification area "①" in the left label is on the left, and the information identification area two-dimensional code is on the right. Figure 2 In the right label, the position identification area 621 is located on the right side of the identification part, and the information identification area 622 is located on the left side of the identification part. Specifically, Figure 3 The position identification area "②" in the right label is on the right, and the information identification area two-dimensional code is on the left.

[0102] After the above settings, as Figure 3 shown, the two-dimensional codes on the two labels of the two kits can be obtained by the camera in the extraction device in one-time photographing. As Figure 4 shown, it shows the state where the photographing ranges of the two two-dimensional codes include both at the same time, so that the first target image obtained by the camera can obtain the two two-dimensional codes at one time, so as to judge the positions and / or information of the two kits, which not only improves the photographing efficiency, but also improves the judgment efficiency, and is beneficial to the extraction device to improve the work efficiency.

[0103] Among them, the information identification area includes at least one of a two-dimensional code, a bar code, and an identification pattern. By identifying the information identification area, corresponding information can be obtained, such as information about the manufacturer of the kit, the extraction type, the throughput of the kit, etc. From this information, it can be determined whether the kit is the specified kit. All this information can be stored in the two-dimensional code, bar code, identification pattern, etc. in the information identification area. Further, since the first target image has an information identification area, therefore, this information can be obtained through the first target image to determine the kit.

[0104] Figure 2 , Figure 3 , Figure 4 and Figure 5 The implementation scheme that the information identification area shown in includes only a two-dimensional code is a relatively optimal implementation of this embodiment, and this embodiment is not limited thereto. Different information identification areas can be applied to different kits and corresponding extraction devices. The diversification of the information identification area is also beneficial for different extraction devices to implement the above technical solutions of this embodiment, thereby improving work efficiency.

[0105] For example Figure 2 and Figure 3 As shown, this embodiment also provides a kit 2 applicable to the extraction device as described above. The kit is provided with a label 6 as described above. The label 6 corresponds to the positioning mark 4 and is used to determine the kit corresponding to the target position and for the camera to obtain the first target image.

[0106] In this embodiment, when the kit is placed on the extraction device, the label on the kit can be matched with the positioning mark. If they match, the target position where the kit needs to be placed can be determined. At the same time, the camera can take a picture of the label to obtain the first target image. From the first target image, it can be determined whether the position and / or information of the kit is correct, thus ensuring the smooth progress of subsequent operations.

[0107] Among them, the label on the kit is matched with the positioning mark. As Figures 2 to 5 shown, that is, the position identification area "①" on the label is matched with the positioning mark "1", and the position identification area "②" on the label is matched with the positioning mark "2". From the matching result, the kit can be placed at the corresponding target position. Then, the camera can take a picture of the label to obtain the first target image. Taking a picture of the label means taking a picture of the two-dimensional code in the information identification area on the label. As Figures 2 to 5As shown, after the two kits are placed opposite to each other, the two-dimensional codes in the information identification areas on the two labels are completely within the photographing range of one camera. Therefore, the first target image can include the two-dimensional codes in the two information identification areas at the same time, thereby improving the photographing efficiency. Of course, the camera can also take pictures twice, obtaining the two-dimensional code of only one information identification area each time.

[0108] Wherein, the label is located on the side or the upper part of the kit.

[0109] As Figure 2 shown, it shows that the label 6 is located on the side of the kit. Specifically, the label 6 is located on the side with a relatively longer length. The label can also be located on the upper part of the kit. It should be noted that Figure 2 the shape and structure of the label in are one when the label is located on the side. When the label is located on the upper part, the shape and structure of the label can be changed accordingly as long as it can implement the technical solution of this embodiment.

[0110] This embodiment also provides an extraction system, and the extraction system includes:

[0111] The extraction device as described above; and

[0112] The kit as described above that can be placed in the extraction device;

[0113] The kit is provided with the label as described above.

[0114] In the extraction system, the kit is provided with a label. When the kit is placed in the extraction device, the positioning mark in the extraction device and the recognition part on the kit label are matched, and the target position of the kit placed in the extraction device can be determined. After that, the camera in the extraction device can take pictures of the recognition part on the label to obtain the first target image, and the information in the first target image can be used to determine whether the kit is the specified kit, thereby ensuring the smooth progress of subsequent operations.

[0115] The extraction device includes a controller for obtaining relevant information of the kit according to the first target image to confirm at least one of the following information: the authenticity of the kit, whether it is the required kit, and whether the position of the kit is correct.

[0116] The controller can obtain the first target image transmitted by the camera and obtain the information therein. The above authenticity of the kit, whether it is the required kit, and the position of the kit are only part of the information, and it can also include information such as the manufacturer of the kit, the extraction type, and the kit throughput. Thus, after the kit is placed in the extraction device, the extraction device can directly determine various information of the kit, such as whether it is the specified kit, etc., so as to quickly determine whether the operation can be started and improve the efficiency.

[0117] Among them, the controller can obtain all images including the first target image, the second target image, and the third target image. Therefore, the controller can determine the working state of the extraction device in real time to ensure the normal operation of the device.

[0118] In one embodiment, the extraction system further includes:

[0119] A mobile terminal, which is communicatively connected to the camera in the extraction device and is used to obtain corresponding target images through the camera to determine the working condition of the extraction device; preferably, the mobile terminal includes a notebook and a mobile phone.

[0120] To improve the user experience and facilitate monitoring, the working condition of the extraction device can be monitored through a mobile device to ensure the normal operation of the extraction device.

[0121] Preferably, the extraction system further includes:

[0122] A cloud server, which is communicatively connected to the camera and is used to obtain and store the target images obtained by the camera.

[0123] Although the mobile device can monitor the running state of the extraction device in real time, users generally do not continuously monitor the extraction device. Therefore, all target images obtained by the camera can be stored in the cloud server for subsequent users to check the working condition of the extraction device.

[0124] In one embodiment, the mobile terminal is communicatively connected to the cloud server and is used to obtain the target images obtained by the camera stored in the cloud server to determine the working condition of the extraction device.

[0125] After the mobile terminal is communicatively connected to the cloud server, the target images stored on the cloud server can be checked at any time through the mobile terminal, so as to determine whether there is an abnormality in the extraction device. Therefore, in this embodiment, the target images can be statically checked to determine whether the extraction device is abnormal, and the target images can also be dynamically checked to determine whether the extraction device is abnormal, so as to ensure the normal operation of the extraction device.

[0126] The specific descriptions of the extraction device, reagent kit, and label involved in the extraction system have been elaborated in the above content of this embodiment. For details, reference can be made to this embodiment, and this embodiment will not be further described here.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
