The placing layer 15 is provided with five layers and is used for placing various reagent bottles. In the reagent cabinet 1, a first layer containing layer 15a, a second layer containing layer 15b, a third layer containing layer 15c, a fourth layer containing layer 15d and a fifth layer containing layer 15e are arranged from top to bottom in sequence. Wherein, each layer of the placing layer 15 has a placing plate on which the reagent bottles are placed (the placing plate of the fifth layer of the placing layer 15e is the bottom plate of the reagent cabinet 1).

FIG. 3 is a schematic view showing the arrangement state of a reagent bottle in the embodiment of the present invention.

Taking the first-layer placing layer 15a as an example, as shown in fig. 3, the reagent bottles 151 can be freely placed on the placing plate 153. A reagent label 152 is provided on the cap of the reagent bottle 151.

Fig. 5 is a content stored in the counter number layer number storage unit in the embodiment of the present invention.

In this embodiment, in order to distinguish the reagent cabinets 1, each reagent cabinet 1 in the laboratory is provided with a cabinet number for identification. Meanwhile, in each reagent cabinet 1, the respective placing layers 15 are also provided with corresponding layer numbers in sequence, for example, the placing layer 15 of the first layer has a layer number of 1. As shown in fig. 5, the rack number-layer number storage unit 192 stores a rack number 1921 of the current reagent rack 1, a layer number 1922 of each rack layer 15, and a determination unit number 1923 of the determination unit 16 corresponding one-to-one to each layer number 1922. In practical applications, the cabinet number is a chip identification code of the main control chip 19, and the identification unit number is a machine code of each identification unit.

When a laboratory technician takes out or returns a reagent and closes the cabinet door 12, once the sensing part 14 senses that the cabinet door 12 is closed, the main control chip 19 controls the locking part 13 to lock the cabinet door 12, and controls the judging parts 16 to shoot images of the placing layers and judge reagent judging information of all reagent bottles 15 in the corresponding placing layers, at this time, the main control chip 19 corresponds the judged reagent judging information with the layer number corresponding to the judging part 16 making the judgment, and further controls the reagent cabinet communication part 191 to send the judged reagent judging information, the corresponding layer number and the current cabinet number of the reagent cabinet 1 to the management server 2 for processing.

The laboratory technician terminal 3 is a personal computer of a laboratory technician, and is used for the laboratory technician to input the name of the experiment and inquire about the corresponding required reagent bottle and the position of the reagent bottle. In this embodiment, before the experimenter uses the experimenter terminal 3, the experimenter needs to log in through respective identification information in advance, so that the experimenter terminal 3 stores the identification information of the experimenter, and the experimenter terminal 3 can send the identification information of the current experimenter to the management server 2 when communicating with the management server 2.

FIG. 6 is a flow chart of reagent extraction steps of the intelligent management method for experimental reagents in the embodiment of the present invention.

As shown in fig. 6, the intelligent management method for experimental reagents in this embodiment is implemented based on the system 100 including the reagent cabinet 1, the management server 2, the laboratory technician terminal 3, and the communication network 4, and is used for managing the reagents based on reagent labels, and specifically includes the following reagent extraction steps:

step S1-1, storing the reagent discrimination information, the reagent names and the corresponding reagent position information corresponding to all the reagent bottles as the reagent related information in advance, wherein the reagent position information includes the cabinet number of the reagent cabinet where the reagent bottle is located and the layer number of the placing layer, and then proceeding to step S1-2.

In step S1-1 of the present embodiment, the reagent-related information is stored in a management server 2 in a setup laboratory, the management server 2 having a reagent-related information storage module for storing the reagent-related information.

FIG. 7 shows contents stored in the reagent-related information storage unit according to the first embodiment of the present invention.

As shown in fig. 7, the reagent-related information storage unit 21 stores the following information: reagent discrimination information 211, and corresponding reagent name 212 and reagent position information 213. Specifically, the method comprises the following steps:

the reagent discrimination information 211 is the number information of the reagent bottles 151, and the reagent labels on the respective reagent bottles 151 contain the reagent discrimination information indicating the respective different numbers.

The reagent name 212 is a reagent name of the reagent contained in the reagent bottle 151.

The reagent position information 213 includes the cabinet number of the reagent cabinet 1 and the layer number of the placement layer 15.

As can be seen from the above figure, the reagent position information corresponding to the different reagent discrimination information 211 may be the same, and if the reagent position information corresponding to the reagent discrimination information P1 and P2 are the same, it indicates that two reagent bottles containing different reagents are stored in the same storage layer 15 of the same reagent kit 1.

The reagent identification information P2, P3, and P4 correspond to the same reagent name, but the corresponding reagent position information is different, indicating that three reagent bottles containing the same reagent are placed at different positions (the reagent bottles corresponding to P2 and P3 are placed on different placement levels 15 of the same reagent box 1, and the reagent bottles corresponding to P4 are placed in other reagent boxes 1).

The reagent position information corresponding to the reagent discrimination information P7 is a null value, indicating that the reagent bottle corresponding to the reagent discrimination information is in a state of being extracted by the laboratory technician and is not in the reagent tank 1.

In step S1-2, when the laboratory technician selects one reagent kit 1 and prepares to extract the reagent, the identification unit 17 (i.e., the identification module) allows the laboratory technician to identify the identification information of the laboratory technician by swiping a card, and the reagent kit communication unit 191 transmits the identification information to the management server 2, and the process proceeds to step S1-3.

Step S1-3, using the identity determination module of the management server 2 to determine the identity of the experimenter according to the received identification information and determine whether to let the locking portion 13 (i.e., the locking module) unlock the cabinet door 12 of the reagent cabinet 1, so that the experimenter opens the cabinet door 12 to extract the reagent and closes the cabinet door 12 after extraction is completed, and then step S1-4 is performed.

In this embodiment, the identity determination module is a computer program provided in the management server 2, and the management server 2 stores identification information of all the laboratory technicians in the laboratory. When the determination is made based on the identification information in step S1-3, the identity determination module retrieves all the identification information stored in the management server 2 based on the identification information, and if the matching identification information is retrieved, the management server 2 sends a door opening permission signal to the reagent cabinet 1, and at this time, the locking portion 13 unlocks the cabinet door 12, so that the laboratory technician opens the cabinet door 12 and extracts the reagent.

In step S1-4, after the door is closed by the laboratory technician as sensed by the sensing part 14 (i.e., sensing module) provided in the reagent kit 1, the door 12 is locked by the locking part 13 (i.e., locking module), and then the process proceeds to step S1-5.

In step S1-5, the discrimination unit 16 (i.e., the discrimination module) provided in the reagent cassette 1 discriminates the reagent labels provided to all the reagent bottles 151 on each of the rack layers 15 in the reagent cassette to obtain a plurality of pieces of reagent discrimination information corresponding to each rack layer, and the process proceeds to step S1-6.

In this embodiment, the step S1-5 specifically includes sub-steps S1-5-1 and S1-5-2:

step S1-5-1, each image capturing unit 161 captures a respective placement layer 15 to obtain a placement layer image of each placement layer 15 in the current reagent cabinet 1;

in step S1-5-2, the two-dimensional code discrimination section 162 discriminates the image of the rack layer captured in step S1-5-1, thereby discriminating the reagent discrimination information of all the reagent bottles 151 in each rack layer 15, and the process proceeds to step S1-6.

And step S1-6, updating the corresponding reagent position information in the reagent related information according to the reagent identification information, the layer number corresponding to the placing layer 15 and the cabinet number corresponding to the reagent cabinet 1 which are identified in the step S1-5, and then entering an ending state.

In this embodiment, when the management server 2 receives the reagent identification information, the layer number, and the cabinet number sent by the reagent cabinet 1, the step S1-6 is executed by the comparison determination module and the related information update module of the management server 2, and specifically, the step S1-6 includes the following sub-steps:

and step S1-6-1, comparing all the received reagent discrimination information with the same cabinet number and the same layer number in the reagent related information by adopting a comparison judgment module according to the cabinet number and the layer number so as to judge the missing reagent discrimination information.

In step S1-6-1 of the present embodiment, when the two types of reagent discrimination information to be compared have the same cabinet number and layer number when the comparison of the reagent discrimination information is performed, if the plurality of reagent discrimination information among the reagent-related information includes reagent discrimination information that is not included in the reagent discrimination information determined in step S1-7 (that is, includes missing reagent discrimination information), it indicates that the missing reagent discrimination information is a reagent taken out of the corresponding reagent cabinet 1 accommodating layer 15.

In step S1-6-2, if it is determined in step S1-6-1 that there is missing reagent discrimination information, the relevant information update module of the management server 2 updates the corresponding reagent position information in the reagent relevant information according to the missing reagent discrimination information.

Specifically, the related information updating module deletes the corresponding reagent position information in the reagent related information according to the missing reagent identification information (at this time, the reagent position information corresponding to the reagent identification information is empty, which indicates that the reagent has been removed).

FIG. 8 is a flowchart of reagent requesting steps of an intelligent management method for experimental reagents according to an embodiment of the present invention.

As shown in fig. 8, the intelligent management method for experimental reagents further includes the following reagent request steps:

step A1-1, displaying a reagent request screen for the laboratory technician to input the name of the reagent to be requested as the name of the required reagent, and then proceeding to step A1-2.

In the present embodiment, a reagent request screen on which a text box for allowing the laboratory technician to input characters is displayed on a display device (for example, a display) of the laboratory technician terminal 3 held by the laboratory technician. After the experimenter enters a character in the text box through an input device (e.g., a keyboard) of the experimenter terminal 3 and confirms, the experimenter terminal 3 sends the character to the management server 2 as a name of the required reagent, and then the management server 2 performs the retrieval of step S1-3.

Step A1-2, the retrieval obtaining module is adopted to retrieve the relevant information of the reagent stored in step S1-1 according to the required reagent name input in step A1-1 so as to obtain the corresponding reagent position information, and then the step A1-3 is proceeded.

In this embodiment, when receiving the required reagent name input in step S1-2, the management server retrieves consistent reagent information from the stored reagent-related information according to the required reagent name through the retrieval obtaining module, and further obtains all corresponding reagent discrimination information and reagent position information.

Step A1-3, sending the required reagent name input in step A1-1 and the retrieved reagent position information retrieved in step A1-2 as extraction information to a laboratory technician, making the laboratory technician go to the corresponding reagent cabinet 1 according to the extraction information, and then entering step S1-2 when the laboratory technician operates the reagent cabinet 1 to make the reagent cabinet 1 identify the identification information.

Fig. 9 shows the content of the extracted information according to the first embodiment of the present invention.

Taking the input required reagent name SJ2 as an example, as shown in fig. 9, the extraction information 221 includes the reagent name 2211 and the corresponding reagent position information 2212.

Examples effects and effects

According to the intelligent management method for the experimental reagent provided by the embodiment, because the reagent discrimination information and the reagent position information of all the reagents in the laboratory are stored as the reagent related information, the reagent related information can be retrieved and the corresponding reagent position information can be obtained after the required reagent name input by the experimenter, so that the experimenter can directly inquire the required reagent and the position of the reagent. Simultaneously, because take out reagent and close the cabinet door of reagent cabinet at the laboratory technician after, can also distinguish all reagent bottles on each placing layer in the reagent cabinet, and relevant information is updated to the reagent through the reagent discrimination information that distinguishes and corresponding layer number of placing and reagent cabinet number of placing, consequently realized the control to reagent bottle movement in the laboratory, thereby accurately accomplish the arrangement of reagent position when the reagent bottle is placed in the reagent cabinet, further make the laboratory technician can obtain the positional information of required reagent effectively when requesting. The intelligent management method for the experimental reagent realizes effective monitoring of the reagent position in the laboratory, so that a laboratory technician can simply and definitely find the position of the required reagent, and the laboratory technician can conveniently take the reagent, and the limited energy of the laboratory technician is not wasted.

In addition, in the first embodiment, since the reagent-related information can be determined according to the cabinet number, the layer number, and the determined reagent determination information, it can be determined whether or not a reagent bottle in the reagent cabinet has been extracted by a laboratory technician, accurately managing the status of each reagent bottle in the reagent cabinet, and preferably accurately modifying the reagent position information of the reagent bottle, according to whether or not the reagent determination information is missing in the front or in the back.

In addition, in the first embodiment, when returning the reagent, the laboratory technician can select one reagent cabinet at will and place the returned reagent on any one of the placement layers without worrying about confusion of reagent management, so that the laboratory technician puts more energy originally used for managing the reagent into a professional experiment, and the work efficiency of the laboratory technician is improved.

In the first embodiment, a reagent label based on a two-dimensional code is used to identify the reagent discrimination information of each reagent bottle, a camera provided in the reagent cabinet is used to photograph the two-dimensional code, and the two-dimensional code discrimination section discriminates the two-dimensional code in the image to obtain the reagent discrimination information of each reagent bottle. Through such a mode, the laboratory can conveniently and accomplish the preparation of two-dimensional code label with low costs, for example through the mode of printing the two-dimensional code on the paper to the paper that will print the two-dimensional code is tailor and is pasted on the reagent bottle as the two-dimensional code label. However, such a method has a certain drawback that each two-dimensional code label must be provided with a position where a bottle cap of a reagent bottle or the like is easily photographed, and the two-dimensional code label is easily broken.

In the second embodiment, since the reagent position information and the identification information are stored as the request record information, when the laboratory technician extracts the reagent, it can be determined whether the identification information of the laboratory technician determines that the identification information and the cabinet number of the reagent cabinet where the laboratory technician is located match the request record information, and the locking module unlocks the reagent cabinet only when it is determined that the identification information and the cabinet number match. Therefore, the problem that the reagent is used without permission by a laboratory technician can be further avoided, the problem that the corresponding reagent cannot be found due to mistaken identification of the reagent cabinet when the reagent is extracted by the laboratory technician can be avoided, and the reagent taking management in a laboratory can be better realized.

In the second embodiment, because the reagent discrimination information and the identification information are stored as the extraction record information, when the laboratory staff returns the reagent, whether the identification information of the laboratory staff is matched with the extraction record information or not can be judged, and the locking is released by the locking module only when the matching is judged, so that when the laboratory staff needs to return the reagent, the reagent cabinet can be opened by the identification information of the laboratory staff, any reagent cabinet can be opened by the laboratory staff and the reagent is returned, the safety requirement in a laboratory and the convenience requirement of the reagent are both considered, and the energy consumed by the laboratory staff when the reagent is returned is saved.

< modification example >

In this modification, the same reference numerals are given to the components having the same configurations as those in the first embodiment, and the description thereof will be omitted.

The present modification provides an experimental reagent management system using an RFID tag as a reagent tag. The difference from the first embodiment lies in the reagent label on the reagent bottle and the discrimination section in each layer of the mounting layer, and the specific differences are as follows:

in this modification, the reagent label is an RFID label including reagent identification information, and can be attached to any position of the reagent bottle 151, such as a bottle cap, a bottle body, or a bottle bottom.

The determination unit is a reader capable of identifying RFID and is disposed at any position in the reagent tank 1 where normal sensing can be performed, for example, at the center of the top of each placement layer 15. In this case, the discrimination section can directly recognize the reagent discrimination information of all the reagent bottles 151 in each rack layer 15 when performing the discrimination.

When the laboratory technician takes out or returns the reagent and closes the cabinet door 12, once the sensing part 14 senses that the cabinet door 12 is closed, the main control chip 19 controls the locking part 13 to lock the cabinet door 12, controls the discriminating part 16 to discriminate all the reagent discriminating information corresponding to each placing layer 15, and further controls the reagent cabinet communication part 191 to send the discriminated reagent discriminating information and the corresponding layer number and cabinet number to the management server 2 for processing.

In this modification, the reagent identification information for identifying each reagent bottle by the RFID-based reagent label is used, and the RFID identifier provided in the reagent tank identifies these reagent labels. In this way, although the manufacturing cost of the RFID tag is increased, the RFID tag can be easily installed at each position of the reagent bottle without affecting the normal identification of the reagent identification information, and the RFID tag is less likely to be damaged.

The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.

For example, in the above embodiment, the reagents corresponding to the reagent discrimination information included in the extracted information are all extracted by the experimenter, however, in other embodiments of the present invention, the experimenter may also obtain only the reagents corresponding to part of the extracted information. At this time, the extracted information display screen further has a reagent selecting portion. Specifically, when the same reagent name in the relevant information of the reagent has a plurality of corresponding reagent discrimination information, the extraction information includes a plurality of reagent discrimination information, and after the extraction information is sent to the laboratory technician terminal, the extraction information display screen displays each reagent name and corresponding reagent position information in the extraction information at the reagent selecting part, so that the laboratory technician selects one or more reagents to view in detail, and at the moment, the extraction information display screen displays the reagent position information corresponding to the selection of the laboratory technician so that the laboratory technician can extract the reagent. Therefore, the intelligent management method for the experimental reagent can enable an experimenter to selectively extract the reagent.

For another example, in the above embodiment, the identity determination module is a computer program provided in the management server, and the identity determination of the experimenter is completed based on the identification information of all the experimenters stored in the management server. However, in other embodiments of the present invention, the identification information of all the experimenters may also be stored in the main control chip of the reagent cabinet, and after the identification module identifies the identification information of the experimenters, the main control chip executes the work corresponding to the identity retrieval module to determine whether to unlock the cabinet door to allow the experimenters to extract or return the reagent. In addition, when the identity of the experimenter needs to be determined according to the request record and the extraction record, the request record and the extraction record can be periodically updated and stored in the main control chip by the management server, so that the main control chip can complete the identity determination of the experimenter according to the records. In such a case, each reagent cabinet can independently determine the identity of the laboratory worker.

For example, in the above-described embodiment, one image pickup unit is provided in the center of the interlayer sheet above each placement layer. However, if the height of the placing layer is low, and the shooting range of the shooting unit is insufficient, in order to ensure that all the two-dimensional codes in the placing layer can be completely shot, a plurality of shooting units can be arranged on each interlayer plate above the placing layer, and the whole placing layer image of the placing layer can be obtained by splicing.

For example, in the above-described embodiment, the identification information is door card information in a door opening card held by an experimenter, and the identification portion is a door card reading device. Alternatively, the identification information may be a password, two-dimensional code information corresponding to the identity of the experimenter, fingerprint information of the experimenter, or face information, and an identity recognition portion corresponding to the identification information, that is, a password input device, a two-dimensional code scanning device, a fingerprint recognition device, or a face recognition device, is provided in a matching manner. Through such mode, also can realize authentication's effect, the laboratory technician can operate identification portion through corresponding mode, lets identification portion discern this laboratory technician's identification information through operations such as input password, scanning two-dimensional code, verification fingerprint, shooting people's face promptly.

For example, in the above-described embodiment, the reagent-related information storage unit stores only the reagent name and the reagent position information. In practical applications, the reagent-related information storage unit may also store other reagent-related information, such as reagent specifications and instructions.

In the above embodiment, the warning portion is a warning light disposed on the front surface of the cabinet door. In other embodiments of the present invention, the warning portion may be an audible and visual alarm or other device with a prompting effect, and is disposed at a position on the reagent cabinet where the alarm is easily observed or a position where the alarm is easily emitted.
