[0021] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] The terms "first," "second," and the like in this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present application first provides a sample analyzer, in which the project detection reagent cards supported by the instrument can be installed into a custom reagent card box and put into the sample analyzer for use, so as to meet the usage scenarios of different sample quantities of the client. The user group with a small average daily sample volume can choose to use a single reagent card with a custom card box, and use as much as needed, or install a corresponding amount of reagent cards in the custom card box according to actual needs. In this way, it can effectively avoid the situation where the reagent card is opened for too long, resulting in the reagent card being unused for too long, and then becoming invalid. It can also improve the reuse rate of the reagent card box and reduce manufacturing costs.

[0025] See also Figure 1 As shown, Figure 1It is a schematic diagram of the framework of an embodiment of a sample analyzer provided by this application. Specifically, the sample analyzer 10 includes: a fixed seat 11, a reading unit 12, an analysis unit 13, and a control unit 14.

[0026] Among them, the fixed seat 11 is used to fix the reagent cartridge 20. Specifically, the fixed seat 11 is formed with at least one fixing bin (not shown in the figure), and the reagent cartridge 20 is fixed in the fixing bin. The fixed seat 11 can form multiple fixing bins, and each fixing bin can be used to fix reagent cartridges 20 of the same detection type or different detection types.

[0027] The reagent cartridge 20 is used to carry reagent cards for sample testing. A reagent cartridge 20 can carry multiple reagent cards or one reagent card. The reagent card can include at least one of a fluorescence immunochromatographic test card, a colloidal gold immunochromatographic test card, a boric acid affinity test card, and a chromatographic test card, for chromatographic detection of immune proteins in the sample. Optionally, the sample test card can also include: a PCT (procalcitonin) reagent card, an IL-6 (interleukin 6) reagent card, etc.

[0028] Please continue to refer to Figure 2 as shown Figure 2 is Figure 1 a schematic structural diagram of an embodiment of the reagent cartridge in the sample analyzer shown. Specifically, the reagent cartridge 20 includes a cartridge body 21 and a first storage medium 22. The first storage medium 22 is provided on the cartridge body 21. Among them, the first storage medium 22 can be an RF (Radio Frequency) card, a two-dimensional code identifier, or a barcode identifier, etc. That is, each reagent cartridge 20 is configured with a first storage medium 22, and the first storage medium 22 can be regarded as the identity identifier of the reagent cartridge 20. The first storage medium 22 is used to store the detection item information of the reagent cards on the reagent cartridge 20. The detection item information corresponding to this reagent cartridge 20 can include custom detection item information and the determined detection items corresponding to this reagent cartridge 20. The custom detection item information here indicates that this reagent cartridge 20 is a custom cartridge without information on determined detection items. Each time a custom reagent cartridge is loaded into the sample analyzer, the determined detection items corresponding to this custom reagent cartridge can be redefined according to the actual situation. The determined detection items refer to the determined detection items corresponding to the reagent cartridge 20. For example, the determined detection items include CRP (C-reactive protein) detection. Specifically, the determined detection items can be the specific detection items fixed by the reagent cartridge with fixed detection items itself, or the specific detection items further determined after determining that the reagent cartridge 20 is a custom reagent cartridge. The analysis unit 13 can detect the reagent cards on the corresponding reagent cartridge 20 based on the determined detection items.

[0029] Furthermore, the categories of the reagent cartridges 20 include reagent cartridges 20 for fixed detection items and custom reagent cartridges 20. The reagent cartridges 20 for fixed detection items correspond to determined detection items, that is, the detection items of the reagent cards on the reagent cartridges 20 for fixed detection items are clear and fixed. For example, the determined detection item corresponding to the reagent cartridges 20 for fixed detection items is quantitative detection of procalcitonin. Therefore, the first storage medium 22 of the reagent cartridges 20 for fixed detection items, which is sold in units of one box, stores the determined detection items corresponding to the reagent cartridges 20. Specifically, the detection item information stored in the first storage medium 22 of the reagent cartridges 20 for fixed detection items may include at least one of the reagent cartridge category, the detection item name for the determined detection item, the item unit, the calibration curve, the test scheme, the number of peaks, and the peak extraction algorithm.

[0030] The test items corresponding to the custom reagent cartridge 20 are not fixed. The reagent cards corresponding to the test items that need to be tested can be loaded into the custom reagent cartridge according to demand, and then the custom reagent cartridge carrying the reagent cards can be loaded onto the sample analyzer. The reagent cards on the custom reagent cartridge 20 can be reagent cards for a single person, and the reagent cards for the single person are independently packaged. Users can set the corresponding number of reagent cards according to the detection requirements of the sample. For example, if the detection of a certain sample requires 2 reagent cards, 2 reagent cards can be placed on the reagent cartridge 20. In this way, users can unpack the reagent cards on demand. Compared with the prior art, a reagent cartridge is equipped with multiple reagent cards, and the reagent cartridge is unpacked and placed in the sample analyzer for use. If the reagent cards in the reagent cartridge are not used in time, the reagent cards will become invalid, which will then lead to the waste of reagent cards. The present application can place reagent cards on demand to reduce waste. The test item information stored in the first storage medium 22 in the custom reagent cartridge 20 is the custom test item information. The custom test item information indicates that the reagent cartridge 20 does not have fixed test items, and the corresponding confirmed test items for each test need to be further input. Before the sample analyzer 10 detects the reagent card of the custom reagent cartridge 20, it needs to be used in conjunction with the second storage medium (not shown). After the control unit 14 determines that the reagent cartridge 20 is a custom reagent cartridge 20 through the first storage medium 22, the sample analyzer 10 can obtain the confirmed test items corresponding to the custom reagent cartridge 20 through the second storage medium.

[0031] The reading unit 12 is used to read the content stored in the first storage medium 22 and the second storage medium. For example, when the first storage medium 22 and the second storage medium are RF cards, the reading unit 12 can be an RF card reader. The location of the reading unit 12 can be determined based on the scanning position of the first storage medium 22 and the second storage medium.

[0032] The analysis unit 13 is used to detect and analyze the reagent card added with the sample. The analysis unit 13 can detect the reagent card according to the determined detection items corresponding to the reagent card cartridge 20 to obtain the detection result of the sample.

[0033] The control unit 14 is connected to the reading unit 12 and the analysis unit 13 to perform sample detection and analysis.

[0034] Based on the sample analyzer 10 of any of the above embodiments, the present application further provides a control method for a sample analyzer. Specifically, as Figure 3 shown, the control method includes:

[0035] S11: Receive the detection item information corresponding to the reagent card cartridge read by the reading unit from the first storage medium after the reagent card cartridge is placed in the fixed bin. Among them, the detection item information includes: custom detection item information or the determined detection items corresponding to the reagent card cartridge.

[0036] The sample analyzer 10 includes a fixed seat 11, and the fixed seat 11 forms a plurality of fixed bins. The reading unit 12 may include a plurality of sub-reading units. One sub-reading unit may be correspondingly set for each fixed bin. After the reagent card cartridge 20 is placed in the fixed bin, the sub-reading unit corresponding to the fixed bin can read the first storage medium 22 on the reagent card cartridge 20.

[0037] For example, when the first storage medium 22 is an RF card, an RF card reader and a micro switch may be provided in each fixed bin. When the control unit 14 detects that the state of the micro switch has changed, the RF card reader reads the RF card on the reagent card cartridge 20 to obtain the detection item information corresponding to the reagent card cartridge 20.

[0038] The control unit 14 receives the detection item information corresponding to the reagent card cartridge from the reading unit 12. Through the detection item information of the reagent card cartridge 20, it can be confirmed whether the type of the reagent card cartridge 20 is a custom reagent card cartridge. When the detection item information is custom detection item information, the reagent card cartridge 20 is a custom reagent card cartridge 20. When the detection item information includes determined detection items, the reagent card cartridge is a reagent card cartridge 20 with fixed detection items.

[0039] S12: After confirming that the detection item information corresponding to the reagent card cartridge is custom detection item information, receive the determined detection items corresponding to the reagent card cartridge read by the reading unit from the second storage medium.

[0040] After the control unit 14 obtains the detection item information corresponding to the reagent cartridge 20, when it is confirmed that the detection item information is custom detection item information, the reagent cartridge 20 can be considered as a custom reagent cartridge 20. This custom reagent cartridge 20 does not have fixed detection items and cannot be used directly. Therefore, the reading unit 12 can read the second storage medium again to obtain the determined detection items corresponding to the custom reagent cartridge 20 from the second storage medium.

[0041] Optionally, after the control unit 14 confirms that the detection item information of the reagent cartridge 20 is custom detection item information, it can generate and send a reminder message to remind the user to manually swipe the card at the reading unit 12 so that the reading unit 12 reads the second storage medium. For example, the reading unit 12 includes a first sub-reading unit and a second sub-reading unit. The first sub-reading unit is disposed in the fixed bin, and the second sub-reading unit is disposed outside the fixed seat 11, such as on the outside of the housing of the sample analyzer 10. The first sub-reading unit is used to read the first storage medium 22 on the reagent cartridge 20 after the reagent cartridge 20 is placed in the fixed bin. When it is confirmed that the reagent cartridge 20 is a custom reagent cartridge 20, a reminder is generated and sent to remind the user to manually swipe the card at the second sub-reading unit. The user can hold the second storage medium to the second sub-reading unit, and the second sub-reading unit reads the second storage medium to obtain the determined detection items corresponding to the custom reagent cartridge 20 from the second storage medium.

[0042] Optionally, the second storage medium can also be directly disposed on the reagent card. After the reading unit 12 obtains the detection item information of the reagent cartridge 20 from the first storage medium 22, when the control unit 14 determines that the reagent cartridge 20 is a custom reagent cartridge 20 based on the detection item information, the reading unit 12 directly reads the second storage medium on the reagent card to obtain the determined detection items corresponding to the reagent cartridge 20 from the second storage medium. In this way, the steps of manual operation can be reduced.

[0043] Furthermore, the sample analyzer 10 can further include a display unit (not shown in the figure). The control unit 14 is further configured to control the display unit to display a setting interface for the user to set the quantity information of the reagent cards placed in the custom reagent cartridge 20 after the reading unit 12 reads the determined detection items corresponding to the custom reagent cartridge 20 from the second storage medium. In this way, the sample analyzer 10 can obtain the quantity of the reagent cards on the custom reagent cartridge 20, providing a reference for sample detection.

[0044] When the detection item information obtained by the control unit 14 through the first storage medium 22 is a determined detection item, it is confirmed that the reagent cartridge 20 is a reagent cartridge for fixed detection items. The control unit 14 directly obtains the determined detection item corresponding to the reagent cartridge 20 from the detection item information, and there is no need to write it into the second storage medium again.

[0045] S13: When a detection analysis requirement corresponding to the determined detection item is received, the control analysis unit performs detection analysis on the reagent cards on the corresponding reagent cartridge based on the determined detection item.

[0046] After the control unit 14 obtains the determined detection item corresponding to the reagent cartridge 20, when a detection analysis requirement corresponding to the determined detection item is received, the control analysis unit 13 performs detection on the reagent cards on the corresponding reagent cartridge 20 based on the determined detection item.

[0047] Specifically, after the control unit 14 reads the determined detection item corresponding to the reagent cartridge 20, it can store the information of the determined detection item in the file of the fixed bin corresponding to the reagent cartridge 20. Whichever fixed bin's reagent card the analysis unit 13 tests, it calls the file of that fixed bin position to obtain the corresponding determined detection item, and the analysis unit 13 performs detection analysis on the reagent card according to the determined detection item.

[0048] The reagent cartridge 20 can be directly used in different fixed bin positions, and the corresponding determined detection item in the fixed bin is called when using the reagent card.

[0049] In the sample analyzer 10 of the above embodiment, the sample analyzer 10 can use the custom reagent cartridge 20, which can meet the usage scenarios of different sample volumes. Users can use single-use reagent cards and place the reagent cards on the custom reagent cartridge 20 as needed. In this way, it can effectively avoid the situation where the reagent card becomes invalid due to being unused for too long after opening, and by using the custom reagent cartridge 20, the reuse rate of the reagent cartridge 20 can be increased and the cost can be reduced.

[0050] The custom reagent cartridge 20 can support the use of one item or multiple items each time during detection. For example, when the second storage medium is an RF card, the custom reagent cartridge 20 only supports one item each time during detection. If the second storage medium is set on the reagent card, each custom reagent cartridge 20 can support the use of multiple different items each time, and it can support switching to other determined detection items for use after re-reading the second storage medium. In this way, the reagent cartridge 20 can be reused and the waste of materials can be reduced.

[0051] Optionally, the control unit 14 can also be used to obtain the theoretical quantity of the corresponding reagent cards required for a predetermined test item and the actual quantity of the corresponding reagent cards in the fixed seat 11. When it is confirmed that the actual quantity of the corresponding reagent cards is less than the theoretical quantity, based on the difference, a reminder is given that the remaining quantity of the corresponding reagent cards is insufficient, enabling the user to replace the new reagent card cartridge 20 in a timely manner. That is, when the actual quantity of the corresponding reagent cards does not meet the current test requirements, a prompt message can be popped up according to the difference between the two to remind the user to replace the new reagent card cartridge 20. In this way, the reliability of the sample analyzer 10 for sample testing can be improved.

[0052] For example, according to the quantity of reagent cards for test item A required for the item to be tested and the quantity of reagent cards for test item A already existing in all the fixed bins of the instrument, it is determined whether the quantity of reagent cards for test item A already existing in the fixed bin meets the current test requirements. If not, according to the difference between the two, a prompt message is popped up to remind the user to replace the new reagent card cartridge 20, and the quantity information of the difference can be displayed. In this way, the quantity of reagent cards can be intelligently monitored, and the reliability of the operation of the sample analyzer 10 can be improved.

[0053] Optionally, the control unit 14 is also used to use the reagent cards according to a specific order. For example, the priority of using the reagent cards from high to low is as follows: the expiration date of the reagent cards, the remaining quantity of various reagent cards, and the sorting of the fixed bins. That is, the reagent cards about to expire are used first. Under the same conditions, the reagent cards with the least remaining quantity can be used first. If the above conditions are the same, they can be used according to the order of the positions of the fixed bins. By reasonably arranging the usage priority of the reagent cards, material waste can be reduced, and the detection efficiency of the sample analyzer can be improved.

[0054] The method for obtaining the expiration date of the reagent cards is as follows: when the reagent card cartridge 20 for a fixed test item is placed in the fixed bin, the reading unit 12 reads the first storage medium 22 to identify the expiration date of the reagent cards. When the single - person reagent cards in the custom reagent card cartridge 20 are scanned and identified by the reading unit 12 when reading the second storage medium, the expiration date of the reagent cards is recorded.

[0055] Optionally, when the control unit 14 confirms that the reagent card corresponding to the first test item in the fixed bin is used up, a reminder message is sent to remind that the reagent card corresponding to the first test item is used up, so that the user can replenish the corresponding reagent card in time based on this reminder message. When the control unit 14 also obtains the detection requirement of the analysis unit 13 for the second test item, the control unit 14 controls the analysis unit 13 to stop the detection of the first test item and controls the analysis unit 13 to detect the reagent card corresponding to the second test item for the second test item. For example, when all the reagent cards of a certain test item (such as test item A) in all the fixed bins are used up, a reminder message pops up to remind the user to replace them; when the control unit 14 also detects the detection requirement of another test item (such as test item B), the reminder message can be manually cancelled, the detection of test item A is paused, and the detection of test item B can still be performed. After the control unit 14 confirms that a new reagent card for test item A is replaced, the reminder message is automatically cancelled or can be manually cancelled.

[0056] In the sample analyzer 10 of the above embodiment, a custom reagent card cassette 20 can be used. In the custom reagent card cassette 20, reagent cards for single use can be set as needed to meet the usage scenarios of different sample volumes. The situation where the reagent card becomes invalid due to being unsealed for too long without use is avoided. Moreover, since the custom reagent card cassette 20 does not have fixed test items, the custom reagent card cassette 20 can be reused, reducing the manufacturing cost. In addition, the sample analyzer 10 can track the quantity of reagent cards and send a reminder in time when the quantity is insufficient, with a high degree of intelligence, improving the reliability of the sample analyzer 10 for sample detection.

[0057] This application also provides a reagent card cassette, and this reagent card cassette is a custom reagent card cassette. Please refer to Figure 2 As shown, the custom reagent card cassette 20 includes: a cassette body 21 and a first storage medium 22. Among them, the cassette body 21 is used to fix the reagent card, and at least one reagent card can be fixed on the cassette body 21.

[0058] The first storage medium 22 is provided on the cassette body 21, and custom test item information is stored in the first storage medium 22, which is used to indicate that the type of the reagent card cassette 20 is a custom reagent card cassette 20. For example, the first storage medium 22 can be an RF card, and the RF card can be pasted on the cassette body 21, and the custom test item information is stored in the RF card. In other embodiments, the first storage medium 22 can also be: a two-dimensional code or a bar code, etc.

[0059] This reagent card cassette 20 does not have fixed test items, and its specific test items can be set during each test. Each reagent card cassette 20 is correspondingly configured with a first storage medium 22, which is used to identify its identity as a custom reagent card cassette 20.

[0060] The reagent cards used in the reagent card cassette 20 can be single-person reagent cards. Users can install as many reagent cards on the reagent card cassette 20 as needed according to their requirements. Moreover, after the reagent cards are used up, after the customized reagent card cassette 20 is withdrawn from the sample analyzer, users can also replace the reagent cards so that the reagent card cassette 20 can be reused, saving costs.
