[0002] In the field of medical testing, test strips are a commonly used rapid testing method. Currently, testing instruments require pre-entry of test strip information, such as production date and batch number, before use. This not only increases the workload of medical staff but also easily leads to data entry errors due to human error. Furthermore, since test strips are usually sold in boxes, each box containing an information card, medical staff often enter all the information from all the cards into the system at once. This practice can easily cause a mismatch between the test strip information and the actual test strips used, affecting the accuracy of the test results. Summary of the Invention

[0095] The present application will be further described below with reference to the accompanying drawings and specific embodiments. The described embodiments should not be considered as limitations on the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0096] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0097] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0098] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatuses.

[0099] It should be understood that in this application, "at least one (item)" means one or more, and "more than" means two or more. "And / or" is used to describe the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0100] It should be understood that in the description of the embodiments of this application, "multiple" means two or more, "greater than", "less than", "exceeding" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself.

[0101] In existing testing instruments, test strip information, such as production date and batch number, often needs to be pre-entered before use. This not only increases the workload of medical staff but also easily leads to data entry errors due to human error. Furthermore, since test strips are usually sold in boxes, each box containing an information card, medical staff often enter all the information card content into the system at once. This practice can easily cause a mismatch between the test strip information and the actual test strips used, affecting the accuracy of the test results.

[0102] Furthermore, existing testing instruments suffer from another problem: since test strips are a crucial consumable, using non-original test strips can not only affect the accuracy of test results but may also damage the instrument. Currently available anti-counterfeiting technologies often require additional identification devices, which not only increases equipment costs but also makes the system structure more complex.

[0103] Based on this, this application provides a sample analyzer and its control method, which can automatically complete the input of test strip information one by one without the need for a unified input system of information card content, thereby improving the input efficiency of test strip information. In addition, each input of test strip information corresponds one-to-one with the test strip currently in use, thereby improving the accuracy of the test results. At the same time, during each input of test strip information, the sample analyzer can also perform anti-counterfeiting identification of the test strip based on a first identifier, thereby enabling anti-counterfeiting identification of test strips without the need for additional identification devices, thereby reducing equipment costs and making the system structure simpler.

[0104] Firstly, see [the following] Figure 1 As shown, Figure 1 This is a schematic diagram of an optional sample analyzer 100 provided in an embodiment of this application. The sample analyzer 100 includes: a test strip providing device 101, a test strip transferring device 102, a sample application device 103, an information acquisition device 104, and a controller 105. The controller 105 is communicatively connected to the test strip providing device 101, the test strip transferring device 102, the sample application device 103, and the information acquisition device 104. The test strip providing device 101 is used to store test strips to be used. The test strip transferring device 102 is used to take out test strips from the test strip providing device 101. The information acquisition device 104 is used to acquire information on the test strips. The sample application device 103 is used to apply samples to the test strips.

[0105] Among them, see Figure 2 As shown, Figure 2 This is a schematic diagram of an optional test strip provided in an embodiment of this application. The test strip includes a substrate, a detection area disposed on the substrate for dry chemical detection of a sample, a first identifier for indicating manufacturer information, and a second identifier for indicating test strip specification information.

[0106] It should be noted that the controller 105 is used to control the sample application device 103 to apply the sample to the detection area of ​​the test strip for dry chemical reaction, and to control the information acquisition device 104 to acquire the detection information of the detection area, the manufacturer information of the first identifier, and the test strip specification information of the second identifier after the dry chemical reaction is completed. Based on the detection information, manufacturer information, and test strip specification information, the controller 105 obtains and outputs the detection results. Thus, based on the first and second identifiers on the test strip, the controller can automatically complete the input of test strip information one by one without the need for a unified input system of information card content, thereby improving the input efficiency of test strip information. Furthermore, each input of test strip information corresponds one-to-one with the test strip currently in use, thereby improving the accuracy of the detection results.

[0107] Meanwhile, during each input of test strip information, the sample analyzer 100 can also perform anti-counterfeiting identification on the test strip based on the first identifier, thereby enabling anti-counterfeiting identification of the test strip without the need for an additional identification device, thus reducing equipment costs and making the system structure simpler.

[0108] Furthermore, the sample analyzer 100 includes a housing, an information acquisition device 104 is disposed inside the housing, and the controller 105 is also used to control the test strip transfer device 102 to remove the test strip from the test strip supply device 101 before the sample application device 103 applies the sample.

[0109] Furthermore, in one possible embodiment, from Figure 1 It is known that the sample analyzer 100 also includes a first test strip carrier 106 for carrying the test strip.

[0110] The sample analyzer 100 described above includes a first test strip carrier 106. The controller 105 controls the sample application device 103 to apply the sample to the detection area of ​​the test strip for a dry chemical reaction, and controls the information acquisition device 104 to acquire the detection information of the detection area, the manufacturer information of the first identifier, and the test strip specification information of the second identifier after the dry chemical reaction is completed. The process includes the following steps: First, the test strip transfer device 102 moves the test strip from the test strip supply device 101 to the first test strip carrier 106. Then, the sample application device 103 applies the sample to the detection area of ​​the test strip on the first test strip carrier 106 for a dry chemical reaction. Next, after the dry chemical reaction is completed, the information acquisition device 104 acquires information from the test strip on the first test strip carrier 106, thereby acquiring the detection information of the detection area after the dry chemical reaction is completed, the manufacturer information of the first identifier, and the test strip specification information of the second identifier.

[0111] In another possible embodiment, see Figure 3 As shown, Figure 3 This is a schematic diagram of another optional sample analyzer 100 provided in an embodiment of this application. The sample analyzer 100 further includes a second test strip carrier 107 for carrying a test strip to be added and a third test strip carrier 108 for carrying a test strip to be identified.

[0112] The sample analyzer 100 described above includes a second test strip carrier 107 and a third test strip carrier 108. The controller 105 controls the sample application device 103 to apply the sample to the detection area of ​​the test strip for a dry chemical reaction, and controls the information acquisition device 104 to acquire the detection information of the detection area, the manufacturer information of the first identifier, and the test strip specification information of the second identifier after the dry chemical reaction is completed.
