The application provides a sample analyzer, which is applied to the field of medical treatment or biochemical analysis. A more common sample analyzer may be an immunoassay analyzer; the sample analyzer may also be other clinical laboratory equipment.
Sample analyzers may be used to perform fluorescence detection on a sample. The immunity analyzer comprises a transportation module, a sampling module, a reagent module, a reaction module, a magnetic separation module and a fluorescence detection module. When the device is used, an original sample is transferred to the sampling module through the transportation module, the original sample is quantitatively sampled by utilizing the sampling of the sampling module, and the original sample is transferred to the reaction module to wait for reaction. The reagent module is used for containing and preparing a reagent required by sample detection, the transportation module transports the reagent which is required to be added into the sample to the reagent station, and a reagent needle of the reagent module absorbs the corresponding reagent and accurately and quantitatively adds the corresponding reagent into a reaction disc of the reaction module, wherein the reagent comprises magnetic beads with specific antibodies.
The sampling needle adds the original sample to the reaction plate, where the original sample is incubated for a period of time in order to bind the antigen in the original sample to the specific antibody in the reagent. After incubation, the magnetic separation module carries out magnetic separation on the incubated sample mixture, in the magnetic separation module, cells which do not react with the specific antibodies are separated through an immunomagnetic bead separation technology, and a magnetic bead composition obtained through magnetic separation is cleaned, so that reagents and other wastes which are not combined with the magnetic beads in a reaction disk are cleaned, and a sample to be detected is obtained. The fluorescence detection module detects a sample to be detected and converts photoelectric data to obtain detection data.
The sample analyzer may perform various items of detection, such as seven items of detection including blood coagulation (including plasma Prothrombin time, PT), activated partial Prothrombin time (activated partial thromboplastin time, APTT), fibrinogen (FIB), thrombin Time (TTs), D-Dimer (D-D), antithrombin III (AT-III), fibrinogen degradation products (fructified-1, 6-diphosphonate, FDP)) and the like.
The sample analyzer may be used to perform the card swiping method of the reagent card of any of the following embodiments.
The application provides a reagent card swiping method which is applied to a sample analyzer. Referring to fig. 1, fig. 1 is a flow chart of a first embodiment of a card swiping method of a reagent card provided in the present application. Specifically, the method includes the following steps S101 to S103.
Step S101: and when the sample analyzer starts a card swiping process, the card swiping operation is sequentially carried out on the plurality of reagent cards.
Reagents of different items are used in the sample analyzer during the performance of a portion of the item test (e.g., a seven-item blood clotting test), however, a card swiping operation is required before each reagent cartridge is used to load the reagents. In some embodiments, a user needs to click a card swiping button of a computer interface first, however, in the prior art, after entering a card swiping process, a card swiping operation on a reagent card needs to be completed within a certain period of time, and the existing reagent card swiping process only supports 1 card swiping, when a plurality of project reagents need to be loaded, the card swiping process needs to be repeatedly clicked repeatedly, so that the user operation is inconvenient. Especially when the instrument is far away from the computer, the user needs to fast run to the instrument to brush 1 card after clicking 1 card swiping at the interface, running back and forth and inconvenience are caused, and the validity of the single-time card swiping can not be determined.
In the card swiping process of the reagent card, card swiping operation can be performed on a plurality of reagent cards at the same time, namely, a single-round card swiping process can continuously swipe an unlimited amount of Zhang Shiji cards, including effective reagent cards (reagents of the same item and reagent cards of different items), and illustratively, a card swiping button can be clicked in a human-computer interaction interface, after entering the card swiping process, a plurality of reagent cards can be continuously swiped, so that card swiping efficiency is improved, and the possibility of card swiping failure is reduced.
Step S102: and reading the reagent card information in each reagent card one by one in the process of executing a card swiping flow on the reagent card by the sample analyzer.
Related information is pre-stored in each reagent card, and the information pre-stored in the reagent card can be read in the process of swiping the card by the sample analyzer. In the process that the sample analyzer performs the card swiping process on the reagent card, the sample analyzer reads the reagent card information in the reagent card every time when the sample analyzer swipes one reagent card, that is, the reagent card information in each reagent card can be read while continuously swiping the reagent card.
Step S103: the reagent card information is displayed in an information window of the sample analyzer.
When the sample analyzer reads one reagent card, reagent card information is displayed in an information window of the sample analyzer, so that the reagent card information is visualized, and a user can conveniently view the reagent card information while continuously swiping the reagent card. When the information of the reagent cards is more, a plurality of pieces of information of the reagent cards can be displayed in the information window according to a specific rule, and when all the information of the reagent cards cannot be completely displayed in the same information window, other information of the reagent cards can be displayed in a sliding scroll bar mode.
Through the embodiment, the card swiping operation is sequentially performed on a plurality of reagent cards, and the information after card reading is displayed in the information window, so that in the card swiping process, the traditional repeated cycle mode of single-click card swiping is replaced by the continuous mode of reagent card swiping, the card swiping efficiency is improved, and the possibility of card swiping failure is reduced.
Referring to fig. 2, fig. 2 is a flowchart of step S103 in fig. 1. Specifically, the following steps S201 to S203 are included.
Step S201: based on the reagent card information of the reagent card, the validity of the reagent card is determined.
After the sample analyzer reads the reagent card information of the reagent card, the sample analyzer may determine the validity of the reagent card based on the reagent card information. The validity of the reagent card can be determined according to the item type of the reagent card, whether the reagent card is the reagent card or not, and whether the reagent card is the used reagent card or not. Illustratively, when the test items are Fibrinogen (FIB) and plasma Prothrombin Time (PT), the reagent card swiped is considered to be a valid reagent card when the reagent card swiped is Fibrinogen (FIB) and plasma Prothrombin Time (PT), and the reagent card swiped is considered to be an invalid reagent card when the reagent card swiped is Thrombin Time (TT) and fibrin (raw) degradation product (FDP); when the swiped reagent card is a used reagent card, the reagent card can be considered as an invalid reagent card; when the "reagent card" swiped is not a reagent card for the sample analyzer, the swiped card may be considered an invalid reagent card.
Step S202: and if the reagent card is detected to be an effective reagent card, displaying the reagent card information of the effective reagent card in an information window of the sample analyzer in a first display mode.
In order to facilitate a user to check whether the reagent card is an effective reagent card from the information window after the reagent card information is read, the reagent card information of the effective reagent card and the reagent card information of the ineffective reagent card can be respectively displayed in the information window in different display modes.
When the reagent card is detected to be a valid reagent card, the reagent card is displayed in an information window of the sample analyzer in a first display mode. The first display mode may be a font of a specific color or a font of a different size.
Step S203: and if the reagent card is detected to be an invalid reagent card, displaying the reagent card information of the invalid reagent card in an information window of the sample analyzer in a second display mode.
The second display mode may be a font of a specific color or a font of a different size. For example, when the first display mode is a black font, the second display mode may be a red font; or the fonts of the first display mode are larger than the fonts of the second display mode; or when the second display mode can be an error code, the reagent card information of the invalid reagent card is displayed in the information window in the form of the error code, so that the validity of the swiped reagent card can be checked in the information window, and the reagent card information can be conveniently processed by a user.
In one embodiment, after determining the validity of the reagent card based on the reagent card information of the reagent card (step S201), the method includes: if the reagent card is detected to be an effective reagent card, the sample analyzer sends out first prompt information; and if the reagent card is detected to be an invalid reagent card, the sample analyzer sends out second prompt information.
The first prompt information and the second prompt information may be alarm prompt information, and the first prompt information may be one-sound dripping sound, and the second prompt information may be two-sound short dripping sound of the sample analyzer. In other embodiments, the first prompt message and the second prompt message may be other prompt sounds, which are not illustrated herein. Therefore, the validity of the reagent card can be judged based on the prompt information in the process of swiping the reagent card, and the reagent card can be conveniently processed by a user.
Referring to fig. 3, fig. 3 is a flow chart of a second embodiment of a card swiping method of a reagent card provided in the present application. Specifically, the following steps S301 to S305 are included.
Step S301: and when the sample analyzer starts a card swiping process, the card swiping operation is sequentially carried out on the plurality of reagent cards.
Step S302: and reading the reagent card information in each reagent card one by one in the process of executing a card swiping flow on the reagent card by the sample analyzer.
Step S303: the reagent card information is displayed in an information window of the sample analyzer.
The specific embodiments of step S301 to step S303 are the same as those of step S101 to step S103, and are not described herein.
Step S304: and if the prothrombin time reagent card information is detected to exist in the reagent card information, comparing the international sensitivity index of the reagent card in the prothrombin time reagent card information with the current international sensitivity index of the sample analyzer.
The international sensitivity index (International Sensitivity Index, ISI) is obtained by strictly calibrating a plurality of blood plasma with different blood coagulation factor levels with an International Reference Product (IRP), obtaining a regression slope through regression analysis, representing the sensitivity of the thromboplastin reagent to the deficiency of the blood coagulation factor, wherein the lower the international sensitivity index value is, the higher the sensitivity is, the imported thromboplastin reagent is marked with the international sensitivity index value, and the international normalized ratio (International Normalized Ratio, INR) value can be calculated by using the international sensitivity index value, so that the comparability of the results among different reagents is established. The minimum value of the international sensitivity index is 1.0 in theory, and the best value in the market at present is generally about 1.30. When prothrombin time reagent card information exists in the reagent card information, detecting whether the international sensitivity index of the reagent card is the same as the current international sensitivity index of the sample analyzer.
Step S305: when the current international sensitivity index is different from the international sensitivity index of the reagent card, the current international sensitivity index is updated by using the international sensitivity index of the reagent card.
When the current international sensitivity index is different from the international sensitivity index of the reagent card, the value of the current international sensitivity index is required to be changed into the value of the international sensitivity index of the reagent card. Illustratively, if the current international sensitivity index has a value of 1.1 and the reagent card international sensitivity index has a value of 1.2, the current international sensitivity index is changed to a value of 1.2.

In one embodiment, when the current international sensitivity index is different from the international sensitivity index of the reagent card, the step of updating the current international sensitivity index by using the international sensitivity index of the reagent card (step S305) includes: if the international sensitivity index of the plurality of reagent cards is different from the current international sensitivity index, responding to the operation instruction of the user, and selecting any international sensitivity index of the reagent cards to update the current international sensitivity index.
The user's operation instructions may include single click, double click, drag, slide, etc. instructions for the button. Of course, the operation instruction may also be a voice operation. For example, when the preset voice information is recognized, the user is considered to make an operation instruction for the prompt information. After the sample analyzer receives the operation instruction, the sample analyzer may select the international sensitivity index of the reagent card selected by the operation instruction based on the operation instruction of the user to update the current international sensitivity index.
In one embodiment, a method for swiping a reagent card includes: and ending the card swiping flow when all the current international sensitivity indexes are identical to the international sensitivity indexes of the reagent card.
In one embodiment, after reagent card information is displayed in the information window of the sample analyzer (step S103), the card swiping method of the reagent card includes: if the prothrombin time reagent card information is detected to be not contained in the reagent card information, ending the card swiping process.
In one embodiment, after reagent card information is displayed in the information window of the sample analyzer (step S103), the card swiping method of the reagent card includes: displaying the current international sensitivity index of the sample analyzer in a man-machine interaction interface of the sample analyzer; and responding to an operation instruction of a user, and updating the current international sensitivity index in the human-computer interaction interface based on the prothrombin time reagent card information in the reagent card information.
The sample analyzer is provided with a man-machine interaction interface, the man-machine interaction interface can be used for displaying project related information, and the man-machine interaction interface can also be used for realizing information interaction between a user and the sample analyzer. In this embodiment, the human-computer interaction interface is used to display the current international sensitivity index of the sample analyzer, and so on. The user's operation instructions may include single click, double click, drag, slide, etc. instructions for the button. Of course, the operation instruction may also be a voice operation. For example, when the preset voice information is recognized, the user is considered to make an operation instruction for the prompt information. After the sample analyzer receives the operation instruction, the sample analyzer can enter an editing interface of the international sensitivity index of the reagent card based on the operation instruction of the user, and at the moment, the user can update the current international sensitivity index in the human-computer interaction interface based on the international sensitivity index of the reagent card in the prothrombin time reagent card information. For example, when the value of the international sensitivity index of the reagent card is 1.2 and the value of the current international sensitivity index is 1.1, the user can change the value of the international sensitivity index from 1.1 to 1.2 in the human-computer interaction interface. Through the implementation mode, the user can update the current international sensitivity index based on the international sensitivity index of the reagent card by himself, so that the card swiping efficiency is improved, and the possibility of card swiping failure is reduced.
