[0031] It should also be understood that the terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and in the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0032] Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] As Figure 1 shown, the present application provides an immunochromatographic analyzer, which includes an optical module 20 and a base. The base is provided with a reagent card holder for carrying a reagent card 100. The optical module 20 is arranged above the reagent card holder for optically detecting the reagent card 100 on the reagent card holder.

[0034] Exemplarily, the base has a photoelectric detection area and an incubation reaction area 101. The reagent card holder extends from the incubation reaction area 101 to the photoelectric detection area, enabling the reagent card 100 to be dropped with liquid in or before the incubation reaction area 101 to cause a reaction in the reagent card 100, and then being transported to the photoelectric detection area, where the optical module 20 detects the reacted reagent card 100. Among them, the reagent card 100 has a sample dropping area 102 and a reaction area 101 communicating with the sample dropping area 102. The sample dropping area 102 is used to drop the sample and the reagent into the reagent card 100. The reaction area 101 is provided with a detection line and a quality control line. After the reaction between the sample and the reagent is completed, the optical module 20 scans the reagent card 100 by using a photoelectric detection method.

[0035] However, in some detection items, the incubation and reaction of the sample and the reagent need to be maintained at a suitable temperature, which is usually in the range of 20°C to 37°C, so as to achieve a better reaction effect. At the same time, the incubation time of the sample and the reagent varies from 3 minutes to 5 minutes. Therefore, for these detection items that need to be incubated at a suitable temperature, if there is no stable and reliable incubation temperature, it will lead to insufficient reaction of the reagent, resulting in waste of the reagent and reduced utilization rate, and affecting the accuracy of the detection result.

[0036] Therefore, the immunochromatographic analyzer of the present application further includes a warming module 10, which can be used to non-contact heat the reagent card 100 and provide heat for the reagent card 100, so that the reagent card 100 can reach the incubation temperature, greatly improving the accuracy of the detection result. Among them, non-contact heating means that after the warming module 10 heats a gas medium such as air, the heat of the heated gas medium such as air is radiated to the surface of the reagent card 100 or directly exchanges heat with the reagent card 100, so that the heat of the gas medium such as air can be slowly transferred to the entire reagent card 100, and heating is realized through non-contact heat exchange. The reagent card 100 can be placed in a heating environment with a larger area, which can avoid uneven heating of the reagent card 100, will not generate local temperature differences, and is conducive to maintaining the reagent card 100 at a stable and reliable incubation temperature, enabling the sample and the reagent on the reagent card 100 to react sufficiently.

[0037] In this embodiment, the warming module 10 is used to heat the gas medium between the reagent card 100 and the warming module 10, so that the heated gas medium can exchange heat with the reagent card 100, thereby realizing the heating of the reagent card 100.

[0038] Exemplarily, at least a part of the incubation module 10 is disposed above the reagent card 100 for heating the gas medium above the reagent card 100, and then using the heated gas medium to heat the reagent card 100, so that the heated gas medium can exchange heat with the reagent card 100, thereby transferring heat to the reagent card 100 and avoiding excessive local temperature.

[0039] Exemplarily, at least a part of the incubation module 10 is disposed on the left side of the reagent card 100 for heating the gas medium on the left side of the reagent card 100, and then using the heated gas medium to heat the reagent card 100, so that the heated gas medium can exchange heat with the reagent card 100, thereby uniformly transferring heat to the reagent card 100 and avoiding excessive local temperature.

[0040] Exemplarily, at least a part of the incubation module 10 is disposed on the right side of the reagent card 100 for heating the gas medium on the right side of the reagent card 100, and then using the heated gas medium to heat the reagent card 100, so that the heated gas medium can exchange heat with the reagent card 100, thereby uniformly transferring heat to the reagent card 100 and avoiding excessive local temperature.

[0041] Exemplarily, at least a part of the incubation module 10 is disposed below the reagent card 100 for heating the gas medium below the reagent card 100, and then using the heated gas medium to heat the reagent card 100, so that the heated gas medium can exchange heat with the reagent card 100, thereby uniformly transferring heat to the reagent card 100 and avoiding excessive local temperature.

[0042] Exemplarily, the incubation module 10 is formed with an incubation chamber 10a. The incubation module 10 can heat the gas medium in the incubation chamber 10a, so that the heated gas medium can exchange heat with the reagent card 100, thereby uniformly heating the reagent card 100 in the incubation chamber 10a. Since the reagent card 100 is completely separated from the heating unit 11 of the incubation module 10, non-contact gas heating is fully realized, and excessive local temperature is avoided.

[0043] In an alternative embodiment, as Figure 2 and Figure 3As shown, the incubation module 10 includes a heating unit 11. The heating unit 11 is used to heat the gas medium between the heating unit 11 and the reagent card 100, so that the heated gas medium can exchange heat with the reagent card 100, thereby uniformly heating the reagent card 100. Non-contact gas heating is achieved, effectively solving the problem of uneven heating of the reagent card 100 during the heating process, making the entire reagent card 100 uniformly heated without gradient, ensuring effective incubation, with a simple and reliable structure, low price cost, and being suitable for large-scale use.

[0044] In an optional embodiment, the heating unit 11 is arranged on one side of the reagent card holder and is used to heat the gas medium on one side or the periphery of the reagent card 100, so that the heated gas medium can heat the reagent card 100, and the heating of the reagent card 100 is realized by means of the heated gas medium, etc., to ensure effective incubation. Among them, the gas medium on one side or the periphery of the reagent card 100 includes the gas medium on the left side, the right side and even the periphery of the reagent card 100. The gas medium includes but is not limited to air, and the present application does not limit it.

[0045] In an optional embodiment, the heating unit 11 is arranged above the reagent card holder and is used to heat the gas medium above the reagent card 100, so that the gas medium can form a hot gas flow and uniformly heat the reagent card 100, thereby realizing non-contact gas heating, enabling the heated gas medium to exchange heat with the reagent card 100, and heating or realizing heat transfer to the reagent card 100.

[0046] In an optional embodiment, the incubation module 10 includes an incubation chamber. The incubation chamber is connected to the reagent card holder and forms an incubation chamber 10a for incubating the reagent card 100. The heating unit 11 is used to heat the gas medium in the incubation chamber 10a, so that the hot gas flow in the incubation chamber 10a can uniformly heat the reagent card 100, and even the hot gas flow can be locked in the incubation chamber 10a to reduce the outflow of the hot gas flow and save energy.

[0047] In an alternative embodiment, the incubation chamber includes a heat-conducting cover 12. The heat-conducting cover 12 extends along the length direction of the reagent card 100. At least a part of the heating unit 11 is arranged on the heat-conducting cover 12, and the heat-conducting cover 12 can be heated, so that the heat-conducting cover 12 can fully heat the gas medium in the incubation chamber 10a, and then transfer the heat to the reagent card 100 through the gas medium to heat the reagent card 100. Wherein, the heating unit 11 preheats the heat-conducting cover 12 first, and then heats the gas medium in the incubation chamber 10a through the heat-conducting cover 12, so that the heated gas medium can effectively heat the reagent card 100. The incubation chamber 10a is formed by using the heat-conducting cover 12, which restricts the air flow speed in the incubation chamber 10a to a certain extent, so that the contact area between the reagent card 100 and the gas medium is large and the heat loss is small.

[0048] In an alternative embodiment, the heat-conducting cover 12 is in a U-shaped structure. The reagent card holder has a conveying groove for conveying the reagent card 100. The two ends of the heat-conducting cover 12 are respectively connected to both sides of the conveying groove. The heating unit 11 is arranged at the upper end or the peripheral side of the heat-conducting cover 12, which is not only convenient for installation and fixation, but also can export the heat generated by the heating unit 11 from the U-shaped opening below the heat-conducting cover 12, so that the heat can heat the gas medium in the U-shaped structure, and then use the heated gas medium to heat the reagent card 100 in the incubation chamber 10a. Wherein, the incubation chamber 10a formed by the U-shaped structure and the reagent card holder enables the reagent card 100 to be heated in a non-contact manner in the incubation chamber 10a.

[0049] In an alternative embodiment, the heat-conducting cover 12 is in a hollow structure. The reagent card holder is arranged in the hollow structure of the heat-conducting cover 12. The heating unit 11 is arranged on the inner wall or the outer wall of the hollow structure, so that the heating unit 11 can heat the gas medium in the hollow structure, and then use the heated gas medium to heat the reagent card 100 in the incubation chamber 10a. Wherein, the incubation chamber 10a formed by the hollow structure enables the reagent card 100 to be heated in a non-contact manner in the incubation chamber 10a.

[0050] In an alternative embodiment, the maximum distance between the heat-conducting cover 12 and the reagent card 100 is between 2 and 5 mm, which can not only ensure that the heating temperature gradient of the gas medium at each position of the reagent card 100 is small, so that the reagent card 100 is heated evenly; but also ensure the heating rate of the reagent card 100. Within this distance range, the reagent card 100 can rise from a low temperature similar to 5°C to 15°C to an incubation temperature similar to 25°C within 3 to 5 minutes, and then maintain the incubation and reaction at this incubation temperature.

[0051] In an alternative embodiment, the heating unit 11 includes a heating sheet, and the length of the heating sheet is adapted to the length of the heat conducting cover 12 to ensure the heating power of the heating unit 11 at each position of the heat conducting cover 12, so that the heating unit 11 can be evenly distributed on the heat conducting cover 12. Then, the heat energy generated by the heating unit 11 is transferred to the heat conducting cover 12, and the gas medium flows through the inside of the heat conducting cover 12 to exchange heat with the heat conducting cover 12, so that the temperature of the gas medium rises. Then, the heat conducting cover 12 can heat the gas medium in the incubation chamber 10a, so as to heat the reagent card 100 in the incubation chamber 10a by using the heated gas medium.

[0052] It should be noted that the heat conducting cover 12 can be made of common heat conducting metals, such as aluminum alloy, copper alloy, stainless steel, etc., and the present application does not limit it.

[0053] In an alternative embodiment, the heat conducting cover 12 is constructed of a common concave character profile, and its processing and manufacturing are simple. Among them, the heating sheet is attached above the heat conducting cover 12. Among them, the heating unit 11 can also be set into an integral structure with the heat conducting cover 12, such as being embedded in the heat conducting cover 12; the heating unit 11 can also be a heating wire or a heating rod, etc., and the present application does not limit it.

[0054] In an alternative embodiment, the incubation chamber further includes a heat insulation member 13, the heat insulation member 13 is arranged outside the heat conducting cover 12, the heating unit 11 is arranged inside the heat insulation member 13 or the heat conducting cover 12, or the heating unit 11 is arranged between the heat insulation member 13 and the heat conducting cover 12, reducing the heat transfer of the heating unit 11 to the outside, enabling the incubation chamber 10a to achieve a good heat insulation effect, being beneficial to the heat insulation of the heating unit 11, and achieving an energy-saving effect.

[0055] In an alternative embodiment, the heat insulation member 13 includes heat insulation cotton, and the heat insulation cotton wraps the outside of the heating unit 11 to prevent the heat of the heating unit 11 from dissipating outward, ensuring that the heat of the heating unit 11 can be transferred to the heat conducting cover 12, so that the temperature of the heat conducting cover 12 can be stable, and thus the gas medium in the heat conducting cover 12 can be quickly heated.

[0056] It should be noted that the heat insulation member 13 can also be other heat insulation materials, such as a film, etc., and its main purpose is to be able to achieve the effects of heat preservation and heat dissipation isolation, and the present application does not limit it.

[0057] In an alternative embodiment, such as Figures 2 to 4As shown, the incubation chamber includes a temperature control system. The temperature control system controls the temperature in the incubation chamber 10a through the PID control method, enabling the temperature of the reagent card 100 to rise steadily and be maintained at the incubation temperature, making it easier to control the incubation temperature. Among them, the PID control method is a predictive control method that can adjust the power of the heating unit 11 in real time and smoothly to reach the target incubation temperature and achieve precise temperature control.

[0058] In an alternative embodiment, the temperature control system includes a PID controller 15 and a temperature sensor 14. The PID controller 15 is electrically connected to the temperature sensor 14. The temperature sensor 14 is used to collect the temperature of the heating unit 11 and / or outside the immunoassay analyzer, enabling the PID controller 15 to use the PID control method to control the real-time power of the heating unit 11 in real time according to the temperature collected by the temperature sensor 14, so as to achieve closed-loop temperature control and control the temperature in the incubation chamber 10a within ±1°C to achieve constant-temperature incubation.

[0059] In an alternative embodiment, the temperature sensor 14 includes a first sensor 141. The first sensor 141 is arranged on the heating unit 11 and is used to collect the temperature of the heating unit 11 and / or the heat conduction cover 12, enabling the PID controller 15 to control the operation of the heating unit 11 according to the temperature collected by the first sensor 141, so as to heat the gas medium in the incubation chamber 10a, so that the heated gas medium can exchange heat with the reagent card 100 and be maintained at the incubation temperature.

[0060] In an alternative embodiment, the temperature sensor 14 includes a second sensor 142. The second sensor 142 is arranged outside the incubation chamber 10a and is used to collect the ambient air temperature outside the immunoassay analyzer, so that the PID controller 15 can automatically turn on the heating function of the heating unit 11 according to the temperature collected by the second sensor 142.

[0061] Exemplarily, the first sensor 141 is arranged in the middle of the heating unit 11 and covered with heat-insulating cotton, enabling the first sensor 141 to accurately measure the surface temperature of the heat conduction cover 12, so as to achieve precise temperature control.

[0062] In an alternative embodiment, the PID controller 15 periodically collects the temperature value of the second sensor 142 to determine whether the ambient air temperature outside the immunochromatographic analyzer is lower than a preset temperature value. When the ambient air temperature is higher than the preset temperature value, the heating function of the heating unit 11 does not need to be turned on; if the ambient air temperature is lower than the preset temperature value, the PID controller 15 automatically turns on the heating function of the heating unit 11, so that the stability of the incubation chamber 10a can be maintained in advance at the incubation temperature value, so that when the reagent card is transported into the incubation chamber 10a, the timing and incubation reaction can be started.

[0063] Wherein, after the PID controller 15 turns on the heating function of the heating unit 11, the PID controller 15 uses the PID control method to control the real-time power of the heating unit 11 in real time according to the temperature value collected by the first sensor 141, and controls the ambient temperature in the incubation chamber 10a within ±1°C to achieve constant temperature incubation.

[0064] In an alternative embodiment, the temperature control system includes a heating drive circuit 16. The PID controller 15 is electrically connected to the heating unit 11 through the heating drive circuit 16, so that the PID controller 15 can use the PID control method to control the duty cycle of the heating drive circuit 16 in real time according to the temperature collected by the first sensor 141, so as to adjust the power of the heating unit 11 in real time, so that closed-loop control of the temperature can be achieved, and the ambient temperature in the incubation chamber 10a can be controlled within ±1°C to achieve constant temperature incubation.

[0065] In an alternative embodiment, the temperature control system includes an AD converter 17. The AD converter 17 is used to convert the analog signals collected by the first sensor 141 and the second sensor 142 into digital signals, so that the PID controller 15 can read the digital signals after AD conversion, thereby controlling the duty cycle of the heating drive circuit 16.

[0066] In an alternative embodiment, as Figures 1 to 4 shown, the incubation module 10 and the optical module 20 are arranged in sequence along the conveying direction of the reagent card 100, and the incubation module 10 is arranged upstream of the optical module 20, so that the optical module 20 can scan the reagent card 100 after the incubation reaction is completed, so as to realize automatic timed incubation and automatic detection; this can not only enable the immunochromatographic analyzer to complete automatic timed heating incubation, but also realize photoelectric detection immediately after the incubation is completed; at the same time, this process does not require manual operation, greatly improving the efficiency of the detection operation, and also avoiding the time delay caused by manual timing and manual card insertion.

[0067] In an alternative embodiment, the incubation module 10 and the optical module 20 are on the same straight line, and the incubation module 10 is located at the front end of the optical module 20.
