In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying 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 said features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0035] The following will describe in detail some embodiments of the present application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0036] As Figures 1 to 3 shown, according to the first aspect of the present application, the present application provides an immunochromatographic analyzer 100, which includes an optical module 10 and a base 20. A placement groove 21 for placing a reagent card 200 is provided on the base 20. The placement groove 21 extends along a first direction of the base 20. The optical module 10 is disposed above the placement groove 21 and can be positionally adjusted relative to the base 20 in a second direction to adjust the position of the light spot emitted by the optical module 10 to the reagent card 200, so that the detection light spot falls on the detection area of the reagent card 200 to improve the detection accuracy.

[0037] In this embodiment, the optical module 10 includes at least one optical component. When the number of optical components is greater than two, each optical component can be individually positionally adjusted relative to the base 20 in the second direction to avoid mutual influence between them. Among them, the second direction and the first direction are arranged at an angle to ensure that each optical component can independently adjust its position in a second direction different from the first direction, so that the detection light spot falls on the detection area of the reagent card 200 and the detection accuracy is improved.

[0038] After adopting the above technical solution, since each optical component can be individually adjusted in position relative to the base 20 in the second direction, that is, each optical component is an independent module and they will not affect each other during the position adjustment process, it is ensured that the detection light spot can fall on the detection area of the reagent card 200, improving the detection accuracy. In addition, in order to reduce the probability of the detection light spot falling outside the detection area, the width of the detection module of each optical component is smaller than the width of the detection area of the reagent card 200, and then the position of the optical component can be adjusted to make the detection light spot fall on the middle position of the detection area of the reagent card 200, so as to reduce the interference of background signals and improve the detection accuracy.

[0039] In an optional embodiment, the optical module 10 includes at least one of a colloidal gold module for performing colloidal gold immunoassay detection and a fluorescence module for performing fluorescence immunoassay detection. When the number of optical modules 10 is greater than two, each optical module 10 can be individually adjusted in position relative to the base 20 in the second direction, avoiding mutual influence between them. Among them, the second direction and the first direction are arranged at an angle to ensure that each optical component can independently adjust its position in a second direction different from the first direction, so that the detection light spot falls on the detection area of the reagent card 200, improving the detection accuracy.

[0040] In an optional embodiment, the number of optical components is at least two, and each optical component can be individually adjusted in position relative to the base 20 in the second direction, avoiding mutual influence between them. Among them, the second direction and the first direction are arranged at an angle to ensure that each optical component can independently adjust its position in a second direction different from the first direction, so that the detection light spot falls on the detection area of the reagent card 200, improving the detection accuracy.

[0041] It should be noted that at least two optical components can be the same optical module 10, such as all being a colloidal gold module, a fluorescence module or other optical modules 10; at least two optical components can also be different optical modules 10, such as a part of them being a colloidal gold module and another part being a fluorescence module or other optical modules 10, which is not limited in this application.

[0042] In an alternative embodiment, the optical module 10 includes a first optical component 11 and a second optical component 12. A first adjusting member 30 is connected between the first optical component 11 and the base 20, and a second adjusting member 40 is connected between the second optical component 12 and the first optical component 11. Such that the first optical component 11 can be positionally adjusted relative to the base 20 in a second direction by the first adjusting member 30, and the second optical component 12 can be positionally adjusted relative to the base 20 in the second direction by the second adjusting member 40 or the first adjusting member 30, so as to ensure that the positional adjustments between the first optical component 11 and the second optical component 12 do not affect each other, both can be independently adjusted, and the detection light spot can fall on the detection area of the reagent card 200, thereby improving the detection accuracy.

[0043] In an alternative embodiment, the optical module 10 includes a first optical component 11 and a second optical component 12. A first adjusting member 30 is connected between the first optical component 11 and the base 20, and a second adjusting member 40 is connected between the second optical component 12 and the base 20. Such that the first optical component 11 can be positionally adjusted relative to the base 20 in a second direction by the first adjusting member 30, and the second optical component 12 can be positionally adjusted relative to the base 20 in the second direction by the second adjusting member 40, so as to ensure that the positional adjustments between the first optical component 11 and the second optical component 12 do not affect each other, both can be independently adjusted, and the detection light spot can fall on the detection area of the reagent card 200, thereby improving the detection accuracy.

[0044] Exemplarily, a first adjusting portion is provided on the first adjusting member 30, and a second adjusting portion is provided on the base 20. The optical module 10 is mounted on the first adjusting member 30, and the first adjusting portion is connected to the second adjusting portion for adjusting the position of the optical module 10 on the base 20 so that the detection light spot can fall on the detection area of the reagent card 200, thereby improving the detection accuracy.

[0045] In an alternative embodiment, the first adjustment portion includes a first locking member 32 and a first kidney-shaped hole 31 formed in the first adjustment member 30. The second adjustment portion includes a first locking hole 22 provided on the base 20. The first locking member 32 passes through the first kidney-shaped hole 31 and is connected to the first locking hole 22. When it is necessary to adjust the position of the optical module 10, the connection between the first locking member 32 and the first locking hole 22 is loosened, so that the first locking member 32 can move along the length direction of the first kidney-shaped hole 31, and this length direction is the second direction perpendicular to the first direction, realizing the position adjustment of the detection light spot and the detection area; when the detection light spot falls on the middle position of the detection area, that is, the position adjustment of the optical module 10 is completed, the connection between the first locking member 32 and the first locking hole 22 is tightened, so that the first adjustment member 30 can be firmly fixed on the base 20, avoiding the first adjustment member 30 moving relative to the base 20 during the detection process, thereby affecting the detection accuracy.

[0046] In an alternative embodiment, the first adjustment portion further includes a first elastic member. One end of the first elastic member abuts against the first locking member 32, and the other end of the first elastic member abuts against the first adjustment member 30, so as to ensure the stability of the connection between the first adjustment member 30 and the base 20 after the adjustment is completed. At the same time, when the first locking member 32 and the first locking hole 22 are loosened, it can avoid the instability of the first adjustment member 30 driving the optical module 10 to adjust the position. That is, the first elastic member always applies a pressure towards the first adjustment member 30 when the first adjustment member 30 moves relative to the base 20, ensuring the continuity of the applied pressure and preventing the first adjustment member 30 from shaking due to the loosening of the first locking member 32 and the first locking hole 22.

[0049] In an alternative embodiment, the first adjustment member 30 further includes a third connection surface 30c, and the third connection surface 30c is perpendicular to the first connection surface 30a and the second connection surface 30b. Two adjacent surfaces of the optical module 10 are fixed on the first connection surface 30a and the third connection surface 30c to ensure the stability of the connection between the optical module 10 and the first adjustment member 30.

The first adjusting member 30 is connected between one of the fluorescence module and the colloidal gold module and the base 20, and the second adjusting member 40 is connected between the colloidal gold module and the fluorescence module; alternatively, the second adjusting member 40 is connected between the other of the fluorescence module and the colloidal gold module and the base 20, so that the fluorescence module and the colloidal gold module can independently adjust their positions relative to the base 20 through the first adjusting member 30 and the second adjusting member 40 respectively.

The structure is simple and the operation is convenient.

[0054] In an alternative embodiment, a third adjusting portion is provided on the first connecting structure 41, and a fourth adjusting portion is provided on the second connecting structure 42. The third adjusting portion is connected to the fourth adjusting portion for adjusting the relative position between the colloidal gold module and the fluorescence module, so that the detection light spot formed by the colloidal gold module can fall on the detection area of the reagent card 200, thereby improving the detection accuracy.

[0055] In an optional embodiment, the third adjustment part includes a second locking hole 411 provided on the first connection structure 41, the fourth adjustment part includes a second locking member 422 and a second waist-shaped hole 421 formed on the second connection structure 42, and the second locking member 422 passes through the second waist-shaped hole 421 and is connected to the second locking hole 411. When it is necessary to adjust the position of the colloidal gold module, the connection between the second locking member 422 and the second locking hole 411 is loosened, so that the second locking member 422 can move along the length direction of the second waist-shaped hole 421, and this length direction is the second direction perpendicular to the first direction, realizing the position adjustment of the detection light spot and the detection area; when the detection light spot formed by the colloidal gold module falls on the middle position of the detection area, that is, the position adjustment of the colloidal gold module is completed, the connection between the second locking member 422 and the second locking hole 411 is tightened, so that the second connection structure 42 can be firmly fixed on the first connection structure 41, avoiding the second connection structure 42 moving relative to the first connection structure 41 during the detection process, thereby affecting the detection accuracy.

One end of the second elastic member abuts against the second locking member 422, and the other end of the second elastic member abuts against the second connection structure 42 to ensure the stability of the connection between the second connection structure 42 and the base 20 after the adjustment is completed. At the same time, when the second locking member 422 and the second locking hole 411 are loosened, the stability of the second connection structure 42 driving the colloidal gold module to adjust the position can be avoided, that is, the second elastic member always applies pressure to the second connection structure 42 when the second connection structure 42 moves relative to the base 20, ensuring the continuity of the applied pressure and preventing the second connection structure 42 from shaking due to the loosening of the second locking member 422 and the second locking hole 411.
