[0055] In some embodiments, the first light source 311 and the second light source 312 refer to devices or components that can emit light, such as laser emitters, without limitation.

[0056] A first optical path channel 410 is provided in the first light guide member 400, and the first optical path channel 410 is connected to the first light source 311, so that the light emitted by the first light source 311 passes through the first optical path channel 410 and is emitted to the reaction unit of the first annular groove 210 to form scattered light. In other words, the light emitted by the first optical path channel 410 is emitted from the outside of the first annular groove 210 to the inside of the first annular groove 210, so that it can be received by the first detection member 321 located in the accommodating space, thereby realizing the scattered light detection function of the reaction unit on the first annular groove 210.

[0057] Similarly, a second light path channel 510 is provided in the second light guide member 500, and the second light path channel 510 is connected to the second light source 312, so that the light emitted by the second light source 312 passes through the second light path channel 510 and is emitted to the reaction unit of the second annular groove 220 to form scattered light. In other words, the light emitted by the second light path channel 510 is emitted from the second annular groove 220 to the outside of the second annular groove 220, so that it can be received by the second detection member 322 located in the accommodating space, thereby realizing the scattered light detection function of the reaction unit on the second annular groove 220.

[0058] The optical path module of the present application includes a first light guide 400 and a second light guide 500, wherein the first light guide 400 has a first light path channel 410, the second light guide 500 has a second light path channel 510, the carrier 200 is provided with a concentric first annular groove 210 and a second annular groove 220, the first annular groove 210 is arranged on the periphery of the second annular groove 220, the first annular groove 210 and the second annular groove 220 are used to carry a reaction unit, the reaction unit is used for mixing a sample with a reagent to react, there is a accommodating space between the reaction unit on the first annular groove 210 and the reaction unit on the second annular groove 220, the first detection member 321 and the second detection member 322 are arranged in the accommodating space, and the first light guide 400 is arranged The periphery of the first annular groove 210 is connected to the first light source 311, and is used to guide the light emitted by the first light source 311 into the first optical path channel 410 to the reaction unit of the first annular groove 210 to form scattered light, so as to be received by the first detection component 321; the second light guide component 500 is arranged in the inner periphery of the second annular groove 220 and is connected to the second light source 312, and is used to guide the light emitted by the second light source 312 into the second optical path channel 510 to the reaction unit of the second annular groove 220 to form scattered light, so as to be received by the second detection component 322 located in the accommodating space, thereby enabling the reaction unit on the first annular groove 210 and the reaction unit on the second annular groove 220 to perform light detection functions, thereby improving the detection efficiency.

[0059] In some optional embodiments, a heat preservation structure 230 is provided in the accommodating space, and the first detection member 321 and the second detection member 322 are both provided in the heat preservation structure 230 . The heat preservation structure 230 is used to keep the ambient temperature of the first detection member 321 and the second detection member 322 within a preset temperature value.

[0060] During implementation, the required temperature of the mixed solution contained in the reaction unit is inconsistent with the working temperature of the first detection component 321 and the second detection component 322. For example, the mixed solution needs to be maintained at a temperature range of 36 to 38 degrees Celsius, while the working temperature of the first detection component 321 and the second detection component 322 needs to be maintained at a temperature range of 20 to 22 degrees Celsius. Among them, the temperature change has a great influence on the working stability and detection accuracy of the detection components, and the first detection component 321 and the second detection component 322 need to be heat-insulated to ensure the detection accuracy.

[0061] In some optional embodiments, the optical path module further includes a third light guide 600 and a fourth light guide 700;

[0062] The third light guide member 600 and the fourth light guide member 700 are disposed in the accommodation space;

[0063] The third light guide 600 has a third light path channel 610 corresponding to the first light path channel 410 and connected to the first detection element 321, and the third light path channel 610 is arranged at a preset angle with the optical axis of the outgoing light of the first light path channel 410;

[0064] The fourth light guide member 700 has a fourth light path channel 710 corresponding to the second light path channel 510 and connected to the second detection member 322 . The fourth light path channel 710 and the optical axis of the outgoing light of the second light path channel 510 are arranged at a preset angle.

[0065] The third light guide member 600 has a third light path channel 610, one end of the third light path channel 610 is connected to the first detection member 321, the other end of the third light path channel 610 corresponds to the first annular groove 210 spaced between the first light path channel 410, and the third light path channel 610 and the optical axis of the outgoing light of the first light path channel 410 are arranged at a preset angle, so that the light emitted by the first light path channel 410 is irradiated on the reaction unit of the first annular groove 210 to form scattered light, which can then enter the third light path channel 610, and then be guided by the third light path channel 610 to the first detection member 321, thereby realizing the light detection function of the reaction unit of the first annular groove 210.

[0066] The fourth light guide 700 has a fourth optical path channel 710, one end of the fourth optical path channel 710 is connected to the second detection member 322, the other end of the fourth optical path channel 710 corresponds to the second annular groove 220 between the second optical path channel 510, and the fourth optical path channel 710 and the optical axis of the outgoing light of the second optical path channel 510 are arranged at a preset angle, so that the light emitted by the second optical path channel 510 is irradiated on the reaction unit of the second annular groove 220 to form scattered light, which can enter the fourth optical path channel 710, and then be guided to the second detection member 322 by the fourth optical path channel 710, so as to realize the light detection function of the reaction unit of the second annular groove 220. By setting the third optical path channel 610 and the fourth optical path channel 710 to be inclined, the scattered light can be better guided, thereby improving the detection accuracy.

[0067] In some embodiments, the preset angle includes 10 degrees to 30 degrees, for example, the preset angle can be 15 degrees, 20 degrees or 25 degrees, etc., without limitation. The scattered light formed by the light irradiating the reaction unit is concentrated in the range of 10 degrees to 30 degrees with the incident light, that is, the scattered light in the range of 10 degrees to 30 degrees is stronger, thereby effectively improving the detection accuracy.

[0068] Furthermore, the third optical path channel 610 gradually shifts upward from an end close to the first optical path channel 410 to an end away from the first optical path channel 410 , and the fourth optical path channel 710 gradually shifts upward from an end close to the second optical path channel 510 to an end away from the second optical path channel 510 .

[0069] During the detection process, reagents and samples need to be added to the reaction unit. When the amount of reagents and samples is large enough, the scattered light formed by the light irradiating the reaction unit can be regarded as a cone with the optical axis of the incident light as the axis. At this time, the third optical path channel 610 and the fourth optical path channel 710 can be located at any position of the conical surface of the cone. When the amount of reagents and samples is small, taking the first optical path channel 410 and the second optical path channel 510 as an example of being parallel to the horizontal plane, the mixed liquid composed of reagents and samples is deposited at the bottom of the reaction unit. At this time, the scattered light formed by the light irradiating the reaction unit will be concentrated above the optical axis of the incident light. The third optical path channel 610 and the fourth optical path channel 710 adopt an upward design, which is suitable for the case of less mixed liquid, and can effectively reduce the use and consumption of reagents and samples, thereby controlling costs.

[0070] Further, the third light guide 600 is provided with a first reference light path channel 620 corresponding to the first light path channel 410, and the fourth light guide 700 is provided with a second reference light path channel 720 corresponding to the second light path channel 510;

[0071] The first reference optical path channel 620 is connected to a first reference detection element (not shown);

[0072] The second reference optical path channel 720 is connected to a second reference detection component (not shown).

[0073] In implementation, the first reference optical path channel 620 can guide the scattered light formed after the first optical path channel 410 is emitted to the reaction unit to the first reference detection element, and the second reference optical path channel 720 can guide the scattered light formed after the second optical path channel 510 is emitted to the reaction unit to the second reference detection element. The reference detection element monitors the life and stability of the light source element, further improving the detection accuracy.

[0074] In some embodiments, the diameter of the first optical path channel 410 gradually decreases from the end close to the first light source 311 to the end away from the first light source 311, and the diameter of the second optical path channel 510 gradually decreases from the end close to the second light source 312 to the end away from the second light source 312. By gradually narrowing the optical path channel, the light is gathered and focused, which can effectively improve the detection accuracy.

[0075] In some possible embodiments, each optical path channel may also be designed to have a gradually decreasing diameter. For example, the diameter of the first optical path channel 410 gradually decreases from the incident end to the exit end, or the diameter of the first optical path channel 410 decreases in sections from the incident end to the exit end.

[0076] In some possible embodiments, at least one first aperture 341 is disposed in the first optical path channel 410 , and at least one second aperture 342 is disposed in the second optical path channel 510 .

[0077] During implementation, the aperture is in the shape of a ring with a hole in the center, which can block stray light at the edge and only allow light from the center to pass through, which can further improve detection accuracy.

[0078] In some possible embodiments, the first light guide member 400 and the third light guide member 600 and / or the second light guide member 500 and the fourth light guide member 700 are integrally formed structures.

[0079] During implementation, the first light guide 400 and the third light guide 600 are an integrated part, and the second light guide 500 and the fourth light guide 700 are an integrated part, which facilitates installation and can also achieve accurate corresponding settings of various optical path channels, thereby improving detection accuracy.

[0080] In some possible embodiments, a first mounting groove 611 and a second mounting groove 612 are provided in the third optical path channel 610, the first mounting groove 611 is used to install the first detection member 321, and the third mounting groove 711 is used to install the first condensing lens;

[0081] A third mounting groove 711 and a fourth mounting groove 712 are provided in the fourth optical path channel 710 . The third mounting groove 711 is used for mounting the second detection member 322 , and the fourth mounting groove 712 is used for mounting the second condensing lens.

[0082] During implementation, the first mounting groove 611, the second mounting groove 612, the third mounting groove 711 and the fourth mounting groove 712 are all groove-shaped, the optical probe part of the first detection component 321 can be embedded in the first mounting groove 611, and the optical probe part of the second detection component 322 can be embedded in the third mounting groove 711, and the first focusing lens and the second focusing lens can play a focusing role, so that the light can be more concentrated on the optical probe of the detection component, thereby improving the detection accuracy.

[0083] In some embodiments, the focusing lens can be a single-sided convex lens or a double-sided convex lens, as long as it can achieve a focusing effect, without limitation.
