Similarly, the incident end of the seventh optical path channel 561 is connected to the second light source 320, so that the light emitted by the second light source 320 passes through the seventh optical path channel 561, the fourth reflector 504, the third optical path channel 521, the second reflector 502, and the fourth optical path channel 522 in sequence and is emitted to the reaction unit of the second annular groove 220.

[0110] In some embodiments, the first light guide 510 and the fifth light guide 550 can be an integrated structure, and the second light guide 520 and the sixth light guide 560 can also be an integrated structure, which has a simple structure, is easy to install, and can effectively improve the structural strength of the light guide.

[0111] Since the incident end of the fifth optical path channel 551 extends in a direction away from the center point of the carrier 200, and the incident end of the seventh optical path channel 561 extends in a direction close to the center point of the carrier 200, the distance between the first light source 310 and the second light source 320 becomes larger, thereby reducing interference caused by the close distance between the light sources and improving the accuracy of light detection.

[0112] Further, the first light guide assembly further includes a seventh light guide member 570 and an eighth light guide member 580;

[0113] The seventh light guide 570 is disposed on the periphery of the first annular groove 210 , and the eighth light guide 580 is disposed on the inner periphery of the second annular groove 220 ;

[0114] The seventh light guide 570 has a ninth light path channel 571 corresponding to the second light path channel 512 and connected to the first detection element 410, and the ninth light path channel 571 is arranged at a preset angle with the optical axis of the outgoing light of the second light path channel 512;

[0115] The eighth light guide 580 has a tenth light path 581 corresponding to the fourth light path 522 and connected to the second detection element 420 . The tenth light path 581 is arranged at a preset angle with the optical axis of the outgoing light of the fourth light path 522 .

[0116] When implementing, Figure 2 As shown, the fixed disk 100 is composed of a disk plane 110, a disk outer annular surface 120, and a disk inner annular surface 130, which together form an annular inner space, and the first annular groove 210 and the second annular groove 220 can be accommodated in the inner space and rotate along the annular inner space. The first light guide 510, the second light guide 520, the third light guide 530 and the fourth light guide 540 are arranged on the disk plane 110 and at least partially located in the accommodation space, the seventh light guide 570 is installed on the disk outer annular surface 120, that is, the seventh light guide 570 is located at the periphery of the first annular groove 210, and the eighth light guide 580 is installed on the disk inner annular surface 130, that is, the eighth light guide 580 is located at the inner periphery of the second annular groove 220.

[0117] The fifth light guide member 550 has a ninth light path channel 571 therein, one end of the ninth light path channel 571 is connected to the first detection member 410, the other end of the ninth light path channel 571 corresponds to the first annular groove 210 spaced between the second light path channel 512, and the ninth light path channel 571 and the optical axis of the outgoing light of the second light path channel 512 are arranged at a preset angle, so that the light emitted by the second light path channel 512 is irradiated on the reaction unit of the first annular groove 210 to form scattered light, which can then enter the ninth light path channel 571, and then be guided by the ninth light path channel 571 to the first detection member 410, thereby realizing the scattered light detection function of the reaction unit of the first annular groove 210.

[0118] The eighth light guide 580 has a tenth optical path channel 581, one end of the tenth optical path channel 581 is connected to the second detection element 420, the other end of the tenth optical path channel 581 corresponds to the second annular groove 220 between the fourth optical path channel 522, and the optical axes of the outgoing light of the tenth optical path channel 581 and the fourth optical path channel 522 are arranged at a preset angle, so that the light emitted by the fourth optical path channel 522 is irradiated on the reaction unit of the second annular groove 220 to form scattered light, which can enter the tenth optical path channel 581, and then be guided to the second detection element 420 by the tenth optical path channel 581, so as to realize the scattered light detection function of the reaction unit of the second annular groove 220. By setting the ninth optical path channel 571 and the tenth optical path channel 581 to be inclined, the scattered light can be better guided, thereby improving the detection accuracy.

[0119] 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.

[0120] Furthermore, the ninth optical path channel 571 gradually shifts upward from an end close to the second optical path channel 512 to an end away from the second optical path channel 512 , and the tenth optical path channel 581 gradually shifts upward from an end close to the fourth optical path channel 522 to an end away from the fourth optical path channel 522 .

[0121] During the detection process, reagents and samples need to be added to the reaction unit. When the amount of reagents and samples is sufficient, 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 ninth optical path channel 571 and the tenth optical path channel 581 can be located at any position of the conical surface of the cone. When the amount of reagents and samples is small, taking the second optical path channel 512 and the fourth optical path channel 522 being parallel to the horizontal plane as an example, 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 ninth optical path channel 571 and the tenth optical path channel 581 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.

[0122] Furthermore, at least one first aperture 610 is disposed in the first optical path channel 511 and / or the fifth optical path channel 551 , and at least one second aperture 620 is disposed in the third optical path channel 521 and / or the seventh optical path channel 561 .

[0123] 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.

[0124] In some embodiments, the third light guide 530 has an eleventh light path channel 531 , a twelfth light path channel 532 and a fifth reflective member 505 ;

[0125] The fourth light guide member 540 has a thirteenth light path channel 541, a fourteenth light path channel 542 and a sixth reflective member 506;

[0126] The eleventh optical path channel 531 corresponds to the third light source 330 , and the thirteenth optical path channel 541 corresponds to the fourth light source 340 ;

[0127] The fifth reflector 505 is disposed between the eleventh optical path channel 531 and the twelfth optical path channel 532, and is used to reflect the light incident into the eleventh optical path channel 531 to the twelfth optical path channel 532 and then to the reaction unit of the first annular groove 210 to form a transmitted light, so as to be received by the third detection element 430;

[0128] The sixth reflector 506 is disposed between the thirteenth optical path channel 541 and the fourteenth optical path channel 542 for reflecting the light incident into the thirteenth optical path channel 541 to the fourteenth optical path channel 542 and then emitting to the reaction unit of the second annular groove 220 to form a transmitted light to be received by the fourth detection element 440 .

[0129] During implementation, the third light guide 530 can refer to the above-mentioned first light guide 510, and the fourth light guide 540 can refer to the above-mentioned second light guide 520. The light from the light source can be emitted to the reaction unit of the first ring groove 210 or the second ring groove 220 after one reflection. The difference lies in that the first light guide 510 and the second light guide 520 respectively guide the light to the reaction unit of the first ring groove 210 or the second ring groove 220 to form scattered light, while the third light guide 530 and the fourth light guide 540 respectively guide the light to the reaction unit of the first ring groove 210 or the second ring groove 220 to form transmitted light. By integrating two light detection functions, the detection accuracy is further guaranteed.

[0130] In some optional embodiments, the second light guide assembly further includes a ninth light guide member 590 and a tenth light guide member 600;

[0131] The ninth light guide 590 is disposed on the periphery of the first annular groove 210 , and the tenth light guide 600 is disposed on the inner periphery of the second annular groove 220 ;

[0132] The ninth light guide 590 has a first accommodating cavity 591 and a fifteenth optical path channel 592 connected to the first accommodating cavity 591. The first accommodating cavity 591 is used to accommodate and install the third detection element 430. The fifteenth optical path channel 592 corresponds to the twelfth optical path channel 532.

[0133] The tenth light guide member 600 has a second accommodating cavity and a sixteenth light path channel 602 connected 601 to the second accommodating cavity. The second accommodating cavity is used to accommodate and install the fourth detection member 440 . The sixteenth light path channel 602 corresponds to the fourteenth light path channel 542 .

[0134] During implementation, the ninth light guide 590 and the tenth light guide 600 are both hollow cavity structures, wherein the third detection member 430 is built into the first accommodating cavity 591 of the ninth light guide 590, the first accommodating cavity 591 is connected to the fifteenth optical path channel 592, and the transmitted light formed by the reaction unit emitted from the twelfth optical path channel 532 to the first annular groove 210 will be received by the fifteenth optical path channel 592, and the fifteenth optical path channel 592 will transmit the transmitted light to the third detection member 430. Similarly, the fourth detection member 440 is built into the second accommodating cavity of the tenth light guide 600, the second accommodating cavity is connected to the sixteenth optical path channel 602, and the transmitted light formed by the fourteenth optical path channel 542 emitted to the reaction unit of the second annular groove 220 will be received by the sixteenth optical path channel 602, and the sixteenth optical path channel 602 will transmit the transmitted light to the fourth detection member 440, thereby realizing the transmitted light detection function of the reaction units of the first annular groove 210 and the second annular groove 220.

[0137] In some embodiments, the detection device of the present application includes a base, a fixed plate 100, a driving member, a carrier plate 200 and a detection module.
