[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] When performing sample analysis, first place the reaction vessel in the incubation and detection device, then add the sample to be analyzed and the reagent into the reaction vessel, and finally transmit detection signals, such as optical signals, to the position of the reaction vessel through the detection cable to detect the sample in the reaction vessel. In the traditional solution, the detection cable is randomly arranged on both sides of the incubation and detection device according to the position of the sample detection position and extends to the sample detection position of the incubation and detection device. Therefore, spaces for arranging the detection cable need to be reserved on both sides of the incubation and detection device, making the volume occupied by the incubation and detection device relatively large, which is not conducive to the overall layout of the sample analyzer. Based on the problems of the traditional solution, this application provides an incubation and detection device and a sample analyzer to solve the problems of the traditional solution, as detailed below.

[0035] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an incubation and detection device provided by an embodiment of this application. As Figure 1 shown, the incubation and detection device 10 includes a sample assembly 11 and multiple detection cables 12.

[0036] The sample assembly 11 includes at least two sample detection seats 110. Each sample detection seat 110 is provided with multiple sample detection positions 111. The sample detection seat 110 is provided with a receiving groove 112 at each sample detection position 111 for placing the reaction vessel 100 to be detected.

[0037] The multiple detection cables 12 are arranged on one side of the sample assembly 11. The multiple detection cables 12 correspond to the multiple sample detection positions 111 one by one and extend from one side of the sample assembly 11 to each sample detection position 111 respectively. The detection cable 12 is used to transmit detection signals to the sample detection position 111 to detect the sample in the reaction vessel 100.

[0038] Therefore, in this embodiment, since the multiple detection cables 12 are all arranged on one side of the sample assembly 11, the incubation and detection device 10 only needs to reserve the occupied space of the detection cable 12 on one side of the sample assembly 11, reducing the occupied space of the incubation and detection device 10, which is thus conducive to the overall layout of the sample analyzer.

[0039] The sample detection positions 111 of adjacent sample detection seats 110 are arranged in a staggered manner, and, in the direction in which the detection cable 12 extends, the detection cables 12 corresponding to the sample detection positions 111 of the front and rear two sample detection seats 110 are alternately arranged.

[0040] For example, as Figure 1As shown, the sample component 11 includes two sample detection seats 1101 and 1102. In the extending direction of the detection cable 12, the two sample detection seats 1101 and 1102 are arranged front and back, with the sample detection seat 1101 in front of the sample detection seat 1102. A plurality of sample detection positions 1110 and 1111 are respectively arranged on the two sample detection seats 1101 and 1102. Each sample detection position 1110 is correspondingly connected to a detection cable 121. Similarly, each sample detection position 1111 is correspondingly connected to a detection cable 122. Since the sample detection positions 1110 on the sample detection seat 1101 and the sample detection positions 1111 on the sample detection seat 1102 are arranged in a staggered manner, and the plurality of sample detection positions 1110 on the sample detection seat 1101 are arranged at intervals. In order to reasonably layout the detection cable 12, the detection cables 121 corresponding to the sample detection positions 1110 and the detection cables 122 corresponding to the sample detection positions 1111 are arranged alternately. So that the detection cable 122 can pass through between two adjacent sample detection positions 1110 to reach the sample detection position 1111. It can avoid the detour of the detection cable 122, save the cost of the detection cable 122, and enable the detection cables 12 corresponding to the front and back sample detection positions 111 to be uniformly and neatly arranged on one side of the sample component 11. It should be understood that when the number of sample detection seats 110 is three or more, the setting method is similar and will not be elaborated here. Thus, the structure of the incubation detection device can be made more compact, with a smaller volume and a more reasonable layout.

[0041] Please refer to Figure 2 , Figure 2 is Figure 1 a partial structural schematic diagram of the incubation detection device shown. As Figure 1 and 2 shown, the incubation detection device 10 further includes at least two circuit boards 13. The circuit boards 13 correspond to the sample detection seats 110 one by one, that is, at least two circuit boards 13 are respectively arranged on the sides of at least two sample detection seats 110. A plurality of wire grooves 131 are arranged on the circuit board 13. In the extending direction of the detection cable 12, the detection cable 12 corresponding to the sample detection seat 110 at the rear passes through the wire groove 131 of the circuit board 13 of the sample detection seat 110 at the front. The size of the wire groove 131 can be comparable to the size of the gap between the sample detection positions 111. By arranging the wire groove 131 on the circuit board 13, it is convenient for the detection cable 12 to extend to the sample detection position 111 of the sample detection seat 110 at the rear, facilitating the wiring of the detection cable 12.

[0042] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 1 a disassembled structural schematic diagram of one of the sample detection positions in the incubation detection device shown, Figure 4 is Figure 1Schematic structural diagram of the clamping member of the incubation detection device shown. The incubation detection device 10 further includes a clamping member 14, a fixing post 15, and an elastic pressing member 16. Among them, the clamping member 14 is clamped to the notch 1120 of the accommodating groove 112, and two fixing holes 141 are provided on the clamping member 14. There are two fixing posts 15, which are respectively passed through the two fixing holes 141. The elastic pressing member 16 is arranged between the two fixing posts 15 and is in a compressed state under the limitation of the two fixing posts 15, and then bends towards the middle of the accommodating groove 112 to press the reaction vessel 100 in the accommodating groove 112. Specifically, the sample detection seat 110 forms a step surface 113 in the accommodating groove 112. The clamping member 14 includes a main body portion 142 and an extension portion 143 extending from a part of the main body portion 142, so that the extension portion 143 forms a notch 144, and the two fixing posts 15 are arranged at both ends of the notch 144. When the clamping member 14 is clamped to the notch 1120, the extension portion 143 abuts against the step surface 113. The elastic pressing member 16 is arranged in the notch 144 and is limited by the two fixing posts 15 to be in a compressed state. In an optional embodiment, the elastic pressing member 16 can be a spring structure, which is compressed and deformed under the limitation of the two fixing posts 15, and then bends towards the middle of the accommodating groove 112 to press the reaction vessel 100 from the side, ensuring that the reaction vessel 100 is fixed in the accommodating groove 112 without shaking phenomenon.

[0043] Please refer further to Figure 1 and Figure 3 , a first cutting surface structure 145 is provided on the clamping member 14, and a second cutting surface structure 114 is provided on the sample detection seat 110. When the clamping member 14 is clamped to the notch 1120 of the sample detection seat 110, the first cutting surface structure 145 and the second cutting surface structure 114 abut against each other to limit the relative movement between the clamping member 14 and the sample detection seat 110.

[0044] Among them, the first cutting surface structure 145 can be arranged on the side of the clamping member 14 away from the notch 144 and extends from the main body portion 142 to the extension portion 143.

[0045] Please refer again to Figure 1 and Figure 2 , the incubation detection device 10 further includes a light source assembly 17, a lens barrel 18, a lens (not shown in the figure), and a photosensitive chip 200. Among them, the light source assembly 17 includes a plurality of light sources (not shown in the figure), and each light source emits light of a certain wavelength. The plurality of light sources are arranged in an array. For example, if there are 4 light sources, they can be arranged in a square shape. If there are 6 or 8 light sources, they can form two rows with the same number in each row.

[0046] One end of the detection cable 12 is connected to the light source assembly 17 and is used to transmit the light emitted by the light source in the light source assembly 17. The lens barrel 18 and the lens are arranged between the other end of the detection cable 12 and the reaction vessel 100 and are used to focus the light transmitted by the detection cable 12 so as to transmit it into the reaction vessel 100.

[0047] The photosensitive chip 200 is arranged on one side of the reaction vessel 100 away from the lens barrel 18 and the lens. The photosensitive chip 200 is used to receive the light that has passed through the reaction vessel 100. Since the light transmitted by the detection cable 12 will be lost after passing through the sample in the reaction vessel 100 and different components in the sample have different absorption rates for light of different wavelengths, the components of the sample in the reaction vessel 100 can be analyzed by receiving the light that has passed through the reaction vessel 100 through the photosensitive chip 200. The photosensitive chip 200 is arranged on the circuit board 13, thus saving the carrier for carrying the photosensitive chip 200.

[0048] The incubation detection device 10 further includes a base 300, a heating element 400, a temperature sensor 500 and a collection board 600. Among them, the base 300 is used to carry the sample detection seat 110. Specifically, the base 300 includes a first base 301 and a second base 302. The first base 301 and the second base 302 are arranged at intervals, and when the incubation detection device 10 is placed upright, as Figure 1 shown in the state, the first base 301 is located above the second base 302. The first base 301 is used to carry the sample detection seat 110, and the second base 302 is used to carry the light source assembly 17.

[0049] The heating element 400 is arranged between the sample detection seat 110 and the base 300, specifically between the sample detection seat 110 and the first base 301. The heating element 400 is used to heat the reaction vessel 100 in the sample detection seat 110 so as to incubate the sample in the reaction vessel 100. The temperature sensor 500 is used to detect the temperature of the reaction vessel 100, that is, to detect whether the temperature of the reaction vessel 100 after being heated by the heating element 400 is within the normal range, so as to improve the accuracy of incubation. The collection board 600 is used to collect the detection data of the incubation detection device 10. The detection data includes but is not limited to the temperature data of the temperature sensor 500 and the intensity data of the light received by the photosensitive chip 200. It is possible to judge whether the temperature is within the normal range according to the temperature data and judge the components of the sample in the reaction vessel 100 according to the intensity data of the light.

[0050] The embodiment of the present application also provides a sample analyzer, and the sample analyzer includes the incubation detection device described above.

[0051] The embodiments of the present application further provide an incubation detection device and a sample analyzer. The incubation detection device includes: a sample assembly, including at least two sample detection seats, each of the sample detection seats is provided with a plurality of sample detection positions, and each of the sample detection seats is provided with a receiving groove at each of the sample detection positions for placing a reaction container to be detected; a plurality of detection cables, arranged on one side of the sample assembly, the plurality of detection cables correspond to the plurality of sample detection positions one by one, and extend from one side of the sample assembly to each of the sample detection positions respectively, and the detection cables are used for transmitting detection signals. Since the plurality of detection cables are all arranged on one side of the sample assembly, the incubation detection device only needs to reserve the occupied space of the detection cables on one side of the sample assembly, reducing the occupied space of the incubation detection device, thereby being beneficial to the overall layout of the sample analyzer.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
