Problems solved by technology

[0004] Microfluidic chips are generally ready-to-use and disposable in the field of microbial detection. Every time a test is performed, the chip needs to be replaced manually, and the sample is added manually by centrifugation. When the chip has multiple reaction chambers, it is necessary to repeatedly test the sample Manual sample addition is cumbersome and time-consuming, which affects the progress of microbial detection

Embodiment 1

[0031] This embodiment provides a detection unit 11, such as figure 1 As shown, it includes a rear transfusion tube 13, at least one rear transfusion tube 14, at least one reaction tube 16, at least one front transfusion tube 15, and a front transfusion tube 17. Each reaction tube 16 is used to embed a detection reagent, specifically, to detect Reagent comprises primer and reaction reagent, and the quantity of rear catheter 14, reaction tube 16 and front catheter 15 is the same, and the inner passage of front catheter 15 and the inner channel cross-sectional size of rear catheter 14 are all smaller than reaction tube 16. The cross-sectional size of the inner channel, the rear transfusion tube 13 communicates with the rear end of each reaction tube 16 through each rear transductive tube 14, and the front transfusion tube 17 communicates with the front end of each reaction tube 16 through each preceding transductive tube 15, and the rear transfusion tube 13 Used to communicate w...

Embodiment 2

[0038] This embodiment provides a combination pipe 1, such as figure 2 As shown, it includes a plurality of detection units 11 in Embodiment 1 that are sequentially connected, the rear infusion tube 13 of the detection unit 11 at the rearmost end communicates with the negative pressure device, and the front infusion tube 17 of the detection unit 11 at the front end can be used for It extends into the sample solution to be detected by the sample bottle intelligence; in the two adjacent detection units 11, the rear infusion tube 13 of the detection unit 11 at the front end communicates with the front infusion tube 17 of the detection unit 11 at the rear end. Specifically, the negative pressure device is a vacuum pump. By controlling the opening and closing of the negative pressure device, the sample solution to be tested can be controlled to only enter the reaction tube 16 and not enter the rear catheter 14, ensuring the effect of microbial detection.
