[0023] This embodiment provides a connected detection column 100, see Figure 1, including a plurality of columns 10 arranged side by side, one end of at least one column 10 being a sample addition end 11, and a reagent layer 20 being arranged in the other end of each column 10; a connecting tube 30 is arranged between two adjacent columns 10, and both ends of the connecting tube 30 are respectively connected to a connecting port 12 arranged on the column 10.

[0024] A plurality of columns 10 are arranged side by side, wherein the plurality of columns 10 are connected by a connecting tube 30. When it is necessary to detect different pathogens on a sample, the sample is added through a sample adding end 11, and the sample can enter each column 10 through the connecting port 12 and the connecting tube 30 to react with each reagent layer 20. The reagent layers 20 in different columns 10 can be used to detect different pathogens. In this way, different pathogens can be detected by adding the sample once, and different reagent layers 20 do not affect each other, thereby improving the detection efficiency and ensuring the detection accuracy.

[0025] Specifically, the number of columns 10 can be determined according to actual needs, such as being set to two, three, etc.

[0026] In the optional solution provided in this embodiment, it is more preferred that the connecting ports 12 on adjacent columns 10 are opposite and at the same height; the connecting tube 30 is configured as a straight tube. Such a configuration can ensure that the sample liquid level in each column 10 is consistent, thereby achieving uniform detection of the sample.

By setting the control layer 22 and the detection layer 21, the detection layer 21 first contacts and reacts with the sample, and by comparing with the control layer 22, the degree of reaction between the detection layer 21 and the sample pathogen can be judged for judgment; the partition 23 is arranged to facilitate demarcation for comparison; specifically, the detection layer 21 and the control layer 22 can use conventional gel detection reagents, which lose color after reacting with pathogens, so that the pathogen status is judged by the degree of discoloration of the detection layer 21.

[0028] In the optional solution provided in this embodiment, it is more preferred that the partition 23 is provided with a through hole that allows the sample to pass through; when there are a lot of samples, they can enter the control layer 22 through the through holes on the partition 23 to continue the reaction.

[0030] In the optional solution provided in this embodiment, it is more preferred that the height of the communication port 12 is higher than the height of the reagent layer 20 , so that the sample can enter from above the reagent layer 20 .

[0031] In the optional solution provided in this embodiment, it is more preferred that the column 10 is set to be made of a transparent material, specifically plastic or glass, to facilitate observation of the reagent layer 20.

[0032] In the optional solution provided in this embodiment, it is more preferred that a reinforcing tube 40 is further provided between adjacent columns 10 to improve the overall strength.

[0033] In the optional scheme provided in this embodiment, it is more preferred that the end of each column 10 facing away from the reagent layer 20 is a sample loading end 11, and the sample can be loaded through any sample loading end 11. At the same time, when the sample liquid level submerges the connecting port 12, the sample flow in multiple columns 10 can still be satisfied.
