To facilitate understanding of a single-use urine extraction tube in this embodiment, the following is further described in connection with two modes of use:
the using mode is as follows: the user sucks a certain amount of sample liquid through the sampling head 1, and the sample liquid flows into the liquid storage tube 3 through the sampling inner cavity 11 for storage. When the sample liquid is required to be detected, the pipe body is pressed, so that the sample liquid in the liquid storage pipe 3 is pressed, flows to the sampling port 12 through the sampling inner cavity 11 and is dripped to the detection equipment.
The second mode of use is: the user unscrews the sampling head 1, collects the sample liquid through the preformed groove part 62 on the sampling rod 6 and puts into the liquid storage tube 3, and the buffer solution is poured into the liquid storage tube 3, and screws the sampling head 1 again, so that the sample liquid and the buffer solution are fully mixed. Then the tube body is pressed, so that the sample liquid in the liquid storage tube 3 flows to the sampling port 12 through the sampling inner cavity 11 under pressure and drops to the detection equipment.
