16. The apparatus according to claim 15, wherein the stopper is a filter disposed at a side of the opening of the self-sealing cover facing the bottom of the tube;

or the stop piece is a convex rib which is arranged around the opening of the self-sealing cover body and extends towards the bottom of the tube body.

17. The sample testing device according to claim 14, wherein said self-sealing cover is an elastic body and is provided with a self-sealing cut;

or, the self-sealing cover body comprises a main body part, an elastic part and a piston, wherein the main body part forms a channel for communicating with the tube body, the piston seals the channel under the elastic support of the elastic part in a natural state, and when the internal pressure of the tube body is increased, the piston overcomes the elastic support of the elastic part to open the channel.

18. The sample testing device of any one of claims 1 to 17, further comprising:

the information acquisition unit is used for acquiring personal information of the testee;

the processing unit is used for recording the position information of the sample tube storing the tested sample, which is placed in the sample tube storing unit;

the processing unit is further used for recording binding information after the personal information is associated with the position information.
