The hollow cavity 6 is provided with a test strip support sheet 8, the space between the test strip support sheet 8 and the test strip separation blade 7 is a test strip placing area 9, the test tube is internally provided with four test strip placing areas 9, 4 test strips can be placed at most, and 1 to 4 test strips can also be placed according to requirements.

As shown in FIG. 3, the sample processing tube 3 is made of a soft material and can be pinched by hand. Be equipped with sample processing pipe buckle 31 in the sample processing pipe 3, the sample processing pipe 3 lower extreme opening, the opening part is equipped with sample processing intraductal screw thread 32, cooperatees with detection tube top end external screw thread 102.

As shown in fig. 4, a circle of bottom cover protrusions 51 and bottom cover internal threads 52 are arranged in the bottom cover 5, the bottom cover 5 is in threaded connection with the detection tube main body 1, the bottom cover internal threads 52 are matched with the detection tube bottom end external threads 103, and the bottom cover protrusions 51 are tightly attached to the inner wall of the detection tube main body 1, so that the test strip is far away from the inner wall of the detection tube and is in a suspended state.

As shown in fig. 5 and 6, the No. 1 seal stopper 411 is provided on the outer side of the No. 1 seal stopper 41, and engages with the sample processing tube stopper 31 provided on the inner side of the sample processing tube 3. When the No. 1 sealing plug 41 is used, the sample processing pipe 3 is filled with the sample processing liquid in advance, and then the No. 1 sealing plug 41 is placed into the sample processing pipe 3 and is connected in a sealing mode through the buckle. The test strip is taken according to the requirement and is placed into the test tube from the opening at the lower end of the main body 1 of the test tube, the test strip is placed between the test strip retaining sheet 7 and the test strip supporting sheet 8 on the inner wall of the test tube, then the bottom cover 5 is connected to the bottom end of the test tube through the bottom cover internal thread 52 and the detection tube bottom end external thread 103, and the bottom cover bulge 51 is tightly attached to the inner wall of the test tube at the moment.

Therefore, the test strip is uniformly soaked in the liquid from bottom to top, and a tester can observe the color change of the test strip through the transparent shell of the detection tube main body 1 to obtain a detection result.

Example 2

As shown in fig. 8 and 9, a second plug latch 421 is disposed at the through hole on the inner wall of the No. 2 plug 42, and is engaged with the detecting tube latch 101 on the detecting tube main body 1. When the No. 2 sealing plug 42 is used, it is fixed to the detection tube stopper 101 attached to the detection tube main body 1, and the sample processing liquid is poured into the sample processing tube 3 in advance. In this case, the solid sampling rod 2 may be used for sampling, and other sampling devices, such as a nasal swab, an oral swab, etc., may be used for sampling. After the completion sampling, put into the sample treatment who contains the sample treatment liquid with sampling device in the pipe 3, treat that the sample on the sampling device fully releases in the sample treatment liquid back with sample treatment pipe 3 with the test tube connection, solid sampling stick 2 stretches into in the sample treatment pipe 3 this moment, no. 2 sealing plugs 42 play the sealed effect with sample treatment pipe 3 and test tube, can prevent the weeping. The subsequent detection procedure was the same as in example 1.

When using No. 2 sealing plugs, 3 openings of sample processing pipe are great, not only can hold thin sampling stick, sampling spoon to pass through, also can hold other sampling devices such as great sampling swab to pass through. Under different detection scenes, different sampling devices are needed, the number 2 sealing plug is used, so that the application scenes of the invention are greatly increased, one device can simultaneously realize the detection of various samples, great convenience is brought to operators, and the use cost of detection consumables can be reduced.

During the use, can change solid sampling stick 2 into the sampling spoon, be convenient for gather liquid sample.
