Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As the sampling tube structure 100 commonly used in the prior art shown in FIG. 1A, since the cotton stalk 202 of the sampling swab 20 shown in FIG. 1B is easy to carry viruses and is at risk of infection, the inner diameter of the inner cavity of the sampling tube structure 100 containing the protective solution in the prior art is wider, which is beneficial to the collection and disposal of the sampling swab 20, and the sampling swab 20 is soaked by a large volume, at least 10 ml of protective solution is usually used, such design is unreasonable, not only the protective solution is wasted, but also the collected sample is seriously diluted, so that the concentration of the sample is too low, and the later detection is inaccurate.

In the embodiment of the present invention, as shown in fig. 2A to 3, a needle type sampling tube 10 includes a body 1, an integrally formed needle type inner cavity 2 is provided in the body 1, the needle type inner cavity 2 includes an upper inner cavity section 21 and a lower inner cavity section 22 which are vertically communicated; the inner cavity upper section 21 is of a slightly trumpet-shaped structure, and the inner diameter of the inner cavity upper section 21 is gradually reduced from the opening end 23 to the inner cavity lower section 22; the height of the inner cavity upper section 21 is far less than that of the inner cavity lower section 22, wherein the inner diameter of the end of the inner cavity upper section 21 and the inner diameter of the inner cavity lower section 22 are slightly larger than or equal to the outer diameter of the cotton ball 201 at the front end of the sampling cotton swab 20.

In the embodiment of the utility model, the upper section 21 of the inner cavity is designed to be a slightly trumpet-shaped structure, so that the cotton swab 20 for sampling can be smoothly inserted into the needle-type inner cavity 2 with smaller inner diameter, and the sample pollution caused by misoperation is avoided; meanwhile, the height of the upper section 21 of the inner cavity is far lower than that of the lower section 21 of the inner cavity, so that the situation that the cotton stalk 202 of the sampling cotton swab 20 can be submerged by using too much protective liquid due to the overlarge volume of the upper section 21 of the inner cavity can be avoided, and the concentration of the sample can be diluted by too much protective liquid; that is, in the embodiment of the present invention, the inner diameter of the needle-type inner cavity 2 may be only at the open end 23 and may be significantly larger than the outer diameter of the cotton ball 201, and the rest may be slightly larger than or equal to the outer diameter of the cotton ball 201.
