Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Refer to fig. 1 and show, for the utility model provides an anti-pollution nasopharynx swab, including pharynx swab body 1, pharynx swab body 1 is equipped with protective sleeve 2 outward, and protective sleeve 2's one end is provided with and seals membrane 23, seals membrane 23 and supports with pharynx swab body 1's sampling front end 11, and protective sleeve 2's the other end is provided with finger separation blade 21. Two fingers are used for propping against the finger blocking sheet 21, so that the sampling front end 11 of the throat swab body 1 can conveniently break through the sealing film 23 for sampling. The anti-pollution nasopharyngeal swab of the utility model can prevent the sampling front end of the nasopharyngeal swab body 1 from contacting with the secretion and soft tissue in the nasal cavity by arranging the protective sleeve 2, thus solving the problem of sampling pollution; meanwhile, the stimulation of the rough throat swab to the nasal cavity of the person to be sampled is avoided, and the discomfort is relieved.
Specifically, the protective sleeve 2 is further provided with a sealing element 22 at one end of the finger baffle 21, the throat swab body 1 penetrates through the sealing element 22, the sealing element 22 can enable the sampling front end 11 to be stored in a sealed space before being used, the cleanness of the sampling front end 11 is guaranteed, and in addition, the throat swab body 1 penetrates through the sealing element 22 to play a limiting role and prevent the throat swab body 11 from shaking.
