In order to achieve the above object, the technical scheme of the present utility model is as follows:

the mouth gag comprises a biting part for supporting teeth and a tongue pressing part for pressing a tongue, wherein an operation space for observing and allowing the pharyngeal swab to pass through is formed in the biting part, the biting part comprises a left support frame and a right support frame which are in a V shape, the left support frame and the right support frame are connected into a whole at the top end of the V shape through an upper support bar and a lower support bar, the operation space is formed between the left support frame and the right support frame, and the tongue pressing part is transversely arranged between the left support frame and the right support frame.

The utility model is characterized in that: the solid part of the mouth gag is moved to two sides from the middle, the solid part of the mouth gag is formed by a left support frame and a right support frame, and an operation space is formed between the left support frame and the right support frame, so that self-help sampling personnel can observe and operate through a mobile phone camera or a mirror conveniently. Inside the oral cavity of the sampled person, only the left support frame and the right support frame exist, and no physical part blocks the sight in the middle of the oral cavity, so that the self-help sampling person can easily see the pharyngeal tonsils and the pharyngeal rear walls of the sampled person, such as the self-help sampling person or the child.

As an improvement, the outer walls of the left support frame and the right support frame are provided with anti-skid patterns. The anti-slip patterns help prevent the left and right brackets from slipping after the teeth bite into the left and right brackets.

As a further improvement, the left support frame and the right support frame are arranged in a splayed shape, and the left support frame and the right support frame are connected to the top end of the splayed shape. The left support frame and the right support frame open towards the two sides more towards the deep oral cavity, so that the sight blocking of self-help sampling personnel can be further reduced. Meanwhile, because the cheeks at the two sides are relatively insensitive, the probability of vomit feeling of the person to be picked can be reduced.

As an improvement, the tongue depressor comprises 2 tongue depressors which are respectively and vertically symmetrically arranged between the left support frame and the right support frame. Because the shape of the tongue depressor in the application is different from other tongue depressors in the prior art, once the tongue depressors are positioned on the upper layer, the tongue depressors cannot function. The tongue pressing parts are arranged up and down, so that the user can not pay attention to whether the tongue pressing parts are positioned on the lower layer or not.

As an improvement, the tongue depressor is in a shape of a straight line or a T. The T-shaped tongue pressing part can also prevent adverse effect of upward tilting of the tongue tip on observation.

As a further development, the tongue depressor has a projection facing the operating space. The throat swab is generally in a suspended state when in use, and the protruding part of the tongue pressing part can provide support for the throat swab, so that the throat swab is beneficial to completing sampling actions by self-help personnel with relatively saving effort.

In conclusion, the self-help sampling device disclosed by the utility model is not only beneficial to reducing the blocking of the mouth gag on the sight of self-help sampling personnel, and is beneficial to improving the sampling efficiency, but also has the advantages of simple structure and low production cost.
