Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2:
The outer surface of a kind of novel big buccal swab, including holding rod 1, holding rod 1 is equipped with anti-skid chequer, passes through the hand of setting
The stabilization that bar 1 facilitates swab is held, one end of holding rod 1 is equipped with antipriming pipe 13, and antipriming pipe 13 can guarantee 14 energy of rubber nipple
Sample is enough sucked, the outer surface of antipriming pipe 13 is arranged with rubber nipple 14, and rubber nipple 14 is made of natural rubber, latex rubber
