Saliva suction type mouth gag

Abstract

The saliva-suction gag consists of two retractors, a connecting arm, a U-shaped connecting rod, a tongue stop, two silicone tubes and a three-way tube. The two retractors are respectively installed on the buckles of the U-shaped connecting rod. On the retaining button, the opening directions of the two retractors are opposite, the tongue stop is connected to the connecting arm, the positioning blocks at both ends of the connecting arm are installed in the corresponding tracks of the retractor, and one end of the silicone tube is respectively inserted into the ventilation holes on both sides of the tongue stop On the top, the other end of the silicone tube is wound out from the retaining column set at the bottom of the positioning block, and then passes through the C-shaped tube support on the outside of the U-shaped connecting rod, and then inserted into the tee tube. The retractor of the present invention is placed on the lips of both sides of the patient to maintain the opening of the oral cavity and reduce the fatigue caused by the patient's mouth opening. At the same time, the tongue stop can effectively limit the movement of the tongue. The lowest point of the area, so that the saliva in the mouth can be absorbed to the greatest extent, and the moisture can be effectively isolated, creating a relatively dry operating environment for doctors.
