口腔用筛网

Screen for mouth

Abstract

一种口腔用筛网,包括柱状的能贴在口腔内环周面的筛网罩,该筛网罩中设置有口腔通气的圆柱通槽,该圆柱通槽内壁设置斜条,该斜条能够在通过的气体过去的时候起到阻止外界有毒颗粒物质的袭扰。所述的斜条均匀分布。有效地避免了还没有任何装置来防止口腔手术中所受到的外界有毒颗粒物质的袭扰的缺陷。
The utility model relates to a screen for a mouth. The screen comprises a cylindrical screen cover which can be attached onto the inner annular circumferential surface, wherein the screen cover is provided with a cylindrical through groove for ventilating the mouth, the inner wall of the cylindrical through groove is provided with slanted bars, and the harassing attack of external toxic particles can be prevented by the slanted bars when the air is ventilated. The slanted bars are uniformly distributed. By adopting the screen for the mouth, the weakness that no device for preventing the harassing attack of the external toxic particles in the oral surgery is provided can be effectively avoided.
