Abstract

The invention discloses an auxiliary extending instrument for the oral medicine. The auxiliary extending instrument for the oral medicine comprises a pipe body, wherein a drive box is fixedly connected to one end of the pipe body; two extruding mechanisms are slidably arranged in the drive box in a sealing way; the pipe body and the drive body are rotatably provided with one same rotary shaft in apenetrating way; an inserting rod clamped with the rotary shaft is slidably arranged at the upper end of the drive box in an inserting way; a liquid storage pipe is fixedly arranged in the pipe bodyand communicates with the drive box through a first air guide pipe; a first piston plate is slidably arranged in the liquid storage pipe in a sealing way; multiple elastic mechanisms are fixedly connected between the left end side wall of the first piston plate and the inner wall of the liquid storage pipe; a clapboard is fixedly arranged in the liquid storage pipe on the right side of the first piston plate; an air guide hole is formed in the upper end of the clapboard; the rotary shaft rotatably penetrates through the liquid storage pipe, the first piston plate and the clapboard; and medicine feeding holes communicating with each other are formed in the liquid storage pipe on the right side of the clapboard and the pipe body. The auxiliary extending instrument for the oral medicine provided by the invention not only is convenient to clean and dose a focus part of an oral cavity, but also can be used for stirring and mixing medicine liquid.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary extension device for stomatology.
