Abstract

The invention provides a negative-pressure mouth gag capable of preventing aerosol diffusion in the stomatology department, and relates to the technical field of oral medical instruments. The negative-pressure mouth gag comprises a mouth gag body and a transparent mouth covering box, wherein the mouth gag body comprises lip supports used for opening lips and a saliva suction cover attached to thewall of an oral cavity; suction holes are densely distributed on the inner surfaces of the mouth covering box and the saliva suction cover and communicate with a first negative-pressure generating unit; the mouth covering box comprises a mouth covering part connected with the peripheries of the lips in a sealed and covering mode and an operation box fixedly arranged the mouth covering part; supporting columns are connected with and arranged on the operation box in a pivoted mode; a flexible operation opening is arranged on the operation box in a sealed mode; a magnifying lens is embedded at one side of the flexible operation opening; and a hand rest frame is arranged in the operation box. The negative-pressure mouth gag provided by the invention solves the problem of aerosol diffusion in the oral cavity treatment process in the prior art.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to a negative pressure mouthpiece for preventing aerosol spreading in the department of stomatology. Background technique [0002] There are many diseases that can be transmitted through aerosols or aerosols, such as new coronary pneumonia, atypical pneumonia, influenza, tuberculosis, measles, etc. The secretions and aerosols discharged by infected people through coughing, sneezing, etc. will The virus is transmitted to people around, and aerosol-borne diseases spread quickly and are extremely harmful. During the clinical operation of the department of stomatology, a large amount of aerosols and aerosols will be produced during the use of high-speed turbine handpieces, ultrasonic tooth cleaners and other equipment, so during the epidemic of certain infectious diseases, the department of stomatology or dental clinics become a disease A popular high-risk location tha...
