Oral cavity air curtain isolator

Abstract

The invention discloses an oral cavity air curtain isolator. The isolator comprises a mouth gag; an air flow channel is dug in the mouth gag; a pipeline connector is dug in the outer wall of the mouthgag; a hose is connected to the interior of the pipeline connector; the hose communicates with the mouth gag through the pipeline connector; a jet flow seam is dug in the inner wall of the air flow channel; the jet flow seam communicates with the air flow channel; lip bumper concave edges and lip bumper convex edges are evenly distributed on the mouth gag in the circumferential direction; the mouth gag is connected with a main arc-shaped part; the main arc-shaped part comprises a right arc-shaped part and a left arc-shaped part; and the right arc-shaped part and the left arc-shaped part are both arranged in a semi-arc shape. By providing an oral cavity air curtain protection device, a circular air curtain for sealing the oral cavity can be formed, sprayed foam, splashed small liquid drops, fine particles and the like generated in a diagnosis and treatment process are blocked, and the problem of lack of source control of a pollution source in the existing oral cavity diagnosis and treatment process is solved; and the oral cavity air curtain protection device is used in the oral cavity related diagnosis and treatment process, so that the concentration of pollutants in air is reduced, and the risk of cross infection is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to an oral air curtain isolator. Background technique [0002] Most of the consulting rooms are small in size, with many patients, a large flow rate, insufficient ventilation, and turbid air. The aerosols produced by the water guns and dental drills of medical instruments pollute the air and articles in the consulting room. The used instruments and medical waste are sticky with blood, saliva, secretions, etc., which easily pollute the environment of the consulting room. These factors can cause pollution in the limited space of the dental clinic department. Some stomatological hospitals surveyed that the qualified rate of air quality in the dental clinic is only 61.4%. Without the doctor's knowledge, the pollutants sprayed from the oral cavity by patients suffering from respiratory diseases carry a large number of pathogens during oral diagnosis and treatment, and most of them are dispersed in th...

AI Technical Summary

Problems solved by technology

Pollutants attached to surfaces such as protective clothing, such as small droplets carrying pathogens evaporate, and the pathogens still return to the air, becoming a potential hazard

If the protective clothing is not handled properly, doctors still face the risk of infection if they accidentally touch the surface of the contaminated protective clothing
