Description

External suction mask

Technical Field

The utility model relates to an oral surgery appurtenance field specifically indicates an extraoral suction face guard.

Background

In the oral cavity diagnosis and treatment operation, as turbine power, an ultrasonic agitation device or cauterization equipment is needed, a large amount of aerosol, spray mixed with blood and saliva, powder and smoke generated by grinding tooth bodies and repair materials can be generated, infection risks can be caused to medical staff operating beside a chair and other doctors and patients in a consulting room, and the surfaces of surrounding objects and indoor air can be polluted. The existing saliva sucking tube can only suck saliva in the mouth, and has weak sucking effect on pollutants splashed and dispersed outside the mouth. The single dental diagnosis and treatment suction device has strong suction effect, but is a single device which is independently supplied with power, so the device has large volume, large noise during operation, too strong attraction, easy suction of objects such as treatment towels, small dental instruments and the like, and meanwhile, the device needs to be cleaned and disinfected regularly because of the single suction device, otherwise, secondary pollution or disease transmission is easy to cause. So that the use cost is high and the use scene is limited. Therefore, a more convenient and efficient device is needed to reduce the risk of contamination and disease transmission caused by aerosol dispersion during oral diagnosis and treatment.
