Abstract
Due to the low suction strength or an unsuitable positional relationship or distance between the suction feed and the oral cavity, conventional extra-oral intake devices exhibit the problem of not being able to fully suck particulate matter and droplets from teeth, shavings from repair products, saliva, bacteria, blood, rinse water, tooth surface cleaning agents, etc., that are dispersed to outside the oral cavity during practice. In order to improve suction strength, the present invention provides an intake device that is equipped with a protruding airflow-regulating member, the top of which is oriented in the direction in which the fluid flows into the opening part of the suction feed, and that can efficiently suck dispersed particulate matter and droplets within a wide range.
