Patent attributes
A suction handpiece for a dental treatment unit has a negative pressure connection which can be connected with a negative pressure source of the treatment unit. A saliva connection of the suction unit can be connected with a saliva suction cannula and an atomized spray connection that can be connected with an atomized spray suction cannula. A branched flow path connects the negative pressure connection with both the saliva connection and the atomized spray connection and includes a branching section on which a negative pressure channel ending on the negative pressure connection divides into a saliva channel ending on the saliva connection and an atomized spray channel ending on the atomized spray connection. The atomized spray channel at its narrowest point has a first cross sectional area which is at least twice as large as a second cross sectional area at the narrowest point of the saliva channel.
