Saliva ejector
First Claim
1. A device for removing suction fluids and solids by from a mouth and oral cavity area during dental-medical treatments, the device comprising:
- a tube segment, a first end of which being charged with a low air pressure, the tube segment further including a second end; and
a sleeve shaped ejector tip having at least one suction opening on a peripheral side thereof, the ejector tip being attached to the second end of the tube segment so that in a first suctioning position, a first longitudinal segment of the ejector tip overlaps with the second end of the tube segment in an axial direction and with a second longitudinal segment extending beyond the second end of the tube segment, wherein, for changing to a second suctioning position, the ejector tip is axially or spirally slidable on the tube segment, and wherein, in the second suctioning position, the second longitudinal segment of the ejector tip overlaps with the second end of the tube segment, and only an upper front opening on the second end of the tube segment functions as a suction opening.

Abstract
A device for removing fluids and solid substances by suction from the mouth and oral cavity area during dental-medical treatments is provided. The device includes a first tube segment, a first end of which can be charged with low air pressure, and to the second end of which a sleeve-like ejector tip is attached. By a relative movement of the ejector tip on the tube segment, the ejector tip can be alternated between a first suctioning position and a second suctioning position. In the second suctioning position, only the opening on the upper front side of the second end of the tube segment functions as a suction opening to allow point-focused suctioning with high suction force. In contrast thereto, in the first suctioning position, a plurality of additional suction openings is provided around the circumference to remove fluids from the mouth and oral cavity area by suction. Thus, it is possible to alternate between both suctioning positions without having to disassemble the saliva ejector.

15. A device for removing fluids and solids by suction from a mouth and oral cavity area during dental-medical treatments, the device comprising:
-
a tube segment, a first end of which being charged with low air pressure, the tube segment further including a second end; and
a sleeve shaped ejector tip having at least one suction opening, the second end of the tube segment being provided with, on a circumferential side thereof, at least one suction opening, an end of the ejector tip being open and movable on the second end of the tube segment, wherein, on the basis of an execution of a relative movement on the tube section, the ejector tip can be changed from a first suctioning position with overlapping suction openings to a second suctioning position with suction openings that do not overlap. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 26)

27. A saliva ejector comprising:
-
an ejector tip being movably attached to an end of a tube segment, the ejector tip being moveable between a first suction position and a second suction position, the ejector tip including suction openings formed on a circumferential side of the ejector tip and including at least one direct suction opening formed in a plane that is substantially perpendicular to a longitudinal axis of the tube segment, wherein, in the first suction position, the suction openings formed on the circumferential side of the ejector tip facilitate suctioning of saliva, and wherein, in the second suction position, only the direct suction opening facilitates suctioning of saliva. - View Dependent Claims (28)
