Abstract
A disposable saliva ejector has a strainer tip at its distal end. The strainer tip has a plurality of slots through which saliva, blood etc. can be extracted from the patient's mouth. A protective flange is located adjacent the strainer tip, extends parallel to it, and is spaced apart from it. The space between the flange and the tip is sufficiently small that the patient's flesh is unlikely to become interposed between the tip and the flange. For this reason, slots in the region of the flange will likely always remain unblocked. For this reason, the tip and flange do not become tightly wedged against the patient's flesh as a result of the vacuum supplied to the ejector.
