ABSTRACT:
Aspirator and aspirators assemblies, particularly adapted for use by dentists and oral surgeons, include a tubular member having an adaptor tip at one end which is configured to coact with varying sizes of suction hose and/or adaptors whereby the aspirator is readily useable regardless of the type of vacuum utility service provided by the building. The adaptor tip is configured to have a smaller diameter tapered portion to be received in and coupled to a small diameter suction hose, a larger diameter portion at its proximal end dimensioned to be received within and coupled to an intermediate diameter suction hose, and with the larger diameter portion dimensioned to coact with an adaptor dimensioned to be received within and coupled to a large diameter suction hose by means of which the aspirator tip is coupled to such large hose. As an additional feature, the adaptor tip is configured to be received within an elongated convenience handle, with the convenience handle being dimensioned to be received either within the intermediate hose for coupling thereto, or within the adaptor for coupling to a large hose.
