Abstract
A dental strainer unit includes a plastic strainer, a plastic strainer cap, and a transparent, non-rigid plastic housing. The strainer unit can be cost-effectively manufactured and easily disassembled and cleaned. The strainer cap can be manufactured in a variety of sizes to permit different aspirator devices to be attached thereto, and the housing can be snap-fit over the enlarged head of a saliva ejector valve. The dental strainer unit can be used in a modularized dental aspiration system.
Claims10
A dental strainer unit for use with an aspirator, comprising:
- a plastic strainer having an open inlet end and an outlet end, the outlet end having a multiplicity of openings sized to permit saliva, blood and water to pass out of the strainer and to retain solids within the strainer;
- a plastic strainer cap attached to the strainer and covering the inlet end thereof, the cap having an inlet port where an aspirator device can be attached;
- and
- a transparent, non-rigid plastic housing having an inlet end and an outlet end, the inlet end being shaped to receive the strainer and strainer cap so that the inlet end of the strainer faces the inlet end of the housing, the outlet end of the strainer faces the outlet end of the housing, and the strainer and strainer cap are removably secured within the housing, the outlet end of the housing having an outlet port sized to snap-fit over an enlarged head at a distal end of a conventional saliva elector valve.
In combination:
- a plastic frustrum-shaped strainer having an open inlet end at its base and an outlet end at its apex, the outlet end having a multiplicity of openings sized to permit saliva, blood, and water to pass out of the strainer and to retain solids within the strainer;
- a plastic strainer cap attached to the strainer and covering the inlet end thereof, the cap having an inlet port where an aspirator device can be attached;
- a transparent, non-rigid plastic housing having an inlet end and an outlet end, the inlet end being shaped to receive the strainer and the strainer cap so that the base of the strainer faces the inlet end of the housing and the apex of the strainer faces the outlet end of the housing and the strainer and the strainer cap are removably secured within the housing, the outlet end of the housing having an outlet port sized to snap-fit over an enlarged head at a distal end of a conventional saliva ejector valve;
- and
- an aspirator device attached to the strainer cap at the inlet port thereof.
