Ergonomic high volme evacuator system
An ergonomic high volume evacuator system provides a tapered tubular evacuator tool having a body defining a medial channel with an angulated mirrored guard having an optically reflective insert adjacent a beveled input orifice. A flexible evacuation hose having an integral coil spring and a vacuum connector pneumatically releasably interconnect the evacuator tool with a vacuum source. An axially rotatable evacuator tool connector provides a releasable pneumatic and fluidic sealed interconnection between the evacuator tool and the evacuation hose.
1 . An ergonomic system for a single dental professional to simultaneously evacuate dental debris from a patient's mouth, visualize a dental instrument and a surface being worked upon, the system pneumatically communicating with a dental vacuum source and autoclavable for sterilization, the system comprising in combination:
an evacuator tool having a tubular body with a first end portion, a spaced apart second end portion and defining a medial channel extending therebetween, the first end portion defining a beveled input orifice having a mirrored guard with an optically reflective insert proximate the input orifice and guard flanges interconnecting circumferential edge of the mirrored guard and circumferential edge portion of the input orifice;
a flexible evacuation hose carrying an evacuator tool connector at a first end portion, the evacuator tool connector providing an axial through channel communicating with medial channel defined by the evacuation hose and providing a releasable axially rotatable pneumatically sealed interconnection with the second end portion of the evacuator tool; and
a vacuum connector carried at second end portion of the evacuation hose communicating with the evacuation hose medial channel, the vacuum connector having a portion for releasable pneumatically sealed engagement with the vacuum source and a tool holder for releasably positionally maintaining the evacuator tool connector and interconnected first end portion of the evacuation hose.
2 . The system of claim 1 wherein:
the mirrored guard defines a circular cavity in surface proximate to the input orifice and the optically reflective insert is positionally maintained within the circular cavity by overlapping inner circumferential edge portions of the circular cavity over outer circumferential edge portions of the optically reflective insert.
3 . The system of claim 1 wherein:
the tool holder has a first half and a second half spaced apart by a vertical slot, the first half and second half having downwardly and inwardly tapering configurations to positionally retain the evacuator tool connector therebetween.
4 . The system of claim 1 wherein:
the optically reflective insert is Mylar®.
5 . The system of claim 1 wherein:
the optically reflective insert is polished steel.
6 . The system of claim 1 wherein:
the optically reflective insert is a mirror.
7 . The system of claim 1 wherein:
evacuator tool has an elongate axis and the bevel of the input orifice relative to the elongate axis is between 25 degrees and 50 degrees.
8 . The system of claim 1 wherein:
evacuator tool has an elongate axis and the bevel of the input orifice relative to the elongate axis is 30 degrees.
9 . The system of claim 1 wherein:
evacuator tool has an elongate axis and the angle of the mirrored guard relative to the elongate axis is between 25 degrees and 50 degrees.
10 . The system of claim 1 wherein:
evacuator tool has an elongate axis and the angle of the mirrored guard relative to the elongate axis is 30 degrees.
11 . The system of claim 1 wherein:
angle of the mirrored guard relative to the beveled input orifice is between 90 degrees and 130 degrees.
12 . The system of claim 1 wherein:
angle of the mirrored guard relative to the beveled input orifice is 120 degrees.
13 . The system of claim 1 wherein:
the evacuation hose is formed of silicone and has an internal coil spring to prevent collapsing under vacuum.
