Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 345 words
A high volume oral evacuator which comprises: (a) a tubular handle adapted to be connected to a source of vacuum; (b) a tubular tip member; (c) a rigid sleeve member having a bevelled tapered intake end with other end secured over said tip member and extending outwardly beyond outer end of said tip member; (d) means providing a swivel joint of said tip member with said handle whereby said tip member may be freely rotated relative to said handle to variously position the bevelled intake end of said sleeve member within a mouth of a patient; (e) an operating ring fixed to said tip member containing said swivel joint in position to be manipulated for turning said tip member relative to said handle by fingers of a hand of an operator holding said handle; and (f) a mirror connected at an angle to the bevelled tapered intake end of said sleeve member, wherein said mirror further comprises a shaft pivotally supported on said sleeve member and adjacent to the bevelled intake end thereof, that further comprises a means for flipping over said mirror and locking said shaft in a stationary position so that in a down position said mirror can be used as a retractor for cheeks and tongue and in a up position as a viewing tool for the upper teeth, wherein said means for flipping over said mirror and locking said shaft in a stationary position comprises; (i) a reduced threaded shaft member affixed to end of said shaft of said mirror; (ii) a arm having a transverse threaded aperture in enlarged end thereof that is threadably mounted onto said reduced threaded shaft member so that said arm can flip over said mirror via said shaft of said mirror; (iii) a nut threadably mounted onto said reduced threaded shaft member to secure said arm thereon; and (iv) at least one arm holding ear portion affixed to said rigid sleeve member on either side of said shaft of said mirror so that said arm holding ear portion thus prevents said arm from moving therefrom.
