Abstract
Abstract A support frame has an elongate open guide channel with a connection base at one end and a restraint loop at the other. The restraint loop has a through passage connecting with the channel. One end of a flexible conduit with a saliva ejector tip passes through the restraint loop into the channel to slidably engage a conduit connector at the connection base. Preferably, the connector has an elongate conduit receiver on which the conduit is slidable. The receiver flexes to facilitate removal of the conduit from the channel to adjust the overlap of the conduit and the connector to change the extension of the ejector tip with respect to the restraint loop. The conduit connector and ejector tip configuration and material may vary.

Claim 1
Independent Claim
234 words
In a saliva ejector: an elongate support frame having a curved portion at one end adapted to be placed in an oral cavity, said frame being formed with a longitudinal channel extending between end portions of the frame, said channel being open along one side including an outer peripheral side of said curved portion so as to laterally receive a flexible conduit through the open side into a seated position in the channel, a connection base at the other end of the frame comprising a tubular portion establishing a telescopic flow connection, with the adjacent end portion of said flexible conduit, means at said one end of the support frame for embracing the opposite end portion of said conduit and enabling adjusting movements of the conduit therein, said conduit being of a length to provide, when seated in said channel, a portion at said opposite end of said conduit extending beyond the embracing means so as to position an ejector tip thereon, outwardly of said embracing means, and enable adjusting movements to vary its operative position in accordance with said conduit adjusting movements, and upon movement of the tip towards the embracing means enabling distortion of the conduit outwardly away from its seated position through the open side of the channel, and cooperating stop means on said embracing means and said ejector tip to limit movement of said ejector tip toward the embracing means.

Claim 3
Dependent Claim
21 words
A saliva ejector in accordance with claim 1 wherein said embracing means comprises a loop extending loosely around the flexible conduit.
Claim 4
Dependent Claim
46 words
A saliva ejector in accordance with claim 1 wherein said connection base comprises a cylindrical element secured to the frame, a conduit receiver extending from the cylindrical element, an internal passageway through the element and the receiver, and a cylindrical outer surface on the conduit receiver.
Claim 5
Dependent Claim
37 words
A saliva ejector in accordance with claim 1 wherein said connection base comprises a connector element secured in the frame, a flexible sleeve fitted to the connector element, and an elongate conduit receiver fitted to the sleeve.
Claim 6
Dependent Claim
42 words
A saliva ejector in accordance with claim 1 wherein said connection base comprises a connector element secured in the frame, and an elongate conduit receiver extending from the connector element, said receiver being flexibly laterally deflectable relative to the said support frame.
Claim 7
Dependent Claim
41 words
A saliva ejector in accordance with claim 1, wherein said connection base comprises a connector element at said base, and an elongate flexible conduit receiver extending from said connector element, said connector element and said receiver having a slip joint connection.
Claim 8
Dependent Claim
22 words
A saliva ejector in accordance with claim 1, wherein said tubular portion comprises an elongate conduit receiver integrally formed with said frame.
Claim 9
Dependent Claim
178 words
In a saliva ejector: an elongate support frame having a curved portion at one end adapted to be placed in an oral cavity, said frame being formed with a longitudinal side open channel extending between end portions of the frame for embracing and supporting an associated flexible conduit therein, a connection base at the other end of the frame comprising a tubular portion for establishing a telescopic flow connection with the adjacent end portion of the associated flexible conduit, and means at said one end of the support frame for peripherally and slidably embracing the opposite end portion of said conduit and enabling axial adjusting movements of the conduit therethrough, said conduit being of a length to provide a portion at said opposite end of said conduit extending beyond the embracing means so as to normally position an ejector tip thereon outwardly of said embracing means and for adjustable movement inwardly towards said embracing means, and cooperating stop means on said embracing means and said ejector tip to limit movement of said ejector tip toward the embracing means.
Claim 10
