Abstract

Abstract A hollow U-shaped rubber dam device which eliminates the need for a dental assistant to handle a suction tube to maintain a dry field of work and prevent water from a dental drill from running uncontrollably over the patient by providing a structure which by itself maintains a dry field for dental work. The device is constructed so as to provide a suction path through the hollow interior for connection to the standard suction coupling of a dental stand, and to accept the standard dental suction tube fitting as an easily attachable and detachable part. The hollow interior suction path includes means for cleaning out and sterilizing the interior passages formed within a portion of the body of the device. The device is suitably made of radio-transparent material, such as molded plastic, and may remain in place while X-rays are taken without producing shadows on the exposed X-ray film.

Claim 8
Dependent Claim 192 words
A rubber dam device for dental use comprising in combination, (a) a U-shaped frame having a horizontal arm and a pair of vertical arms, one of said pair of vertical arms extending upward from one end of said horizontal arm and the other of said pair of vertical arms extending upward from the other end of said horizontal arm, (b) said horizontal arm having (1) a hollow passage therethrough substantially from one end to the other, (2) means for connecting one open end of a dental suction tube to said horizontal arm so that it communicates with the said passage therethrough, (3) a plurality of spaced apart apertures through said horizontal arm from the said passage to the outside surface which when the dam device is in use faces the patient, (c) a hollow suction stem, one open end of which connects to said horizontal arm and communicates with the said horizontal arm hollow passage, and the other end of which is adapted for connection to the suction coupling of a dental stand, (d) means carried by said vertical and horizontal arms for detachably holding a rubber dam membrane in operative position.
Claim 9
Dependent Claim 192 words
A rubber dam device for dental use comprising in combination, (a) a U-shaped frame having a horizontal arm and a pair of vertical arms, one of said pair of vertical arms extending upward from one end of said horizontal arm and the other of said pair of vertical arms extending upward from the other end of said horizontal arm, (b) said horizontal arm having (1) a hollow passage therethrough substantially from one end to the other, (2) means for connecting one open end of a dental suction tube to said horizontal arm so that it communicates with the said passage therethrough, (3) a plurality of spaced apart apertures through said horizontal arm from the said passage to the outside surface which when the dam device is in use faces the patient, (c) a hollow suction stem, one open end of which connects to said horizontal arm and communicates with the said horizontal arm hollow passage, and the other end of which is adapted for connection to the suction coupling of a dental stand, (d) means carried by said vertical and horizontal arms for detachably holding a rubber dam membrane in operative position.
