The dental suction device comprises a pliable tube having a first end for connection to a vacuum source and a second end that can be looped to form a suction end for positioning in a patient's mouth. The loop is adjustably secured by a pair of retaining collars positioned a certain distance apart from each other along the second end of the tube and connected together by a tie. The loop, adjusted to accommodate the shape of the patient's mouth, is secured around the terminal end of a row of teeth in the patient's mouth. In this way, the dental suction device can be maintained and operated in the patient's mouth during a dental procedure. ## Claims ### Claim 1 A dental suction device comprising: a pliable semi-rigid tube having a first end for connection to a vacuum source and a second end adjustably bendable around a terminal end of a row of teeth in a patient's mouth to form a loop accommodating a shape of the patient's mouth, the second end having a plurality of apertures through which fluid is suctioned from the patient's mouth; one or more spaced-apart pairs of resilient retaining collars, wherein each of the one or more pairs of resilient retaining collars is spaced apart at a certain distance along the second end of the tube and engaged therewith; and a pliable tie; wherein each of the one or more pairs of resilient retaining collars is provided with a hole therethrough to threadably receive therethrough the pliable tie for interconnecting a pair of the resilient retaining collars whereby the pliable tie may be secured in an interproximal space between two teeth at the terminal end of the row of teeth to thereby secure the looped second end of the device in the patient's mouth. ### Claim 2 (depends on 1) The dental suction device according to claim 1, wherein the second end of the pliable tube terminates in a flared rim. ### Claim 3 (depends on 1) The dental suction device according to claim 1, wherein the tie is adjustably connected to the pair of retaining collars to allow tightening and loosening of the second end of the tube around the row of teeth. ### Claim 4 (depends on 1) The dental suction device according to claim 1, wherein each retaining collar in the pair allows for each end of the tie to be tightly caught between the interior of the respective retaining collar and the exterior of the tube, wherein the tie connects the pair of retaining collars such that pulling or releasing a free end of the tie causes shortening or lengthening of the connection between the respective retaining collars in the pair, respectively. ### Claim 5 (depends on 1) The dental suction device according to claim 1, wherein the tie is dental floss. ### Claim 6 (depends on 1) The dental suction device according to claim 1, wherein the tie is an elastic material. ### Claim 7 (depends on 6) The dental suction device according to claim 6, wherein the elastic material is latex or non-latex rubber. ### Claim 8 (depends on 1) The dental suction device according to claim 1, wherein the retaining collars have a diameter large enough to be threadably positioned onto the tube and small enough to be retained by a flared rim on the second end of the tube. ### Claim 9 (depends on 1) The dental suction device according to claim 1, wherein the one or more spaced-apart pairs of resilient retaining collars comprises a single pair of retaining collars. ### Claim 10 (depends on 1) The dental suction device according to claim 1, wherein the one or more spaced-apart pairs of resilient retaining collars comprises two pairs of retaining collars. ### Claim 11 (depends on 1) The dental suction device according to claim 1, wherein the plurality of apertures at the second end of the tube are circular in shape. ### Claim 12 (depends on 11) The dental suction device according to claim 11, wherein the diameter of the apertures is from 0.25 mm to 3 mm. ### Claim 13 (depends on 1) The dental suction device according to claim 1, wherein the plurality of apertures at the second end of the tube are slits. ### Claim 14 (depends on 1) The dental suction device according to claim 1, wherein the apertures are evenly distributed at the second end of the tube. ### Claim 15 (depends on 1) The dental suction device according to claim 1, wherein the apertures are unevenly distributed at the second end of the tube. ### Claim 16 (depends on 1) The dental suction device according to claim 1, wherein the length of the second end of the tube is from 2 cm to 20 cm to form a loop from about 1 cm to 10 cm. ### Claim 17 (depends on 1) The dental suction device according to claim 1, wherein the tube has an internal diameter of from 2 mm to 10 mm. ### Claim 18 (depends on 1) The dental suction device according to claim 1, further comprising a valve for modulating the rate of fluid removal from the patient's mouth. ### Claim 19 (depends on 18) The dental suction device according to claim 18, wherein the valve is located between the first and second end of the pliable tube. ### Claim 20 (depends on 18) The dental suction device according to claim 18, wherein the valve has a plurality of operating positions and is moveable between said operating positions. ### Claim 21 (depends on 18) The dental suction device according to claim 18, wherein the valve is operable by the patient.
