A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

A suction assembly, toothbrush, and method are provided that suction fluids and debris resulting from brushing. The suction assembly includes a housing configured to couple to the toothbrush so that a portion extends around sides and a back of the toothbrush head and is spaced from the toothbrush head by a gap. The suction assembly further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.

A dental valve device has a valve body having a tip receiving end having a flexible tubing extending outwardly from the tip receiving end with the flexible tubing having a flexible tubing opening, a hose receiving end, a lumen formed between the flexible tubing opening and the hose receiving end, and a partial opening formed in the valve body, and a rotatable valve sealing body adapted to be inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the flexible tubing opening and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening.

A disposable dental valve device is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, a partial opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening, the rotatable valve sealing body having a check valve positioned on the tip receiving opening, and the rotatable valve sealing body having a top and a handle portion connected to the top.

A disposable dental valve device is disclosed having a valve body having an interior, a tip receiving end for receiving a tip, a socket hose receiving end for receiving a tube having a beaded end, a lumen formed between the tip receiving end and the socket hose receiving end, and a partial opening formed in the valve body, a rotatable valve sealing body adapted to be inserted into the partial opening, and the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the socket hose receiving end.

A suction valve for a dental treatment unit is connected to a downstream suction system and includes input and output conduits; a valve seat interposed therebetween; a diaphragm defining a chamber by moving between a resting position against the valve seat, blocking flow between the input and output conduits, and an active position distanced from the valve seat, allowing fluids to pass; a connecting conduit between the chamber and the output conduit and having an air entry point; and a pilot valve switched between a resting position, allowing air passage to the chamber through the connecting conduit and having a first portion, a closing point, and a second portion, and an active portion blocking air passage. A non-return valve at the entry point prevents an input flow to the connecting conduit and the upwelling of liquids from the output conduit to the pilot valve and/or the chamber.

A dental valve device having a disposable turret is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, an opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving end opening and a hose receiving end opening, the rotatable valve sealing body having an outer surface having an indentation formed in the outer surface adjacent to the tip receiving end opening with the indentation having an upper ramp portion, a lower ramp portion, and an end having a tab portion.
