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.

An oral suction device provides an oral suction screen over the oral cavity of a patient by providing upper and lower suction wings attached to a manifold. The wings are inserted between the upper and lower lips and arches of a patient, respectively, and serve to capture aerosols which would otherwise be ejected from the oral cavity. A tongue/cheek retractor, also in pneumatic communication with the manifold, serves to extract saliva and other products from the oral cavity while also preventing the tongue and cheeks from ingress of the workspace for the dental procedure.

An oral cavity suction device comprising a vacuum hose and a vacuum tip including a tube body having a base end and a distal end that is a suction opening. The oral cavity suction device includes a hose-side light-outputting end face in the vacuum hose arranged to face the distal end side of the vacuum hose to output light input from a light source. The oral cavity suction device includes a light guiding element in the vacuum tip, with a tip-side light-receiving end face arranged to face the base end side of the vacuum tip to guide light input from the tip-side light-receiving end face and project the light. The hose-side light-outputting end face and the tip-side light-receiving end face allow light to be transmitted in a state in which the vacuum tip is completely connected to the vacuum hose.

A vacuum light apparatus is configured with a light source that illuminates a light pipe forming a light pipe conduit configured to draw vacuum therethrough. The vacuum light apparatus has a light switch to turn the light source on and off, dim up and down and a vacuum actuator to adjust the amount of vacuum on the projection end of the light pipe. The light source may receive power from a battery, or from a power cable. The power cable may be detachably attached to the vacuum light apparatus, such as to the body. An exemplary vacuum light apparatus may be used for dental applications to provide illumination in an oral cavity or mouth while providing suction to draw away saliva, other fluids and particles from the procedure.

To allow a vacuum tip and a vacuum hose to be attached to and detached from each other in a physical manner in a case of installing a light source on the vacuum tip side, it is configured that electrical connection between the vacuum tip and the vacuum hose is established in association with the attachment and detachment. An oral suction device including a vacuum hose connected to a suction source and a vacuum tip having a tube body that has a proximal end connectable to a distal end of the vacuum hose and a distal end as a suction port, includes a light source provided in the vacuum tip to illuminate inside of an oral cavity, a hose-side electrode, provided at the distal end of the vacuum hose, for supplying power from a power supply to the light source, and a tip-side electrode, provided at the proximal end of the vacuum tip and electrically connected to the light source, for receiving the power from the hose-side electrode.

The present invention wants to provide an improved tongue cleanser showing an improved cleaning effect. For this, a tongue cleanser is suggested having an essentially disc-shaped body, which is provided on its use-side front surface with a profiling suitable for superficially scraping impurity adherent to the human tongue and which forms a hose connection, which communicates with the profiling.

An intraoral device for dental isolation and fluid evacuation is disclosed. The device includes a first flap and a second flap positioned adjacent to the first flap to form an evacuation chamber, the second flap including a plurality of peaks and troughs forming a waveform shape at a first edge and a second edge of the second flap, the plurality of peaks and troughs forming a plurality of channels in fluid communication with the evacuation chamber; and an evacuation source connection portion including an opening that is in fluid communication with the evacuation chamber and configured to facilitate fluid evacuation when the evacuation source connection portion is attached to an external vacuum suction device, wherein an interior second flap surface is configured to touch an interior first flap surface at the plurality of troughs at least when suction is applied by the external vacuum suction device.

An oral suction device includes a vacuum hose connected to a suction source, a vacuum tip having a tube body that has a proximal end connectable to a distal end of the vacuum hose and a distal end as a suction port, and a bag-shaped light source holder provided on a tube-body outer surface, on a tube-body inner surface, or in a tube wall of the vacuum tip or at locations corresponding to a combination thereof, extending along a longitudinal direction of the vacuum tip, and having an opening at one end.
