Abstract: A tongue cleaning device includes a tool head defining a trough that delivers the vacuum flow from an inlet to the inner surface disposed above a working edge for efficient removal of debris. The trough has a defined rear wall giving it a defined width. This allows the vacuum flow to be directed to where it is needed to remove debris. One configuration of the device has a head that defines a liquid distribution channel with an outlet disposed in front of the working edge with a supply of liquid being removably in fluid communication with the liquid distribution channel. The liquid supply being a bulk supply or a hand held bottle with a supply tube extending down the handle of the device. Another configuration of the device includes vacuum control openings controlled by the user's finger.

Abstract: A portable, self-contained vacuum tongue cleaning device uses a removable cleaning head so that different heads can be used with different users. The device includes a debris and saliva separator that removes the debris and saliva from the vacuum flow. This separator is carried by the cleaning head in order to minimize required cleaning of the base of the device. The base carries a vacuum pump, a power supply, a switch, and an inlet that allows the power supply to be recharged. The device is configured for emergency use in an oral surgeon's office wherein vacuum flow is required during surgeries.
