Abstract
The interproximal cleaning apparatus includes a gas reservoir () containing a compressed gas, such as CO, in both liquid and gaseous states. A siphon tube () extends down into the liquid region of the gas reservoir when the apparatus is in an upright position. The siphon tube connects the reservoir to a metering valve () which has a metered volume to accommodate an amount of liquid compressed gas which is sufficient for good liquid droplet cleaning when it decompresses and forms a gaseous stream, without damage to the dental regions of the user. If the apparatus is severely tilted or turned upside down, gaseous COor a combination of gaseous and liquid COwill enter the siphon tube and then the metering valve. The size of the metering valve will limit the volume of the gaseous COto a safe amount, both when liquid COor gaseous COare applied to the metering valve.
