    • The interproximal cleaning apparatus includes a gas reservoir (12) containing a compressed gas, such as CO2, in both liquid and gaseous states. A siphon tube (20) 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 (18) 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 CO2 or a combination of gaseous and liquid CO2 will enter the siphon tube and then the metering valve. The size of the metering valve will limit the volume of the gaseous CO2 to a safe amount, both when liquid CO2 or gaseous CO2 are applied to the metering valve.
    • 邻间清洁装置包括在液态和气态两者中含有诸如CO 2的压缩气体的气体储存器(12)。 当设备处于直立位置时,虹吸管(20)向下延伸到气体储存器的液体区域中。 虹吸管将储存器连接到计量阀(18),计量阀(18)具有计量体积以容纳一定量的液体压缩气体,当液体压缩气体减压并形成气流时,该液体压缩气体足够用于良好的液滴清洁,而不损害牙齿区域 用户。 如果设备严重倾斜或倒过来,气态CO2或气态和液态二氧化碳的组合将进入虹吸管,然后进入计量阀。 当液体CO2或气态二氧化碳被施加到计量阀时,计量阀的尺寸将限制气态二氧化碳的体积达到安全的量。
