Abstract

Abstract The present invention relates to an oral lavage apparatus. The apparatus includes a hand-held trigger actuated device for providing liquid in streams of pulses and an external reservoir for holding the liquid to be distributed through the device. The invention is additionally chracterized in that all elements may be easily stored inside the reservoir when the trigger actuated device is not in use. This provides the two-fold benefit of portability while maintaining a sufficient amount of liquid to supply to the hand-held device.
