Abstract: An oral irrigator includes a drive assembly, a pump assembly, and a flexible membrane seal. The drive assembly is received within a housing. The pump assembly is positioned at least partially within a pump chamber. The pump assembly includes a piston and a connecting rod coupled to the drive assembly, the connecting rod movable between first and second positions through operation of the drive assembly. The flexible membrane seal extends from an interior surface of the pump chamber to the connecting rod to fluidly seal an open end of the pump chamber. The flexible membrane seal deforms from a first orientation to a second orientation as the connecting rod moves from the first position to the second position.

Abstract: A handheld, therapeutic cleansing system includes a skin or body brush with a rotating bristle head and an associated water spray. The body brush includes a housing, a brush assembly connected to the housing, and a drive assembly for rotating the brush assembly. The brush assembly includes a plurality of bristles and is rotated by the drive assembly. The drive assembly may include a motor having a drive shaft, a worm gear coupled to the drive shaft of the motor and rotatable therewith, and at least one gear engaged with the worm gear and rotatable therewith. During operation, the at least one gear couples to the brush assembly and rotates the brush assembly as the worm gear rotates. Water spray is provided through a connection with a water supply and spray nozzles adjacent to the bristles.
