Abstract
A self-contained hand-operated oral irrigation device for dispensing a pulsing stream of water or therapeutic fluid to the surfaces of the user's oral cavity. The irrigation device has the capability of lavaging at controlled values of pressure and volume of the dispensed fluid and withdrawing the fluid from user's oral cavity for convenient disposal. The irrigation device has a detachable section. Different types of discharge sections include a tooth brush, plaque removal brush and a gum stimulator having lavaging capabilities are provided.
Claims34
A hand-held oral irrigation device comprising:
- a fluid reservoir;
- a longitudinally-spaced fluid discharge section,
- an actuator movable between depressed and extended positions;
- a longitudinally-spaced hand pump responsive to the actuator;
- and
- a longitudinally-spaced body surroundings the hand pump:
- a fluid reservoir and the fluid discharge section extending from opposite sides of the body:
- the actuator extending to about a perimeter of the body when the actuator is in the extended position.
A hand-held oral irrigation device comprising:
- a fluid discharge section;
- an actuator movable in first and second strokes;
- and
- a hand pump including:
- a fluid chamber having an inlet and an outlet, the chamber outlet being in fluid communication with the fluid discharge section;
- and
- first and second pistons movable within the chamber, the first piston being mechanically coupled to the actuator, the first and second pistons defining a first volume within the chamber, the first volume being pressurized by the movement of the first and second pistons during the first stroke;
- and
- a valve disposed in a fluid passage between the chamber outlet and the first volume, pressure in the first volume causing the valve to open and place the chamber in fluid communication with the first volume, whereby the pressure can cause fluid in the first volume to be discharged through the chamber outlet to the fluid discharge section.
A hand-held oral irrigation device comprising:
- a fluid discharge section including a plaque removal brush, the plaque removal brush having a fluid exit passage and a suction passage;
- an actuator movable in first and second strokes;
- and
- a hand pump including
- a fluid chamber having an inlet and an outlet, the chamber outlet being in fluid communication with the fluid discharge section;
- and
- means, responsive to the actuator, for simultaneously pressurizing the fluid chamber, closing the chamber inlet and opening the chamber outlet during the first stroke of the actuator, the means simultaneously creating suction in the fluid chamber, opening the chamber inlet and closing the chamber outlet during the second stroke of the actuator;
- the fluid exit and suction passages of the plaque removal brush being connectable to the means.
A hand-held oral irrigation device comprising:
- a fluid discharge section including a gum stimulator, the gum stimulator having a body, a multitude of exit jetting ports and first and second tip ends;
- an actuator movable in first and second strokes;
- and
- a hand pump including:
- a fluid chamber having an inlet and an outlet, the chamber outlet being in fluid communication with the fluid discharge section;
- and
- means, responsive to the actuator, for simultaneously pressurizing the fluid chamber, closing the chamber inlet and opening the chamber outlet during the first stroke of the actuator, the means simultaneously creating suction in the fluid chamber, opening the chamber inlet and closing the chamber outlet during the second stroke of the actuator;
- the chamber having a volume defined by the means and a chamber wall, the chamber further having a suction pod in fluid communication with the volume during the first stroke;
- the first tip end of the gum stimulator being in fluid communication with the outlet port and the second end of the gum stimulator being in fluid communication with the suction port.
