An integral one piece gum soother with a bristle-less wand, an internal vibrating device, a power supply connected to the internal vibrating device, an on/off switch for activating the internal vibrating device, and a mouth guard connected to the bristle-less wand. The mouth guard can extend at a first angle from the bristle-less wand and a flex neck connected to the bristle-less wand can extend at a second angle from the mouth guard. A hollow membrane-free dual chew tip can be connected to the flex neck, wherein the hollow membrane-free dual chew tip can be configured to sustain a reduced temperature from room temperature of at least 20 degrees Fahrenheit if needed.

An oral cleaning device (100) including: a nozzle portion (30) configured to direct a plurality of liquid droplets; an actuator (120); a mode selector (130); a liquid reservoir (38) wherein in operation liquid is moved from the liquid reservoir into an orifice (36) at the proximal end of the nozzle; a system (12, 13, 14, 24) configured to drive a plunger or piston element (16) toward the proximal end of the nozzle to create a spray of liquid droplets when the moving air comes into contact with the liquid; a control unit (15) configured to control the system to drive the plunger a predetermined number of times in response to a single actuation of the actuator, where the control unit is further configured to accept input from the user via the mode selector, and the mode selector is configured for the user to select a number of liquid bursts that will be delivered in response to a single actuation of the actuator.

A toothbrush device includes one electric motor that provides the toothbrush with various frequencies of pulsations that are transmitted in a controlled fashion. The toothbrush device has a brush head with bristle touch-points, a handle, and a carrying case that extends from the head to the handle and holds the electric motor (e.g., a vibration motor). The electric motor generates vibration energy that travels through a shaft of the carrying case to the brush head in generally a single direction to vibrate the brush head. For example, the carrying case of the electric motor contacts the handle at a contact point, which is approximately at the center of the carrying case such that the majority of the vibrations generated by the electric motor are transmitted toward the brush head, while the vibrations towards other directions are minimized.

A bypass flow assembly of an oral irrigator is provided. The oral irrigator may include a handle positionable between a first mode and a second mode and a valve assembly including a bypass valve movable between first and second positions and an inlet valve movable between open and closed positions. The first position of the bypass valve may be associated with the first mode of the handle and the second position of the bypass valve may be associated with the second mode of the handle, such that the bypass valve moves from the first position to the second position when the handle is positioned in the second mode and remains in the second position until the handle is positioned in the first mode. The inlet valve may move between the open and closed positions when the bypass valve is positioned in the first position and the second position.

An oral irrigation device including a reservoir, a tip, and a pump. The pump is operative to draw fluid from the reservoir and propel the fluid to the tip. The pump includes a pump body fluidly connected to the reservoir and the tip, the pump body having an interior wall defining a pump chamber, the pump chamber terminating in an open end and a force exerting assembly that is receive within the pump chamber. The force exerting assembly is movable between a first position and a second position and includes a force exerting member and a compressible sealing member received around the force exerting member. The sealing member engages the interior wall of the pump body during movement from the first position to the second position and movement from the second position to the first position to prevent fluids from escaping the open end of the pump body.

An oral irrigator including a reservoir, a handle in fluid communication with the reservoir, a base in fluid communication with the handle and the reservoir, and a valve assembly. The valve assembly is configured to couple the handle to the base. In a first configuration, the handle valve and base valve are closed to prevent fluid flow out of the handle and the base, respectively, and in a second configuration, the handle valve and the base valve are open to allow fluid to flow between the base and the handle.

A device for stimulating saliva production in a subject includes a source of vibratory motion and a saliva stimulation assembly configured to elicit a salivary response by delivery of a vibratory stimulus. The saliva stimulation assembly includes one or more contact points coupled to the source of vibratory motion and configured to be placed against one or more stimulation sites on one or more portions of skin of the subject. The source of vibratory motion is configured such that, when the source of vibratory motion is operating and the one or more contact points are placed against the stimulation site, the one or more contact points vibrate at a stimulation frequency that produces a stimulus transmitted via the at least one portion of skin to the one or more salivary glands to stimulate saliva production by the one or more salivary glands.

An instrument, article and method are provided for minimizing pain during administration by injection of a liquid, such as, an anesthetic. The instrument has a forward end. A lightpipe mounted freely for vibration projects out of the forward end. The article, a single use tip, is composed of a tip sleeve removably mounted on the forward end of the instrument and a tip member removably mounted on the projecting lightpipe to vibrate a preselected injection site on a human or animal. The tip sleeve and tip member are covered by an elastic overmold that enables the tip member to vibrate freely with respect to the tip sleeve and light from the lightpipe to illuminate the injection site. A vibration unit mounted in the instrument is coupled to the lightpipe. The method is carried out by imparting vibrations and illumination via the lightpipe to the tip member.
