Abstract
Abstract The present dental hygienic device comprises: a drive-rod having a fluid transmission channel therein; a handle enclosing one end of said drive-rod wherein the handle comprises: a means for effectuating an axial reciprocation of said rod, and means for supplying said fluid for and to said fluid transmission channel; an essentially hollow mouthpiece detachably connected to said drive-rod, said mouthpiece molded to conform to the configuration of the oral cavity, and provided with a plurality of discharge ports directed to the teeth and surrounding tissues of the user; piston means depend from the other end of said drive-rod and are integral thereto, said piston means disposed within said hollow mouth-piece, and adapted to allow the egress of said fluid within the mouthpiece, and to effectuate pressurized expulsion of the fluid through said discharge ports; and a labial deflector and bite disposed on said drive-rod in front of the mouthpiece, and positioned directly in front of the anterior teeth when the present device is in use.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
A dental hygienic device, comprising: a. drive-rod having a fluid transmission channel therein; b. a handle enclosing one end of said drive-rod, said handle comprising: i. means for effectuating an axial reciprocation of said rod; and ii. means for supplying said fluid for and to said fluid transmission channel; c. an essentially hollow mouthpiece connected to said drive-rod, said mouthpiece molded to conform to the configuration of the oral cavity, and provided with a plurality of discharge ports directed to the teeth and surrounding tissue of the user; d. piston means depending from the other end of said drive-rod and being integral thereto, said piston means disposed within said hollow mouthpiece and adapted to: allow the egress of said fluid into the mouthpiece and effect the pressurized oscillation of said fluid through said discharge ports; e. a labial deflector disposed on said drive-rod in front of the anterior teeth when the device is in use.
Claim 2
Dependent Claim
155 words
A dental hygienic device, comprising: a. drive-rod having a fluid transmission channel therein; b. a handle enclosing one end of said drive-rod, said handle comprising: i. means for effectuating an axial reciprocation of said rod; and ii. means for supplying said fluid for and to said fluid transmission channel; c. an essentially hollow mouthpiece connected to said drive-rod, said mouthpiece molded to conform to the configuration of the oral cavity, and provided with a plurality of discharge ports directed to the teeth and surrounding tissue of the user; d. piston means depending from the other end of said drive-rod and being integral thereto, said piston means disposed within said hollow mouthpiece and adapted to: allow the egress of said fluid into the mouthpiece and effect the pressurized oscillation of said fluid through said discharge ports; e. a labial deflector disposed on said drive-rod in front of the anterior teeth when the device is in use.
Claim 3
Dependent Claim
28 words
The device as recited in claim 1 in which said device further comprises: fluid regulation means, disposed within said channel, for regulating the flow parameters of said fluid.
Claim 4
Dependent Claim
17 words
The device as recited in claim 2 in which said valve means includes a unidirectional flow element.
Claim 5
Dependent Claim
34 words
The device as recited in claim 1 in which said means for effectuating an axial reciprocation comprises: a. a magnetic transducer, toroidally disposed about said drive-rod; and b. a power source for said transducer.
Claim 6
Dependent Claim
46 words
The device as recited in claim 2 in which said fluid supply means includes: a. a reservoir adapted for filling to a pre-determined volume; and b. a pump for selectably controlling the pressure parameter of said fluid as it is supplied to said fluid transmission channel.
Claim 7
Dependent Claim
31 words
The device as recited in claim 1 in which the discharge ports of said mouthpiece are provided with means for shreading any particles of food that are oscillated through said ports.
Claim 8
Dependent Claim
29 words
The device as recited in claim 6 in which said mouthpiece and said deflector are composed of materials that are lower in density than the enamel of a tooth.
Claim 9
Dependent Claim
54 words
The device as recited in claim 1 in which said piston means in association with said reciprocating drive-rod comprises means for producing alternating pressure and vacuum strokes within said mouthpiece, thereby imparting an oscillatory motion to said fluid and to the incidence of said fluid upon the teeth and the gingival and subgingival areas.
Claim 10
Dependent Claim
16 words
The device as recited in claim 8 in which said piston means comprises a T-shaped element.
Claim 11
Dependent Claim
42 words
The device as recited in claim 8 in which said piston means comprises a circular rotating structure having a plurality of peripheral fins adapted to create, in association with the hygienic fluid, a dynamic oscillatory motion into and out of said ports.
Claim 12
Dependent Claim
36 words
The device as recited in claim 1 in which said mouthpiece is detachable from said drive-rod, thus permitting any number of mouthpieces of different sizes to be alternately used with a single handle and drive-rod combination.
