Abstract
Abstract A device for use in oral and dental hygiene wherein an oral irrigator is provided for connection to a conventional syringe or the like for applying fluid under pressure to the irrigator. The irrigator has a downwardly tapered tip with one or more longitudinally formed channels fluidly connected to the fluid supply syringe, with the remaining circumference of the irrigator tip capable of holding away the gum tissue, whereby irrigating fluid under pressure is applied into the base of a periodontal pocket for cleansing purposes with the channels also providing an exit for the fluid and debris to prevent undue pressure build-up.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
121 words
An oral irrigator for attachment to and use with an instrument capable of selectively supplying fluid under pressure to the oral irrigator comprising: means for fluid attachment to the instrument; stem means fluidly secured to said attachment means and having an open free end; and tip means having a conical body fluidly secured to said stem means free end, said body tapered from a large end adjacent to said free end to a pointed end, one or more channels formed circumferentially about and within said body and extended longitudinally thereof, whereby fluid can be emitted at said pointed end, said large end having one or more grooves formed therein and disposed about its periphery, said grooves extended substantially parallel said channels.
Claim 2
Dependent Claim
121 words
An oral irrigator for attachment to and use with an instrument capable of selectively supplying fluid under pressure to the oral irrigator comprising: means for fluid attachment to the instrument; stem means fluidly secured to said attachment means and having an open free end; and tip means having a conical body fluidly secured to said stem means free end, said body tapered from a large end adjacent to said free end to a pointed end, one or more channels formed circumferentially about and within said body and extended longitudinally thereof, whereby fluid can be emitted at said pointed end, said large end having one or more grooves formed therein and disposed about its periphery, said grooves extended substantially parallel said channels.
Claim 3
Dependent Claim
133 words
An oral irrigator for attachment to and use with an instrument capable of selectively supplying fluid under pressure to the oral irrigator comprising: means for fluid attachment to the instrument; stem means fluidly secured to said attachment means and having an open free end; and tip means having a conical body with a large end tapering to a small end, said large end attached to said free end, and a plurality of channels formed within said conical body and extended longitudinally thereof, said channels each having one end thereof fluidly connected to said free end and each channel open to the periphery of said conical body substantially the entire length thereof, said large end having one or more grooves formed therein and disposed about its periphery, said grooves extended substantially parallel said channels.
Claim 4
Dependent Claim
133 words
An oral irrigator for attachment to and use with an instrument capable of selectively supplying fluid under pressure to the oral irrigator comprising: means for fluid attachment to the instrument; stem means fluidly secured to said attachment means and having an open free end; and tip means having a conical body with a large end tapering to a small end, said large end attached to said free end, and a plurality of channels formed within said conical body and extended longitudinally thereof, said channels each having one end thereof fluidly connected to said free end and each channel open to the periphery of said conical body substantially the entire length thereof, said large end having one or more grooves formed therein and disposed about its periphery, said grooves extended substantially parallel said channels.
Claim 5
Dependent Claim
94 words
An oral irrigator tip comprising: a conical body having a large end and a small end and tapered from said large end to the small end; said large end having a fluid receiving cavity formed therein for connection to a fluid transmitting element; and one or more channels formed in and about the circumference of said conical body, each channel extended longitudinally of and substantially the entire length of said conical body, and having one end open to said cavity for receiving fluid therefrom for flow to the small end of said conical body.
Claim 6
Dependent Claim
94 words
An oral irrigator tip comprising: a conical body having a large end and a small end and tapered from said large end to the small end; said large end having a fluid receiving cavity formed therein for connection to a fluid transmitting element; and one or more channels formed in and about the circumference of said conical body, each channel extended longitudinally of and substantially the entire length of said conical body, and having one end open to said cavity for receiving fluid therefrom for flow to the small end of said conical body.
Claim 7
Dependent Claim
27 words
An oral irrigator tip as described in claim 3 and further wherein each said claimed is open its entire length to the periphery of said conical body.
Claim 8
Dependent Claim
72 words
An oral irrigator tip as described in claim 3, wherein a fluid passage is formed in said conical body between said cavity and the one end of each channel, each said fluid passage extended parallel to the longitudinal axis of said conical body, whereby fluid is transmitted through each fluid passage and into an associated channel for flow parallel to the said axis of said conical body toward said small end thereof.
