Abstract
Abstract A splatter guard for air polishing dental devices includes a generally bell-shaped flexible member which is designed to be attached to the distal end of the air polishing device. The bell-shaped member creates a chamber which is designed to receive the back splash and splattered fluids emanating from the nozzle of the air polishing device. In this manner, the fluid from the air polishing dental device is prevented from being splattered or splashed against a patient's soft tissues, a patient's face or clothes, or the operator of the device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A splatter guard in combination with a fluid polishing dental device, said dental device having an outlet conduit extending from a distal end thereof terminating at an outlet nozzle, said splatter guard comprising: a) a flexible generally bell-shaped member having an internal chamber with a smaller diameter proximal end merging with a larger diameter distal end at an interface plane, said distal end having an enlarged opening; and b) means for attaching said bell-shaped member adjacent said distal end of said fluid polishing dental device, said means for attaching comprising an attachment opening in said smaller diameter proximal end sized to closely receive and engage a periphery of a proximal portion of said outlet conduit with said enlarged opening facing away from said dental device and with said outlet conduit extending within said chamber, said interface plane being located approximately equidistant from said attachment opening and said enlarged opening, said outlet conduit and outlet nozzle being located proximal of said interface plane; c) said bell-shaped member shielding said nozzle of said fluid polishing dental device and preventing fluid emanating from said nozzle from contacting a patient or operator in undesired locations.
Claim 2
Dependent Claim
191 words
A splatter guard in combination with a fluid polishing dental device, said dental device having an outlet conduit extending from a distal end thereof terminating at an outlet nozzle, said splatter guard comprising: a) a flexible generally bell-shaped member having an internal chamber with a smaller diameter proximal end merging with a larger diameter distal end at an interface plane, said distal end having an enlarged opening; and b) means for attaching said bell-shaped member adjacent said distal end of said fluid polishing dental device, said means for attaching comprising an attachment opening in said smaller diameter proximal end sized to closely receive and engage a periphery of a proximal portion of said outlet conduit with said enlarged opening facing away from said dental device and with said outlet conduit extending within said chamber, said interface plane being located approximately equidistant from said attachment opening and said enlarged opening, said outlet conduit and outlet nozzle being located proximal of said interface plane; c) said bell-shaped member shielding said nozzle of said fluid polishing dental device and preventing fluid emanating from said nozzle from contacting a patient or operator in undesired locations.
