Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A tongue depressor, comprising; an elongated member arcuately bowed longitudinally, relatively narrow and thin when compared with its length, formed from rigid material having a transverse wide V-shape between its end portions and having parallel top and ventral surfaces at respective end portions terminating in part circular end surfaces and having opposite side surfaces converging toward one end portion; an endless upstanding rib on said top surface adjacent the opposite side surfaces and part circular end surfaces; and, a friction inducing fish scale-like texture on the ventral surface of each said end portion for resisting lateral and outward longitudinal movement of the depressor relative to a patient's tongue in response to pressure manually applied to the depressor when in use.
Claim 2
Dependent Claim
120 words
A tongue depressor, comprising; an elongated member arcuately bowed longitudinally, relatively narrow and thin when compared with its length, formed from rigid material having a transverse wide V-shape between its end portions and having parallel top and ventral surfaces at respective end portions terminating in part circular end surfaces and having opposite side surfaces converging toward one end portion; an endless upstanding rib on said top surface adjacent the opposite side surfaces and part circular end surfaces; and, a friction inducing fish scale-like texture on the ventral surface of each said end portion for resisting lateral and outward longitudinal movement of the depressor relative to a patient's tongue in response to pressure manually applied to the depressor when in use.
Claim 3
Dependent Claim
115 words
A tongue depressor, comprising; an elongated member arcuately bowed longitudinally, relatively narrow and thin when compared with its length, formed from rigid material having opposite side surfaces and having a transverse wide V-shape between its end portions and having parallel top and ventral surfaces at respective end portions terminating in part circular end surfaces; an endless upstanding rib on said top surface adjacent the opposite side surfaces and part circular end surfaces; and, a friction inducing fish scale-like texture on the ventral surface of one end portion for resisting longitudinal movement of the depressor in an outward direction relative to a patient's tongue in response to pressure manually applied to the depressor when in use.
Claim 4
Dependent Claim
115 words
