Abstract

Abstract A hygienic tongue cleaning and massage instrument for freeing and removing pathogenic foreign matter entrapped in the papillae of the dorsal mucosa and massaging and scraping the papillae to maintain the papillae in healthy condition. The instrument comprises an elongated handle formed at one end with longitudinally diverging arms the divergent ends of which are interconnected by a longitudinally bowed cross-bar having a laterally centered arched portion and bevelled edge faces defining leading concave contact corners of an angle less than 90* to be alternately engaged in line contact with the side marginal edges of the tongue and medial depressed area of the tongue and, when pressed firmly against the tongue and drawn forwardly from the base of the tongue to the tip, to force entrapped foreign matter from between and strip foreign matter from the papillae and propel it forwardly to the tip to be expelled.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 207 words
A tongue massaging and conditioning instrument for enhancing the circulation through the tongue and freeing the papillae of the dorsal mucosa of pathogenic foreign matter potentially hazardous to health and destructive of the teeth comprising an elongated handle portion terminating at one end in a pair of longitudinally divergent arms mounting at their spaced ends a transversely directed, centrally arched, cross-bar substantially in the plane of said handle and arms, the opposite ends of said cross-bar comprise reversely curved (merge through reversed) arcuate segments merging into the divergent arm ends and thereby forming along one edge a centered convex portion adapted, when said instrument is held to position said one edge against the tongue and drawn forwardly along the tongue, to cooperate with the depressed medial area of the tongue and forming along the opposed edge respective laterally outwardly and downwardly sloping end portions adapted, when said instrument is held to position said opposed edge against the tongue and drawn forwardly along the tongue, to cooperate with the areas of the tongue laterally related to the depressed medial area, said one edge and said opposed edge being bevelled in a direction such that they intersect the inner wall of the cross-bar at an angle less than 90*.
Claim 2
Dependent Claim 207 words
A tongue massaging and conditioning instrument for enhancing the circulation through the tongue and freeing the papillae of the dorsal mucosa of pathogenic foreign matter potentially hazardous to health and destructive of the teeth comprising an elongated handle portion terminating at one end in a pair of longitudinally divergent arms mounting at their spaced ends a transversely directed, centrally arched, cross-bar substantially in the plane of said handle and arms, the opposite ends of said cross-bar comprise reversely curved (merge through reversed) arcuate segments merging into the divergent arm ends and thereby forming along one edge a centered convex portion adapted, when said instrument is held to position said one edge against the tongue and drawn forwardly along the tongue, to cooperate with the depressed medial area of the tongue and forming along the opposed edge respective laterally outwardly and downwardly sloping end portions adapted, when said instrument is held to position said opposed edge against the tongue and drawn forwardly along the tongue, to cooperate with the areas of the tongue laterally related to the depressed medial area, said one edge and said opposed edge being bevelled in a direction such that they intersect the inner wall of the cross-bar at an angle less than 90*.
Claim 3
Dependent Claim 12 words
The instrument of claim 1 wherein said cross-bar is longitudinally outwardly bowed.
