Palm pressure points have been identified by a number of researchers including Scarborough et. al. in J Am Dent Assoc, Vol 139, No 10, whose article “Altering the Gag Reflex Via a Palm Pressure Point.” from the same issue is incorporated by reference herein in its entirety.
The point identified by Scarborough et. al. as well as others known in the art have been demonstrated to affect physiological phenomena relevant to oral care, including for instance modification of the gag reflex. The various pressure points present in the hand of a user which have been identified to have physiological effect will hereinafter be referred to collectively as “pressure point.”
Consequently, devices are disclosed herein for both grossly and selectively applying force upon the pressure points disposed upon a pressure point on a user's palm.
According to certain embodiments of the present disclosure, an oral utensil includes at least an elongated body having a longitudinal axis extending therethrough, a distal end portion configured for executing an oral care task, and a proximal end portion having a protrusion extending in a substantially orthogonal relation from the longitudinal axis and positioned upon the proximal end portion such that it abuts the palm of a user.
According to further embodiments of the present disclosure, an oral utensil includes an elongated body having a longitudinal axis extending therethrough, a distal end portion configured for executing an oral care task, and a proximal end portion having a protrusion extending in a substantially orthogonal relation from the longitudinal axis and positioned upon the proximal end portion such that it selectively abuts the palm of a user at a point P.
According to further embodiments of the present disclosure, the protrusion is sized and shaped to depress pressure point as described by Scarbourough et al.
According to further embodiments of the present disclosure, the distal end portion comprises a tongue brush.
According to further embodiments of the present disclosure, the distal end portion comprises a tooth brush.
According to further embodiments of the present disclosure, the distal end portion comprises a portion of dental floss.
According to further embodiments of the present disclosure, the distal end portion and proximal end portion a separate and distinct members having a complementary male-female coupling allowing them to be coupled to one another.
According to further embodiments of the present disclosure, the coupling is substantially circular, thereby allowing rotation of the distal-end portion relative to the proximal-end portion.
According to further embodiments of the present disclosure, there are detents disposed upon the rotational path of the coupling operatively configured to interfere with one another at at least two points along the rotational path, thereby defining positions.
According to further embodiments of the present disclosure, a section of the surface of the proximal end portion is modified by means of one at least one of the following: a embossed pattern, a recessed pattern, or a portion of material having a distinct texture, surface finish, or appearance from the remainder of the proximal end portion.
According to further embodiments of the present disclosure, wherein there is a section of material disposed upon the surface of the proximal end portion selected from either thermoplastic or silicone.
According to further embodiments of the present disclosure, there is an aperture extending through the proximal end portion in substantially orthogonal relation to the long axis of the oral utensil.
