Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
A method for relieving cranial tension comprising encircling the cranium with a head band having an inner face adapted to be positioned alongside the cranium, having a first pair of oppositely located lateral expandable compartments on the inner face of the head band, and an anterior and posterior pair of expandable compartments on the inner face of the head band, securing the head band on the cranium in an encircling position in a plane parallel with the plane defined by the eyes and ears and to minimize lengthwise expansion and contraction, sequentially introducing fluid under pressure into only one of said pairs of compartments for applying pressure only in the direction perpendicular to the surface of the portion of the head engaged by said one pair of compartments while removing fluid from only the other of said pairs of compartments for depressurization and introducing fluid under pressure into only the other of said pairs of compartments for applying pressure only in the direction perpendicular to the surface of the portion of the head engaged by said other pair of compartments while removing fluid from said one pair of compartments for depressurization.
Claim 2
Independent Claim
191 words
A method for relieving cranial tension comprising encircling the cranium with a head band having an inner face adapted to be positioned alongside the cranium, having a first pair of oppositely located lateral expandable compartments on the inner face of the head band, and an anterior and posterior pair of expandable compartments on the inner face of the head band, securing the head band on the cranium in an encircling position in a plane parallel with the plane defined by the eyes and ears and to minimize lengthwise expansion and contraction, sequentially introducing fluid under pressure into only one of said pairs of compartments for applying pressure only in the direction perpendicular to the surface of the portion of the head engaged by said one pair of compartments while removing fluid from only the other of said pairs of compartments for depressurization and introducing fluid under pressure into only the other of said pairs of compartments for applying pressure only in the direction perpendicular to the surface of the portion of the head engaged by said other pair of compartments while removing fluid from said one pair of compartments for depressurization.
Claim 3
Dependent Claim
28 words
The method as claimed in claim 1 wherein said cranium encircling head band encompasses said cranium including the brow in a plane approximately parallel to the eye-ear plane.
Claim 4
Dependent Claim
37 words
The method as claimed in claim 1 wherein said cranium encircling head band is manufactured from a material chosen from the group consisting of rubber, rubber substitutes, metal, woven textile fabric, fiberglass, synthetic plastics and mixtures thereof.
Claim 5
Dependent Claim
17 words
The method as claimed in claim 1 wherein each of said expandable compartments comprises an inflatable pouch.
Claim 6
Dependent Claim
17 words
The method as claimed in claim 1 wherein said cranium encircling head band is adjustable in length.
