Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
92 words
A collapsible weight system comprising: diaphragm means for containing a liquid, said diaphragm means including accordion-like wall means for enabling said diaphragm means to be collapsed when not containing the liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining an exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position wherein the exterior shape of the diaphragm means encircles a patient's limb without bending of said exterior shape.
Claim 2
Dependent Claim
92 words
A collapsible weight system comprising: diaphragm means for containing a liquid, said diaphragm means including accordion-like wall means for enabling said diaphragm means to be collapsed when not containing the liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining an exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position wherein the exterior shape of the diaphragm means encircles a patient's limb without bending of said exterior shape.
Claim 3
Dependent Claim
87 words
A collapsible weight system comprising: diaphragm means for containing a liquid, said diaphragm means including accordion-like wall means for enabling said diaphragm means to be collapsed when not containing the liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining a helical exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position encircling a patient's limb with the diaphragm means containing liquid and sealed.
Claim 4
Dependent Claim
87 words
A collapsible weight system comprising: diaphragm means for containing a liquid, said diaphragm means including accordion-like wall means for enabling said diaphragm means to be collapsed when not containing the liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining a helical exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position encircling a patient's limb with the diaphragm means containing liquid and sealed.
Claim 5
Dependent Claim
23 words
The collapsible therapeutic weight system according to claim 1 wherein said means defining an exterior shape of said diaphragm means defines a toroid.
Claim 6
Dependent Claim
20 words

Claim 7
Dependent Claim
35 words
The collapsible therapeutic weight system according to claim 4 further comprising means for mounting the toroid shaped diaphragm means onto a bar, said bar having a substantially smaller diameter than the opening through the toroid.
Claim 8
Dependent Claim
98 words
A collapsible weight system comprising: diaphragm means for containing various quantities of a liquid, said diaphragm means including foldable wall means for enabling the diaphragm means to expand and contract for accommodating said various quantities of liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining an exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position wherein the exterior shape of the diaphragm means encircles a patient's limb without bending of said exterior surface.
Claim 9
Dependent Claim
98 words
A collapsible weight system comprising: diaphragm means for containing various quantities of a liquid, said diaphragm means including foldable wall means for enabling the diaphragm means to expand and contract for accommodating said various quantities of liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining an exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position wherein the exterior shape of the diaphragm means encircles a patient's limb without bending of said exterior surface.
Claim 10
Dependent Claim
93 words
A collapsible weight system comprising: diaphragm means for containing various quantities of a liquid, said diaphragm means including foldable wall means for enabling the diaphragm means to expand and contract for accommodating said various quantities of liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining a helical exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position encircling a patient's limb with the diaphragm means containing liquid and sealed.
Claim 11
Dependent Claim
93 words
A collapsible weight system comprising: diaphragm means for containing various quantities of a liquid, said diaphragm means including foldable wall means for enabling the diaphragm means to expand and contract for accommodating said various quantities of liquid; means defining a sealable opening in said diaphragm means for enabling the filling and emptying of the diaphragm means with the liquid; and means defining a helical exterior shape of said diaphragm means for enabling said diaphragm means to be disposed in a position encircling a patient's limb with the diaphragm means containing liquid and sealed.
