Abstract

A collapsible therapeutic weight system is provided which includes a diaphragm having a accordion-like wall for enabling the diaphragm to be expanded and contracted to accommodate various amounts of a liquid and fully collapsible when not containing a liquid. A sealable opening in the diaphragm is provided for enabling the filling and emptying of the diaphragm and the diaphragm is shaped for enabling the diaphragm to be disposed in a position encircling a patient'"'"'s limb.

Claims

1. 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.

3. The collapsible therapeutic weight system according to claim 1 wherein said means defining an exterior shape of said diaphragm means defines a toroid.

4. The collapsible therapeutic weight system according to claim 3 wherein said diaphragm means is collapsible along a longitudinal axis thereof.

5. 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.

2. 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.

6. 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.

8. The collapsible therapeutic weight system according to claim 6 wherein said means defining an exterior shape of said diaphragm means defines a toroid.

9. The collapsible therapeutic weight system according to claim 8 wherein said diaphragm means is collapsible along a longitudinal axis thereof.

7. 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.
