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.

Abstract: A collapsible weight system provides a collapsible/expandable diaphragm for containing a liquid which includes a closed hub disclosed on one end thereof and an open hub disposed on another end thereof. A tubular cap is provided to seal the collapsible/expandable diaphragm while engaging both the closed hub and the open hub to provide axial support of the diaphragm. A pin locking system is provided in order to lock the tubular cap to a bar for lifting the weights. When the bar is engaged and locked with the cap, it extends therethrough providing additional strength and support for the collapsible/expandable diaphragm.
