Therapeutic limb covering using hydrostatic pressure
First Claim
1. A therapeutic limb covering for treatment of chronic swelling comprising:
- a substantially non-distensible shell having an inner surface;
an elastic double-walled bladder joined to the inner surface of the shell, the bladder containing a liquid;
a structural support between the bladder and the shell to resist collapse of the covering under the weight of the liquid in the bladder;
wherein the double-walled bladder has an outer periphery along which the walls are bonded to each other and along which the bladder is bonded to the shell.

Abstract
The present invention provides a therapeutic limb covering and an associated method of treating chronic swelling of a limb. The limb covering is uses hydrostatic pressure provided by liquid contained within the covering to apply pressure to the limb. The limb covering comprises a substantially non-distensible flexible outer layer, a distensible flexible inner layer joined together and a liquid tight bladder therebetween. The covering may be adapted for releasable securement about a limb such as an arm or a lower leg and foot of a patient. After placement on the limb, when the bladder is filled with a liquid, such as water, it expands to contact and apply pressure to the limb.
