Abstract:
1. A device comprising: a pressure chamber that includes a seal element and a casing, the casing defining a pressure controlled environment and being configured to expand open to facilitate installation of a limb of a patient in the casing, the pressure chamber comprising an elastic shell fitted about an exterior surface of the casing that is configured to bias the casing closed during operation of the pressure chamber yet stretch to allow for expansion of the casing to facilitate insertion or removal of the limb from the casing, the seal element configured to seal the pressure chamber about the limb; and a control unit connectable to the pressure chamber and adapted, when connected to the pressure chamber, to alternatingly introduce a negative pressure to the pressure chamber during a negative pressure period and release the negative pressure from the pressure chamber to restore the pressure chamber to approximately atmospheric pressure during an atmospheric pressure period.
