Abstract:
1. A device for applying pressure to a body limb having a primary axis, comprising: a pressure sleeve including a first inflatable cell and a second inflatable cell; and a control unit for determining a treatment program of each inflatable cell and for determining a timing sequence for inflating of each inflatable cell based on the determined treatment program of each inflatable cell; each inflatable cell including at least two intra-cell compartments; said intra-cell compartments being confluent, each intra-cell compartment being elongated in a direction of the primary axis; each inflatable cell further including inner and outer shells of durable flexible material; said inner and outer shells being bonded together to form a perimetric cell bond; said inner and outer shells being further bonded together to form compartmental bonds within said perimetric cell bond, said perimetric bond and said compartmental bonds defining the intra-cell compartment; said perimetric cell bond including upper and lower perimetric cell bonds; said compartmental bonds partly extending between said upper and lower perimetric cell bonds; said compartmental bonds including perforations to allow for confluent airflow between adjacent intra-cell compartments associated with the inflatable cell, adjacent intra-cell compartments being spatially fixed relative to each other, such that upon inflation, the inflatable cell becomes circumferentially constricted; each inflatable cell having a first center point circumference when said intra-cell compartments are deflated and a second center point circumference when said intra-cell compartments are inflated, said second center point circumference being less than said first center point circumference so as to provide for circumferential constriction, said first and second center point circumferences, each being defined as a line passing through each center point of each contiguous intra-cell compartment of the inflatable cell; said compartmental bonds of said intra-cell compartments, during inflation, being drawn towards each other to decrease a distance therebetween and towards the center point of said intra-cell compartments to decrease a distance therebetween, so as to provide for circumferential constriction.
