Abstract
An automatic portable ambulant miniaturized system for applying pneumatic pressure to a body limb including a portable ambulant hand-held fluid source unit, a conduit for delivering fluid generated by the unit, and a sleeve coupled to the conduit and adapted to envelop a body limb. The sleeve contains one or more individually inflatable cells, each cell being subdivided into two or more longitudinally extending confluent compartments along the axis of the body limb. The compartments are inflated and deflated essentially simultaneously by the portable fluid source unit.
Claims41
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.
