Patent ID: 8597194

Claim:
A system for diagnosing and preventing, deep vein thrombosis in a body limb, comprising: a compression system for applying external pressure to a body limb and for generating a venous phasic flow signal, said venous phasic flow signal being indicative of a venous phasic flow in a body limb; and a venous phasic flow monitoring system to monitor said venous phasic flow signal over a time period to determine changes in said venous phasic flow signal over the time period and to determine a presence of deep vein thrombosis in the body limb based on changes in said venous phasic flow signal over the time period; wherein said compression system includes a pressure sleeve including a plurality of individually fillable cells, surrounding the body limb, to measure a pneumatic pressure change caused by a change in a volume of the body limb within said pressure sleeve; said compression system further includes a source to fill each fillable cell individually; said source fills a first individually fillable cell of said pressure sleeve to a predetermined pressure and fills a second individually fillable cell of said pressure sleeve while said venous phasic flow monitoring system monitors said venous phasic flow signal associated with said first individually fillable cell of said pressure sleeve.
