An electrically-powered device intended to be used for the noninvasive treatment and prevention of venous disorders/sequelae. As part of a compression system, the pump provides the connected stocking/sleeve/suit applied to the extremities with the necessary pressure to promote venous blood flow through its sequential inflation and deflation. Also referred to as a pump, it typically consists of a compressor with advanced control/timing mechanism, pressure limiting device, tubing, and connectors. The resulting increased venous blood flow may help to treat/prevent oedema, deep vein thrombosis (DVT) and pulmonary embolism (PE) in non-ambulatory patients or patients at risk.
