Abstract
A controller for applying sequential compression to a patient's limb includes a variable speed motor connected to a rotary vane pump, and an electronic control circuit to drive the motor at a speed which will in turn drive the pump at a corresponding speed to provide intended output pressure. The controller provides automatic regulation of preset pressure and operates in a fully automatic manner. The controller is contained within a compact housing which can be floor or bed mounted and which has an output connector integral with a unitary manifold assembly for coupling to a tubing set by which sequentially pressurized air is directed to respective compartments of one or more compression sleeves disposed about a patient's limbs.
