Abstract: An intermittent pneumatic compression (IPC) device includes a user interface allowing selection among different categories of circulation insufficiency. After one of the categories is selected the possible range for the treatment parameters are limited. The disclosed device includes an intermittent pneumatic compression device that has lockable, adjustable treatment parameters. A lockout mechanism activates after selection of the parameter values, preventing the patient from changing the selected values. The lockout mechanism requires an access device to make further changes to the values. An inflatable cuff for the foot includes both a zipper and hook-and-loop fasteners to maintain tension during compression and wherein the zipper can be opened to remove said cuff while preserving the hook-and-loop fastener relationship so that when the cuff is placed back into position and the zipper closed, the fixed adjustable dimension of the combination will be restored.

Abstract: Intermittent pneumatic compression (IPC) devices facilitate fluid circulation in a body by providing alternating higher pressure and a lower or no pressure in an associated inflatable cuff. A source of air at a pressure less than 130% of the higher pressure at the inflatable cuff communicates to the inflatable cuff through a large-cross-section, continuously-open passageway. A large vent valve on that passageway opens for a lower or no pressure condition and closes to achieve a higher pressure within 0.1 second. For the lower or no pressure state, the vent valve not only vents the inflatable cuff, but also vents continuing air flow from the source of air pressure, until the next rapid pressure rise. The periods between successive compressions are from 2 to 10 seconds, with compressions from 0.35 to 5 seconds. While most of the inflatable cuff is not transparent, portions adjacent the heel and toes are.

Abstract: Intermittent pneumatic compression (IPC) devices for facilitating fluid circulation in a body are disclosed. The disclosed devices provide compression by alternating between a higher pressure and a lower or no pressure in an associated inflatable cuff. The devices are configured to have a source providing air at a pressure less than 130% of the higher pressure at the inflatable cuff. A vent valve is coupled to a passageway communicating with the pressure source whereby the vent valve can be opened when a lower or no pressure condition in the inflatable cuff is desired, and can close when the higher pressure is desired. With this arrangement, the vent valve not only vents the inflatable cuff, but also vents continuing air flow from the source of air pressure.
