Title:
IMPROVED INTERMITTENT PNEUMATIC COMPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/134939
Kind Code:
A3
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.
