DRIVE SYSTEM FOR CONTROLLING CARDIAC COMPRESSION

摘要

This invention is an inflation system (50) for independently controlling the pressure profile, namely the rise time and plateau level of fluid supplied to an inflatable chamber (18) by a fluid source (56) by means of fluid passages (52, 54) leading to high and low pressure regulators (58, 60), and tanks (62, 64) whose outputs are controlled by valves (66, 68) to provide the required high and low pressures at specific times to define the pressure profile.
