Abstract:
1. A method of moving a patient in an inflatable patient support system comprising: reducing pressure in a first inflatable compartment of an inflatable cushion cell that includes at least one diagonal seal structure that defines at least in part the first inflatable compartment and a second inflatable compartment, by removing a desired amount of fluid from the first inflatable compartment via a first fluid opening; equalizing pressures in the first inflatable compartment and the second inflatable compartment by providing fluid communication between the first and a second fluid opening; increasing pressure in the first inflatable compartment to a high pressure by introducing fluids to the first inflatable compartment via the first fluid opening; reducing pressure in the second inflatable compartment by removing a desired amount of fluid from the second inflatable compartment via the second fluid opening; equalizing pressures in the first inflatable compartment and the second inflatable compartment by providing fluid communication between the first and second fluid openings; increasing pressure in the second inflatable compartment to a high pressure by introducing fluid to the second inflatable compartment via the second fluid opening.
