Abstract
An inflatable cushion cell has first and second inflatable compartments. Each inflatable compartment is defined by at least one diagonal seal structure. In addition, each inflatable compartment also has at least one fluid opening. In one embodiment the diagonal seal structure is offset from opposite corners of the inflatable cushion cell. In one embodiment patient support system includes a plurality of inflatable such cushion cells are located within a frame. In one embodiment a pressure control system is used control the inflation of the first and second inflatable compartments. In one embodiment a method is used to move a patient in an inflatable patient support system, such as a support system that employs an inflatable cushion cell with a diagonal seal structure.
Claims6
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.
A method of moving a patient in an inflatable patient support system comprising:
- adjusting a pressure of a plurality of inflatable cushion cells wherein each of the plurality of cushion cells includes at least one diagonal seal structure that defines at least in part, a first inflatable compartment and a second inflatable compartment, by providing a higher pressure in respective first compartments and a lower pressure in respect of second compartments;
- and
- changing the pressure in respective first and second compartments of the plurality of cushion cells and wherein the diagonal seal structure is formed as a seam that defines first and second external side walls of each of the first and second compartments.
