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.
Claims23
An inflatable cushion cell comprising:
- first and second inflatable compartments defined at least in part by at least one diagonal seal structure;
- wherein each compartment includes at least one fluid opening and wherein the cushion cell is non-annular.
An inflatable cushion cell comprising:
- first and second inflatable compartments defined by at least one diagonal seal structure, wherein each compartment includes at least one fluid opening, wherein the first and second inflatable compartments each have at least one base surface and at least one leg surface located opposite the diagonal seal structure, and wherein at least one of the base surface and the leg surface is defined by a seal;
- and
- a restriction member located away from the diagonal seal structure wherein the restriction member is formed as a seam to restrict the expansion of the first and second inflatable compartments.
An inflatable cushion cell defined by offset four corners comprising:
- first and second inflatable compartments defined by at least one diagonal seal structure, wherein each compartment includes at least one fluid opening;
- wherein the diagonal seal structure is offset from opposite corners of the cell.
An inflatable patient support system comprising:
- a frame for securing inflatable cushion cells;
- and
- a plurality of inflatable cushion cells located within the frame;

- a plurality of inflatable cushion cells located within the frame;
- wherein at least one of the plurality of inflatable cushion cells includes first and second inflatable compartments defined at least in part by at least one diagonal seal structure, and wherein each compartment includes at least one fluid opening, wherein each of the first inflatable compartments of the plurality of inflatable cushion cells are in fluid communication with one another;
- and wherein each of the second inflatable compartments of the plurality of inflatable cushion cells are in fluid communication with one another;
- and
- a pressure control system including:
- a user interface device for selecting desired pressures for the first inflatable compartments and the second inflatable compartments;
- a pressure sensor for detecting pressures of the first inflatable compartments and the second inflatable compartments;
- a fluid pump for selectively increasing or decreasing the pressures in the first inflatable compartments and the second inflatable compartments;
- a valve assembly for selectively providing fluid communication to the first inflatable compartments and the second inflatable compartments;
- and
- a controller for controlling the operation of the fluid pump and the valve assembly based on input from the user interface device and the pressure sensor.
An inflatable cushion cell comprising:
- first and second inflatable compartments defined at least in part by at least one diagonal seal structure, wherein each compartment includes at least one fluid opening;
- and
- a plurality of securing structures.
