Abstract
A person-support apparatus for use with a suction source comprises a core having a one or more foam elements and a cover having an interior region in which the core is situated. The cover is in fluid communication with the suction source and the suction source operates to evacuate a portion of air from the interior region so that at least one of the foam elements is partially compressed within the interior region of the cover due to the evacuation of the portion of air.
Claims72
A person-support apparatus for use with a suction source, the person-support apparatus comprising
- a core having a first foam element, the first foam element having a vertical thickness, a horizontal length, and a horizontal width, the vertical thickness being smaller than both the horizontal length and the horizontal width when the first foam element is in an uncompressed state, and
- a cover having an interior region in which the core is situated, the first foam element filling at least a majority of the interior region, the cover having an opening in fluid communication with the suction source, the suction source operating to evacuate a portion of air from the interior region so that the first foam element is partially compressed within the interior region of the cover due to the evacuation of the portion of air.
A person-support apparatus for use with a suction source, the person-support apparatus comprising
- a core having a first foam element,
- a cover having an interior region in which the core is situated,
- a first conduit coupled to the cover, the first conduit being in fluid communication with the interior region, and
- a pressure regulator coupled to the conduit and coupled to the suction source, the suction source operating through the pressure regulator to evacuate a portion of air from the interior region so that the at least one foam element is partially compressed within the interior region due to the evacuation of the portion of air, the pressure regulator being configured to establish a preset negative pressure in the interior region.
A person-support apparatus for supporting a patient in a hospital room having an outlet that is coupled to a suction source, the person-support apparatus comprising
- a core having a first foam element,
- a cover having an interior region in which the core is situated,
- a first conduit coupled to the cover, the first conduit being in fluid communication with the interior region,
- a pressure regulator coupled to the first conduit, and
- a second conduit coupled to the pressure regulator and adapted to couple to the outlet in the hospital room, wherein when the second conduit is coupled to the outlet, a negative pressure having a magnitude established by the pressure regulator is created in the interior region of the cover to evacuate a portion of air from the interior region to partially compress the foam in the interior region.
