Abstract: Systems and methods include a test media, a reservoir containing fluid, and a sensor compared to measure a parameter that is related to an amount of fluid in the test media. Systems and methods may include a comparator to compare the parameter measurement to a parameter set point. Systems and methods may include a control system to control the addition of the fluid to the test media so that the parameter is maintained at a steady state value.

Abstract: A patient support system particularly suited for pediatric twin separation surgery. The patient support system includes a frame coupled to a swing circle that has a plurality of holes about the perimeter. A patient support structure is coupled to the swing circle, and disposed in a fixed relationship to the frame after rotation of the swing circle relative to the frame. A chain-and-sprocket mechanism is coupled to the frame and swing circle and positioned within the frame. At least one support leg depends from the frame, and may extend or retract relative to the frame. A drape cage is coupled to the frame for supporting a surgical drape thereon. At least one support wheel is connected to the support leg, and adapted to be interchangeably fixed in a static position and rotatable to move the frame. A substantially identical second frame may be connected in series to the frame for operative procedures.

Abstract: Apparatus, systems, and methods to support a patient or other person include a first material that is substantially air impermeable welded to a second material that is substantially air permeable and liquid impermeable. The first material may also be liquid and vapor impermeable and the second material may be vapor permeable. Exemplary embodiments may include an inflatable enclosure formed from a sheet of the first material with an aperture, and the second material may cover a portion of the aperture.

Abstract: In various embodiments, a support system includes a multi-layer cover sheet with a number of layers. In certain embodiments, a source to move air inside and outside the multi-layer cover sheet can be provided. The source can include a source of positive pressure or negative pressure.

Abstract: A system and method for a bed transport. The system may include a drive system configured to couple to a bed frame and to provide powered movement of the bed frame. The system may also include a substantially vertical control arm and a control handle coupled to the control arm. The system may also comprise a switch on the control handle, and the switch may be configured to control a function of the drive system.
