Abstract
The invention is a modular inflatable/air fluidized patient bed suitable for in-home use. The bed includes a double walled, molded plastic base formed from two pedestals and a connecting midsection. A blower compartment containing the electrical and mechanical components needed to operate the bed is formed in one of the pedestals. The bed optionally includes a plurality of block-shaped spacers that can be positioned under the pedestals to increase the height of the bed. A series of pilot operated check valves are provided in the air lines leading to the inflatable components. If air flow is interrupted, the check valves close to maintain the air in the inflatable components and prevent them from deflating.
