Abstract The mattress includes a hollow, elongated, fluid-inflated mattress body which may be permanently inflated or inflatable and deflatable by connection with a suitable inflation device. The mattress also includes a selectively inflatable patient support component which is disposed generally centrally of the mattress body and is connected thereto. The support component includes a number of cells which are individually connected to a device capable of individually inflating and deflating each of the cells to facilitate support of the patient's body, while lying on the mattress, and to minimize the development of bed sores. The support component inflation device preferably is both manually and automatically controlled. The support component's cells may be elongated, parallel, preferably transversely extending tubes, or a grid of inflatable pockets or the like. In one embodiment, the mattress body comprises a number of contiguous, longitudinally extending tubes connected to a manifold and simultaneously inflatable and deflatable. The mattress has improved properties over conventional inflatable mattresses.
An improved inflatable bed patient mattress, said mattress comprising, in combination: (a) a hollow elongated air-inflated mattress body, at least the main portion of which is inflatable and deflatable as a single unit to a uniform pressure; (b) a selectively air-inflatable patient support component disposed generally central of, totally surrounded by said mattress body and connected thereto, said support component being disposed at a location and being in a size to underlie those portions of a patient's body, when lying on said mattress body, which extend from about the lumbar spinal region to the upper thigh region; said patient support component including a plurality of individually air inflatable cells; and, (c) support component inflation means individually connected to each of said cells for both manually controlling selective powered air inflation and deflation of said cells to individual pressures and for automatic cycling of powered inflation and deflation of said cells to individual pressures to facilitate patient body support and minimize development of decubitis ulcers.
