Abstract
A plurality of pairs of inflatable air cells disposed on opposite sides of a longitudinal axis are arranged along the length of a bed. Each of the air cells extends substantially transverse to the longitudinal axis and are supplied with air so that cells on alternate sides are inflated while simultaneously the cells on the other side are deflated. An upper layer of a resinous foam pad is provided on which the patient lies. The pad is provided with a groove along its longitudinal axis for comfort of the patient. The assembly is completed by a covering having an upper sheet member removably attached to a lower sheet member so that when soiled it may be easily removed.
Claims8
An anti-decubitus, pneumatic mattress comprising a bottom assembly of a plurality of inflatable, rectangular mattress cells disposed in edge-to-edge relationship in two rows on opposite sides of a longitudinal axis, each of said mattress cells being formed of a non-elastic base and a semi-cylindrical, distendible cover sealed about its edge to the base defining an inflatable air chamber, each base being provided with means for removably attaching said cells in said edge-to-edge relationship and conduit means entering into said air chamber adjacent the unfastened edges of said cells,
- a top assembly comprising a foam pad overlying the entire extent of said bottom assembly, said foam pad having a single groove on its upper surface extending along the longitudinal axis in alignment with the space between the two rows of mattress cells, and
- means for alternately supplying air to each of the mattress cells in one of said two rows while simultaneously withdrawing air from each of the mattress cells in the other of said two rows.
