ABSTRACT:
The invention relates to a device comprising a mattress support intended to be placed underneath a mattress or the like, to facilitate the care of bedridden patients. The support consists of a number of sections (1), each comprising a rigid board (4) or the like, extending essentially fully across the width of the support, and underneath each such board at least two inflatable cells (13a, 13b), of which at least one is placed on each side of an imaginary center line (14) along the support (21). The sections are adjoining along their adjacent edges (2), said joint being articulate and/or permitting the disassembly and reassembly of the support, and the inflatable cells on each side of said center line are inflatable independently and optionally, thus providing for a slow rocking of a patient lying on the bed, via the rigid boards and the mattress (23) on top of the support, thereby causing a redistribution of the areas of pressure between the mattress and the patient which in turn counteracts the formation of bed sores and/or provides a certain massaging effect.
