Inflatable support
View Patent ↗An alternating pad consisting of transverse inflatable cells ( 1 and 2 ) alternately inflated and deflated. An internal cell ( 5 ) is provided at the outermost edges of each transverse cell ( 1,2 ). The internal cell ( 5 ) is constantly inflated at a higher pressure than the traverse cells ( 1, 2 ). The internal cell ( 5 ) is at a lower height than the cells ( 1,2 ) and preferably of a chamfered shape to provide optimum pressure relief across the whole surface of the pad. The internal cell ( 5 ) provides stable patient exit, entry or transfer from a bed or seat.
1. An inflatable support for providing pressure relief, the inflatable support comprising at least one undivided inflatable transverse cell extending transversely of the support, each at least one transverse cell having opposite ends and within each said opposite end at least one internal cell, each at least one internal cell at a higher pressure than the transverse cell and having a lower height than the transverse cell, such that the whole of an upper surface of the transverse cell provides pressure relief.
2. The inflatable support of claim 1 , comprising a plurality of transverse cells, inflated and deflated alternately.
3. The inflatable support of claim 1 , wherein the at least one internal cell is constantly inflated.
4. The inflatable support of claim 1 , wherein the at least one internal cell is chamfered at least one internal edge.
5. An inflatable support comprising at least one inflatable transverse cell extending transversely of the support, the at least one transverse cell having outermost opposite ends and within each said outermost opposite end at least one internal cell at a higher pressure than the transverse cell, the at least one internal cell having a lower height than the transverse cell and filled with foam material.
6. An inflatable support comprising at least one undivided inflatable transverse cell extending transversely of the support, the at least one transverse cell having opposite ends and within each said opposite end at least one internal cell at a higher pressure than the transverse cell, the least one internal cell at each opposite end of the transverse cell having a lower height than the transverse cell and connected by a common manifold and inflated jointly by that manifold.
7. An inflatable support comprising at least one inflatable transverse cell extending transversely of the support, the at least one transverse cell having outermost opposite ends and within each said outermost opposite end at least one internal cell at a higher pressure than the transverse cell, the least one internal cell at each opposite end of the transverse cell having a lower height than the transverse cell and connected by a common manifold and inflated jointly by that manifold, wherein the manifold is of foam.
8. An inflatable support for providing pressure relief, the inflatable support comprising at least two sets of cells extending transversely of the support, the sets alternately inflatable and deflatable to alternately provide pressure relief and support for a patient supported on the support, each at least one transverse cell extending across a center of a width of the support and having outermost opposite ends, and within each said outermost opposite end at least one internal cell, each at least one internal cell at a higher pressure than the transverse cell and having a lower height than the transverse cell.
