Inflatable patient supports

摘要

An inflatable body support has an array of inflatable cells, inflation means for inflating the cells and control means controlling inflation and deflation of the cells. The cells are in groups, and the control means has a normal operation mode in which it effects cyclical inflation and deflation of each group in a predetermined cyclical sequence with the sequences for the respective groups being out of phase. The control means has a second operation mode which is selectable by an operator during said normal operation mode and in which all the groups of cells are maintained inflated by connection to the inflation means and deflation of each said group is suppressed.
