593669 Pressure Controller A pressure controller for controlling fluid pressure in an alternating pressure pad which comprises means (4) sensitive to the fluid pressure and adapted to open a valve (15) when the pressure exceeds a predetermined value, fluid supply means (8) connected at one end to said valve (15) and at the other end being adapted for connection to a pump (6) for inflating the pad, the fluid supply means (8) being arranged, in use, to receive pressure exerted by a patient on the pad and to be compressible in dependence upon the pressure exerted by the patient to reduce the escape of fluid from the valve (15) when the valve (15) is open. Thereby, causing a proportion of fluid to continue to inflate the pad. |
