GENERAL

INFORMATION

The 

Duke System

 is an alternating pressure relieving mattress system used in the prevention 

and treatment of pressure ulcers, and is recommended for use by a patient who is at risk from 

developing pressure sores. The mattress is fitted with a vapour permeable two way stretch 

cover. 

By using the established principles of alternating therapy, the 

Duke System

 offers the patient 

comfortable and relaxing support that can both prevent tissue breakdown and enhance 
healing.

The

 Duke Pump

 unit is lightweight and compact; its features include an audible and visual 

low-pressure warning, intergrated battery backup and a manual pressure / comfort control 
function. 

The 

Duke Mattress

 is made up of 30 individual cells. 25 alternating air cells and 5 static cells 

at the head end. The alternating cells are split into 2 sections - odd cells e.g. 1,3,5 etc and 
even cells e.g. 2,4,6 etc. These two sections will alternate through a 10 minute cycle in which 

time both sets of air cells will have inflated and deflated sequentially. All air cells are individually 

replaceable should any damage occur. 
The quick release 3 pipe connector complete with transport cap enables easy patient 

transport arrangements. For rapid deflation of the system simply twist open the CPR.

The 

Duke Extra Mattress

 is based on the Duke Replacement Mattress System with an 

additional foam surround, suitable for wider beds The mattress has 25 alternating air cells and 
3 static cells at the head end. Available in 1200mm and 1370mm width, the mattresses have 
an increased maximum weight limit of 50 stones / 317 kg. The surround is visco topped for 

comfort and can be used on a profiling bed.
