Mattress Overlay Systems (OL)
A typical mattress overlay (OL) system is shown in Figure 1. It includes a base sheet, alternating and
static cells (which are individually replaceable), a cover, air inlet tubes (with connectors where
applicable) and a Cardiopulmonary Resuscitation (CPR) pull tag (also referred to as a Rapid Deflate
stopper). The cell configurations are detailed in Table 2.
The AlphaXcell Double Mattress system is a double inflatable mattress overlay, which provides static
pressure to one side and alternating pressure relief to the other side. The static and alternating sides of
the mattress can be set up on either side of the bed depending on customer requirements.
The Trancell system is an exception. The cells for the Alpha Trancell system are not individual
replaceable cells but are a one-piece manufactured item and can only be replaced as a complete item.
