General Description
The mattress replacement, overlays and seat systems identified in Table 1 are designed specifically to aid in the prevention, treatment and management of pressure ulcers. They are air-filled, alternating pressure mattress and seat systems powered by air pumps. Some of the pumps provide an option of microprocessor aided control and sound alarm functions and have LED indications on the front panel. The mattresses can be used on standard hospital and normal domestic beds. The seat cushions can be used on standard hospital and normal domestic chairs.

Introduction
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.

Mattress Replacement Systems (MR)
A typical mattress replacement (MR) system is shown in Figure 2. The MR systems are basically the same configuration as the OL systems with the addition of a foam base which replaces the normal bed mattress. The foam base provides a safety and transport function should the air supply fail or the alternating cells deflate. The cell configurations are detailed in Table 2.

Operating Principles
Refer to Figure 4 for a typical pneumatic system diagram and cell inflation cycle, and Table 2 for the actual cell configurations. All pumps have two pressurised air outlets. Air from the outlets is fed to separate cells or groups of cells in the mattress or seat cushion via a rotary valve. The mattress or seat cushion support cells are continuously inflated and deflated during a ten minute cycle. During the cycle, air is pumped from one outlet to cells “A” (or “B”) for 4 minutes and 10 seconds. This is followed by a period of 50 seconds when air is pumped from both outlets to cells “A” and “B”. Subsequently, air is pumped from the other outlet to cells “B” (or “A”) for 4 minutes and 10 seconds, and then a further 50 seconds with air from both outlets to cells “A” and “B”. During the period when air is pumped from an outlet to one group of cells, the second set of cells is slowly vented to atmosphere, causing them to reduce pressure. In some of the mattress replacements or overlays, there is a third set of cells labelled “C”, which are supplied from a static feed. This static feed “C” is generated by two partial non-return valves (in the mattress manifold assembly) from alternating feeds “A” and “B”, and is therefore never at zero pressure. Where fitted, the “C” cells are normally in the head section of the mattress, to provide a stable pillow section and prevent the patient’s head from rising and falling.

Introduction
Rapid Deflation of the Overlay or Mattress Replacement
Most, but not all, mattress replacement and overlay systems have a cardiopulmonary resuscitation (CPR) or Rapid Deflate plug to allow rapid deflation of the mattress replacement or overlay system. None of the seat systems have a CPR (or Rapid Deflate) plug. The CPR (or Rapid Deflate) plug is located at the head end of the overlay or mattress replacement, on the same side as the tubeset (refer to Figure 5). For rapid deflation of the overlay or mattress replacement in an emergency, pull the CPR (or Rapid Deflate) tag to remove the CPR (or Rapid Deflate) plug from the manifold. To re-inflate the overlay or mattress replacement, replace the CPR (or Rapid Deflate) plug securely, reconnect the manifold tubes to the pump, and switch on.

Carry out the Mattress/Seat System Maintenance Checks (Refer to Page 1, Section 2).
1.2
Carry out the Pressure and Function Test on the mattress or seat system in accordance with Chapter 5, Page 1, Section 1.
2

CHAPTER 3 REPAIR 1
General
This chapter details the repair procedures for the range of mattress and seat systems identified in Chapter 1, Page 2, Table 1. All repairs should be carried out by Huntleigh approved service personnel. The repair procedures in this chapter are general and not unique to a product. Refer to Table 3 first to identify the relevant assembly drawing and parts list for the product being repaired, and then refer to them whilst carrying out the repair procedures detailed in Section 3 onwards of this chapter. It is easier to carry out the repair procedures if the mattress or seat system is fully deflated first. Disconnect the tubeset between the mattress or seat system and the pump to deflate it. After carrying out a service or any repairs on the mattress or seat system, but before installing the top cover, check the following: 1.1
All press studs on the mattress, overlay or seat system are connected.
1.2
All cells are evenly positioned in their loop straps. The repair will normally have disturbed the position of the cells, and they should be re-positioned evenly.
After carrying out a service or any repairs, the mattress or seat system must be tested for serviceability, by carrying out the Pressure and Function Test on the mattress or seat system in accordance with Chapter 5, Page 1, Section 1.
