Short Description

The Supra Overlay Kit consists of a mains powered alternating air system, a pump and a two way stretch cover. It is designed for users who are at low to medium risk of developing pressure sores. It has seventeen air cells that alternate on a 9.6 minute cycle. The pump has a pressure adjustment dial. The three cells at the head end do not alternate and form the pillow.

Method Of Use

1. Place the overlay on the bed and inflate until it feels firm, with minimal give when pressed. Once inflated, tuck in the end flaps.
2. Position the user on the overlay.
3. Place one hand under the user, where the overlay is most compressed (ie under bony prominences of the bottom / pelvis).
4. Choose an air cell which is in the compressed cycle.
5. Turn your hand so it is facing sideways and slide your fingers along the cell.
6. If you are unable to slide a hand under the user the pump output will need to be increased. If there is excessive space between the user and the bottom row of cells the pump output will need to be reduced.

More Details

The system consists of a portable pump unit and an overlay made from nylon, laminated with polyurethane with tuck in flaps at the head and foot ends. A separate mattress cover completes the system.

The overlay features individual cylindrical air cells that span the full width of the overlay. The cells press stud into place and are separate from the overlay base and each other so that they can be removed and replaced if punctured.

The pump supplies air to each alternate cells in a nine minute cycle of alternative inflation and deflation. The three air cells at the head end remain at a constant pressure to minimise the sensation of movement for the user. The cells in the main trunk area feature low air loss, designed to improve air circulation around the user and reduce perspiration.

FEATURES

COVER a separate, water resistant cover with two way stretch is provided. This cover is breathable (vapour permeable) and has microbial properties. It lies over the top of the mattress and attaches to head and foot of the overlay with press studs.

STRUCTURE consists of 17 air cells. Individual air cells can be removed if punctured, for repair or replacement. There are low air loss cells in the main trunk area which are designed to maximise air circulation around the client and minimise perspiration.

ATTACHMENT has tuck in flaps, and securing straps with hook and loop fastening, which can be secured underneath the existing mattress or underneath the mattress overlay.

PUMP / CONTROLS a separate, portable alternating pressure pump features an on / off switch and a manually operated pressure control dial which sets the required level of air pressure. There is a written guide on side of the pump for reference. The pump has a bracket attachment to enable it to be hung on the bed frame if desired.
Pressure range..............30-80mmHg
Pump output.................4 Litres/minute

SAFETY FEATURES The pump features a low pressure warning signal, which is audible and visible, and indicates pressures 5mmHg less than set pressure. The overlay has an emergency CPR release handle, which allows rapid deflation of the mattress for coronary pulmonary resuscitation. The air hoses have spring loaded CPC connectors which minimise accidental disconnection.

Factors To Consider

All pressure reduction products must be monitored to prevent 'bottoming out'. This occurs when the user's weight bears down so hard on the product material that it is flattened and the bony parts are pressed against the surface below the cushion or mattress. Where bottoming out occurs even with correct use (eg correct inflation levels), a different product may need to be considered.

Maintenance

CLEANING REQUIREMENTS
Wipe clean with non phenyl based cleaning fluids.

Standards

Some assistive technology needs to meet Australian or other standards. Standards may relate to materials, manufacturing and installation. Products that meet Australian or international standards will have written certification. To find out if a product meets Australian Standards ask the supplier to show you the certificate.
