Australian Standard Medical Grade
Sheepskins
A remarkably effective solution available for pressure
ulcer prevention is the Australian Medical Sheepskin.
One of the most difficult to treat medical conditions arising from long term immobility is the very likely
occurence of decubitis ulcers, otherwise known as pressure sores or pressure ulcers.
Those people confined to a wheelchair or bed for extended periods or permanently, are particularly at risk of
suffering pressure ulcers.
Pressure ulcers (decubitis ulcers) are a frequent occurrence in many Australian health institutions.
Pressure sores show as tissue breakdown due to prolonged compression with consequent reduction in capillary
blood flow in the tissue between the person's boney prominences and the surface they lay or sit upon. The direct
causes are pressure at susceptible points, friction or shear forces at the point of contact between the patient and
the support surface and a build up of moisture or humidity at the interface surface.
During 1997 the CSIRO - in partnership with industry - developed new technologies and standards to enable
production of long life, high performance, medical sheepskins particularly suitable for prevention of pressure
ulcers. The sheepskins reduce pressure, friction, and excess moisture (which can cause chafing).
The Australian Standard AS 4480.1-1997 was introduced to provide a regulated environment for quality control of
sheepskins used in the health care industry. Prior to the introduction of the Australian Standard, it was extremely
difficult for the licensing authority (the International Wool Secretariat) to properly manage the quality and
effectiveness of the various sheepskins claiming therapeutic benefits.
The Australian Standard defines the size of the sheepskin, the performance criteria, and the wool
characteristics. The mandatory label which is attached to the underneath of the sheepskin will also include the
Manufacturers identification code.
An Australian Medical grade sheepskin can be laundered many times over at wash temperatures up to 80 degrees
Centigrade, thus achieving high level disinfection that will meet hospital infection control standards. At these
high temperatures, thermal disinfection is easily achieved with the tanning technology ensuring a stable leather
for a long life over many wash/dry cycles - 50 plus cycles are possible based upon CSIRO tests.
Wool type, wool length and the final finish are important elements of the performance criteria. The unique
properties of sheepskin having between 4,000 and 6,000 fibres per square centimetre cannot be replicated by
manufacturing technology. Each wool fibre is uniquely and individually held intact by the tanned skin of the
sheep, contributing to its value as a medical product and distinguishing the genuine sheepskin from its many
manufactured imitations. Interfaced between patient and the contact surface, they reduce pressure, friction and
moisture – the primary causes of pressure sores.
The sheepskin is manufactured from Merino crossbreed sheep with finished staple length of 30mm to achieve a low
friction coefficient. Its high density of soft springy and resilient fibres, provides a cushion to distribute and
relieve pressure at vulnerable pressure points on the person’s body, allowing for cooling air movement between
their skin and the leather of the sheepskin.
Uniquely, wool fibres can absorb up to 34% of their dry weight in moisture without feeling damp, rapidly
dissipating this moisture away from the source. This is a cause of great comfort to immobile or incontinent people,
where moisure is caused by perspiration or urine.
The performance criteria for medical sheepskin complying with the Australian Standard is arguably the most
demanding made of any leather product.
When purchasing an Australian Standard branded medical grade sheepskin, you can be assured you are buying the
very best possible prevention for pressure ulcers. Mobility Rentals & Sales is proud to be able to provide
these quality high performance sheepskins to their customers.
